                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by and should be read in
conjunction with the more detailed information and the Consolidated Financial
Statements and the Notes thereto appearing elsewhere in this Prospectus. Unless
otherwise indicated, all references to the Company's authorized, issued and
outstanding securities assume no exercise of the Underwriters' over-allotment
option. This Prospectus contains forward-looking statements that involve risks
and uncertainties. The Company's actual results may differ materially from the
results discussed in the forward-looking statements as a result of the factors
set forth under "Risk Factors" and elsewhere in this Prospectus.
 
                                  THE COMPANY
 
     Manchester Equipment Co., Inc. is a systems integrator of computer
hardware, software and networking products, primarily for commercial customers.
The Company offers its customers single-source solutions customized to their
information systems needs by combining value-added services with hardware,
software, networking products and peripherals from leading vendors. Over the
past 20 years, the Company has forged long-standing relationships with both
customers and suppliers and has capitalized on the rapid developments in the
computer industry, including the shift toward client/server-based platforms.
Each year during this period, the Company has been profitable and has generated
growth in revenues.
 
     Manchester's marketing focus is on mid- to large-sized companies, which
have become increasingly dependent upon complex information systems in an effort
to gain competitive advantages. While many of these companies have the financial
resources to make the required capital investments in information systems, often
they do not have the necessary information technology personnel to design,
install or maintain complex systems or to incorporate continuously evolving
technologies. As a result, these companies are turning to independent third
parties to procure, design, install, maintain and upgrade their information
systems.
 
     The Company offers its customers a variety of value-added services, such as
consulting, integration and support services, together with a broad range of
computer and networking products from leading vendors. Consulting and
integration services include systems design, performance analysis, security
analysis, migration planning, product procurement, configuration, testing and
systems installation and implementation. Support services include network
management, "help-desk" support, and enhancement, maintenance and repair of
computer systems. The Company's customers include Barnes & Noble Inc., Cabletron
Systems Inc., Conde Nast Publications Inc., J&R Music World, National
Broadcasting Company Inc., Pfizer Inc., Reuters America Inc., Sotheby's Inc.,
Time Warner Inc., The Toronto Dominion Bank, United Parcel Service of America
Inc. and the United States Merchant Marine Academy. The Company offers services
and products from its headquarters in Long Island, New York, and its regional
offices in New York City, Needham (Boston), Massachusetts and Boca Raton and
Tampa, Florida.
 
     The Company believes that a number of factors enable it to compete in a
highly competitive and rapidly changing market. Among other things, the Company
benefits from long-standing relationships with many of its customers, providing
opportunities for continued sales of products and services. The Company's long-
standing relationships with suppliers and its large volume purchases contribute
to the Company's ability to obtain significant purchase discounts and inventory
as needed. Manchester further believes that its name is widely recognized for
high quality, competitively priced products and value-added services. Manchester
also has developed efficient inventory and credit extension controls which have
historically resulted in rapid inventory turnover and minimal bad debt expense.
The Company's expansion to regional offices in the Northeast and Florida has
further contributed to the continued increase in its revenues.
 
     Key elements of Manchester's strategy include (i) increasing its focus on
providing value-added services, such as consulting, integration and support,
(ii) expanding its marketing focus on companies outside the Fortune 500, (iii)
introducing an electronic sales ordering system (linked to automated inventory
and credit control systems) for its customers, (iv) increasing sales force
productivity through enhanced electronic access to product information,
increased training of sales representatives and use of telemarketing, (v)
expanding its presence in the New York Metropolitan area by enlarging both its
New York City and Long Island offices
 
                                        3
<PAGE>   5
 
and (vi) expanding geographically into growing business centers in the eastern
half of the United States. In support of its strategy, during the past fiscal
year, the Company hired additional technical and administrative staff and
increased its investment in its management information systems.
 
     The Company's executive offices are located at 160 Oser Avenue, Hauppauge,
New York 11788; its telephone number is (516) 435-1199.

                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, the following risk
factors should be considered carefully in evaluating the Company and its
business before purchasing shares of Common Stock offered hereby. This
Prospectus contains certain forward-looking statements which involve risks and
uncertainties. The Company's actual results could differ materially from the
results anticipated in these forward-looking statements as a result of certain
of the factors set forth in the following risk factors and elsewhere in this
Prospectus.
 
ADVERSE INDUSTRY CONDITIONS; DECREASING OPERATING MARGINS IN SALES OF PRODUCTS
 
     The computer industry is characterized by a number of potentially adverse
business conditions, including pricing pressures, evolving distribution
channels, market consolidation and a potential decline in the rate of growth in
sales of personal computers. Heightened price competition among various hardware
manufacturers has resulted in reduced per unit revenue and declining gross
profit margins. As a result of the intense price competition within the
industry, the Company has experienced increasing pressure on its gross profit
and operating margins with respect to the sale of products. The Company's
inability to compete successfully on the pricing of products sold, or the
continuing decline in its gross margins of products sold due to adverse industry
conditions or competition, could have a material adverse effect on the Company's
business, results of operations and financial condition. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
RISKS ASSOCIATED WITH THE COMPANY'S STRATEGY
 
     An integral part of the Company's strategy is to increase its value-added
services revenue. These services generally provide higher operating margins than
those associated with the sale of products. This strategy requires the Company,
among other things, to attract and retain highly skilled technical employees in
a competitive labor market, provide additional training to its sales
representatives and enhance its existing service management system. There can be
no assurance that the Company will be successful in increasing its focus on
providing value-added services, and the failure to do so could have a material
adverse effect on the Company's business, results of operations and financial
condition. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business -- Strategy -- Emphasizing Value-added
Services."
 
     Manchester's strategy also includes expanding its presence in the New York
Metropolitan area by increasing its sales and service capabilities in its New
York City office and enlarging its sales, service and training capabilities at
its Long Island headquarters as well as expanding geographically into growing
business centers in the eastern half of the United States. There can be no
assurance that the Company's expansion of its New York Metropolitan area
operations will increase profits generated by such operations, that the opening
of new offices will prove profitable, or that these expansion plans will not
substantially increase future capital or other expenditures. The failure of this
component of the Company's strategy could materially adversely affect its
business, results of operations and financial condition. See
"Business -- Strategy -- Expanding New York Metropolitan Area Presence" and
"-- Strategy -- Expanding into Additional Business Centers."
 
     To date, Manchester's success has been based primarily upon sales in the
New York Metropolitan area. The Company's strategy, encompassing the expansion
of service offerings, the expansion of existing offices and the establishment of
new regional offices, is expected to challenge the Company's senior management
and infrastructure. There can be no assurance as to the Company's ability to
respond to these challenges. The failure of the Company to effectively manage
its planned growth could have a material adverse effect on the Company's
business, results of operations and financial condition. See
"Business -- Strategy."
 
     In addition, the success of the Company's strategy will depend in large
part upon the Company's ability to attract and retain highly skilled technical
and sales personnel in a competitive labor market. There can be no assurance
that the Company will be able to attract and retain such skilled personnel. The
loss of a significant number of the Company's existing technical or sales
personnel or difficulty in hiring or retaining additional
 
                                        6
<PAGE>   8
 
technical or sales personnel could have a material adverse effect on the
Company's business, results of operations and financial condition. See
"Business -- Services and Products" and "-- Employees."
 
COMPETITION
 
     The computer industry is characterized by intense competition. The Company
directly competes with local, regional and national systems integrators,
value-added resellers ("VARs") and distributors as well as with certain computer
manufacturers that market through direct sales forces. While the Company's
competitors vary depending upon the particular market, some of the national and
regional competitors of the Company include AmeriData Technologies, Inc.,
CompuCom Systems, Inc., Dataflex Corporation, Entex Information Services, Inc.,
Vanstar Corporation and Electronic Data Systems Corporation. The computer
industry has recently experienced a significant amount of consolidation through
mergers and acquisitions, and manufacturers of personal computers may increase
competition by offering a range of services in addition to their current product
and service offerings. In the future, the Company may face further competition
from new market entrants and possible alliances between existing competitors.
Some of the Company's competitors have, or may have, greater financial,
marketing and other resources, and may offer a broader range of products and
services, than the Company. As a result, they may be able to respond more
quickly to new or emerging technologies or changes in customer requirements,
benefit from greater purchasing economies, offer more aggressive hardware and
service pricing or devote greater resources to the promotion of their products
and services. There can be no assurance that the Company will be able to compete
successfully in the future with these or other competitors. See
"Business -- Competition."
 
DEPENDENCE ON KEY EXECUTIVES
 
     The success of the Company is dependent on the services of Barry R.
Steinberg, the Company's founder, Chairman of the Board, President and Chief
Executive Officer, and Joel G. Stemple, Ph.D., the Company's Executive Vice
President. Mr. Steinberg, who has served the Company for in excess of 23 years,
has long-standing relationships with many manufacturers, which the Company
believes assists it in procuring desired products on a timely basis and on
desirable financial terms. In addition, Mr. Steinberg has long-standing
relationships with many of the Company's customers, providing opportunities for
continued sales of products and services. Dr. Stemple has served the Company for
in excess of 14 years and his management responsibilities include marketing and
advertising programs, review of contracts, monitoring the sales force and
inventory control. The loss of the services of either of Mr. Steinberg or Dr.
Stemple could have a material adverse effect on the Company's business, results
of operations and financial condition. See "Management."
 
DEPENDENCE UPON MAJOR CUSTOMER
 
     The Company's largest customer accounted for approximately 14%, 22% and 16%
of the Company's revenues for the fiscal years ended July 31, 1994, 1995 and
1996, respectively, substantially all of such revenues being derived from the
sale of hardware products. The presence of this customer contributes to the
Company's ability to obtain volume discounts on the purchase of computer
hardware from certain of its vendors. Although this customer has been a customer
of the Company for approximately ten years, the Company has no long-term supply
contract with it, but rather ships products against purchase orders to meet the
customer's needs. The loss of this customer could have a material adverse effect
on the Company's revenues as well as its ability to obtain volume discounts from
certain vendors, either of which could have a material adverse effect on the
Company's business, results of operations and financial condition. See
"Business -- Services and Products" and "-- Customers."
 
DEPENDENCE ON SALES TO COMPUTER RESELLERS AND VARS
 
     The Company's profitability has been affected by its ability to obtain
volume discounts from certain manufacturers which has been dependent, in part,
upon the Company's ability to sell large quantities of products to computer
resellers, including VARs. Sales to resellers have been made at profit margins
generally less favorable than sales directly to commercial customers. For the
fiscal years ended July 31, 1994, 1995 and 1996, approximately 25%, 24% and 23%
of the Company's revenues, respectively, were derived from sales to
 
                                        7
<PAGE>   9
 
computer resellers, including VARs. The Company's inability to continue to sell
products to computer resellers and thereby obtain the desired volume discounts
from manufacturers or to expand its sales to commercial customers sufficiently
to offset the need to rely on sales to computer resellers could have a material
adverse effect on the Company's business, results of operations and financial
condition. See "Management's Discussion of Financial Condition and Results of
Operations."
 
DEPENDENCE ON MAJOR MANUFACTURERS
 
     The Company's business is dependent upon its relationships with major
manufacturers in the computer industry. Combined sales of products manufactured
by Toshiba America Information Systems, Inc. ("Toshiba"), Hewlett-Packard
Company ("Hewlett-Packard"), NEC Technologies, Inc. ("NEC") and Compaq Computer
Corporation ("Compaq") during the fiscal years ended July 31, 1994, 1995 and
1996 comprised approximately 51%, 52% and 53%, respectively, of the Company's
revenues. Sales of products manufactured by Toshiba accounted for approximately
23%, 25% and 23%, respectively, of the Company's revenues, substantially all of
which sales were of notebook computers and related accessories. Many aspects of
the Company's business are affected by its relationships with major
manufacturers, including product availability, pricing and related terms, and
reseller authorizations. The increasing demand for personal computers and
ancillary equipment has resulted in significant product shortages from time to
time, because manufacturers have been unable to produce sufficient quantities of
certain products to meet demand. There can be no assurance that manufacturers
will maintain an adequate supply of these products to satisfy all the orders of
the Company's customers or that, during periods of increased demand,
manufacturers will provide products to the Company, even if available, or at
discounts previously offered to the Company. In addition, there can be no
assurance that the pricing and related terms offered by major manufacturers will
not adversely change in the future. The failure to obtain an adequate supply of
products, the loss of a major manufacturer, the deterioration of the Company's
relationship with a major manufacturer or the Company's inability in the future
to develop new relationships with other manufacturers could have a material
adverse effect on the Company's business, results of operations and financial
condition. See "Business -- Services and Products."
 
     Certain manufacturers offer market development funds, cooperative
advertising and other promotional programs to systems integrators, distributors
and computer resellers. The Company relies on these funds for many of its
advertising and promotional campaigns. The dollar amounts of funds received by
the Company for the fiscal years ended July 31, 1994, 1995 and 1996 were $1.4
million, $863,000 and $943,000, respectively, representing 1.0%, .5% and .5% of
revenues, respectively. In recent years, manufacturers have generally reduced
their level of support with respect to these programs. The discontinuance or
material reduction of these programs would result in the Company having to spend
its own funds to obtain the same level of advertising and promotion, which could
have a material adverse effect on the Company's business, results of operations
and financial condition. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- General" and "Business -- Sales and
Marketing."
 
INVENTORY MANAGEMENT
 
     The computer industry is characterized by rapid product improvement and
technological change resulting in relatively short product life cycles and rapid
product obsolescence, which can place inventory at considerable valuation risk.
Certain of Manchester's suppliers provide price protection to the Company, which
is intended to reduce the risk of inventory devaluation due to price reductions
on current products. Certain of the Company's suppliers also provide stock
balancing to the Company pursuant to which the Company is able to return unsold
inventory to a supplier as a partial credit against payment for new products.
There are often restrictions on the dollar amount of inventory that can be
returned at any one time. There can be no assurance that such price protection
or stock balancing will be available to the Company in the future, or that these
measures will provide complete protection against the risk of excess or obsolete
inventories. Although the Company maintains a sophisticated proprietary
inventory management system, there can be no assurance that the Company will
continue to successfully manage its existing and future inventory. Failure to
successfully manage its current or future inventory could have a material
adverse effect on the Company's business, results of operations and financial
condition. See "Business -- Management Information Systems."
 
                                        8
<PAGE>   10
 
RAPID TECHNOLOGICAL CHANGE
 
     The markets for the Company's products and services are characterized by
rapidly changing technology and frequent introduction of new hardware and
software products and services, which may render many existing products
noncompetitive, less profitable or obsolete. The Company's continued success
will depend on its ability to keep pace with the technological developments of
new products and services and to address increasingly sophisticated customer
requirements. The Company's success will also depend upon its abilities to
address the technical requirements of its customers arising from new generations
of computer technologies, to obtain these new products from present or future
suppliers and vendors at reasonable costs, to educate and train its employees as
well as its customers with respect to these new products or services and to
integrate effectively and efficiently these new products into both the Company's
internal systems and systems developed for the Company's customers. There can be
no assurance that the Company will be successful in identifying, developing and
marketing product and service developments or enhancements in response to these
technological changes. The failure of the Company to respond effectively to
these technological changes could have a material adverse effect on the
Company's business, results of operations and financial condition.
 
FLUCTUATIONS IN QUARTERLY RESULTS
 
     The Company's quarterly revenues and operating results have varied
significantly in the past and are expected to continue to do so in the future.
Quarterly revenues and operating results generally fluctuate as a result of the
demand for the Company's products and services, the introduction of new hardware
and software technologies with improved features, the introduction of new
services by the Company and its competitors, changes in the level of the
Company's operating expenses, competitive conditions and economic conditions. In
particular, the Company currently is increasing its fixed operating expenses,
including a significant increase in personnel, as part of its strategy to
increase its focus on providing systems integration and other higher margin and
value-added services. Accordingly, the Company believes that period-to-period
comparisons of its operating results should not be relied upon as an indication
of future performance. In addition, the results of any quarterly period are not
indicative of results to be expected for a full fiscal year.
 
CONCENTRATION OF OWNERSHIP AND CONTROL AND ANTI-TAKEOVER PROVISIONS
 
     Based on the number of shares of Common Stock that will be outstanding upon
completion of this offering, Barry R. Steinberg, the Company's Chairman of the
Board, President and Chief Executive Officer, will beneficially own 57.6% of the
outstanding shares of Common Stock (approximately 55.2% if the Underwriters'
over-allotment option is exercised in full). As a result, Mr. Steinberg will
have sufficient voting power to elect all of the Company's directors. Mr.
Steinberg also will be able to veto any proposed sale of the Company, which
under New York law requires the affirmative vote of the holders of two-thirds of
the outstanding shares of Common Stock. See "Principal Shareholders."
 
     The Company's principal shareholders and their families and affiliated
entities own a substantial portion of the real estate leased by the Company. The
Company believes that each of these leases, as amended to be effective with the
closing of this offering, is on terms comparable to those that the Company could
have obtained from independent third parties. However, there can be no assurance
that conflicts of interest may not arise out of such relationships. See
"Principal Shareholders" and "Certain Transactions."
 
     The Company's Certificate of Incorporation provides that up to 5,000,000
shares of Preferred Stock may be issued by the Company from time to time in one
or more series. The Board of Directors is authorized to determine the rights,
preferences, privileges and restrictions granted to and imposed upon any wholly
unissued series of Preferred Stock and to fix the number of shares of any series
of Preferred Stock and the designation of any such series, without any vote or
action by the Company's shareholders. The Board of Directors may authorize and
issue Preferred Stock with voting or conversion rights that could adversely
affect the voting power or other rights of the holders of Common Stock. In
addition, the potential issuance of Preferred Stock may have the effect of
delaying, deferring or preventing a change in control of the Company, may
discourage bids of the Common Stock at a premium over the market price of the
Common Stock and may adversely affect the market price of the Common Stock. In
addition, the Company is subject to Section 912 of the
 
                                        9
<PAGE>   11
 
New York Business Corporation Law which imposes certain restrictions and
requirements on a company's ability to engage in a "business combination" with
an "interested shareholder." See "Description of Capital Stock."
 
DISCRETIONARY USE OF PROCEEDS
 
     Assuming an initial public offering price of $11.00 per share,
approximately $15.8 million of the net proceeds of this offering will be
utilized for general corporate purposes, including working capital. Accordingly,
the Board of Directors will have broad discretion as to the allocation of a
substantial portion of the net proceeds from this offering. See "Use of
Proceeds."
 
SUBSTANTIAL DILUTION
 
     Purchasers of the Common Stock offered hereby will incur an immediate and
substantial dilution of approximately $6.77 per share in net tangible book value
from the assumed $11.00 per share initial public offering price. See "Dilution."
 
NO PRIOR MARKET; STOCK PRICE VOLATILITY
 
     Prior to this offering, there has been no public market for the Company's
Common Stock. Consequently, the initial public offering price will be determined
by negotiations between the Company and the Representative. There can be no
assurance that an active public market for the Common Stock will develop or be
sustained after this offering or that the market price of the Common Stock will
not decline below the initial public offering price. The trading price of the
Common Stock could be subject to wide fluctuations in response to quarter to
quarter variations in operating results, announcements of technological
innovations or new products or services by the Company or its competitors,
general conditions in the industry, changes in earnings estimates by securities
analysts, or other events or factors, many of which are beyond the Company's
control. In addition, the stock market has experienced extreme price and volume
fluctuations, which have particularly affected the market prices of many
technology-related companies and which have often been unrelated to the
operating performance of such companies. The Company's revenue or operating
results in future quarters may be below the expectations of securities analysts
and investors. In such event, the price of the Company's Common Stock would
likely decline, perhaps substantially. These Company-specific factors or broad
market fluctuations may materially adversely affect the market price of the
Company's Common Stock. See "Underwriting."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of substantial amounts of Common Stock in the public market after
this offering or the prospect of such sales could adversely affect the market
price of the Common Stock and the Company's ability to raise capital necessary
to fund its future operations. In addition to the 2,500,000 shares of Common
Stock offered hereby, as of the date of this Prospectus (the "Effective Date"),
there will be approximately 6,200,000 shares of Common Stock outstanding, all of
which are deemed "restricted securities" under Rule 144 under the Securities Act
of 1933, as amended (the "Securities Act"), and may be eligible for sale in the
public market in accordance with certain volume and other restrictions under
Rule 144 under the Securities Act beginning 90 days after the effective date of
this offering. Notwithstanding the ability to resell their shares under Rule
144, the current shareholders have agreed with the Representative not to offer,
sell or otherwise dispose of any shares of Common Stock without the prior
written consent of the Representative for a period of 180 days after the date of
this Prospectus. Sales of a substantial number of shares of Common Stock in the
public market following this offering, pursuant to Rule 144 or otherwise, could
materially adversely affect the market price of the Common Stock. In addition,
the Company intends to register under the Securities Act, following the closing
of this offering, 1,250,000 shares of Common Stock reserved for issuance under
the Company's stock option plan. See "Shares Eligible for Future Sale."
 
                                       10
<PAGE>   12
 
     Upon completion of this offering, the Company has agreed to issue to the
Representative and its designees warrants covering an aggregate of 250,000
shares of Common Stock exercisable for a four-year period commencing one year
from the date of this offering, at an exercise price equal to 120% of the
initial public offering price. The Company has agreed to grant certain demand
and piggyback registration rights to the holders of these warrants. The
existence or exercise of these warrants could materially adversely affect the
Company's ability to raise additional financing at a time when it may be
advantageous to do so. See "Underwriting."
 
ABSENCE OF DIVIDENDS
 
     To date, the Company has not paid any cash dividends and does not presently
intend to pay cash dividends in the foreseeable future. See "Dividend Policy."
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby are estimated to be approximately $24,612,500 ($28,428,125 if the
Underwriters' over-allotment option is exercised in full), assuming an initial
public offering price of $11.00 per share, and deducting underwriting discounts
and commissions and estimated offering expenses. The Company intends to repay
the entire balance outstanding under its line of credit with the net proceeds of
this offering. At July 31, 1996, approximately $6.5 million was outstanding
under the line of credit, of which $3.5 million bore interest at 7.69% per annum
and the balance bore interest at 8.25% per annum. Of the remaining net proceeds,
approximately $1.0 million will be used to relocate or expand the Company's New
York City office, approximately $770,000 will be used to expand training and
sales facilities in Long Island, and approximately $500,000 will be used to
upgrade the Company's internal telecommunications system. The approximately
$15.8 million balance (assuming $6.5 million is outstanding under the line of
credit as of the closing of this offering) will be added to working capital for
general corporate purposes. The retiring of indebtedness under the bank line of
credit will increase the availability of bank credit for general corporate
purposes. Exact allocation of the proceeds for working capital purposes, the
increased funds available under the bank line of credit and the timing of such
expenditures will depend upon various factors, including the availability of
strategic expansion opportunities. Although it is possible that the Company
might acquire businesses complementary to the current or future business of the
Company, the Company's ability to effect such an acquisition will depend upon a
number of factors, including the availability of acquisition candidates or other
business opportunities. The Company has no current plans for any acquisitions,
and no such acquisitions are being negotiated as of the date of this Prospectus.
There can be no assurance that any acquisition will be consummated or that, if
consummated, any acquisition will be successful.
 
     Pending the use of the net proceeds of this offering, the Company will
invest the funds in short-term, interest-bearing, investment-grade securities.
 
                                DIVIDEND POLICY
 
     The Company has never declared or paid any cash dividends on its capital
stock. The Board of Directors currently intends to retain all future earnings,
if any, to fund the growth and development of the Company's business and,
accordingly, does not anticipate paying any cash dividends in the foreseeable
future.

                                    DILUTION
 
     The net tangible book value of the Company at July 31, 1996, was
approximately $12,185,000, or $1.97 per share. Net tangible book value per share
is equal to the Company's total tangible assets less its total liabilities,
divided by the number of shares of Common Stock outstanding. After giving effect
to the sale by the Company of the 2,500,000 shares of Common Stock offered
hereby (at an assumed initial public offering price of $11.00 per share) and the
application of the estimated net proceeds therefrom, the pro forma net tangible
book value of the Company at July 31, 1996, would have been approximately
$36,797,000, or $4.23 per share. This represents an immediate increase in net
tangible book value of $2.26 per share to existing shareholders and an immediate
dilution in net tangible book value of $6.77 per share to purchasers of Common
Stock in this offering, as illustrated in the following table:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis of financial condition and results of
operations of the Company should be read in conjunction with the Consolidated
Financial Statements of the Company and Notes thereto appearing elsewhere in
this Prospectus. The following discussion contains certain forward-looking
statements which involve risks and uncertainties. The Company's actual results
could differ materially from the results anticipated in those forward-looking
statements as a result of certain of the factors set forth in the section of
this Prospectus entitled "Risk Factors" as well as elsewhere herein.
 
GENERAL
 
     Manchester is a systems integrator of computer hardware, software and
networking products, primarily for commercial customers. The Company offers its
customers single-source solutions customized to their information systems needs
by combining value-added services with hardware, software, networking products
and peripherals from leading vendors. To date, most of the Company's revenues
have been derived from product sales.
 
     As a result of intense price competition within the computer industry as
well as other industry conditions, the Company has experienced increasing
pressure on its gross profit and operating margins with respect to the sale of
products. Manchester's strategy includes increasing its focus on providing
value-added services with operating margins that are higher than those obtained
with respect to the sale of products. The Company's future performance will
depend in part on its ability to manage successfully a continuing shift in its
operations towards value-added services.
 
     The Company's largest customer accounted for approximately 14%, 22% and 16%
of the Company's revenues for the fiscal years ended July 31, 1994, 1995 and
1996, respectively, substantially all of which revenues were derived from the
sale of hardware products. There can be no assurance that the Company will
continue to derive substantial revenues from this customer.
 
     The Company's profitability has been enhanced by its ability to obtain
volume discounts from certain manufacturers, which has been dependent, in part,
upon Manchester's ability to sell large quantities of products to computer
resellers, including VARs. There can be no assurance that the Company will be
able to continue to sell products to resellers and thereby obtain the desired
discounts from manufacturers or that the Company will be able to increase sales
to end-users to offset the need to rely upon sales to resellers.
 
     The markets for the Company's products and services are characterized by
rapidly changing technology and frequent introductions of new hardware and
software products and services, which render many existing products
noncompetitive, less profitable or obsolete. The Company believes that its
inventory controls have contributed to its ability to respond effectively to
these technological changes. As of July 31, 1994, 1995 and 1996, inventories
represented 28%, 30% and 24% of total assets, respectively. During these same
fiscal years, the Company's average inventory turnover was 17, 16 and 18 times,
respectively. The failure of the Company to anticipate technology trends or to
continue to effectively manage its inventory could have a material adverse
effect on the Company's business, results of operations and financial condition.
 
     The Company believes its controls on accounts receivable have contributed
to its profitability. The Company's bad debt expense represented .3%, .1% and
 .1% of total revenues for the years ended July 31, 1994, 1995 and 1996,
respectively.
 
     The Company's quarterly revenues and operating results have varied
significantly in the past and are expected to continue to do so in the future.
Quarterly revenues and operating results generally fluctuate as a result of the
demand for the Company's products and services, the introduction of new hardware
and software technologies with improved features, the introduction of new
services by the Company and its competitors, changes in the level of the
Company's operating expenses, competitive conditions and economic conditions. In
particular, the Company currently is increasing its fixed operating expenses,
including a significant increase in personnel, as part of its strategy to
increase its focus on providing higher margin, value-added services.
Accordingly, the Company believes that period-to-period comparisons of its
operating results should not be
 
                                       15
<PAGE>   17
relied upon as an indication of future performance. In addition, the results of
any quarterly period are not indicative of results to be expected for a full
fiscal year.
 
RESULTS OF OPERATIONS
 
     The following table sets forth, for the periods indicated, information
derived from the Company's Consolidated Statements of Income expressed as a
percentage of revenues. The percentages in the table, as well as the amounts and
percentages in the discussions presented below, are presented assuming the
reduction in (i) officers' compensation to amounts stipulated in agreements with
the Company's Chief Executive Officer and Executive Vice President without any
diminished duties or responsibilities, (ii) compensation from that paid to the
former Chief Financial Officer during each of the years in the three-year period
ended July 31, 1996 to the annual compensation currently payable to the present
Chief Financial Officer, and (iii) rent paid to related parties to amounts
stipulated in current leases for the respective portions of the five-year period
ended July 31, 1996 during which these leases (or their predecessors) were in
effect. See "Management," "Certain Transactions" and Note 12 of the Consolidated
Financial Statements.

YEAR ENDED JULY 31, 1996 COMPARED TO YEAR ENDED JULY 31, 1995
 
     Revenues.  The Company's revenues increased $18.8 million or 11.0% from
$170.8 million in fiscal 1995 to $189.7 million in fiscal 1996 due to increased
revenues from both new and existing customers. Many factors contributed to this
increase, including new product introductions, special product purchases and
volume and price changes with no one factor having any material effect on this
increase.
 
     Gross Profit.  Cost of revenues includes the direct costs of products sold,
freight and the personnel costs associated with providing technical services,
offset in part by manufacturers' market development funds. All other operating
costs are included in selling, general and administrative expenses. Gross profit
increased $2.1 million or 8.2% from $24.9 million in fiscal 1995 to $27.0
million in fiscal 1996 primarily as a result of the increase in revenues. Gross
profit as a percentage of revenues decreased from 14.6% to 14.2%. The decrease
in the gross profit percentage was due to changes in product mix as well as
increased pricing pressures prevalent within the industry. Competitive
pressures, changes in the types of products or services sold and product
availability result in fluctuations in gross profit from period to period.
 
     Pro Forma Selling, General and Administrative Expenses.  Pro forma selling,
general and administrative expenses increased $1.8 million or 9.8% from $18.2
million in fiscal 1995 to $20.0 million in fiscal 1996. Approximately $917,000
of this increase related to higher payroll and related costs due primarily to
the hiring of additional technical and administrative staff in support of the
Company's strategy to increase its value-added services revenue. Rent and
occupancy costs also increased by approximately $197,000 due primarily to
 
                                       16
<PAGE>   18
 
the leasing of an additional facility to meet the Company's current and future
needs. In addition, commissions paid to the Company's sales force increased
approximately $328,000 due to the increase in revenues in fiscal 1996.
 
     Interest Expense, Net.  Interest expense, net increased from $346,000 in
fiscal 1995 to $374,000 in fiscal 1996 primarily due to increased borrowings.
 
     Pro Forma Provision for Income Taxes.  The pro forma effective income tax
rate for fiscal 1995 and 1996 remained relatively constant at approximately 40%.
 
YEAR ENDED JULY 31, 1995 COMPARED TO YEAR ENDED JULY 31, 1994
 
     Revenues.  Revenues increased $33.5 million or 24.4% from $137.4 million in
fiscal 1994 to $170.8 million in fiscal 1995. This increase was due primarily to
the increased demand for pentium-based personal computers and notebook computers
and increased sales to the Company's largest customer.
 
     Gross Profit.  Gross profit increased $4.3 million or 20.6% from $20.7
million in fiscal 1994 to $24.9 million in fiscal 1995 principally as a result
of increased revenues. Gross profit as a percentage of revenues decreased from
15.1% in fiscal 1994 to 14.6% in fiscal 1995 as a result of changes in the mix
of products sold by the Company during the periods and increasing pricing
pressures prevalent in the industry.
 
     Pro Forma Selling, General and Administrative Expenses.  Pro forma selling,
general and administrative expenses increased $633,000 or 3.6% from $17.5
million in fiscal 1994 to $18.2 million in fiscal 1995. Such costs declined as a
percentage of revenues from 12.8% to 10.7% as a result of the 24.4% increase in
revenues and the relatively small increase in pro forma selling, general and
administrative expenses. The dollar increase was principally due to higher sales
commissions due to the increase in revenues in fiscal 1995 as well as higher
payroll and related costs partially offset by lower bad debt expense.
 
     Interest Expense, Net.  Interest expense, net increased from $236,000 in
fiscal 1994 to $346,000 in fiscal 1995, principally due to increased borrowings.
 
     Pro Forma Provision for Income Taxes.  The pro forma effective income tax
rate decreased from 42% in fiscal 1994 to 40% in fiscal 1995. This decrease was
primarily due to lower state income taxes in fiscal 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's primary sources of financing have been the internally
generated working capital from profitable operations and a line of credit from a
financial institution.
 
     For the year ended July 31, 1996, cash provided by operations increased to
$4.2 million as compared to cash provided by operations of $1.6 million in
fiscal 1995 and cash used in operations of $4.1 million in fiscal 1994. The
increase in cash provided by operations in fiscal 1996 as compared to fiscal
1995 was primarily due to higher net income and reduced inventory levels. The
increase in cash provided by operations in fiscal 1995 as compared to fiscal
1994 was primarily due to increased balances in accounts payable and accrued
expenses. The Company's accounts receivable and accounts payable and accrued
expenses balances as well as its investment in inventory can fluctuate
significantly from one year end to the next due to the receipt of large customer
orders or payments or variations in product availability and vendor shipping
patterns at any particular date. Generally, the Company's experience is that
increases in accounts receivable, inventory and accounts payable and accrued
expenses will coincide with growth in revenue and increased operating levels.
 
     Cash used in investing activities increased from approximately $448,000 in
fiscal 1994 and $440,000 in fiscal 1995 to $1.0 million in fiscal 1996. In
addition, during fiscal 1996, the Company acquired $305,000 of computer
equipment through a capital lease obligation resulting in total fixed asset
additions for fiscal 1996 of $1.3 million. This increased level of spending
reflects the initial expenditures related to the Company's plans to expand its
operations and facilities to accommodate current and anticipated increases in
revenues.
 
     Cash provided by financing activities in fiscal 1996 was approximately
$751,000 compared to $200,000 in fiscal 1995 and $3.2 million in fiscal 1994.
The change in cash provided by financing activities is primarily
 
                                       17
<PAGE>   19
 
reflective of increases in borrowing by the Company under its line of credit
with a financial institution. Similar to the items discussed above, the
Company's level of borrowing will fluctuate significantly in order to provide
cash for operations and capital expenditures.
 
     The Company's line of credit agreement with a financial institution
provides for a maximum of $9.5 million of borrowings and is due on demand.
Interest on borrowings is computed at the Company's option based on the
financial institution's prime rate (8.25% at July 31, 1996) or at LIBOR plus 2%
(7.69% at July 31, 1996). The line provides for a general security interest
first lien on all of the Company's assets, to the extent a first lien is
available. The line is guaranteed by Barry M. Steinberg, the Company's
President, Chief Executive Officer and majority shareholder. At July 31, 1996,
borrowings of $6.5 million were outstanding under the line of credit. A portion
of the net proceeds of this offering will be applied to repay the outstanding
indebtedness under the line. Following this offering, the Company expects to
maintain the line, may utilize it to fund operations and intends to eliminate
Mr. Steinberg's guarantee.
 
     The Company believes that the net proceeds of this offering together with
current working capital, expected cash flows from operations and available
borrowings under the line of credit will be adequate to support current
operating levels for the foreseeable future, specifically through at least the
end of fiscal 1998. The Company currently has no major commitments for capital
expenditures. Future capital requirements of the Company include those for the
growth of working capital items such as accounts receivable and inventory and
the purchase of equipment and expansion of facilities as well as the possible
opening of new offices. The Company's ability to implement its expansion
strategy is dependent upon its ability to generate sufficient cash flow to meet
its obligations on a timely basis and to obtain additional funds through equity
or debt financings or from other sources, as may be required.
 
INFLATION
 
     The Company does not believe that inflation has had a material effect on
the Company's operations.
 
NEW ACCOUNTING STANDARD
 
     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("Statement 123"). Statement 123 establishes financial accounting
and reporting standards for stock-based compensation plans. Statement 123 also
applies to transactions in which an entity issues its equity instruments to
acquire goods or services from nonemployees. Statement 123 encourages a fair
value based method of accounting for employee stock options or other similar
equity instruments. Entities electing not to adopt a fair value method must make
pro forma disclosures of net income and earnings per share as if a fair value
based method had been applied. Statement 123 is effective for fiscal year 1997.
The Company has elected not to adopt a fair value based accounting method for
employee stock options and therefore does not expect that the adoption of
Statement 123 will have a material impact on its financial position or results
of operations. The Company will disclose, commencing in fiscal 1997, the pro
forma net income and earnings per share as if such method had been used to
account for stock-based compensation cost.

                                    BUSINESS
 
GENERAL
 
     Manchester Equipment Co., Inc. is a systems integrator of computer
hardware, software and networking products, primarily for commercial customers.
The Company offers its customers single-source solutions customized to their
information systems needs by combining value-added services with hardware,
software, networking products and peripherals from leading vendors. Over the
past 20 years, the Company has forged long-standing relationships with both
customers and suppliers and capitalized on the rapid developments in the
computer industry, including the shift toward client/server-based platforms.
Each year during this period, the Company has been profitable and has generated
growth in revenues.
 
     Manchester's marketing focus is on mid- to large-sized companies, which
have become increasingly dependent upon complex information systems in an effort
to gain competitive advantages. While many of these companies have the financial
resources to make the required capital investments in information systems, often
they do not have the necessary information technology personnel to design,
install or maintain complex systems or to incorporate the continuously evolving
technologies. As a result, these companies are turning to independent third
parties to procure, design, install, maintain and upgrade their information
systems.
 
     The Company offers its customers a variety of value-added services, such as
consulting, integration and support services, together with a broad range of
computer and networking products from leading vendors. Consulting and
integration services include systems design, performance analysis, security
analysis, migration planning, product procurement, configuration, testing and
systems installation and implementation. Support services include network
management, "help-desk" support, and enhancement, maintenance and repair of
computer systems. The Company's customers include Barnes & Noble Inc., Cabletron
Systems Inc., Conde Nast Publications Inc., J&R Music World, National
Broadcasting Company Inc., Pfizer Inc., Reuters America Inc., Sotheby's Inc.,
Time Warner Inc., The Toronto Dominion Bank, United Parcel Service of America
Inc. and the United States Merchant Marine Academy. The Company offers these
services and products from its headquarters in Long Island, New York, and its
regional offices in New York City, Needham, Massachusetts and Boca Raton and
Tampa, Florida.
 
     The Company was incorporated in New York in 1973 and has one active
wholly-owned subsidiary, Manchester International, Ltd., a New York corporation
which sells computer hardware, software and networking products to resellers
domestically and internationally.
 
INDUSTRY
 
     Businesses have become increasingly dependent upon complex information
systems in an effort to gain competitive advantages or to maintain competitive
positions. Computer technology and related products are continuously evolving,
making predecessor technologies or products obsolete within a few years or, in
some cases, within months. The constant changes in hardware and software and the
competitive pressure to upgrade existing products create significant challenges
to companies.
 
     Over the last several years, the increase in performance of personal
computers, the development of a variety of effective business productivity
software programs and the ability to interconnect personal computers in high
speed networks have led to an industry shift away from mainframe computer
systems to client/server systems based on personal computer technology. In such
systems, the client computer, in addition to its stand-alone capabilities, is
able to obtain resources from a central server or servers. Accordingly, personal
computers may share everything from data files to printers. Recently, networked
applications such as electronic mail and work group productivity software,
coupled with widespread acceptance of Internet technologies, have led companies
to implement corporate intranets (networks that enable end-users (e.g.,
employees) to share information). The use of a corporate intranet allows a
company to warehouse valuable information, which may be "mined" or accessed by
employees or other authorized users through readily available Internet tools
such as Web browsers and other graphical user interfaces.
 
                                       19
<PAGE>   21
 
     With these advances in information systems and networking, many companies
are reengineering their businesses using these technologies to enhance their
revenues and productivity. However, as the design of information systems has
become more complex to accommodate the proliferating network applications, the
configuration, selection and integration of the necessary hardware and software
products have become increasingly more difficult and complicated. While many
companies have the financial resources to make the required capital investments,
they often do not have the necessary information technology personnel to design,
install or maintain complex systems and may not be able to provide appropriate
or sufficient funding or internal management for the maintenance of their
information systems. As a result, such companies are increasingly turning to
independent third parties to procure, design, install, maintain and upgrade
their information systems. By utilizing the services of such third parties,
companies are able to acquire state-of-the-art equipment and expertise on a
cost-effective basis.
 
THE MANCHESTER SOLUTION
 
     Manchester offers its customers single-source solutions customized to their
information systems needs. The Manchester solution includes a variety of
value-added services, including consulting, integration, network management,
"help-desk" support, and enhancement, maintenance and repair of computer
systems, together with a broad range of computer and networking products from
leading vendors. Manchester believes it provides state-of-the-art,
cost-effective information systems designed to meet its customers' particular
needs.
 
     As a result of the Company's long-standing relationships with certain
suppliers and its large volume purchases, the Company is often able to obtain
significant purchase discounts which can result in cost-savings for its
customers. Manchester's relationships with its suppliers, its inventory
management system and industry knowledge generally enable it to procure desired
products on a timely basis and therefore to offer its customers timely product
delivery.
 
STRATEGY
 
     The key elements of the Company's strategy include:
 
     EMPHASIZING VALUE-ADDED SERVICES.  Value-added services, such as
consulting, integration and support services, generally provide higher profit
margins than computer hardware sales. The Company intends to increase its focus
on providing these services through a number of key strategies. The Company
plans to recruit additional technical personnel with broad-based knowledge in
systems design and specialized knowledge in different areas of systems
integration, including application software, inter-networking (including
bridges, routers and switches), database design and management and security. The
Company plans to actively promote the benefits of corporate intranets and
intends to introduce additional services, including remote network management
services and fee-based "help desk" services. The remote network management
system is expected to consist of dedicated servers and software located at the
Company's Long Island headquarters. This system is intended to allow the
Company's specially trained engineers to solve their customers' network systems
problems from the Company's facilities. The fee-based "help desk" services are
anticipated to be available for end-users, regardless of whether they purchase
products or other services from the Company.
 
     INCREASING MARKETING FOCUS ON COMPANIES OUTSIDE THE FORTUNE
500.  Manchester has decided to increase its marketing focus on those companies
outside the Fortune 500 in order to increase its value-added services revenue.
Manchester's experience is that these companies are increasingly looking to
third parties to provide a complete solution to their information systems needs
from both a service and product standpoint. These companies often do not have
the necessary information technology personnel to procure, design, install or
maintain complex systems or to incorporate continuously evolving technologies.
Manchester believes that it can provide these companies with solutions to their
information systems requirements by providing a variety of value-added services
together with a broad range of computer and networking products.
 
     INTRODUCING AN ELECTRONIC ORDERING SYSTEM.  Manchester is in the process of
implementing an electronic ordering system. This ordering system will enable
customers to access the Company via the Internet, review
 
                                       20
<PAGE>   22
 
various products, systems and services offered by the Company and place their
orders on-line. Customers will also be able to obtain immediate customized
information regarding products, systems and services that meet their specific
requirements. The ordering system will produce a matrix of alternative fully
compatible packages, together with their availability and related costs, based
on parameters indicated by the customer. Customers will not be granted access to
this system without prior credit clearance.
 
     INCREASING SALES FORCE PRODUCTIVITY.  Manchester is addressing a variety of
strategies to increase sales force productivity. The Company is in the process
of implementing an electronic sales information system utilizing similar
technology to the electronic ordering system described above. The electronic
sales information system will allow the Company's sales representatives to
obtain immediate customized information regarding products and services that
meet the specific system requirements of customers and the availability and
related costs of such products and services. The Company believes that this
system will increase the productivity of its sales representatives by enabling
them to offer rapid and comprehensive solutions to their customers' needs while
reducing the possibility of returns based on incompatible products.
 
     Manchester also is upgrading its internal telecommunications system.
Through its enhanced system, anticipated to be implemented during the first
calendar quarter of 1997, telephone calls can be automatically placed to a
targeted list of existing or potential customers and, upon connection, will be
routed automatically to available sales representatives with on-screen
information containing product and service data for current customers and market
demographic data for potential customers. The system also will have the
capability to route automatically in-coming calls to available sales
representatives in response to a caller's answers to automated queries.
 
     The Company also intends to provide increased training of its sales
representatives in matters relating to value-added services, such as consulting
and integration services. To facilitate such training, the Company plans to
construct a dedicated training facility to be located in one of its existing
offices in Long Island.
 
     EXPANDING NEW YORK METROPOLITAN AREA PRESENCE.  The Company believes that
it has a strong presence and wide name recognition in the New York Metropolitan
area, where there is a growing corporate demand for computer products and
services. Manchester is seeking to expand its presence in this area by enlarging
its New York City office and increasing the sales and service capabilities of
such office, and expanding its sales, service and training capabilities at its
Long Island headquarters. The Company believes that these steps will enable it
to capture a greater percentage of the New York Metropolitan area market.
 
     EXPANDING INTO ADDITIONAL BUSINESS CENTERS.  The Company has regional
offices in Needham, Massachusetts and Boca Raton and Tampa, Florida, from which
it derived approximately 10% of its revenues for the fiscal year ended July 31,
1996. The Company intends to continue to expand geographically into growing
business centers in the eastern half of the United States. It is anticipated
that each office would have the capability to perform a broad array of services
as well as engage in product sales.
 
SERVICES AND PRODUCTS
 
     The Company offers customized single-source solutions to its customers'
information systems requirements, including consulting, integration and support
services, together with a broad range of computer and networking products from a
variety of leading vendors. The Company provides its services through a skilled
staff of engineers who are trained and certified in leading products and
technology, including Microsoft Windows NT, Novell NetWare and Cisco Systems
routers and switches.
 
     SERVICES.  The Company's services include consulting, integration and
support services.
 
        CONSULTING.  The Company's staff of senior systems engineers provides
consulting services consisting of systems design, performance and security
analysis and migration planning services.
 
         Systems design services include network, communications, applications
and custom solutions design. Network design services involve analysis of a
customer's overall network needs, including access to the Internet;
communications design services involve analysis and creation of enterprise-wide
networks, including corporate intranets; applications design services include
creation of relational databases meeting customers'
 
                                       21
<PAGE>   23
 
specific business requirements; and custom solutions design services include
design of storage systems, remote access systems and document retention through
scanning technology.
 
         Performance analysis involves analyzing a customer's information
systems to assess potential points of failure, to determine where performance
could be increased and to prepare for change and growth. This service includes
the evaluation of applications and their interaction with the network in order
to maximize existing computer resources. Through this evaluation process, which
includes a detailed report to the end-user, a plan for the optimization of the
customer's existing system is created, as well as recommendations for
enhancements and future systems.
 
         Security analysis involves working with customers to develop security
policies covering network and data security, as well as risk analysis. After a
policy is developed, a security strategy is planned and deployed using a variety
of tools, including physical firewalls, packet filtering, encryption and user
authentication.
 
         Migration planning involves the performance of a detailed assessment of
existing mission critical systems, followed by an analysis of the end-user's
future requirements. Working closely with the customer, Manchester's consultants
develop a migration strategy using a defined project plan that encompasses
skills transfer and training, checking for data integrity, project management
and consolidation and reallocation of resources. The primary objective of this
service is to rapidly move the customer from a slow or expensive system to a
newer, more efficient and cost-effective solution.
 
        INTEGRATION.  Integration services include product procurement,
configuration, testing, installation and implementation.
 
         The Company maintains a sophisticated systems build and test area,
adjacent to its warehousing facilities, where computer systems are configured
and tested through the use of automated systems. Manchester manages the
installation and implementation of its customers' information systems, and
provides critical path analysis, vendor management and facility management
services. Critical path analysis involves the management and coordination of the
various hardware and software networking components of a systems design project.
The Company's engineers prepare reports setting forth coordinated timetables
with respect to installing and integrating the customer's information systems.
Vendor management includes interfacing with the suppliers of computer products
in installing a project; facility management involves management of the labor
aspects of a project, including supervision of electricians and other tradesmen.
 
        SUPPORT.  The Company offers support services for its customers'
existing information systems, including network management, "help-desk"
services, and enhancement, maintenance and repair.
 
         Network management consists of managing the compatibility of, and
communication between, the various components comprising a customer's
information system. The increased expense associated with the ownership of
information systems has encouraged customers to outsource the management of
computer networks, including local area networks ("LANs") and wide area networks
("WANs"). Currently, the Company's engineers provide network management services
on site at customers' facilities. The Company plans to expand these services by
enabling its specially trained engineers to solve many of their customers'
network systems problems on a remote basis from the Company's facilities.
 
         "Help-desk" services consist of providing customers with telephone
support. The Company is in the process of expanding its "help-desk" capabilities
and intends to develop a fee-based "help-desk." In addition, the Company's
service call management system, which the Company is in the process of
enhancing, will enable the Company's "help-desk" technicians to access an
archive of prior service calls concerning similar problems and their solutions,
resulting in a more efficient response to customers' calls.
 
         Enhancement, maintenance and repair services range from broad on-site
coverage to less expensive, basic maintenance and repair of itemized hardware or
software, as well as enhancements such as upgrades of existing systems. Field
representatives are equipped with notebook computers to facilitate the exchange
of information with both the information systems at the Company's headquarters
and with technical databases available on the Internet. The Company maintains a
laboratory at its Long Island facilities where the Company prototypes customer
problems for quicker solutions without jeopardizing customers' information
systems.

</TABLE>
 
     For the fiscal years ended July 31, 1994, 1995 and 1996, sales by the
Company of products manufactured by Toshiba, Hewlett-Packard, NEC and Compaq
collectively comprised approximately 51%, 52% and 53%, respectively, of the
Company's revenues. In these fiscal years, sales of products manufactured by
Toshiba accounted for approximately 23%, 25% and 23%, respectively, of the
Company's revenues, substantially all of which were sales of notebook computers
and related accessories. The total dollar volume of products purchased directly
from manufacturers, as opposed to distributors or resellers, was approximately
$96 million, $124 million and $130 million for the fiscal years ended July 31,
1994, 1995 and 1996, respectively, and as a percentage of total cost of products
sold was approximately 83%, 86% and 81%, respectively.
 
     The Company seeks to obtain volume discounts for large customer orders
directly from manufacturers and through aggregators and distributors.
 
CUSTOMERS
 
     The Company believes that it benefits from its long-standing relationships
with many of its customers, providing opportunities for continued sales and
services. Manchester believes that its broad range of capabilities with respect
to both products and services is attractive to companies of all sizes. Although
Manchester is planning to target companies outside the Fortune 500 as one part
of its strategy, it has sold, and anticipates that it will continue to sell, to
some of the largest companies in the United States. For the fiscal years ended
July 31, 1994, 1995 and 1996, approximately 14%, 22% and 16% of the Company's
total revenues, respectively, were derived from United Parcel Service of
America, Inc. Some of the Company's other commercial customers include Barnes &
Noble Inc., Cabletron Systems Inc., Cablevision Systems Corp., Conde Nast
Publications Inc., J&R Music World, National Broadcasting Company Inc., Pfizer
Inc., Reuters America Inc., SONY Theaters, Sotheby's Inc., Time Warner Inc., The
Toronto Dominion Bank, United Nations International Children's Emergency Fund
and the United States Merchant Marine Academy.

     The Company's return policy generally allows customers to return hardware
and unopened software, without restocking charges, within 30 days of the
original invoice date, subject to advance approval and certain other conditions.
 
     The Company grants credit to customers meeting specified criteria and
maintains a centralized credit department that reviews credit applications.
Accounts are regularly monitored for collectibility and appropriate action is
taken upon indication of risk.
 
SALES AND MARKETING
 
     The Company's sales are generated primarily by its 59 person sales force.
These sales representatives generally are responsible for meeting all of their
customers' product and service needs and are supervised by sales managers with
significant industry experience. The sales managers are responsible for
overseeing sales representative training, establishing sales objectives and
monitoring account management principles and procedures. Sales representatives
attend seminars conducted by manufacturers' representatives at the Company's
facilities, at which the Company's new and existing product and service
offerings are discussed.
 
     The Company's sales representatives are assisted by technical personnel who
support and supplement the sales efforts. The responsibilities of technical
support personnel include answering preliminary inquiries from customers
regarding systems design, and on-site visits to customers' facilities. At
customers' facilities, the technical personnel gather information necessary to
assist customers in making informed decisions regarding their information
systems. Such data include the nature of the customer's current information
systems, the existing hardware and networking environment, the customer's level
of expertise and its applications needs.
 
     Manchester believes that its name is widely recognized for high quality,
competitively priced products and services. The Company promotes name
recognition and the sale of its products and services through regional business
directories, trade magazine advertisements, radio advertisements, direct
mailings to customers and participation in computer trade shows and special
events. The Company advertises at numerous sporting events in the New York
metropolitan region, including full page four-color advertisements in yearbooks
and/or program guides for sports teams such as the New York Mets, the New York
Knicks and the New York Rangers, and has advertised on New York Mets and New
York Yankees tickets. The Company also promotes interest in its products and
services through its website on the Internet, and intends to expand its website
information to provide an electronic catalog of its products and services.
Several manufacturers offer market development funds, cooperative advertising
and other promotional programs, on which the Company relies for many of its
advertising and promotional campaigns. See "Risk Factors -- Dependence on Major
Manufacturers."
 
     Sales force training is an integral part of the Company's strategy to
increase its focus on providing value-added services. As client/server-based
systems, applications and network capabilities grow in complexity, the need for
technically knowledgeable sales personnel becomes critical to the sale of
value-added services. Accordingly, the Company anticipates expanding its
training capabilities at one of its Long Island facilities to conduct seminars
for sales representatives. The seminars will address such topics as general
developments in the computer industry, systems integration services and the
Company's management information systems. The Company intends to utilize its
technical personnel to conduct such seminars and may hire additional dedicated
trainers as needed.
 
MANAGEMENT INFORMATION SYSTEMS
 
     The Company currently uses an IBM AS/400 integrated management information
system, which is a real-time, on-line system enabling instantaneous access and
processing. The Company maintains a proprietary inventory management system on
its computer system pursuant to which product purchases and sales are
continually tracked and analyzed. The Company's computer system is also used for
accounting, billing and invoicing.
 
     The Company's information system assists management in maintaining controls
over the Company's inventory and receivables. Manchester's average inventory
turnover was 17, 16 and 18 times for the fiscal years
 
                                       24
<PAGE>   26
 
ended July 31, 1994, 1995 and 1996, respectively, and Manchester experienced bad
debt expense of less than .3% of revenues in each of these years.
 
     During the fiscal year ended July 31, 1996, the Company invested in its
management information systems, including upgrading and expanding the IBM AS/400
system, implementing a client/server-based management system to track services
rendered for customers, and upgrading servers and network infrastructures for
its headquarters. The Company utilizes experienced in-house technical personnel,
assisted by the Company's senior engineers, to upgrade and integrate additional
functions into the Company's management information systems.
 
COMPETITION
 
     The computer industry is characterized by intense competition. The Company
directly competes with local, regional and national systems integrators,
value-added resellers and distributors as well as with certain computer
manufacturers that market through direct sales forces. While the Company's
competitors vary depending upon the particular market, some of the national and
regional competitors of the Company include AmeriData Technologies, Inc.,
CompuCom Systems, Inc., Dataflex Corporation, Entex Information Services, Inc.,
Vanstar Corporation and Electronic Data Systems Corporation. The computer
industry has recently experienced a significant amount of consolidation through
mergers and acquisitions, and manufacturers of personal computers may increase
competition by offering a range of services in addition to their current product
and service offerings. In the future, the Company may face further competition
from new market entrants and possible alliances between existing competitors.
Some of the Company's competitors have, or may have, greater financial,
marketing and other resources, and may offer a broader range of products and
services, than the Company. As a result, they may be able to respond more
quickly to new or emerging technologies or changes in customer requirements,
benefit from greater purchasing economies, offer more aggressive hardware and
service pricing or devote greater resources to the promotion of their products
and services.
 
     The Company's ability to compete successfully depends on a number of
factors such as breadth of product and service offerings, sales and marketing
efforts, product and service pricing, and quality and reliability of services.
 
EMPLOYEES
 
     At August 31, 1996, the Company had 222 full-time employees consisting of
23 sales representatives, 26 management personnel, 50 technical personnel and
123 distribution and clerical personnel. In addition, at August 31, 1996, the
Company had 36 independent sales representatives. The Company is not a party to
any collective bargaining agreements and believes its relations with its
employees are good.
 
INTELLECTUAL PROPERTY
 
     The Company owns one federally registered service mark with respect to its
name and logo. Most of the Company's various dealer agreements permit the
Company to refer to itself as an "authorized dealer" of the products of those
manufacturers and to use their trademarks and trade names for marketing
purposes. The Company considers the use of these trademarks and trade names in
its marketing to be important to its business.
 
PROPERTIES
 
     The Company's main offices and warehouses are located in four buildings in
Hauppauge, New York, consisting of approximately 40,000 and 60,000 square feet
of office and warehouse space, respectively, under leases expiring between
January 1998 and October 2005, for aggregate annual lease payments of
approximately $1,040,000 in fiscal 1996. Three of these buildings are leased
from entities controlled by, or affiliated with, certain of the Company's
executive officers and principal shareholders. Effective with the closing of
this offering, the leases with related parties have been amended to provide
terms comparable to those that could be obtained from independent third parties.
Giving effect to these amended leases, the aggregate annual lease
 
                                       25
<PAGE>   27
 
payments for all four buildings in Hauppauge, New York will be approximately
$778,000 in fiscal 1997. The Company leases an additional office in Massapequa,
Long Island for $10,572 per annum on a month-to-month basis from an entity of
which Messrs. Rothlein and Bivona own 25% and 50%, respectively. See "Certain
Transactions." The Company leases additional offices in New York City, Needham,
Massachusetts and Boca Raton and Tampa, Florida, under leases expiring in
January 1999, April 1997, July 1998 and December 1996, respectively, for
aggregate rental payments of approximately $146,000 and $148,000 in fiscal 1996
and fiscal 1997, respectively, with options to renew in Needham and Tampa. The
Company believes that its Hauppauge and regional offices and warehouse space are
well maintained and are adequate for present requirements. The Company intends
to relocate or expand its New York City office as part of its strategy. See
"Strategy -- Expanding New York Metropolitan Area Presence."

STOCK OPTION PLAN
 
     Under the Company's 1996 Incentive and Non-Incentive Stock Option Plan (the
"Plan"), which was approved by the Company's shareholders in October 1996, an
aggregate of 1,250,000 shares of Common Stock are reserved for issuance upon
exercise of options thereunder. The Plan will be administered by the
Compensation Committee of the Board of Directors (the "Committee"). Under the
Plan, incentive stock options, as defined in section 422 of the Internal Revenue
Code of 1986, as amended, may be granted to employees, and non-incentive stock
options may be granted to employees, directors and such other persons as the
Committee may determine. The Committee will also determine (i) the exercise
price of each option which must be equal to at least 100% (with respect to
incentive stock options) and at least 85% (with respect to non-incentive stock
options) of the fair market value of the Common Stock on the date of grant, (ii)
the number of shares of Common Stock subject to each option, (iii) the term of
each stock option up to a maximum of 10 years (or, in the case of incentive
options, five years for certain employees) and (iv) the time or times when the
stock option becomes exercisable. Incentive stock options expire three months
from the date of the holder's termination of employment with the Company other
than by reason of death or disability, in which event the option may be
exercised during the 12-month period following the date of termination of
employment to the extent such option was exercisable on the date of termination
of employment but in no event beyond the term of such option. The maximum number
of shares of Common Stock underlying options which may be granted to any person
in any calendar year is 200,000. Options may be exercised in cash, Common Stock,
or any combination thereof. No options have been granted to date under the Plan.
 
     In the event of a Change in Control (as defined below), all outstanding
options under the Plan shall accelerate and become immediately fully
exercisable. Under the Plan, a Change in Control means (i) the sale or other
disposition to a person, entity or group of 50% or more of the Company's
consolidated assets, (ii) the acquisition of 50% or more of the outstanding
shares by a person or group or (iii) if the majority of the Company's Board of
Directors consists of persons other than the Continuing Directors (as defined
below). The term "Continuing Director" shall mean any member of the Company's
Board of Directors on the effective date of the Plan and any other member of the
Board of Directors who shall be recommended or elected to succeed or become a
Continuing Director by a majority of the Continuing Directors who are then
members of the Board of Directors.

     Until August 1994, the Company was affiliated with Electrograph Systems,
Inc. ("Electrograph"), a value-added distributor of microcomputer peripherals,

Company paid approximately $322,000 and $385,000, respectively, to Electrograph
for the purchase of products. In August 1994, Bitwise Designs, Inc. ("Bitwise"),
a publicly-traded company engaged in the manufacture and distribution of
document imaging systems, personal and industrial computers and related
peripherals, acquired Electrograph through a stock-for-stock merger; Mr.
Steinberg acquired beneficial ownership of less than 1% of the outstanding
capital stock of Bitwise for the common stock of Electrograph in which he had a

and provided consulting services to, Bitwise from August 1994 through September
17, 1996.

of $399,000, $417,000 and $435,000, respectively, to such entity. Effective with
the closing of this offering, the leases with the affiliated parties with
respect to the leases of the Hauppauge, New York facilities have been amended to
provide terms comparable to those that could be obtained from independent third
parties. Giving effect to these amended leases, the rent for the properties
located at 40 Marcus Boulevard, 160 Oser Boulevard and 50 Marcus Boulevard will
be $170,375, $255,000 and $324,225, respectively, for fiscal 1997. The Company
leases an additional office in Massapequa, New York at $10,572 per annum on a
month-to-month basis from an entity of which Messrs. Rothlein and Bivona own 25%
and 50%, respectively. See "Business -- Properties."
 
     Mr. Steinberg personally guarantees the Company's obligations under its
bank line of credit for which he receives no compensation. Following this
offering, the Company intends to eliminate Mr. Steinberg's guarantee. See Note 7
of Notes to Consolidated Financial Statements.
 
     On May 7, 1996, following his retirement as the Company's Chief Financial
Officer which became effective June 30, 1996, Mr. Bivona elected, under an
agreement with the Company, to require the Company to purchase 62,626 shares of
Common Stock held by him for $471,000 payable in four equal quarterly
installments, without interest, commencing May 7, 1996. In September 1996, Mr.
Bivona agreed with the Company to terminate transfer restrictions previously
applicable to the balance of the shares of Common Stock owned by Mr. Bivona. In
connection therewith, Mr. Bivona terminated certain put rights he had with
respect to such shares, agreed to the 180-day lock-up required by the
Representative of the Underwriters and agreed to the volume and manner of sale
limitations applicable to an affiliate under Rule 144 under the Securities Act
with respect to the resale of shares of Common Stock owned by him. Pursuant to
the agreement, Mr. Bivona has certain piggyback registration rights in the event
of a subsequent registration of Common Stock in which Mr. Steinberg is a selling
shareholder. See "Shares Eligible For Future Sale."
 
     Joel Rothlein, Esq., a director of the Company, is a partner of Kressel,
Rothlein & Roth, Esqs., which, with its predecessor firms, has acted as outside
general counsel to the Company since the Company's inception. Kressel, Rothlein
& Roth, Esqs. was paid $50,000 from the Company for legal services rendered to
the Company in the fiscal year ended July 31, 1996 and anticipates receiving
fees of approximately $350,000 from the Company for services to be rendered to
the Company in the fiscal year ending July 31, 1997.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this offering, the Company will have 8,700,000 shares of
Common Stock outstanding. Of these shares, the 2,500,000 shares sold in this
offering will be freely tradeable without restriction or further registration
under the Securities Act, except that any shares purchased by "affiliates" of
the Company, as that term is defined in Rule 144 ("Rule 144") under the
Securities Act ("Affiliates"), may generally only be sold in compliance with the
limitations of Rule 144 described below.
 
     Prior to this offering, there has been no public market for the Common
Stock of the Company, and no assurance can be given that a significant public
market for the Common Stock can be developed or sustained after this offering.
Future sales of substantial amounts of Common Stock in the public market could
have a material adverse effect on the market price of the Common Stock from time
to time.
 
SALE OF RESTRICTED SHARES
 
     The 6,200,000 shares of Common Stock not being sold in this offering are
deemed "restricted securities" under Rule 144 and may be eligible for sale in
the public market in accordance with certain volume and other restrictions under
Rule 144 beginning 90 days after the date of this Prospectus. Notwithstanding
the ability to resell their shares under Rule 144, the current shareholders have
executed lock-up agreements ("Lock-up Agreements") with the Representative
providing that such shareholders will not offer, sell or otherwise dispose of
any of their shares of Common Stock without the prior written consent of the
Representative, for a period of 180 days after the date of this Prospectus.
 
     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated), including an Affiliate, who has beneficially owned
restricted securities for at least two years is entitled to sell, within any
three-month period, a number of shares that does not exceed the greater of (i)
one percent of the then outstanding shares of Common Stock (approximately 87,000
shares immediately after this offering) and (ii) the average weekly trading
volume in the Common Stock in the over-the-counter market during the four
calendar weeks preceding the date on which notice of such sale is filed,
provided certain requirements concerning the availability of public information,
manner of sale and notice of sale are satisfied. In addition, Affiliates must
comply with the restrictions and requirements of Rule 144, other than the
two-year holding period requirement, in order to sell shares of Common Stock
which are not restricted securities. Also, under Rule 144(k), a person who is
not an Affiliate and has not been an Affiliate for at least three months prior
to the sale and who has beneficially owned restricted securities for at least
three years may resell such shares without compliance with the foregoing
requirements. In meeting the two and three year holding periods described above,
a holder of restricted securities can include the holding periods of a prior
owner who was not an Affiliate. The Securities and Exchange Commission has
proposed an amendment to Rule 144 which would reduce the holding period required
for shares subject to Rule 144 to become eligible for sale in the public market
from two years to one year, and from three years to two years in the case of
Rule 144(k).
 
SHARES RESERVED FOR ISSUANCE
 
     Options.  The Company has reserved 1,250,000 shares of Common Stock for
issuance upon exercise of stock options granted under its stock option plan. No
options have been granted to date under the Plan. See "Management -- Stock
Option Plan."
 
     The Company intends to file a Registration Statement on Form S-8 under the
Securities Act to register all shares of Common Stock issuable pursuant to the
Company's stock option plan. The Company expects to file such Registration
Statement 90 days following the closing of this offering, and such Registration
Statement is expected to become effective upon filing. Shares covered by such
Registration Statement will thereupon be eligible for sale in the public
markets, subject to Rule 144 limitations with respect to Affiliates.
 
     Warrants.  The Company has reserved 250,000 shares of Common Stock for
issuance upon exercise of the Representative's Warrants. The holders of the
Representative's Warrants have certain demand and piggyback registration rights.
See "Underwriting."

LOCK-UP AGREEMENTS
 
     The Company and all of its officers, directors and current shareholders
have agreed, pursuant to the Lock-up Agreements, not to directly or indirectly,
without the prior written consent of the Representative, offer, sell, or
otherwise dispose of any shares of Common Stock beneficially owned by them for a
period of 180 days after the date of this Prospectus.
 
     No predictions can be made as to the effect, if any, that future sales of
shares, or the availability of shares for future sale, will have on the
prevailing market price of the Common Stock. Sales of substantial amounts of
Common Stock, or the perception that such sales could occur, could materially
adversely affect the prevailing market prices for the Common Stock and could
impair the Company's future ability to obtain capital through an offering of
equity securities.

                          DESCRIPTION OF CAPITAL STOCK
 
     The Company is authorized to issue 5,000,000 shares of Preferred Stock,
$.01 par value, none of which is outstanding, and 25,000,000 shares of Common
Stock, $.01 par value, 6,200,000 of which are issued and outstanding and held by
three shareholders.
 
PREFERRED STOCK
 
     The Preferred Stock may be issued from time to time by the Board of
Directors in one or more series and classes and with such dividend rights,
conversion rights, voting rights, redemption provisions, liquidation preferences
and other rights and restrictions as the Board of Directors may determine. The
issuance of the Preferred Stock permits the Board of Directors, without
shareholder approval, to utilize the Preferred Stock as an anti-takeover device
which could have an adverse effect on the market price of the Common Stock. The
Company has no present intention to issue any shares of Preferred Stock.
 
COMMON STOCK
 
     Each holder of Common Stock is entitled to one vote for each share held of
record. Subject to the rights of any holders of Preferred Stock which may be
issued in the future, the holders of outstanding shares of Common Stock are
entitled to share ratably on a share-for-share basis with respect to any
dividends when, as and if declared by the Board of Directors out of funds
legally available therefor. Upon liquidation, dissolution or winding up of the
Company, the holders of Common Stock are entitled to share ratably in the assets
remaining after payment of all liabilities and liquidation preferences, if any.
Shares of Common Stock are not redeemable and have no preemptive or similar
rights to subscribe for additional shares. All outstanding shares of Common
Stock are, and the shares of Common Stock offered hereby will upon issuance and
payment be, fully paid and nonassessable.
 
LIMITED LIABILITY AND INDEMNIFICATION
 
     As permitted by the New York Business Corporation Law ("BCL"), the
Company's Restated Certificate of Incorporation provides that, to the fullest
extent permitted by the BCL, no director of the Company shall be liable to the
Company or its shareholders for monetary damages for the breach of fiduciary
duty in such capacity. Such provision does not eliminate or limit the liability
of any director (i) if a judgment or other final adjudication adverse to such
director establishes that his acts or omissions were in bad faith or involved
intentional misconduct or a knowing violation of law or that he personally
gained in fact a material profit or other advantage to which he was not legally
entitled or that his acts violated Section 719 of the BCL, or (ii) for any act
or omission prior to the adoption of this provision. As a result of this
provision, the Company and its shareholders may be unable to obtain monetary
damages from a director for breach of his duty of care. Although shareholders
may continue to seek injunctive or other equitable relief for an alleged breach
of fiduciary duty by a director, shareholders may not have any effective remedy
against the challenged conduct if equitable remedies are unavailable. In
addition, under the Restated Certificate of Incorporation, the Company has
agreed to indemnify its officers, directors, employees and agents to the fullest
extent permitted by the BCL against actions that may arise against them in such
capacities, and to advance expenses in connection with any such actions.
 
NEW YORK BUSINESS COMBINATION STATUTE
 
     Section 912 of the BCL prohibits a company from entering into a business
combination (e.g., a merger, consolidation, sale of 10% or more of a company's
assets, or issuance of securities with an aggregate market value of 5% or more
of the aggregate market value of all of the company's outstanding capital stock)
with a beneficial owner of 20% or more of a company's securities (a "20%
shareholder") for a period of five years following the date such beneficial
owner became a 20% shareholder (the "stock acquisition date"), unless, among
other things, such business combination or the purchase of stock resulting in
the 20% shareholder's beneficial ownership was approved by the company's board
of directors prior to the stock acquisition date or the business combination is
approved by the affirmative vote of the holders of a majority of the outstanding
 
                                       34
<PAGE>   36
 
voting stock exclusive of the stock beneficially owned by the 20% shareholder.
The applicability of this provision to the Company may discourage unsolicited
takeover bids by third parties.
 
TRANSFER AGENT
 
     American Stock Transfer & Trust Company, 40 Wall Street, New York, New York
10005 is the transfer agent and registrar for the Common Stock.

</TABLE>
 
     The Underwriters are committed to take and to pay for all of the shares of
Common Stock offered hereby, if any are purchased.
 
     The Underwriters have advised the Company that they propose to offer all or
part of the Common Stock offered hereby directly to the public initially at the
price set forth on the cover page of this Prospectus, that they may offer shares
to certain dealers at a price that represents a concession of not more than
$          per share, and that the Underwriters may allow, and such dealers may
reallow, a concession of not more than $          per share to certain other
dealers. After the commencement of this offering, the price to the public and
the concessions may be changed.
 
     The Company has granted to the Underwriters an option, exercisable within
30 days after the date of this Prospectus, to purchase up to an additional
375,000 shares of Common Stock at the same price per share as the initial
2,500,000 shares to be purchased by the Underwriters. The Underwriters may
exercise this option only to cover over-allotments, if any. To the extent the
Underwriters exercise this option, each of the Underwriters will have a firm
commitment, subject to certain conditions, to purchase the same percentage
thereof as the percentage of the initial 2,500,000 shares to be purchased by
that Underwriter.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including certain liabilities under the Securities Act, and to
contribute to payments the Underwriters may be required to make in respect
thereof.
 
     The Company has agreed to issue to the Representative, for its own account,
warrants (the "Representative's Warrants") to purchase an aggregate of 250,000
shares of Common Stock, exercisable for a period of four years commencing one
year after the date hereof, at a price equal to 120% of the public offering
price, subject to adjustment in certain events. The Representative's Warrants
contain certain registration rights relating to the shares issuable thereunder.
For the life of the Representative's Warrants, the Representative will have the
opportunity to profit from a rise in the market price for the Common Stock.
 
     The Company, its officers, directors and present shareholders have agreed
not to sell or otherwise dispose of any equity securities of the Company or any
securities convertible into or exchangeable for, or any rights to purchase or
acquire, equity securities of the Company for a period of 180 days after the
date of this Prospectus without the prior written consent of the Representative.
 
     The Representative has informed the Company that the Underwriters do not
expect sales to discretionary accounts to exceed 5% of the total number of
shares offered hereby and that the Underwriters do not intend to confirm sales
of shares to any account over which they exercise discretionary authority.
 
     The Underwriters have reserved for sale, at the initial public offering
price, up to 5% of the Common Stock offered hereby for employees and directors
of the Company and certain other individuals who have
 
                                       36
<PAGE>   38
 
expressed an interest in purchasing such shares of Common Stock in this
offering. The number of shares available for sale to the general public will be
reduced to the extent such persons purchase such reserved shares. Any reserved
shares not so purchased will be offered by the Underwriters to the general
public on the same basis as other shares offered hereby.
 
     Prior to this offering, there has been no public market for the Common
Stock. The proposed initial offering price has been determined by negotiations
between the Representative and the Company. Among the factors considered in such
negotiations were the Company's results of operations and financial condition,
the prospects for the Company and for the industry in which the Company
operates, the Company's capital structure, and the general condition of the
securities market. The estimated offering price set forth on the cover of this
Prospectus is subject to change as a result of market conditions and other
factors.
 
                                 LEGAL MATTERS
 
     Certain legal matters with respect to the validity of the shares of Common
Stock offered hereby will be passed upon for the Company by Epstein Becker &
Green, P.C., New York, New York. Certain legal matters will be passed upon for
the Underwriters by Fulbright & Jaworski L.L.P., New York, New York.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders
Manchester Equipment Co., Inc.:
 
We have audited the accompanying consolidated balance sheets of Manchester
Equipment Co., Inc. and subsidiaries as of July 31, 1996 and 1995 and the
related consolidated statements of income, shareholders' equity and cash flows
for each of the years in the three-year period ended July 31, 1996. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 Manchester Equipment
Co., Inc. and subsidiaries at July 31, 1996 and 1995, and the results of their
operations and their cash flows for each of the years in the three-year period
ended July 31, 1996, in conformity with generally accepted accounting
principles.
 
As discussed in note 1 to the consolidated financial statements, the Company
changed its method of accounting for income taxes in fiscal 1994.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                          JULY 31, 1994, 1995 AND 1996
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
(1) BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  (a) Business
 
     Manchester Equipment Co., Inc. (the "Company") is a systems integrator of
computer hardware, software and networking products, primarily for commercial
customers. The Company offers its customers single-source solutions customized
to their information systems needs by combining value-added services with
hardware, software, networking products and peripherals from leading vendors.
 
     Sales of hardware, software and networking products comprise most of the
Company's revenues. The Company has entered into agreements with certain
suppliers and manufacturers which provide the Company favorable pricing and
price protection in the event the vendor reduces its prices.
 
     In July 1996, the Company executed a letter of intent with an investment
banking firm for a proposed initial public offering ("IPO"). The terms of the
proposed IPO include the sale of 2,500,000 shares of Common Stock, plus an
option in favor of the underwriters for an additional 375,000 shares to provide
for potential over-allotments and warrants in favor of the representative of the
underwriters to purchase 250,000 shares of Common Stock. The net proceeds of the
IPO will be used to retire indebtedness under the bank line of credit, to
relocate or expand the Company's New York City office, for training and expanded
sales facilities in Long Island, to upgrade the Company's internal
telecommunications system and for working capital.
 
  (b) Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All material intercompany transactions and
balances have been eliminated in consolidation.
 
  (c) Cash Equivalents
 
     The Company considers all highly liquid investments with original
maturities at the date of purchase of three months or less to be cash
equivalents.
 
  (d) Revenue Recognition
 
     Revenues from product sales are recognized at the time of shipment to the
customer. Revenues for services are recognized when the related services are
performed. Service contract fees are recognized as revenue ratably over the
period of the applicable contract or as the services are provided. Deferred
service contract revenue represents the unearned portion of service contract
fees.
 
  (e) Market Development Funds
 
     The Company receives various market development funds including cooperative
advertising funds from certain vendors, principally based on volume purchases of
products or pre-approved market development activities (i.e., training,
advertising, etc.). The Company records such amounts as a reduction of cost of
revenues.
 
  (f) Inventory
 
     Inventory, consisting of computer hardware and peripherals, software and
related supplies, is valued at the lower of cost (first-in, first-out) or market
value.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                          JULY 31, 1994, 1995 AND 1996
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
  (g) Property and Equipment
 
     Property and equipment are stated at cost. Depreciation is provided using
the straight-line and accelerated methods over the economic lives of the assets,
generally from five to seven years. Leasehold improvements are amortized over
the shorter of the underlying lease term or asset life.
 
  (h) Income Taxes
 
     Effective August 1, 1993, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes" ("Statement
109"). Statement 109 requires the use of the asset and liability approach for
financial accounting and reporting of income taxes. Under this method, deferred
taxes are recognized for the future tax consequences attributable to temporary
differences between the carrying amounts of assets and liabilities for financial
statement purposes and income tax purposes using enacted tax rates expected to
be in effect when such amounts are realized or settled. The effect on deferred
taxes of a change in tax rates is recognized in income in the period that
includes the enactment date. The Company previously accounted for income taxes
in conformity with APB No. 11. The adoption of Statement 109 resulted in a
cumulative effect adjustment in the Company's 1994 financial statements of $386
and prior years' financial statements were not restated.
 
  (i) Net Income Per Share
 
     Net income per share is based on the weighted average number of shares of
Common Stock and dilutive common stock equivalents (stock options and warrants)
outstanding during the period.
 
  (j) Impairment of Long Lived Assets
 
     In March 1995, the Financial Accounting Standards Board issued SFAS No. 121
("Statement 121") that establishes accounting standards for the impairment of
long lived assets, certain intangibles, and goodwill related to those assets to
be held and used, and for long-lived assets and certain identifiable intangibles
to be disposed of. In conformity with Statement 121, it is the Company's policy
to evaluate and recognize an impairment if it is probable that the recorded
amounts are in excess of anticipated undiscounted future cash flows.
 
  (k) Use of Estimates
 
     Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period to
prepare these financial statements in conformity with generally accepted
accounting principles. Actual results could differ from those estimates.
 
  (l) Fair Value of Financial Instruments
 
     The fair values of cash and cash equivalents, accounts receivable, prepaid
expenses, accounts payable and accrued expenses, capital lease obligation and
notes payable -- shareholder are estimated to be their carrying values at July
31, 1996 due to the short maturity of such instruments. The book value of notes
payable -- bank approximated fair value since those instruments carry prime or
LIBOR based interest rates that are adjusted for market rate fluctuations.

  (m) Reclassifications
 
     Certain reclassifications were made to prior year amounts to conform with
the fiscal 1996 presentation format.

provides for a general security interest first lien on all of the Company's
assets, to the extent one can be obtained. The line is personally guaranteed by

     A valuation allowance has not been provided in connection with the
Company's deferred tax assets since, based on historical pre-tax earnings and
expected taxable income in the future, the Company believes that it is more
likely than not that such deferred tax assets will be recovered.
 
     As discussed in Note 1, the Company adopted Statement 109 as of August 1,
1993. The cumulative effect of the change in accounting for income taxes of $386
was determined as of August 1, 1993 and is reported separately in the
consolidated statement of income for the year ended July 31, 1994. The
cumulative effect adjustment related principally to the establishment under
Statement 109 of deferred tax assets arising due to the nondeductability of the
allowance for doubtful accounts and deferred compensation expenses.
 
(9) RELATED PARTY TRANSACTIONS
 
     The Company leases executive offices and warehouse space as well as its
corporate offices and sales facilities from entities owned or controlled by
shareholders or officers of the Company. The leases generally cover a period of
ten years and expire at various times from 1998 through 2005. Lease terms
generally include annual increases of five percent. Rent expense for these
facilities aggregated $654, $683 and $1,022 for the years ended July 31, 1994,
1995 and 1996, respectively.
 
     During the year ended July 31, 1994, the Company was related, through
common ownership and control, to Electrograph Systems, Inc. ("Electrograph"), a
value-added distributor of microcomputer peripherals, components and
accessories. Purchases from Electrograph during this period were $385,
substantially all of which was paid by July 31, 1994. In August 1994,
Electrograph was acquired by an unrelated company.
 
(10) SHAREHOLDERS' EQUITY
 
  Recapitalization
 
     In connection with the planned IPO, on October 1, 1996, the Company
effected a recapitalization, which increased the authorized number of shares of
Common Stock from 5,000 to 25,000,000, authorized 5,000,000 shares of Preferred
Stock, effected a 6262.63 for one stock split for all outstanding shares of
Common Stock

                          JULY 31, 1994, 1995 AND 1996

on that date and established a $.01 per share par value for Common Stock. All
references in the accompanying consolidated financial statements and notes
thereto relating to per share and share data have been retroactively adjusted to
reflect the recapitalization.
 
  Shareholders' Agreement
 
     The Company is a party to an agreement among its shareholders whereby upon
termination, retirement, or death of either of the Company's two minority
shareholders, the Company is required to redeem his interest at differing values
stated in the agreement. The Company maintains term life insurance with a face
value of $1,500 to be used towards the purchase of the shares in the event of
the death of each shareholder. One of the minority shareholders retired in
fiscal 1996 and based upon the terms of agreements, payment for the
shareholder's interest in the Company (626,263 shares at that time) was fixed at
$4,710. One of these agreements provided this shareholder an annual option to
redeem one-tenth of his shares commencing in fiscal 1996, at an annual price of
$471 to be paid in equal quarterly installments over the following year. In
connection with these agreements, in May 1996 the Company purchased 62,626
shares of Common Stock from the retired shareholder. The purchase price was
$471, to be paid in four non-interest bearing equal quarterly installments
beginning on May 1, 1996. Such shares were subsequently retired.
 
     In September 1996, among other provisions, the retired shareholder agreed
to terminate his option to sell his remaining shares to the Company, subject to
successful completion of the IPO. In addition, the Company's shareholders
entered into an agreement to terminate the shareholders' agreement upon the
effective date of the IPO.
 
  New Accounting Standard
 
     In October 1995, the Financial Accounting Standards Board issued SFAS 123,
"Accounting for Stock-Based Compensation" ("Statement 123"). Statement 123
establishes financial accounting and reporting standards for stock-based
employee compensation plans. The Statement also applies to transactions in which
an entity issues its equity instruments to acquire goods or services from
nonemployees. Statement 123 encourages a fair value based method of accounting
for employee stock options or similar equity instruments. Entities electing not
to adopt a fair value method must make pro forma disclosures of net income and
earnings per share as if a fair value based method had been applied. The
Statement is effective for fiscal year 1997. The Company has elected not to
adopt a fair value based accounting method for employee stock options and
therefore does not expect that the adoption of Statement 123 will have a
material impact on its financial position or results of operations. The Company
will disclose, commencing in fiscal 1997, the pro forma net income and income
per share as if such method had been used to account for stock-based
compensation costs.
 
  Stock Option Plan
 
     Under the Company's 1996 Incentive and Non-Incentive Stock Option Plan (the
"Plan"), which was approved by the Company's shareholders in October 1996, an
aggregate of 1,250,000 shares of Common Stock are reserved for issuance upon
exercise of options thereunder. Under the Plan, incentive stock options may be
granted to employees and non-incentive stock options may be granted to
employees, directors and such other persons as the Compensation Committee of the
Board of Directors (the "Committee") may determine, at exercise prices equal to
at least 100% (with respect to incentive stock options) and at least 85% (with
respect to non-incentive stock options ) of the fair market value of the Common
Stock on the date of grant. In addition to selecting the optionees, the
Committee will determine the number of shares of Common Stock subject to each
option, the term of each stock option up to a maximum of ten years (five years
for certain employees for incentive stock options), the time or times when the
stock option becomes exercisable, and

otherwise administer the Plan. Incentive stock options expire three months from
the date of the holder's termination of employment with the Company other than
by reason of death or disability. Options may be exercised with cash or Common
Stock previously owned for in excess of six months. No options have been granted
through October 1, 1996 under the Plan.
 
(11) MAJOR CUSTOMER AND VENDORS
 
     The Company sells products and services to customers that are located
primarily in the eastern United States. One customer accounted for approximately
14%, 22% and 16% of total revenues for the years ended July 31, 1994, 1995 and
1996, respectively.
 
     The Company's top four vendors accounted for 20%, 12%, 11% and 10% of total
product purchases for the year ended July 31, 1996. The Company's top two
vendors accounted for 22% and 16% of total product purchases for the year ended
July 31, 1995. The Company's top two vendors accounted for 22% and 15% of total
product purchases for the year ended July 31, 1994.
 
(12) PRO FORMA INFORMATION (UNAUDITED)
 
     The pro forma adjustment discussed below has been made to the historical
results of operations to make the presentations more comparable with respect to
future officer compensation expense and rent expense to related parties.
 
     In connection with the planned IPO, certain officers of the Company have
entered into agreements for the fiscal years ending July 31, 1997 and 1998. The
agreements provide for aggregate compensation of $1,400, exclusive of benefits,
in each year. Pro forma net income includes adjustments to increase net income
for the amounts by which aggregate officers' compensation, which includes the
former Chief Financial Officer's compensation, during each year in the three
years ended July 31, 1996 exceeded the total of the amounts to be paid under the
agreements plus the current annual salary of the Company's present Chief
Financial Officer as well as rents paid to related parties in excess of rents
that will be payable under current leases, as amended, net of applicable income
taxes. The weighted average number of shares outstanding used to determine pro
forma net income per share for the year ended July 31, 1996 was computed as
follows:

ITEM 17.  UNDERTAKINGS.
 
     Registrant hereby undertakes to provide to the Underwriters at the closing
specified in the Underwriting Agreement 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
of 1933, as amended (the "Act"), may be permitted to directors, officers and
controlling persons of Registrant pursuant to the provisions of its Restated
Certificate of Incorporation, its By-Laws, or otherwise, Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities
 
                                      II-2
<PAGE>   57
 
(other than the payment by Registrant for expenses incurred or paid by a
director, officer or controlling person of Registrant 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,
Registrant 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 Act and will be governed by the final adjudication of such
issue.
 
     Registrant hereby further undertakes that:
 
          (1) For purposes of determining any liability under the 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 Registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Act shall be deemed to be part of this Registration
     Statement as of the time it was declared effective.
 
          (2) For purposes of determining any liability under the 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.

         SIXTH: Except to the extent that such rights shall be specifically
provided for in the resolution or resolutions adopted by the Board of Directors
providing for the issuance of any series of Preferred Stock, no holder of any of
the shares of any class of the Corporation shall be entitled as of right to
subscribe for, purchase, or otherwise acquire any shares of any class of the
Corporation which the Corporation proposes to issue or any rights or options
which the Corporation proposes to grant for the purchase of shares of any class
of the Corporation or for the purchase of any shares, bonds, securities, or
obligations of the Corporation which are convertible into or exchangeable for,
or which carry any rights to subscribe for, purchase or otherwise acquire shares
of any class of the Corporation; and any and all of such shares, bonds,
securities, or obligations of the Corporation, whether now or hereafter
authorized or created, may be issued, or may be reissued or transferred if the
same have been reacquired and have treasury status, and any and all such rights
and options may be granted by the Board of Directors to such persons, firms,
corporations and associations, and for such lawful consideration, and on such
terms, as the Board of Directors in its discretion may determine, without first
offering the same, or any thereof, to any said holder. Without limiting the
generality of the foregoing stated denial of any and all preemptive rights, no
holder of shares of any class of the Corporation shall have any preemptive
rights in respect of the matters, proceedings, or transactions specified in
subparagraphs (1) to (6), inclusive, of paragraph (e) of Section 622 of the
Business Corporation Law of the State of New York.

         SEVENTH: The number of Directors of the Corporation constituting the

The Board of Directors shall determine from time to time the number of Directors
who shall constitute the entire Board of Directors. Any such determination made
by the Board of Directors shall continue in effect unless and until changed by
the Board of Directors, but no such changes shall affect the term of any
directors then in office. Directors need not be shareholders of the Corporation.

                  Any vacancy on the Board of Directors that results from an
increase in the number of directors and any other vacancy on the Board may be
filled by vote of the shareholders or by the Board provided that a quorum is
then in office and present, or by a majority of the Directors then in office, if
less than a quorum is then in office, or by a sole remaining director. A
director elected to fill a newly created directorship or other vacancy, unless
elected by the shareholders, shall hold office until the next meeting of
shareholders at which the election of directors is in the regular course of
business, and until his successor has been elected and qualified.

                  The directors of the Corporation may not be removed prior to
the expiration date of their terms of office except for cause, either by action
of the Board of Directors or by vote of the shareholders at the Annual Meeting
of Shareholders or at any Special Meeting of Shareholders called by the Board of
Directors or by the Chairman of the Board or by the President for this purpose.

         EIGHTH: To the fullest extent now or hereafter permitted under the New
York Business Corporation Law, no person serving as a director or officer of the
Corporation shall be personally liable to the Corporation or its shareholders
for monetary damages for any breach of fiduciary duty in such capacity. No
amendment or repeal of this Article Eighth shall adversely affect any right or
protection of any director or officer of the Corporation existing at the time of
such amendment or repeal with respect to acts or omissions occurring prior to
such amendment or repeal.

         NINTH: The Corporation shall, to the fullest extent permitted by
Article 7 of the Business Corporation Law of the State of New York, as the same
may be amended and supplemented, or by any successor thereto, indemnify all
persons whom it shall have power to indemnify under said Article from and
against any and all of the expenses, liabilities or other matters referred to in
or covered by said Article. The Corporation shall advance expenses to the
fullest extent permitted by said Article. Such right of indemnification and
advancement or expenses provided for herein shall continue as to a person who
has ceased to be a director, officer, employee or agent of the Corporation and
shall inure to the benefit of the heirs, executors and administrators of such a
person. The indemnification and advancement of expenses provided for herein
shall not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any by-law,
agreement, vote of shareholders, vote of disinterested directors, or otherwise,
as permitted by said Article. Neither the amendment or repeal of this Article
Ninth, nor the adoption of any provision of this Certificate of Incorporation
inconsistent with this Article Ninth shall adversely affect any right or
protection existing under this Article Ninth at the time of such amendment or
repeal."

transaction between the Corporation and one or more of its directors, or between
the Corporation and any other corporation, firm, association or other entity in
which one or more of its directors are directors or officers, or have a
substantial financial interest, shall be either void or voidable for this reason
alone or by reason that such director or directors are present at the meeting of
the Board, or of a committee thereof, which approves such contract or
transaction, or that the votes of such director or directors are counted for
such purposes:

                           (i) If the material facts as to such director's
                           interest in such contract or transaction and as to
                           any common directorship, officership or financial
                           interest are disclosed in good faith or known to the
                           Board or committee, and the Board or committee
                           approves such contract or transaction by a vote
                           sufficient for such purpose without counting the vote
                           or votes of such interested director or directors or,
                           if the votes of the disinterested directors are
                           insufficient to constitute an act of the Board, by
                           unanimous vote of disinterested directors; or

                           (ii) If the material facts as to such director's
                           interest in such contract or transaction and as to
                           any common directorship, officership or financial
                           interest are disclosed in good faith or known to the
                           shareholders entitled to vote thereto, and such
                           contract or transaction is approved by vote of the
                           shareholders.

                    (b) If such good faith disclosure of the material facts as
to the director's interest in the contract or transaction and as to any common
directorship, officership or financial interest is made to the directors or
shareholders, or known to the Board or committee or shareholders entitled to
vote thereon, the contract or transaction may not be avoided by the Corporation
for the reason set forth in Section 1(a) of this Article IV. If there was no
such disclosure or knowledge, or if the vote of such 

                                       5
<PAGE>   6

interested director or directors was necessary for approval of a contract or
transaction at a meeting of the Board or committee at which it was approved, the
Corporation may avoid the contract or transaction unless the parties thereto
shall establish affirmatively that the contract or transaction was fair and
reasonable as to the Corporation at the time it was approved by the Board or
committee or the shareholders.

Ladies and Gentlemen:

            We have acted as counsel to Manchester Equipment Co., Inc. (the
"Company") in connection with its filing of a registration statement on Form S-1
(such registration statement, as amended at the time of its effectiveness,
hereinafter the "Registration Statement") covering shares of the Company's
authorized and unissued shares of Common Stock, $.01 par value, including shares
subject to an over-allotment option (all such shares together with all shares
covered by any related registration statement filed pursuant to Rule 462(b)
under the Securities Act of 1933, as amended, being collectively referred to as
the "Shares").

            As such counsel, we have examined original copies, or copies
certified to our satisfaction, of the corporate records of the Company,
agreements and other instruments, certificates of public officials and such
other documents as we deemed necessary as a basis for the opinion hereinafter
set forth.

            On the basis of the foregoing, we are of the opinion that the Shares
have been validly authorized and, when sold as contemplated by the Registration
Statement, will be legally issued, fully paid and nonassessable.

            We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference made to us under the caption "Legal
Matters" in the prospectus constituting part of the Registration Statement. We
hereby further consent to the incorporation by reference of this opinion in any
related registration statement filed by the Company pursuant to Rule 462(b)
under the Securities Act of 1933, as amended.

                                    Very truly yours,

                         MANCHESTER EQUIPMENT CO., INC.

                        1996 INCENTIVE AND NON-INCENTIVE

                                STOCK OPTION PLAN



1.       Purpose of Plan.

         The purpose of this 1996 Incentive and Non-Incentive Stock Option Plan
("Plan") is to further the growth and development of Manchester Equipment Co.,
Inc. ("Company") and any direct and indirect subsidiaries thereof (collectively,
"Subsidiaries" and each, singly, a "Subsidiary") by encouraging selected
employees, directors and other persons who contribute and are expected to
contribute materially to the Company's success to obtain a proprietary interest
in the Company through the ownership of stock, thereby providing such persons
with an added incentive to promote the best interests of the Company and
affording the Company a means of attracting to its service persons of
outstanding ability.

2.       Stock Subject to this Plan.

         An aggregate of 1,250,000 shares of the Company's Common Stock, par
value $.01 per share ("Common Stock"), subject, however, to adjustment or change
pursuant to Article 10 hereof, shall be reserved for issuance upon the exercise
of options which may be granted from time to time in accordance with this Plan
("Options"). Such shares may be, in whole or in part, authorized but unissued
shares or issued shares which have been reacquired by the Company. If, for any
reason, an Option shall lapse, expire or terminate without having been exercised
in full, the unpurchased shares covered thereby shall again be available for
purposes of this Plan.

3.       Administration.

         (a)      The Board of Directors has appointed a Compensation Committee
                  of the Board of Directors ("Committee") from among its members
                  to administer and help set policy for this Plan. The Committee
                  shall at all times be comprised only of three or more
                  Non-Employee Directors (as defined in Rule 16b-3 under the
                  Securities Exchange Act of 1934, as amended). Such Committee
                  shall have and may exercise any and all of the powers relating
                  to the administration of this Plan and the grant of Options
                  hereunder as are set forth herein. The Board of Directors
                  shall have the power at any time to fill vacancies in, to
                  change the membership of, or to discharge such Committee. The
                  Committee shall select one of its members as its chairman and
                  shall hold its meetings at such time and at such places as it
                  shall deem advisable. A majority of such Committee shall
                  constitute a quorum and such majority shall determine its
                  action. Any action may be taken without a meeting by written
                  consent of all the members of the Committee. The Committee
                  shall keep minutes

                                        1

<PAGE>   2



                  of its proceedings and shall report the same to the Board of
                  Directors at the next meeting of the Board.

         (b)      The Committee shall administer this Plan and, subject to the
                  provisions of this Plan, shall have sole authority in its
                  discretion to determine the persons to whom, and the time or
                  times at which, Options shall be granted, the number of shares
                  to be subject to each such Option and whether all or any
                  portion of such Options shall be incentive stock options
                  ("Incentive Options") qualifying under Section 422 of the
                  Internal Revenue Code of 1986, as amended ("Code"), or stock
                  options which do not so qualify ("Non-Incentive Options").
                  Both Incentive Options and Non- Incentive Options may be
                  granted to the same person at the same time provided each type
                  of Option is clearly designated. In making such
                  determinations, the Committee may take into account the nature
                  of the services rendered by such persons, their present and
                  potential contributions to the Company's success and such
                  other factors as the Committee in its sole discretion may deem
                  relevant. Subject to the express provisions of this Plan, the
                  Committee shall also have the authority to interpret this
                  Plan, to prescribe, amend and rescind rules and regulations
                  relating thereto, to determine the terms and provisions of the
                  respective Option Agreements, which shall be, subject to the
                  rights granted to the Company and the Committee hereunder,
                  substantially in the forms attached hereto as Exhibit A and
                  Exhibit B, with such changes thereto as may be necessary to
                  reflect the - terms and conditions of the grant in question,
                  and to make all other determinations necessary or advisable
                  for the administration of this Plan, all of which
                  determinations shall be conclusive and not subject to review.

4.       Eligibility for Receipt of Options.

         (a)      Incentive Options.

                  Incentive Options may be granted only to employees (including
                  officers) of the Company and/or any of its Subsidiaries.

                  The aggregate Fair Market Value (as defined in Article 5 of
                  this Plan), determined as of the time the Incentive Option is
                  granted, of the shares of the Company's Common Stock
                  purchasable hereunder exercisable for the first time by an
                  employee during any calendar year may not exceed $100,000.

                  A director of the Company or any Subsidiary who is not an
                  employee of the Company or of one of its Subsidiaries is not
                  eligible to receive Incentive Options under this Plan.
                  Further, Incentive Options may not be granted to any person
                  who, at the time the Incentive Option is granted, owns (or is
                  considered as owning within the meaning of Section 424(d) of
                  the Code) stock possessing more than 10% of the total combined
                  voting powers of all classes of stock of the Company or any
                  Subsidiary (a "10% Owner"), unless at the time the Incentive
                  Option is granted to a 10% Owner, the option price is at least
                  110% of the fair market value of the

                                        2

<PAGE>   3



                  Common Stock subject thereto and such Incentive Option by its
                  terms is not exercisable subsequent to five years from the
                  date of grant.

         (b)      Non-Incentive Options.

                  Non-Incentive Options may be granted to any employees
                  (including employees who have been granted Incentive Options),
                  directors, consultants, agents, independent contractors and
                  other persons whom the Committee determines will contribute to
                  the Company's success.

         (c)      Notwithstanding the forgoing, the maximum aggregate number of
                  shares with respect to which Options, whether Incentive or
                  Non-Incentive, may be granted to any person eligible therefor
                  under this Plan within any one calendar year is 200,000
                  shares.

5.       Option Price.

         The purchase price of the shares of Common Stock under each Option
shall be determined by the Committee, which determination shall be conclusive
and not subject to review, but in no event shall such purchase price be less
than (i) 100% of the fair market value of the Common Stock on the date of grant
of Incentive Options (110% of the fair market value of Common Stock on the date
of grant where the grant of Incentive Options is made to a 10% Owner), and (ii)
85% of the fair market value of the Common Stock on the date of grant for
Non-Incentive Options.

         In determining the fair market value of the Common Stock as of a
specified date ("Fair Market Value"), the Committee shall consider, if the
Common Stock is: (a) publicly traded and listed on the New York Stock Exchange
or another national securities exchange or The Nasdaq Stock Market, the closing
sale price of the Common Stock on the business day immediately preceding the
date as of which the Fair Market Value is being determined, or on the next
preceding date on which such Common Stock is traded if no Common Stock was
traded on such immediately preceding business day, or, if the Common Stock is
not so listed on a national securities exchange or The Nasdaq Stock Market, but
publicly traded, the representative closing sale price in the over-the-counter
market as quoted by the National Quotation Bureau or a recognized dealer in the
Common Stock, on the date immediately preceding the date as of which the Fair
Market Value is being determined, or on the next preceding date on which such
Common Stock is traded if no Common Stock was traded on such immediately
preceding business day; or (b) not publicly traded, the fair market value as
determined by the Committee in good faith based on such factors as it shall deem
appropriate. The Committee may also consider such other factors as it shall deem
appropriate.

         For purposes of this Plan, the date of grant of an Option shall be the
date on which the Committee shall by resolution duly authorize such Option.

6.       Term of Options; Termination.

         (a)      The term of each Option shall be such number of years as the
                  Committee shall determine, subject to earlier termination as
                  provided herein and in the Option Agreement (and each
                  Incentive Option being subject to the limitations set forth in
                  Section 4(a) of this Plan with respect to grants to 10%
                  Owners), but in no event shall the term of any Option be more
                  than ten years from the date of grant. No Option may be
                  exercised following termination thereof.

         (b)      If an Incentive Option holder's employment with the Company or
                  a Subsidiary is terminated for any reason other than by reason
                  of death or disability (within the meaning of Section 22(e)(3)
                  of the Code), such holder's Incentive Option shall terminate
                  on the earlier of (i) three (3) months from the date of such
                  termination of employment, or (ii) the expiration date of the
                  term of such Option. Absence on leave approved by the employer
                  corporation shall not be considered an interruption of
                  employment for any purpose under this Plan.

         (C)      If an Incentive Option holder's employment with the Company or
                  a Subsidiary is terminated by reason of such holder's
                  disability within the meaning of Section 22(e)(3) of the Code,
                  subject to paragraph 6(d) hereof, such holder's Incentive
                  Option shall terminate on the earlier of (i) one (1) year from
                  the date of such termination, or (ii) the expiration date of
                  the term of such Option.

         (d)      If an Incentive Option holder dies while in the employ of the
                  Company or a Subsidiary (or within one (1) year following
                  termination of employment due to disability within the meaning
                  of Section 22(e)(3) of the Code), such holder's Incentive
                  Option shall terminate on the earlier of (i) one (1) year from
                  the date of death, or (ii) the expiration date of the term of
                  the Option. To the extent such Incentive Option was
                  exercisable by such holder at the date of death (or the date
                  of termination of employment due to disability within the
                  meaning of Section 22(e)(3) of the Code), such Option may be
                  exercised by the legatee or legatees of such person under such
                  person's Last Will, or by such person's personal
                  representative or distributees, within one (1) year from the
                  date of death but in no event subsequent to the expiration
                  date of the Incentive Option.

7.       Exercise of Options.

         (a)      Incentive and Non-Incentive Options shall be exercisable
                  within the times or upon the events determined by the
                  Committee as set forth in the Option Agreements.

         (b)      An Option may not be exercised for fractional shares of the
                  Company's Common Stock.

         (c)      In the event of a Change in Control (as defined herein), all
                  outstanding Options shall accelerate and become immediately
                  fully exercisable. For purposes of this

                  Plan, a "Change In Control" shall mean (i) the sale or other
                  disposition to a person, entity or group (as such term is
                  defined in Rule 13d-5 under the Securities Exchange Act of
                  1934, as amended) of 50% or more of the Company's consolidated
                  assets, (ii) the acquisition of 50% or more of the outstanding
                  shares by a person or group (as such term is defined in Rule
                  13d-5) or (iii) if the majority of the Company's Board of
                  Directors consists of persons other than the Continuing
                  Directors (as defined herein). The term "Continuing Director"
                  shall mean any member of the Company's Board of Directors on
                  the effective date of this Plan and any other member of the
                  Board of Directors who shall be recommended or elected to
                  succeed or become a Continuing Director by a majority of the
                  Continuing Directors who are then members of the Board of
                  Directors. The aggregate Fair Market Value (determined at the
                  time an Option is granted) of Incentive Options which first
                  become exercisable in the year of such Change in Control
                  cannot exceed $100,000. Any remaining accelerated Options
                  shall be Non-Incentive Options.

         (d)      If an Option holder ceases to be an employee, director,
                  consultant, agent, independent contractor or other person
                  employed by or engaged in performing services for the Company
                  and/or a Subsidiary, the Option held by such person shall be
                  exercisable after the date of termination of employment or
                  engagement only to the extent such Option was exercisable by
                  such holder at the date of termination. In no event shall such
                  option be exercisable following the expiration of its term or
                  earlier termination.

         (e)      The exercise of an Option shall be contingent upon receipt by
                  the Company from the holder of such Option of a written
                  representation that at the time of such exercise it is the
                  Optionholder's then present intention to acquire the Option
                  shares for investment and not with a view to the distribution
                  or resale thereof (unless a Registration Statement covering
                  the shares purchasable upon exercise of the Options shall have
                  been declared effective by the Securities and Exchange
                  Commission) and upon receipt by the Company of cash, or a
                  check to its order, for the full purchase price of such
                  shares. In addition, the holder of such Option must agree to
                  refrain from selling or offering to sell any securities of the
                  Company for such reasonable period of time after the effective
                  date of any registration statement relating to an underwritten
                  offering of securities of the Company, as may be requested by
                  the managing underwriter of such underwritten offering, and
                  approved by the Board of Directors. The Company shall be under
                  no obligation to register the Shares with the Securities and
                  Exchange Commission or to effect compliance with the
                  Securities Act of 1933 or with the registration or
                  qualification requirement of any state securities laws or
                  stock exchange.

         (f)      Payment for the shares of Common Stock may be made (i) in cash
                  or by check to the order of the Company; (ii) by surrender of
                  shares of Common Stock having a Fair Market Value equal to the
                  exercise price of the Option; or (iii) by any combination of 
                  the foregoing



                                        5

<PAGE>   6



                  where approved by the Committee in its sole discretion;
                  provided, however, in the event of payment for the shares of
                  Common Stock by method (ii) above, the shares of Common Stock
                  so surrendered, if originally issued to the Optionholder upon
                  exercise of an Option(s) granted by the Company, shall have
                  been held by the Optionholder for more than six months.


         (g)      The holder of an Option shall have none of the rights of a
                  shareholder with respect to the shares purchasable upon
                  exercise of the Option until a certificate for such shares
                  shall have been issued to the holder upon due exercise of the
                  Option.




                                        6

<PAGE>   7



         (h)      The proceeds received by the Company upon exercise of an
                  Option shall be added to the Company's working capital and be
                  available for general corporate purposes.




8.       Non-Transferability of Incentive Options.

         No Incentive Option granted pursuant to this Plan shall be transferable
otherwise than by will or the laws of descent or distribution and an Incentive
Option may be exercised during the lifetime of the Option holder only by such
Option holder.

9.       No Right of Employment.

         Nothing in this Plan or in any Option Agreement granted hereunder
shall: (a) confer upon any Option holder any right to continue in the employ of
the Company or any Subsidiary or obligate the Company or any Subsidiary to
continue the engagement of any Option holder; or (b) interfere in any way with
the right of the Company or any such Subsidiary to terminate such Option
holder's employment or engagement at any time.

10.      Adjustments Upon Changes in Capitalization.

         If at any time after the date of grant of an Option, the Company shall
by stock dividend, split-up, combination, reclassification or exchange, or
through merger or consolidation or otherwise, change its shares of Common Stock
into a different number or kind or class of shares or other securities or
property, then the number of shares covered by such Option and the price per
share thereof shall be proportionately adjusted for any such change by the
Committee, whose determination thereon shall be conclusive. In the event that a
fraction of a share results from the foregoing adjustment, said fraction shall
be eliminated and the price per share of the remaining shares subject to the
Option adjusted accordingly.

11.      Vesting of Rights Under Options.

         Nothing contained in this Plan or in any resolution adopted or to be
adopted by the Committee or the shareholders of the Company shall constitute the
vesting of any rights under any Option. The vesting of such rights shall take
place only when a written Option Agreement, substantially in the form of the
Incentive Stock Option Agreement attached hereto as Exhibit A or the
Non-Incentive Stock Option Agreement attached hereto as Exhibit B (with such
changes to such Exhibits as may be necessary to reflect the terms and conditions
of the grant in question), shall be duly executed and delivered by and on behalf
of the Company and the person to whom the Option shall be granted, subject,
however, in either event, to the rights granted to the Company and the Committee
hereunder and to the terms and conditions of the Option Agreement.

12.      Withholding Taxes.

         Whenever under this Plan shares are to be issued in satisfaction of the
exercise of Options granted hereunder, the Company shall have the right to
require the recipient to remit to the Company an amount sufficient to satisfy
federal, state and local withholding tax requirements prior to the delivery of
any certificate or certificates for such shares.


13.      Restrictions on Shares.

         At the discretion of the Committee, the Company may reserve to itself
or its assignee(s) in the Option Agreement (a) a right of first refusal to
purchase any shares that an Optionholder (or a subsequent transferee) may
propose to transfer to a third party and (b) a right to repurchase any or all
shares held by an Optionholder upon the Optionee's termination of employment or
service with the Company or a subsidiary for any reason within a specified time
as determined by the Committee at the time of grant at (i) the Optionholder's
original purchase price, (ii) the Fair Market Value of such shares as determined
by the Committee in good faith, or (iii) a price determined by a provision set
forth in the Option Agreement.

14.      Termination and Amendment.

         The Committee may at any time terminate, amend or modify this Plan in
any respect (including, but not limited to, any form of grant, agreement or
instrument to be executed pursuant to this Plan); provided, however, that
shareholder approval shall be required to be obtained by the Company if required
to comply with the Incentive Option provisions or Section 162(m) of the Code, or
the listed company requirements of The Nasdaq Stock Market or of a national
securities exchange on which the shares of Common Stock are traded, or other
applicable provisions of state or federal law or self-regulatory agencies;
provided, further, that no termination, amendment or modification of this Plan
may materially adversely affect the rights of a holder of an Option previously
granted under this Plan without the written consent of such Optionholder.

15.      Term of Plan.

         This Plan was originally adopted by the Board of Directors on October

                        INCENTIVE STOCK OPTION AGREEMENT
                                            

To:


         We are pleased to notify you that by the determination of the
Compensation Committee (hereinafter called the "Committee") an incentive stock
option to purchase ________ shares of the Common Stock of Manchester Equipment
Co., Inc. (herein called the "Company") at a price of $______ per share has this
____ day of _______________, been granted to you under the Company's 1996
Incentive and Non-Incentive Stock Option Plan, as amended (herein called the
"Plan"). This option may be exercised only upon the terms and conditions set
forth below.

         A.       Purpose of Option.

                  The purpose of this Plan under which this incentive stock
option has been granted is to further the growth and development of the Company
and its direct and indirect subsidiaries by encouraging key employees,
directors, consultants, agents, independent contractors and other persons who
contribute and are expected to contribute materially to the Company's success to
obtain a proprietary interest in the Company through the ownership of stock,
thereby providing such persons with an added incentive to promote the best
interests of the Company, and affording the Company a means of attracting to its
service persons of outstanding ability.

                  1.       Acceptance of Option Agreement.

                           Your execution of this incentive stock option
agreement will indicate your acceptance of and your willingness to be bound by
its terms; it imposes no obligation upon you to purchase any of the shares
subject to the option. Your obligation to purchase shares can arise only upon
your exercise of the option in the manner set forth in Article 3 hereof.

                  2.       When Option May Be Exercised.

                           The option granted you hereunder may not be exercised
for a period of [one year] from the date of its grant by the Committee as set
forth above. Thereafter, this option shall be exercisable as follows:

                           (i)      at the end of [one year] from the date of
                                    grant, up to [25%] of the total shares
                                    subject to the option;

                           (ii)     at the end of the [second year] from the
                                    date of grant, up to [50%] of such shares;

                           (iii)    at the end of the [third year] from the date
                                    of grant, up to [75%] of such shares;



                                        1

<PAGE>   11



                           (iv)     at the end of the fourth year from the date
                                    of grant, up to [100%] of such shares.

This option may not be exercised for less than ten shares at any one time (or
the remaining shares then purchasable if less than ten) and expires at the end
of ten years from the date of grant whether or not it has been duly exercised,
unless sooner terminated as provided in Articles 5, 6 and 7 hereof.

                  3.       How Option May Be Exercised.

                           This option is exercisable by a written notice signed
by you and delivered to the Company at its executive offices, signifying your
election to exercise the option. The notice must state the number of shares of
Common Stock as to which your option is being exercised, must contain a
statement by you (in a form acceptable to the Company) that such shares are
being acquired by you for investment and not with a view to their distribution
or resale (unless a registration statement covering the shares purchasable has
been declared effective by the Securities and Exchange Commission) and must be
accompanied by payment as set forth in Article 4 hereof for the full purchase
price of the share being purchased. No share shall be issued until full payment
therefor has been made.

                           If notice of the exercise of this option is given by
a person or persons other than you, the Company may require, as a condition to
the exercise of this option, the submission to the Company of appropriate proof
of the right of such person or persons to exercise this option.

                           Certificates for shares of the Common Stock so
purchased will be issued as soon as practicable. The Company, however, shall not
be required to issue or deliver a certificate for any shares until it has
complied with all requirements of the Securities Act of 1933, the Securities
Exchange Act of 1934, any stock exchange on which the Company's Common Stock may
then be listed and all applicable state laws in connection with the issuance or
sale of such shares or the listing of such shares on said exchange. Until the
issuance of the certificate for such shares, you or such other person as may be
entitled to exercise this option, shall have none of the rights of a shareholder
with respect to shares subject to this option.

                           You shall promptly advise the Company of any sale of
shares of Common Stock issued upon exercise of this option which occurs within
one (1) year from the date of the exercise of this option relating to the
issuance of such shares.

                  4.       Payment of Options.

                           Payment for the shares of Common Stock may be made
(i) in cash or by check to the order of the Company, (ii) by surrender of
shares of Common Stock having a Fair Market Value equal to the exercise price
of the Option; or (iii) by any combination of the foregoing where approved by 
the Committee in its sole discretion; provided, however, in the event of
payment for the shares of Common Stock by method (ii) above, the shares of
Common Stock so surrendered, if originally issued to you upon exercise of an
option(s) granted by the Company, shall have been held by you for more than
six months.

                  5.       Termination of Employment.

                           If your employment with the Company (or a subsidiary
thereof) is terminated for any reason other than by death or disability, this
option shall terminate three (3) months from the date of such termination of
employment (but in no event shall you be able to exercise this option after ten
years from the date this option was granted to you), provided, however, you
shall only be entitled to exercise that portion of this option which was
exercisable by you at the date of such termination of employment.

                  6.       Disability.

                           If your employment with the Company (or a subsidiary
thereof) is terminated by reason of your disability, you may exercise, within
one (1) year from the date of such termination, that portion of this option
which was exercisable by you at the date of such termination, provided, however,
that such exercise occurs within ten years from the date this option was granted
to you.

<PAGE>   13

                  7.       Death.

                           If you die while employed by the Company (or a
subsidiary thereof) or within one (1) year after termination of your employment
due to disability, that portion of this option which was exercisable by you at
the date of your death may be exercised by your legatee or legatees under your
Last Will, or by your personal representatives or distributees, within one (1)
year from the date of your death, provided, however, that such exercise occurs
within ten years from the date this option was granted to you.

                  8.       Non-Transferability of Option.

                           This option shall not be transferable except by Last
Will or the laws of descent and distribution, and may be exercised during your
lifetime only by you.

                  9.       Adjustments upon Changes in Capitalization.

                           If at any time after the date of grant of this
option, the Company shall, by stock dividend, split-up, combination,
reclassification or exchange, or through merger or consolidation, or otherwise,
change its shares of Common Stock into a different number or kind or class of
shares or other securities or property, then the number of shares covered by
this option and the price of each such share shall be proportionately adjusted
for any such change by the Committee whose determination shall be conclusive.
Any fraction of a share resulting from any adjustment shall be eliminated and
the price per share of the remaining shares subject to this options adjusted
accordingly.

                  10.      Subject to Terms of this Plan.

                           This incentive stock option agreement shall be
subject in all respects to the terms and conditions of this Plan and in the
event of any question or controversy relating to the terms of this Plan, the
decision of the Committee shall be conclusive.

                                       Sincerely yours,

                                       MANCHESTER EQUIPMENT CO., INC.

                  4.       How Option May Be Exercised.


                           This option is exercisable by a written notice signed
by you and delivered to the Company at its executive offices, signifying your
election to exercise the option. The notice must state the number of shares of
Common Stock as to which your option is being exercised, must contain a
statement by you (in a form acceptable to the Company) that such shares are
being acquired by you for investment and not with a view to their distribution
or resale (unless a registration statement covering the shares purchasable has
been declared effective by the Securities and Exchange Commission) and must be
accompanied by payment as set forth in Article 5 hereof for the full purchase
price of the shares being purchased, plus such amount, if any, as is required
for withholding taxes. No share shall be issued until full payment therefor has
been made.

                           If notice of the exercise of this option is given by
a person or persons other than you, the Company may require, as a condition to
the exercise of this option, the submission to the Company of appropriate proof
of the right of such person or persons to exercise this option.

                           Certificates for shares of the Common Stock so
purchased will be issued as soon as practicable. The Company, however, shall not
be required to issue or deliver a certificate for any shares until it has
complied with all requirements of the Securities Act of 1933, the Securities
Exchange Act of 1934, any stock exchange on which the Company's Common Stock may
then be listed and all applicable state laws in connection with the issuance or
sale of such shares or the listing of such shares on said exchange. Until the
issuance of the certificate for such shares, you or such other person as may be
entitled to exercise this option, shall have none of the rights of a shareholder
with respect to shares subject to this option.

                  5.       Payment of Options.

                           Payment for the shares of Common Stock may be made
(i) in cash or by check to the order of the Company, (ii) by surrender of shares
of Common Stock having a Fair Market Value equal to the exercise price of the
Option; or (iii) by any combination of the foregoing where approved by the
Committee in its sole discretion; provided, however, in the event of payment for
the shares of Common Stock by method (ii) above, the shares of Common Stock so
surrendered, if originally issued to you upon exercise of an option(s) granted
by the Company, shall have been held by you for more than six months.

                  6.       Termination of Employment or Engagement.

                           If your employment or engagement with the Company (or
a subsidiary thereof) is terminated for any reason, [INSERT TERMS UPON WHICH
NON-INCENTIVE OPTION HOLDER'S OPTIONS SHALL LAPSE AND EXPIRE.] [INSERT TERMS
UPON WHICH NON-INCENTIVE OPTIONS SHALL SURVIVE THE TERMINATION OF A HOLDER'S
EMPLOYMENT OR ENGAGEMENT, BUT IN SUCH EVENT THE OPTION SHALL BE EXERCISABLE ONLY
TO THE EXTENT EXERCISABLE ON THE DATE OF SUCH TERMINATION AND IN NO EVENT SHALL
THE OPTION BE EXERCISABLE AFTER THE EXPIRATION DATE OF THIS OPTION.] [IF THE
OPTION SURVIVES THE DEATH OF THE OPTION HOLDER, ADD LANGUAGE THAT IT MAY BE
EXERCISED BY THE HOLDER'S LEGATEE OR LEGATEES UNDER HIS LAST WILL, OR BY HIS
PERSONAL REPRESENTATIVES OR DISTRIBUTEES.]

                  7.       Adjustments upon Changes in Capitalization.

                           If at any time after the date of grant of this
option, the Company shall, by stock dividend, split-up, combination,
reclassification or exchange, or through merger or consolidation, or otherwise,
change its shares of Common Stock into a different number or kind or class of
shares or other securities or property, then the number of shares covered by
this option and the price of each such share shall be proportionately adjusted
for any such change by the Committee whose determination shall be conclusive.
Any fraction of a share resulting from any adjustment shall be eliminated and
the price per share of the remaining shares subject to this option adjusted
accordingly.

                  8.       Subject to Terms of this Plan.

                           This non-incentive stock option agreement shall be
subject in all respects to the terms and conditions of this Plan and in the
event of any question or controversy relating to the terms of this Plan, the
decision of the Committee shall be conclusive.

                  9.       Tax Status.

                           This option does not qualify as an "incentive stock
option" under the provisions of Section 422 of the Internal Revenue Code of
1986, as amended, and the income tax implications of your receipt of a
non-incentive stock option and your exercise of such an option should be
discussed with your tax counsel.

                                       Sincerely yours,

                                       MANCHESTER EQUIPMENT CO., INC.

<PAGE>   2
     WHEREAS, for various reasons, the Underwriter has requested that BIVONA
enter into an Agreement with MANCHESTER, at this time, pertaining to the BIVONA
shares. NOW, THEREFORE, IN CONSIDERATION OF THE SUM OF $10.00 EACH TO THE OTHER
IN HAND PAID, AND IN FURTHER CONSIDERATION OF THE TERMS AND CONDITIONS OF THE
WITHIN AGREEMENT, IT IS AGREED AS FOLLOWS:

     First: MANCHESTER and BIVONA herein agree that the Agreement and Addendum
to Agreement of May 7, 1996 (the Agreement) as between them is herein
incorporated by reference, with the same force and effect as if same were fully
set forth herein.

     SECOND: Reference is herein made to the provisions of Paragraph Fifth
"Mandatory Election by Bivona" of the Agreement, as hereinafter set forth:

     "FIFTH: MANDATORY ELECTION BY BIVONA -- At all times subsequent to the
     execution of the within Agreement, in the event the Company enters into an
     Underwriting Agreement for IPO purposes, Bivona, shall have thirty (30)
     days after the mailing to him, Certified Mail, Return Receipt, of a written
     notice of the execution of such Underwriting Agreement, to make an election
     as to the following:

          A. To continue the terms of the within Agreement, i.e., the Rights of
     Election Rights herein granted to Bivona (PARAGRAPH FOURTH:) shall continue
     and remain in effect; the result of which is that the total of the then
     remaining Bivona shares shall BE "restricted" from sale or any other
     disposition by Bivona, other than the "Rights of Election" herein granted
     to him as set forth in PARAGRAPH FOURTH: of the within Agreement.

                                       OR


                                       2

<PAGE>   3
                        B. To avoid the "Rights of Election" provisions of the
                PARAGRAPH FOURTH: i.e. The Bivona shares will no longer be
                restricted in any manner as Agreement as to the Election Rights
                herein granted to Bivona (PARAGRAPH FOURTH;) i.e., the Bivona
                stock would no longer be restricted in any manner as to sale or
                other disposition; PROVIDED, HOWEVER, the said Bivona shares
                will then be subject to any "LOCK-UP" Agreements as may be
                required by either the Underwriter representing the Company as
                to the IPO, or the restrictions placed on said stock by all
                applicable SEC Rules and Regulations.

                        1)      Bivona shall exercise the Election granted to
                him by the terms of the within Paragraph, pursuant to a written
                notice thereof forwarded to the Company, Certified Mail, Return
                Receipt. The failure of Bivona to make such Election in the time
                and manner as aforesaid, shall be deemed as an automatic
                Election by Bivona to continue the "Rights of Election" granted
                to Bivona as per PARAGRAPH FOURTH; of the within Agreement, and
                as to A. OF THE WITHIN PARAGRAPH."

"After-Market", following the initial Lock-Up period, will be as follows:

        The right to sell {in brokerage transactions}, in any three month
period, such

                                       3
<PAGE>   4
number of shares not exceeding the greater of {i} One {1%} percent of the then
outstanding shares of common stock of Manchester, and {ii} The average weekly
trading volume in the Manchester common stock, in the over-the-counter market,
during the preceding four calendar weeks.

        B.  In the event of a secondary public offering by Manchester, at such
time as Bivona should still be the owner of any of the original Manchester
shares presently owned by him, Bivona is herein granted so-called "Piggyback"
registration rights as to such remaining shares; provided, however, that such
registration rights will be in a direct proportion to the percentage of shares
being registered by Barry R. Steinberg, the principal shareholder of 
Manchester.

        EXAMPLE: Steinberg proposes to register ten {10%} percent of his
remaining Manchester shares in a secondary offering - Bivona shall have the
right to have included in such offering no more than ten {10%} percent of his
then remaining original Manchester shares.

        The provisions of the within sub-paragraph B. shall further apply to any
tertiary or later public offering by Manchester, in the event Bivona should

the Agreement, pertaining to the Life Insurance Programs {policies} presently
maintained by Manchester as to the life of Bivona.

        The provisions of said Paragraph Ninth of the Agreement will be deemed
deleted from the Agreement in their entirety, and of no further force and


                                       4
<PAGE>   5
effect; provided however, that prior to the cancellation by Manchester of said
Life Insurance policies, or either of them, Manchester shall offer to assign
said policy or policies to BIVONA or his nominees for a consideration of Ten
($10.00) Dollars.

                D.  Reference is herein made to the provisions of Paragraph
THIRD of the Agreement pertaining to the Stockholders' Agreement of September
18, 1990, as between Manchester, and Messrs. Steinberg, Stemple and Bivona, as
the then sole Stockholders of Manchester.

                        All of the terms, covenant and conditions of the said
Stockholders' Agreement are herein deemed to be of no further force and effect,
and is to be deemed terminated as to the effective date of the closing of the
Initial Public Offering.

                E.  Reference is herein made to the provisions of Paragraph
TWELFTH of the Agreement pertaining to the BIVONA medical and hospital benefits
to be maintained by MANCHESTER. MANCHESTER herein agrees that it will maintain
the presently existing medical and hospital insurance for the benefit of BIVONA
until June 1, 1999, at which time the obligation of MANCHESTER to maintain such
coverage shall automatically cease and terminate.

        FOURTH:  BIVONA and MANCHESTER herein acknowledge that the execution of
the within Agreement by BIVONA shall be deemed to be the exercise of the
"Rights of Election" granted to him by Paragraph FIFTH of the Agreement, and as
cited in Paragraph SECOND of the within Agreement.

of the

                                       5

the Initial Public Offering as contemplated by the Letter of Intent between
Ladenburg, Thalmann & Co., Inc., as the Underwriter and MANCHESTER. In the
event the said Initial Public Offering is not concluded for any reason
whatsoever, the terms and conditions of the within Agreement shall be deemed
null and void, of no further force and effect, AND the provisions of Paragraph
FIFTH (all parts) of the Agreement shall remain in full force and effect.

        SIXTH:   This Agreement shall be binding upon the parties hereto, and
their respective heirs, successors and/or assigns.

               agents, visitors or licensees, without prejudice to any other
               rights and remedies of Landlord and without prejudice to the
               rights of subrogation of Landlord's insurer, the damages shall
               be repaired by Landlord but there shall be no apportionment or
               abatement of rent. No penalty shall accrue for reasonable delay
               which may arise reason of adjustment of insurance on the part of
FIRE CAUSE     Landlord and/or Tenant, and for reasonable delay on account of
               "labor troubles", or any other cause beyond Landlord's control.
               If the demised premises are totally damaged or are rendered
               wholly untenantable by fire or other cause, and if Landlord
               shall decide not to restore or not to rebuild the same, or if
               the building shall be so damaged that Landlord shall decide to
               demolish it or to rebuild it, then or in any of such events
               Landlord may, within ninety (90) days after such fire or other
               cause, give Tenant a notice in writing of such decision, which
               notice shall be given as in Paragraph Twelve hereof provided,
               and thereupon the term of this lease shall expire by lapse of
               time upon the third day after such notice is given, and Tenant
               shall vacate the demised premises and surrender the same to
               Landlord. If Tenant shall not be in default under this lease
               then, upon the termination of this lease under this lease then,
               upon the termination of this lease under the conditions provided
               for in the sentence immediately preceding, Tenant's liability
               for rent shall cease as of the day following the casualty.
               Tenant hereby expressly waives the provisions of Section 227 of
               the Real Property Law and agrees that the foregoing provisions
               of this Article shall govern and control in lieu thereof. If the
               damage or destruction be due to the fault or neglect or Tenant
               the debris shall be removed by, and at the expense of, Tenant.

EMINENT             FIFTH.--If the whole or any part of the premises heeby
DOMAIN         demised shall be taken or condemned by any competent authority
               for any public use of purpose then the term hereby granted shall
               cease from the time when possession of the part so taken shall
               be required for such public purpose and without apportionment of
               award, the Tenant hereby assigning to the Landlord all right and
               claim to any such award, the current rent, however, in such
               case to be apportioned.

LEASE NOT           SIXTH.--If, before the commencement of the term, the Tenant
IN EFFECT      be adjudicated a bankrupt, or make a "general assignment," or
               take the benefit of any insolvent act, or if a Receiver or
               Trustee be appointed for the Tenant's property, or if this lease
               or the estate of the Tenant hereunder be transferred or pass to
               or devolve upon any other person or corporation, or if the 
               Tenant shall default in the performance of any agreement by the
               Tenant contained in any other lease to the Tenant by the
               Landlord or by any corporation of which an officer of the
               Landlord is a Director, this lease shall thereby, at the option
               of the Landlord, be terminated and in that case, neither the
               Tenant nor anybody claiming under the Tenant shall be entitled
               to go in possession of the demised premises. If after the
               commencement of the term, any of the events mentioned above in
               this subdivision shall occur, or if Tenant shall make default in
               fulfilling any of the covenants of this lease, other than the
DEFAULTS       covenants for the payment of rent or "additional rent" or if the
               demised premises become vacant or deserted, the Landlord may
               give to the Tenant ten days' notice of intention to end the term
               of this lease, and thereupon at the expiration of said ten days'
               (if said condition which was the basis of said notice shall
               continue to exist) the term under this lease shall expire as
               full and completely as if that day were the date herein
               definitely fixed for the expiration of the term and the Tenant
               will then quit and surrender the surrender the demised premises
TEN DAY        to the Landlord, but the Tenant shall remain liable as
NOTICE         hereinafter provided.

REPOSSESSION               If the Tenant shall make default in the payment of
                      the rent hereunder, or any item of "additional rent"
                      herein mentioned or any part of either or in making any
                      other payment herein provided for, or if the notice last
                      above provided for shall have been given and if the
                      condition which was the basis of said notice shall exist
                      at the expiration of said ten days' period, the Landlord
                      may immediately, or at any time thereafter, re-enter the
                      demised premises and remove all persons and all or any
                      property therefrom, either by summary disposses
                      proceedings, or by any suitable action or proceeding law, 
RE-LETTING            or by force  or otherwise, without being liable to
                      indictment, prosecution or damages therefor, and
                      re-possess and enjoy said premises together with all
                      additions, alterations and improvements. In any such
                      case or in the event that this lease be "terminated" 
                      before the commencement of the term, as above provided,
                      the Landlord may either re-let the demised premises or
                      any part or parts thereof for the Landlord's own account,
                      or may, at the Landlord's option, re-let the demised
                      premises or any part or parts thereof as the agent of
                      the Tenant, and receive the rents thereof, applying the
                      same first to the payment of such expenses as the
                      Landlord may have incurred, and then to the fulfillment
                      of the covenants of the Tenant herein, and the balance,
                      if any, at the expiration of the term first above
                      provided for, shall be paid to the Tenant. Landlord may
                      rent the premises for a term extending beyond the term
WAIVER                hereby granted without releasing Tenant from any 
BY TENANT             liability. In the event that the term of this lease
                      shall expire as above in this subdivision "Sixth"
                      provided, or terminate by summary proceedings or
                      otherwise, and if the Landlord shall not re-let the
                      demised premises for the Landlord's own account, then,
                      whether or not the premises be re-let, the Tenant shall
                      remain liable for, and the Tenant hereby agrees to pay
                      to the Landlord, until the time when this lease would
                      have expired but for such termination or expiration, the
                      equivalent of the amount of all of the rent and
                      "additional rent" reserved herein, less the avails of
                      reletting, if any, and the same shall be due and payable
                      by the Tenant to the Landlord on the several rent days 
                      above specified, that is, upon each of such rent days
                      the Tenant shall pay to the Landlord the amount of
                      deficiency then existing. The Tenant hereby expressly
                      waives any and all right of redemption in case the
                      Tenant shall be dispossessed by judgment or warrant
                      of any court or judge, and the Tenant waives and will
                      waive all right to trial  by jury in any summary
                      proceedings hereafter instituted by the Landlord against
                      the Tenant in respect to the demised premises. The words
                      "re-enter" and "re-entry" as used in this lease are not
                      restricted to their technical legal meaning.
        
                      In the event of a breach or threatened breach by the
                      Tenant of any of the covenants or provisions hereof, the
                      Landlord shall have the right of injunction and the right
REMEDIES ARE          to invoke any remedy allowed at law or in equity, as if
CUMULATIVE            re-entry, summary proceedings and other remedies were not
                      herein provided for.        


                           SEVENTH.--If the tenant shall make default in the
                      performance of any covenant herein contained, the Landlord
                      may immediately, or at any time thereafter, without
                      notice, perform the same for the account of the Tenant. If
LANDLORD              a notice of mechanic's lien be filed against the demised
MAY                   premises or against premises of which the demised premises
PERFORM               are part, for, or purporting to be for, labor or material
                      alleged to have been furnished, or to be furnished to or
                      for the Tenant at the demised premises, and if the Tenant
                      shall fail to take such action as shall cause such lien to
                      be discharged within fifteen days after the filing of such
                      notice, the Landlord may pay the amount of such lien or
                      discharge the same by deposit or by bonding proceedings,
                      and in the event of such deposit or bonding proceedings,
                      the Landlord may require the lienor to prosecute an
                      appropriate action to enforce the lienor's claim. In such
                      case, the Landlord may pay any judgment recovered on such
                      claim. Any amount paid or expense incurred by the Landlord
                      as in this subdivision of this lease provided, and any
                      amount as to which the Tenant shall at any time be in
                      default for or in respect to the use of water, electric
                      current or sprinkler supervisory service, and any expense
                      incurred or sum of money paid by the Landlord by reason of
                      the failure of the Tenant to comply with any provision
                      hereof, or in defending any such action, shall be deemed
ADDITIONAL            to be "additional rent" for the demised premises, and
RENT                  shall be due and payable by the Tenant to the Landlord on
                      the first day of the next following month, or, at the
                      option of the Landlord, on the first day of any succeeding
                      month. The receipt by the Landlord of any instalment of
                      the regular stipulated rent hereunder or any of said
                      "additional rent" shall not be a waiver of any other
                      "additional rent" then due.

                           EIGHT.--The failure of the Landlord to insist, in
                      any one or more instances upon a strict performance of
AS TO                 any of the covenants of this lease, or to exercise any
WAIVERS               option herein contained, shall not be construed as a
                      waiver or a relinquishment for the future of such covenant
                      or option, but the same shall continue and remain in
                      full force and effect. The receipt by the Landlord of
                      rent, with knowledge of the breach of any covenant
                      hereof, shall not be deemed a waiver of such breach and
                      no waiver by the Landlord of any provision hereof shall
                      be deemed to have been made unless expressed in writing
                      and signed by the Landlord. Even though the Landlord
                      shall consent to an assignment hereof no further
                      assignment shall be made without express consent in
                      writing by the Landlord.           

                           NINTH.--If this lease be assigned, or if the demised
                      premises or any part thereof be underlet or occupied by
                      anybody other than the Tenant the Landlord may collect
                      rent from the assignee, under-tenant or occupant, and
COLLECTION            apply the net amount collected to the rent herein
OF RENT               reserved, and no such collection shall be deemed a waiver
FROM OTHERS           of the covenant herein against assignment and
                      underletting, or the acceptance of the assignee,
                      under-tenant or occupant as a tenant, or a release of the
                      Tenant from the further performance by the Tenant of the
                      covenants herein contained on the part of the Tenant.

        
                           TENTH.--This lease shall be subject and subordinate
                      at all times, to the lien of the mortgages now on the
                      demised premises, and to all advances made or hereafter
                      to be made upon the security thereof, and subject and
MORTGAGES             subordinate to the lien of any mortgage or mortgages which
                      at any time may be made a lien upon the premises. The 
                      Tenant will execute and deliver such further instrument or
                      instruments subordinating this lease to the lien of any
                      such mortgage or mortgages as shall be desired by any
                      mortgage or proposed mortgagee. The Tenant hereby
                      appoints the Landlord the attorney-in-fact of the
                      Tenant, irrevocable, to execute and deliver any such
                      instrument or instruments for the Tenant.
        

                           ELEVENTH.--All improvements made by the Tenant to or
                      upon the demised premises, except said trade fixtures,
                      shall when made, at once be deemed to be attached to the
                      freehold, and become the property of the Landlord, and at
IMPROVEMENTS          the end or other expiration of the term, shall be
                      surrendered to the Landlord in as good order and condition
                      as they were when installed, reasonable wear and damages
                      by the elements excepted.
                      
                           TWELFTH.--Any notice or demand which under the 
                      terms of this lease or under any statute must or may be
NOTICES               given or made by the parties hereto shall be in writing
                      and shall be given or made by mailing the same by
                      certified or registered mail addressed to the respective
                      parties at the addresses set forth in this lease.
        
                        
                           THIRTEENTH.--The landlord shall not be liable for any
                      failure of water supply or electrical current, sprinkler
                      damage, or failure of sprinkler service, nor for injury or
                      damage to person or property caused by the elements or by
NO LIABILITY          other tenants or persons in said building, or resulting
                      from steam, gas, electricity, water, rain or snow, which
                      may leak or flow from any part of said buildings, or from
                      the pipes, appliances or plumbing works of the same, or
                      from the street or sub-surface, or from any other place,
                      nor for interference with light or other incorporeal
                      hereditaments by anybody other than the Landlord, or
                      caused by operations by or for a governmental authority in
                      construction of any public or quasi-public work, neither
                      shall the Landlord be liable for any latent defect in the
                      building.
        

                      FOURTEENTH.--No diminution or abatement of rent, or other
                      compensation shall be claimed or allowed for inconvenience
                      or discomfort arising from the making of repairs or
NO                    improvements to the building or to its appliances, nor for
ABATEMENT             any space taken to comply with any law, ordinance or order
                      of a governmental authority. In respect to the various
                      "services," if any, herein expressly or impliedly agreed
                      to be furnished by the Landlord to the Tenant, it is
                      agreed that there shall be diminution or abatement of the
                      rent, or any other compensation, for interruption or
                      curtailment of such "service" when such interruption or
                      curtailment shall be due to accident, alterations or 
                      repairs desirable or necessary to be made or to
                      inability or difficulty in securing supplies or labor
                      for the maintenance of such "service" or to some other
                      cause, not gross negligence on the part of the Landlord.
                      No such interruption or curtailment of any such "service"
                      shall be deemed a constructive eviction. The Landlord
                      shall not be required to furnish, and the Tenant shall
                      not be entitled to receive, any of such "services" during
                      any period wherein the Tenant shall be in default in
                      respect to the payment of rent. Neither shall there be any
                      abatement or diminution of rent because of making of
                      repairs, improvements or decorations to the demised
                      premises after the date above fixed for the commencement

      FLOOR     of any part thereof, the Tenant will keep the sidewalk and curb in front thereof clean at all times and free from
                snow and ice, and will keep insured in favor of the Landlord, all plate glass therein and furnish the Landlord
                with policies of insurance covering the same.

                        TWENTY-THIRD. -- If by reason of the conduct upon the demised premises of a business not herein permitted,
   INCREASED    or if by reason of the improper or careless conduct of any business upon or use of the demised premises, the fire
        FIRE    insurance rate shall at any time be higher than it otherwise would be, then the Tenant will reimburse the Landlord,
   INSURANCE    as additional rent hereunder, for that part of all fire insurance premiums hereafter paid out by the Landlord which
        RATE    shall have been charged because of the conduct of such business not so permitted, or because of the improper or
                careless conduct of any business upon or use of the demised premises, and will make such reimbursement upon the
                first day of the month following such outlay by the Landlord; but this covenant shall not apply to a premium for
                any period beyond the expiration date of this lease, first above specified. In any action or proceeding wherein
                the Landlord and Tenant are parties, a schedule or "make up" of rate for the building on the demised premises,
                purporting to have been issued by New York Fire Insurance Exchange, or other body making fire insurance rates for
                the demised premises, shall be prima facie evidence of the facts therein stated and of the several items and

                        TWENTY-FOURTH. -- If a separate water meter be installed for the demised premises, or any part thereof, the
 WATER RENT     Tenant will keep the same in repair and pay the charges made by the municipality or water supply company for or in

                thereof, be supplied with water through a meter which supplies other premises, the Tenant will pay to the Landlord,
                as and when bills are rendered therefor, the Tenant's proportionate part of all charges which the municipality or 
                water supply company shall make for all water consumed through said meter, as indicated by said meter. Such
                proportionate part shall be fixed by apportioning the respective charge according to floor area against all of the
                rentable floor area in the building (exclusive of the basement) which shall have been occupied during the period
                of the respective charges, taking into account the period that each part of such area was occupied. Tenant agrees   
      SEWER     of pay as additional rent the Tenant's proportionate part, determined as aforesaid, of the sewer rent or charge
                imposed or assessed upon the building of which the premises are a part.                                            

   ELECTRIC             TWENTY-FIFTH. -- That the Tenant will purchase from the Landlord, if the Landlord shall so desire, all
    CURRENT     electric current that the Tenant requires at the demised premises, and will pay the Landlord for the same, as the
                amount of consumption shall be indicated by the meter furnished therefor. The price for said current shall be the
                same as that charged for consumption similar to that of the Tenant by the company supplying electricity in the same
                community. Payments shall be due as and when bills shall be rendered. The Tenant shall comply with like rules,
                regulations and contract provisions as those prescribed by said company for a consumption similar to that of the
                Tenant.

                        TWENTY-SIXTH. -- If there now is or shall be installed in said building a "sprinkler system" the Tenant
                agrees to keep the appliances thereto in the demised premises in repair and good working condition, and if the
 SPRINKLER      New York Board of Fire Underwriters or the New York Fire Insurance Exchange or any bureau, department or official
    SYSTEM      of the State or local government requires or recommends that any changes, modifications, alterations or additional
                sprinkler heads or other equipment be made or supplied by reason of the Tenant's business, or the location of
                partitions, trade fixtures, or other contents of the demised premises, or if such changes, modifications,
                alterations, additional sprinkler heads or other equipment in the demised premises are necessary to prevent the
                imposition of a penalty or charge against the full allowance for a sprinkler system in the fire insurance rate as
                fixed by said Exchange, or by any Fire Insurance Company, the Tenant will at the Tenant's own expense, promptly
                make and supply such changes, modifications, alterations, additional sprinkler heads or other equipment. As
                additional rent hereunder the Tenant will pay to the Landlord, annually in advance, throughout the term

   NUISANCE     that the Tenant will conduct his business in such a manner, both as regards noise and kindred nuisances, as
                will in no wise interfere with, annoy, or disturb any other tenants, in the conduct of their several businesses,
                or the landlord in the management of the building; under penalty of forfeiture of this lease and consequential

                with the rules and commission rates of the Real Estate Board in the community. A sale, transfer, or other
                disposition of the Landlord's interest in said lease shall not operate to defeat the Landlord's obligation to
                pay the said commission to the said broker. The Tenant herein hereby represents to the Landlord that the said

        RIDER TO LEASE dated              ,1995 between 40 MARCUS REALTY
ASSOCIATES, as Landlord, and MANCHESTER EQUIPMENT CO., INC., as Tenant.

        1. Anything herein, to the contrary notwithstanding, Tenants shall, at
Tenants' own cost and expense, secure and pay for all interior repairs,
replacements, utilities, maintenance and services required by Tenants or for
preservation of the demised premises, including, but not limited to: gas,
electricity, telephone, light, janitorial services, plumbing, wiring, carpentry,
mechanical, plate glass, electrical, air-conditioning, store front, painting,
decorating and maintenance services, heat, fuel, garbage and waste disposal,
snow removal, water, hot water and sewer rent. Any fees or deposits for permits
or licenses for machinery, meters, signs or any other equipment or usage, shall
be made, secured, and/or paid for by Tenants at Tenants' own cost and expense.
Except as expressly provided in this Lease, Landlord shall have no obligation to
furnish or perform interior repairs, maintenance or services; provided however,
that Landlord shall be responsible for so-called "structural" repairs, defined
as exterior walls, structural members and foundation. As designated in the
within paragraph, "utilities" refers solely to those utilities consumed by the
within Tenant; i.e. the within Tenant shall have no responsibility for the
utilities consumed by other Tenants in the building in which the demised
premises are located.

        2. Anything herein to the contrary notwithstanding, Tenants are hereby
given permission to erect any sign or signs in and about the demised premises at
Tenant's own cost and expense, provided: (a) Any such sign shall comply with all
rules and regulations of any governmental authority having jurisdiction thereof;
(b) Said sign or signs shall be installed without damage to Landlord's building
including signs on each exterior wall; (c) Upon the removal of any such signs,
all damage occasioned thereby shall be repaired by Tenants at Tenants' own cost
and expense.

        3. Tenants shall secure, pay for and maintain during the term of this
Lease, a policy of general liability insurance, (having limits:
$1,000,000/2,000,000 for bodily injury; $100,000 for property damage) from a
financially responsible insurer licensed to do business in the State of New
York; which said policy shall name as protected, the Tenants and Landlord as the
fee owner, as their respective interests shall appear, and any other parties
designated by Tenants, and shall contain a waiver of subrogation as against the
Landlord as fee owner. Tenants shall deliver to the Landlord a certificate of
such insurance policy on or before the beginning of the term of this Lease. In
any such policy, the bodily injury coverage shall be written on an "Occurrence"
basis and shall include personal injury coverage; and shall also provide that no
modification, termination or cancellation thereof shall be effective until after
ten (10) days prior written notice has been given to Landlord by the insurance
carrier, to be forwarded by Certified or Registered Mail, Return Receipt
Requested. In the event of the failure of the Tenant

                                      {1}
<PAGE>   6
to secure, maintain and pay for such policy and to provide a certificate thereof
to Landlord, Landlord may, in Landlord's sole discretion, order such policy and
the premium cost thereof shall be due from Tenant as additional rent hereunder
or Landlord may elect to treat such failure as a default hereunder, in which
case, Tenant agrees such default is a material default of the Lease.

        4. Tenant, at its cost, shall maintain a policy of standard fire and
extended coverage insurance with vandalism and malicious mischief endorsements
to the extent of at least eighty [80%] percent of full replacement value as to
the demised structure and its environs, defined as follows: $850,000.00. The
insurance policy shall be issued in the name of Landlord, Tenant and Landlord's
lender, if any, now or in the future, as their interests appear. The insurance
policy shall provide that any proceeds shall be made payable to the Landlord or
Landlord's lender, as Landlord may designate. The Tenant agrees to assign and
deliver at the commencement of this Lease said insurance policy to the Landlord
and the said policy and renewal thereof shall be held by said Landlord. In the
event the Tenants do not pay the premiums as they fall due on said policy,
Landlord shall have the option of paying said premiums on behalf of Tenants, and
adding the cost thereof to the next month's rent due Landlord under the terms of
this Lease as additional rent and to collect same as "additional rent".

        The foregoing insurance policy shall provide that no modification,
termination or cancellation thereof shall be effective until after thirty [30]
days prior written notice has been given to the Landlord by the insurance
carrier, certified mail, return receipt.

        If any extraordinary or excessive insurance premium cost is charged to
Landlord as the result of the nature of Tenant's business, or its use and
occupancy of the demised premises or an installation, condition or alteration
made or maintained by Tenant therein, the full cost of such excess premium or
extraordinary charge shall be borne by and paid by Tenant. The finding or
"make-up" of rate established by the New York Fire Rating Organization [or such
other agency having jurisdiction and responsibility for rating the building for
insurance purposes] shall be admissible as evidence in any action and proceeding
and shall be deemed conclusive evidence of the facts therein stated and of the
items and charges then applicable to the building and the demised premises
located therein. The total costs of insurance and the totality of coverage shall
not exceed that which is reasonable and customary.

        5. The Tenants agree to indemnify the Landlord, as fee owner, and the
respective officers, directors, agents, servants and employees thereof against
and to defend, save and hold them harmless of and from, any and all liability,
cost and damage for or arising by reason of any and all claims, suits or causes
of action for bodily injury, personal injury, death or property damage to any
and all persons in any manner caused

                                      {2}
<PAGE>   7
by acts, negligence or omissions of, or any condition created, caused, permitted
or suffered by, the Tenants, its officers, directors, agents, servants, and
employees.

        6. Except for injury, loss or damage occasioned directly and
specifically as the result of the Landlord's negligence, the Landlord shall not
be liable or responsible to the Tenants for the safekeeping of any goods or
other property of the Tenant, nor for injury to any person or persons or any
damage to or loss of merchandise or other property of the Tenants occasioned by
theft, fire, water, power failure, accident or the bursting, leaking or running
in the demised premises of any plumbing, heating, electrical apparatus, gas,
steam or pipes of any nature, or from any other cause whatsoever; and except for
injury, loss or damage due to Landlord's negligence, anything herein to the
contrary notwithstanding, the Tenant, for itself and its insurers, releases
Landlord of and from any and all such liability and responsibility.

        7. It is understood and agreed that under any and all circumstances, the
liability of the Landlord shall not be personal and whenever Tenants, their
agents, servants or employees seek or recover any money judgment or other award
of damages against the Landlord from any Court, administrative body or tribunal
of competent jurisdiction, that satisfaction thereof shall be solely and
expressly limited to levy of execution against and collection out of the
interest of the Landlord in and to the demised premises and/or the land and
building of which the demised premises forms a part, and the Tenants for
themselves, their agents, servant and employees, heirs, successors and assigns,
expressly and specifically relinquishes, waives and releases any and all rights
to seek, secure, recover or collect any portion of such judgment, damages or
award against or from the Landlord personally or from any other property, assets
or estate of the Landlord, its heirs, successors, officers, directors,
shareholders, legal representatives, agents, servant, employees or assigns.

        8. In lieu of the Landlord not requiring the Tenant to maintain a policy
of plate glass insurance, it is specifically agreed that the Tenant shall be
solely responsible for the replacement of any and all plate glass damage at the
Tenant's cost and expense. In the event the Tenant fails to replace and or
repair plate glass within a reasonable time after damage thereto, the Landlord
shall have the right to repair said plate glass damage, and in such event, the
landlord is hereby authorized to add the cost of such repair to any regular
installment of rent thereafter becoming due, as additional rent.

         9. Tenants shall bear and pay to the Landlord as additional rent during
each Lease year, the cost to Landlord of the following:

                  A. Commencing with the rental due November 1, 1995, the fixed
annual rent hereinbefore set forth for each fiscal year of this Lease
(hereinafter a "lease year") shall be increased by additional rental in an
amount equal to one hundred [100%] percent of the amount expended for taxes, [as
hereinafter defined], in such Lease year.

                                      {3}
<PAGE>   8
                  FOR INFORMATION PURPOSES ONLY: The 1994/95
                  tax bill for the demised premises is in the
                  amount of $31,515.48.

        Such additional rental shall be paid by the Tenants within fifteen (15)
days after the Landlord shall have served upon Tenants a written statement
thereof. The Tenants or their authorized representative shall have the right to
inspect the books of the Landlord during its regular business hours for the
purpose of verifying the information set forth in the statement submitted by the
Landlord pursuant to this paragraph provided that written request for such
inspection shall be made by the Tenants within ten (10) days after the receipt
of such statement. For purposes of this paragraph, the term "Taxes" means real
estate taxes, transfer taxes, vault charges and other governmental taxes or
charges, special, ordinary or extraordinary, foreseen or unforeseen (but not
income, franchise, inheritance or capital stock taxes) which may now or
hereafter be levied or assessed against the lands and buildings of which the
demised premises form a part thereof. In the event the tax year does not
correspond with a Lease year, equitable proration shall be made in determining
the amount expended in respect of such period.

        (a) Every "lease year" during the term hereof shall be for a period of
twelve (12) full calendar months, except that the last Lease year shall
terminate on the date this Lease expires or is otherwise terminated.

        (b) In the event that as the result of changes in the laws, enabling
statutes or other code, rules or regulations, including but not limited to the
Internal Revenue Code, taxes or other levies or assessments against gross rental
income shall be substituted in whole or in part for any real property taxes or
assessments presently applicable to real property, then and to the extent that
such taxes shall be and constitute a substitute for the real property taxes
against the premises of which the demised premises forms a part, such substitute
tax or assessment shall be included in and considered part of the real property
taxes for the purposes of calculating the portion thereof to be paid by Tenants
as additional rent hereunder.

         10. A. The amount of all such additional rent shall be due and payable
with the next regular monthly installment of rent following the submission to
Tenants of a bill, together with the calculation of additional rent due,
therefor by Landlord.

         B. A copy of the official tax bill, insurance premium bill or other
statement or invoice for a charge or expense to Landlord shall be deemed
sufficient and

                                      {4}
<PAGE>   9
conclusive evidence of the amount of such charge or expense, a percentage of
which is payable by Tenant to Landlord as additional rent.

        C. If any extraordinary or excessive insurance premium cost is charged
to Landlord as the result of the nature of Tenant's business, or its use and
occupancy of the demised premises or an installation, condition or alteration
made or maintained by Tenant therein, the full cost of such excess premium or
extraordinary charge shall be borne by and paid by Tenants. The finding or
"make-up" of rate established by the New York Fire Rating Organization (or such
other agency having jurisdiction and responsibility for rating the building for
insurance purposes) shall be admissible as evidence in any action and proceeding
and shall be deemed conclusive evidence of the facts therein stated and of the
items and charges then applicable to the building and the demised premises
located therein. The total costs of insurance and the totality of coverage shall
not exceed that which is reasonable and customary.

        D. The portion of the Landlord's costs or charges payable as additional
rent by Tenants shall be apportioned on the basis that the first Lease year, the
last Lease year or any Lease year does not coincide with the fiscal year to
which any such charge is applicable.

        11. It is specifically agreed that in the event of the default by
Tenants in the performance of this Lease or the payment when due of any
installment of rent or additional rent or any other sum due under this Lease,
the Landlord is expressly authorized, empowered, directed and entitled to use,
apply or retain as Landlord's sole property that portion or all of the security
deposited by Tenants on the signing of this Lease to the extent necessary to
cure such default or to reimburse Landlord for any sum which he may expend or be
required to expend by reason of Tenant's default. All or any portion of the said
security deposit thus used or applied by Landlord shall be made up and
redeposited by Tenants forthwith on demand to the original amount of the
security deposit required under this Lease. The security deposit to be made
hereunder and any additions thereto, shall be deposited by the Landlord in a
separate interest bearing savings account, and all interest accruing thereon
shall be deemed as additional security, and held by the Landlord pursuant to the
security provisions of the within Lease.

        12. Tenants agree that if Landlord shall pay or be compelled to pay a
sum of money or to perform any act that requires the payment of money, by reason
of the failure of the Tenant to keep, observe, or perform any of the terms,
covenants and provisions herein contained to be kept, observed or performed by
the Tenants, other than the payment of rent, then and in such event, the sum or
sums so paid by the Landlord shall, upon Landlord's demand, be paid by Tenants
to Landlord as additional rent, with interest thereon at the maximum rate of
interest allowable on the date of such

                                      {5}
<PAGE>   10
demand, together with the installment of the monthly base rent next due from
date of said demand.

        13. Any and all notices, consents and other communications which either
party may desire or be required to give to the other shall be in writing and,
except as otherwise herein specifically provided, shall be sent by Certified
Mail, Return Receipt Requested, addressed to the party for whom intended at the
address first herein above set forth or at such other address as such party may
designate for such purpose by notice duly given to the other. All such notices
shall be deemed to have been duly given on the third business day following the
date of the deposit thereof, securely enclosed in a postpaid wrapper addressed
as above, in an official depository maintained for mailing purposes by the U. S.
Post Office Department (or its successor postal agency).

        14. If any term, condition or provision of the printed portion of this
Lease shall be inconsistent with a provision of this Rider, then the
inconsistent portions of the printed Lease form shall be deemed superseded by
the provisions set forth in this Rider. Wherever appropriate for good usage or
meaningful interpretation, terms expressed in the neuter, masculine or feminine
gender shall be deemed interchangeable, as shall terms expressed in the singular
or plural be deemed interchangeable.

        15. In the event that any payment provided to be made hereunder shall
become overdue in excess of ten (10) days as additional rent, Tenant shall pay
to the Landlord a late charge of five (.05) cents for each dollar so overdue to
compensate Landlord for expenses incurred in handling such delinquent payment or
payments. The charges hereunder shall be due and owing regardless of application
of security pursuant to paragraph "10".

        16. On the written request of either party, the Landlord and the Tenants
each covenant and agree to execute, seal, acknowledge and deliver unto the
other, within ten (10) days of written request, a certificate attesting: (a)
Whether this Lease is current and in full and continuing force and effect; (b)
Whether there are any defaults, arrears, set-offs, claims, counter-claims or
defenses to or against the full enforcement of any of the terms, covenants and
conditions to be paid and performed hereunder; (c) To the amount of the rent
then being paid and the dates of the commencement and expiration of the term
hereof; (d) To the period for which and the amount of the rent which has then
been prepaid; and (e) Whether the other party has fully performed all
obligations on its part to be performed.

        17. It is specifically understood and agreed that any item required to
be paid by Tenants, including additional rent or payments for defaults, shall be
deemed rent, and upon the failure of Tenants to pay the same when due, it shall
be deemed equivalent

                                      {6}
<PAGE>   11
to a default in the payment of rent and shall entitle Landlord to invoke any and
all remedies as in the case of non-payment of rent.

         18. In any case where Landlord brings any action or summary proceeding
for any default of the Tenants hereunder, whether for the non-payment of rent or
additional rent or any other default, Landlord shall be entitled to reasonable
attorney's fees if successful; plus filing fees, sheriff's fees, if any, for any
one action or proceeding. Parties each waive trial by jury in any summary
proceeding.

         19. The Tenants shall have the right to contest any real estate tax,
special assessments or other governmental charges levied against the real
property of which the demised premises are a part, by writ of certiorari, or
otherwise, in the same manner as provided by law for the owner of the property
to contest the same upon condition that the Tenants shall pay, immediately upon
billing, such real estate taxes, special assessments or other government charges
(looking to the taxing authorities for a refund thereafter), and upon the
further condition that the cost of such proceeding shall be borne solely by the
Tenants and the Tenants shall hold the Landlord free and harmless from any cost,
penalties, interest, damages or other liability otherwise incurred as the result
thereof. Landlord shall, at Tenant's request, execute such documents as are
reasonably necessary to carry out the foregoing. in the event the Tenant should
be successful in contesting as aforesaid, the result of which creates a refund
to the landlord, the following shall apply:

         Upon receipt by the Landlord of such refund, the Landlord shall return
to the Tenant the costs and expenses incurred by the Tenant in obtaining such
refund. The Tenants shall have a similar right to contest insurance costs and
any other costs charged pursuant to paragraphs "8" and "9".

         20. Ceiling lighting fixtures shall not be deemed trade fixtures, and
upon installation, the same shall become, be and remain Landlord's sole
property. All light bulbs, tubes, ballasts, starters, switches, lenses and
grills for such ceiling fixtures, and the servicing and maintenance thereof
shall at all times be solely the obligation of Tenant.

         21. A. Tenant covenants and agrees that it will occupy the entire
demised premises, and will conduct its business in the regular and usual manner,
throughout the term of this Lease. Tenants acknowledge that Landlord is
executing this Lease in reliance upon these covenants, and that these covenants
are a material element of consideration inducing the Landlord to execute this
Lease. Tenant further agrees that if it vacates the demised premises or fails to
so conduct its business therein, at any time during the term of this Lease,
without the prior written consent of the Landlord, then all

                                      {7}
<PAGE>   12
rent and additional rent reserved in this Lease from the date of such breach to
the expiration date of this Lease. shall become immediately due and payable to
Landlord.

        B. The parties recognize and agree that the damage to Landlord resulting
from any breach of the covenants in subdivision (a) hereof will be substantial
and will be greater than the rent payable for the balance of the term of this
Lease, and will be impossible of ascertainment. The parties, therefore, agree as
follows;

                1. In the event of a breach or threatened breach of the said
covenants, in addition to all of Landlord's other rights and remedies, at law or
in equity or otherwise, Landlord shall have the right of injunction to preserve
Tenant's occupancy and use. The words "become vacant or deserted" as used
elsewhere in this Lease shall include Tenant's failure to occupy or use as by
this Article required.

                2. If Tenants breach either of the covenants in subdivision (a)
above, and this Lease be terminated because of such default, then, anything in
this Lease as to the contrary notwithstanding:

                            (a) Landlord shall have the right to re-enter the
demised premises, and to alter, reconstruct and rent all or any part of the
premises, at any rental to which Landlord shall agree, for any portion of or
beyond the original term of this Lease.

                            (b) Any income received by Landlord on any such
re-rental shall be the property of the Landlord alone, as compensation for the
expenses in connection with the preparation and re-renting of the demised space,
and, together with the rents and additional rents payable as aforesaid, as
liquidated damages for the breach of Tenants, which damages cannot be computed,
as aforesaid. Tenants shall have no right to any portion of such income.

        22. In any action or summary proceeding brought by Landlord against
Tenants under this Lease (or any renewal, extension, holdover or modification
thereof), for non-payment of rent or additional rent, the Tenant hereby waives
the right to interpose, and expressly covenants and agrees not to interpose, any
counterclaim or set-off of whatever nature or description. The foregoing,
however, shall not be deemed or constitute a waiver of the Tenant's right to
commence and prosecute a separate action against Landlord on a bona-fide claim.

        23. Every "Lease Year" during the term hereof shall be for a period of
twelve (12) full calendar months, except that the last Lease year shall
terminate on the date this Lease expires or is otherwise terminated.

                                      {8}
<PAGE>   13
        24. The fixed annual rent hereinafter provided is intended to be and
shall be absolutely net to Landlord. It is the intention of the parties hereto
that all expenses, costs and obligations of the parties hereto, all expenses,
costs and obligations of every kind and nature whatsoever relating to the
demised premises, (with the exception of the base real estate taxes and
structural repairs as defined herein), shall be paid by Tenants either directly
or as additional rent so that this Lease shall yield to Landlord the net fixed
annual rent specified during the term of this Lease.

        25. If any term or provision of this Lease or the application thereof to
any person or circumstances shall, to any extent, be invalid or unenforceable,
the remainder of this Lease, or the application of such term or provision to
persons or circumstances other than those as to which it is held invalid or
unenforceable, shall not be affected thereby, and each term and provision of
this Lease shall be valid and be enforced to the fullest extent permitted by
law.

        26. Tenants agree not to allow or permit during the demised term, any
mechanic's or other lien for work, labor and services and/or materials furnished
or otherwise to attach to and become a lien upon the premises as a result of any
work done by or on behalf of Tenants. If such lien shall so attach, Tenants
shall within thirty (30) days after notice thereof, either pay or satisfy the
same or procure the discharge thereof of record in such manner as may be
permitted or provided by law. Should Tenants fail or refuse to discharge any
such lien within the period herein provided, then Landlord is hereby authorized
to add the amount of the said lien to any regular installment of rent thereafter
becoming due as additional rent.

        27. During the entire term of this Lease, the Tenants shall be required
to keep in full force and effect all necessary Certificates of Occupancy for the
purposes for which the demised premises are rented, permits and other approvals
or consents required by any governmental authority having jurisdiction over the
business conducted by the Tenants as set forth in the purpose clause of this
Lease. The Landlord represents that the present zoning of the demised premises
is "C8".

        28. Should any conflict in language or interpretation occur between the
printed provisions of this Lease, the parties agree that the provisions in the
Rider shall prevail. All reference to paragraphs as set forth in the Rider shall
refer to paragraphs so indicated in the Rider and not to paragraphs in the
printed portion of this Lease, unless so designated or unless the context of the
Rider is intended to designate the printed portion of this Lease.

         29. This Lease contains all of the agreements and understandings of the
parties and cannot be amended or modified except by a written agreement.

                                      {9}
<PAGE>   14
         30. The unenforceability, invalidity or illegality of any provision of
the Lease shall not render the other provisions unenforceable, invalid or
illegal.

         31. This Lease shall not be recorded. No Memorandum shall be recorded
without the express written consent of the Landlord.

         32. Tenants covenant that the demised premises will not be used so as
to interfere with other Tenants in the same building.

         33. In the event the Tenants do not vacate the premises upon the
expiration date of this Lease, then and in that event, the Tenants shall remain
as month to month Tenants at a monthly rental 100% greater than the last monthly
rental paid during the term of the Lease. Nothing herein shall grant the Tenants
a right to holdover after the expiration of the Lease term.

         34. The annual base rent for the years of the term of the within Lease
shall be as follows:

                                     Annual

Nov. 1, 1995 to Oct. 31, 1996     $288,000.00 - monthly $24,000.00,
Nov. 1, 1996 to Oct. 31, 1997     $302,400.00 - monthly $25,200.00,
Nov. 1, 1997 to Oct. 31, 1998     $317,520.00 - monthly $26,460.00,

        (f) If Tenants are a corporation, any dissolution, merger, consolidation

herein; provided, however, that transfers of capital stock of the Tenant between
presently existing shareholders of the Tenant, or transfers of capital stock to
members of the immediate family of the present shareholders of the Tenant, shall

        (g) If the Tenants are a corporation, or this Lease is subsequently

recited herein in Lease paragraph "27". This provision shall apply to each and
every assignment or sub-Lease of the within Lease.

        36. Defaults and remedies. A. If (1) Tenants default in the payment of
any rent or any additional rent and such default continues for five (5) days
after written notice from Landlord or its agent or (2) Tenant defaults in
fulfilling any of the covenant or agreements or any rules or regulations of this
Lease on its part to be kept or performed and such default is not made good
within ten (10) days after written notice from Landlord or its agent, or within
such additional time as Tenant may be prevented from making good the default as
is caused by delays attributable to strikes, labor troubles, acts of God,
governmental prohibitions and similar causes beyond Tenant's control, or (3) If
this Lease is transferred to or devolve upon any person or corporation other
than Tenant, except as may be specifically permitted by this Lease, or if this
Lease is mortgaged or assigned without the written consent of the Landlord, then
and in any of such events mentioned in this subparagraph "A" the term thereof,
shall thereupon ipso facto expire and come to an end as if such expiration was
so fixed by the terms of this Lease on the fifth (5th) or tenth (10th) day of
such default as mentioned in (1) and (2) above and upon the occurrence mentioned
in (3) above and Landlord may re-enter upon the demised premises either with or
without process of law and remove all persons therefrom and Tenant shall quit
and surrender the same to Landlord and Tenants shall remain liable as
hereinafter provided. In the event Tenants shall fail, neglect or refuse to quit
and surrender the demised premises upon receipt of notice from Landlord
declaring the term hereof at an end, then Landlord may commence a summary
proceeding to remove Tenant from the premises as a holdover. If pursuant to (2)
the default is of such a nature that it cannot be cured within ten (10) days, if
Tenant commences to cure such default within ten (10) days and proceeds
diligently to remedy such default, the Landlord shall not have the right to
terminate this Lease.

        B. If Tenants shall abandon the demised premises or if the premises
become and remain vacant or deserted for a period of fifteen (15) days, or if
the term of this Lease shall expire as hereinabove provided, or if Tenant fails
to take possession of the demised premises within forty-five (45) days after
commencement of the term of this Lease, Landlord may re-enter the demised
premises and remove Tenant or its legal representatives or other occupant by
summary proceedings or otherwise and Tenant hereby waives the service of notice
of intention or to institute legal proceedings to that end.

        C. In case of any re-entry, expiration and/or dispossess by summary
proceedings or otherwise, the rent shall become due thereupon and be paid up to
the time of such re-entry, dispossess and/or expiration, together with such
expenses as Landlord may incur for legal expenses, attorneys fees, brokerage
and/or putting the demised premises in good order, or for preparing the same for
re-rental; Landlord may relet the premises or any part or parts thereof either
in the name of Landlord or

                                      {12}
<PAGE>   17
otherwise, for a term or terms which may at the Landlord's option be less than
or exceed the period which may otherwise have constituted the balance of the
term of this Lease and may grant reasonable concessions, or free rent; and
Tenant or the legal representatives of Tenant shall also pay Landlord as
liquidated damages for the failure of Tenant to observe and perform said
Tenant's covenants herein contained, and deficiency between all rent or
additional rent hereby reserved and/or covenanted to be paid, with percentage
rental computed for the balance of the term for the purpose of this article at
the average annual percentage rent for the two (2) full Lease years preceding
the default or re-entry and the net amount, if any, of the rents collected on
account of the Lease of the demised premises, for each month of the period which
would otherwise have constituted the balance of the terms of this Lease. In
computing such liquidated damages there shall be added to the said deficiency
such expenses as Landlord may incur in connection with reletting, such as
reasonable legal expenses, attorneys fees, brokerage and for keeping the demised
premises in good order or for preparing the same for reletting. Any such
liquidated damages shall be paid in monthly installments by Tenant on the rent
days specified in this Lease. Any suit brought to collect the amount of the
deficiency for any month shall not prejudice in any way the rights of Landlord
to collect the deficiency for any subsequent month by a similar proceeding.
Landlord at Landlord's option may make such alterations, repairs, replacements
and/or decorations in the demised premises; and the making of such alterations,
repairs, replacement and/or decorations shall not operate or be construed to
release Tenant from liability hereunder as aforesaid. Landlord shall not be
liable for failure to relet the demised premises. The words "re-enter" or
"re-entry" as used in this Lease shall not be restricted to their technical
legal meaning. Any rents or other income received by Landlord on any such
re-rental shall be the property of Landlord alone and Tenant shall have no right
to any portion of such income. In the event that the Tenant is successful in any
proceeding brought pursuant to the provisions hereof, it shall be entitled to
its reasonable legal fees.

        D. In the event of a breach or threatened breach by Tenants of any of
the covenants or provisions of this Lease, Landlord shall have the right of
injunction and the right to invoke any remedy allowed at law or equity as if
re-entry, summary proceedings and other remedies were not herein provided for.
Mention in this Lease of any particular remedy shall not preclude Landlord from
any other remedy, in law or in equity. Tenants hereby expressly waive any and
all rights of redemption granted by order or any present or future laws in the
event of Tenants being evicted or dispossessed, or in the event of Landlord
obtaining possession of the demised premises by reason of Tenant's violation of
the provisions of this Lease. Tenants further waive the provisions of Section 
749, Subparagraph 3 of the Real Property Actions and Proceedings Law and any
successor statute thereto.

         E. In the event Tenants shall default in the payment of any rent or
additional rent as above provided, and such default shall continue for ten (10)
days after written

                                      {13}
<PAGE>   18
notice from Landlord, or its agent and not be made good within said ten (10) day
period, then and in such event, Landlord may, at its election, and in addition
to any other remedy herein afforded, declare this term at an end and accelerate
the rent due for the entire Lease period. In such event, the balance of the
minimum rent reserved from the date of such default until the last day of the
Lease period, shall thereupon be forthwith due and payable. Failure by Landlord
to relet the premises shall not be deemed an offset or defense to recovery of
the aforesaid minimum rent due for the balance of the term accelerated by reason
of Tenant's default above mentioned. Landlord shall be required to give the
notice provisions contained in paragraph "12" hereof.

        F. If Tenants shall default in the performance of any provision,
covenant or condition on its part to be performed under this Lease, Landlord
may, at its option, perform the same for the account and at the expense of
Tenants. If Landlord at any time shall be compelled to pay or elected to pay any
sum of money by reason of the failure of the Tenant to comply with any provision
of this Lease, or if Landlord incurs any expense, including reasonable
attorney's fees in prosecuting or defending any action or proceeding by reason
of any default of Tenant under this Lease, the sums so paid by Landlord with
legal interest, costs, and damages shall be due from and be paid by Tenant to
Landlord on demand. All such sums, including all payments required to be made by
Tenants of any kind under this Lease, shall be deemed additional rent and
Landlord shall have all remedies for the collection thereof that Landlord may
have for non-payment of minimum rent. In the event that the Tenants are
successful in any proceedings brought pursuant to the provisions hereof, it
shall be entitled to its reasonable legal fees and costs.

        37. The Tenants represent, warrant and declare that they have been
afforded the opportunity to make exterior and interior inspection of the
premises which are the subject of this Lease, that they have either made such
inspection of the said premises, or has caused such inspection of the said
premises to be made, and the Tenants distinctly understand that the premises are
being leased in their present condition and state of repair, and tenants agree
that at the time of closing Tenants will accept the premises in their present
condition and state of repair.

        38. Prior to the commencement of any alterations contemplated by the
Tenants during the term of this Lease, the Tenants shall furnish written plans
and specifications therefor to the Landlord and obtain the Landlord's written
consent thereto, which consent will not be unreasonably withheld.

                  (a) The Tenants will apply for and obtain any and all permits
therefor as same may be required by any municipal agency or authority having
jurisdiction, prior to the commencement of such alterations, and will apply for
and secure any and all requisite certificates of occupancy or certificates of
completion therefor.

                                      {14}
<PAGE>   19
                  (b) The Landlord and Tenant acknowledge that the Tenant
contemplates causing extensive alterations and renovations to the demised
premises, at the Tenants' sole cost and expense.

                  The Tenant shall notify the Landlord upon the completion of
the foregoing alterations and renovations. Upon inspection by the Landlord that
same have been performed in a workmanlike and satisfactory manner, and of all
requisite permits, completion certificates and/or Certificates of Occupancy, are
to be furnished to the Landlord.

        39. Tenant represents and warrants that Tenant did not consult with any
broker with regard to this transaction, and the Tenant agrees to indemnify and
save harmless the Landlord of any and all liability, expense, loss, cost or
damage that may arise by reason of any brokerage claims or demands by reason of
Tenant's acts, and makes this covenant as an express inducement to the Landlord,
intending that Landlord shall rely thereon entering into this Lease. This
covenant and representation is irrevocable, and shall survive the execution of
the within Lease.

        40. If any provision of this Rider shall be in conflict with any
provision of the printed form of this lease, the provisions of this Rider shall
control.

                building; will not permit the accumulation of waste or refuse

CONDITIONING    apparatus shall be installed or used without the prior written
                consent of Landlord.

                        IT IS MUTUALLY COVENANTED AND AGREED, THAT

                        FOURTH.--If the demised premises shall be partially
                damaged by fire or other cause without the fault or neglect of
                Tenant, Tenant's servants, employees, agents, visitors or
                licensees, the damages shall be repaired by and at the expense
                of Landlord and the rent until such repairs shall be made shall
                be apportioned according to the part of the demised premises
                which is usable by Tenant. But if such partial damage is due to
                the fault or neglect of Tenant, Tenant's servants, employees,
                agents, visitors or licensees, without prejudice to any other
FIRE CLAUSE     rights and remedies of Landlord and without prejudice to the
                rights of abrogation of Landlord's insurer, the damages shall
                be repaired by Landlord but there shall be no apportionment or
                abatement of rent. No penalty shall accrue for reasonable delay
                which may arise by reason of adjustment of insurance on the part
                of Landlord and/or Tenant, and for reasonable delay on account
                of "labor troubles", or any other cause beyond Landlord's
                control. If the demised premises are totally damaged or are
                rendered wholly untenantable by fire or other cause, and if
                Landlord shall decide not to restore or not to rebuild the same,
                or if the building shall be so damaged that Landlord shall
                decide to demolish it or to rebuild it, then or in any of such
                events Landlord may, within ninety (90) days after such fire or
                other cause, give tenant a notice in writing of such decision,
                which notice shall be given as in Paragraph Twelve hereof
                provided, and thereupon the term of this lease shall expire by
                lapse of time upon the third day after such notice is given, and
                Tenant shall vacate the demised premises and surrender the same
                to Landlord. If Tenant shall not be in default under this lease
                then, upon the termination of this lease under the conditions
                provided for in the sentence immediately preceding, Tenant's
                liability for rent shall cease as of the day following the
                casualty. Tenant hereby expressly waives the provisions of
                Section 227 of the Real Property Law and agrees that the
                foregoing provisions of this Article shall govern and control in
                lieu thereof. If the damage or destruction be due to the fault
                or neglect of Tenant the debris shall be removed by, and at the
                expense of, Tenant. 


                        FIFTH.--If the whole or any part of the premises hereby
                demised shall be taken or condemned by any competent authority
EMINENT         for any public use or purpose then the term hereby granted shall
DOMAIN          cease from the time when possession of the part so taken shall
                be required for such public purpose and without apportionment
                of award, the Tenant hereby assigning to the Landlord all right
                and claim to any such award, the current rent, however, in such
                case to be apportioned.

                        SIXTH.--If, before the commencement of the term, the
                Tenant be adjudicated a bankrupt, or make a "general
LEASE NOT       assignment," or take the benefit of any insolvent act, or if a
IN EFFECT       Receiver or Trustee be appointed for the Tenant's property, or
                if this lease or the estate of the Tenant hereunder be
                transferred or pass to or devolve upon any other person or
                corporation, or if the Tenant shall default in the performance
                of any agreement by the Tenant contained in any other lease to
                the Tenant by the Landlord or by any corporation of which an
                officer of the Landlord is a Director, this lease shall thereby,
                at the option of the Landlord, be terminated and in that case,
                neither the Tenant nor anybody claiming under the Tenant shall
                be entitled to go into possession of the demised premises, if
                after the commencement of the term, any of the events mentioned
                above in this subdivision shall occur, or if Tenant shall make
DEFAULTS        default in fulfilling any of the covenants of this lease, other
                than the covenants for the payment of rent or "additional rent"
                or if the demised premises become vacant or deserted, the
                Landlord may give to the Tenant ten days' notice of intention to
                end the term of this lease, and thereupon at the expiration of
                said ten days' (if said condition which was the basis of said
                notice shall continue to exist) the term under this lease shall
                expire as fully and completely as if that day were the date
                herein definitely fixed for the expiration of the term and the
                Tenant will then quit and surrender the demised premises to the
TEN DAY         Landlord, but the Tenant shall remain liable as hereinafter
NOTICE          provided.

POSSESSION     If the Tenant shall make default in the payment of the rent
LANDLORD       reserved hereunder, or any item of "additional rent" herein
               mentioned, or any part of either or in making any other payment
               herein provided for, or if the entire last above provided for
               shall have been given and if the condition which was the basis of
               said notice shall exist at the expiration of said ten days'
               period, the Landlord may immediately, or at any time thereafter,
               re-enter the demised premises and remove all persons and all or
               any otherwise, without being liable to indictment, prosecution or
               damages therefor, and re-possess and enjoy said premises together
               with all additions, alterations and improvements. In any such
               case or in the event that this lease be "terminated" before the
               commencement of the term, as above provided, the Landlord may
RE-LETTING     either re-let the demised premises or any part or parts thereof
               for the Landlord's own account, or may, at the Landlord's option,
               re-let the demised premises or any part or parts thereof as the
               agent of the Tenant, and receive the rents therefor, applying the
               same first to the payment of such expenses as the Landlord may

               the Tenant herein, and the balance, if any, at the expiration of
               the term first above provided for, shall be paid to the Tenant.
               Landlord may rent the premises for a term extending beyond the
               term hereby granted without releasing Tenant from any liability.
               In the event that the term of this lease shall expire as above in
WAIVER         this sub-division "Sixth" provided, or terminate by summary
BY TENANT      proceedings or otherwise, and if the Landlord shall not re-let
               the demised premises for the Landlord's own account, then,
               whether or not the premises be re-let, the Tenant shall remain
               liable for, and the Tenant hereby agrees to pay to the Landlord,
               until the time when this lease would have expired but for such
               termination or expiration, the equivalent of the amount of all of
               the rent and "additional rent" reserved herein, less the avails
               of reletting, if any, and the same shall be due and payable by
               the Tenant to the Landlord on the several rent days above
               specified, that is, upon each of such rent days the Tenant shall
               pay to the Landlord the amount of deficiency then existing. The
               Tenant hereby expressly waives any and all right of redemption in
               case the Tenant shall be dispossessed by judgment or warrant of
               any court or judge, and the Tenant waives and will waive all
               right to trial by jury in any summary proceedings hereafter
               instituted by the Landlord against the Tenant in respect to the
               demised premises. The words "re-enter" and "re-entry" as used in
               this lease are not restricted to their technical legal meaning.

REMEDIES ARE           In the event of a breach or threatened breach by the
ACCUMULATIVE   Tenant of any of the covenants or provisions hereof, the Landlord
               shall have the right of injunction and the right to invoke any
               remedy allowed at law or in equity, as if re-entry, summary
               proceedings and other remedies were not herein provided for.

                        SEVENTH. -- If the Tenant shall make default in the
               performance of any covenant herein contained, the Landlord may
               immediately, or at any time thereafter, without notice, perform
               the same for the account of the Tenant. If a notice of mechanic's
               lien be filed against the demised premises or against premises of
LANDLORD       which the demised premises are part, for, or purporting to be
MAY            for, labor or material alleged to have been furnished, or to be
PERFORM        furnished to or for the Tenant at the demised premises, and if
               the Tenant shall fail to take such action as shall cause such
               lien to be discharged within fifteen days after the filing of
               such notice, the Landlord may pay the amount of such lien or
               discharge the same by deposit or by bonding proceedings, and in
               the event of such deposit or bonding proceedings, the Landlord
               may require the lienor to prosecute an appropriate action to
ADDITIONAL     enforce the lienor's claim. In such case, the Landlord may pay
RENT           any judgment recovered on such claim. Any amount paid or expense
               incurred by the Landlord as in this subdivision of this lease
               provided, and any amount as to which the Tenant shall at any time
               be in default for or in respect to the use of water, electric
               current or sprinkler supervisory service, and any expense
               incurred or sum of money paid by the Landlord by reason of the
               failure of the Tenant to comply with any provision hereof, or in
               defending any such action, shall be deemed to be "additional
               rent" for the demised premises, and shall be due and payable by
               the Tenant to the Landlord on the first day of the next following
               month, or, at the option of the Landlord, on the first day of any
               succeeding month. The receipt by the Landlord of any instalment
               of the regular stipulated rent hereunder or any of said
               "additional rent" shall not be a waiver of any other "additional
               rent" then due.

                        EIGHTH. -- The failure of the Landlord to insist, in any
               one or more instances upon a strict performance of any of the
               covenants of this lease, or to exercise any option herein
AS TO          contained, shall not be construed as a waiver or a relinquishment
WAIVERS        for the future of such covenant or option, but the same shall
               continue and remain in full force and effect. The receipt by the
               Landlord of rent, with knowledge of the breach of any covenant
               hereof, shall not be deemed a waiver of such breach and no
               waiver by the Landlord of any provision hereof shall be deemed to
               have been made unless expressed in writing and signed by the
               Landlord. Even though the Landlord shall consent to an assignment
               hereof no further assignment shall be made without express
               consent in writing by the Landlord.

                        NINTH. -- If this lease be assigned, or if the demised

OF RENT        other than the Tenant the Landlord may collect rent from the
FROM OTHERS    assignee, under-tenant or occupant, and apply the net amount
               collected to the rent herein reserved, and no such collection
               shall be deemed a waiver of the covenant herein against
               assignment and underletting, or the acceptance of the assignee,
               under-tenant or occupant as tenant, or a release of the Tenant
               from the further performance by the Tenant of the covenants
               herein contained on the part of the Tenant.

                        TENTH. -- This lease shall be subject and subordinate at
MORTGAGES      all times, to the lien of the mortgages now on the demised
               premises, and to all advances made or hereafter to be made upon
               the security thereof, and subject and subordinate to the lien of
               any mortgage or mortgages which at any time may be made a lien
               upon the premises. The Tenant will execute and deliver such
               further instrument or instruments subordinating this lease to the
               lien of any such mortgage or mortgages as shall be desired by any
               mortgagee or proposed mortgagee. The Tenant hereby appoints the
               Landlord the attorney-in-fact of the Tenant, irrevocable, to
               execute and deliver any such instrument or instruments for the
               Tenant.

                        ELEVENTH. -- All improvements made by the Tenant to or
IMPROVEMENTS   upon the demised premises, except said trade fixtures, shall when
               made, at once be deemed to be attached to the freehold, and
               become the property of the Landlord, and at the end or other
               expiration of the term, shall be surrendered to the Landlord in
               as good order and condition as they were when installed,
               reasonable wear and damages by the elements excepted.

                        TWELFTH. -- Any notice or demand when under the terms of
NOTICES        this lease or under any statute must or may be given or made by
               the parties hereto shall be in writing and shall be given or made
               by mailing the same by certified or registered mail addressed to
               the respective parties at the addresses set forth in this lease.

                        THIRTEENTH. -- The Landlord shall not be liable for any
LIABILITY      failure of water supply or electrical current, sprinkler damage,

               persons in said building, or resulting from steam, gas,
               electricity, water, rain or snow, which may leak or flow from any
               part of said buildings, or from the pipes, appliances or plumbing
               works of the same, or from the street or sub-surface, or from
               any other place, nor for interference with light or other
               incorporeal hereditaments by anybody other than the Landlord, or
               caused by operations by or for a governmental authority in
               construction of any public or quasi-public work, neither shall
               the Landlord be liable for any latent defect in the building.

               comply with any law, ordinance or order of a governmental
               authority. In respect to the various "services," if any, herein
               expressly or impliedly agreed to be furnished by the Landlord to
               the Tenant, it is agreed that there shall be no diminution or
               abatement of the rent, or any other compensation, for
               interruption or curtailment of such "service" when such
               interruption or curtailment shall be due to accident, alterations
               or repairs desirable or necessary to be made or to inability or
               difficulty in securing supplies or labor for the maintenance of
               such "service" or to some other cause, not gross negligence on
               the part of the Landlord. No such interruption or curtailment of
               any such "service" shall be deemed a constructive eviction. The
               Landlord shall not be required to furnish, and the Tenant shall
               not be entitled to receive, any of such "services" during any
               period wherein the Tenant shall be in default in respect to the
               payment of rent. Neither shall there be any abatement or
               diminution of rent because of making of repairs, improvements or

               may from time to time be needful for the safety, care or
               cleanliness of the building, and for the preservation of good
               order therein. The Tenant and the employees and agents of the
               Tenant will observe and conform to all such rules and
               regulations.

                and furnish the Landlord with policies of insurance covering
                the same.

                        TWENTY-THIRD.--If by reason of the conduct upon the
INCREASED       demised premises of a business not herein permitted, or if by
     FIRE       reason of the improper or careless conduct of any business upon
INSURANCE       or use of the demised premises, the fire insurance rate shall at

                that part of all fire insurance premiums hereafter paid out by
                the Landlord which shall have been charged because of the

                demised premises, and will make such reimbursement upon the
                first day of the month following such outlay by the Landlord;
                but this covenant shall not apply to a premium for any period
                beyond the expiration date of this lease, first above specified.
                In any action or proceeding wherein the Landlord and Tenant are
                parties, a schedule or "make up" of rate for the building on the
                demised premises, purporting to have been issued by New York
                Fire Insurance Exchange, or other body making fire insurance
                rates for the demised premises, shall be prima facie evidence of
                the facts therein stated and of the several items and charges
                included in the fire insurance rate then applicable to the
                demised premises.

                consumption of water, as and when bills therefor are rendered.
                If the demised premises, or any part thereof, be supplied with
                water through a meter which supplies other premises, the Tenant
                will pay to the Landlord, as and when bills are rendered

                water consumed through said meter, as indicated by said meter.
                Such proportionate part shall be fixed by apportioning the
                respective charge according to floor area against all of the
                rentable floor area in the building (exclusive of the basement)
                which shall have been occupied during the period of the
                respective charges, taking into account the period that each
                part of such area was occupied. Tenant agrees to pay as
                additional rent the Tenant's proportionate part, determined as
  SEWER         aforesaid, of the sewer rent or charge imposed or assessed upon

                be indicated by the meter furnished therefor. The price for said
                current shall be the same as that charged for consumption
                similar to that of the Tenant by the company supplying
                electricity in the same community. Payments shall be due as and
                when bills shall be rendered. The Tenant shall comply with like
                rules, regulations and contract provisions as those prescribed
                by said company for a consumption similar to that of the Tenant.

                        TWENTY-SIXTH.--If there now is or shall be installed in

                alterations, additional sprinkler heads or other equipment in
                the demised premises are necessary to prevent the imposition of
                a penalty or charge against the full allowance for a sprinkler
                system in the fire insurance rate as fixed by said Exchange, or
                by any Fire Insurance Company, the Tenant will at the Tenant's
                own expense, promptly make and supply such changes,
                modifications, alterations, additional sprinkler heads or other

Landlord and Tenant, Tenant's use or occupancy of the Lease premises, and/or any
claim of injury or damage. In the event Landlord commences any proceeding for
non-payment of rent, minimum rent or additional rent, Tenant will not interpose
any counterclaims of whatever nature or description in any such proceeding. This
shall not, however, be construed as a waiver of the Tenant's right to assert
such claims in any separate action or actions brought by the Tenant.

39th. LEGAL EXPENSES: In case suit shall be brought for recovery of possession
of the leased premises, for the recovery of rent or any other amount due under
the provisions of this Lease, or because of the breach of any other covenants

it harmless from and against any and all claims, actions, damages, liabilities
and expenses in connection with loss of life, personal injury and/or damage to
property arising from or out of any occurrence in, upon or at the leased
premises or any part thereof, or occasioned wholly or in part by any act or
omission of Tenant, its agents, contractors, employees, servants, lessees or
concessionaires. In case Landlord shall , without fault on its part be made a
party to any litigation commenced by or against Tenant, then Tenant shall
protect and hold Landlord harmless and shall pay all costs, expenses and
reasonable attorney's fees incurred or paid by Landlord in connection with such
litigation.
<PAGE>   5
41st. LIENS: Tenant agrees not to suffer or permit during the demised term, any
mechanic's or other lien for work, labor and services and/or materials furnished
or otherwise to attach to and become a lien upon the premises as a result of any
work done by or on behalf of Tenant. If such lien shall so attach, Tenant shall
within 30 days after notice thereof, either pay or satisfy the same or procure
the discharge thereof of record in such manner as may be permitted or provided
by law. Should Tenant fail or refuse to discharge any such lien within the
period herein provided, then Landlord is hereby authorized to add the amount of
the said lien to any regular installment of rent thereafter becoming due as
additional rent.

42nd. ESTOPPEL CERTIFICATE: Within ten (10) days after request therefor by
Landlord, Tenant shall deliver in recordable form a certificate to Landlord or

or stating those defaults or claims claimed by Tenant; such certificate to be
furnished without charge.

43rd. NOTICE: All notices, requests, demands or other communications desired or
required to be given under any of the provisions hereof shall be in writing and
shall be deemed to have been duly given on the date mailed if sent by certified
mail addressed to Tenant at 50 Marcus Blvd., Hauppauge, New York 11788, and to
the Landlord at 684 Broadway, Massapequa, New York 11758, or at such other or
additional address as the parties may furnish by such notice to the other.

44th. NO BROKER: Tenant represents and warrants to the Landlord that Tenant has
dealt with no real estate broker, real estate company or salesman as to give
rise to any claim for brokerage commission or similar compensation and the
Tenant does herewith hold harmless, save and indemnify the Landlord from any
claims of any real estate brokers, real estate companies or real estate
salesmen for brokerage commissions.

45th. UTILITIES: The Tenant agrees to pay for all utilities utilized by it in
connection with its occupancy for the demised premises including, but not by way
of limitation to, fuel, oil, electricity, gas (if any) and water. The Tenant
further agrees to have the aforementioned utilities placed in its name and to
make any requisite deposits therefor before occupying the demised premises. The
Tenant further agrees to pay for the aforesaid utilities within ten (10) days
after bills therefor have been received by it.

46th. CERTIFICATES AND PERMITS: During the entire term of this lease, the Tenant
shall be required to keep in full force and effect all necessary certificates
for the purposes for which the demised premises are rented, permits and other
approvals or consents required by any governmental authority having jurisdiction

this Lease.

47th. INSURANCE:

         (a) Tenant, at its cost, shall maintain a policy of standard fire and
extended coverage insurance with vandalism and malicious mischief endorsements
to the extent of at least 80% of full replacement value, defined as follows:
$2,500,000.00. The insurance policy shall be issued in the names of Landlord,
Tenant and Landlord's lender, if any, now or in the future, as their interests
appear. The insurance policy shall provide that any proceeds shall be made
payable to Landlord or Landlord's lender as Landlord may designate. If
necessary, and at Landlord's request, the Tenant agrees to assign and deliver at
the commencement of this Lease, said insurance policy to the Landlord and the
said policy and renewal thereof shall be held by said Landlord. In the event the
Tenant does not pay the premiums as they fall due on said policy, Landlord shall
have the option of paying said premiums on behalf of Tenant, and adding the cost
thereof to the next month's rent due Landlord under the terms of this Lease as
additional rent and to collect same as "additional rent".

         (b) Tenant, at its cost, shall maintain plate glass insurance and
public liability and property damage insurance and products liability insurance
<PAGE>   6
with liability limits of not less than $500,000.00 per person per occurrence and
$1,500,000.00 per occurrence and property damage limits of not less than
$50,000.00, insuring against all liability of Tenant and its authorized
representatives arising out of and in connection with Tenant's use, occupancy
and possession of the premises. All public liability insurance and products
liability insurance and property damage insurance shall insure performance by
Tenant of the indemnity provisions of paragraph "40th" of this Rider. Both
parties shall be named as co-insureds and the policy shall contain
cross-liability endorsements and the original policy shall be delivered to
Landlord at the commencement of this Lease. In the event the Tenant does not pay
the premiums as they fall due on said policies, Landlord shall have the option
of paying said premiums on behalf of Tenant, and adding the cost thereof to the
next month's rent due Landlord under the terms of this Lease as additional rent
and to collect said as "additional rent".


48th. DESTRUCTION:

         (a) If, during the term of this Lease, the premises are totally or
partially destroyed from a risk covered by the insurance described in paragraph
"47th" of this Rider, rendering the premises totally or partially inaccessible
or unusable, or partially damaged but still usable, Tenant shall restore the
premises to substantially the same condition as they were in immediately before
destruction, whether or not the insurance proceeds are sufficient to cover the
actual cost of restoration. Such destruction shall not terminate this Lease.
However, if premises are not able to be used by Tenant for its business
operation, rent will abate until premises are restored.

         (b) If, during the term of this lease, the premises are destroyed in a
manner described in subparagraph "(a)" of this paragraph "48th", both Tenant and
Landlord shall make the loss adjustment with the insurance company insuring the
loss, and on receipt of the proceeds, same shall be paid to Landlord and
Landlord shall hold same in escrow as follows:

All sums deposited with the Landlord shall be paid in installments by the
Landlord to the contractor retained by Tenant as construction progresses for
payment of the cost of restoration. A 10% retention fund shall be established
that will be paid to the contractor on completion of restoration, payment of all
costs, expiration of all applicable lien periods and proof that the premises are
free of all mechanic's liens and lienable claims, and the furnishing of all
municipal certificates. If the Landlord in its reasonable discretion determines
that a particular installment requested by Tenant or Tenant's contractor is
improper, it shall have the right to appoint its own construction supervisor to
determine the validity of such installment and to make payments on certificates
approved by Landlord's construction supervisor, and the reasonable expenses of
Landlord's construction supervisor shall be paid out of the escrow funds and
charged to Tenant's account.

         Both parties agree to promptly execute all documents and perform all
acts reasonable required by either Landlord or any substitute insurance trustee
to perform its obligations under this paragraph.

49th. CONSENT OF PARTIES: Whenever consent or approval of either party is
required, that party shall not unreasonably withhold such consent or approval
except as same may be limited by paragraph "37th" of this Rider.

50th. ADDITIONAL RENT: The Tenant shall pay as additional rent any money
required to be paid pursuant to this Lease and all other sums of money or
charges required to be paid by Tenant under this Lease whether or not the same
be designated as "additional rent". If such amounts or charges are not paid at
the time provided in this Lease or if real estate taxes, increases, water
charges or assessments as well as insurance premiums are not paid within the
grace period allowed by the taxing authorities, water companies or insurance
companies, they shall, nevertheless, if not paid when due, be collectible as
additional rent with any installment of rent thereafter falling due hereunder,
but nothing herein contained shall be deemed to suspend or delay the payment of
any money, charge or amount at the time same becomes due and payable hereunder,
or limit any other remedy of the Landlord.

51st. AS IS: The Tenant does herewith acknowledge and declare that it is fully
familiar with the premises and environs and the buildings and improvements
<PAGE>   7
thereon, and accepts said premises and environs, the buildings and improvements
thereon in an "as is" condition, and Landlord makes no representation or
warranty as to the fitness, feasibility or use of the demised premises, and any
violations placed on the premises either prior to or after the date hereof,
shall be removed by Tenant; PROVIDED, HOWEVER, that at the commencement of the
within Lease, it shall be the Landlord's responsibility to place the electric
oil burner and air-conditioning systems in working order.

52nd. CONFLICT IN LANGUAGE: Should any conflict in language or interpretation
occur between the printed provisions of this Lease and the provisions contained
in the Rider of the Lease, the parties agree that the provisions contained in
the Rider of the Lease, the parties agree that the provisions in the Rider shall
prevail. All reference to paragraph numbers in the Rider shall refer to
paragraphs so numbered in the Rider and not to paragraphs in the printed portion
of this Lease unless so designated or unless the context of the Rider is
intended to designate the printed portion of the Lease.

53rd. AGREEMENTS BETWEEN PARTIES: This Lease contains all of the agreements and
understandings of the parties and cannot be amended or modified except by a
written agreement.

54th. SEVERABILITY: The unenforceability, invalidity or illegality of any
provision of this Lease shall not render the other provisions unenforceable,
invalid or illegal.

55th. SUCCESSORS: This Lease shall be binding on and inure to the benefit of the
parties and their successors, heirs and assigns.

56th. TAXES:

         (a) The Tenant shall, and will, during the term herein demised, pay and
discharge all such duties, taxes, charges for water, sewer taxes, assessments
and payments, extraordinary as well as ordinary, whether foreseen or unforeseen,
as shall during the term hereby demised by laid, levied, assessed or imposed
upon, or become due and payable, or liens upon the said demised premises, or any
part thereof, or any appurtenances thereto, the leasehold estate hereby created,
the sidewalks or streets in front of or adjoining the demised premises or any
vault or vaults thereunder, by virtue of any present or future law, order or
ordinance of the United States of America, or of the city, county or local
government, or of any department, office or bureau thereof, or any other
governmental authority. The duties, taxes, charges, assessments and payments
described in the foregoing paragraph are sometimes referred to herein
collectively as "Impositions ".

         (b) All impositions mentioned in this paragraph shall be paid by the
Tenant when the same shall become due and payable without interest or penalty to
the department, office or bureau charged with the collection thereof. But
nothing herein contained shall require the Tenant to pay any inheritance,
franchise, income, payroll, excise, privilege, rent, capital stock, estate or
profit tax, or any tax of similar nature, that is or may be imposed upon the
Landlord, unless such taxes shall be levied upon the rent herein reserved in the
place of taxes upon the property herein demised. All taxes, assessments and
water rents that are mentioned above to be paid by Tenant shall be prorated and
adjusted for the fiscal years in which the terms begins and ends.

         (c) In the case of assessments for local improvements or betterments
which are assessed or imposed during the term hereof and which may be payable in
installments, Tenant shall only be obligated to pay such installments as fall
due during the term hereof.

         (d) In any suit or proceedings of any kind or nature arising or growing
out of the failure of the Tenant to keep any covenant contained in this
paragraph, the certificate or receipt of the department, office or bureau
charged with collection of the imposition, showing that the tax, water rent,
assessment or other charge, affecting the demised premises is due and payable,
or has been paid, shall be prima facie evidence that such tax, water rent,
assessment or other charge was due and payable as a lien or charge against the
demised premises or that




                                      -4-
<PAGE>   8
it has been paid as such by the Landlord.

         (e) The Tenant shall have the right to contest or review by legal
proceedings or in such manner as Tenant, in its opinion shall be deemed
advisable (which proceedings or other steps taken by Tenant, if instituted,
shall be conducted diligently at its own expense and free of expense to the
Landlord) any and all impositions levied, assessed or imposed upon or against
the demised premises or the building or improvements thereon, or taxes in lieu
thereof, required to be paid by Tenant hereunder. No such context or review
shall be undertaken in a manner that exposes the premises or Landlord's interest
therein to jeopardy.

         (f) Tenant upon request of Landlord will promptly exhibit to Landlord
all paid bills for real estate taxes, water rates and assessments, which bills
after inspection by the Landlord shall be returned to the Tenant.

         (g) Notwithstanding the foregoing provisions of this paragraph, Tenant
agrees at the election of Landlord, to pay to Landlord the amount of the
impositions imposed upon the demised premises for each fiscal tax year, in equal
monthly installments on the first day of each month during such fiscal tax year.
Such payments shall in the first instance be based on the impositions for the
prior fiscal tax year, and when the impositions shall be ascertained for the
current tax year, appropriate adjudgments shall be made. No interest shall be
paid by Landlord or Tenant on the monthly payments by Tenant, but the same will
be kept by Landlord in a separate escrow account, the funds whereof shall be
employed by Landlord to pay the impositions for the current tax year as they
mature. It is further agreed that if an imposition is payable in full before the
expiration of the fiscal tax year, whether in installments or by lump sum
payment, the monthly payments by Tenant shall be in amounts such that there
shall be a fund in Landlord's hands sufficient to meet the payment of any
imposition or installment thereof as it falls due. Each monthly payment of
Tenant shall be in an equal amount during the period between impositions payment
dates; in any event, at least ten days in advance of the last date for payment
of any imposition, or installment thereof, before a penalty or interest accrues
thereon, Tenant will deposit with Landlord an amount sufficient to make up any
deficiency for that payment.


57th. TERM OF LEASE:

         Unless sooner terminated, this Lease shall terminate on the tenth
anniversary of the last day of the month preceding the month during which the
original term of this Lease commences. Upon request of either the Landlord or
Tenant, the other party shall execute a document in recordable form, setting
forth the exact commencement date of the term hereof.

58th. MORTGAGE: Reference is herein made to a certain mortgage now a lien on the
demised premises presently held by the Union Savings Bank, and to the proposed
mortgage contemplated to become a lien on the demised premises to be held by the
New York State Job Development Authority. In the event that the interest rates
as to either or both of said mortgages should increase during the term of the
within Lease, the Tenant shall pay to the Landlord, as additional rent
hereunder, such sums as shall equal the amount of such increase or increases ,
as same should occur throughout the term of this Lease. Said additional rent
shall be paid on a monthly basis commencing on the first of the month following
each written notification to the Tenant of an interest increase hereunder.

59th. SUBORDINATION: This Lease shall be subject and subordinate to any and all
mortgages which may now or hereafter affect the Landlord's interest in the real
property of which the demised premises form a part, and of all renewals,
modifications, consolidations, replacements and extensions thereof. This clause
shall be self-operative and no further instruments of subordination shall be
required. In confirmation of such subordination Tenant shall execute promptly
any certificate that Landlord may request. Tenant hereby constitutes and
appoints Landlord/Tenant's attorney-in-fact to execute any such certificate or
certificates for and on behalf of the Tenant.




                                      -5-
<PAGE>   9
60th. IMPROVEMENTS: it is understood and agreed that all improvements of
whatsoever nature, any and all additions to the building, together with any and
all fixtures attached to the demised premises shall immediately become the
property of the Landlord, and shall be surrendered at the end of the demised
term, in good condition, reasonable wear and tear excepted.

or permit anything to be done in or upon the demised premises which shall
increase the rate of fire insurance applicable to the completed building at the
time that the Tenant enters into possession thereof and based upon Tenant's
occupancy thereof for the uses hereinabove provided. If by reason of the failure

insurance premiums thereafter paid by the Landlord which shall have been charged
because of such failure or use by the Tenant, and shall make such reimbursement

improvements in or to the demised premises without the Landlord's express
written consent except as otherwise set forth herein. All alterations,

property of the Landlord, and shall remain upon, and be surrendered with, said
premises, as a part thereof, at the end of the term or renewal term, as the case
may be. In the event the Landlord shall elect otherwise, then such alternations,
decorations, installations, additions or improvements made by the Tenant upon
the demised premises as the Landlord shall select shall be removed by the Tenant
and the Tenant shall restore premises to the original conditions, at its own
cost and expense,

subsequent rent payment.

premises, including, without limitation, any claims made by any succeeding
Tenant founded on such delay. In the case of any holdover, the monthly rent

building for the uses permitted under the applicable zoning ordinances.

                     States or in connection with any rule, order or regulation
                     of any department or subdivision thereof of any government
                     agency or by reason of the conditions of supply and
                     demand which have been or are affected by war or other
                     emergency.

                     THE LANDLORD COVENANTS  

QUIET                     FIRST.--That if and so long as the Tenant pays the 
POSSESSION           rent and "additional rent" reserved hereby, and performs 
                     and observes the covenants and provisions hereof, the 
                     Tenant shall quietly enjoy the demised premises, subject,
                     however, to the terms of this lease, and to the mortgages
                     above mentioned, provided however, that this covenant
                     shall be conditioned upon the retention of title to the
                     premises by Landlord.
        

                          AND IT IS MUTUALLY UNDERSTOOD AND AGREED that the
                     covenants and agreements contained in the within lease
                     shall be binding upon the parties hereto and upon their
                     respective successors, heirs, executors and
                     administrators.
        
                          IN WITNESS WHEREOF, the Landlord and Tenant have
                     respectively signed and sealed these presents the day and
                     year first above written.

<PAGE>   5
         RIDER TO LEASE dated July 31, 1995 between 160 OSER AVENUE ASSOCIATES,
as Landlord, and MANCHESTER EQUIPMENT CO., INC., as Tenant.

         1. Anything herein, to the contrary notwithstanding, Tenants shall, at
Tenants' own cost and expense, secure and pay for all interior repairs,
replacements, utilities, maintenance and services required by Tenants or for
preservation of the demised premises, including, but not limited to: gas,
electricity, telephone, light, janitorial services, plumbing, wiring, carpentry,
mechanical, plate glass, electrical, air-conditioning, store front, painting,
decorating and maintenance services, heat, fuel, garbage and waste disposal,
snow removal, water, hot water and sewer rent. Any fees or deposits for permits
or licenses for machinery, meters, signs or any other equipment or usage, shall
be made, secured, and/or paid for by Tenants at Tenants' own cost and expense.
Except as expressly provided in this Lease, Landlord shall have no obligation to
furnish or perform interior repairs, maintenance or services; provided however,
that Landlord shall be responsible for so-called "structural" repairs, defined
as exterior walls, structural members and foundation. As designated in the
within paragraph, "utilities" refers solely to those utilities consumed by the
within Tenant; i.e. the within Tenant shall have no responsibility for the
utilities consumed by other Tenants in the building in which the demised
premises are located.

         2. Anything herein to the contrary notwithstanding, Tenants are hereby
given permission to erect any sign or signs in and about the demised premises at
Tenant's own cost and expense, provided: (a) Any such sign shall comply with all
rules and regulations of any governmental authority having jurisdiction thereof;
(b) Said sign or signs shall be installed without damage to Landlord's building
including signs on each exterior wall; (c) Upon the removal of any such signs,
all damage occasioned thereby shall be repaired by Tenants at Tenants' own cost
and expense.

         3. Tenants shall secure, pay for and maintain during the term of this
Lease, a policy of general liability insurance, (having limits:
$1,000,000/2,000,000 for bodily injury; $100,000 for properly damage) from a
financially responsible insurer licensed to do business in the State of New
York; which said policy shall name as protected, the Tenants and Landlord as the
fee owner, as their respective interests shall appear, and any other parties
designated by Tenants, and shall contain a waiver of subrogation as against the
Landlord as fee owner. Tenants shall deliver to the Landlord a certificate of
such insurance policy on or before the beginning of the term of this Lease. In
any such policy, the bodily injury coverage shall be written on an "Occurrence"
basis and shall include personal injury coverage; and shall also provide that no
modification, termination or cancellation thereof shall be effective until after
ten (10) days prior written notice has been given to Landlord by the insurance
carrier, to be forwarded by Certified or Registered Mail, Return Receipt
Requested. In the event of the failure of the Tenant

                                      {1}
<PAGE>   6
to secure, maintain and pay for such policy and to provide a certificate thereof
to Landlord, Landlord may, in Landlord's sole discretion, order such policy and
the premium cost thereof shall be due from Tenant as additional rent hereunder
or Landlord may elect to treat such failure as a default hereunder, in which
case, Tenant agrees such default is a material default of the Lease.

         4. Tenant, at its cost, shall maintain a policy of standard fire and
extended coverage insurance with vandalism and malicious mischief endorsements
to the extent of at least eighty [80%] percent of full replacement value as to
the demised structure and its environs, defined as follows: $850,000.00. The
insurance policy shall be issued in the name of Landlord, Tenant and Landlord's
lender, if any, now or in the future, as their interests appear. The insurance
policy shall provide that any proceeds shall be made payable to the Landlord or
Landlord's lender, as Landlord may designate. The Tenant agrees to assign and
deliver at the commencement of this Lease said insurance policy to the Landlord
and the said policy and renewal thereof shall be held by said Landlord. In the
event the Tenants do not pay the premiums as they fall due on said policy,
Landlord shall have the option of paying said premiums on behalf of Tenants, and
adding the cost thereof to the next month's rent due Landlord under the terms of
this Lease as additional rent and to collect same as "additional rent".

         The foregoing insurance policy shall provide that no modification,
termination or cancellation thereof shall be effective until after thirty [30]
days prior written notice has been given to the Landlord by the insurance
carrier, certified mail, return receipt.

         If any extraordinary or excessive insurance premium cost is charged to
Landlord as the result of the nature of Tenant's business, or its use and
occupancy of the demised premises or an installation, condition or alteration
made or maintained by Tenant therein, the full cost of such excess premium or
extraordinary charge shall be borne by and paid by Tenant. The finding or
"make-up" of rate established by the New York Fire Rating Organization [or such
other agency having jurisdiction and responsibility for rating the building for
insurance purposes] shall be admissible as evidence in any action and proceeding
and shall be deemed conclusive evidence of the facts therein stated and of the
items and charges then applicable to the building and the demised premises
located therein. The total costs of insurance and the totality of coverage shall
not exceed that which is reasonable and customary.

         5. The Tenants agree to indemnify the Landlord, as fee owner, and the
respective officers, directors, agents, servants and employees thereof against
and to defend, save and hold them harmless of and from, any and all liability,
cost and damage for or arising by reason of any and all claims, suits or causes
of action for bodily injury, personal injury, death or property damage to any
and all persons in any manner caused


                                      {2}
<PAGE>   7
by acts, negligence or omissions of, or any condition created, caused, permitted
or suffered by, the Tenants, its officers, directors, agents, servants, and
employees.

         6. Except for injury, loss or damage occasioned directly and
specifically as the result of the Landlord's negligence, the Landlord shall not
be liable or responsible to the Tenants for the safekeeping of any goods or
other property of the Tenant, nor for injury to any person or persons or any
damage to or loss of merchandise or other property of the Tenants occasioned by
theft, fire, water, power failure, accident or the bursting, leaking or running
in the demised premises of any plumbing, heating, electrical apparatus, gas,
steam or pipes of any nature, or from any other cause whatsoever; and except for
injury, loss or damage due to Landlord's negligence, anything herein to the
contrary notwithstanding, the Tenant, for itself and its insurers, releases
Landlord of and from any and all such liability and responsibility.

         7. It is understood and agreed that under any and all circumstances,
the liability of the Landlord shall not be personal and whenever Tenants, their
agents, servants or employees seek or recover any money judgment or other award
of damages against the Landlord from any Court, administrative body or tribunal
of competent jurisdiction, that satisfaction thereof shall be solely and
expressly limited to levy of execution against and collection out of the
interest of the Landlord in and to the demised premises and/or the land and
building of which the demised premises forms a part, and the Tenants for
themselves, their agents, servant and employees, heirs, successors and assigns,
expressly and specifically relinquishes, waives and releases any and all rights
to seek, secure, recover or collect any portion of such judgment, damages or
award against or from the Landlord personally or from any other property, assets
or estate of the Landlord, its heirs, successors, officers, directors,
shareholders, legal representatives, agents, servant, employees or assigns.

         8. In lieu of the Landlord not requiring the Tenant to maintain a
policy of plate glass insurance, it is specifically agreed that the Tenant shall
be solely responsible for the replacement of any and all plate glass damage at
the Tenant's cost and expense. In the event the Tenant fails to replace and or
repair plate glass within a reasonable time after damage thereto, the Landlord
shall have the right to repair said plate glass damage, and in such event, the
landlord is hereby authorized to add the cost of such repair to any regular
installment of rent thereafter becoming due, as additional rent.

         9. Tenants shall bear and pay to the Landlord as additional rent during
each Lease year, the cost to Landlord of the following:

            A. Commencing with the rental due August 1, 1995, the fixed annual
rent hereinbefore set forth for each fiscal year of this Lease (hereinafter a
"lease year") shall be increased by additional rental in an amount equal to one
hundred [100%] percent of the amount expended for taxes, [as hereinafter
defined], in such Lease year.

                                      {3}
<PAGE>   8
         Such additional rental shall be paid by the Tenants within fifteen (15)
days after the Landlord shall have served upon Tenants a written statement
thereof. The Tenants or their authorized representative shall have the right to
inspect the books of the Landlord during its regular business hours for the
purpose of verifying the information set forth in the statement submitted by the
Landlord pursuant to this paragraph provided that written request for such
inspection shall be made by the Tenants within ten (10) days after the receipt
of such statement. For purposes of this paragraph, the term "Taxes" means real
estate taxes, transfer taxes, vault charges and other governmental taxes or
charges, special, ordinary or extraordinary, foreseen or unforeseen (but not
income, franchise, inheritance or capital stock taxes) which may now or
hereafter be levied or assessed against the lands and buildings of which the
demised premises form a part thereof. In the event the tax year does not
correspond with a Lease year, equitable proration shall be made in determining
the amount expended in respect of such period.

               (a) Every "lease year" during the term hereof shall be for a
period of twelve (12) full calendar months, except that the last Lease year
shall terminate on the date this Lease expires or is otherwise terminated.

               (b) In the event that as the result of changes in the laws,
enabling statutes or other code, rules or regulations, including but not limited
to the Internal Revenue Code, taxes or other levies or assessments against gross
rental income shall be substituted in whole or in part for any real property
taxes or assessments presently applicable to real property, then and to the
extent that such taxes shall be and constitute a substitute for the real
property taxes against the premises of which the demised premises forms a part,
such substitute tax or assessment shall be included in and considered part of
the real property taxes for the purposes of calculating the portion thereof to
be paid by Tenants as additional rent hereunder.
<PAGE>   9
         10. A. The amount of all such additional rent shall be due and payable
with the next regular monthly installment of rent following the submission to
Tenants of a bill, together with the calculation of additional rent due,
therefor by Landlord.

             B. A copy of the official tax bill, insurance premium bill or other
statement or invoice for a charge or expense to Landlord shall be deemed
sufficient and conclusive evidence of the amount of such charge or expense, a
percentage of which is payable by Tenant to Landlord as additional rent.

             C. If any extraordinary or excessive insurance premium cost is
charged to Landlord as the result of the nature of Tenant's business, or its use
and occupancy of the demised premises or an installation, condition or
alteration made or maintained

                                      {4}
<PAGE>   10
by Tenant therein, the full cost of such excess premium or extraordinary charge
shall be borne by and paid by Tenants. The finding or "make-up" of rate
established by the New York Fire Rating Organization (or such other agency
having jurisdiction and responsibility for rating the building for insurance
purposes) shall be admissible as evidence in any action and proceeding and shall
be deemed conclusive evidence of the facts therein stated and of the items and
charges then applicable to the building and the demised premises located
therein. The total costs of insurance and the totality of coverage shall not
exceed that which is reasonable and customary.

             D. The portion of the Landlord's costs or charges payable as
additional rent by Tenants shall be apportioned on the basis that the first
Lease year, the last Lease year or any Lease year does not coincide with the
fiscal year to which any such charge is applicable.


         11. It is specifically agreed that in the event of the default by
Tenants in the performance of this Lease or the payment when due of any
installment of rent or additional rent or any other sum due under this Lease,
the Landlord is expressly authorized, empowered, directed and entitled to use,
apply or retain as Landlord's sole property that portion or all of the security
deposited by Tenants on the signing of this Lease to the extent necessary to
cure such default or to reimburse Landlord for any sum which he may expend or be
required to expend by reason of Tenant's default. All or any portion of the said
security deposit thus used or applied by Landlord shall be made up and
redeposited by Tenants forthwith on demand to the original amount of the
security deposit required under this Lease. The security deposit to be made
hereunder and any additions thereto, shall be deposited by the Landlord in a
separate interest bearing savings account, and all interest accruing thereon
shall be deemed as additional security, and held by the Landlord pursuant to the
security provisions of the within Lease.

         12. Tenants agree that if Landlord shall pay or be compelled to pay a
sum of money or to perform any act that requires the payment of money, by reason
of the failure of the Tenant to keep, observe, or perform any of the terms,
covenants and provisions herein contained to be kept, observed or performed by
the Tenants, other than the payment of rent, then and in such event, the sum or
sums so paid by the Landlord shall, upon Landlord's demand, be paid by Tenants
to Landlord as additional rent, with interest thereon at the maximum rate of
interest allowable on the date of such demand, together with the installment of
the monthly base rent next due from date of said demand.

         13. Any and all notices, consents and other communications which either
party may desire or be required to give to the other shall be in writing and,
except as otherwise herein specifically provided, shall be sent by Certified
Mail, Return Receipt Requested, addressed to the party for whom intended at the
address first herein above

                                      {5}
<PAGE>   11
set forth or at such other address as such party may designate for such purpose
by notice duly given to the other. All such notices shall be deemed to have been
duly given on the third business day following the date of the deposit thereof,
securely enclosed in a postpaid wrapper addressed as above, in an official
depository maintained for mailing purposes by the U. S. Post Office Department
(or its successor postal agency).

         14. If any term, condition or provision of the printed portion of this
Lease shall be inconsistent with a provision of this Rider, then the
inconsistent portions of the printed Lease form shall be deemed superseded by
the provisions set forth in this Rider. Wherever appropriate for good usage or
meaningful interpretation, terms expressed in the neuter, masculine or feminine
gender shall be deemed interchangeable, as shall terms expressed in the singular
or plural be deemed interchangeable.

         15. In the event that any payment provided to be made hereunder shall
become overdue in excess of ten (10) days as additional rent, Tenant shall pay
to the Landlord a late charge of five (.05) cents for each dollar so overdue to
compensate Landlord for expenses incurred in handling such delinquent payment or
payments. The charges hereunder shall be due and owing regardless of application
of security pursuant to paragraph "10".

         16. On the written request of either party, the Landlord and the
Tenants each covenant and agree to execute, seal, acknowledge and deliver unto
the other, within ten (10) days of written request, a certificate attesting: (a)
Whether this Lease is current and in full and continuing force and effect; (b)
Whether there are any defaults, arrears, set-offs, claims, counter-claims or
defenses to or against the full enforcement of any of the terms, covenants and
conditions to be paid and performed hereunder; (c) To the amount of the rent
then being paid and the dates of the commencement and expiration of the term
hereof; (d) To the period for which and the amount of the rent which has then
been prepaid; and (e) Whether the other party has fully performed all
obligations on its part to be performed.

         17. It is specifically understood and agreed that any item required to
be paid by Tenants, including additional rent or payments for defaults, shall be
deemed rent, and upon the failure of Tenants to pay the same when due, it shall
be deemed equivalent to a default in the payment of rent and shall entitle
Landlord to invoke any and all remedies as in the case of non-payment of rent.

         18. In any case where Landlord brings any action or summary proceeding
for any default of the Tenants hereunder, whether for the non-payment of rent or
additional rent or any other default, Landlord shall be entitled to reasonable
attorney's fees if successful; plus filing fees, sheriff's fees, if any, for any
one action or proceeding. Parties each waive trial by jury in any summary
proceeding.

                                      {6}
<PAGE>   12
         19. The Tenants shall have the right to contest any real estate tax,
special assessments or other governmental charges levied against the real
property of which the demised premises are a part, by writ of certiorari, or
otherwise, in the same manner as provided by law for the owner of the property
to contest the same upon condition that the Tenants shall pay, immediately upon
billing, such real estate taxes, special assessments or other government charges
(looking to the taxing authorities for a refund thereafter), and upon the
further condition that the cost of such proceeding shall be borne solely by the
Tenants and the Tenants shall hold the Landlord free and harmless from any cost,
penalties, interest, damages or other liability otherwise incurred as the result
thereof. Landlord shall, at Tenant's request, execute such documents as are
reasonably necessary to carry out the foregoing. In the event the Tenant should
be successful in contesting as aforesaid, the result of which creates a refund
to the landlord, the following shall apply:

             Upon receipt by the Landlord of such refund, the Landlord shall
return to the Tenant the costs and expenses incurred by the Tenant in obtaining
such refund. The Tenants shall have a similar right to contest insurance costs
and any other costs charged pursuant to paragraphs "8" and "9".

         20. Ceiling lighting fixtures shall not be deemed trade fixtures, and
upon installation, the same shall become, be and remain Landlord's sole
property. All light bulbs, tubes, ballasts, starters, switches, lenses and
grills for such ceiling fixtures, and the servicing and maintenance thereof
shall at all times be solely the obligation of Tenant.

         21. A. Tenant covenants and agrees that it will occupy the entire
demised premises, and will conduct its business in the regular and usual manner,
throughout the term of this Lease. Tenants acknowledge that Landlord is
executing this Lease in reliance upon these covenants, and that these covenants
are a material element of consideration inducing the Landlord to execute this
Lease. Tenant further agrees that if it vacates the demised premises or fails to
so conduct its business therein, at any time during the term of this Lease,
without the prior written consent of the Landlord, then all rent and additional
rent reserved in this Lease from the date of such breach to the expiration date
of this Lease, shall become immediately due and payable to Landlord.

             B. The parties recognize and agree that the damage to Landlord
resulting from any breach of the covenants in subdivision (a) hereof will be
substantial and will be greater than the rent payable for the balance of the
term of this Lease, and will be impossible of ascertainment. The parties,
therefore, agree as follows:

                1. In the event of a breach or threatened breach of the said
covenants, in addition to all of Landlord's other rights and remedies, at law or
in equity

                                      {7}

or otherwise, Landlord shall have the right of injunction to preserve Tenant's
occupancy and use. The words "become vacant or deserted" as used elsewhere in
this Lease shall include Tenant's failure to occupy or use as by this Article
required.

                2. If Tenants breach either of the covenants in subdivision (a)
above, and this Lease be terminated because of such default, then, anything in
this Lease as to the contrary notwithstanding;

                   (a) Landlord shall have the right to re-enter the demised
premises, and to alter, reconstruct and rent all or any part of the premises, at
any rental to which Landlord shall agree, for any portion of or beyond the
original term of this Lease.

                   (b) Any income received by Landlord on any such re-rental
shall be the property of the Landlord alone, as compensation for the expenses in
connection with the preparation and re-renting of the demised space, and,
together with the rents and additional rents payable as aforesaid, as liquidated
damages for the breach of Tenants, which damages cannot be computed, as
aforesaid. Tenants shall have no right to any portion of such income.

         22. In any action or summary proceeding brought by Landlord against
Tenants under this Lease (or any renewal, extension, holdover or modification
thereof), for non-payment of rent or additional rent, the Tenant hereby waives
the right to interpose, and expressly covenants and agrees not to interpose, any
counterclaim or set-off of whatever nature or description. The foregoing,
however, shall not be deemed or constitute a waiver of the Tenant's right to
commence and prosecute a separate action against Landlord on a bonafide claim.

         23. Every "Lease Year" during the term hereof shall be for a period of
twelve (12) full calendar months, except that the last Lease year shall
terminate on the date this Lease expires or is otherwise terminated.

         24. The fixed annual rent hereinafter provided is intended to be and
shall be absolutely net to Landlord. It is the intention of the parties hereto
that all expenses, costs and obligations of the parties hereto, all expenses,
costs and obligations of every kind and nature whatsoever relating to the
demised premises, (with the exception of the base real estate taxes and
structural repairs as defined herein), shall be paid by Tenants either directly
or as additional rent so that this Lease shall yield to Landlord the net fixed
annual rent specified during the term of this Lease.

         25. If any term or provision of this Lease or the application thereof
to any person or circumstances shall, to any extent, be invalid or
unenforceable, the remainder of this Lease, or the application of such term or
provision to persons or circumstances

                                      {8}
<PAGE>   14
other than those as to which it is held invalid or unenforceable, shall not be
affected thereby, and each term and provision of this Lease shall be valid and
be enforced to the fullest extent permitted by law.

         26. Tenants agree not to allow or permit during the demised term, any
mechanic's or other lien for work, labor and services and/or materials furnished
or otherwise to attach to and become a lien upon the premises as a result of any
work done by or on behalf of Tenants. If such lien shall so attach, Tenants
shall within thirty (30) days after notice thereof, either pay or satisfy the
same or procure the discharge thereof of record in such manner as may be
permitted or provided by law. Should Tenants fail or refuse to discharge any
such lien within the period herein provided, then Landlord is hereby authorized
to add the amount of the said lien to any regular installment of rent thereafter
becoming due as additional rent.

         27. During the entire term of this Lease, the Tenants shall be required
to keep in full force and effect all necessary Certificates of Occupancy for the
purposes for which the demised premises are rented, permits and other approvals
or consents required by any governmental authority having jurisdiction over the
business conducted by the Tenants as set forth in the purpose clause of this
Lease. The Landlord represents that the present zoning of the demised premises
is "C8".

         26. Should any conflict in language or interpretation occur between the
printed provisions of this Lease, the parties agree that the provisions in the
Rider shall prevail. All reference to paragraphs as set forth in the Rider shall
refer to paragraphs so indicated in the Rider and not to paragraphs in the
printed portion of this Lease, unless so designated or unless the context of the
Rider is intended to designate the printed portion of this Lease.

         29. This Lease contains all of the agreements and understandings of the
parties and cannot be amended or modified except by a written agreement.

         30. The unenforceability, invalidity or illegality of any provision of
the Lease shall not render the other provisions unenforceable, invalid or
illegal.

         31. This Lease shall not be recorded. No Memorandum shall be recorded
without the express written consent of the Landlord.

         32. Tenants covenant that the demised premises will not be used so as
to interfere with other Tenants in the same building.

         33. In the event the Tenants do not vacate the premises upon the
expiration date of this Lease, then and in that event, the Tenants shall remain
as month to month Tenants at a monthly rental 100% greater than the last monthly
rental paid during the

                                      {9}
<PAGE>   15
term of the Lease. Nothing herein shall grant the Tenants a right to holdover
after the expiration of the Lease term.

  34. The annual base rent for the years of the term of the within Lease shall
be as follows:

                                     Annual

         35. Notwithstanding any provision of the within Lease to the contrary,
written consent of the Landlord to an assignment of the within Lease, and/or
sub-Lease of a portion of the demised premises, shall be required. The Landlord
shall not unreasonably withhold its consent to such assignment or sub-Lease
provided the then Tenant has complied with the following terms and conditions:

             (a) The within Tenants shall not be in default as to any of the
terms and conditions of the within Lease, and the Lease shall be in full force

principal of said corporation, the date of the proposed assignment or sub-Lease,
and the proposed use of the premises by the assignee.

             (c) The use of the demised premises by the proposed assignee or
sub-lessee shall be substantially similar to the Tenant's use and purpose

                                      {10}
<PAGE>   16
             (e) Such assignment or sub-Lease shall in no manner discharge the
Tenant or any subsequent Tenants herein from any liability or obligation
whatsoever created by the within Lease, and such liability and obligation shall
continue for the remainder of the within Lease.

             (f) If Tenants are a corporation, any dissolution, merger,
consolidation or reorganization of Tenant or the sale or other transfer of fifty
(50%) percent or more of the capital stock of the Tenant shall be deemed an
assignment under the terms of this paragraph subject to all of the terms and
conditions specified herein; provided, however, that transfers of capital stock
of the Tenant between presently existing shareholders of the Tenant, or
transfers of capital stock to members of the immediate family of the present
shareholders of the Tenant, shall not be deemed an assignment pursuant to the
terms of the within paragraph.

             (g) If the Tenants are a corporation, or this Lease is subsequently
assigned to a corporation, the Tenant shall furnish the Landlord with a true
copy of a resolution duly adopted by the board of directors of such corporation
authorizing the corporation to enter into this Lease.

             (h) The Tenants shall be responsible for the payment of reasonable
attorney's fees to the Landlord's attorney for review of all documents and the
preparation of any additional documents, if necessary, which attorney's fees
will not exceed $750.00, plus any and all disbursements incurred.

             (i) That simultaneously with said assignment there shall be paid to
the Landlord, as additional security, a sum equal to two (2) months of the then
applicable rent, and same shall be held by the Landlord pursuant to the same
terms as the security recited herein in Lease paragraph "27". This provision
shall apply to each and every assignment or sub-Lease of the within Lease.

         36. Defaults and remedies. A. If (1) Tenants default in the payment of
any rent or any additional rent and such default continues for five (5) days
after written notice from Landlord or its agent or (2) Tenant defaults in
fulfilling any of the covenant or agreements or any rules or regulations of this
Lease on its part to be kept or performed and such default is not made good
within ten (10) days after written notice from Landlord or its agent, or within
such additional time as Tenant may be prevented from making good the default as
is caused by delays attributable to strikes, labor troubles, acts of God,
governmental prohibitions and similar causes beyond Tenant's control, or (3) If
this Lease is transferred to or devolve upon any person or corporation other
than Tenant, except as may be specifically permitted by this Lease, or if this
Lease is mortgaged or assigned without the written consent of the Landlord, then
and in any of such events mentioned in this subparagraph "A" the term thereof,
shall thereupon ipso facto expire and come to an end as if such expiration was
so fixed by

                                      {11}
<PAGE>   17
the terms of this Lease on the fifth (5th) or tenth (10th) day of such default
as mentioned in (1) and (2) above and upon the occurrence mentioned in (3) above
and Landlord may re-enter upon the demised premises either with or without
process of law and remove all persons therefrom and Tenant shall quit and
surrender the same to Landlord and Tenants shall remain liable as hereinafter
provided. In the event Tenants shall fail, neglect or refuse to quit and
surrender the demised premises upon receipt of notice from Landlord declaring
the term hereof at an end, then Landlord may commence a summary proceeding to
remove Tenant from the premises as a holdover. If pursuant to (2) the default is
of such a nature that it cannot be cured within ten (10) days, if Tenant
commences to cure such default within ten (10) days and proceeds diligently to
remedy such default, the Landlord shall not have the right to terminate this
Lease.

         B. If Tenants shall abandon the demised premises or if the premises
become and remain vacant or deserted for a period of fifteen (15) days, or if
the term of this Lease shall expire as hereinabove provided, or if Tenant fails
to take possession of the demised premises within forty-five (45) days after
commencement of the term of this Lease, Landlord may re-enter the demised
premises and remove Tenant or its legal representatives or other occupant by
summary proceedings or otherwise and Tenant hereby waives the service of notice
of intention or to institute legal proceedings to that end.

         C. In case of any re-entry, expiration and/or dispossess by summary
proceedings or otherwise, the rent shall become due thereupon and be paid up to
the time of such re-entry, dispossess and/or expiration, together with such
expenses as Landlord may incur for legal expenses, attorneys fees, brokerage
and/or putting the demised premises in good order, or for preparing the same for
re-rental; Landlord may relet the premises or any part or parts thereof either
in the name of Landlord or otherwise, for a term or terms which may at the
Landlord's option be less than or exceed the period which may otherwise have
constituted the balance of the term of this Lease and may grant reasonable
concessions, or free rent; and Tenant or the legal representatives of Tenant
shall also pay Landlord as liquidated damages for the failure of Tenant to
observe and perform said Tenant's covenants herein contained, and deficiency
between all rent or additional rent hereby reserved and/or covenanted to be
paid, with percentage rental computed for the balance of the term for the
purpose of this article at the average annual percentage rent for the two (2)
full Lease years preceding the default or re-entry and the net amount, if any,
of the rents collected on account of the Lease of the demised premises, for each
month of the period which would otherwise have constituted the balance of the
terms of this Lease. In computing such liquidated damages there shall be added
to the said deficiency such expenses as Landlord may incur in connection with
reletting, such as reasonable legal expenses, attorneys fees, brokerage and for
keeping the demised premises in good order or for preparing the same for
reletting. Any such liquidated damages shall be paid in monthly installments by
Tenant on the rent days specified in this Lease. Any suit brought to collect the

                                      {12}
<PAGE>   18
amount of the deficiency for any month shall not prejudice in any way the rights
of Landlord to collect the deficiency for any subsequent month by a similar
proceeding. Landlord at Landlord's option may make such alterations, repairs,
replacements and/or decorations in the demised premises; and the making of such
alterations, repairs, replacement and/or decorations shall not operate or be
construed to release Tenant from liability hereunder as aforesaid. Landlord
shall not be liable for failure to relet the demised premises. The words
"re-enter" or "re-entry" as used in this Lease shall not be restricted to their
technical legal meaning. Any rents or other income received by Landlord on any
such re-rental shall be the property of Landlord alone and Tenant shall have no
right to any portion of such income. In the event that the Tenant is successful
in any proceeding brought pursuant to the provisions hereof, it shall be
entitled to its reasonable legal fees.

         D. In the event of a breach or threatened breach by Tenants of any of
the covenants or provisions of this Lease, Landlord shall have the right of
injunction and the right to invoke any remedy allowed at law or equity as if
re-entry, summary proceedings and other remedies were not herein provided for.
Mention in this Lease of any particular remedy shall not preclude Landlord from
any other remedy, in law or in equity. Tenants hereby expressly waive any and
all rights of redemption granted by order or any present or future laws in the
event of Tenants being evicted or dispossessed, or in the event of Landlord
obtaining possession of the demised premises by reason of Tenant's violation of
the provisions of this Lease. Tenants further waive the provisions of Section 
749, Subparagraph 3 of the Real Property Actions and Proceedings Law and any
successor statute thereto.

         E. In the event Tenants shall default in the payment of any rent or
additional rent as above provided, and such default shall continue for ten (10)
days after written notice from Landlord, or its agent and not be made good
within said ten (10) day period, then and in such event, Landlord may, at its
election, and in addition to any other remedy herein afforded, declare this term
at an end and accelerate the rent due for the entire Lease period. In such
event, the balance of the minimum rent reserved from the date of such default
until the last day of the Lease period, shall thereupon be forthwith due and
payable. Failure by Landlord to relet the premises shall not be deemed an offset
or defense to recovery of the aforesaid minimum rent due for the balance of the
term accelerated by reason of Tenant's default above mentioned. Landlord shall
be required to give the notice provisions contained in paragraph "12" hereof.

         F. If Tenants shall default in the performance of any provision,
covenant or condition on its part to be performed under this Lease, Landlord
may, at its option, perform the same for the account and at the expense of
Tenants. If Landlord at any time shall be compelled to pay or elected to pay any
sum of money by reason of the failure of the Tenant to comply with any provision
of this Lease, or if Landlord incurs any expense, including reasonable
attorney's fees in prosecuting or defending any action or

                                      {13}
<PAGE>   19
proceeding by reason of any default of Tenant under this Lease, the sums so paid
by Landlord with legal interest, costs, and damages shall be due from and be
paid by Tenant to Landlord on demand. All such sums, including all payments
required to be made by Tenants of any kind under this Lease, shall be deemed
additional rent and Landlord shall have all remedies for the collection thereof
that Landlord may have for non-payment of minimum rent. In the event that the
Tenants are successful in any proceedings brought pursuant to the provisions
hereof, it shall be entitled to its reasonable legal fees and costs.

         37. The Tenants represent, warrant and declare that they have been
afforded the opportunity to make exterior and interior inspection of the
premises which are the subject of this Lease, that they have either made such
inspection of the said premises, or has caused such inspection of the said
premises to be made, and the Tenants distinctly understand that the premises are
being leased in their present condition and state of repair, and tenants agree
that at the time of closing Tenants will accept the premises in their present
condition and state of repair.

         38. Prior to the commencement of any alterations contemplated by the
Tenants during the term of this Lease, the Tenants shall furnish written plans
and specifications therefor to the Landlord and obtain the Landlord's written
consent thereto, which consent will not be unreasonably withheld.

             (a) The Tenants will apply for and obtain any and all permits
therefor as same may be required by any municipal agency or authority having
jurisdiction, prior to the commencement of such alterations, and will apply for
and secure any and all requisite certificates of occupancy or certificates of
completion therefor.

             (b) The Landlord and Tenant acknowledge that the Tenant
contemplates causing extensive alterations and renovations to the demised
premises, at the Tenants' sole cost and expense.

             The Tenant shall notify the Landlord upon the completion of the
foregoing alterations and renovations. Upon inspection by the Landlord that same
have been performed in a workmanlike and satisfactory manner, and of all
requisite permits, completion certificates and/or Certificates of Occupancy, are
to be furnished to the Landlord.

         39. Tenant represents and warrants that Tenant did not consult with any
broker with regard to this transaction, and the Tenant agrees to indemnify and
save harmless the Landlord of any and all liability, expense, loss, cost or
damage that may arise by reason of any brokerage claims or demands by reason of
Tenant's acts, and makes this covenant as an express inducement to the Landlord,
intending that Landlord

                                      {14}
<PAGE>   20
shall rely thereon entering into this Lease. This covenant and representation is
irrevocable, and shall survive the execution of the within Lease.

         40. If any provision of this Rider shall be in conflict with any
provision of the printed form of this lease, the provisions of this Rider shall
control.

are non-structural and which do not affect utility services or  plumbing and
electrical lines, in or to the interior of the demised premises by using
contractors or mechanics first approved by Owner. Tenant shall, before making
any alterations, additions, installations or improvements, at its expense,
obtain all permits, approvals and certificates required by any governmental or
quasi-governmental bodies and (upon completion) certificates of final approval
thereof and shall deliver promptly duplicates of all such permits, approvals
and certificates to Owner and Tenant agrees to carry and will cause Tenant's
contractors and sub-contractors to carry such workman's compensation, general
liability, personal and property damage insurance as Owner may require. If any
mechanic's lien is filed against the demised premises, or the building of which
the same forms a part, for work claimed to have been done for, or materials
furnished to, Tenant, whether or not done pursuant to this article, the same
shall be discharged by Tenant within thirty days thereafter, at Tenant's
expense, by filing the bond required by law. All fixtures and all paneling,
partitions, railings and like installations, installed in the premises at any
time, either by Tenant or by Owner in Tenant's behalf, shall, upon installation,
become the property of Owner and shall remain upon and be surrendered with the
demised premises unless Owner, by notice to Tenant no later than twenty days
prior to the date fixed as the termination of this lease, elects to relinquish
Owner's right thereto and to have them removed by Tenant, in which event the
same shall be removed from the premises by Tenant prior to the expiration of the
lease, at Tenant's expense. Nothing in this Article shall be construed to give
Owner title to or to prevent Tenant's removal of trade fixtures, movable office
furniture and equipment, but upon removal of any such from the premises or upon
removal of other installations as may be required by Owner. Tenant shall
immediately and at its expense, repair and restore the premises to the condition
existing prior to installation and repair any damage to the demised premises or
the building due to such removal. All property permitted or required to be
remove, by Tenant at the end of the term remaining in the premises after
Tenant's removal shall be deemed abandoned and may, at the election of Owner,
either be retained as Owner's property or may be removed from the premises by
Owner, at Tenant's expense.

        MAINTENANCE AND REPAIRS.  4. Tenant shall, throughout the term of this
lease, take good care of the demised premises and the fixtures and
apportenances therein. Tenant shall be responsible for all damage or injury to
the demised premises or any other part of the building and the systems and
equipment thereof, whether requiring structural or nonstructural repairs caused
by or resulting from carelessness, omission, neglect or improper conduct of
Tenant, Tenant's subtenants, agents, employees, invitees or licensees, or
which arise out of any work, labor, service or equipment done for or supplied
to Tenant or any subtenant or arising out of the installation, use or operation
of the property or equipment of Tenant or any subtenant. Tenant shall also
repair all damage to the building and the demised premises caused by the moving
of Tenant's fixtures, furniture and equipment. Tenant shall promptly make, at
Tenant's expense, all repairs in and to the demised premises for which Tenant
is responsible, using only the contractor for the trade or trades in question,
selected from a list of at least two contractors per trade submitted by Owner.
Any other repairs in or to the building or the facilities and systems thereof
for which Tenant is responsible shall be performed by Owner at the Tenant's
expense. Owner shall maintain in good working order and repair the exterior and
the structural portions of the building, including the structural portions of
its demised premises, and the public portions of the building interior and the
building plumbing, electrical, heating and ventilating systems (to the extent
such systems presently exist) serving the demised premises. Tenant agrees to
give prompt notice of any defective condition in the premises for which Owner
may be responsible hereunder. There shall be no allowance to Tenant for
diminution or rental value and no liability on the part of Owner by reason of
inconvenience, annoyance or injury to business arising from Owner or others
making repairs, alterations, additions or improvements in or to any portion of
the building or the demised premises or in and to the fixtures, apportenances
or equipment thereof. It is specifically agreed that Tenant shall not be
entitled to any setoff or reduction of rent by reason of any failure of Owner
to comply with the covenants of this or any other article of this Lease. Tenant
agrees that Tenant's sole remedy at law in such instance will be by way of an
action for damages for breach of contract. The provisions of this Article 4
shall not apply in the case of fire or other casualty which are dealt with in
Article 9 hereof.

        WINDOW CLEANING:  5. Tenant will not clean nor require, permit, suffer
or allow any window in the demised premises to be cleaned from the outside in
violation of Section 202 of the Labor Law or any other applicable law or of the
Rules of the Board of Standards and Appeals, or of any other Board or body
having or asserting jurisdiction.

        REQUIREMENTS OF LAW, FIRE INSURANCE, FLOOR LOADS:  6. Prior to the
commencement of the lease term, if Tenant is then in possession, and at all
times thereafter, Tenant, at Tenant's sole cost and expense, shall promptly
comply with all present and future laws, orders and regulations of all state,
federal, municipal and local governments, departments, commissions and boards
and any direction of any public officer pursuant to law, and all orders, rules
and regulations of the New York Board of Fire Underwriters, Insurance Services
Office, or any similar body which shall impose any violation, order or duty
upon Owner or Tenant with respect to the demised premises, whether or not
arising out of Tenant's use or manner of use thereof, (including Tenant's
permitted use) or, with respect to the building if arising out of Tenant's   
        
        















<PAGE>   2
use or manner of use of the premises or the building (including the use
permitted under the lease). Nothing herein shall require Tenant to make
structural repairs or alterations unless Tenant has, by its manner of use of
the demised premises or method of operation therein, violated any such laws,
ordinances, orders, rules, regulations or requirements with respect thereto.
Tenant may, after securing Owner to Owner's satisfaction against all damages,
interest, penalties and expenses, including, but not limited to, reasonable
attorney's fees, by cash deposit or by surety bond in an amount and in a
company satisfactory to Owner, contest and appeal any such laws, ordinances,
orders, rules, regulations or requirements provided same is done with all
reasonable promptness and provided such appeal shall not subject Owner to
prosecution for a criminal offense or constitute a default under any lease or
mortgage under which Owner may be obligated, or cause the demised premises or
any part thereof to be condemned or vacated. Tenant shall not do or permit any
act or thing to be done in or to the demised premises which is contrary to law,
or which will invalidate or be in conflict with public liability, fire or other
policies of insurance at any time carried by or for the benefit of Owner with
respect to the demised premises or the building of which the demised premises
form a part, or which shall or might subject Owner to any liability or
responsibility to any person or for property damage. Tenant shall not keep
anything in the demised premises except as now or hereafter permitted by the
Fire Department, Board of Fire Underwriters, Fire Insurance Rating Organization
or other authority having jurisdiction, and then only in such manner and such
quantity so as not to increase the rate for fire insurance applicable to the
building, nor use the premises in a manner which will increase the insurance
rate for the building or any property located therein over that in effect prior
to the commencement of Tenant's occupancy. Tenant shall pay all costs,
expenses, fines, penalties, or damages, which may be imposed upon Owner by
reason of Tenant's failure to comply with the provisions of this article and if
by reason of such failure the fire insurance rate shall, at the beginning of
this lease or at any time thereafter, be higher than it otherwise would be,
then Tenant shall reimburse Owner, as additional rent hereunder, for that
portion of all fire insurance premiums thereafter paid by Owner which shall
have been charged because of such failure by Tenant. In any action or
proceeding wherein Owner and Tenant are parties, a schedule or "make-up" of
rate for the building or demised premises issued by the New York Fire Insurance
Exchange, or other body making fire insurance rate applicable to said premises
shall be conclusive evidence of the facts therein stated and of the several
items and charges in the fire insurance rates then applicable to said premises.
Tenant shall not place a load upon any floor of the demised premises exceeding
the floor load per square foot area which it was designed to carry and which is 
allowed by law. Owner reserves the right to prescribe the weight and position
of all safes, business machines and mechanical equipment. Such installations
shall be placed and maintained by Tenant, at Tenant's expense, in settings
sufficient, in Owner's judgement, to absorb and prevent vibration, noise and
annoyance.
        SUBORDINATION:  7.  This lease is subject and subordinate to all ground
or underlying leases and to all mortgages which may now or hereafter affect
such leases or the real property of which demised premises are a part and to
all renewals, modifications, consolidations, replacements and extensions of any
such underlying leases and mortgages. This clause shall be self operative and
no further instrument of subordination shall be required by any ground or
underlying lessor or by any mortgagee, affecting any lease or the real property
of which the demised premises are a part. In confirmation of such
subordination, Tenant shall execute promptly any certificate that Owner may
request.
        PROPERTY--LOSS, DAMAGE, REIMBURSEMENT, INDEMNITY:  8.  Owner or its
agents shall not be liable for any damage to property of Tenant or of others
entrusted to employees of the building, nor for loss of or damage to any
property of Tenant by theft or otherwide, nor for any injury or damage to
persons or property resulting from any cause of whatsoever nature, unless
caused by or due to the negligence of Owner, its agents, servants or employees.
Owner or its agents will not be liable for any such damage caused by other
tenants or persons in, upon or about said building or caused by operations in
construction of any private, public or quasi public work.
        If at any time any windows of the demised premises are temporarily
closed, darkened or bricked up (or permanently closed, darkened or bricked up,
if required by law) for any reason whatsoever including, but not limited to
Owner's own acts, Owner shall not be liable for any damage Tenant may sustain
thereby and Tenant shall not be entitled to any compensation therefor nor
abatement or diminution of rent nor shall the same release Tenant from its
obligations hereunder, nor constitute an eviction. Tenant shall indemnify and
save harmless Owner against and from all liabilities, obligations, damages,
penalties, claims, costs and expenses for which Owner shall not be reimbursed
by insurance, including reasonable attorneys fees, paid, suffered or incurred
as a result of any breach by Tenant, Tenant's agents, contractors, employees,
invitees, or licensees, of any covenant or condition of this lease, or the
carelessness, negligence or unproper conduct of the Tenant, Tenant's agents,
contractors, employees, invitees or licensees. Tenant's liability under this
lease extends to the acts and omissions of any sub-tenant, and any agent,
contractor, employee, invitee or licensee of any sub-tenant. In case any action
or proceeding is brought against Owner by reason of any such claim, Tenant,
upon written notice from owner, will, at Tenant's expense, resist or defend such
action or proceeding by counsel approved by Owner in writing, such approval not
be be unreasonably withheld.

or any part thereof shall be damaged by fire or other casualty, Tenant shall
give immediate notice thereof to Owner and this lease shall continue in full
force and effect except as hereinafter set forth. (b) If the demised premises
are partially damaged or rendered partially unusable by fire or other casualty,
the damages thereto shall be repaired by and at the expense of Owner and the
rent, until such repair shall be substantially completed, shall be apportioned
from the day following the casualty according to the part of the premiss which
is usable.(c) If the demised premises are totally damaged or rendered wholly
unusable by fire or other casualty, then the rent shall be proportionately paid
up to the time of the casualty and thenceforth shall cease until the date when
the premises shall have been repaired and restored by Owner, subject to Owner's
right to elect not to restore the same as hereinafter provided. (d) If the
demised premises are rendered wholly unusable or (whether or not the demised
premises are damaged in whole or in part) if the building shall be so damaged
that Owner shall decide to demolish it or to rebuild it, then, in any of such
events, Owner may elect to terminate this lease by written notice to Tenant,
given within 90 days after such fire or casualty, specifying a date for the
expiration of the lease, which date shall not be more than 60 days after the
giving of such notice, and upon the date specified in such notice the term of
this lease shall expire as fully and completely as if such date were the date
set forth above for the termination of this lease and Tenant shall forthwith
quit, surrender and vacate the premises without prejudice however, to
Landlord's rights and remedies against Tenant under the lease provisions in
effect prior to such termination, and any rent owing shall be paid up to such
date and any payments of rent made by Tenant which were on account of any
period subsequent to such date shall be returned to Tenant. Unless Owner shall
serve a termination notice as provided for herein, Owner shall make the repairs
and restorations under the conditions of (b) and (c) hereof, with all
reasonable expedition, subject to delays due to adjustment of insurance claims,
labor troubles, and causes beyond Owner's control. After any such casualty,
Tenant shall cooperate with Owner's restoration by removing from the premises
as promptly as reasonably possible, all of Tenant's salvageable inventory and
movable equipment, furniture, and other property. Tenant's liability for rent
shall resume five (5) days after written notice from owner that the premises
are substantially ready for Tenant's occupancy. (c) Nothng contained
hereinabove shall relieve Tenant from liability that may exist as a result of
damage from fire or other casualty. Notwithstanding the foregoing, each party
shall look first to any insurance in its favor before making any claim against
the other party for recovery for loss or damage resulting from fire or other
casualty, and to the extent that such insurance is in force and collectible and
to the extent permitted by law. Owner and Tenant each hereby releases and
waives all right of recovery against the other or any one claiming through or
under each of them by way of subrogation or otherwise. The foregoing release
and waiver shall be in force only if both releasors' insurace policies contain
a clause providing that such a release or waiver shall not invalidate the
insurance. If, and to the extent, that such waiver can be obtained only by the
payment of additional premiums, then the party benefitting from the waiver
shall pay such premium within ten days after written demand or shall be deemed
to have agreed that the party obtaining insurance coverage shall be free of any
further obligation under the provisions hereof with respect to waiver of
subrogation. Tenant acknowledges that Owner will not carry insurance on Tenant's
furniture and/or furnishings or any fixtures or equipment, improvements, or
appurtenances removable by Tenant and agrees that Owner will not be obligated
to repair any damage thereto or replace the same. (f) Tenant hereby waives the
provisions of Section 227 of the Real Property law and agrees that the
provisions of this article shall govern and control in lieu thereof.
        EMINENT DOMAIN:  10.  If the whole or any part of the demised premises
shall be acquired or condemned by Eminent Domain for any public or quasi public
use or purpose, then and in that event, the term of this lease shall cease and
terminate from the date of title vesting in such proceeding and Tenant shall
have no claim for the value of any unexpired term of said lease and assigns to
Owner, Tenant's entire interest in any such award. 
        ASSIGNMENT, MORTGAGE, ETC.:  11.  Tenant, for itself, its heirs,
distributees, executors, administrators, legal representatives, successors and
assigns, expressly covenants that it shall not assign, mortgage or encumber
this agreement, nor underlet, or suffer or permit the demised premises or any
part thereof to be used by others, without the prior writen consent of Owner in
each instance. Transfer of the majority of the stock of a corporate 
Tenant shall be deemed an assignment. If this lease be assigned, or if the
demised premises or any part thereof be underlet or occupied by anybody other
than Tenant. Owner may, after defult by Tenant, collect rent from the assignee,
under-tenant or occupant, and apply the net amount collected to the rent herein
reserved, but no such assignment, underletting, occupancy or collection shall
be deemed a waiver of this covenant, or the acceptance of the assignee,
under-tenant or occupant as tenant, or a release of Tenant from the further
performance by Tenant of covenants on the part of Tenant herein contained. The
consent by Owner to an assignment or underletting shall not in any wise be
construed to relieve Tenant from obtaining the express consent in writing of
Owner to any further assignment or underletting.
        ELECTRIC CURRENT:  12.  Rates and conditions in respect to submetering
or rent inclusion, as the case may be, to be added in RIDER attached hereto.
Tenant covenants and agrees that at all times its use of electric current shall
not exceed the capacity of existing feeders to the building or the risers or
wiring installation and Tenant may not use any electrical equipment which, in
Owner's opinion, reasonably exercised, will overload such installations or
interfere with the use thereof by other tenants of the building. The change at
any time of the character of electric service shall in no wise make Owner
liable or responsible to Tenant, for any loss, damages or expenses which Tenant
may sustain.
        ACCESS TO PREMISES:  13.  Owner or Owner's agents shall have the right
(but shall not be obligated) to enter the demised premises in any emergency at
any time, and, at other reasonable times, to examine the same and to make such
repairs, replacements and improvements as Owner may deem necessary and
reasonably desirable to the demised premises or to any other portion of the
building or which Owner may elect to perform. Tenant shall permit Owner to use
and maintain and replace pipes and conduits in and through the demised premises
and to erect new pipes and conduits therein privided they ar conealed within the
walls, floor, or ceiling. Owner may, during the progress of any work in the
demised premises, take all necessary materials and equipment into said premises

any abatement of rent while such work is in progress nor to any damages by
reason of loss or interuption of business or otherwise. Throughout the term
herof Owner shall have the right to enter the demised premises at reasonable
hours for the purpose of showing the 
<PAGE>   3

last six months of the term for the purpose of showing the same to prospective
tenants. If Tenant is not present to open and permit an entry into the
premises. Owner or Owner's agents may enter the same whenever such entry may be
necessary or permissible by master key or forcibly and provided reasonable care
is exercised to safeguard Tenant's property, such entry shall not render Owner
or its agents liable therefor, nor in any event shall the obligations of Tenant
hereunder be affected. If during the last month of the term Tenant shall have
removed all or substantially all of Tenant's property therefrom. Owner may
immediately enter, alter, renovate or redecorate the demised premises without
limitation or abatement of rent, or incurring liability to Tenant for any
compensation and such act shall have no effect on this lease or Tenant's
obligations hereunder.

        VAULT, VAULT SPACE, AREA:  14.  No Vaults, vault space or area, whether
or not enclosed or covered, not within the property line of the building is
leased hereunder, anything contained in or indicated on any sketch, blue print
or plan, or anything contained elsewhere in this lease to the contrary

property line of the building. All vaults and vault space and all such areas
not within the property line of the building, which Tenant may be permitted to
use and/or occupy, is to be used and/or occupied under a revocable license, and
if any such license be revoked, or if the amount of such space or area be
diminished or required by any federal, state or municipal authority or public
utility, Owner shall not be subject to any liability nor shall Tenant be
entitled to any compensation or diminution or abatement of rent, nor shall such
revocation, diminution or requisition be deemed constructive or actual
eviction. Any tax, fee or charge of municipal authorities for such vault or
area shall be paid by Tenant.
        
        OCCUPANCY:  15.  Tenant will not at any time use or occupy the demised
premises in violation of the certificate of occupancy issued for the building
of which the demised premises are a part. Tenant has inspected the premises and
accepts them as is, subject to the riders annexed hereto with respect to
Owner's work, if any. In any event, Owner makes no representation as to the
condition of the premises and Tenant agrees to accept the same subject to
violations, whether or not of record.

        BANKRUPTCY:  16.  (a) Anything elsewhere in this lease to the contrary
notwithstanding, this lease may be cancelled by Owner by the sending of a
written notice to Tenant within a reasonable time after the happening of any
one or more of the following events: (1) the commencement of a case in
bankruptcy or under the laws of any state naming Tenant as the debtor; or (2)
the making by Tenant of an assignment or any other arrangement for the benefit
of creditors under any state statute. Neither Tenant nor any person claiming
through or under Tenant, or by reason of any statute or order of court, shall
thereafter be entitled to possession of the premises demised but shall
forthwith quit and surrender the premises. If this lease shall be assigned in
accordance with its terms, the provisions of this Article 16 shall be
applicable only to the party then owning Tenant's interest in this lease.

        (b) it is stipulated and agreed that in the event of the termination of
this lease pursuant to (a) hereof, Owner shall forthwith, notwithstanding any
other provisions of this lease to the contrary, be entitled to recover from
Tenant as and for liquidated damages an amount equal to the difference between
the rent reserved hereunder for the unexpired portion of the term demised and
the fair and reasonable rental value of the demised premises for the same
period. In the computation of such damages the difference between any
installment of rent becoming due hereunder after the date of termination and
the fair and reasonable rental value of the demised premises for the period for
which such installment was payable shall be discounted to the date of
termination at the rate of four percent (4%) per annum. If such premises or any
part thereof be relet by the Owner for the unexpired term of said lease, or any
part thereof, before presentation of proof of such liquidated damages to any
court, commission or tribunal, the amount of rent reserved upon such reletting
shall be deemed to be the fair and reasonable rental value for the part or the
whole of the premises so re-let during the term of the re-letting. Nothing
herein contained shall limit or prejudice the right of the Owner to prove for
and obtain as liquidated damages by reason of such termination, an amount
equal to the maximum allowed by any statute or rule of law in effect at the
time when, and governing the proceedings in which, such damages are to be
proved, whether or not such amount be greater, equal to, or less than the
amount of the difference referred to above.

covenants of this lease other than the covenants for the payment of rent or
additional rent; or if the demised premises becomes vacant or deserted; or if

property whereupon the demised premises shall be taken or occupied by someone
other than Tenant; or if this lease be rejected under Section 235 of Title 11
of the U.S. Code (bankruptcy code); or if Tenant shall fail to move into or
take possession of the premises within fifteen (15) days after the commencement
of the term of this lease, then, in any one or more of such events, upon Owner
serving a written five (5) days notice upon Tenant specifying the nature of
said default and upon the expiration of said five (5) days, if Tenant shall
have failed to comply with or remedy such default, or if the said default or
omission complained of shall be of a nature that the same cannot be completely
cured or remedied within said five (5) day period, and if Tenant shall not
have dilengently commenced during such default within such five (5) day
period, and shall not thereafter with reasonable diligence and in good faith,
proceed to remedy or cure such default, then Owner may serve a written three (3)
days' notice of cancellation of this lease upon Tenant, and upon the expiration
of said three (3) days this lease and the term thereunder shall end and expire
as fully and completely as if the expiration of such three (3) day period were
the day herein definitely fixed for the end and expiration of this lease and
the term thereof and Tenant shall then quit and surrender the demised premises
to Owner but Tenant shall remain liable as hereinafter provided.

        (2) If the notice provided for in (1) hereof shall have been given, and
the term shall expire as aforesaid: or if Tenant shall make default in the
payment of the rent reserved herein or any item of additional rent herein
mentioned or any part of either or in making any other payment herein required;
then and in any of such events Owner may without notice, re-enter the demised
premises either by force or otherwise, and dispossess Tenant by summary
proceedings or otherwise, and the legal representative of Tenant or other
occupant of demised premises and remove their effects and hold the premises as
if this lease had not been made, and Tenant hereby waives the service of notice
of intention to re-enter or to institute legal proceedings to that end. If
Tenant shall make default hereunder prior to the date fixed as the commencement
of any renewal or extension of this lease, Owner may cancel and terminate such
renewal or extension agreement by written notice.


        REMEDIES OF OWNER AND WAIVER OF REDEMPTION:  18.  In case of any such
default, re-entry, expiration and/or dispossess by summary proceedings or
otherwise, (a) the rent shall become due thereupon and be paid up to the time
of such re-entry, dispossess and/or expiration, (b) Owner may re-let the
premises or any part of parts thereof, either in the name of Owner or
otherwise, for a term or terms, which may at Owner's option be less than or
exceed the period which would otherwise have constituted the balance of the
term of this lease and may grant concessions or free rent or charge a higher
rental than that in this lease, and/or (c) Tenant or the legal representatives
of Tenant shall also pay Owner as liquidated damages for the failure of Tenant
to observe and perform said Tenant's covenants herein contained, any
deficiency between the rent hereby reserved and/or covenanted to be paid and
the net amount, if any, of the rents collected on account of the lease or
leases of the demised premises for each month of the period which would
otherwise have constituted the balance of the term of this lease. The failure
of Owner to re-let the premises or any part or parts thereof shall not release
or affect Tenant's liability for damages. In computing such liquidated damages
there shall be added to the said deficiency such expenses as Owner may incur in
connection with re-letting, such as legal expenses, attorneys' fees, brokerage,
advertising and for keeping the demised premises in good order or for preparing
the same for re-letting. Any such liquidated damages shall be paid in monthly
installments by Tenant on the rent day specified in this lease and any suit
brought to collect the amount of the deficiency for any month shall not
prejudice in any was the rights of Owner to collect the deficiency for any
month shall not prejudice in any way the rights of Owner to collect the
dificiency of any subsequent month by a similar proceeding. Owner, in putting
the demised premises in good order or preparing the same for re-rental may, at
Owner's option, make such alterations, repairs, replacements, and/or
decorations in the demised premises as Owner, in Owner's sole judgment,
considers advisable and necessary for the purpose of re-letting the demised
premises, and the making of such alterations, repairs, replacements, and/or
decorations shall not operate or be construed to release Tenant from liability
hereunder as aforesaid. Owner shall in no event be liable in any way whatsoever
for failure to re-let the demised premises, or in the event that the demised
premises are re-let, for failure to collect the rent thereof under such
re-letting, and in no event shall Tenant be entitled to receive any excess, if
any, of such net rents collected over the sums payable by Tenant to Owner
hereunder. In the event of a breach or threatened breach by Tenant of any of
the covenants or provisions hereof, Owner shall have the right of injunction
and the right to invoke any remedy allowed at law or in equity as if re-entry,
summary proceedings and other remedies were not herein provided for. Mention
in this lease of any particular remedy, shall not preclude Owner from any other
remedy, in law or in equity. Tenant hereby expressly waives any and all rights
of redemption granted by or under any present or future laws in the event of
Tenant being evicted or dispossessed for any cause, or in the event of Owner
obtaining possession of demised premises, by reason of the violation by Tenant
of any of the covenants and conditions of this lease, or otherwise.


        FEES AND EXPENSES  19.  If Tenant shall default in the obvservance or
performance of any term or covenant on Tenant's part to be observed or
performed under or by virtue of any of the terms or provisions in any article
of this lease, then, unless otherwise provided elsewhere in this lease, Owner
may immediately or at any time thereafter and without notice perform the
obligation of Tenant thereunder. If Owner, in connection with the foregoing or
in connection with any default by Tenant in the covenant to pay rent hereunder,
makes any expenditures or incurs any obligations for the payment of money, 
including but not limited to attorney's fees, in instituting, prosecuting or
defending any action or proceeding, then Tenant will reimburse Owner for such
sums so paid or obligations incurred with interest and costs. The foregoing
expenses incurred by reason of Tenant's default shall be deemed to be
additional rent hereunder and shall be paid by Tenant to Owner within five (5)
days of rendition of any bill or statement to Tenant therefor. If Tenant's
lease term shall have expired at the time of making of such expenditures or
incurring of such obligations, such sums shall be recoverable by Owner as
damages.


        BUILDING ALTERATIONS AND MANAGEMENT:  20.  Owner shall have the right
at any time without the same constituting an eviction and without incurring
liability to Tenant therefor to change the arrangement and/or location of
public entrances, passageways, doors, doorways, corridors, elevators, stairs,
toilets or other public parts of the building and to change the name, number or
designation by which the building may be known. There shall be no allowance to
Tenant for dimunition of rental value and no liability on the part of Owner by
reason of inconvenience, annoyance or injury to business arising from Owner or
other Tenants making any repairs in the building or any such alterations,
additions and improvements. Furthermore, Tenant shall not have any claim
against Owner by reason of Owner's imposition of such controls of the manner of
access to the building by Tenant's social or business visitors as the Owner may
deem necessary for the security of the building and its occupants.      


        NO REPRESENTATIONS BY OWNER:  21.  Neither Owner nor Owner's agents 
have made any representations or promises with respect to the physical 
condition of the building, the land upon which

operation or any other matter or thing affecting or related to the premises
except as herein expressly set forth and no rights, easements or licenses are
acquired by Tenant by implication or otherwise except as expressly set forth in
the provisions of this lease. Tenant has inspected the building and the demised
premises and is thoroughly acquainted with their condition and agrees to take
the same "as is" and acknowledges that the taking of possession of the demised
premises by Tenant shall be conclusive evidence that the said premises and the
building of which the same form a part were in good and satisfactory condition
at the time such possession was so taken, except as to latent defects. All
understandings and agreements heretofore made between the parties hereto are
merged in this contract, which alone fully and completely expresses the
agreement between Owner and Tenant and any executory agreement hereafter made
shall be ineffective to change, modify, discharge or effect an abandonment of
it in whole or in part, unless such executory agreement is in writing and
signed by the party against whom enforcement of the change, modification,
discharge or abandonment is sought.

        END OF TERM:  22. Upon the expiration or other termination of the term
of this lease, Tenant shall quit and surrender to Owner the demised premises,
broom clean, in good order and condition, ordinary wear and damages which
Tenant is not required to repair as provided elsewhere in this lease excepted,
and Tenant shall remove all its property. Tenant's obligation to observe or
perform this covenant shall survive the expiration or other termination of
this lease. If the last day of the term of this Lease or any renewal therof,
falls on Sunday, this lease shall expire at noon on the preceding Saturday
unless it be a legal holiday in which case it shall expire at noon on the
preceding business day.

        QUIET ENJOYMENT:  23.  Owner covenants and agrees with Tenant that
upon Tenant paying the rent and additional rent and observing and performing
all the terms, covenants and conditions, on Tenant's part to be observed and 
performed, Tenant may peaceably and quietly enjoy the premises hereby demised, 
subject, nevertheless, to the terms and conditions of this lease including,
but not limited to, Article 30 hereof and to the ground leases, underlying 
leases and mortgages hereinbefore mentioned.

        FAILURE TO GIVE POSSESSION:  24.  If Owner is unable to give
possession of the demised premises on the date of the commencement of the term 
hereof, because of the holding-over or retention of possession of any tenant, 
undertenant or occupants or if the demised premises are located in a building 
being constructed, because such building has not been sufficiently completed 
to make the premises ready for occupancy or because of the fact that a 
certificate of occupancy has not been procured or for any other reason, Owner 
shall not be subject to any liability for failure to give possession on said 
date and the validity of the lease shall not be impaired under such 
circumstances, nor shall the same be construed in any wise to extend the term 
of this lease, but the rent payable hereunder shall be abated (provided Tenant 
is not responsible for Owner's inability to obtain possession) until after 
Owner shall have given Tenant written notice that the premises are 
substantially ready for Tenant's occupancy. If permission is given to Tenant 
to enter into the possession of the demised premises or to occupy premises 
other than the demised premises prior to the date specified as the 
commencement of the term of this lease, Tenant covenants and agrees that such 
occupancy shall be deemed to be under all the terms, covenants, conditions 
and provisions of this lease, except as to the covenant to pay rent. The 
provisions of this article are intended to constitute "an express provision 
to the contrary" within the meaning of Section 223-a of the New York 
Real Property Law.

        NO WAIVER:  25.  The failure of Owner to seek redress for violation 
of, or to insist upon the strict performance of any covenant or condition of 
this lease or of any of the Rules or Regulations, set forth or hereafter 
adopted by Owner, shall not prevent a subsequent act which would have 
originally constituted a violation from having all the force and effect of an 
original violation. The receipt by Owner of rent with knowledge of the breach 
of any covenant of this lease shall not be deemed a waiver of such breach and 
no provision of this lease shall be deemed to have been waived by Owner unless 
such waiver be in writing signed by Owner. No payment by Tenant or receipt by 
Owner of a lesser amount than the monthly rent herein stipulated shall be 
deemed to be other than on account of the earliest stipulated rent, nor shall 
any endorsement or statement of any check or any letter accompanying any check 
or payment as rent be deemed an accord and satisfaction, and Owner may accept
such check or payment without prejudice to Owner's right to recover 
the balance of such rent or pursue any other remedy in this lease provided. 
No act or thing done by Owner or Owner's agents during the term hereby demised 
shall be deemed an acceptance of a surrender of said premises, and no 
agreement to accept such surrender shall be valid unless in writing signed by 
Owner. No employee of Owner or Owner's agent shall have any power to accept 
the keys of said premises prior to the termination of the lease and the 
delivery of keys to any such agent or employee shall not operate as a 
termination of the lease or a surrender of the premises.

        WAIVER OF TRIAL BY JURY:  26.  It is mutually agreed by and between 
Owner and Tenant that the respective parties hereto shall and they hereby do 
waive trial by jury in any action, proceeding or counter-claim brought by 
either of the parties hereto against the other (except for personal injury or 
property damage) on any matters whatsoever arising out of or in any way 
connected with this lease, the relationship of Owner and Tenant, Tenant's use 
of or occupancy of said premises, and any emergency statutory or any other 
statutory remedy. It is further mutually agreed that in the event Owner 
commences any summary proceeding for possession of the premises, Tenant will 
not interpose any counterclaim of whatever nature or description in any such 
proceding including a counterclaim under Article 4.

        INABILITY TO PERFORM:  27.  This Lease and the obligation of Tenant to 
pay rent hereunder and perform all of the other covenants and agreements 
hereunder on part of Tenant to be performed shall in no wise be affected, 
impaired or excused because Owner is unable to fulfill any of its obligations 
under this lease or to supply or is delayed in supplying any service 
expressly or impliedly to be supplied or is unable to make, or is delayed in 
making any repair, additions, alterations or decorations or is unable to 
supply or is delayed in supplying any equipment or fixtures if Owner is 
prevented or delayed from so doing by reason of strike or labor troubles or 
any cause whatsoever including, but not limited to, government preemption in 
connection with a National Emergency or by reason of any rule, order or 
regulation of any department or subdivision thereof of any government agency 
or by reason of the conditions of supply and demand which have been or are 
affected by war or other emergency.

        BILLS AND NOTICES:  28.  Except as otherwise in this lease provided, 
a bill, statement, notice or communication which Owner may desire or be 
required to give to Tenant, shall be deemed sufficiently given or rendered if,
in writing, delivered to Tenant personally or sent by registered or certified 
mail addressed to Tenant at the building of which the demised premises form a 
part or at the last known residence address or business address of Tenant or 
left at any of the aforesaid premises addressed to Tenant, and the time of the
rendition of such bill or statement and of the giving of such notice or
communication shall be deemed to be the time when the same is delivered to
Tenant, mailed, or left at the premises as herein provided. Any notice by
Tenant to Owner must be served by registered or certified mail addressed to
Owner at the address first hereinabove given or at such other address as Owner
shall designate by written notice.

        SERVICES PROVIDED BY OWNERS:  29.  As long as Tenant is not in default 
under any of the covenants of this lease, Owners shall provide: (a) necessary
elevator facilities on business days from 8 a.m. to 6 p.m. and on Saturdays
from 8 a.m. to 1 p.m. and have one elevator subject to call at all other times;

from 8 a.m. to 6 p.m. and on Saturdays from 8 a.m. to 1 p.m.; (c) water for

thereafter maintain at Tenant's expense in good working order and repair to
register such water consumption and Tenant shall pay for water consumed as
shown on said meter as additional rent as and when bills are rendered; (d)
cleaning service for the demised premises on business days at Owner's expense
provided that the same are kept in order by Tenant. If, however, said premises
are to be kept clean by Tenant, it shall be done at Tenant's sole expense, in a
manner satisfactory to Owner and no one other than persons approved by Owner
shall be permitted to enter said premises or the building of which they are a
part for such purpose. Tenant shall pay Owner the cost of removal of any of
Tenant's refuse and rubbish from the building; (e) if the demised premises is
serviced by Owner's air conditioning/cooling and ventilating system, air

September 30th on business days (Mondays through Fridays, holidays excepted)
from 8:00 a.m. to 6:00 p.m., and ventilation will be furnished on business days
during the aforesaid hours except when air conditioning/cooling is being
furnished as aforesaid. If Tenant requires air conditioning/cooling or
ventilation for more extended hours or on Saturdays, Sundays or on holidays, as
defined under Owner's contract with Operating Engineers Local 94-94A, Owner
will furnish the same at Tenant's expense. RIDER to added in respect to rates
and conditions for such additional service; (f) Owner reserves the right to
stop services of the heating, elevators, plumbing, air-conditioning, power
systems or cleaning or other services, if any, when necessary by reason of
accident or for repairs, alterations, replacements or improvements necessary or
desirable in the judgment of Owner for as long as may be reasonably required by
reason thereof. If the building of which the demised premises are a part
supplies manually-operated elevator service, Owner at any time may substitute
automatic-control elevator service and upon ten days' written notice to Tenant,
proceed with alterations necessary therefor without in any wise affecting this
lease or the obligation of Tenant hereunder. The same shall be done with a
minimum of inconvenience to Tenant and Owner shall pursue the alteration with
due diligence.

         The laws of the State of New York shall govern the validity,
performance, and enforcement of this Lease. The invalidity or unenforceability
of any provision of this Lease shall not affect or impair any other provision.
If any provision of this Lease is capable of two constructions, one of which
would render the provision invalid and the other of which would make the
provision valid, then the provision shall have the meaning which renders it

Landlord and Tenant.

R4.

         If electric current is supplied by Landlord, Tenant shall purchase the
same from the Landlord or Landlord's agent at a base rate consisting of the
charges, terms and rates for like quantities and character of service in the
Consolidated Edison service classification in effect at the time said service is
used and under which the Landlord purchases service (plus 15%).

         In addition, Tenant shall pay to Landlord 6.25% of each electric bill
received by Landlord from the public utility corporation, as additional rent, to
recompense Landlord for the cost of lighting all of the public and service areas
of the building and in administering and operating all of the electrical service
and mechanical facilities of the building.

         At the option of Landlord, Tenant also agrees to purchase from Landlord
or its agent all lamps of bulbs used in the demised premises and to pay for cost
of installation thereof. Landlord shall not be liable to Tenant for any loss or
damage or expense which Tenant may sustain or incur if either the quantity or
character of electric service is changed or is no longer available or suitable
for Tenant's electrical requirements. Any riser or risers to supply Tenant's
electrical requirements, upon written request of Tenant, will be installed by
Landlord, at the sole cost and expense of Tenant, if, in Landlord's sole
judgment, the same will not cause permanent damage or injury to the building or
demised premises or cause or create a dangerous or hazardous condition or entail
excessive or unreasonable alterations, repairs or expense or interfere with or
disturb other tenants or occupants. In addition to the installation of such
riser or risers, Landlord will also at the sole cost and expense of Tenant,
install all other equipment proper and necessary in connection therewith subject
to the aforesaid terms and conditions. Tenant

                                        1

covenants and agrees that at all times its use of electric current shall never
exceed the capacity of existing feeders to the building or the risers of wiring
installations.

         Bills shall be rendered at such times as Landlord may elect. In the
event that such bills are not paid within ten (10) days after they are rendered,
Landlord may, without further notice, discontinue the service of electric
current to the demised premises. Landlord may also discontinue the service of
electric current to the demised premises without cause upon thirty (30) days
notice to Tenant if Landlord so elects to discontinue submetering service. In
the event of discontinuance of electric service by the Landlord, Tenant shall
not be released from any liability under this Lease, and Landlord shall not
incur any liability for any loss or damage sustained by Tenant by such
discontinuance. Such discontinuance shall not be deemed to be a lessening of
services within the meaning of any law, rule, or regulation now or hereafter
enacted, promulgated or issued. In the event of such discontinuance, Landlord
shall permit Tenant to receive such service directly from said public utility
corporation, in which event, the Tenant will, at its own cost and expense,
furnish and install all risers, service wiring, and switches that may be
necessary for such installation and required by the public utility company, and
will at its own cost and expense, maintain and keep in good repair all such
risers, wiring and switches. Tenant shall make no alteration or additions to the
electric equipment and/or appliances without the prior written consent of
Landlord in each instance. Rigid conduit only will be allowed.

         If any tax is imposed upon Landlord's receipt from the sale or resale
of electrical energy to the Tenant by any Federal, State or Municipal Authority,
Tenant covenants and agrees that, where permitted by law, Tenant's pro-rata
share of such taxes shall be passed on to, and included in the bill of, and paid
by, Tenant to Landlord.

         In addition to the paying of rent reserved hereunder the Tenant
covenants and agrees that if the price of #6 fuel oil used in the operation of
the building of which the demised are a part of exceed 50 cents per gallon, then
the annual rental to be paid by the Tenant shall be increased by multiplying
7500 by one (1) cent per gallon of increase. Such increase in cost as to each
year shall be based on the average per gallon cost of the fuel oil delivered to
the premises, including any and all City, State and Federal taxes, surcharges
and adjustments, during the month of February 1992, and each February,
thereafter, during the term of this lease as same is billed to Landlord by the
oil supplier. Such annual additional rent shall be due and payable on the first
day of April in each year. The obligation to make any payment pursuant to this
clause shall survive the expiration or other termination of this lease. In the
event that the buildings heating system is altered or changed to an alternative
fuel supply such as gas, #2 or #4 oil, then it is understood and agreed that the
provisions of the clause shall survive such alteration or conversion. Upon
demand by Tenant, however, the Landlord agrees to submit to Tenant copies of
fuel bills or accountants statement covering same.

governmental authority.

         C. Base Tax Year shall mean the Tax Year 1991/92

         D. Tenant shall pay, as additional rent, six & one quarter percent

levied, assessed or imposed at any time by the City of New York or by any other
governmental authority upon or against the land and/or building of which the
demised premises form a part, and also any tax or assessment levied, assessed or

income, transit, profit or other tax, fee, or governmental imposition, however
designated, shall be levied, assessed or imposed against Landlord in
substitution, in whole or in part, for the said real estate taxes, or in lieu of

included within the definition of "real estate taxes" for the purposes hereof.

         G. Any delay or failure of Landlord in billing any amount payable under
this Article shall not constitute a waiver or in any way impair the continuing
obligation of Tenant to make all payments hereunder.

R7.

         A. Tenant, at its sole cost and expense, shall maintain at all times
during the term of this lease and at all times when Tenant is in possession of
the demised premises, a comprehensive policy of general liability insurance in
which Landlord, Landlord's managing agent, any Superior Lessor (as hereinafter
defined), any mortgagees designated by Landlord, and Tenant, are the named
insureds, for any and all claims arising during the term of this lease for
damages or injuries to goods, wares, merchandise and property and/or for any
personal injury or loss of life, in, upon or about the demised premises;
protecting Landlord, Landlord's managing agent, any Superior Lessor, any
mortgagees designated by Landlord, and Tenant against any liability whatsoever
occasioned by accidents on or about the demised premises or any appurtenances
thereto. Such policy is to be written by a good and solvent insurance company,
satisfactory to Landlord, in the amount of ONE MILLION AND 00/100--
($1,000,000.00)--DOLLARS per occurrence (combined single limit), TWO MILLION AND
00/100 ($2,000,000.00) DOLLARS IN aggregate. Tenant agrees to deliver to
Landlord a certificate of endorsement of the aforesaid insurance policy and upon
Tenant's failure to provide and keep in force the aforementioned insurance, it
shall be regarded as a material default, entitling Landlord to exercise any or
all of the remedies as provided in this Lease.

         B. Tenant shall deliver to Landlord such policies or certificates of
such policies prior to the commencement of the term of this lease. Tenant shall
procure and pay for renewals of such insurance from time to time before the
expiration thereof, and Tenant shall deliver to Landlord and any additional
named insureds such renewal policy or certificate at least thirty (30) days
before the expiration of any existing policy. All such policies shall be for a
period of not less than one year and shall contain a provision.


                                        3
<PAGE>   8
whereby the same cannot be cancelled or modified unless Landlord and any
additional named insureds are given at least thirty (30) days prior written
notice of such cancellation or modification, including, without limitation, any
such cancellation resulting from the nonpayment of premiums. If Building
Mortgagee or Tenant's insurance carrier so requires, Landlord shall have the
right to require Tenant to increase the amount of the insurance maintained by
Tenant under this Article, so that the amount thereof, adequately protects the
interest of Landlord.

         C. Tenant shall secure an appropriate clause in, or an endorsement
upon, each insurance policy obtained by it and covering or applicable to the
demised premises or the personal property, fixtures, and equipment located
therein or thereon, pursuant to which the insurance company waives subrogation
or permits the insured, prior to any loss, to agree with a third party to waive
any claim it might have against said third party without invalidating the
coverage under the insurance policy. The waiver of subrogation or permission for
waiver of any claim shall extend to Landlord and its agents and their respective
employees.

         D. Tenant shall also obtain, at its own cost and expense, naming both
Landlord, Landlord's managing agent, any Superior Lessor, any mortgagees
designated by Landlord, and Tenant as named insureds, fire insurance for all
personal property which may be affixed to the realty now located in the lease
premises and including any future installations.

         E. Notwithstanding anything herein to the contrary, nothing herein
shall prevent Landlord from recovering in the event of fire or other loss under
Landlord's fire or other insurance coverage for all betterments and improvements
by Tenant so affixed to the demised premises as to be considered part of the
realty under law.

         F. Tenant hereby releases Landlord, Landlord's partners or principals,
disclosed or undisclosed, and its agents and their respective employees in
respect to any claim occurring during the term of this lease and normally
covered under a fire insurance policy with extended coverage endorsement in the
form normally used in respect to similar property in New York County. This
waiver shall include any claim which Tenant might otherwise have against
Landlord, Landlord's partners or principals, disclosed or undisclosed, and its
agents and their employees for loss, damage or destruction with respect to
Tenant's property by fire or other casualty (including rental value or business
interest, as the case may be).

R8.

         For the purposes of this Article only, the following words and terms
shall have the following meanings:

         (i) "RAB Labor Rate" shall mean the minimum regular hourly wage rate
prescribed for Elevator Operators in Class A Loft Buildings in effect on January
1st of the Base Year or any Comparison Year pursuant to an agreement between the
Realty Advisory Board on Labor Relations, Incorporated, hereinafter referred to
as RAB (or any successor thereto) and Local 32B of the Building Service
Employees International Union, AFL-CIO for any successor thereto) provided,
however, that if in any year during the term of this lease regular employment
of Elevator Operators shall occur on days or during hours when overtime or other
premium pay rates are in effect pursuant to such agreement, then the term
"regular hourly wage rate" as used in this Article shall be deemed to mean the
average hourly wage rate for the hours in a calendar week during which Elevator
Operators are regularly employed (e.g., if, as of January 1st, 1975, pursuant to
an agreement between RAB and Local 32B the regular employment of Elevator
Operators for 40 hours during a calendar week is at a regular hourly wage rate
of $3.00 for the first thirty hours, and premium or overtime hourly wage rate of
$4.58 for the remaining 10 hours then the regular hourly wage rate under this
Article, as of January 1st, 1975, shall be the total weekly wage rate of $135
divided by the total number of regular hours of employment forty, or $3.375);
and provided, however, that if there is no such agreement in effect as of any
such January 1st, "RAB Labor Rate" shall mean the minimum regular


                                        4
<PAGE>   9
hourly wage rate actually payable to Elevator Operators by landlords of such
buildings and appropriate retroactive adjustment shall thereafter be made when
the minimum regular hourly wage rate pursuant to such agreement is finally
determined.

         (ii) "Base Year" shall mean the calendar year 1992.

         (iii) "Comparison Year" shall mean each calendar year, subsequent to
the Base Year, in which occurs any part of the term hereof.

         (iv) "Wage rate Multiple" shall mean the figure, "7500".

         (v) "Elevator Operators" shall mean the classification of employee
engaged in the operation of elevators in Class A Loft Buildings most nearly
comparable to that classification now applicable to elevator operators in the
current agreements between RAB and Local 32B (which classification is presently
termed "others" in said agreements).

If for any Comparison Year, the RAB Labor Rate shall be increased over the RAB
Labor Rate for the Base Year, Tenant shall pay to Landlord as additional annual
rent an amount equal to the product obtained by multiplying the Wage Rate
Multiple by 1 the number of cents of such increase, such payment to be made in
equal monthly installments commencing with the first monthly installment of rent
falling due on or after the effective date of such increase and continuing
thereafter until a new adjustment shall have become effective in accordance with
the provisions of this Article. Landlord shall give Tenant written notice of
each change in the RAB Labor Rate which will be effective to create or change
Tenant's obligation to pay additional rent pursuant to the provisions of this
Article. If said notice be given to Tenant after the commencement of a
Comparison Year then Tenant shall within ten (10) days after the giving thereof
pay to Landlord such additional rent for any months in such Comparison Year
which shall have elapsed prior to the giving of such notice. The additional rent
due pursuant to the provisions of this Article shall be collectible by Landlord
in the same manner as annual rent. The obligation to make any payments pursuant
to this article shall survive the expiration or other termination of this lease.

R9.

         Tenant, at its own cost and expense, shall arrange for the removal of
all rubbish from the demised premises and from the Building in accordance with
any and all applicable municipal codes and regulations and in accordance with
any rules and regulations of the Building which, in the judgment of Landlord,
are necessary for the proper operation of the Building.

R10.

         Tenant shall look only to Landlord's estate and property in the
Building for the satisfaction of Tenant's remedies for the collection of a
judgment (or other judicial process) requiring the payment of money by Landlord
in the event of any default or breach by Landlord hereunder, and no other
property or assets of Landlord or its partners or principals, disclosed or
undisclosed, shall be subject to lien, levy, execution or other enforcement
procedure for the satisfaction of Tenant's remedies under or with respect to
this Lease, the relationship of Landlord and Tenant hereunder or Tenant's use or
occupancy of the demised premises; and if Tenant shall acquire a lien on such
other property or assets by judgment or otherwise, Tenant shall promptly release
such lien by executing and delivering to Landlord an instrument to that effect
prepared by Landlord.

R11.

         Tenant shall and hereby does waive its right and agrees not to
interpose any counterclaim or set off, of whatever nature or description, in any
proceedings or action which may be constituted by Landlord against Tenant to
recover rent, additional rent, other charges, or for damages, or for any breach
of this Lease whatsoever, or any renewal,


                                        5
<PAGE>   10
extension, holdover, or modification thereof, the relationship of Landlord and
Tenant, or Tenant's use or occupancy of said premises. This clause, as well as
the "waiver of jury trial" provision of this Lease, shall survive the
expiration, early termination, or cancellation of this Lease or the term
thereof. Nothing herein contained, however, shall be construed as a waiver of
Tenant's right to commence a separate action on a bonafide claim against
Landlord.

R12.

         If Tenant is in arrears in payment of rent or additional rent, Tenant

apply any payments made by Tenant to any items Landlord sees fit, irrespective
of and notwithstanding any designation or request by Tenant as to the items
against which any such payments shall be credited.

Landlord shall place upon such directory board, as Landlord may from time to
time maintain in the lobby of the Building, one or more names or persons, firms
or corporations other than Tenant, this shall not be deemed to operate as an
attornment or as a consent by Landlord to an assignment or subletting by Tenant
of all or any portion of the demised premises to such persons, firms or
corporations. Landlord reserves the right at all times to limit the number of
listings which Tenant can have on the building directory.

adversely affect the leasehold interest hereby created.

         B. Tenant agrees, at any time and from time to time, as requested by
Landlord, upon not less than ten (10) days prior notice, to execute and deliver

knowledge of Tenant, and, if so, specifying each such default of which Tenant
may have knowledge, and stating whether or not, to the best of knowledge of
Tenant, any event has occurred which with the giving of notice or passage of
time, or both, would constitute such a default, and if so, specifying each such
event, it being intended that any such statement delivered pursuant thereto
shall be deemed a representation and warranty to be relied upon by Landlord and
by other with whom Landlord may be dealing, regardless of independent
investigation.

R15.

         A. Tenant, for itself, its heirs, distributees, executors,
administrators, legal representatives, successors and assigns, expressly
covenants that it shall not assign, or mortgage or otherwise encumber, all or

have been listed or otherwise publicly advertised for assignment or subletting
at a rental rate lower than the higher of (a) the Fixed Annual Rent and all
Additional Rent then payable, or (b) the then prevailing rental rate for other
space in the Building, and Tenant shall not enter into any sublease at a lower
rental rate than the Fixed Annual Rent and all Additional Rent then payable;

            2. Tenant shall not then be in default hereunder beyond the
expiration of any applicable grace period.

            3. The proposed assignee or subtenant shall have a financial

subtenant or assignee of any space in the Building, nor shall the proposed
assignee or subtenant be a person or entity with whom Landlord is then
negotiating to lease space in the Building.

            5. The character of the business to be conducted in the Demised
Premises by the proposed assignee or subtenant shall not substantially increase
Operating Expenses or Building Energy Costs or the burden on existing cleaning
services or elevators in the Building.

            6. In case of a subletting, the subtenant shall be expressly subject
to all of the obligations of Tenant under this Lease and the further condition
and restriction that such sublease shall not be assigned, encumbered or
otherwise transferred or the Demised Premises further sublet by the subtenant in

remainder of the Demised Premises shall in Landlord's judgment constitute
commercially marketable separate rental units.

            10. Tenant shall reimburse Landlord on demand for any reasonable
fees, including attorney's fees and disbursements, that may be incurred by
Landlord in connection with said assignment or sublease.

<PAGE>   12
succeed to Tenant's estate in the Demised Premises, then at Landlord's election
such subtenant shall either surrender the Demised Premises to Landlord within
sixty (60) days of Landlord's request therefore, or shall attorn to and
recognize Landlord as such subtenant's landlord under such sublease, and such
subtenant shall promptly execute and deliver any instrument Landlord may
reasonably request to evidence such attornment.

         E. Tenant shall deliver to Landlord a copy of each sublease or
assignment made hereunder within ten (10) days after the date of its execution.
Tenant shall remain fully liable for t performance of all of Tenant's
obligations hereunder notwithstanding any subletting assignment provided for
herein and, without limiting the generality of the foregoing shall remain fully
responsible and liable to Landlord for all acts and omissions of any subtenant,
assignee or anyone claiming by, through or under any subtenant or assignee which
shall be in violation of any of the obligations of this Lease, and any such
violation shall be deemed to be a violation by Tenant. Notwithstanding any
assignment and assumption by the assignee of the obligations of Tenant
hereunder, Tenant herein named, and each immediate or remote successor in
interest of Tenant herein named, shall remain liable jointly and severally (as a
primary obligor) with its assignee and all subsequent assignees for the
performance of Tenant's obligations hereunder, and shall remain fully and
directly responsible and liable to Landlord for all acts and omissions on the
part of any assignee subsequent to it in violation of any of the obligations of
this Lease.

         F. Notwithstanding anything to the contrary contained in this Lease, no
assignment of Tenant's interest in this Lease shall be binding upon Landlord
unless the assignee, and, if the assignee is a partnership, the individual
partners thereof, shall execute and deliver to Landlord an agreement, in
recordable form, whereby such assignee agrees to perform all of the obligations
of Tenant hereunder and further expressly agrees that notwithstanding such
assignment the provisions of this Article shall continue to be binding upon such
assignee with respect to all future assignments and transfers.

         G. If Tenant shall enter into any assignment, sublease or other
agreement of occupancy permitted under this Lease, of or affecting all or any
portion of the Demised Premises, or if there is any transfer of this Lease by
operation of law or otherwise, and if Tenant shall receive any consideration
from its assignee, subtenant or licensee for or in connection with the
assignment of Tenant's interest in this Lease or the subletting or occupancy of
all or any part of the Denied Premises, as the case may be (including, but not
limited to, sums paid for the sale or rental of Tenant's fixtures, leasehold
improvements, equipment, furniture or other personal property, less, in the case
of a sale thereof, the then net unamortized or undepreciated cost thereof
determined on the basis of Tenant's federal income tax returns) or, if Tenant
shall sublet or otherwise permit occupancy of the Demised Premises at a rental
rate (including additional rent) or other periodic consideration which shall
exceed the Fixed Annual Rent and Additional Rent then payable hereunder, Tenant
shall pay to Landlord, as Additional Rent hereunder, one-half (1/2) of such
consideration or such excess.

         H. Any transfer, by operation of law or otherwise of the interest of
Tenant in this Lease (in whole or in part) or of a fifty (50%) percent or
greater interest in Tenant (whether stock, partnership interest or otherwise)
shall be deemed an assignment of this Lease within the meaning of this Article.
(The issuance of shares of stock to other than the existing shareholders shall
be deemed to be a transfer of such stock for the purposes of this Article.) If
there has been a previous transfer of less than a fifty (50%) percent interest
in Tenant, any other transfer of an interest in Tenant which would then result
in an aggregate transfer of greater than fifty (50%) percent interest in Tenant
shall be deemed an assignment of the interest of Tenant in this Lease within the
meaning of this Article. Anything contained herein to the contrary
notwithstanding the provisions of this section H shall not apply to the sale
of shares by persons other than those deemed "insiders" within the meaning of
the Securities Exchange Act of 1934, as amended, where such sale is effected
through any recognized exchange or through the "over-the-counter market", unless
the same to be related to, result in or be the result of any merger,
consolidation, tender offer, takeover or other activity involving the
acquisition of control of Tenant by another unrelated corporation or legal
entity. All references to "Tenant" in this section H shall also


                                        8
<PAGE>   13
be deemed to refer to any immediate or remote subtenant or assignee of Tenant.

            Any assignment or subletting to a subsidiary or a division of
Manchester shall not be subject to the provisions of this paragraph in its
entirety, and shall not be deemed a violation of the lease provided that
Manchester remains liable under the lease.

            Any assignment of lease caused or created by a sale, merger,
consolidation, or transaction of a similar nature as to the whole of Manchester
and any division or subsidiary shall not be subject to the provisions of this
paragraph in its entirety and shall not be deemed in violation of the lease.

         I. In the event that Tenant fails to execute and deliver any assignment
or sublease to which Landlord consented under the provisions of this Article
within forty-five (45) days after the giving of such consent, then Tenant shall
again comply with all of the provisions of this Article before assigning its
interest in this lease or subletting the Demised Premises.

         J. The consent of Landlord to an assignment or a subletting shall not
relieve Tenant from obtaining the express consent in writing of Landlord to any
further assignment or subletting.

         K. If Tenant's interest in this Lease be assigned, or if the Demised
Premises or any part thereof be sublet or occupied by anyone other than Tenant,
Landlord may collect rent from the assignee, subtenant or occupant and apply the
net amount collected to the Fixed Annual Rent and all Additional Rent herein
reserved, but no such assignment, subletting, occupancy or collection shall be
deemed a waiver of the provisions of this Article or of any default hereunder or
the acceptance of the assignee, subtenant or occupant as Tenant, or a release of
Tenant from the further observance or performance by Tenant of all of the
covenants, conditions, terms and provisions on the part of Tenant to be
performed or observed.

         L. Tenant shall notify Bernstein Management Corp., or Landlord, of its
desire to assign this lease or sublet the premises. Upon the obtaining the
proposed assignee or sublessee, upon terms satisfactory to tenant, tenant shall
submit to landlord in writing (1) the name or the proposed assignee or
subtenant; (2) the terms and conditions of the proposed assignment or
subletting; (3) the nature or character of the business of the proposed assignee
or subtenant or any other information reasonably requested by landlord.

         M. If there is a dispute between Landlord and Tenant as to the
reasonableness of Landlord's refusal to consent to any subletting or assignment,
such dispute shall be determined by arbitration in The City of New York in
accordance with the prevailing rules of the American Arbitration Association.
The arbitrators shall be bound by the provisions of this Lease and shall not add
to, subtract from or otherwise modify such provisions. Notwithstanding any
contrary provisions hereof, Landlord shall not be liable to Tenant for a breach
of Landlord's covenant not unreasonably to withhold such consent and Tenant's
sole remedy in such event shall be to enter into the proposed subletting or
assignment.

 R16.

         In every case in which Tenant is required by the terms of this Lease to
pay to Landlord a sum of money (including, without limitation, payment of fixed
and additional rent) and payment is not made within ten (10) days after the same
shall become due, Tenant shall pay as additional rent hereunder, interest on
such sum or so much thereof as shall be unpaid from the date it becomes due
until it is paid. Such interest shall be computed at a rate which shall be two
(2%) percent per month; provided, however, in no event shall such interest be in
excess of the highest rate of interest which shall from time to time be
permitted under the laws of the State of New York to be charged on late payments
of sums of money due pursuant to the terms of a lease.

R17.

         Tenant agrees it shall indemnify and save Landlord harmless against all
costs, claims, loss or liability resulting from delay by Tenant in surrendering
the demised premises upon the expiration or earlier termination of this Lease,
including, without limitation, any claims made by any succeeding tenant founded
on such delay.


R18.

         If any law, decision, order, rule or regulation (collectively called
"Limiting Law") of any governmental authority shall have the effect of limiting
for any period of time the amount of Rent or other amounts payable by Tenant to
any amount less than the amount required by the Lease, then:

            a. Throughout the period of limitation, Tenant shall remain liable
            for the maximum amount of rent and other amounts which are legally
            payable; and

            b. When the period of limitation ends, or if the Limiting Law is
            repealed, or following any order or ruling that substantially
            restrains or prohibits enforcement of the Limiting Law, Tenant
            shall pay to Landlord, on demand (to the extent that payment of such
            amounts is not prohibited by law), all amounts that would have been
            due from Tenant to Landlord during the period of limitation but
            which were not paid because of the Limiting Law; and thereafter
            Tenant shall pay to Landlord rent and all other amounts due pursuant
            to this Lease, all calculated as though there had been no
            intervening period of limitation.


R19.

         Any default by Tenant under any other lease of space in the Building
shall be deemed a default of the same nature under this Lease.

R20.

         Tenant represents and warrants to Landlord that the only agent or
broker with whom Tenant has dealt in connection with this Lease and/or the
demised premises and/or the building containing the demised premises is
Bernstein Management Corp., and Aegis Realty Corp., and that this lease was not
brought about or procured through the use, negotiation and/or instrumentality of
any other agent or broker. Tenant covenants and agrees to indemnify and hold
Landlord harmless from and against any and all claims for commissions and other
compensation made by any other agent or agents and/or any other broker or
brokers based on any dealings between Tenant and any other agent or agents
and/or any other broker or brokers, together with all costs and expenses
incurred by Landlord in resisting such claims (including, without limitation
attorney's fees). Landlord agrees to pay any commission or fee due Bernstein
Management Corp., and Aegis Realty Corp., for bringing about this lease, and
Landlord represents that it knows of no claims by any other brokers.

R21.

         Tenant understands and agrees that changes in or to the demised
premises that require the hiring by Tenant of independent contractors or
subcontractors, either licensed or unlicensed, may only be made with the prior
written consent of the Landlord. Such consent not to be unreasonably withheld.

R22.

         Landlord may at any time request arbitration, and Tenant may at any
time when not in default in the payment of any rent request arbitration, of any
matter in dispute, but only where arbitration is expressly provided for in this
lease. The party requesting arbitration shall do so by giving notice to that
effect to the other party, specifying in said notice the nature of the dispute,
and said dispute shall be determined in New York City, by a single arbitrator,
in accordance with the rules then obtaining of the American Arbitration
Association (or any organization which is the successor thereto). The award in
such arbitration may be enforced on the application of either party by the order
of judgment of a court of competent jurisdiction. The fees and expenses of any
arbitration shall be borne by the parties equally, but each party shall bear the
expense of its own attorneys and experts and the additional expenses of
presenting its own proof. If tenant gives notice requesting arbitration as
provided above, Tenant shall simultaneously serve a duplicate of the notice on
each mortgagee and ground lessor whose name and address shall previously have
been furnished to Tenant, and such mortgagees and ground lessors shall have the
right to participate in such arbitration.

R23.

         In the event the Landlord herein is directed by any City, State or
Federal agency to comply with Local Law Legislation, due to Tenants use and
occupancy of the demised premises, which includes Local Laws 5, elevator
inspection, and Local Law 10, facade inspection, but not limited thereto, the
Tenant herein agrees to pay the cost to comply with said directives. These costs
will be deemed to be additional rent and will become due and payable on the
first day of the month succeeding the completion of the work, and will be paid
together with the rent. The Landlord reserves its right to collect said
additional rent in accordance with the terms provided in this lease.

R24.

         The square footage and percentage herein set forth in this lease are
approximate only and the Landlord and Tenant hereby agree that same shall not be
deemed a representation of Landlord. Landlord and Tenant hereby agree that the
square footage figure and percentage set forth has been determined solely for
the purpose of computing Tenant's contribution for escalation charges.

R25.

         If Tenant shall request Landlord's approval or consent and Landlord
shall fail or refuse to give such approval or consent, Tenant shall not be
entitled to any damages for any withholding or delay of such approval or consent
by Landlord, it being intended that Tenant's sole remedy shall be an action for
injunction or specific performance (the rights to money damages or other
remedies being hereby specifically waived), and that such remedy shall be
available only in those cases where Landlord shall have expressly agreed in
writing not to unreasonably withhold its consent or approval or where as a
matter of law Landlord may not unreasonably withhold its consent or approval.

R26.

         Landlord has installed and brought to the floor of the demised premises
a riser for AC electric current, and Tenant is hereby given the right to connect
to and draw AC current from said riser or to continue use of existing
connections to said riser and Tenant shall pay to Landlord as additional rent
hereunder, on the 1st day of each and every month


                                       11
<PAGE>   16

every month of the term, in advance, the sum of $ None for the right to use and
connect to said AC riser, Tenant shall not connect to nor make any additions or
changes to existing use of said risers without first obtaining Landlord's
written consent therefor, and tenant's connections to said riser and the use
thereof shall be subject to Landlord's rules and regulations for the building in
which the demised premises are located. The quantity of the AC current from said
AC riser allocated to Tenant, and which Tenant may use through its connections
thereto, shall be at the sole determination and discretion of Landlord; and
should Tenant use more AC current drawn from said riser than is allocated by
Landlord for the demised premises of which Landlord shall be the sole judge,
Tenant shall discontinue the excessive use of such current. It is understood
that Tenant shall pay for all electric current consumed by Tenant and including
that drawn from said AC riser.

R27.

         Tenant agrees that the value of the demised premises and the reputation
of the Owner will be seriously injured if the premises are used for any obscene
or pornographic purposes or any sort of commercial sex establishment. Tenant
agrees that Tenant will not bring or permit any obscene or pornographic material
on the premises, and shall not permit or conduct any obscene, nude, or semi-nude
live performances on the premises, nor permit use of the premises for nude
modeling, rap sessions, or as a so-called rubber goods Shops, or as a sex club

not permit any of these uses by any sublessee or assignee of the premises. This
Article shall directly bind any successors in interest to the Tenant. Tenant
agrees that if at any time Tenant violates any of the provisions of this
Article, such violation shall be deemed a breach of a substantial obligation of
the terms of this lease and objectionable conduct. Pornographic material is
defined for purposes of this Article as any written or pictorial matter with
prurient appeal or any objects of instrument that are primarily concerned with
lewd or prurient sexual activity. Obscene material is defined here as it is in
Penal Law Section 235.00.

R28.

         It is specifically understood and agreed that this lease is offered to
the Tenant for signature by the Managing Agent of the building solely in its
capacity as such Agent and subject to the Landlord's acceptance and approval and

the said lease shall not in any way bind the Landlord or its Agent until such
time as the Landlord has approved said lease and same is executed and delivered
to the Tenant.

R29.

         Notwithstanding any thing to the contrary contained in this Lease, any
monies due Landlord other that the annual rental are deemed to be additional
rent, and any default in the payment or additional rent shall give to Landlord
the same remedies as it has with respect to a default in the payment of rent.

R30.

         Landlord shall serve written notice to Tenant, giving Tenant 3 days
notice of Landlord's substantial completion of the work as described in R32 and
that Tenant may occupy the demised premises. Upon the expiration of said 3 day
notice, and for the six month period immediately following the expiration of
said 3 day notice, Tenant shall be allowed to occupy the demised premises base
rent free. Tenant shall be liable for all other charges during said period,
included but not limited to electric use.

R31.

         Simultaneously with the signing of this lease, the tenant will deliver
to landlord the amount of $23,437.50 in prepaid rent; said amount to be paid by

deleted in its entirety and the following paragraph is substituted in its place
and stead:

             "Bills shall be rendered at such times as Landlord may elect. In
             the event that such bills are not paid within ten (10) days after
             they are rendered and upon thirty (30) days written notice to cure
             directed to the Tenant, certified mail, return receipt, Landlord
             may, without further notice discontinue the service of electric

             upon forty-five (45) days notice to Tenant if Landlord so elects to

             electric service by the Landlord, Tenant shall not be released from
             any liability under this Lease, and Landlord shall not incur any
             liability for any loss or damage sustained by Tenant by such
             discontinuance. Such discontinuance shall not be deemed to be a
             lessening of services within the meaning of any law, rule, or
             regulation now or here after enacted, promulgated or issued. In the
             event of such discontinuance, Landlord shall permit Tenant to
             receive such service directly from said public utility corporation,
             in which event, the Tenant will, at its own cost and expense,
             furnish and install all risers, service wiring, and switches that
             may be necessary for such installation and required by the public
             utility company, and will, at its own cost and expense, maintain
             and keep in good repair all such risers, wiring and switches.
             Tenant shall make no alteration or additions to the electric
             equipment and/or appliances without the prior written consent of
             Landlord in each instance, which consent shall not be unreasonably
             withheld. Rigid

terms of this sub-paragraph:

             "Provided, however, that the liability of the Tenant, pursuant to
             the provisions of this paragraph, shall not exceed the sum of $500.
             for each year of the term of this lease."

         THIRD: As to R6.C - The terms and conditions of R6.C are herein deemed
deleted from the lease in their entirety and the following paragraph is

                               LEASE AGREEMENT
        THIS LEASE AGREEMENT, made and entered into by and between 
Crow-Childress-Donner, Limited, a Texas limited partnership____________________
("Landlord"), and Manchester Equipment Company, Inc., a New York corporation___
____________________________________________________________________("Tenant"):

                                 WITNESSETH:

        1.01  PREMISES. In consideration of the obligation of Tenant to pay
rent and of the other terms, provisions and covenants hereof, Landlord leases
to Tenant and Tenant leases from Landlord, all that portion of certain real
property situated within the County of Palm Beach, State of Florida, legally
described in Exhibit A, and the buildings and improvements to be constructed
thereon as outlined on the site plan contained in Exhibit B (the "Premises"),
including any truck loading areas specifically marked in red on said Exhibit B
for the exclusive use of Tenant. The Premises and the building within which the 
Premises are located (the "Building") are part of a larger development (the
"Development") commonly known as Congress Corporate Plaze, Phase II

        2.01  TERM OF LEASE. The term of this lease shall commence on the "Rent 
Commencement Date", as hereinafter defined, and ending 60 months thereafter,
provided however, that in the event the rent commencement date is a date other
than the first day of a calendar month, said term shall extend for said number
of months in addition to the remainder of the calendar month following the rent
commencement date.

        2.02  RENT COMMENCEMENT DATE. The "Rent Commencement Date" shall be the
date that Tenant first uses the Premises or any portion thereof for any purpose
permitted under this lease. In the event this lease pertains to a building or
building interior finish to be constructed, the "Rent Commencement Date" shall
be the date upon which the buildings and other improvements erected and to be
erected upon the premises shall have been substantially completed in accordance
with the plans and specifications described on Exhibit "C" attached hereto and
incorporated herein by reference, provided however, that if Landlord shall be
delayed in such substantial completion as a result of: (i) Tenant's failure to
agree to plans, specifications, and cost estimates, within a reasonable period
of time; (ii) Tenant's request for materials, finishes or installations other
than Landlord's standard; (iii) Tenant's changes in plans: the commencement
date and the payment of rent hereunder shall be accelerated by the number of
days of such delay, and provided further that if Landlord cannot substantially
complete the premises as a result of any events (i) through (iii) above,
Landlord may as its election complete so much of Landlord's work as may be
practical under the circumstances and, by written notice to Tenant, establish
the commencement date as the date of such partial completion, subject to any
applicable accelerations due to delays resulting from events (i) through (iii)
above. Taking possession by Tenant shall be deemed conclusively to establish
that said buildings and other improvements have been completed in accordance
with the plans and specifications and that the premises are in good and
satisfactory condition, as of when possession was so taken. Tenant acknowledges
that no representations as to the repair of the premises have been made by
Landlord, unless such are expressly set forth in the lease.  After such "Rent
Commencement Date" Tenant shall, upon demand, execute and deliver to Landlord a
letter of acceptance of delivery of the premises. In the event of any dispute
as to substantial completion of work performed, execute or required to be
performed by Landlord, the certificate of Landlord's architect or general
contractor shall be conclusive.

        3.01  BASE RENT Tenant agrees to pay to Landlord rent for the premises,
in advance, without demand, deduction or set off, for the entire term hereof at
the rate of Two thousand three hundred twenty one and 52/100------------Dollars
($2,321.52) per month. One such monthly installment shall be due and payable on
the date hereof and a like monthly installment shall be due and payable on or
before the first day of each calendar month succeeding the rent commencement
date, except that the rental payment for any fractional calendar month at the
commencement of the lease period shall be prorated. The rental payment is
subject to adjustment as provided below.

        3.02  RENT ESCALATION The base rent shall be subject to adjustment on
the first day of January of each year of the Lease term (such date being
hereafter referred to as the "rent adjustment date") in the following manner:
(a) Landlord and Tenant agree that on and as of the adjustment date each year
during the term of this lease, Landlord may increase the base rental for the
premises then due under the lease by a factor of 1.04 beginning January 1,
1991. Notwithstanding anything contained in this paragraph, the additional rent
payable by Tenant in any year pursuant to this paragraph shall in no event be
less than that paid in the prior year.

        4.01  SECURITY DEPOSIT. Tenant agrees to deposit with Landlord on the
date hereof the sum of Six thousand-----------------------------------Dollars
($6,000.00), which sum shall be held by Landlord, without obligation for
interest, as security for the full, timely and faithful performance of Tenant's
covenants and obligations under this Lease, it being expressly agreed that such
deposit is not an advance rental deposit or a measure of Landlord's damages.
Upon the occurrence of any event of default by Tenant, Landlord may, from
Landlord:_____________ Tenant:____________      
                                      1
<PAGE>   2
time to time, without prejudice to any other remedy, use such funds to the
extent necessary to make good any arrears of rent or other payments due Landlord
hereunder, and any other damage, injury, expense or liability caused by Tenant's
default; and Tenant shall pay to Landlord on demand the amount so applied in
order to restore the security deposit to its original amount. Although the
security deposit shall be deemed the property of Landlord, any remaining balance
of such deposit shall be returned by Landlord at such time after termination of
this Lease when Landlord shall have determined that all Tenant's obligations
under this Lease have been fulfilled.  

        5.01  PERMITTED USE. The Premises shall be continuously used for the
sole purpose of general business offices and/or for receiving, storing,
shipping and selling (other than the at retail) products, materials and
merchandise made and/or distributed by Tenant and for no other use or purpose.
Tenant shall at its own cost and expense obtain any and all licenses and permits
necessary for any such use. The overnight parking of automobiles, trucks or
other vehicles, and the outside storage of any property including trash or
garbage are prohibited. Tenant agrees that it shall, at its own cost and
expenses keep its employees, agents, customers, invitees, and/or licensees from
parking on any streets running through or contiguous to the buildings or
development of which the premises are part thereof. Tenant agrees that no
washing of any type will take place in the premises including the truck apron
and parking areas. Tenant shall not permit any objectionable or unpleasant
odors, smoke, dust, gas, noise or vibrations to emanate from the Premises, nor
take any other action which would constitute a nuisance or would disturb or
endanger any other tenants of Development or unreasonably interfere with such
tenants' use of their respective premises or permit any use which would
adversely affect the reputation of the Development. Tenant shall not receive,
store or otherwise handle any product, material or merchandise which is
explosive, highly flammable or constitutes a hazardous substance or waste.
Tenant shall not permit the Premises to be used for any purpose (including,
without limitation, the storage of merchandise) in any manner which would
render the insurance thereon void or increase the insurance rate thereof.
Tenant agrees to indemnify and hold Landlord harmless against any and all loss,
costs and claims, including attorney's fees relating to the improper storage,
handling, transportation or disposal of explosive, highly flammable or
hazardous materials or resulting from any other improper use. Tenants shall
comply with all governmental laws, ordinances and regulations applicable to the
Premises, and shall promptly comply with all governmental orders and directives
for the correction, prevention and abatement of any violations or nuisances in
or upon, or connected with, the Premises, all at Tenant's sole expense. If, as a
result of any change in the governmental laws, ordinances and regulations, the
Premises, all at Tenant's sole expense. If, as a result of any change in the
governmental laws, ordinances and regulations, the Premises must be altered to
accommodate lawfully the use and occupancy thereof, such alterations shall be
made only with the consent of Landlord, but the entire cost thereof shall be
borne by Tenant; provided that the necessity of Landlord's consent shall in no
way create any liability against Landlord for failure of Tenant to comply with
such laws, ordinances and regulations. Tenant shall take whatever other actions
are necessary so that the Premises and Tenant's use thereof complies with the
Fire Prevention Code of the National Fire Protection Association and any other
fire prevention laws, ordinances, rules or regulations applicable to the
Premises.

        6.01 TENANT'S TAXES. Tenant shall be responsible to pay before
delinquency all assessments, levies or charges measured by or base in whole or
in part upon the rents payable hereunder or the gross receipts of Tenant and
all sales taxes and other taxes imposed upon or assessed by reason of the rents
and other charges payable hereunder. The Florida sales tax imposed on rent and
on other charges payable hereunder shall be paid by Tenant to Landlord with the
payment of Tenant's rental payments and other charges payable hereunder.

        7.01 DEFINITION OF OPERATING COSTS. The term "Operating Costs" shall
mean all costs and expenses paid or incurred by Landlord or on Landlord;s
behalf in connection with the ownership, management, repair, replacement,
remodeling, maintenance and operation of the Development (including, without
limitation, all assessed real property taxes, assessments (whether general or
special) and governmental charges of any kind and nature whatsoever including
assessments due to deed restrictions and/or owner's associations, which accrue
against the building and/or development of which the premises are a part, the
costs of maintaining and repairing parking lots parking structures, easements,
and landscaping, property management fees, utility costs to the extent not
separately metered, insurance premiums, depreciation of the costs of
replacement (as defined below) of the building and improvements in the
Development but not including any structural repairs or replacements which are
normally chargeable to capital accounts under sound accounting principles, and
the Building's share of costs of the Development). The term "operating costs"
does not include: (i) costs of alterations of tenants' premises: (ii) costs of
curing construction defects; (iii) interest and principal payments on
mortgages, and other debt cost; (iv) real estate brokers' leasing commissions or
compensation; (v) any cost or expenditure for which Landlord is reimbursed,
whether by insurance proceeds or otherwise; (vi) cost of any service furnished
to any other occupant of the Building which Landlord does not provide to tenant
hereunder. Structural repairs and replacements are repairs and replacement to
the foundations, load-bearing walls, columns and joists and replacement of
roofing and roof deck. Notwithstanding anything contained herein to the
contrary, depreciation of any capital improvements which are intended to reduce
Operating Costs, or are required under any governmental laws, regulations or
ordinances, which were not applicable to the Building or the Development at the
time it was constructed, or are recommended by the N.F.P.A. Lifo Safety Code,
shall be included in Operating Costs. The useful life of any such improvement
as well as all non-structural replacements shall be reasonable determined by
Landlord. In addition, interest on the undepreciated cost of any such
improvement or non-structural replacement (at the prevailing construction loan
rate available to Landlord on the date the cost of such improvement was
incurred) shall also be including in Operating Costs. If Landlord selects the
accrual method of accounting rather than the cash accounting method for
Operating Costs purposes, Operating Costs shall be deemed to have been paid
when such expenses have accrued. Landlord shall have the right at any time and
from time to time to elect, which election shall be subject to revocation, to
exclude that portion of Operating Costs attributable to any separately assessed
part of the Development and any separate building within the Development.
During any period that Operating Costs attributable to any separately assessed
part of the Development and/or separate building are so excluded from Operating
Costs, then for the purposes calculating Tenant's proportionate share of
Operating Costs as provided in Section 7.02, the denominator shall not include
the rentable area of such separately assessed part of the Development and/or
such separate building. Landlord may, in a reasonable manner, allocate
insurance premiums for so-called "blanket" insurance policies which insure
other properties as well as the Development and said allocated amount shall be
deemed to be an Operating Cost.
        If at any time during the term of this lease, the present method of
taxation shall be changed so that in lieu of the whole or any part of any taxes,
assessments or governmental charges levied, assessed or imposed on real estate
and the improvements thereon, there shall be levied, assessed or imposed on
Landlord a capital levy or other tax directly on the rents received therefrom
and/or a franchise tax, assessment, levy or charge measured by or based, in
whole or in part, upon such rents for the present or any future building or
buildings on the premises, then all such taxes, assessments, levies or charges,
or the part thereof so measured or based, shall be deemed to be included within
the term "taxes" for the purposes hereof.

        7.02  TENANT'S PROPORTIONATE SHARE OF OPERATING COSTS.  Tenant shall
pay to Landlord, as additional rent, its proportionate share of operating costs
calculated on the basis of the ratio set forth in Section 8.01. Any payments
with respect to any partial calendar year in which the Term commences or ends
shall be prorated. Tenant agrees to pay $548.76 per month as an escrow amount
for operating costs as defined in Article 7.01. Landlord may, at any time,
deliver to Tenant its estimate (or revised estimate) of such additional amounts
payable under this Section for each calendar year. On or before the first day
of the next month and on or before the first day of each month thereafter.
Tenant shall pay to Landlord as additional rent such amount as Landlord
reasonably determines to be necessary to bring and keep Tenant current. As soon
as practicable after the close of each calendar

year, Landlord shall deliver to Tenant a statement showing the total amount
payable by Tenant under this Article. If such statement shows an amount due from
Tenant that is less than the estimated payments previously paid by Tenant, it
shall be accompanied by a refund of the excess to Tenant or at Landlord's
option the excess shall be credited against the next monthly installment of
rent. If such statement shows an amount due from Tenant that is more than the
estimated payments paid by Tenant, Tenant shall pay the deficiency to Landlord,
as additional rent. In the event an amount is due and is not paid within thirty
(30) days after the date of Landlord's statement to tenant, the unpaid amount
shall bear interest at the rate of eighteen (18%) percent per annum from the
date of such statement until payment by tenant. Landlord and Tenant acknowledge
that certain of the costs of management, operation and maintenance of the
Development are allocated among all of the buildings in the Development using
methods of allocation that are considered reasonable and appropriate under the
circumstances. Tenant hereby consents to such allocations provided that the
determination of such costs and the allocation of all or part thereof to
Operating Costs hereunder shall be in accordance with generally accepted
accounting principles applied on a consistent basis. Tenant or its
representatives shall have the right after seven (7) days prior written notice
to Landlord to examine Landlord's books and records of Operating Costs during
normal business hours within twenty (20) days following the furnishing of the
statement to Tenant. Unless Tenant takes written exception to any item within
thirty (30) days following the furnishing of the statement to Tenant (which
item shall be paid in any event), such statement shall be considered as final
and accepted by Tenant. The taking of exception to any item shall not excuse
Tenant from the obligation to make timely payment based upon the statement as
delivered by Landlord.

as used in this Lease with respect to the Building shall mean a fraction the

denominator of which shall be the rentable area contained in the Building, as
determined by Landlord. Tenant's "proportionate share" as used in this Lease
with respect to costs relating to more than the Building, shall mean a fraction
the numerator of which shall be the rentable area contained in the Premises and
the denominator of which shall be the rentable area of all buildings, as

contained in the Lease to the contrary, Landlord shall have the right, from
time to time, to add to or exclude from the Development real property and any
buildings constructed thereon. In the event Landlord elects to add to or

integrity and supports provided by any demising wall and shall, at its sole
cost and expense, properly repair any damage or injury to any demising wall
caused by Tenant or its employees, agents or invitees. Tenant shall, at its own
cost and expense, as additional rent, pay for the repair of any damage to the
Premises, the Building, or the Development resulting from and/or caused in
whole or in part by the negligence or misconduct of Tenant, its agents,
servants, employees, patrons, customers, or any other person entering upon the
Development as a result of Tenant's business activities or caused by Tenant's
default hereunder.


        (b) Tenant at its own cost and expense, enter into a regularly

maintenance of all paved areas including driveways and alleys, including, but
not limited to, cleaning, repaving, restripping and resealing. Tenant shall
immediately give Landlord written notice of any defect or need for repairs,
after which Landlord shall have a reasonable opportunity to repair the same or
cure such defect. Landlord's liability with respect to any defects, repairs or
maintenance for which Landlord is responsible under any of the provisions of
this Lease shall be limited to the cost of such repairs or maintenance or the
curing of such defect. The term "walls" as used herein shall not include
windows, glass or plate glass, doors, special store front or office entry.



        10.01  ALTERATIONS.  Tenant shall not make any alterations, additions
or improvements to the Premises (including, without limitation, the roof and

alterations, additions or improvements shall be made by Landlord for tenant's
account and Tenant shall fully reimburse Landlord for the entire cost thereof.
Tenant may, without the consent of Landlord, but at its own cost and expense
and in good workmanlike manner erect such shelves, bins, machinery and other
trade fixtures as it may deem advisable, without altering the basic character
of the Building or Development and without overloading the floor or damaging
such Building or Development, and in each case after complying with all
applicable governmental laws, ordinances, regulations and other requirements.
All shelves, bins, machinery and trade fixtures installed by Tenant may be
removed by Tenant prior to the termination of this Lease if Tenant so elects,
and shall be removed by the date of termination of this Lease or upon earlier
vacating of the Premises if required by Landlord; upon any such removal Tenant
shall restore the Premises to their original condition. All such removals and
restoration shall be accomplished in a good and workmanlike manner so as not to
damage the primary structure or structural quality of the Building.


        11.01   SIGNS AND WINDOW TREATMENT.  Tenant shall not install any signs
upon the Building or Development. Landlord will provide, at Tenant's request
and cost, Landlord's standard identification sign, which sign shall be removed
by Tenant upon termination of this Lease at which time Tenant shall restore the 
property to the same condition as prior to installation of said sign. Tenant
shall not install drapes, curtains, blinds or any window treatment without
Landlord's prior written consent. Landlord may from time to time require Tenant

<PAGE>   4
the cost of removing and replacing such signs. Landlord shall maintain all
signs and the cost thereof shall be charged to Tenant.

        12.01  INSPECTIONS.  Landlord and Landlord's agents and representatives
shall have the right to enter and inspect the premises at any reasonable time
during business hours, for the purpose of ascertaining the condition of the

least thirty (30) days prior to vacating the premises and shall arrange to meet
with Landlord for a joint inspection of the premises prior to vacating. In the
event of Tenant's failure to give such notice or arrange such joint inspection,
Landlord's inspection at or after Tenant's vacating the premises shall be
conclusively deemed correct for purposes of determining Tenant's responsibility
for repairs and restoration.

        13.01  UTILITIES.  Tenant shall pay for all gas, heat, light, power,
telephone, and other utilities and services used on or from the Premises,
including without limitation, Tenant's proportionate share as determined by

to assign, sublet, transfer or encumber this lease, or any interest therein,
without the prior written consent of Landlord which will not be unreasonably
withheld. Any attempted assignment, subletting, transfer or encumbrance by
Tenant in violation of the terms and covenants of this Paragraph shall be void.
All cash or other proceeds of any assignment, such proceeds as exceed the
rentals called for hereunder in the case of a subletting and all cash or other
proceeds of any other transfer of Tenant's interest in this lease shall be paid
to Landlord, whether such assignment, subletting or other transfer is consented
to by Landlord or not, unless Landlord agrees to the contrary in writing, and
Tenant hereby assigns all rights it might have or ever acquire in any such
proceeds to Landlord. Any assignment, subletting or other transfer of Tenant's
interest in this lease shall be for an amount equal to the then fair market
value of such interest. Those covenants shall run with the land and shall bind
Tenant and Tenant's heirs, executors, administrators, personal representatives,
representatives in any bankruptcy proceeding, successors and assigns. Any
assignee, sublessee or transferee of Tenant's interest in this lease (all such
assignees, sublessees and transferees being hereinafter referred to as
"successors"), by assuming Tenant's obligations hereunder shall assume
liability to Landlord for all amounts paid to persons other than Landlord by
such successors in contravention of this Paragraph. No assignment, subletting
or other transfer, whether consented to by Landlord or not, shall relieve
Tenant of its liability hereunder. Upon the occurrence of an "event of default"
as hereinafter defined, if the premises or any part thereof are then assigned or
sublet, Landlord, in addition to any other remedies herein provided, as
provided by law, may at its option collect directly from such assignee or
subtenant all rents becoming due to Tenant under such assignment or sublease
and apply such rent against any sums due to Landlord for Tenant hereunder, and
no such collection shall be construed to constitute a novation or a release of
Tenant from the further performance of Tenant's obligations hereunder.

        (b) If this lease is assigned to any person or entity pursuant to the
provisions of the Bankruptcy Code 11 U.S.C. 101 et seq., (The "Bankruptcy
Code"), any and all monies or other considerations payable or otherwise to be
delivered in connection with such assignment shall be paid or delivered to
Landlord, shall be and remain the exclusive property of Landlord and shall not
constitute property of Tenant or of the estate of Tenant within the meaning of
the Bankruptcy Code. Any and all monies or other considerations constituting
Landlord's property under the preceding sentence not paid or delivered to
Landlord shall be held in trust for the benefit of the Landlord and be promptly
paid or delivered to landlord.  

        (c) Any person or entity to which this lease is assigned pursuant to
the provisions of the Bankruptcy Code, shall be deemed, without further act or
deed, to have assumed all of the obligations arising under this lease on and
after the date of such assignment. Any such assignee shall upon demand
execute and deliver to Landlord an instrument confirming such assumption.*

        15.01  FIRE AND CASUALTY DAMAGE.  (a) Landlord agrees to maintain
insurance covering the building of which the premises are a part in an amount
not less than eighty (80%) percent (or such greater percentage as may be
necessary to comply with the provisions of any co-insurance clauses of the
policy) of the replacement cost thereof, insuring against the perils of Fire,
Lightning, Extended Coverage, Vandalism and Malicious Mischief, extended by
Special Extended Coverage Endorsement to insure against all other Risks of
Direct Physical Loss, such coverages and endorsements to be as defined,
provided and limited in the standard bureau forms prescribed by the insurance
regulatory authority for the state in which the premises are situated for use
by insurance companies admitted in such state for the writing of such insurance
on risks located within such state. Subject to the provisions of subparagraphs
15.01(c), 15.01(d), and 15.01(e) below, such insurance shall be for the sole
benefit of Landlord and under its sole control.


        (b) If the building situated upon the premises should be damaged or
destroyed by fire, tornado or other casualty, tenant shall give written notice
thereof to Landlord.

        (c) If the buildings situated upon the premises should be totally
destroyed by fire, tornado or other casualty, or if they should be so damaged
thereby that rebuilding or repairs cannot in Landlord's estimation be completed
within two hundred (200) days after the date upon which Landlord is notified by
Tenant of such damage, this lease shall terminate and the rent shall be abated
during the unexpired portion of this lease, effective upon the date of the
occurrence of such damage.*


        (d) If the buildings situated upon the premises should be damaged by
any peril covered by insurance to be provided by Landlord under subparagraph
15.01(a) above, but only to such extent that rebuilding or repairs can in
Landlord's estimation be completed within two hundred (200) days after the date
upon which Landlord is notified by Tenant of such damage, this lease shall not
terminate, and Landlord shall at its sole cost and expense thereupon proceed
with reasonable diligence to rebuild and repair such buildings to substantially
the condition in which they existed prior to such damage, except that Landlord
shall not be required to rebuild, repair or replace any part of the partitions,
fixtures, additions and other improvements which may have been placed in, on or
about the premises by Tenant and except that Tenant shall pay to Landlord upon
demand any amount by which Landlord's cost of such rebuilding, repair and/or
replacement exceeds net insurance proceeds paid to Landlord in connection with
such damage and except that Landlord may elect not to rebuild if such damage
occurs during the last year of the term of the lease exclusive of any option
which is unexercised at the time of such damage. If the premises are
untenantable in whole or in part following such damage, the rent payable
hereunder during the period in which they are untenantable shall be reduced to
such extent as may be fair and reasonable under all of the circumstances. In
the event that Landlord should fail to complete such repairs and rebuilding
within two hundred (200) days after the date upon which Landlord is notified by
Tenant of such damage. Tenant may at its option terminate this lease by
delivering written notice of termination to Landlord as Tenant's exclusive
remedy, whereupon all rights and or obligations hereunder shall cease and
terminate. Should construction be delayed because of changes, deletions, or
additions in construction requested by Tenant, strikes, lockouts, casualites,
acts of God, war, material or labor shortages, governmental regulation or
control or other causes beyond the reasonable control of Landlord, the period
of restoration, repair or rebuilding shall be extended for the time Landlord is
so delayed.*


        (e) Notwithstanding anything herein to the contrary, in the event the
holder of any indebtedness secured by a mortgage or deed of trust covering the
premises requires that the insurance proceeds be applied to such indebtedness,
then Landlord shall have the right to terminate this lease by delivering
written notice of termination to Tenant within fifteen (15) days after such 


Landlord: _____________ Tenant: _____________

* In the event that the premises are damaged or destroyed by fire, tornado or
  other casualty and cannot be repaired within 90 days, the Landlord agrees to
  provide temporary quarters to Manchester Equipment until the time when the
  original premises are ready to be occupied. In the event temporary quarters
  are provided the Tenant understands that the rent abatement described above
  will not apply.

requirement is made by any such holder, whereupon all rights and obligations
hereunder shall cease and terminate.

        (i) Each of Landlord and Tenant hereby releases the other from any loss
or damage to property caused by fire or any perils insured in policies of
insurance covering such property, even if such loss or damage shall have been
caused by the fault or negligence of the other party, or anyone for whom such
party may be responsible; provided, however, that this release shall be
applicable and in force and effect only with respect to loss or damage
occurring during such times as the releasor's policies shall contain a clause
or endorsement to the effect that any such release shall not adversely affect
or impair said policies or prejudice the right of the releasor to recover
thereunder and then only to the extent of the insurance proceeds payable under
such policies. Each of the Landlord and Tenant agrees that will request its
insurance carriers to include in its policies such a clause or endorsement.


        16.01  LIABILITY. Landlord shall not be liable to Tenant or Tenant's
employees, agents, patrons or visitors, or to any other person whomsoever, for
any injury to person or damage to property on or about the premises, resulting

its agents, servants or employees of any other person entering upon the
premises, or caused by the buildings and improvements located on the premises
becoming out of repair, or caused by leakage of gas, oil, water or steam or by
electricity emanating from the premises, or due to any cause whatsoever, and
Tenant hereby covenants and agrees that it will at all times indemnify and hold

employees from any loss, liability, claims, suits, costs, expenses, including
without limitation attorney's fees and damages, both real and alleged, arising

obligated to repair and maintain hereunder within a reasonable time after the
receipt of written notice from Tenant of needed repairs. Tenant shall procure
and maintain throughout the term of the lease a policy or policies of
insurance, at its sole cost and expense, insuring both Landlord and Tenant

companies satisfactory to Landlord. Certified copies of such policies, together

an event of default hereunder. The provision for such late charge shall be in
addition to all of Landlord's other rights and remedies hereunder or at law and
shall not be construed as liquidated damages or as limiting Landlord's remedies
in any manner.

        (d)  In the event Tenant's check, given to Landlord in payment, is
returned by the bank for non-payment, Tenant agrees to pay all expenses incurred
by Landlord as a result thereof.

        (e) Exercise by Landlord of any one or more remedies hereunder granted
or otherwise available shall not be deemed to be an acceptance of surrender of
the premises by Tenant, whether by agreement or by operation of law, it being
understood that such surrender can be effected only by the written agreement of
Landlord and Tenant. No such alteration of locks or other security devices and
no removal or other exercise of dominion by Landlord over the property of Tenant
or others at the premises shall be deemed unauthorized or constitute a
conversion, Tenant hereby consenting, after any event of default, to the
aforesaid exercise of dominion over Tenant's property within the premises. All
claims for damages by reason of such re-entry and/or repossession and/or
alteration of locks or other security devices are hereby waived, as are all
claims for damages by reason of any distress warrant, forcible detainer
proceedings, sequestration proceedings or other legal process. Tenant agrees
that any re-entry by Landlord may be pursuant to judgment obtained in forcible
detainer proceedings or other legal proceedings or without the necessity for any
legal proceedings, as the Landlord may elect, and Landlord shall not be liable
for trespass or otherwise.

        (f)  In the event Landlord elects to terminate the lease by reason of an
event of default, then notwithstanding such termination, Tenant shall be liable
for and shall pay to Landlord, at the address specified for notice to Landlord
herein, the sum of all rental and other indebtedness accrued to date of such
termination, plus, as damages, an amount equal to the greater of (i) the total
rental hereunder for the remaining portion of the lease term (had such term not
been terminated by Landlord prior to the date of expiration and (ii) the then
present value of the then fair rental value of the premises for such period.

        (g) In the event that Landlord elects to repossess the premises without
terminating the lease, or in the event Landlord elects to terminate the lease,
then Tenant at Landlord's option, shall be liable for and shall pay to Landlord,
at the address specified for notice to Landlord herein, all rental and other
indebtedness accrued to the date of such repossession, plus rental required to
be paid by Tenant to Landlord during the remainder of the  lease term until the
date of expiration of the term as stated in Section 3.01 diminished by any net
sums thereafter received by Landlord through reletting the premises during said
period (after deducting expenses incurred by Landlord as provided in
subparagraph 20.02(h). In no event shall Tenant be entitled to any excess of
any rental obtained by reletting over and above the rental herein reserved.
Actions to collect amounts due by Tenant to Landlord under this subparagraph may
be brought from time to time, on one or more occasions, without the necessity of
Landlord's waiting until expiration of the lease term. 


        (h) In case of any event of default or breach by Tenant, or threatened
or anticipatory breach or default, Tenant shall also be liable for and shall pay
to Landlord, at the address specified for notice to Landlord herein, in addition
to any sum provided to be paid above, brokers' fees incurred by Landlord in
connection with reletting the whole or any part of the premises; the costs of
removing and storing Tenant's or other occupant's property; the costs of
repairing, altering, remodeling or otherwise putting the premises into condition
acceptable to a new tenant or tenants, and all reasonable expenses incurred by
Landlord in enforcing or defending Landlord's rights and/or remedies including
reasonable attorney's fees. 

        (i) In the event of termination or repossession of the premises for an
event of default. Landlord shall not have any obligation to relet or to attempt
to relet the premises, or any portion thereof, or to collect rental after
reletting; and in the event of reletting, Landlord may relet the whole or any
portion of the premises for any period to any tenant and for any use and
purpose.

        (j) If Tenant should fail to make any payment or cure any default
hereunder within the time herein permitted, Landlord, without being under any
obligations to do so and without thereby waiving such default, may make such
payment and/or remedy such other default for the account of Tenant (and enter
the premises for such purpose), and thereupon Tenant shall be obligated to, and
hereby agrees, to pay Landlord upon demand, all costs, expenses and
disbursements (including reasonable attorney's fees) incurred by Landlord in
taking such remedial action.

        (k) In the event that Landlord shall have taken possession of the
premises pursuant to the authority herein granted then Landlord shall have the
right to keep in place and use all of the furniture, fixtures and equipment at
the premises, including that which is owned or leased to Tenant at all times
prior to any foreclosure thereon by Landlord or repossession thereof by any
lessor thereof or third party having a lien thereon, Landlord shall also have
the right to remove from the premises (without the necessity of obtaining a
distress warrant,writ of sequestration or other legal process) all or any
portion of such furniture, fixtures, equipment and other property located
thereon and to place same in storage at any premises within the County in which
the premises is located; and in such event. Tenant shall be liable to Landlord
for costs incurred by Landlord in connection with such remeoval and storage.
Landlord shall also have the right to relinquish possession of all or any
portion of such furniture, fixtures, equipment and other property to any person
("Claimant") claiming to be entitled to possession thereof who presents to
landlord a copy of any instrument represented to Landlord by Claimant to have
been executed by Tenant (or an predecessor Tenant) granting Claimant the right
under various circumstances to take possession of such furniture, fixtures,
equipment or other property, without the necessity on the part of Landlord to
inquire in to the authenticity of said instrument's copy of Tenant's or Tenant's
predecessor's signature(s) thereon and without the necessity of Landlord making
any nature of investigation or inquiry as to the validity of the factual or
legal basis upon which Claimant purports to act; and Tenant agrees to indemnify
and hold Landlord harmless from all cost, expense, loss, damage and liability
incident to Landlord's relinquishment of possession of all or any portion of
such furniture, fixtures, equipment or other property to Claimant. Any and all
property which may be removed from the Premises by Landlord pursuant to the
authority of this Lease or of Law, to which Tenant is or may be entitled, may be
handled, removed and stored, as the case may be, by or at the direction of
Landlord at the risk, cost and expense of Tenant, and Landlord shall in no event
be responsible for the value, preservation or safekeeping thereof. Tenant shall
pay to Landlord, upon demand any and all expenses incurred in such removal and
all storage charges against such property so long as the same shall be in
Landlord's possession or under Landlord's control. Any such property of Tenant
not retaken by Tenant from storage within thirty (30) days after the removal
from the Premises shall conclusively be presumed to have been conveyed by Tenant
to Landlord under this Lease as a bill of sale without further payment or credit
by Landlord to Tenant. The rights of Landlord herein stated shall be in addition

subordinate to any mortgage and/or deed of trust now or at any time hereafter
constituting a lien or charge upon the Development, the Building, or the
Premises, without the necessity of any act or execution of any additional
instrument of subordination; provided, however, that if the mortgagee, trustee,
or holder of any such mortgage or deed of trust elects to have Tenant's
interest in this Lease superior to any such instrument, then by notice to
Tenant from such mortgagee, trustee or holder, this Lease shall be deemed
superior to such lien, whether this Lease was executed before or after said
mortgage or deed of trust. Tenant shall at any time hereafter on demand execute
any instruments, releases or other documents which may be required by any
mortgagee for the purpose of evidencing the subjection and subordination of
this Lease to the lien of any such mortgage or for the purpose of evidencing

furnish materials or perform labor for any construction or repairs, and each
such claim shall affect and each such lien shall attach to, if at all, only the
leasehold interest granted to Tenant by this instrument. Tenant covenants and
agrees that it will pay or cause to be paid all sums legally due and payable by
it on account of any labor performed or materials furnished in connection with
any work performed on the premises on which any lien is or can be validly and
legally asserted against its leasehold interest in the premises or the
improvements thereon and that it will save and hold Landlord harmless from any
and all loss, cost or expense based on or arising out of asserted claims or
liens against the leasehold estate or against the right, title and interest of
the Landlord in the premises or under the terms of this lease. Tenant agrees to
give Landlord immediate written notice if any lien or encumbrance

Lease shall apply to, inure to the benefit of, and be binding upon, the parties
hereto and upon their respective heirs, legal representatives, successors and
permitted assigns, except as otherwise herein expressly provided. Landlord shall

assignment, become Landlord hereunder, thereby freeing and relieving the grantor

exceed the amount of rental then remaining unpaid for the then current Term
(exclusive of any renewal periods which have not then actually commenced). This
provision is not intended to be a measure or agreed amount of Landlord's
liability with respect to any particular breach and shall not be utilized by any
court or otherwise for the purpose of determining any liability of Landlord
hereunder, except only as a maximum amount not to be exceeded in any event. In
addition, it is expressly understood and agreed that nothing in this Lease shall
be construed as creating any liability against Landlord, or its successors and
assigns, personally, and in particular without limiting the generality of the
foregoing, there shall be no personal liability to pay any indebtedness accruing
hereunder or to perform any covenant, either express or implied, herein
contained, and that all personal liability of Landlord, or its successors and
assigns, of every sort, if any, is hereby expressly waived by Tenant, and that
so far as Landlord, or its successors and assigns is concerned Tenant shall look
solely to the Building for the payment thereof.
 
     (e) Except as set forth in Section 8.01 above, this Lease may not be
altered, changed or amended except by an instrument in writing signed by both
parties hereto.
 
     (f) All obligations of Tenant not fully performed as of the expiration or
earlier termination of the term of this Lease shall survive the expiration or
earlier termination of the Term, including without limitation, all payment
obligations with respect to Operating Costs and all obligations concerning the

Term, and prior to Tenant vacating the Premises, Landlord and Tenant shall
jointly inspect the Premises and Tenant shall pay to Landlord any amount
estimated by Landlord as necessary to put the Premises, including without
limitation heating and air conditioning systems and equipment therein, in good
condition and repair. Any work required to be done by Tenant prior to its

as estimated by Landlord, of Tenant's obligation hereunder for Operating Costs.

obligations of Tenant hereunder, with Tenant being liable for any additional
costs therefor upon demand by Landlord, or with any excess to be returned to
Tenant after all such obligations have been determined and satisfied, as the
case may be. Any security deposit held by Landlord shall be credited against the
amount payable by Tenant under this Section.
 
     (g) If any clause, provision or portion of this Lease or the application
thereof to any person or circumstance shall be invalid or unenforceable under
applicable law, such event shall not affect, impair or render invalid or
unenforceable the remainder of this Lease nor any other clause, phrase,
provision or portion hereof, nor shall it affect the application of any clause,
phrase, provision or portion hereof to other persons or circumstances, and it is
also the intention of the parties to this Lease that in lieu of each such
clause, phrase, provision or portion of this Lease that is invalid or
unenforceable, there be added as a part of this Lease a clause, phrase,
provision or portion as similar in terms to such invalid or unenforceable
clause, phrase, provision or portion as may be possible and be valid and
enforceable.
 
     (h) Submission of this Lease shall not be deemed to be a reservation of the
Premises. Landlord shall not be bound hereby until its delivery to Tenant of an
executed copy hereof signed by Landlord, already having been signed by Tenant,
and until such delivery Landlord reserves the right to exhibit and lease the
Premises to other prospective tenants. Notwithstanding anything contained herein
to the contrary Landlord may withhold delivery of possession of the Premises
from Tenant until such time as Tenant has paid to Landlord the security deposit
required hereunder and the first month's rent as required hereunder, and any
other sums required hereunder.
 
     (i) Tenant shall at any time and from time to time within ten (10) days
after written request from Landlord, execute and deliver to Landlord an estoppel
certificate, in form reasonable satisfactory to Landlord.

Landlord, Landlord shall not be liable or responsible for, and there shall be
excluded from the computations for any such time period, any delays due to
causes beyond the control of Landlord.
 
     (k) Radon is a naturally occurring radioactive gas that, when it has
accumulated in a building in sufficient quantities, may present health risks to
persons who are exposed to it over a time. Levels of radon that exceed federal
and state guidelines have been found in buildings in Florida. Additional
information regarding radon and radon testing may be obtained from your county
public health unit. The above statement is incorporated in the lease as a
requirement in order to comply with Florida Statute 404.056(8).

        RESTORING PREMISES TO ORIGINAL CONDITION: Lessee hereby accepts the
premises in the condition they are in at the beginning of this Lease and agrees
to maintain said premises in the same condition, order and repair as they are
at the commencement of said term, and to return at Lessee's expense the

cost and expense, maintain a heating/air-conditioning maintenance agreement with
a third party acceptable to Lessor. Lessee shall provide Lessor with a copy of
said agreement prior to occupancy of the premises. In the event Lessor pays
monies required to be paid by Lessee hereunder, Lessor shall demand repayment
of same from Lessee and Lessee shall make payment within ten (10) days of
receipt of said demand. Lessee's failure to make such repayment within the ten
day period shall constitute a default under the terms of this Lease. Lessor
warrants to Lessee that the air-conditioning and heating in the premises shall
be in good operating condition on the Commencement Date of this Lease.

        INSURANCE: Lessor shall insure the building, of which the premises are
a part, against damage by fire, including extended coverage, in any amount
Lessor in its sole discretion shall deem adequate, and shall maintain such
insurance throughout the term hereby demised. Lessee shall insure all of its
property in the premises against damage by fire, including extended coverage,

addition, Lessee shall also maintain with respect to the premises comprehensive
public liability insurance, with minimum limits of $1,000,000, $3,000,000 per

save harmless the Lessor from and against any loss, damage and liability
(except fire loss and losses covered by extended coverage endorsement insured
hereunder) occasioned by, growing out of or arising or resulting from any
default hereunder or any tortuous or negligent act on the part of the Lessee,
its agents, employees or general contractors.

        Lessee shall maintain the insurance coverage required herein with a
company or companies acceptable to the Lessor, insuring the Lessor and its
Managing Agent as additional named insureds as well as Lessee, against bodily
injury to or death of persons, and against property damage as herein provided.
Lessee shall deliver certificates of insurance indicating the above specified
coverage to the Lessor upon the commencement of the term of this Lease, and

policies shall be in a form reasonaly satisfactory to the Lessor and its
Managing Agent, and shall be placed with a company qualified to do business in
the jurisdiction in which the demised premises are located, and shall provide
that it (they) cannot be canceled without at least ten (10) days prior written
notice to the Lessor.

        WAIVER OF SUBROGATION: If either party hereto is paid any proceeds
under any policy of insurance naming such party as an insured on account of any
loss, damage or liability, then such party hereto releases the other party
hereto, to and only to the extent of the amount of such proceeds, from any and
all liability for such loss, damage or liability, notwithstanding that such
loss, damage or liability may arise out of negligent or intentially tortuous
act or omission of the other party, its

agents or employees, provided that such release shall be effective only with
respect to loss or damage occurring during such time as the appropriate policy
of insurance of the releasing party provides that such release shall not impair
the effectiveness of such policy or the insured's ability to recover 
thereunder. Each party hereto shall use reasonable efforts to have a clause to 
such effect included in its said policies, and shall promptly notify the other 
in writing if such clause cannot be included in any such policy.

        DESTRUCTION BY FIRE: If the premises shall be partially damaged by fire
or other casualty, the damages shall be repaired by the Lessor and until such
repairs are made the rent shall be apportioned according to the part of the
premises which is usable by the Lessee. Said repairs shall be made promptly
except that no penalty shall accrue for reasonable delay which may arise by
reason of adjustment of insurance on the part of the Lessor and/or Lessee and
for reasonable delay on account of labor problems or any other cause beyond the
Lessor's and/or Lessee's control. If the premises are totally damaged or
rendered wholly untenable by fire or other casualty, then Lessor shall have the 
option of terminating this Lease as of the date of such casualty within thirty
(30) days thereafter by giving written notice of the exercise of such option to
the Lessee and any rents or other payments shall be prorated as of the
effective date of such termination and proportionately refunded to Lessee or
paid to Lessor as the case may be.

        FIRE INSURANCE: The Lessee agrees to pay that portion of premiums for
insurance against loss by fire which are in excess of the minimum fire
insurance rating for the type of construction involved in the demised premises
provided that such excess is a direct result of Lessee's use and occupancy.
Lessee agrees that it shall have no interest in any amounts paid by any fire
insurance company to Lessor due to fire or other casualty loss.

        EMINENT DOMAIN: If the whole or any part of the premises hereby leased
shall be taken by any public authority under power of eminent domain then the
term of this Lease shall cease on the part so taken from the day the possession
of the part shall be acquired for any public purpose and the rent shall be paid
up to that day and if such portion of the demised premises is so taken as to
destroy the usefulness of the premises for the purpose for which the premises
were leased, then from that day the Lessee shall have the right to either
terminate this Lease or to continue in possession of the remainder of the same
under the terms herein provided, except that the rent shall be reduced in
proportion to the amount of the premises taken. The parties agree that the
Lessee shall not be entitled to any damages by reason of the taking of this
leasehold and shall have no claim against Lessor for the value of any unexpired
term of this Lease, leasehold improvements or goodwill.

        SUBORDINATION:  Lessee agrees that this Lease shall be, at Lessor's
option, either prior to or subject and subordinate to the lien of any mortgage
or deed of trust now or hereafter placed upon the premises, and to any
modifications, renewals or extensions thereof. Lessee further agrees to execute
subordination documents as reasonably required by Lessor's mortgagee from time
to time.

        DEFAULT:  Lessee shall be considered in default of this Lease upon the
happening of any one of the following:


        (A) Failure to pay the rent or any other sum required by the terms of
this Lease within fourteen (14) days after Lessee's receipt of written notice
from Lessor.

and the continuance therefore for thirty (30) days after written notice from
Lessor.

        (C) The commencement of any action or proceeding for the dissolution or
liquidation of Lessee, or for the appointment of a receiver or trustee of
Lessee's property, and the failure to discharge any such action within thirty
(30) days.

Lessee is declared bankrupt.

        (E) The abandonment of the premises by the Lessee.

        Upon default, as hereinabove defined, Lessor, with notice to Lessee,
may enter upon the premises without terminating the Lease and do any acts which
Lessor may deem necessary to cure such default, and Lessee agrees to pay Lessor
any damage and/or expense incurred thereby.

        Furthermore, upon default Lessor may, on ten (10) days advance written
notice to Lessee, terminate this Lease, and with legal process take possession
of the premises, and remove the Lessee or any other occupant. Lessor shall be
entitled to recover as damages from the Lessee an amount equal to the balance
of the rent, together with all legal and other expenses incurred including the
cost of reletting the premises. Lessee shall be credited, however, with any net
amounts received by the Lessor from the reletting of the premises. It is
expressly agreed that Lessor shall not be liable for any failure to relet the
premises. No act of the lessor shall be considered an acceptance of a surrender
of the premises, unless in writing. Lessor may maintain separate actions each
month to recover the damages, without waiting to the end of the term of the
rental of the premises.

suit, on account of claims of liens of laborers or materialmen or others for
work performed for, or materials or supplies furnished to, Lessee or persons

                                   PURPOSE


        Thompson Center was established to provide commercial enterprises
requiring office, showroom, warehouse, or light industrial space a desirable
home for their business. Since there will be many types and variations of
businesses included, it becomes necessary to provide rules and regulations so
all occupants will continue to enjoy this environment. It is this objective
that has led to the formulation of these rules for all businesses housed in
Thompson Center. These rules will be kept flexible and may be modified, if
necessary, for the overall benefit of park occupants.

        We hope you enjoy our park. If you ever have a problem of any type,
please contact Thompson-Rubin Associates and we will make every effort to
promptly resolve it.

general partners.

                             casualty or taking.

                             after written notice thereof; or
                        (b)  The LESSEE shall default in the observance or 
                             performance of any other of the LESSEE's covenants,
                             agreements, or obligations hereunder and such

                             days after written notice thereof; or
                        (c)  The LESSEE shall be declared bankrupt or insolvent
                             according to law, or, if any assignment shall be
                             made of LESSEE's property for the benefit of

                the observance or performance of any conditions or covenants on
                LESSEE's part to be observed or performed under or by virtue of

                without being under any obligation to do so and without thereby
                waiving such default, may remedy such default for the account
                and at the expense of the LESSEE. If the LESSOR makes any
                expenditures or incurs any obligations for the payment of money
                in connection therewith, including but not limited to,
                reasonable attorney's fees in instituting, prosecuting or
                defending any action or proceeding, such sums paid or
                obligations insured, with interest at the rate of 18 percent per
                annum and costs, shall be paid to the LESSOR by the LESSEE as
                additional rent.

                                PROMISSORY NOTE

$9,500,000.00                                          Date: Dec. 11, 1995

        For Value Received, MANCHESTER EQUIPMENT CO, INC., a New York
corporation (the "Borrower"), hereby promises to pay to the order of THE BANK OF
NEW YORK (the "Bank") at its 1100 Old Country Road, Plainview, New York 11803
office, the principal sum of Nine Million Five Hundred Thousand Dollars
($9,500,000.00) or the aggregate unpaid principal amount of all advances made by
the Bank to the Borrower (which aggregate unpaid principal amount shall be equal
to the amount duly endorsed and set forth opposite the date last appearing on
the sheet attached to this note), whichever is less.

        Advances hereunder shall bear interest at a rate per annum equal to: (1)
the "Alternate Base Rate" (as hereinafter defined), such rate to change on the
effective date of any change in the "Alternate Base Rate", or (2) such rate
(the "Note Rate") as shall be agreed to between the Bank and the Borrower at the
time of each advance, which Note Rate shall remain fixed until the Maturity Date
(as hereinafter defined) of such advance.

        As used herein "Alternate Base Rate" shall mean, for any day a rate per
annum equal to the higher of (i) the Prime Rate in effect on such day and (ii)
the Federal Funds Rate in effect on such day plus 1/2 of 1%. For purposes of
this definition: (A) "Prime Rate" shall mean the prime commercial lending rate
of the Bank as publicly announced to be in effect from time to time, such rate
to be adjusted automatically, without notice, on the effective date of any
change in such rate, and (B) "Federal Funds Rate" shall mean, for any day, the
weighted average of the rates on overnight Federal funds transactions with
members of the Federal Reserve System arranged by Federal funds brokers, as
published
<PAGE>   2
                                       2

for such day (or if such day is not a business day, for the next preceding
business day) by the Federal Reserve Bank of New York, or if such rate is not so
published for any day which is a business day, the average of quotations for
such day on such transactions received by the Bank from three Federal funds
brokers of recognized standing selected by the Bank. Any advance hereunder which
shall not be paid when due shall bear interest at a rate per annum equal to the
Alternate Base Rate plus two percent (2%), such rate to change on the effective
date of any change in the Alternate Base Rate.

        Advances hereunder which bear interest at the Alternate Base Rate shall
be payable on demand and may be prepaid in whole at any time or in part from
time to time. Advances hereunder which bear interest at the Note Rate shall be
payable on a maturity date (the "Maturity Date") as shall be agreed to between
the Bank and the Borrower at the time of each advance. The Borrower shall not
have the right to prepay any advance which bears interest at the Note Rate.

        Interest shall be computed on the basis of a 360 day year for the actual
number of days involved. Interest on any advance shall be payable on the last
business day of the month, and at maturity.

        The Bank shall endorse the Note Rate and the Maturity Date applicable to
each advance which bears interest at the Note Rate on the sheet attached to this
note. The Bank shall charge the Borrower's deposit account maintained at the
Bank for each payment of principal and interest due hereunder on the due date
thereof. If the Bank shall make a new advance on a day on which the Borrower is
to repay an advance hereunder, the Bank shall apply the proceeds of the new
advance to make such repayment and only the amount by which the amount being
advanced exceeds the amount being repaid shall be made available to the Borrower

the Borrower to make an advance or receive a repayment hereunder and to endorse
the sheet attached to this note accordingly. All advances made hereunder shall
be credited to the Borrower's deposit account referred to above, which credits
shall be confirmed to the Borrower by standard advice of credit. The Borrower
agrees that the actual crediting of the sum of money so borrowed to the
Borrower's deposit account shall constitute conclusive evidence that the advance
was made, and the failure of the Bank to endorse the amount of any advance on
the sheet attached to this note or to forward to the Borrower an advice of
credit shall not affect the obligation of the Borrower to repay such advance.

        All advances made hereunder are secured pursuant to the terms of a
General Loan and Security Agreement executed by the Borrower in favor of the
Bank and this note is entitled to all the benefits thereof.

        All advances made hereunder shall become immediately due and payable,
together with all accrued interest, upon the insolvency, general assignment,
receivership, bankruptcy or dissolution of the Borrower. The Borrower does
hereby forever waive presentment, demand, protest, notice of protest and notice
of nonpayment or dishonor of this note.

        The Borrower hereby agrees to pay all reasonable expenses incurred by
the Bank incidental to or in any way relating to the Bank's enforcement of the
obligations of the Borrower hereunder, including but not limited to, reasonable
attorney's fees incurred by the Bank.

        The Borrower waives the right to trial by jury in any action, proceeding
or counterclaim instituted with respect to this note.

rights and obligations hereunder determined in accordance with the laws of the
State of New York.

                      GENERAL LOAN AND SECURITY AGREEMENT

Plainview,          New York                                     Dec. 2, 1993
- -------------------
(Banking Office)

        FOR VALUE RECEIVED, and in order to induce THE BANK OF NEW YORK
(hereinafter referred to as the "Bank"), in its discretion, to make loans or
otherwise extend credit at any time, and from time to time to, or at the
request of, the undersigned (hereinafter referred to as "Borrower"), whether
the loans or credit so extended shall be absolute or contingent. Borrower,
jointly and severally, if more than one, hereby grants to the Bank, as security
for all present or future obligations or liabilities of any and all kinds of
Borrower to it, whether incurred by Borrower as maker, endorser, drawer,
acceptor, guarantor, accommodation party or otherwise, matured or unmatured,
secured or unsecured, absolute or contingent, joint or several, and howsoever
or whensoever acquired by the Bank (all of which are hereinafter referred to as
the "Obligations"), a security interest in and a lien upon all personal
property and fixtures of Borrower now or hereafter existing or acquired and
wherever located which are of the type which may be collateral under the
Uniform Commercial Code as in effect in the State of New York (hereinafter
referred to as the "Code") on the date hereof, now or hereafter owned or
acquired by Borrower, or in which Borrower may have an interest, including all
goods (other than household goods as such term is defined in 12 CFR Part 227
unless the proceeds of the Obligation secured pursuant hereto are used to
purchase such goods or such Obligation is incurred for a business purpose or to
purchase real property), money, instruments, accounts, contract rights,
documents, chattel paper and general intangibles of Borrower, including but not
limited to any property specified in Schedule A hereto and also including all
products and proceeds of, all accessions to, and substitutions for, all of the
foregoing (all of which shall be hereinafter collectively referred to as the
 "Collateral").

        Borrower hereby agrees to deliver to the Bank whenever called for by it
such additional collateral security of a kind and of a market value
satisfactory to the Bank, so that there will, at all times, be with the Bank a
margin of security for the payment of all Obligations which shall be
satisfactory to it. In addition to the Bank's security interest in the
Collateral, it shall have, and Borrower hereby grants to the Bank, a security
interest and a lien for all the Obligations in and upon any personal property
of Borrower or in which Borrower may have an interest which is now or may at
any time hereafter come into the possession or control of the Bank, or of any
third party acting on its behalf, whether for the express purpose of being used
by the Bank as collateral security or for safekeeping or for any other or
different purpose, including such personal property as may be in transit by
mail or carrier for any purpose, or covered or affected by any documents in the
Bank's possession or control, or in the possession or control of any third
party acting on its behalf. Borrower hereby authorizes the Bank in its
discretion, at any time, whether or not the Collateral is deemed by it
adequate, to appropriate and apply upon any of the Obligations, whether or not
due, any of such property of Borrower and to charge any of the Obligations
against any balance of any account standing to the credit of Borrower on the
books of the Bank (said additional personal property is also hereinafter
referred to as the "Collateral").

        If any of the following events shall occur with respect to any Obligor
(which term shall include Borrower and any endorser or guarantor of any of the
Obligations): (1) the failure of Borrower to furnish satisfactory additional
Collateral upon demand; (2) the failure of any Obligor in the performance of
any of such Obligor's covenants herein or in any instrument, document or
agreement delivered in connection with any Obligation; (3) the death of the
insured under any life insurance policy held as Collateral, or the non-payment
of any premiums on any such life insurance policy; (4) default by any Obligor
with respect to the payment of any Obligation; (5) the insolvency, general
assignment, receivership, bankruptcy, or dissolution of any Obligor or the
filing of any petition by or against any Obligor with respect to any of the
foregoing; (6) the death, dissolution or incompetence of any Obligor; (7) the
financial condition or credit standing of any Obligor shall be or become
materially impaired in the sole opinion of the Bank or any of its officers; (8)
non-payment when due of any other liability of any Obligor; (9) the
commencement of any proceeding, procedure or other remedy supplemental to the
enforcement of a judgment against any Obligor; (10) any representation in any
financial or other statement of any Obligor delivered to the Bank by or on
behalf of any Obligor is untrue or incomplete; or (11) any Obligor shall fail,
on request, to furnish any financial information or to permit inspection of
such Obligor's books and records; then all Obligations shall become due and
payable forthwith, upon declaration to that effect by the Bank, without notice
to Borrower or any other Obligor, anything contained herein or in any other
document, instrument or agreement to the contrary notwithstanding.

        Upon failure of Borrower to pay any Obligation when becoming or made
due, as aforesaid, the Bank shall have, in addition to all other rights and
remedies allowed by law, the rights and remedies of a secured party under the
Code as in effect at that time and, without limiting the generality of the
foregoing, the Bank may immediately, without demand of performance and without
notice of intention to sell or of time or place of sale or of redemption or
other notice or demand whatsoever to Borrower, all of which are hereby
expressly waived, and without advertisement (a) sell at public or private sale,
grant options to purchase or otherwise realize upon, in the State of New York,
or elsewhere, the whole or from time to time any part of the Collateral upon
which the Bank shall have a security interest or lien as aforesaid, or any
interest which Borrower may have therein, and (b) exercise any and all rights,
options, powers, benefits or privileges given to the Bank upon the life
insurance policies, if any, held as Collateral. After deducting from the
proceeds of any such sale or other disposition of the Collateral all expenses
(including all reasonable expenses for legal services of every kind and other
expenses as set forth below), the Bank shall apply the residue of such proceeds
toward the payment of any of the Obligations, in such order as the Bank shall
elect, Borrower remaining liable for any deficiency, plus interest thereon,
remaining unpaid after such application. If notice of any sale or other
disposition is required by law to be given, Borrower hereby agrees that a
notice sent at least two days before the time of any intended public sale or of
the time after which any private sale or other disposition of the Collateral is
to be made, shall be reasonable notice of such sale or other disposition.
Borrower also agrees to assemble the Collateral at such place or places as the
Bank designates by written notice.

        At any such sale or other disposition the Bank or any other person
designated by the Bank may itself purchase the whole or any part of the
Collateral sold, free from any right of redemption on the part of Borrower,
which right is hereby waived and released.

        The Bank may, without any notice to Borrower, in its discretion,
whether or not any of the Obligations be due, in its name or in the name of
Borrower, demand, sue for, collect and receive any money or property at any
time due, payable or receivable on or on account of or in exchange for, and may
compromise, settle or extend the time of payment of, any of the demands or
obligations represented by any of the Collateral, and may also exchange any of
the Collateral for other property upon the reorganization, recapitalization or
other readjustment of the issuer, maker or other person who is obligated on or
otherwise has liabilities with respect to the Collateral, and in connection
therewith, may deposit any of the Collateral with any committee or depositary
upon such terms as the Bank may in its discretion deem appropriate, and
Borrower does hereby constitute and appoint the Bank Borrower's true and lawful
attorney to compromise, settle or extend payment of said demands or
obligations and exchange such Collateral as Borrower might or could do
personally; all without liability or responsibility for action herein
authorized and taken or not taken in good faith. The Bank is entitled at any
time in its discretion to notify an account debtor or the obligor on any
instrument to make payment to it, regardless of whether or not Borrower had
been previously making collections on the Collateral, and the Bank may take
control of any proceeds of any of the Collateral.

        Borrower agrees that the Collateral secures, and further agrees to pay
on demand, all expenses (including reasonable expenses for legal services of
every kind and cost of any insurance and payment of taxes or other charges) of
or incidental to, the custody, care, sale or collection of, or realization
upon, any of the Collateral or in any way relating to the enforcement or
protection of the rights of the Bank hereunder.

        Borrower agrees to mark its books and records as the Bank shall request
in order to reflect the rights of the Bank granted herein, and the Bank may, in
its sole discretion, take possession of the Collateral at any time, either
prior to or subsequent to a default under any of the Obligations. Borrower
agrees to maintain such insurance on the Collateral as the Bank may require.
The Bank may, without any notice to Borrower, in its discretion, and for its
own benefit, lend, use, transfer or repledge with any person, firm or
corporation all or any part of the Collateral by itself or mingled with the
property of others, in bulk or otherwise. The Bank may, without any notice to
Borrower, sell, assign or transfer any of the Obligations and the Bank's rights
and duties hereunder, and may deliver the Collateral, or any part thereof, to
the assignee or transferee of any of the Obligations, who shall become vested
with all the rights, remedies, powers, security interests and liens herein
given to the Bank in respect thereto; and the Bank shall thereafter be relieved
and fully discharged from any liability or responsibility in the premises.

  
<PAGE>   2
        The Bank may, without any notice to Borrower, in its discretion,
transfer, or cause to be transferred, all or any part of the Collateral to its
name, or to the name of its nominee, vote the Collateral so transferred, and
receive income and make or receive collections, including money, thereon and
hold said income and collections as Collateral or apply the said income and
collections to any of the Obligations, the manner and distribution of the
application to be made as the Bank shall elect.
        Calls for Collateral, demand for payment or notice to Borrower may be
given by leaving same at the address given below or any other address hereafter
filed with the Bank, or by mailing same to such address with the same effect as
if delivered personally. Such notice given in the manner herein provided shall
be effective whether or not received by Borrower. Borrower agrees not to change
any of its places of business, remove any records of Borrower relating to any
of the Collateral or move any of the Collateral without giving the Bank thirty
days' prior written notice.
        With respect to the Collateral, the Bank shall be under no duty to send
notices, perform services, exercise any rights of collection, enforcement,
conversion or exchange, vote, pay for insurance, taxes or other charges or take
any action of any kind in connection with the management thereof and its only
duty with respect thereto shall be to use reasonable care in its custody and
preservation while in its possession, which shall not include any steps
necessary to preserve rights against prior parties.
        Borrower hereby authorizes the Bank at Borrower's expense to file one
or more financing statements to perfect the security interests granted herein
without Borrower's signature thereon, and Borrower agrees to do, file, record,
make, execute and deliver all such acts, deeds, things, notices, instruments,
and financing statements as the Bank may request in order to perfect and
enforce the rights of the Bank herein.
        If at any time it is necessary in the opinion of counsel to the Bank
that any or all of the securities held as Collateral (the "Pledged Securities")
be registered under the Securities Act of 1933, as amended, or that an
indenture with respect thereto be qualified under the Trust Indenture Act of
1939 in order to permit the sale or other disposition of the Pledged
Securities. Borrower shall at the Bank's request and at the expense of Borrower
use the best efforts of Borrower promptly to cause the registration of the
Pledged Securities and the qualification of such indenture and to continue such
registration and qualification as long as deemed appropriate by the Bank.
        Borrower hereby authorizes the Bank to date this agreement as of the
date of the granting of any Obligation secured hereby and to complete any blank
space herein (including any blank space in Schedule A) according to the terms
upon which said Obligation was granted.
        No failure on the part of the Bank to exercise, and no delay in
exercising, any right, remedy or power hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise by the Bank of any right,
remedy or power hereunder preclude any other or future exercise of any other
right, remedy or power.
        Each and every right, remedy and power hereby granted to the Bank or
allowed it by law or other agreement shall be cumulative and not exclusive of
any other, and may be exercised by the Bank from time to time.
        Borrower and each endorser or guarantor of any of the Obligations
expressly waives presentment and demand for payment, protest and notice of
protest and of non-payment. Unless the text otherwise requires, all terms used
herein shall have the meanings specified in the Code.
        THE BANK AND BORROWER HEREBY WAIVE AND AGREE TO WAIVE THE RIGHT TO
TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM INSTITUTED WITH RESPECT
TO ANY MATTER WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS
AGREEMENT. 
        The provisions of this agreement shall be construed and interpreted and
all rights and duties hereunder determined in accordance with the laws of the
State of New York.
        Every provision of this agreement is intended to be severable: if any
term or provision of this agreement shall be invalid, illegal or unenforceable
for any reason whatsoever, the validity, legality and enforceability of the
remaining provisions hereof shall not in any way be affected or impaired
thereby. 

This agreement restates and amends in its entirety, without a break in
continuity, that certain Security Agreement dated December 12, 1988 between
Manchester Equipment Co., Inc. and Barclays Bank of New York, to whose rights,
the Bank has succeeded.

                          (Individual or Partnership)


                                                                December 1, 1993


        FOR VALUE RECEIVED, and in consideration of loans made or to be made or
credit otherwise extended or to be extended by THE BANK OF NEW YORK
(hereinafter referred to as the "Bank") to or for the account of Manchester
Equipment Co., Inc. of 50 Marcus Blvd., Hauppauge, New York 11788 (hereinafter
referred to as the "Borrower") from time to time and at any time and for other
good and valuable consideration and to induce the Bank, in its discretion, to
make such loans or extensions of credit and to make or grant such renewals,
extensions, releases of collateral or relinquishments of legal rights as the
Bank may deem advisable, the undersigned (jointly and severally, if more than
one guarantor, absolutely and unconditionally guarantee to the Bank, its
successors, endorsees and assigns, the prompt payment when due of all present
and future obligations and liabilities of any and all kinds of the Borrower to
the Bank and of all instruments of any nature evidencing or relating to any
such obligations and liabilities upon which the Borrower or one or more parties
and the Borrower is or may become liable to the Bank, whether incurred by the
Borrower as maker, endorser, drawer, acceptor, guarantor, accommodation party
or otherwise, and whether due or to become due, secured or unsecured, absolute
or contingent, joint or several, and howsoever or whenever acquired by the Bank
(all of which are herein collectively referred to as the "Obligations"), and
irrespective of the genuineness, validity, regularity or enforceability of such
Obligations, or of any instrument evidencing any of the Obligations or of any
collateral therefor or of the existence or extent of such collateral.

        The undersigned hereby assents that the Bank may at any time and from
time to time, either before or after the maturity thereof, without notice to or
further consent of the undersigned, extend the time of payment of, exchange,
release, substitute or surrender any collateral for, renew or extend any of the
Obligations or increase the interest rate thereon, and may also make any
agreement with the Borrower or with any other party to or person liable on any
of the Obligations, or interested therein, for the extension, renewal, payment,
compromise, discharge or release thereof, in whole or in part, or for any
modification of the terms thereof or of any agreement between the Bank and the
Borrower or any such other party or person, without in any way impairing or
affecting this guarantee.

        The undersigned hereby agrees that this guarantee shall not be impaired
or otherwise affected by any failure to call for, take, hold, protect or
perfect, continue the perfection of or enforce any security interest in or
other lien upon, any collateral for the Obligations, or by failure to exercise,
delay in the exercising or waiver of, or forbearance with respect to, any
right or remedy available to the Bank with respect to the Obligations.

        The undersigned hereby acknowledges that the undersigned has derived or
expects to derive a financial or other advantage from each and every Obligation
incurred by the Borrower to the Bank.

        The undersigned waives notice of the acceptance of this guarantee and
of the making of any such loans or extensions of credit or the incurrence of
any Obligation, presentment to or demand of payment from anyone whomsoever
liable upon any of the Obligations, protest, notice of presentment, non-payment
or protest and notice of any sale of collateral security or any default of any 
sort.

        To secure the liabilities of the undersigned under this guarantee, the
undersigned hereby grants to the Bank a security interest in and a lien upon
any personal property of the undersigned or in which the undersigned may have
an interest which is now or may at any time hereafter come into the possession
or control of the Bank, or of any third party acting in its behalf, whether for
the express purpose of being used by the Bank as collateral security or for
safekeeping or for any other or different purpose including such personal
property as may be in transit by mail or carrier for any purpose or covered or
affected by any documents in the Bank's possession or control, or in the
possession or control of any third party acting in its behalf. The undersigned
hereby authorizes the Bank in its discretion, at any time, to appropriate and
apply upon any of the liabilities of the undersigned under this guarantee any
such property of the undersigned and to charge any of such liabilities against
any balance of any account standing to the credit of the undersigned on the
books of the Bank. To satisfy the liabilities of the undersigned under this
guarantee, the Bank shall have, in addition to all other rights and remedies
allowed by law, the rights and remedies of a secured party under the Uniform
Commercial Code as in effect in the State of New York at the date hereof and,
without limiting the generality of the foregoing, the Bank may immediately,
without demand of performance and without notice of intention to sell or of
time or place of sale or of redemption or other notice or demand whatsoever to
the undersigned, all of which are hereby expressly waived, and without
advertisement, sell at public or private sale, grant options to purchase or
otherwise realize upon, in the State of New York, or elsewhere, the whole or
from time to time any part of the said collateral upon which the Bank shall
have a security interest and lien as aforesaid, and after deducting from the
proceeds of sale or other disposition of the said collateral all expenses
(including all reasonable expenses for legal services of every kind and other
expenses as set forth below) shall apply the residue of such proceeds toward
the payment of any of the liabilities of the undersigned under this guarantee
in such order as the Bank shall elect, the undersigned remaining liable for any
deficiency remaining unpaid after such application. If notice of any sale or
other disposition is required by law to be given, the undersigned hereby agrees
that a notice sent at least two days before the time of any intended public
sale or of the time after which any private sale or other disposition of the
said collateral is to be made, shall be reasonable notice of such sale or 
other disposition.

        At any such sale or other disposition the Bank may itself purchase the
whole or any part of the collateral sold, free from any right of redemption on
the part of the undersigned, which right is hereby waived and released.

        The undersigned agrees that the aforementioned collateral secures, and
further agrees to pay on demand, all expenses (including reasonable expenses
for legal services of every kind and cost of any insurance and payment of taxes
or other charges) of, or incidental to, the custody, care, sale or collection
of, or realization upon, any of the said collateral or in any way relating to
the enforcement or protection of the rights of the Bank hereunder or with
respect to any of the Obligations.

        This is a continuing guarantee and shall remain in full force and effect
and be binding upon the undersigned, and the undersigned's personal
representatives and assigns, until written notice of its revocation shall
actually be received by the Bank at the office of the Bank at which the
Borrower's account is maintained. No such revocation shall release the
undersigned or effect in any manner the rights, remedies, powers, security
interests and liens of the Bank under this guarantee with respect to any of the
Obligations arising prior to actual receipt by the Bank of such written notice
of revocation and any renewals or extensions thereof and any such revocation by
one of the undersigned shall not affect the continuing liabilities hereunder of
such of the undersigned as do not give such notice of revocation. If any of the
present or future Obligations are guaranteed by persons, partnerships or
corporations in addition to the undersigned, the death, release or discharge in
whole or in part, or the bankruptcy, liquidation or dissolution of one or more
of them, shall not discharge or affect the liabilities of the undersigned under
this guarantee.

        This guarantee shall continue to be effective or be reinstated, as the
case may be, if at any time payment of all or any part of any of the
Obligations is rescinded or must be restored or returned by the Bank whether
under any reorganization, bankruptcy or insolvency proceeding or otherwise.


 
<PAGE>   2
        This guarantee is a guarantee of payment and not of collection, and the
Bank shall be under no obligation to take any action against the Borrower or
any other person liable with respect to any of the Obligations or resort to any
collateral security held by it to secure any of the Obligations as a condition
precedent to the undersigned being obligated to perform as agreed herein. The
undersigned hereby waives any rights to interpose any defense, counterclaim or
offset of any nature and description which it may have or which may exist
between and among the Bank, the Borrower and/or the undersigned.
                            (SEE REVERSE SIDE)
<PAGE>   3
        The undersigned hereby waives any rights to be subrogated to the rights
of the Bank with respect to the Obligations and the undersigned waives any
right to and agrees that it will not institute or take any action against the
Borrower seeking contribution, reimbursement or indemnification by the
Borrower with respect to any payments made by the undersigned to the Bank
hereunder. 

        No failure on the part of the Bank to exercise, and no delay in
exercising, any right, remedy or power hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise by the Bank of any right,
remedy or power hereunder preclude any other or future exercise thereof or
the exercise of any other right, remedy or power.

        Each and every right, remedy and power hereby granted to the Bank or
allowed it by law or other agreement shall be cumulative and not exclusive of
any other, and may be exercised by the Bank at any time and from time to time.

        This guarantee embodies the entire agreement among the Bank and the
undersigned with respect to the subject matter hereof and supersedes all prior
agreements and understandings relating to the subject matter hereof.

        The undersigned and the Bank waive the right to trial by jury in any
action or proceeding based upon, arising out of or in any way connected to this
guarantee or any of the transactions contemplated hereby.

        This guarantee shall be construed and interpreted in accordance with the
laws of the State of New York. Unless the text otherwise requires, all terms
used herein shall have the meanings specified in the Uniform Commercial Code as
in effect in the State of New York at the date hereof. The undersigned submits
to the jurisdiction of state and federal courts located in the City and State of
New York in personam and agrees that all actions and proceedings relating
directly or indirectly to this guarantee shall be litigated only in said courts
or courts located elsewhere as the Bank may select and that such courts are
convenient forums. The undersigned waives personal service upon it and consents
to service of precess out of said courts by mailing a copy thereof to it by
registered or certified mail.

        Nothing except cash payment in full of the Obligations shall release
the undersigned or any of them from liability under this guarantee.

        If the undersigned is a partnership, the undersigned represents and
warrants that the general partners of the partnership executing this guarantee
are authorized and directed so to do on behalf of the undersigned and that the
execution and delivery of this guarantee does not conflict with the terms of
the undersigned's partnership agreement and all necessary and proper
partnership action has been taken to execute and deliver this guarantee and all
of the provisions hereof are legal, binding and valid obligations of the
undersigned, enforceable against the undersigned in accordance with its terms.


        IN WITNESS THEREOF, this guarantee has been executed by the undersigned
on this 1st day of DECEMBER, 1993.

                                                                 Exhibit 10.7.b

                       AGREEMENT FOR WHOLESALE FINANCING
                       (SECURITY AGREEMENT - ARBITRATION)

This Agreement for Wholesale Financing ("Agreement") is made as of 11-19, 1993
between ITT Commercial Finance Corp. ("ITT") and Manchester Equipment Co.,
Inc., a / / SOLE PROPRIETORSHIP, / / PARTNERSHIP, /X/ CORPORATION (check
applicable term) ("Dealer"), having a principal place of business located at 
50 Marcus Blvd., Hauppauge, NY 11788.

1. Subject to the terms of this Agreement, ITT, in its sole discretion, may
extend credit to Dealer from time to time to purchase inventory from ITT
approved vendors. ITT may combine all of ITT's advances to Dealer or on Dealer's
behalf, whether under this Agreement or any other agreement, to make one debt
owed by Dealer. ITT's decision to advance funds on any inventory will not be
binding until the funds are actually advanced. Dealer agrees that ITT may, at
any time and without notice to Dealer, elect not to finance any inventory sold
by particular vendors who are in default of their obligations to ITT, or with
respect to which ITT reasonably feels insecure.

2. Dealer and ITT agree that certain financial terms of any advance made by ITT
under this Agreement, whether regarding finance charges, other fees, maturities,
curtailments or other financial terms, are not set forth herein because such
terms depend, in part, upon the availability from time to time of vendor
discounts or other incentives, prevailing economic conditions, ITT's
floorplanning volume with Dealer and with Dealer's vendors, and other economic
factors which may vary over time. Dealer and ITT further agree that it is
therefore in their mutual best interest to set forth in this Agreement only
the general terms of Dealer's financing arrangement with ITT. Upon agreeing to
finance a particular item of inventory for Dealer, ITT will send Dealer a
Statement of Transaction identifying such inventory and the applicable
financial terms. Unless Dealer notifies ITT in writing of any objection within
fifteen (15) days after a Statement of Transaction is mailed to Dealer: (a) the
amount shown on such Statement of Transaction will be an account stated; (b)
Dealer will have agreed to all rates, charges and other terms shown on such
Statement of Transaction; (c) Dealer will have agreed that the items of
inventory referenced in such Statement of Transaction are being financed by ITT
at Dealer's request; and (d) such Statement of Transaction will be incorporated
herein by reference, will be made a part hereof as if originally set forth
herein, and will constitute an addendum hereto. If Dealer objects to the terms
of any Statement of Transaction, Dealer agrees to pay ITT for such inventory in
accordance with the most recent terms for similar inventory to which Dealer has
not objected (or, if there are no prior terms, at the lesser of 16% per annum
or at the maximum lawful contract rate of interest permitted under applicable
law), but Dealer acknowledges that ITT may then elect to terminate Dealer's
financing program pursuant to Section 12, and cease making additional advances
to Dealer. Any termination for that reason, however, will not accelerate the
maturities of advances previously made, unless Dealer shall otherwise be in
default of this Agreement.

3. To secure payment of all Dealer's current and future debts to ITT, whether
under this Agreement or any current or future guaranty or other agreement,
Dealer grants ITT a security interest in all Dealer's inventory, equipment,
fixtures, accounts, contract rights, chattel paper, instruments, reserves,
documents and general intangibles, whether now owned or hereafter acquired, all
attachments, accessories, accessions, substitutions and replacements thereto
and all proceeds thereof. All such assets are as defined in the Uniform
Commercial Code and referred to herein as the "Collateral." All Collateral
financed by ITT, and all proceeds thereof, will be held in trust by Dealer for
ITT, with such proceeds being payable in accordance with Section 7.

4. Dealer represents that all Collateral will be kept at Dealer's principal
place of business listed above, and, if any, the following other locations.

- ------------------------------------------------------------------------------
Dealer will give ITT at least 30 days prior written notice of any change in
Dealer's identity, name, form of business organization, ownership, principal
place of business, Collateral locations or other business locations.

5. Dealer will: (a) only exhibit and sell Collateral financed by ITT to buyers
in the ordinary course of business; (b) not rent, lease, demonstrate, transfer
or use any Collateral financed by ITT without ITT's prior written consent; (c)
execute all documents ITT requests to perfect ITT's security interest in the
Collateral; (d) deliver to ITT immediately upon each request, and ITT may
retain, each Certificate of Title or Statement of Origin issued for Collateral
financed by ITT; and (e) immediately provide ITT with copies of Dealer's annual
financial statements upon their completion (which in no event shall exceed 120
days after the end of Dealer's fiscal year), and all other information
regarding Dealer that ITT requests from time to time. All financial information
Dealer delivers to ITT will accurately represent Dealer's financial condition
either as of the date of delivery, or, if different, the date specified
therein, and Dealer acknowledges ITT's reliance thereon.

6. Dealer will: (a) pay all taxes and fees assessed against Dealer or the
Collateral when due; (b) immediately notify ITT of any loss, theft or damage to
any Collateral; (c) keep the Collateral insured for its full insurable value
under a property insurance policy with a company acceptable to ITT, naming ITT
as a loss-payee and containing standard lender's loss payable and termination
provisions; and (d) provide ITT with written evidence of such insurance
coverage and loss-payee and lender's clauses. If Dealer fails to pay any
taxes, fees or other obligations which may impair ITT's interest in the
Collateral, or fails to keep the Collateral insured, ITT may pay such taxes,
fees or obligations and pay the cost to insure the Collateral, and the
amounts paid will be: (i) an additional debt owed by Dealer to ITT; and (ii)
due and payable immediately in full. Dealer grants ITT an irrevocable license
to enter Dealer's business locations during normal business hours without notice
to Dealer to: (A) account for and inspect all Collateral; (B) verify Dealer's
compliance with this Agreement; and (C) examine and copy Dealer's books and
records related to the Collateral.

7. Dealer will immediately pay ITT the principal indebtedness owed ITT on each
item of Collateral financed by ITT (as shown on the Statement of Transaction
identifying such Collateral) on the earliest occurrence of any of the following
events: (a) when such Collateral is lost, stolen or 

<PAGE>   2
damaged; (b) for Collateral financed under Pay-As-Sold ("PAS") terms (as shown
on the Statement of Transaction identifying such Collateral), when such
Collateral is sold, transferred, rented, leased, otherwise disposed of or
matured; (c) in strict accordance with any curtailment schedule for such
Collateral (as shown on the Statement of Transaction identifying such
Collateral); (d) for Collateral financed under Scheduled Payment Program ("SPP")
terms (as shown on the Statement of Transaction identifying such Collateral), in
strict accordance with the installment payment schedule and (e) when otherwise
required under the terms of any financing program agreed to in writing by the
parties. Regardless of the SPP term pertaining to any Collateral financed by
ITT, if ITT determines that the current outstanding debt owed by Dealer to ITT
exceeds the aggregate wholesale invoice price of such Collateral in Dealer's
possession, Dealer will immediately upon demand pay ITT the difference between
such outstanding debt and the aggregate wholesale invoice price of such
Collateral. If Dealer from time to time is required to make immediate payment to
ITT of any past due obligation discovered during any Collateral audit, or at any
other time, Dealer agrees that acceptance of such payment by ITT shall not be
construed to have waived or amended the terms of its financing program. Dealer
agrees that the proceeds of any Collateral received by Dealer shall be held by
Dealer in trust for ITT's benefit, for application as provided in this
Agreement. Dealer will send all payments to ITT's branch office(s) responsible
for Dealer's account. ITT may apply: (i) payments to reduce finance charges
first and then principal, regardless of Dealer's instructions; and (ii)
principal payments to the oldest (earliest) invoice for Collateral financed by
ITT, but, in any event, all principal payments will first be applied to such
Collateral which is sold, lost, stolen, damaged, rented, leased, or otherwise
disposed of or unaccounted for. Any third party discount, rebate, bonus or
credit granted to Dealer for any Collateral will not reduce the debt Dealer owes
ITT until ITT has received payment therefor in cash. Dealer will: (i) pay ITT
even if any Collateral is defective or fails to conform to any warranties
extended by any third party; (ii) not assert against ITT any claim or defense
Dealer has against any third party; and (iii) indemnify and hold ITT harmless
against all claims and defenses asserted by any buyer of the Collateral relating
to the condition of, or any representations regarding, any of the Collateral.
Dealer waives all rights of offset Dealer may have against ITT.

8.  Dealer will pay ITT finance charges on the outstanding principal debt Dealer
owes ITT for each item of Collateral financed by ITT at the rate(s) shown on the
Statement of Transaction identifying such Collateral, unless Dealer objects
thereto as provided in Section 2. The finance charges attributable to the rate
shown on the Statement of Transaction will: (a) be computed based on a 360 day
year; (b) be calculated by multiplying the Daily Charge (as defined below) by
the actual number of days in the applicable billing period; and (c) accrue from
the invoice date of the Collateral identified on such Statement of Transaction
until ITT receives full payment of the principal debt Dealer owes ITT for each
item of such Collateral. The "Daily Charge" is the product of the Daily Rate (as
defined below) multiplied by the Average Daily Balance (as defined below). The
"Daily Rate" is the quotient of the annual rate shown on the Statement of
Transaction divided by 360, or the monthly rate shown on the Statement of
Transaction divided by 30. The "Average Daily Balance" is the quotient of (i)
the sum of the outstanding principal debt owed ITT on each day of a billing
period for each item of Collateral identified on a Statement of Transaction,
divided by (ii) the actual number of days in such billing period. Dealer will
also pay ITT $100 for each check returned unpaid for insufficient funds (an "NSF
check") (such $100 payment repays ITT's estimated administrative costs; it does
not waive the default caused by the NSF check). Dealer acknowledges that ITT
intends to strictly conform to the applicable usury laws governing this
Agreement and understands that Dealer is not obligated to pay any finance
charges billed to Dealer's account exceeding the amount allowed by such usury
laws, and any such excess finance charges Dealer pays will be applied to reduce
Dealer's principal debt owed to ITT. The annual percentage rate of the finance
charges relating to any item of Collateral financed by ITT shall be calculated
from the invoice date of such Collateral, regardless of any period during which
any finance charge subsidy shall be paid or payable by any third party. ITT will
send Dealer a monthly billing statement identifying all charges due on Dealer's
account with ITT. The charges specified on each billing statement will be: (A)
due and payable in full immediately on receipt, and (B) an account stated,
unless ITT receives Dealer's written objection thereto within 15 days after it
is mailed to Dealer. If ITT does not receive, by the 25th day of any given
month, payment of all charges accrued to Dealer's account with ITT during the
immediately preceding month, Dealer will (to the extent allowed by law) pay ITT
a late fee ("Late Fee") equal to the greater of $5 or 5% of the amount of such
finance charges (such Late Fee repays ITT's estimated administrative costs; it
does not waive the default caused by the late payment). ITT may adjust the
billing statement at any time to conform to applicable law and this Agreement.

9.  Dealer will be in default under this Agreement if: (a) Dealer breaches any
terms, warranties or representations contained herein, in any Statement of
Transaction to which Dealer has not objected as provided in Section 2, or in
any other agreement between ITT and Dealer; (b) any guarantor of Dealer's debts
to ITT breaches any terms, warranties or representations contained in any
guaranty or other agreement between the guarantor and ITT; (c) any
representation, statement, report or certificate made or delivered by Dealer or
any guarantor to ITT is not accurate when made; (d) Dealer fails to pay any
portion of Dealer's debts to ITT when due and payable hereunder or under any
other agreement between ITT and Dealer; (e) Dealer abandons any Collateral;
(f) Dealer or any guarantor is or becomes in default in the payment of any debt
owed to any third party; (g) a money judgment issues against Dealer or any
guarantor; (h) an attachment, sale or seizure issues or is executed against any
assets of Dealer or of any guarantor; (i) the undersigned dies while Dealer's
business is operated as a sole proprietorship or any general partner dies while
Dealer's business is operated as a general or limited partnership; (j) any
guarantor dies; (k) Dealer or any guarantor shall cease existence as a
corporation, partnership or trust; (l) Dealer or any guarantor ceases or
suspends business; (m) Dealer or any guarantor makes a general assignment for
the benefit of creditors; (n) Dealer or any guarantor becomes insolvent or
voluntarily or involuntarily becomes subject to the Federal Bankruptcy Code,
any state insolvency law or any similar law; (o) any receiver is appointed for
any of Dealer's or any guarantor's assets; (p) any guaranty of Dealer's debts
to ITT is terminated; (q) Dealer loses any franchise, permission, license or
right to sell or deal in any Collateral which ITT finances; (r) Dealer or any
guarantor misrepresents Dealer's or such guarantor's financial condition or
organizational structure; or (s) any of the Collateral becomes subject to any
lien, claim, encumbrance or security interest prior or superior to ITT's. In the
event of a default:

    (i)  ITT may at any time at ITT's election, without notice or demand to
         Dealer, do any one or more of the following: declare all or any part
         of the debt Dealer owes ITT immediately due and payable, together with
         all costs and expenses of ITT's collection activity, including, without
         limitation, all reasonable attorney's fees; exercise any or all rights
         under applicable law (including, without limitation, the right to
         possess, transfer and dispose of the Collateral); and/or cease
         extending any additional credit to Dealer (ITT's right to cease
         extending credit shall not be construed to limit the discretionary
         nature of this credit facility).

   (ii)  Dealer will segregate and keep the Collateral in trust for ITT, and in
         good order and repair, and will not exhibit, sell, rent, lease, further
         encumber, otherwise dispose of or use any Collateral.


  
<PAGE>   3

(iii)   Upon ITT's oral or written demand, Dealer will immediately deliver the
        Collateral to ITT, in good order and repair, at a place specified by
        ITT, together with all related documents, as ITT may, in ITT's sole
        discretion and without notice or demand to Dealer, take immediate
        possession of the Collateral together with all related documents.

(iv)    ITT may, without notice, apply a default finance charge to Dealer's
        outstanding principal indebtedness equal to the default rate specified
        in Dealer's financing program with ITT, if any, or if there is none so
        specified, at the lesser of 3% per annum above the rate in effect
        immediately prior to the default, or the highest lawful contract rate
        of interest permitted under applicable law.

All ITT's rights and remedies are cumulative. ITT's failure to exercise any of
ITT's rights or remedies hereunder will not waive any of ITT's rights or
remedies as to any past, current or future default.

10.  Dealer agrees that if ITT conducts a private sale of any Collateral by
requesting bids from 10 or more dealers or distributors in that type of
Collateral, any sale by ITT of such Collateral in bulk or in parcels within 120
days of: (a) ITT's taking possession and control of such Collateral; or (b)
when ITT is otherwise authorized to sell such Collateral; whichever occurs
last, to the bidder submitting the highest cash bid therefor, is a commercially
reasonable sale of such Collateral under the Uniform Commercial Code. Dealer
agrees that the purchase of any Collateral by a vendor, as provided in any
agreement between ITT and the vendor, is a commercially reasonable disposition
and private sale of such Collateral under the Uniform Commercial Code, and no
request for bids shall be required. Dealer further agrees that 7 or more days
prior written notice will be commercially reasonable notice of any public or
private sale (including any sale to a vendor). If ITT disposes of any such
Collateral other than as herein contemplated, the commercial reasonableness of
such disposition will be determined in accordance with the laws of the state
governing this Agreement.

11.  Dealer grants ITT an irrevocable power of attorney to: execute or endorse
on Dealer's behalf any checks, financing statements, instruments, Certificates
of Title and Statements of Origin pertaining to the Collateral; supply any
omitted information and correct errors in any documents between ITT and Dealer;
do anything Dealer is obligated to do hereunder; initiate and settle any
insurance claim pertaining to the Collateral; and do anything to preserve and
protect the Collateral and ITT's rights and interest therein. ITT may provide
to any third party any credit, financial or other information on Dealer that
ITT may from time to time possess.

12.  Time is of the essence. This Agreement is deemed to have been entered into
at the ITT branch office executing this Agreement. Either party may terminate
this Agreement at any time by written notice received by the other party. If
ITT terminates this Agreement,Dealer agrees that if Dealer: (a) is not in
default hereunder, 30 days prior notice of termination is reasonable and
sufficient (although this provision shall not be construed to mean that shorter
periods may not, in particular circumstances, also be reasonable and
sufficient); or (b) is in default hereunder, no prior notice of termination is
required. Dealer will not be relieved from any obligation to ITT arising out of
ITT's advances or commitments made before the effective termination date of
this Agreement. ITT will retain all of its rights, interests and remedies
hereunder until Dealer has paid all Dealer's debts to ITT. Dealer cannot assign
Dealer's interest in this Agreement without ITT's prior written consent,
although ITT may assign or participate ITT's interest, in whole or in part,
without Dealer's consent. This Agreement will protect and bind ITT's and
Dealer's respective heirs, representatives, successors and assigns. All
agreements or commitments to extend or renew credit or refrain from enforcing
payment of a debt must be in writing. Any oral or other amendment or waiver
claimed to be made to this Agreement that is not evidenced by a written
document executed by ITT and Dealer (except for each Statement of Transaction
that Dealer does not object to in the manner stated in Section 2) will be null,
void and have no force or effect whatsoever. If any provision of this Agreement
or its application is invalid or unenforceable, the remainder of this Agreement
will not be impaired or affected and will remain binding and enforceable. If
Dealer previously executed any security agreement with ITT, this Agreement will
only amend and supplement such agreement. If the terms hereof conflict with the
terms of any such prior security agreement, the terms of this Agreement will
govern. Dealer agrees to pay all of ITT's reasonable attorneys fees and
expenses incurred by ITT in enforcing ITT's rights hereunder.

13.  BINDING ARBITRATION.  Except as otherwise specified below, all actions,
disputes, claims and controversies under common law, statutory law or in equity
of any type or nature whatsoever (including, without limitation, all torts,
whether regarding negligence, breach of fiduciary duty, restraint of trade,
fraud, conversion, duress, interference, wrongful replevin, wrongful
sequestration, fraud in the inducement, or any other tort, all contract actions,
whether regarding express or implied terms, such as implied covenants of good
faith, fair dealing, and the commercial reasonableness of any Collateral
disposition, or any other contract claim, all claims of deceptive trade
practices or lender liability, and all claims questioning the reasonableness or
lawfulness of any act), whether arising before or after the date of this
Agreement, and whether directly or indirectly relating to: (a) this Agreement
and/or any amendments and addenda hereto, or the breach, invalidity or
termination hereof; (b) any previous or subsequent agreement between ITT and
Dealer; and/or (c) any other relationship, transaction or dealing between ITT
and Dealer (collectively the "Disputes"), will be subject to and resolved by
binding arbitration.

13.1  All arbitration hereunder will be pursuant to either: (a) the Code of
Procedure in effect from time to time ("Code") of the National Arbitration
Forum ("NAF"), currently located at 2124 Dupont Avenue South, Minneapolis,
Minnesota 55405; or (b) the Commercial Arbitration Rules ("Rules") in effect
from time to time of the American Arbitration Association ("AAA"), currently
located at 140 West 51st Street, New York, New York 10020-1203. The party first
filing any claim for arbitration shall designate which arbitration procedures
are to be applied for all Disputes between Dealer and ITT, although if either
the NAF or AAA is dissolved, the procedures of the remaining arbitration body
must be used. A copy of the Code, Rules and any fee schedule of the NAF or AAA
may be obtained by contacting the NAF or AAA, as applicable. The parties agree
that all arbitrators selected shall be attorneys. The arbitrator(s) will decide
if any inconsistency exists between the Code, or Rules, as applicable, and the
arbitration provisions contained herein. If any such inconsistency exists, the
arbitration provisions contained herein will control and supersede the Code, or
Rules, as applicable. The site of all arbitration participatory hearings will
be in the Division of the Federal Judicial District of ITT's branch office
closest to Dealer. The laws of the State of Massachusetts will govern this
Agreement; provided, however, that the Federal Arbitration Act ("FAA"), to the
extent inconsistent, will supersede the laws of such state and govern. This
Agreement concerns transactions involving commerce among the several states. All
arbitration proceedings, including testimony or evidence at hearings, will be
kept confidential.




 
<PAGE>   4
although any award or order rendered by the arbitrator(s) or director of
arbitration pursuant to the terms of this Agreement may be entered as a
judgment or order and enforced by either party in any state or federal court
having competent jurisdiction.

13.2  Nothing herein will be construed to prevent ITT's or Dealer's use of
bankruptcy, receivership, injunction, repossession, replevin, claim and
delivery, sequestration, seizure, attachment, foreclosure, dation and/or any
other prejudgment or provisional action or remedy relating to any Collateral
for any current or future debt owed by either party to the other. Any such
action or remedy will not waive ITT's or Dealer's right to compel arbitration
of any Dispute. If either Dealer or ITT brings any other action for judicial
relief with respect to any Dispute, the party bringing such action will be
liable for and immediately pay all of the other party's costs and expenses
(including attorneys' fees) incurred to stay or dismiss such action and remove
or refer such Dispute to arbitration. If either Dealer or ITT brings or appeals
an action to vacate or modify an arbitration award and such party does not
prevail, such party will pay all costs and expenses, including attorneys' fees,
incurred by the other party in defending such action.

13.3  Any arbitration proceeding must be instituted:  (a) with respect to any
Dispute for the collection of any debt owed by either party to the other,
within two (2) years after the date the last payment was received by the
instituting party; and (b) with respect to any other Dispute, within two (2)
years after the date the incident giving rise thereto occurred, whether or not
any damage was sustained or capable of ascertainment or either party knew of
such incident. Failure to institute an arbitration proceeding within such
period will constitute an absolute bar and waiver to the institution of any
proceeding with respect to such Dispute. Except as otherwise stated herein, all
notices, arbitration claims, responses, requests and documents will be
sufficiently given or served if mailed or delivered:  (i) to Dealer at Dealer's
principal place of business specified above; and (ii) to ITT at 8251 Maryland
Avenue, Clayton, Missouri 63105, Attention: General Counsel, or such other
address as the parties may specify from time to time in writing. No arbitration
hereunder will include, by consolidation, joinder or otherwise, any third
party, unless such third party agrees to arbitrate pursuant to the arbitration
provisions contained herein and the Code, or Rules, as applicable.

14.  If Section 13 of this Agreement or its application is invalid or
unenforceable, any legal proceeding with respect to any Dispute will be tried
in a court of competent jurisdiction by a judge without a jury. Dealer and ITT
waive any right to a jury trial in any such proceeding.

THIS CONTRACT CONTAINS BINDING ARBITRATION AND JURY WAIVER PROVISIONS.

ITT Commercial Finance Corp.

Canton, Ma.  02021


RE:      MANCHESTER EQUIPMENT COMPANY, INC. (the "Company")


Gentlemen/Ladies:

         We hold available for the Company a line of credit under which we have
made and may take advances to the Company.

         As security for its present and future indebtedness to us, the Company
has granted to us a security interest in, among other things, (i) all of its now
existing and hereafter arising or created accounts, contract rights,
instruments, documents, chattel paper and general intangibles (including but not
limited to trademarks), all proceeds thereof and all returned or repossessed
goods, the sale of which gave rise to any of the foregoing (hereinafter,
collectively, the "Receivables"); (ii) all of its now owned and hereafter
acquired inventory, wherever located including all work in process, finished
goods and raw materials, and the proceeds thereof (hereinafter, collectively,
the "Inventory"); and (iii) all equipment, machinery, furniture, fixtures, dies,
tools, and other tangible personal property of the Company, wherever located and
whether now owned or hereafter acquired by the Company, and all proceeds of the
foregoing ("M&E"). Inventory and M&E shall include but not be limited to "ITT
products" (as hereinafter defined) and for purposes of this agreement, Inventory
and M&E excluding ITT Products shall hereinafter be referred to as "Other
Inventory and M&E".

         The Company has advised us that, as security for its indebtedness to
you, the Company has granted to you a security interest in all of its now owned
and hereafter acquired inventory and equipment manufactured, distributed or sold
by Apple Computers, Inc. or any of its subsidiaries or affiliated companies
and/or bearing any trademark or tradename of Apple Computers, Inc. or any of its
subsidiaries or affiliated companies, wherever located, including all discounts,
rebates, credits, incentive payments,
<PAGE>   2
returns, repossessions, exchanges, substitutions, replacements, attachments,
parts, accessories, and accessions thereto, and the proceeds thereof
(hereinafter, collectively, the "ITT Products").

         You hereby agree that, so long as any of the indebtedness to us remains
outstanding:

         1. Any security interest you may now or hereafter have in the
         Receivables and Other Inventory and M&E, however, arising, and the
         proceeds of ITT Products (including but not limited to Receivables)
         other than the insurance proceeds of the ITT products shall be subject
         and subordinate in all respects to our security interest, if and to the
         extent perfected and non-avoidable, in the Receivables, Other Inventory
         and M&E and proceeds of ITT Products (including but not limited to
         Receivables) other than the insurance proceeds of the ITT Products,
         notwithstanding the provisions of applicable law with respect to the
         priority of our respective security interests and irrespective of the
         order of attachment or perfection thereof.

         2. Any security interest we may now or hereafter have in the ITT
         Products and the insurance proceeds of the ITT Products however
         arising, excluding Receivables and other proceeds of ITT Products,
         shall be subject and subordinate in all respects to your security
         interest, if and to the extent perfected and non-avoidable, in the ITT
         Products excluding Receivables and other proceeds of ITT Products,
         notwithstanding the provisions of applicable law with respect to the
         priority of our respective security interests and irrespective of the
         order of attachment or perfection thereof.

         3. You shall not notify any obligors on the Receivables and other
         proceeds of ITT Products of your security interest in the ITT Products.

         4. You shall not take any action which will in any way hinder
         enforcement of our security interest in the Receivables and other
         proceeds of ITT Products.

         Our respective rights hereunder shall in no way be altered or affected
by virtue of any action being taken by or against the Company under any state or
federal bankruptcy or insolvency law.

         This agreement is intended solely to establish our respective rights as
between ourselves; shall not in any way affect or impair the validity or
enforceability of our respective security interests as against any other person
or entity; and no such other person or entity (whether the Company, a trustee in
bankruptcy or otherwise) shall have any rights or benefits hereunder.


                                       2

         This agreement may be terminated by either party upon ninety (90) days
written notice to the other party.

         This agreement shall be binding upon our and your successors and
assigns and shall be governed and construed in accordance with the laws of the
State of New York.

Mr. Barry R. Steinberg
Manchester Equipment Co., Inc.
50 Marcus Blvd.
Hauppauge, NY 11788

RE:     APPROVAL OF LINE OF CREDIT WITH AT&T COMMERCIAL FINANCE CORPORATION

Dear Mr. Steinberg:

        AT&T Commercial Finance Corporation ("AT&T-CFC") is pleased to advise
        you of our commitment to offer Manchester Equipment Co., Inc. (the
        "Borrower") a line of credit in an amount not to exceed $4,000,000 (the
        "Line of Credit"). This commitment is made subject to the following
        terms and conditions;

1.      Amount of Line of Credit
        The Line of Credit shall be in a maximum amount of $4,000,000. AT&T-CFC
        may from time to time finance sums above the committed line at its sole
        discretion. Further, any such additional advances are not intended to be
        and should not be construed as a permanent commitment above the approved
        line and are subject to immediate repayment, at our sole option, upon
        notice by AT&T-CFC. There shall be no minimum extension of credit
        required of AT&T-CFC under this commitment. All extensions of credit
        shall be made in the sole and complete discretion of AT&T-CFC. The
        outstanding balance under the Line of Credit shall be computed by adding
        the principal outstanding amount and the amount of unpurchased
        approvals.

2.      Duration of Line of Credit
        The term of the Line of Credit shall commence on April 1, 1996 and shall
        continue through four calendar months after the close of your fiscal
        year ending July 31, 1997 ("Expiration") at which time the Line of
        Credit shall terminate and expire. AT&T-CFC will annually review the
        line from renewal based on our receipt and satisfactory review of your
        next fiscal year end, at our sole option. AT&T-CFC may, in its sole and
        absolute discretion extend the Line of Credit for such additional
        periods of time and under such terms and conditions as AT&T-CFC
        determines to be appropriate. No advances will be made by AT&T-CFC until
        AT&T-CFC actually receives executed copies of any and all documentation
        required by AT&T-CFC.

3.      Early Termination
        The Line of Credit may be terminated by AT&T-CFC at any time prior to
        the Expiration specified above if;

                a.)  The Borrower fails to execute and/or deliver any and all
                financing documents required by AT&T-CFC, which financing
                documents shall include, but shall not be limited to, an
                Agreement for Wholesale Financing.

                b.)  The Borrower is in breach of any of the provisions of any
                of the financing documents required by AT&T-CFC or is in default
                under any such document. 

<PAGE>   2
                c.)  The Borrower fails to provide in form and substance
                satisfactory to AT&T-CFC, at its sole discretion, quarterly
                interim financial statements within 30 days of closing, and
                annual financial statements within 90 days of closing.

                d.)  There has occurred any adverse change in the financial
                condition or business prospects of the Borrower or any guarantor
                of the Borrower's indebtedness to AT&T-CFC or if AT&T-CFC shall
                learn of any misrepresentation or omission of a fact or
                circumstance by the Borrower (or any guarantor of the Borrower's
                indebtedness to AT&T-CFC) or if AT&T-CFC shall learn of any
                misrepresentation or omission of a fact or circumstance by the
                Borrower (or any guarantor) that AT&T-CFC deems to be material.
                The Borrower and all guarantors shall be obligated to notify
                AT&T-CFC in writing of any change in either of their financial
                condition, structure, ownership, or business prospects.

4.      No Assignment
        This commitment may not be assigned by the Borrower without the prior
        written consent of AT&T-CFC, which consent shall be granted or withheld
        in the sole and absolute discretion of AT&T-CFC.


Very truly yours,

                            INTERCREDITOR AGREEMENT


This Agreement is made this 18th day of May, 1994 by and between AT&T Commercial
Finance Corporation ("AT&T") and The Bank of New York ("Lender")

                                  WITNESSETH:

WHEREAS, AT&T and Lender have extended or intend to extend credit to Manchester
Equipment Co., Inc. having a principal place of business at 50 Marcus Blvd.,
Hauppauge, NY 11788 ("Dealer"); and

WHEREAS, in order to secure the repayment of its indebtedness to AT&T and to
Lender, Dealer has granted or has proposed to grant AT&T and Lender liens,
security interests, or other rights (collectively "Security Interests" or a
"Security Interest") with regard to all or certain of Dealer's personal property
(the "Collateral"); and

WHEREAS, AT&T and Lender desire to establish as between themselves the relative
priorities of their respective Security Interests;

NOW, THEREFORE, in consideration of the mutual promises contained herein and for
other good and valuable consideration, receipt of which is hereby acknowledged,
AT&T and Lender hereby agree as follows:

1.       Except as provided in Paragraph 2 herein, any Security Interest in any
         and all personal property of Dealer which Lender now has or may
         hereafter acquire shall be senior in priority to any Security Interest
         in such personal property that AT&T now has or may hereafter acquire.

2.a)     Any Security Interest that Lender now has or may hereafter acquire in
         inventory, goods, or other personal property of Dealer which was at any
         time manufactured, sold, and/or distributed by Compaq, Toshiba or any
         of its assignees, successors, parents, subsidiaries, or affiliated
         entities or which is part of the Compaq, Toshiba product line or which
         bears the trade names, brand names, trade styles, marks or logos of
         Compaq, Toshiba or any replacements or substitutions thereof (the "AT&T
         Product Line Inventory") shall be subordinate and junior in priority to
         any Security Interest that AT&T now has or may hereafter acquire in
         such property. For purposes of this agreement, the term "inventory"
         shall include all inventory as defined in the Uniform Commercial Code
         currently in effect in the State of New Jersey, whether now owned or
         hereafter acquired by Dealer and i) all parts, accessories,
         attachments, additions, replacements, substitutions, and accessions
         thereto or therefor (wherever located and whether or not affixed to
         realty), and ii) all proceeds payable or to become payable under any
         policy of insurance relating thereto.

b)       My Security Interest in Dealer's accounts (as that term is defined in
         Section 9-106 of the Uniform Commercial Code currently in effect in the
         State of New Jersey) which AT&T now has or may hereafter acquire, shall
         be subordinate and junior in priority to any Security Interest of
         Lender in such accounts. For purposes of this agreement, an account
<PAGE>   2
         shall be deemed to have arisen when the goods are shipped or when an
         invoice for the goods has been transmitted.

3.       AT&T and Lender shall each use reasonable efforts to give the other
         prompt written notice of any default by Dealer under any agreement with
         AT&T or Lender, any notification of default forwarded to Dealer and any
         cure waiver, or resolution of any such default. The failure by either
         party to give the other party notice pursuant to this paragraph shall
         not affect in any manner the relative rights, priorities, or
         subordinations set forth in this Agreement.

4.       Lender will not seek to enforce its Security Interest in Collateral in
         which AT&T holds a senior Security Interest until Lender has been
         advised in writing by AT&T that Dealer's indebtedness to AT&T has been
         fully paid and satisfied. AT&T will not seek to enforce its Security
         Interest in Collateral in which Lender holds a senior Security Interest
         until AT&T has been notified in writing by Lender that Dealer's
         indebtedness to Lender has been fully paid and satisfied. This
         paragraph shall not be applicable if the forbearance contemplated
         herein by AT&T or Lender will have the effect of giving a creditor or
         other person not a party to this Agreement rights which are superior to
         the rights of AT&T or Lender.

5.       The subordinations, relative rights and priorities set forth herein
         shall be applicable irrespective of the time, manner or perfection of
         the Security Interests of AT&T and Lender. Such subordinations relative
         rights and priorities shall not be applicable unless all holders of
         Security Interests which are senior to Lender's Security Interest but
         junior to AT&T's Security Interest subordinate (by way of intercreditor
         agreement or otherwise) their Security Interests to that of lender.
         Such subordinations, relative rights and priorities shall not apply to
         any item of Collateral as to which a Security Interest is invalid,
         unperfected or avoidable. Except as specifically provided herein, the
         subordinations and establishment of rights herein shall in no way be
         deemed to be a waiver of either party's rights under any agreement or
         law.

6.       This Agreement may be terminated by either party upon sixty (60) days'
         prior written notice to the other party. Any such termination shall be
         effective on the date following the date that written notice of the
         termination is dispatched. No termination of this Agreement shall
         affect or impair any of the rights or priorities existing prior to the
         effective date of termination with regard to any Collateral.

7.       This Agreement is solely for the benefit of AT&T and Lender and shall
         be binding upon those parties and their respective successors and
         assigns. AT&T and Lender may rely on this Agreement in extending or
         continuing to extend credit to Dealer. This Agreement is not intended
         to, nor shall it be construed as, benefitting any other party,
         including without limitation, Dealer or any guarantor of Dealer's
         obligations.

8.       No failure or delay by either party to exercise any right or remedy
         under this Agreement shall operate as a waiver of any such right or
         remedy. The rights and remedies set forth herein shall be cumulative
         and not exclusive of any other rights or remedies that AT&T
