                                  THE COMPANY
 
     Datalink Corporation ("Datalink" or the "Company") analyzes, custom
designs, integrates or assembles, installs and supports high-end Open Systems
data storage solutions for end-users, value-added resellers ("VARs") and
original equipment manufacturers ("OEMs"). The Company has developed
engineering, sales and support capabilities to become an expert in applying the
best available storage technologies manufactured by the leading data storage
hardware and software companies to solve its customers' growing data storage
needs. These technologies include hard disk, RAID, magnetic tape, CD-ROM and
optical products. The Company also matches storage management software
technologies, including backup and recovery, archive, high availability and near
on-line storage to the specific needs of its customers. The Company's net sales
have grown from $24.1 million in 1993 to $71.3 million in 1997, a 31% annual
compound growth rate, and the Company's Subchapter S corporation net income has
grown from $1.0 million to $6.1 million, a 56% annual compound growth rate, over
the same period.
 
     With the ongoing introduction of more advanced and powerful computers,
application software developers have introduced powerful, easier to use,
graphically oriented, memory intensive software packages. These software
applications have resulted in the enterprise-wide automation of an increasing
number of mission-critical business applications, including on-line transaction
processing, the Internet, intranets, pre-press, multimedia, imaging and data
warehousing. This automation has expanded the need for on-line storage,
uninterrupted access to data and fail-safe methods to backup and archive such
data. Accordingly, several independent market research firms have projected
significant growth over the next several years for the markets addressed by the
Company. According to Dataquest, Inc., an independent market research firm, the
worldwide RAID storage market for UNIX and Windows NT operating platforms was
approximately $12.8 billion in 1997 and is expected to grow at an annual
compound rate of 24% to approximately $37.0 billion by 2002. According to
Strategic Research Corp., an independent market research firm ("SRC"), the
worldwide market for tape automation backup storage products was approximately
$1.6 billion in 1996 and is expected to grow at an annual compound rate of 18%
to approximately $4.4 billion by 2002. According to SRC, the worldwide storage
management software market was approximately $1.4 billion in 1997 and is
expected to grow at an annual compound rate of 38% to approximately $3.7 billion
by 2000.
 
     The need to distribute mission-critical data across an enterprise has led
organizations to increasingly rely upon complex Open Systems computing platforms
that link multiple application, file, database and communications servers of
differing vendors to networked computers. Despite this growing complexity,
corporate downsizing has led organizations to reduce their MIS staffs and has
led hardware and software suppliers to reduce their sales and marketing forces.
As a result of their more limited internal resources, organizations and
suppliers are turning to external providers, such as the Company, to research,
design, implement and support information storage solutions that incorporate the
best available hardware and software technologies.
<PAGE>   5
 
     The Company's storage solutions are designed to provide its customers with
the optimal combination of performance, capacity, high availability, disaster
recovery, multi-platform support, permanence, scalability, centralized
management and cost. For end-users and VARs, Datalink's technical sales and
engineering teams assess each customer's information and storage retrieval
requirements and then design, integrate, install and support information storage
solutions incorporating the best available hardware and software products on the
market. For OEMs, Datalink's design and application engineers custom design and
test storage subsystems which the Company assembles for integration into the
OEM's own products.
 
     Datalink's customers are located throughout the United States and span a
diverse group of data-intensive industries, including computer technology,
consumer products, education, financial services, government, health care,
insurance, professional services, telecommunications, transportation and
utilities. The Company's customers include Abbott Laboratories, American Express
Company, Andersen Worldwide, S.C., The Boeing Company, Dominion Resources, Inc.,
Gateway 2000, Inc., GE Medical Systems, Grand Metropolitan PLC, The Kemper
Insurance Companies, KPMG Peat Marwick L.L.P., Lucent Technologies, Inc., the
National Aeronautics Space Administration and the University of Chicago.
Datalink's broad industry experience enables the Company to understand
application and business issues specific to its customers and to design and
implement appropriate storage solutions.
 
     The Company believes it differentiates itself from its competitors in
several ways. Because of Datalink's established, strong relationships with the
major information storage hardware and software suppliers, the Company often
participates in suppliers' new product development, evaluation, introduction,
marketing and quality control programs. The Company also believes that the
longevity of service of its engineering staff and sales force is a key factor to
earning and retaining the trust and confidence of the Company's customers and
suppliers. Sales to existing customers has exceeded 77% of the Company's net
sales in each of the last three years. Datalink further differentiates itself by
being an ISO 9001 registered organization that utilizes such standards to
consistently maintain high quality design, development, integration and
assembly, installation and service processes.
 
     The Company's objective is to grow at a rate exceeding that of the industry
and enhance its position as a leading independent Open Systems storage solutions
provider. To achieve its objective, Datalink intends to build upon its record of
successfully addressing the evolving information storage management needs of its
customers. Key elements of the Company's business strategy are to (i) broaden
relationships with existing customers and leverage the Company's significant
market presence to attract new customers; (ii) continue to develop leading-edge
storage solutions for customers; (iii) expand its offering of professional
consulting services; (iv) expand geographically through internal growth and
potential acquisitions; and (v) maintain and continually improve the Company's
high standards for superior technical and sales service and support. The
Company's senior management team, which has worked together since 1991, has
assembled an experienced team of professionals to execute the Company's business
strategy.
 
     The Company was incorporated in Minnesota in 1963 under the name Stan
Clothier Co., Inc. In April 1987, the Company changed its name to Datalink
Corporation. The Company's executive offices are located at 7423 Washington
Avenue South, Minneapolis, Minnesota 55439. Datalink's telephone number is (612)
944-3462.

                               RECENT DEVELOPMENT
 
     In June 1998, the Company entered into a nonbinding letter of intent to
acquire Direct Connect Systems, Inc. ("DCSI"), a Marietta, Georgia-based firm
engaged in the analysis, custom design, integration and support of high-end Open
Systems data storage solutions principally for end-users located in the
Southeastern portion of the United States. In addition to its Marietta
headquarters, DCSI has field sales offices in Herndon, Virginia, Charlotte,
North Carolina, and Melbourne and Tampa, Florida.
 
     Under the terms of the proposed acquisition, the Company would acquire all
of DCSI's capital stock in exchange for $2 million cash and 200,000 shares of
the Company's Common Stock, subject to certain adjustments. DCSI's key employees
would also be paid $500,000 in the aggregate under noncompetition agreements.
The acquisition is subject to various conditions, including the Company's due
diligence investigation of DCSI's business and financial affairs and prospects
and negotiation and execution of a definitive agreement.

                                  RISK FACTORS
 
     This Prospectus contains certain forward-looking statements, including the
plans and objectives of management for the business, operations and economic
performance of the Company. The forward-looking statements and associated risks
set forth in this Prospectus may include or relate to, among other things, the
ability of the Company to maintain its close working relationships with its
suppliers, expand its customer base, consummate strategic acquisitions of
businesses and integrate such acquisitions into the Company's operations, the
projected growth in the market for data storage solutions and competition. These
forward-looking statements may be identified by qualifiers such as "intends,"
"believes" and "anticipates," among other terms. In light of the significant
uncertainties inherent in the forward-looking information included herein, the
inclusion of such information should not be regarded as a representation by the
Company or any other person that the objectives or plans of the Company will be
achieved. Further, and in addition to the other information contained in this
Prospectus, the following risk factors should be carefully considered in
evaluating the Company and its business prospects before purchasing shares
offered by this Prospectus.
 
DEPENDENCE ON SUPPLIER RELATIONSHIPS
 
     The Company relies on its relationships with its suppliers to provide
access to products and new technology necessary to design and implement
leading-edge storage solutions for its customers. The Company does not have
long-term contracts with any of its suppliers and relies upon a limited number
of suppliers for several key products and components. For example, the Company
purchases disk drives manufactured primarily by Quantum Corporation ("Quantum")
and Seagate Technology, Inc. ("Seagate"), digital linear tape products
manufactured primarily by Storage Technology Corporation, Quantum and ATL
Products, Inc. and redundant array of independent disks ("RAID") products
manufactured primarily by CLARiiON, a division of Data General Corporation. The
Company's reliance on its suppliers involves several risks, including an
inadequate supply of required products and components, price increases, late
deliveries and poor product and component quality. These risks are particularly
significant with respect to the Company's suppliers of disk drives because, in
order to meet product performance requirements, the Company must obtain disk
drives with extremely high quality and capacity. In addition, there is currently
a significant market demand for disk drives, tape drives and RAID controllers,
and from time to time the Company may experience product and component
shortages, selective supply allocations and increased prices of such products
and components. Although to date the Company has been able to purchase its
requirements of such products and components, there can be no assurance that the
Company will be able to obtain its full requirements of such products and
components in the future or that prices of such products and components will not
increase. In addition, there can be no assurance that problems with respect to
quantity and quality of such products and components and timeliness of
deliveries will not occur. Disruption or termination of the supply of products
and components from suppliers for any reason could delay shipments of the
Company's products and could have a material adverse effect on the Company's
business, operating results or financial condition. See "Business -- Business
Strategy" and "-- Products."
 
COMPETITION
 
     The market for Open Systems storage is intensely competitive. The Company
competes primarily with traditional suppliers of computer systems such as Compaq
Computer Corporation ("Compaq"), Digital Equipment Corporation ("Digital"),
Hewlett-Packard Company ("Hewlett-Packard"), International Business Machines
Corp. ("IBM"), Silicon Graphics, Inc. ("Silicon Graphics") and Sun Microsystems,
Inc. ("Sun"), which market storage systems as well as other computer products.
The Company also competes with independent storage system suppliers to the
high-end Open Systems market, including Box Hill Systems Corp., EMC Corporation,
MTI Technology Corporation and numerous VARs, resellers, distributors and
consultants. In addition, the Company's customers and prospective customers may
elect to develop in-house storage systems expertise.
 
     Many of the Company's current and potential competitors have significantly
greater financial, technical, marketing, purchasing and other resources than the
Company and, as a result, may be able to respond more quickly to new or emerging
technologies and changes in customer requirements, to devote greater resources
to
                                        5
<PAGE>   9
 
the development, promotion and sale of products than the Company or to deliver
competitive products at a lower end-user price. Some of the Company's
competitors include its suppliers, who may dedicate or acquire greater sales and
marketing resources in the future to provide Open Systems storage solutions than
at present and could terminate their relationships with the Company. Other
suppliers may also enter the market and compete with the Company. The Company
expects competition will increase as a result of industry consolidation. Current
and potential competitors have established or may establish cooperative
relationships among themselves or with third parties to increase the ability of
their products to address the needs of the Company's prospective customers.
Accordingly, it is possible that new competitors or alliances among competitors
may emerge and rapidly acquire significant market share. Increased competition
may result in price reductions, reduced operating margins and loss of market
share, any of which could have a material adverse effect on the Company's
business, operating results or financial condition. See "Business --
Competition."
 
COMPETITIVE PRICING
 
     Competitive pricing pressures in the data storage market have had and may
have an adverse effect on the Company's business, operating results or financial
condition. There also has been, and may continue to be, a willingness on the
part of certain large competitors to reduce prices in order to preserve or gain
market share, which cannot be foreseen by the Company. The Company believes that
pricing pressures are likely to continue as competitors develop more competitive
product offerings. See "Business -- Competition."
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's future operating results depend in significant part upon the
continued contributions of its executive officers, other key management and
sales, engineering and other technical personnel, many of whom would be
difficult to replace. In particular, the Company is highly dependent upon the
services of Greg R. Meland, Chief Executive Officer; Robert D. DeVere, Chief
Financial Officer; Scott D. Robinson, Vice President of Engineering and Stephen
M. Howe, Vice President of Sales. The Company does not have employment,
noncompetition or nondisclosure agreements with any of its officers or
employees. Accordingly, the Company's employees may voluntarily terminate their
employment with the Company at any time. The loss of any employee who is
critical to the Company's success could have a material adverse effect on the
Company's business, operating results or financial condition. In addition, the
Company's future operating results depend in part upon its ability to attract,
train, retain and motivate qualified management, technical, sales and support
personnel for its operations. Competition for qualified employees in the data
storage industry, and particularly with respect to engineers with Open Systems
storage solutions experience, is intense. Competitive factors that could affect
the Company's ability to attract and retain such personnel include compensation,
benefits, equity incentives and geographic location. There can be no assurance
that the Company will be successful in attracting or retaining such key
personnel, and the failure of the Company to recruit and retain additional key
personnel could materially and adversely affect the Company's business,
operating results or financial condition. See "Business -- Technical Services."
 
MANAGEMENT OF GROWTH
 
     The Company's growth and expansion may place a significant strain on the
Company's administrative, operational and financial resources and increase
demands on the Company's professional and technical services, assembly,
integration, sales and marketing and customer service and support functions,
especially as the Company attempts to expand its geographic reach. To manage its
growth effectively, the Company will need to hire, train, motivate and manage
new management, technical, sales and administrative employees. In connection
with its planned geographic expansion, the Company will incur travel,
telecommunications and other incremental costs, as well as increased human
resource costs. The failure by the Company to generate sufficient revenues to
offset the costs of geographical expansion could have a material adverse effect
on the Company's business, operating results or financial condition. If the
growth in demand for products and services offered by the Company increases at a
significantly higher rate than anticipated, the Company may lack the technical
services and capacity necessary to satisfy such demand in a timely fashion, and
its customers may
 
                                        6
<PAGE>   10
 
experience delivery delays or interruptions in technical service and support.
This risk may be exacerbated by the fact that the Company does not have
long-term purchase agreements with suppliers and may not have sufficient
inventory levels to support customer demand. There can be no assurance that the
Company will be able to manage expansion successfully or that the Company's
infrastructure, including but not limited to its systems, procedures and
controls, will be adequate to support such expansion. In addition, there can be
no assurance that the Company will be able to achieve commercial success and
maintain client service and support in a geographically expanded area of
operations at levels that it historically achieved and provided in its current
geographical areas. Failure to manage growth may have a material adverse effect
on the Company's business, operating results or financial condition. See
"Business -- Business Strategy."
 
RAPID TECHNOLOGICAL CHANGE
 
     The Open Systems storage market in which the Company operates is
characterized by rapid technological change, frequent new product introductions
and evolving industry standards. Customer preferences in that market are
difficult to predict. As an independent solutions provider, the Company is
dependent upon its suppliers' hardware, software and interface products to meet
the needs of the Company's customers. The introduction of products embodying new
technologies by the Company's competitors and the emergence of new industry
standards could render hardware, software and interface products currently
marketed by the Company obsolete and unmarketable. The Company's success will
depend upon its ability to address the increasingly sophisticated needs of its
customers and to identify and introduce, on a timely basis, new competitive
products and applications of existing and new suppliers (including new software
and enhancements to existing software) that keep pace with technological
developments and emerging industry standards. There can be no assurance that the
Company will be successful in identifying, managing, developing, integrating or
assembling and marketing product enhancements or new products of its suppliers
that respond to technical change or evolving industry standards, that the
Company and its suppliers will not experience difficulties that could delay or
prevent the successful development, introduction or marketing of such products
or that its suppliers' new products and product enhancements will adequately
meet the requirements of the marketplace and achieve market acceptance. Further
risks inherent in its suppliers' new product introductions include the
uncertainty of price performance relative to products of competitors, including
competitors' responses to these new product introductions. The Company's
business, operating results or financial condition could be materially and
adversely affected if the Company or its suppliers were to be unsuccessful, or
to incur significant delays, in developing and introducing new products or
enhancements. See "Business -- Products."
 
RISKS ASSOCIATED WITH ACQUISITIONS
 
     The Company intends to pursue strategic acquisitions of businesses that
either expand or complement its business, including the proposed acquisition of
DCSI. A substantial portion of the Company's capital resources, including a
portion of the proceeds from this offering, could be used for acquisitions. The
Company will evaluate specific acquisition opportunities based on prevailing
market and economic conditions. Acquisitions could result in the integration of
dissimilar operations or assets, assimilation of new employees, diversion of
management time and resources, increases in administrative costs, potential loss
of key employees of an acquired company and additional costs associated with
obtaining any necessary financing. These factors and the Company's lack of
experience in negotiating, consummating and integrating acquisitions could
adversely affect the Company's business, operating results or financial
condition. This risk may be compounded by the Company's geographic expansion or
product diversification. Acquisitions also could result in dilution to existing
stockholders, including those purchasing shares of Common Stock in this
offering. The Company may encounter increased competition for acquisitions in
the future, which could result in acquisition prices that the Company does not
consider acceptable. An increase in acquisition prices could adversely affect
the Company's acquisition strategy. There can be no assurance that the Company
will be able to identify suitable acquisition candidates at acceptable prices or
succeed in integrating any acquired business into the Company's existing
business or in retaining key customers of acquired businesses. There also can be
no assurance that the Company will have or be able to obtain sufficient capital
to execute its acquisition strategy. See "Prospectus Summary -- Recent
Development," "Use of Proceeds" and "Business -- Business Strategy."

FLUCTUATIONS IN OPERATING RESULTS
 
     The Company may experience significant fluctuations in future annual and
quarterly operating results because of a number of factors including, among
other things, the size and timing of customer orders, new product introductions
by suppliers and the market acceptance thereof, delays in product shipments or
other quality control difficulties, the ability of the Company to integrate any
acquired businesses, product returns, seasonality in storage system product
purchases, trends in the Open Systems storage industry in general, the
geographic and industry specific markets in which the Company is presently
active, or may be in the future, and the opening of new sales offices. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Results of Operations."
 
BROAD DISCRETION IN APPLICATION OF PROCEEDS
 
     The Company has not designated any specific use for approximately $14.4
million of the net proceeds to the Company from the sale of Common Stock
described in this Prospectus (assuming an initial public offering price of
$10.00 per share). The Company intends to use these net proceeds to fund its
growth and expansion, to increase the Company's working capital and for general
corporate purposes which the management of the Company will determine from time
to time. Accordingly, the Board of Directors and management of the Company will
have significant flexibility in applying such remaining proceeds of this
offering. The failure of the Company's management to use such funds effectively
could have a material adverse effect on the Company's business, operating
results or financial condition. See "Use of Proceeds" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
PRIOR S CORPORATION STATUS AND DISTRIBUTION TO CURRENT STOCKHOLDERS
 
     The Company historically has been treated as an S corporation for federal
and state income tax purposes. Unlike a C corporation, an S corporation is
generally not subject to income tax at the corporate level; instead, the S
corporation's income is taxed on the personal income tax returns of its
stockholders. The Company's status as an S corporation will terminate upon the
closing of this offering. If S corporation status were denied for any periods
prior to this termination by reason of a failure to satisfy the S corporation
election or eligibility requirements of the Internal Revenue Code, as amended
(the "Code"), the Company would be subject to tax on its income as if it were a
C corporation for those periods.
 
     In connection with the termination of the Company's S corporation status,
the Company intends to make a distribution to the current stockholders of all
previously taxed, but undistributed, S corporation earnings of the Company. As
of March 31, 1998, this amount was approximately $8.2 million. The Company will
adjust the actual amount of the distribution to reflect the taxable income and
any stockholder distributions from April 1, 1998 through the termination of the
S corporation status upon the closing of this offering. Purchasers of Common
Stock in this offering will not receive any of this distribution. See "Use of
Proceeds," "Termination of S Corporation Status and Put Option and Dividend
Policy," "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and Note 12 of the Notes to the Company's Financial
Statements.
 
THIRD PARTY YEAR 2000 COMPLIANCE
 
     In connection with the approach of the Year 2000, industry experts have
predicted a variety of adverse consequences, including catastrophic system
failures, that may result from organizations' computer systems having been
programmed to record and process year dates by two, rather than four, digits.
Although the Company believes that its new computer system will not experience
any Year 2000 problems, it cannot predict whether its suppliers, customers and
other organizations with whom the Company conducts business will in a timely
fashion bring their computer systems or product offerings into Year 2000
compliance. If the Company's suppliers or customers fail to complete any
required Year 2000 remediation of their computer systems or product offerings,
the Company could suffer delays in product delivery or in processing of payments
owed to the Company. In addition, if any products or components sold by the
Company to its customers were to fail, the Company could be liable to its
customers for damages and costs to the extent that the Company's
 
                                        8
<PAGE>   12
 
suppliers do not cover such liability. Any such Year 2000 failures could have a
material adverse effect on the Company's business, operating results or
financial condition. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
WARRANTY EXPOSURE
 
     Products offered by the Company may contain defects in hardware, software
or workmanship that remain undetected or that may not become apparent until
after commercial shipment. Any loss or delay in customer or market acceptance
attributable to such defects or any material replacement or repair expenses due
to any such defects could have a material adverse effect on the Company's
business, operating results or financial condition.
 
     As a solutions provider, the Company supports and administers the
pass-through of its suppliers' own standard warranties which run from one to
five years. The Company contracts with a number of its suppliers and other
independent service organizations to provide on-site maintenance and repair
services. If a supplier were to fail to meet its warranty obligations to the
Company, the Company might be liable to its customers. There can be no assurance
that suppliers will be willing or able to honor their warranties, that the
Company may not incur its own warranty costs or that the Company's repair and
maintenance subcontractors will perform their services in a timely and proper
manner. See "Business -- Technical Services."
 
RESTRICTIONS ON DIVIDENDS
 
     Other than the planned S Corporation distribution, the Company does not
anticipate paying any dividends in the foreseeable future. In addition, the
Company's credit agreement with Norwest Bank Minnesota, N.A. (the "Credit
Agreement"), prohibits the Company from paying dividends to C corporation
stockholders. Accordingly, investors who have a need for current income should
not purchase the shares offered hereby.
 
DILUTION
 
     Purchasers of the Common Stock offered hereby will incur an immediate and
substantial dilution of $7.48 per share, or 74.8%, in the net tangible book
value per share of Common Stock from the assumed initial public offering price
of $10.00 per share. If the Company issues additional shares of capital stock
for any reason, purchasers of the shares offered hereby may incur additional
dilution. See "Dilution."
 
CONTROL BY CURRENT STOCKHOLDERS
 
     Immediately following this offering, the six current stockholders of the
Company will beneficially own approximately 72.6% of the outstanding Common
Stock (approximately 69.6% if the Underwriters' over-allotment option is
exercised in full). As a result, the six current stockholders will continue to
be able to elect the entire Board of Directors and to control the outcome of all
other matters requiring stockholder approval. Such voting concentration may have
the effect of delaying or preventing a change in management or control of the
Company. See "Principal Stockholders."
 
ABSENCE OF PRIOR PUBLIC MARKET FOR THE COMMON STOCK; POTENTIAL VOLATILITY OF
TRADING PRICE
 
     Prior to this offering, there has been no public market for the Common
Stock. Although the Company has applied for the quotation and trading of the
Common Stock on the Nasdaq National Market, there can be no assurance that an
active public market will develop or that the initial public offering price will
correspond to the price at which the Common Stock will trade in the public
market subsequent to this offering. The initial public offering price for the
Common Stock has been determined by negotiations between the Company and the
Representatives. See "Underwriting."
 
     The market price of the Common Stock may be volatile and may be
significantly affected by factors such as actual or anticipated fluctuations in
the Company's operating results, announcements of technical innovations, new
products or services by the Company, its suppliers or its competitors, changes
in estimates by
 
                                        9
<PAGE>   13
 
securities analysts of the Company's future financial performance, general
market conditions and other factors. In addition, the stock market has from time
to time experienced significant price and volume fluctuations which, in no
relationship to operating performance, have adversely affected the market prices
of securities of some companies.
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of substantial amounts of Common Stock after this offering could
adversely affect the market price of the Common Stock. Although only the
2,600,000 shares (2,990,000 shares if the Underwriters' over-allotment option is
exercised in full) being sold in this offering will be available for sale in the
public market immediately after the offering, 6,900,000 shares of Common Stock
owned by the six current stockholders will be eligible for sale in the public
market beginning 180 days after the date of this Prospectus, subject to the
volume and manner of sale limitations imposed by Rule 144 under the Securities
Act of 1933, as amended (the "Securities Act"). Rule 144 generally provides that
beneficial owners of Common Stock who have held such Common Stock for one year
may sell within a three-month period a number of shares not exceeding the
greater of 1% of the total outstanding shares or the average weekly trading
volume of the shares during the four calendar weeks preceding such sale. Future
sales of restricted Common Stock under Rule 144 could negatively impact the
market price of the Common Stock. Pursuant to the terms of the underwriting
agreement between the Company and the Representatives of the Underwriters,
Common Stock owned by the six current stockholders, as well as option holders,
may not be sold for 180 days from the date of this Prospectus, but Needham &
Company, Inc. may waive this requirement. See "Shares Eligible for Future Sale."
 
UNDESIGNATED SHARES; CERTAIN ANTI-TAKEOVER PROVISIONS
 
     The Company's Amended and Restated Articles of Incorporation authorize the
issuance of 50 million undesignated shares. The Company's Board of Directors has
the authority to issue any or all of the undesignated shares, including the
authority to establish the rights, preferences and classes of the undesignated
shares, without stockholder approval. In addition, the Company is subject to
certain anti-takeover provisions of the Minnesota Business Corporation Act.
These provisions may, in certain circumstances, deter or discourage takeover
attempts and other changes in control of the Company not approved by the Board
of Directors. See "Description of Capital Stock."

                                USE OF PROCEEDS
 
     The net proceeds to be received by the Company from the sale of the
2,600,000 shares of Common Stock offered by the Company hereby at an assumed
initial offering price of $10.00 per share, after deducting estimated
underwriting discounts and commissions and offering expenses, are estimated to
be approximately $23.7 million ($26.7 million if the Underwriters'
over-allotment option is exercised in full). In addition to the purposes set
forth below, this offering is intended to provide a public market for Datalink's
Common Stock and to facilitate future access to the public capital markets. The
Company anticipates that it will use the net proceeds approximately as follows:

</TABLE>
 
     The Company plans to use a portion of the net proceeds of this offering to
fund the final S corporation distribution to the current stockholders. This
distribution will constitute all of the previously taxed, but undistributed, S
corporation earnings. As of March 31, 1998, such earnings were approximately
$8.2 million. See "Termination of S Corporation Status and Put Option and
Dividend Policy." See Note 12 of the Notes to the Company's Financial
Statements.
 
     The Company also intends to use a portion of the net proceeds of this
offering to repay all borrowings under the Credit Agreement. As of March 31,
1998, the balance under the Credit Agreement was $1.1 million. The Company will
have up to $10.0 million available under the Credit Agreement following the
offering subject to limitations based on percentages of eligible accounts
receivable and inventories. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources" and Note 5 of the Notes to the Company's Financial Statements.
 
     Approximately $14.4 million of the net proceeds of this offering will be
used to fund the Company's growth and expansion plans and for working capital
and general corporate purposes. As part of its growth and expansion plans, the
Company intends to pursue strategic acquisitions that either expand or
complement its business. See "Business -- Business Strategy."
 
     Pending such uses, the Company intends to invest the net proceeds of this
offering in short-term, investment-grade, interest-bearing securities.

     TERMINATION OF S CORPORATION STATUS AND PUT OPTION AND DIVIDEND POLICY
 
     In January 1988, the Company elected to be treated as an S corporation and
since then has been, and through the closing date of the offering will be,
subject to taxation under Subchapter S of the Code and comparable state tax
regulations. As a result, the Company's earnings have been taxed for federal and
state income tax purposes directly to the stockholders rather than to the
Company. Upon conversion from S corporation to C corporation status, the Company
will become subject to federal and state corporate income taxes.
 
     In connection with the termination of the Company's S corporation status
upon the closing of this offering, the Company will make a distribution to the
current stockholders of all previously taxed, but undistributed, S corporation
earnings of the Company. As of March 31, 1998, such earnings were approximately
$8.2 million. The actual amount of the distribution will be adjusted to reflect
the taxable income and any stockholder distributions from April 1, 1998 through
the termination of the S corporation status. Following the termination of its S
corporation status, the Company will record a net deferred tax asset on its
balance sheet which will ultimately increase retained earnings. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Results of Operations" and Note 12 of the Notes to the Company's
Financial Statements.
 
     The Company and its current stockholders entered into a Stock Purchase
Agreement (the "Stock Purchase Agreement') effective April 1, 1992 that
restricts the right of stockholders to dispose of or encumber any shares of the
Company's Common Stock and dictates the terms for transfer of the shares. The
Stock Purchase Agreement originally provided that upon the death, disability or
termination of employment, each stockholder is required to put his shares to the
Company and the Company is obligated to purchase all shares owned by that
stockholder at a price determined pursuant to the terms of the Stock Purchase
Agreement. In November 1996, the Stock Purchase Agreement was amended to allow a
retired stockholder to retain his shares until the retired stockholder or his
legal representative exercises the put option which requires the Company to
purchase his shares, or until such stockholder's death. Because the Company's
Common Stock is subject to these put options, the accreted value of the Common
Stock (determined pursuant to the terms of the Stock Purchase Agreement) has
been excluded from stockholders' equity. The Stock Purchase Agreement, including
the put options, will be terminated contemporaneously with the closing of this
offering. See "Selected Historical and Pro Forma Financial Data,"
"Capitalization" and Notes 3 and 9 of the Notes to the Company's Financial
Statements.
 
     The Company currently intends to retain any net income for use in its
business and does not anticipate paying any cash dividends on its capital stock
in the foreseeable future other than in connection with the termination of the
Company's S corporation status. Any future declaration and payment of dividends
will be subject to the discretion of the Company's Board of Directors, will be
subject to applicable law and will depend upon the Company's results of
operations, earnings, financial condition, cash requirements, future prospects
and other factors deemed relevant by the Board of Directors. In addition, the
Credit Agreement prohibits the Company from paying dividends to C corporation
stockholders.

     The following table sets forth the capitalization of the Company as of
March 31, 1998, on an actual basis, on a pro forma basis to give effect to the
termination of the put options on the Company's Common Stock, on a pro forma

and on a pro forma basis as adjusted to give effect to the sale of the 2,600,000

     The net tangible book value (deficit) of the Company as of March 31, 1998
was $(6.5) million, or $(0.95) per share. Net tangible book value (deficit) per
share is equal to the Company's total tangible assets less total liabilities and
the Company's Common Stock subject to put option, divided by the total number of
shares of Common Stock outstanding. After giving effect to (i) the termination
of the put option on the Company's Common Stock, (ii) the final S corporation
distribution to the current stockholders, estimated at $8.2 million had the
termination occurred on March 31, 1998, (iii) the net deferred tax asset which
will be recorded by the Company as a result of the termination of its S
corporation status, estimated at $240,000 had such termination occurred on March
31, 1998 and (iv) the sale by the Company of 2,600,000 shares of Common Stock
offered hereby at an assumed initial public offering price of $10.00 per share
and after deducting the estimated underwriting discounts and commissions and
estimated offering expenses payable by the Company, the adjusted net tangible
book value of the Company as of March 31, 1998 would have been $23.9 million, or
$2.52 per share. This represents an immediate increase in net tangible book
value of $3.47 per share to the existing stockholders and an immediate dilution
in net tangible book value of $7.48 per share to investors purchasing shares of
Common Stock in this offering. The following table illustrates the per share

    stockholders, representing all previously taxed, but undistributed, S
    corporation earnings, estimated at $8.2 million had the termination occurred
    on March 31, 1998 and (iii) a net deferred tax asset which will be recorded
    by the Company as a result of the termination of its S corporation status,
    estimated at $240,000 had such termination occurred on March 31, 1998. See

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with the Company's
Financial Statements, including the Notes thereto, and the other information
included herein. The following information also includes forward-looking
statements, the realization of which may be impacted by certain important
factors discussed under "Risk Factors."
 
OVERVIEW
 
     Datalink analyzes, custom designs, integrates or assembles, installs and
supports high-end Open Systems storage solutions using products and components
manufactured by various suppliers in order to meet its customers' requirements.
The Company has developed engineering, sales and support capabilities to become
an expert in applying the best available storage technologies manufactured by
the leading data storage hardware and software companies to solve its customers'
growing data storage needs. These technologies include hard disk, RAID, magnetic
tape, CD-ROM and optical products. The Company also matches storage management
software technologies, including backup and recovery, archive, high availability
and near on-line storage, to the specific needs of its customers. The Company's
net sales and net income have grown at a compound annual rate of 31% and 56%,
respectively, over the past five years.
 
     The Company was founded in 1963 as Stan Clothier Co., Inc. and operated as
a manufacturer's representative for technology products and components. In 1987,
the Company was renamed Datalink Corporation to reflect the Company's transition
to a distributor of data storage products. Beginning with the hiring of Greg R.
Meland in 1991, the current management team recognized that rapid and complex
changes in data storage technology would lead businesses and organizations
increasingly to seek external expertise to address their data storage needs.
Accordingly, the Company made the strategic decision to focus on providing its
customers with complete data storage solutions encompassing the best technology
available. By developing engineering expertise and high quality customer service
and support, Datalink became a leader in providing data storage solutions.
 
     Datalink's customers include end-users, VARs and OEMs. The Company works
closely with end-users and VARs to assess their informational storage and
retrieval requirements and to design, integrate, install, and support
information storage solutions incorporating the best hardware and software
products on the market. For OEM customers, the Company's team of design and
application engineers custom design storage subsystems, which are integrated
into the OEM's own products. In general, the Company realizes higher gross
margins on net sales to end-users and OEMs based on the high value-added nature
of such sales.
 
     The Company realizes substantial repeat business from its existing
customers. During 1997, 1996 and 1995, sales to existing customers represented
79.9%, 77.7% and 82.6%, respectively, of net sales. Management believes that
this repeat business is attributable to the Company's high level of technical
expertise and customer service and support.
 
     Datalink sells its products through its direct sales force located in
Minneapolis and 11 field offices. The Company has continued to grow its sales
force and open new sales office locations in anticipation of increased demand
for the Company's products and services. The Company selects new sales office
locations based upon perceived demand for the Company's products and services.
Datalink has experienced, and expects to continue to experience, an increase in
sales and marketing expenses disproportionate to the increase of net sales in
connection with the opening of new sales offices. This is due primarily to the
lead time (six months or longer) generally associated with generating business
in the new territory.
 
     As an independent storage solutions provider, Datalink updates its product
offerings to match advancements by its suppliers of hardware and software
technology. Although the Company often has advance knowledge of forthcoming
product releases because of its close working relationship with its suppliers,
the impact of these advancements on the Company's results of operations are
often difficult to predict. The Company's customers may delay purchases upon
learning of actual or rumored new product introductions. In addition, changes in
technology may significantly affect the pricing or profitability of products.

COMPARISON OF THREE MONTHS ENDED MARCH 31, 1998 AND 1997
 
     Net Sales. Net sales include sales of products and software integrated for
end-user and VAR customers, products assembled by the Company for OEM customers
and revenues from billable installation, repair and maintenance services.
Datalink recognizes product revenues as its products are shipped or following
customer acceptance for products under evaluation. Net sales increased $1.3
million or 8.7% to $16.6 million for the three months ended March 31, 1998, from
$15.3 million for the comparable period in 1997. The increase primarily resulted
from an increase in volume, principally attributable to increases in sales of
products to end-user customers and revenues from maintenance contracts partially
offset by decreases in sales to VAR and OEM customers.
 
     Gross Profit. Cost of sales consists primarily of the cost of components
purchased from suppliers. Gross profit as a percentage of net sales increased to
23.4% for the three months ended March 31, 1998, from 21.3% for the comparable
period in 1997. This increase was principally attributable to the Company's
increasing sales of large storage systems to end-user customers.
 
     Sales and Marketing. Sales and marketing expenses include wages and
commissions paid to the Company's sales and marketing personnel, travel and
entertainment costs and advertising, promotion and trade show expenses. Sales
and marketing expense increased $190,000 or 15.4% to $1.4 million, or 8.6% of
net sales, for the three months ended March 31, 1998, from $1.2 million, or 8.1%
of net sales, for the comparable period in 1997. This increase was primarily
attributable to additional sales commission associated with sales growth, the
hiring of new marketing personnel and increased advertising costs.
 
     General and Administrative. General and administrative expenses include
wages for administrative personnel, profit sharing contributions, professional
fees, communication expenses and rent and related facility expenses. General and
administrative expenses increased $267,000 or 38.4% to $961,000, or 5.8% of net
sales, for the three months ended March 31, 1998, as compared to $695,000, or
4.6% of net sales, for the first quarter of 1997. This increase was principally
attributable to increases in administrative personnel and related expenses and
professional fees.
 
     Engineering. Engineering expenses include employee wages, travel and
training expenses for the Company's professional engineers and technicians and
professional fees to obtain various independent laboratory certifications of
storage subsystems designed by the Company for OEM customers. Engineering
expenses increased $64,000 or 25.3% to $315,000, or 1.9% of net sales, for the
three months ended March 31,
 
                                       18
<PAGE>   22
 
1998, from $251,000, or 1.6% of net sales, for the comparable period in 1997.
This increase was primarily attributable to the addition of new engineering
personnel and increased travel expenses.
 
     Operating Income. Operating income increased $96,000 or 8.9% to $1.2
million, or 7.1% of net sales, for the three months ended March 31, 1998, from
$1.1 million, or 7.0% of net sales, for the comparable period in 1997. The
increase as a percentage of net sales was principally attributable to the
increase in gross profit without a commensurate increase in operating expenses.
 
COMPARISON OF YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
 
     Net Sales. Net sales increased 30.4% to $71.3 million in 1997, increased
43.6% to $54.7 million in 1996 and increased 17.7% to $38.0 million in 1995.
These increases were principally attributable to an increase in sales of large
RAID and tape backup storage systems to end-user customers.
 
     Gross Profit. Gross profit as a percentage of net sales increased to 21.8%
in 1997 from 21.6% in 1996 and 20.2% in 1995. These increases were primarily due
to the Company's increasing sales of large storage systems to end-user
customers.
 
     Sales and Marketing. Sales and marketing expenses increased 43.9% to $5.2
million in 1997 and increased 45.0% to $3.6 million in 1996. Sales and marketing
expenses were $2.5 million in 1995. As a percentage of net sales, sales and
marketing expenses were 7.3% in 1997, 6.6% in 1996 and 6.5% in 1995. The
increases as a percentage of net sales over these years were principally
attributable to an increase in commissions paid to the Company's sales
representatives on large storage system sales to end-user customers and to the
hiring of new sales representatives in anticipation of future growth.
 
     General and Administrative. General and administrative expenses increased
26.4% to $3.0 million in 1997 compared to 1996 and increased 12.5% to $2.4
million in 1996 compared to $2.1 million in 1995. As a percentage of net sales,
general and administrative expenses were 4.2% in 1997, 4.4% in 1996 and 5.6% in
1995. The dollar increase in general and administrative expenses was primarily
attributable to increases in administrative personnel and related expenses. The
decrease as a percentage of net sales over such periods was principally
attributable to the significant increase in net sales over these periods.
 
     Engineering. Engineering expenses increased 46.4% to $926,000 in 1997 as
compared to 1996 and increased 35.6% to $633,000 in 1996 as compared to $467,000
in 1995. Engineering expenses as a percentage of net sales were 1.3% in 1997 and
1.2% in both 1996 and 1995. The dollar increase over these years was primarily
attributable to the addition of new engineering personnel and increased travel
expenses.
 
     Operating Income. Operating income increased 24.2% to $6.4 million in 1997
as compared to 1996 and 96.8% to $5.2 million in 1996 as compared to $2.6
million in 1995. As a percentage of net sales, operating income was 9.0% in
1997, 9.4% in 1996 and 6.9% in 1995. The decrease in operating income as a
percentage of net sales in 1997 was principally attributable to the investment
in sales and marketing expenses in anticipation of future sales growth. The
increase in operating income as a percentage of net sales in 1996 was
principally attributable to the significant increase in net sales.

(1) Pro forma net income has been computed as if the Company was a C corporation
    and had been subject to federal and state income taxes during all of the
    periods presented. See Notes 2 and 3 of the Notes to the Company's Financial
    Statements.
 
     The Company has experienced and expects to continue to experience quarterly
variations in its net sales as a result of a number of factors including, among
other things, the length of the sales cycle with end-user customers for large
storage system evaluations and purchases, the significant lead time in designing
storage subsystems for OEM customers, new product introductions by suppliers and
the market acceptance thereof, delays in product shipments or other quality
control difficulties, the ability of Datalink to integrate any acquired
businesses, product returns, trends in the Open Systems storage industry in
general, the geographic and industry specific market in which Datalink is
presently active, or may be in the future, and the opening of new field sales
offices. Net sales also tend to be lower in the summer months and higher in the
quarter ending December 31 reflecting the timing of purchase decisions by the
Company's customers.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company has historically financed its operations and capital
requirements through cash flows generated from operations and supplemental bank
borrowings. Working capital was $6.7 million, $6.8 million and $5.3 million at
March 31, 1998 and December 31, 1997 and 1996, respectively. The increase was
primarily attributable to an increase in cash and net accounts receivable offset
by a decrease in inventories and an increase in borrowings under the Credit
Agreement.
 
     Cash provided by operating activities for 1997, 1996 and 1995 was $4.6
million, $2.5 million and $2.3 million, respectively, reflecting the Company's
increasing sales and net income. Cash used in investing activities during 1997,
1996 and 1995 was $766,000, $337,000 and $286,000, respectively. These uses
reflected expenditures for computer and office equipment and improvements to
support increasing sales volumes, including the opening of new field sales
offices. Cash used in financing activities in 1997, 1996 and 1995 was $2.8
million, $2.0 million and $2.2 million, respectively. These uses of cash relate
primarily to net repayments of borrowings under the Company's Credit Agreement
and to dividends paid to the stockholders. These dividends totaled $4.0 million,
$1.9 million and $1.3 million in 1997, 1996 and 1995, respectively, and were
distributed to the stockholders primarily to provide liquidity to pay their
income tax liabilities resulting from the Company's S corporation taxable
income.
 
     At March 31, 1998, the Company's borrowings consisted of $1.1 million owed
under the Credit Agreement. The Credit Agreement permits the Company to borrow
up to $10.0 million on a revolving basis with borrowings limited by eligible
accounts receivable and inventories. Upon the closing of this offering, the
borrowings under the Credit Agreement will bear interest at the bank's reference
rate; however, the Company may periodically borrow funds under the Credit
Agreement at LIBOR plus 1.95%. The Credit Agreement
 
                                       20
<PAGE>   24
 
terminates on May 31, 2000. Borrowings under the Credit Agreement are
collateralized by the Company's cash, accounts receivable, intangibles,
inventories and equipment. The Company intends to use a portion of the net
proceeds of this offering to repay all borrowings under the Credit Agreement.
 
     The Company plans to use a portion of the net proceeds of this offering to
fund the final S corporation distribution to the current stockholders. This
distribution will constitute all of the previously taxed, but undistributed, S
corporation earnings. As of March 31, 1998, such earnings were approximately
$8.2 million. The actual amount of the distribution will be adjusted to reflect
the taxable income and any stockholder distributions from April 1, 1998 through
the termination of the S corporation status upon the closing of this offering.
 
     The Company has entered into a nonbinding letter of intent to acquire DCSI.
Under terms of the letter of intent, the Company would acquire all of DCSI's
capital stock in exchange for $2 million of cash and 200,000 shares of the
Company's Common Stock, subject to adjustment, and the Company would pay an
aggregate amount of $500,000 of cash to certain employees of DCSI in connection
with noncompetition agreements.
 
     The Company believes that funds generated from operations, together with
the net proceeds of this offering, available credit under its Credit Agreement
and trade credit from suppliers will be sufficient to finance its current
operations and planned capital expenditure requirements for at least the next
twelve months.
 
     Inflation. The Company does not believe that inflation has had a material
effect on its results of operations in recent years; however, there can be no
assurance that the Company's business will not be adversely affected by
inflation in the future.
 
     Year 2000 Compliance. The Company has completed an assessment of its
internal systems and believes that these systems will not experience any Year
2000 problems. The Company is in the process of assessing the Year 2000
compliance of its supplier and customer systems and supplier products installed
at customer sites. If the Company's suppliers or customers fail to complete any
required Year 2000 remediation of their computer systems or product offerings,
the Company could suffer delays in product delivery or could experience delays
in customer payments. In addition, if any products or components sold by the
Company to its customers were to fail, the Company could be liable to its
customers for damages and costs to the extent that the Company's suppliers do
not cover such liabilities. Any such Year 2000 failures could have a material
adverse effect on the Company's financial condition, results of operations or
liquidity.
 
     Recently Issued Accounting Standards. Effective at year-end 1998, the
Company will adopt Statement of Financial Accounting Standard No. 131 (SFAS No.
131), "Disclosure About Segments of an Enterprise and Related Information,"
which requires disclosure of segment data in a manner consistent with that used
by an enterprise for internal management reporting and decision making. The
Company believes that it will report its operations as a single segment under
SFAS No. 131.

INDUSTRY OVERVIEW
 
     The reliable access to and management of data is increasingly critical and
represents a key competitive advantage to business, government, educational and
nonprofit organizations. In recent years, organizations ranging from small
businesses and nonprofit entities to large, multinational enterprises have
increased their use of computers for collecting, analyzing and distributing
information to improve productivity. Historically, most computing environments
were controlled by expensive, host-based mainframes and minicomputers having
proprietary operating systems ("Closed Systems"). This limited the ability of
these computers to communicate outside their own environment. The selection of
these Closed Systems was largely based upon the processing power generated by
the computer's central processing unit ("CPU"). This CPU centered architecture
was considered the most important aspect of designing an organization's
management information system ("MIS"). In a Closed Systems computing
environment, end-user applications were limited by the hardware and operating
system architectures offered by the manufacturer. As the number of applications
grew and the need to distribute computing power directly to users became
increasingly important, organizational demand for an appropriate systems
solution dictated operating architectures linking multiple application, file,
database and communications servers to networked computers ("Open Systems").
 
     The increased use of Open Systems hardware and software computing
environments creates the need for flexible and comprehensive data storage
solutions capable of serving multiple and evolving computer platforms.
Consequently, organizations are changing the way they manage data from a CPU
centered view to a new information centered model that requires the sharing,
management and protection of mission critical information across the enterprise.
Open Systems architecture permits organizations to utilize hardware and software
products and components available from various suppliers.
 
     In addition to the challenges presented by the Open Systems computing
environment, computer processing power has continued to increase at a rapid rate
with the ongoing introduction of new and more powerful CPUs. Application
software developers are taking advantage of CPU advancements by introducing
powerful, easier to use, graphically oriented, memory intensive software
packages. These software applications have resulted in the automation of an
increasing number of mission-critical business applications, including on-line
transaction processing, the Internet, intranets, pre-press, multimedia, imaging
and data warehousing. This automation expands the need for on-line storage,
uninterrupted access to data and fail-safe methods to backup and archive such
data. Although substantial, the increase in storage device performance has
lagged the increase in processing power, creating an input/output performance
gap that continues to widen. This performance gap has increased the need for
high performance storage systems that accelerate on-line access to stored data
while providing continuous protection of this data.
 
     Although demand for complex storage solutions is increasing, corporate
downsizing has led organizations to reduce their in-house MIS staffs.
Accordingly, organizations rely on external providers to research, design,
implement and support information storage solutions that incorporate the best
hardware and software technologies available and are compatible with
organizations' often large and complex distributed computer networks and Open
Systems operating system architectures. At the same time, reduced profit margins
have led suppliers to downsize their sales and marketing forces. As a result,
both customers and suppliers increasingly seek independent solutions providers,
such as Datalink, with knowledge and experience in Open Systems data storage.
According to Dataquest, Inc., an independent market research firm, the worldwide
RAID storage market for UNIX and Windows NT operating platforms was
approximately $12.8 billion in
                                       22
<PAGE>   26
 
1997 and is expected to grow at an annual compound rate of 24% to approximately
$37.0 billion by 2002. According to SRC, an independent market research firm,
the worldwide market for tape automation backup storage products was
approximately $1.6 billion in 1996 and is expected to grow at an annual compound
rate of 18% to approximately $4.4 billion by 2002. According to SRC, the
worldwide storage management software market was approximately $1.4 billion in
1997 and is expected to grow at an annual compound rate of 38% to approximately
$3.7 billion by 2000.

PRODUCTS
 
     Datalink continually updates its product offerings to match advancements by
its suppliers in storage technology. Datalink's creative engineering and sales
teams design solutions that incorporate hardware, software and interface
products selected in response to each customer's specific requirements. These
products include the following:
 
     Hardware Products. Datalink selects from among a variety of storage
products and components sold by leading suppliers that offer differing
performance characteristics and costs. These storage products and components
include magnetic (hard) disk, magnetic tape and optical disk storage
technologies.
 
          HARD DISK TECHNOLOGIES. Hard disk storage is a traditional, but
     relatively expensive, on-line method to store and access large amounts of
     information. Several hard disks can be combined to create a scaleable
     storage system or a RAID storage system. RAID systems allocate data across
     multiple hard disk drives and allow the server to access these drives
     simultaneously, thus increasing system storage and input/output
     performance. RAID algorithms allow lost data on any drive to be recreated,
     thus ensuring the integrity of RAID-protected data even in the event of a
     disk drive failure. In addition, RAID systems can incorporate redundant
     power, cooling and processing components for additional fault tolerance.
     System administrators normally consider magnetic or hard disks, whether
     free-standing or integrated in RAID systems, to be at the top of the
     storage class in terms of performance because of their fast access times
     (in milliseconds) and fast transfer rates (5-16 MB per second). The
     potential loss of data contained on magnetic or hard disks due to human
     error or catastrophic failure necessitates the use of a backup storage
     system to protect the stored information.
 
          MAGNETIC TAPE TECHNOLOGIES. Magnetic tape storage technologies are
     typically integrated into environments that require backing up large
     amounts of information to protect from accidental data loss and facilitate
     disaster recovery. Due to its high capacity and relatively lower cost,
     magnetic tape storage is also effective for near on-line, archive and
     hierarchical storage management ("HSM") activities. A variety of tape drive
     technologies are available, including those utilizing digital linear tape,
     advanced intelligent tape ("AIT"), 8 mm tape, 4 mm digital data storage
     ("DDS") and high performance helical scan technologies. Magnetic tape
     autoloaders and libraries integrate multiple tape drives and media
     cartridges with robotics to increase capacity and automation.
 
          OPTICAL DISK TECHNOLOGIES. Although slower than magnetic disks in
     terms of access and transfer speeds, optical disk technologies are a
     cost-effective solution for near on-line and archive storage. Optical disk
     technologies include magneto-optical ("MO"), write-once-read-many ("WORM")
     and compact disk -- read only memory ("CD-ROM") products. Capacities range
     from 650 megabytes (CD-ROM) to 2.6 GB (MO optical disk) per cartridge. MO
     optical disk capacities are expected to increase to 5.2 GB
 
                                       25
<PAGE>   29
 
     in the near future. A developing optical technology, digital versatile disk
     ("DVD"), is expected to offer approximately 7.2 times the storage capacity
     of a single CD-ROM. Similar to magnetic tape systems, multiple optical
     disks can be combined in a jukebox to permit automated access and increased
     capacity.
 
     Software Products. Datalink integrates software management tools into its
customer solutions from leading storage software developers. The latest advances
include enterprise storage solutions for backup and recovery, HSM, archive,
management and configuration, high availability and media management
capabilities. These tools enable system administrators to allocate the use of
storage technologies among user groups or tasks, centrally manage distributed
storage technologies, retrieve, transfer and backup data from and between
several devices, perform "hot" database backups during business hours, run
management reports and establish standard policies. Software advancements also
enable these tools to integrate into centralized management frameworks. These
expanded management capabilities, as well as the ability to diagnose system
failures, increasingly will become important as Fibre Channel interfaces permit
the locating of backup storage devices in secure, remote facilities.
 
     Interface Products. Systems administrators traditionally have connected
storage technologies directly to servers utilizing "point-to-point" connections
via the Small Computer Systems Interface ("SCSI"), and its successor, Ultra
SCSI. Because of distance limitations and limited bandwidth, SCSI-based
connections do not allow storage technologies to be easily shared with other
servers. With the innovation of Fibre Channel, a new serial interface, networks
can transfer data to disk and RAID storage subsystems at higher speeds, over
greatly increased distances and among a greater number of server and other
device connections than through the use of SCSI or Ultra SCSI interfaces.
Datalink currently deploys Fibre Channel interfaces with high-end, hard disk and
RAID storage systems and expects to integrate Fibre Channel interfaces with
other storage technologies in the future.
 
     As Open Systems information storage needs continue to grow, industry
experts predict the rapid deployment of storage area networks ("SANs") which
will link physically separated storage and backup technologies to the other
servers via a dedicated, high-speed network. The Company believes that SANs will
be enabled principally by Fibre Channel technology and by "clustering" software.
Fibre Channel allows high speed connections (100-200 MB per second) between and
among a greater number of hosts and storage technologies on the SAN, while
clustering software allows for the interconnection of multiple hosts to multiple
storage devices. The Company expects that SANs will enable organizations to
implement scaleable storage and backup solutions that are faster, easier to
manage and protect, offer a higher degree of data availability and can be shared
by a greater multiple of servers than current distributed Open Systems storage
systems.

INTEGRATION AND ASSEMBLY OPERATIONS
 
     Datalink assembles and integrates hardware and software products and
components acquired from the Company's various suppliers. The Company designs
customized enclosures for most OEM products. The assembled units are then
subjected to a system level test to ensure performance to specifications in the
anticipated end-user computing environment. The Company's integration and
assembly operations are also ISO 9001 registered. In accordance with these
standards, the Company has designed its integration and assembly operations with
similar quality procedures to those of its hardware suppliers. Datalink's close
working relationship with its suppliers generally enables the Company to
exchange critical information and implement joint corrective action programs to
ensure the quality of its finished products, to reduce costs and the investment
in inventory and to access critical products and components for large or
unanticipated orders when required. The Company believes that its current
facilities are adequate to meet its integration and assembly needs in the
foreseeable future.
 
ISO 9001 QUALITY SYSTEM
 
     In May 1996, Datalink completed an approximately three-year process of
obtaining an ISO 9001 Certificate of Registration from KPMG Quality Registrar
for its quality system described under the American National Standards
Institute. This internationally recognized endorsement of ongoing quality
management is designed to assure consistent quality products and services. The
Company believes its ISO 9001 registration represents a substantial competitive
advantage to Datalink in attracting and retaining business.
 
     Datalink employs ISO 9001 standards of operation for its design,
development, integration and assembly, installation and service processes. These
quality initiatives streamline the quality assurance programs and implementation
procedures for the Company's customers. Datalink's quality assurance team
constantly monitors the Company's processes and procedures, identifies areas for
improvement and efficiently implements corrective and preventive actions.
Suppliers to the Company are required to be ISO 9001 registered or otherwise
meet Datalink's rigid supplier qualification standards.
 
SUPPLIER RELATIONSHIPS
 
     As an independent solutions provider, Datalink continually evaluates and
tests new and emerging technologies from other companies to ensure that the
Company's solutions incorporate state-of-the-art, high-end, cost-effective Open
Systems technologies. This enables Datalink to maintain its technological
leadership in Open Systems storage solutions, to identify new and innovative
products and applications and to maintain confidence among the Company's
customers and suppliers in the Company's expertise.
 
     Datalink has strong, established relationships with the major information
storage hardware and software suppliers. The Company's expertise in Open System
environments, including UNIX, Windows NT and Novell NetWare, and in-depth
knowledge of all major hardware platforms, including Digital, Hewlett-Packard,
IBM, Silicon Graphics and Sun, has earned Datalink preferred status with its
principal suppliers. This enables the Company to often participate in these
suppliers' new product development, evaluation, introduction, marketing and
quality control programs. These collaborations enable the Company to identify
and market innovative new hardware and software products, exchange critical
information and implement joint corrective action programs in order to maximize
quality. In addition, the Company's close working relationships with its
principal suppliers fosters substantial cross-marketing opportunities.
 
COMPETITION
 
     The market for Open Systems storage is intensely competitive. Datalink
competes primarily with traditional suppliers of computer systems such as
Compaq, Digital, Hewlett-Packard, IBM, Silicon Graphics and Sun, which market
storage systems as well as other computer products. The Company also competes
                                       28
<PAGE>   32
 
against independent storage system suppliers to the high-end Open Systems
market, including Box Hill Systems Corp., EMC Corporation, MTI Technology
Corporation and numerous VARs, resellers, distributors and consultants. In
addition, the Company's customers and prospective customers may elect to develop
in-house storage systems expertise.
 
     Many of the Company's current and potential competitors have significantly
greater financial, technical, marketing, purchasing and other resources than the
Company, and as a result, may be able to respond more quickly to new or emerging
technologies and changes in customer requirements, to devote greater resources
to the development, promotion and sale of products than the Company or to
deliver competitive products at a lower end-user price. Some of Datalink's
competitors include its suppliers, who may dedicate or acquire greater sales and
marketing resources in the future to provide Open Systems storage solutions than
at present and could terminate their relationships with the Company. Other
suppliers may also enter the market and compete with the Company. Datalink
expects competition will increase as a result of industry consolidation. Current
and potential competitors have established or may establish cooperative
relationships among themselves or with third parties to increase the ability of
their products to address the needs of the Company's prospective customers.
Accordingly, it is possible that new competitors or alliances among competitors
may emerge and rapidly acquire significant market share. Increased competition
may result in price reductions, reduced operating margins and loss of market
share, any of which could have a material adverse effect on the Company's
business, operating results or financial condition. See "Risk Factors --
Competition."
 
EMPLOYEES
 
     As of March 31, 1998, Datalink had a total of 77 full-time employees, of
whom 20 were engaged in engineering, technical support, customer service and
integration and assembly operations, 38 were engaged in sales and marketing and
19 were engaged in general management and administration. The Company's future
performance depends in significant part upon the continued service of its key
technical and senior management personnel. None of the Company's employees are
unionized or subject to a collective bargaining agreement. The Company has
experienced no work stoppages and believes that its employee relations are good.
 
FACILITIES
 
     Datalink's principal engineering operations and its integration, assembly
and customer service operations are located at the Company's 26,653 square foot,
leased executive and administrative facility in Minneapolis, Minnesota. The
lease, which expires in December 1999, provides the Company with certain rights
to take additional space in the building. The Company's landlord is a
partnership whose partners consist of Datalink's current stockholders. See
"Certain Transactions." Datalink believes that the facility is adequate for its
needs in the foreseeable future. The Company also leases certain remote
facilities for its field sales and engineering personnel. Datalink believes that
these facilities are adequate for its needs in the foreseeable future and that
it will be able to locate suitable additional facilities as the Company expands
geographically.

the results and scope of their auditing engagement and certain other matters
relating to their services to the Company.
 
DIRECTOR COMPENSATION
 
     Contemporaneously with the closing of this offering, the Company will grant
to each of Mr. Price, Mr. Ousley, Ms. Loftus and Mr. Lidsky stock options to
purchase 6,000 shares of the Company's Common Stock at an exercise price equal
to the initial public offering price per share on the cover page of this
Prospectus. These options will vest on the date of the closing of this offering
and will expire ten years from the date of grant. Additionally, commencing with
the Company's 1999 annual stockholders' meeting, the Company intends to
compensate each director who is neither an employee nor an affiliate of Datalink
with an annual grant of options to purchase 3,000 shares of the Company's Common
Stock. These options will be exercisable commencing one year after the date of
grant; provided, however, that if a director fails to serve until the annual
stockholder's meeting immediately succeeding the grant of the options, the
number of shares of Common Stock that may be purchased by such director shall be
pro rated based upon the length of time such departing director actually served.
The options will be exercisable at the fair market value of the Company's Common
stock on the date of grant and expire ten years after the date of grant. All
directors will be reimbursed for expenses incurred in connection with attendance
at Board and committee meetings.
 
INDEMNIFICATION AGREEMENTS
 
     The Company has entered into an agreement with each director providing for
indemnification to the fullest extent permitted under Minnesota law against
liability for damages and expenses, including attorneys' fees, arising out of
threatened, pending or completed legal actions, suits or proceedings by reason
of the fact that such person is or was a director, officer or employee of the
Company. The agreement will permit the director to demand certain advances
against, or the creation of a trust for, expenses to be incurred in defending
any covered claim. Insofar as the indemnification agreement may cover
liabilities arising under the Securities Act, the Company has been advised that
in the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable.

STOCK INCENTIVE PLANS
 
     The Company's Employee Stock Purchase Plan (the "Purchase Plan") and the
Incentive Compensation Plan (the "Incentive Compensation Plan" and with the
Purchase Plan collectively referred to as the "Stock Incentive Plans") were
adopted by the Company and its stockholders in June 1998. The Stock Incentive
Plans provide the employees of the Company an opportunity to invest in shares of
Common Stock. In some instances, these purchases may be on terms more favorable
than would otherwise be available. The Company believes that, by aligning the
interests of the participants and the Company, the implementation of the Stock
Incentive Plans will strengthen the commitment of the participants to the
Company's success.
 
     Purchase Plan. The Company has reserved 250,000 shares of Common Stock for
issuance under the Purchase Plan, subject to equitable adjustments as the
Compensation Committee (as defined above) may deem necessary to prevent dilution
or the enlargement of rights of participants as a result of, among other things,
changes in the Company's capitalization or corporate structure. The Purchase
Plan will be administered by the Compensation Committee and is intended to
qualify under Section 423 of the Code. Pursuant to the Purchase Plan, each
eligible employee, as of the start of any purchase period, will be granted an
option to purchase a designated number of shares of Common Stock. The purchase
price of shares of Common Stock to participating employees will be 85% of the
lower of the fair market value of the Company's Common Stock on the first and
last trading days of the relevant purchase period. Payments for shares purchased
under the
 
                                       32
<PAGE>   36
 
Purchase Plan will be made in the time and manner specified by the Compensation
Committee. An employee may terminate his or her participation in the Purchase
Plan by giving a notice of withdrawal to the Company sufficiently in advance of
the last trading day of the relevant purchase period, and all funds contributed
to date will be refunded to such employee.
 
     Employees are eligible to participate in the Purchase Plan if they (i) are
customarily employed by the Company for more than twenty hours per week and five
months in any calendar year and (ii) will not, immediately upon purchasing
shares under the Purchase Plan, own directly or indirectly 5% or more of the
total combined voting power of all outstanding shares of all classes of stock of
the Company. Notwithstanding the foregoing, no employee may purchase shares
under the Purchase Plan (or any other plan of the Company intended to qualify
under Section 423 of the Code) in any calendar year with an aggregate fair
market value (as determined on the first day of the relevant purchase period) in
excess of the lesser of 10% of such employee's salary or the maximum value
allowed under the Code. Participation in the Purchase Plan ends automatically
upon termination of employment with the Company. Rights granted under the
Purchase Plan are not transferable other than by will or the laws of descent and
distribution.
 
     The Board may at any time amend or terminate the Purchase Plan so long as
such amendment or termination does not result in the failure of rights issued
under the Purchase Plan to meet the requirements for employee stock purchase
plans as defined in Section 423 of the Code.
 
     Incentive Compensation Plan. The Company has reserved 950,000 shares of
Common Stock for issuance under the Incentive Compensation Plan. The Incentive
Compensation Plan will be administered by the Compensation Committee. The
Compensation Committee will have full authority, subject to the provisions of
the Incentive Compensation Plan, to determine, among other things, the persons
to whom awards under the Incentive Compensation Plan ("Awards") will be made,
the exercise price, vesting, size and type of such Awards, and the specific
performance goals, restrictions on transfer and circumstances for forfeiture
applicable to Awards.
 
     Awards may be made to employees and non-employee directors of the Company
or affiliates and other individuals designated by the Compensation Committee. A
variety of Awards may be granted under the Incentive Compensation Plan including
stock options, stock appreciation rights ("SARs"), restricted stock, performance
shares, performance units, cash-based awards, phantom shares and other
share-based awards as the Compensation Committee may determine. Stock options
granted under the Incentive Compensation Plan may be either incentive stock
options intended to qualify under Section 422 of the Code or nonqualified stock
options not so intended.
 
     Provisions regarding the extent to which a participant shall have the right
to exercise and/or receive payment for any Award following termination of the
participant's employment, directorship or other relationship with the Company
shall be determined at the discretion of the Board. In the event of a "change of
control" (as defined in the Incentive Compensation Plan), (i) all outstanding
options and SARs granted under the Incentive Compensation Plan will become
immediately exercisable and remain exercisable throughout their entire term,
(ii) any performance-based conditions imposed with respect to outstanding Awards
shall be deemed to be fully earned and a pro rata portion of each such
outstanding Award granted for all outstanding performance periods shall become
payable in shares of Common Stock, in the case of Awards denominated in shares
of Common Stock, and in cash, in the case of Awards denominated in cash, with
the remainder of such Award being canceled for no value and (iii) all
restrictions imposed on restricted stock that are not performance-based shall
lapse. The Board may make equitable adjustments, including with respect to the
number and kind of shares issuable under, and the exercise price relating to,
Awards as the Board may deem necessary to prevent dilution or accretion of the
rights of participants under the Incentive Compensation Plan as a result of
changes in the Company's corporate structure or capitalization.
 
     Awards under the Incentive Compensation Plan are not transferable other
than by will or by the laws of descent and distribution, unless otherwise
provided by the Board. The Board may amend or terminate the Incentive
Compensation Plan except that no amendment shall be made without stockholder
approval if such approval is necessary to comply with any applicable regulatory
or tax requirements. Notwithstanding the foregoing, in no event may an Award be
granted under the Incentive Compensation Plan after June 2008.
                                       33
<PAGE>   37
 
     Option Grants. Contemporaneously with the closing of this offering, the
Company will grant certain directors and employees of the Company stock options
to purchase an aggregate of 214,750 shares of Common Stock under the Incentive
Compensation Plan. These options will be exercisable at an exercise price equal
to the initial public offering price shown on the cover page of this Prospectus.
The options granted to the directors will vest on the date of the closing of
this offering. The options granted to the employees will vest over a five-year
period, with 20% of the options vesting each year, commencing on the first
anniversary of the closing of this offering. All of these options will expire
ten years from the date of grant.
 
THE 401(K) PLAN
 
     The Company has a salary deferral plan, the Datalink Corporation 401(k)
Plan (the "401(k) Plan"), which is intended to qualify under Sections 401(a) and
401(k) of the Code. Company employees are eligible to participate in the 401(k)
Plan beginning on the first day of the quarter immediately succeeding the
commencement of their employment with the Company. Participants may make
elective salary reduction contributions to the 401(k) Plan up to a maximum of
10% of their eligible annual compensation, subject to a dollar limit established
by law (which limit was $9,500 in 1997). Pursuant to the terms of the 401(k)
Plan, the Company is required to match 50% of the participants contribution up
to the first 6% of the participants' eligible compensation. The cost of the
Company's contributions to the 401(k) Plan for the years ended December 31,
1995, 1996 and 1997, and for the three months ended March 31, 1997 and 1998 were
approximately $79,000, $97,000, $126,000, $38,000 and $50,000, respectively. In
addition, at the discretion of the Board of Directors, the Company may
contribute to a profit sharing portion of the 401(k) Plan to the extent
permitted by the Code. The cost of contributions to the profit sharing portion
of the 401(k) Plan for the years ended December 31, 1995, 1996 and 1997 were
approximately $91,000, $157,000 and $164,000, respectively. The Company did not
make any profit sharing contributions to the 401(k) Plan for the three months
ended March 31, 1997 and 1998.
 
     Participants are fully vested at all times in the amounts they contribute
to the 401(k) Plan and are always 100% vested upon early or normal retirement.
Participants vest at a rate of 20% per year and are fully vested in the
Company's matching and discretionary profit sharing contributions after five
years. Benefits under the 401(k) Plan generally are distributable after the age
of 59 1/2 or become payable upon separation from service, retirement, death or
disability.
 
                              CERTAIN TRANSACTIONS
 
     In February 1997, the Company entered into a lease agreement for its
principal executive offices with Edina Southwest Partners, a Minnesota general
partnership ("Edina Partners"). In June 1997, Edina Partners sold the property
containing the Company's principal executive offices (the "Property") to 7423
Washington Avenue L.L.P., a Minnesota limited liability partnership ("Washington
Avenue L.L.P."), of which the Company's six current stockholders own, in the
aggregate, 100% of the units of interest. Contemporaneously with the purchase of
the Property, Washington Avenue L.L.P. executed promissory notes in favor of
Norwest Bank Minnesota, N.A. (the "Norwest Note") and Stanley I. Clothier,
Trustee of the Stanley I. Clothier Revocable Trust (the "Clothier Note"). The
Company has agreed to guarantee the payments under these notes.
Contemporaneously with the closing of this offering, the Company's obligations
to guarantee these notes will terminate. As of March 31, 1998, the balances on
the Norwest Note and Clothier Note were approximately $956,000 and $1.4 million,
respectively.
 
     Additionally, the Washington Avenue L.L.P. agreement provides that in the
event that gross revenues of the partnership are insufficient to pay the
operating costs of the Property and other necessary business or administrative
expenses, the partners, individually and as current stockholders of Datalink,
agree to take any and all steps necessary to cause the Company to increase its
lease payments on the space it is occupying or to lease additional space in the
Property in order to fund such deficit. Contemporaneously with the closing of
this offering, the Company's obligations to fund such deficit will terminate.
The rent paid by the Company to Washington Avenue L.L.P. in 1997 and the first
quarter of 1998 was approximately $197,000 and $51,000, respectively.
 
                                       34

     The Company entered into a deferred compensation agreement with Mr.
Clothier, a current stockholder and a former officer and director of the
Company, whereby the Company is obligated to pay Mr. Clothier (or a designated
beneficiary) $7,000 per month for 60 months beginning January 1996. Interest
expense under this agreement was $27,794, $24,942 and $6,970 for the years ended
December 31, 1996 and 1997 and for the three months ended March 31, 1998,
respectively.
 
     All material and affiliated transactions and loans made after the date of
this Prospectus will be made or entered into on terms that are no less favorable
to the Company than those that can be obtained from unaffiliated third parties,
and all such future material affiliated transactions and loans, and any
forgiveness of loans, must be approved by a majority of the independent,
non-affiliated members of the Board of Directors who do not have an interest in
the transaction.

(1) Beneficial ownership is determined in accordance with the rules of the
    Securities and Exchange Commission, and includes voting power and investment
    power with respect to shares. Shares issuable upon the exercise of
    outstanding stock options that are currently exercisable or become
    exercisable within 60 days from the date hereof, are considered outstanding
    for the purpose of calculating the percentage of Common Stock owned by such
    person and owned by a group, but not for the purpose of calculating the
    percentage of Common Stock owned by any other person.

(3) Assumes no exercise of the Underwriters' over-allotment option. The
    agreement between the Company, Mr. Clothier and the Underwriters provides
    that if the over-allotment option is exercised only in part, the
    Underwriters will first purchase shares from Mr. Clothier, up to a maximum
    amount of 70,000 shares, and then purchase any additional shares from the
    Company. If the Underwriters purchase at least 70,000 shares pursuant to
    their over-allotment option, then Mr. Clothier would beneficially hold
    275,000 shares or 2.89%. See "Underwriting."

                          DESCRIPTION OF CAPITAL STOCK
 
     The Company is authorized to issue 50,000,000 shares, par value $0.001 of
undesignated capital stock. Until otherwise designated by the Board of directors
of the Company, all authorized shares are deemed to be Common Stock. As of the
date of this offering, 6,900,000 shares of Common Stock were outstanding and
upon closing of this offering, 214,750 shares will be subject to outstanding
options granted under the Company's Incentive Compensation Plan.
 
COMMON STOCK
 
     Each share of Common Stock is entitled to one vote on all matters submitted
to a vote of the stockholders. Stockholders do not have cumulative voting
rights, the absence of which will, in effect, allow the holders of a majority of
the outstanding shares of Common Stock to elect all the directors then standing
for election. After the completion of the offering hereby and assuming no
exercise of any stock options or the Underwriters' over-allotment option, the
six current stockholders will own approximately 72.6% of the Common Stock.
 
     Subject to the rights and preferences of the Preferred Stock, if any, each
share of Common Stock has an equal and ratable right to receive dividends, when,
as and if declared by the Company's Board of Directors, out of any funds legally
available for the payment thereof. In the event of the liquidation, dissolution
or winding up of the Company, after satisfaction of amounts payable to creditors
and distribution to the holders of outstanding Preferred Stock, if any, of
amounts to which they may be preferentially entitled, holders of the Common
Stock are entitled to share ratably, on a per share basis, in the assets
available for distribution to the stockholders.
 
     Holders of Common Stock are not entitled to conversion or preemptive
rights. All outstanding shares of Common Stock are, and when issued, the shares
of Common Stock to be issued in connection with this offering, will be, fully
paid and nonassessable.
 
UNDESIGNATED STOCK
 
     The Board of Directors of the Company generally has the power to issue
shares of capital stock without stockholder approval. The Board of Directors is
authorized to establish the rights, preferences and limitations of this
undesignated stock and to divide such shares into classes, with or without
voting rights. The ability of the Board of Directors to issue additional shares
could impede or deter an unsolicited tender offer or takeover proposal regarding
the Company. Shares of undesignated stock could be issued with terms, provisions
and rights which would make more difficult and, therefore, less likely, a
takeover of the Company not approved by the Board of Directors. The rights of
the holders of the Common Stock could be adversely affected by the future
issuance of undesignated stock.
 
CERTAIN PROVISIONS OF MINNESOTA LAW
 
     The Company is governed by the provisions of Sections 302A.671 and 302A.673
of the Minnesota Business Corporation Act. These anti-takeover provisions may
eventually operate to deny stockholders the receipt of a premium for their
Common Stock. Section 302A.671 basically provides that the shares of a
corporation acquired in a "control share acquisition" have no voting rights
unless voting rights are approved by the stockholders in a prescribed manner. A
"control share acquisition" is generally defined as an acquisition of beneficial
ownership of shares that would, when added to all other shares beneficially
owned by the acquiring person, entitle the acquiring person to have voting power
of 20% or more in the election of directors. Section 302A.673 prohibits a public
corporation from engaging in a "business combination" with an "interested
shareholder" for a period of four years after the date of the transaction in
which the person became an "interested shareholder," unless the "business
combination" is approved in a prescribed manner. A "business combination"
includes mergers, asset sales and other transactions. An "interested
shareholder" is a person who is the beneficial owner of 10% or more of the
corporation's voting stock. Reference is made to the detailed terms of Sections
302A.671 and 302A.673 of the Minnesota Business Corporation Act.

TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar of the Common Stock is Norwest Bank
Minnesota, N.A.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this offering, the Company will have outstanding
9,500,000 shares of Common Stock (assuming the Underwriters' over-allotment
option is not exercised). Of these outstanding shares, the 2,600,000 shares of
Common Stock sold in this offering will be freely tradeable without restriction
under the Securities Act, except for any shares purchased by an "affiliate" of
the Company (as that term is defined in the Securities Act), which will be
subject to the resale limitations under Rule 144 adopted under the Securities
Act. The 6,900,000 shares of Common Stock held by the six current stockholders
are "restricted" securities within the meaning of Rule 144 and may not be resold
in a public distribution except in compliance with the registration requirements
of the Securities Act or pursuant to Rule 144.
 
     In general, under Rule 144 as currently in effect, an affiliate of the
Company, or person (or persons whose shares are aggregated) who has beneficially
owned restricted shares for at least one year but less than two years, will be
entitled to sell in any three-month period a number of shares that does not
exceed the greater of (i) 1% of the then outstanding shares of Common Stock
(approximately 95,000 shares immediately after the offering) or (ii) the average
weekly trading volume during the four calendar weeks immediately preceding the
date on which notice of the sale is filed with the Commission. Sales pursuant to
Rule 144 are subject to certain requirements relating to manner of sale, notice
and availability of current public information about the Company. A person (or
persons) other than an "affiliate" who has beneficially owned his or her shares
for at least two years is entitled to sell such shares pursuant to Rule 144(k)
without regard to the limitations described above. As defined in Rule 144, an
"affiliate" of an issuer is a person who directly, or indirectly through the use
of one or more intermediaries, controls, or is controlled by, or is under common
control with, such issuer. Rule 144A under the Securities Act as currently in
effect permits the immediate sale by current holders of restricted shares of all
or a portion of their shares to certain qualified institutional buyers described
in Rule 144A, subject to certain conditions.
 
     The current stockholders have agreed that they will not sell any shares of
capital stock of the Company, either publicly or privately, without the prior
consent of Needham & Company, Inc. for a period of 180 days from the date of
this Prospectus.
 
     The Company has reserved an aggregate of 950,000 shares of Common Stock for
issuance pursuant to the Incentive Compensation Plan. Upon the closing of this
offering, options to purchase a total of 214,750 shares of Common Stock will be
granted to certain employees and directors of the Company under the Incentive
Compensation Plan. Additionally, the Company has reserved an aggregate of
250,000 shares of Common Stock for issuance pursuant to the Employee Stock
Purchase Plan. As of the date of this Prospectus, no shares of Common Stock have
been issued under the Employee Stock Purchase Plan. The Company intends to file
a registration statement on Form S-8 under the Securities Act within 30 days
after the date of this Prospectus to register the shares to be issued pursuant
to the Incentive Compensation Plan and Employee Stock Purchase Plan,
respectively. Shares of Common Stock issued under these plans after the
effective date of such registration statements will be freely tradeable in the
public market, subject to the lock-up restrictions and subject in the case of
sales by affiliates to the amount, manner of sale notice and public information
requirements of Rule 144.
 
     There has been no prior market for the Common Stock and there can be no
assurance that a significant public market for the Common Stock will develop or
be sustained after the offering contemplated by this Prospectus. Sales of
substantial amounts of Common Stock in the public market could adversely affect
the market price of the Common Stock.

     The underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters will purchase all shares of Common Stock offered hereby if any of
such shares are purchased.
 
     The Company has been advised by the Representatives that the Underwriters
propose to offer the shares of Common Stock directly to the public at the
initial public offering price set forth on the cover page of this Prospectus,
and to certain securities dealers at such price less a concession of not more
than $      per share. The Underwriters may allow, and such dealers may reallow,
a concession not in excess of $      per share to certain other dealers. After
the shares of Common Stock are released for sale to the public, the offering
price and other selling terms may from time to time be varied by the
Underwriters. No change in such terms shall change the amount of proceeds to be
received by the Company as set forth on the cover page of this Prospectus.
 
     The Company and Stanley I. Clothier have granted to the Underwriters an
option, exercisable within 30 days after the date of this Prospectus, to
purchase up to 320,000 and 70,000 additional shares of Common Stock,
respectively, at the public offering price less the underwriting discounts and
commissions set forth on the cover page of this Prospectus. The agreement
between the Company, Mr. Clothier and the Underwriters provide that if the
over-allotment option is exercised only in part, the Underwriters will first
purchase shares from Mr. Clothier, up to a maximum amount of 70,000 shares, and
then purchase any additional shares from the Company. The Underwriters may
exercise such option solely to cover over-allotments, if any, made in connection
with the sale of Common Stock offered hereby. To the extent that the
Underwriters exercise the over-allotment option, each Underwriter will be
committed, subject to certain conditions, to purchase a number of additional
shares of Common Stock which is proportionate to such Underwriter's initial
commitment as set forth in the table above.
 
     The Company, its officers and directors and current stockholders have
agreed that, during the period beginning from the date of this Prospectus and
continuing to and including the date 180 days after the date of this Prospectus,
they will not offer, sell, contract to sell or otherwise dispose of any shares
of Common Stock, any securities of the Company which are substantially similar
to the shares of Common Stock or which are convertible or exchangeable for
securities which are substantially similar to the shares of Common Stock other
than pursuant to the Incentive Compensation Plan or the Purchase Plan without
the prior written consent of Needham & Company, Inc., except for the shares of
common Stock offered in connection with this offering.
 
                                       39
<PAGE>   43
 
     The Representatives have informed the Company that they do not expect sales
to accounts over which the underwriters exercise discretionary authority to
exceed 5% of the total number of shares of Common Stock offered by them.
 
     Prior to this offering, there has not been a public market for the Common
Stock of the Company. Consequently, the initial public offering price of the
Common Stock was determined by arms-length negotiation between the Company and
the Representatives of the Underwriters. Among the factors to be considered by
the Company and the Representatives in pricing the Common Stock are the results
of operations, the current financial condition and future prospects of the
Company, the experience of management, the amounts of ownership to be retained
by the current stockholders, the general condition of the economy and the
securities markets, the demand for similar securities of companies considered
comparable to the Company and other factors deemed relevant.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that the Underwriters may be required to make in respect thereof.
 
     In connection with the offering, certain Underwriters and selling group
members and their respective affiliates may engage in transactions that
stabilize, maintain or otherwise affect the market price of the Common Stock.
Such transactions may include stabilization transactions effected in accordance
with the Exchange Act pursuant to which such persons may bid for or purchase
Common Stock for the purpose of stabilizing its market price. The Underwriters
also may create a short position for the account of the Underwriters by selling
more Common Stock in connection with the offering than they are committed to
purchase from the Company, and in such case may purchase Common Stock in the
open market following completion of the offering to cover all or a portion of
such shares of Common Stock or may exercise the Underwriters' over-allotment
option referred to above. In addition, the Representatives, on behalf of the
Underwriters, may impose "penalty bids" under the contractual arrangements with
the Underwriters whereby the Representatives may reclaim from an Underwriter (or
dealers participating in the offering), for the account of the other
Underwriters, the selling concession with respect to Common Stock that is
distributed in the offering but subsequently purchased for the account of the
Underwriters in stabilization or syndicate covering transactions or otherwise.
Any of these activities may stabilize or maintain the price of the Common Stock
at a level above which might otherwise prevail in the open market. None of the
transactions described in this paragraph is required, and if they are undertaken
they may be discontinued at any time.
 
                                 LEGAL MATTERS
 
     The validity of the Common Stock offered hereby will be passed upon for the
Company by Messerli & Kramer P.A., Minneapolis, Minnesota. Certain legal matters
will be passed upon for the Underwriters by Kaplan, Strangis and Kaplan, P.A.,
Minneapolis, Minnesota.
 
                                    EXPERTS
 
     The balance sheets of Datalink Corporation as of December 31, 1996 and 1997
and the statements of operations, retained earnings (accumulated deficit) and
cash flows for each of the three years in the period ended December 31, 1997
included in this Prospectus have been included herein in reliance on the report
of Coopers & Lybrand L.L.P., independent accountants, given on the authority of
that firm as experts in accounting and auditing.
 
                             CHANGE IN ACCOUNTANTS
 
     In November 1997, the Company engaged Coopers & Lybrand L.L.P. as its
independent public accountants to audit the financial statements as of December
31, 1995, 1996 and 1997 and for each of the three years ended December 31, 1997.
The decision to change accountants was approved by the Board of Directors. The

disclaimer of opinion and was not qualified or modified as to uncertainty, audit
scope or accounting principles. There were no disagreements with the former
auditors on any matters of accounting principles or practices, financial
statement disclosure or auditing scope or procedures which, if not resolved to
the former auditor's satisfaction, would have caused them to make reference to
the subject matter in their report. Prior to retaining Coopers & Lybrand L.L.P.,
the Company did not consult with Coopers & Lybrand L.L.P. regarding the
application of accounting principles to a specified transaction, the type of
audit opinion that might be rendered on the Company's financial statements or
any other matter.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Stockholders and Board of Directors
of Datalink Corporation:
 
     We have audited the accompanying balance sheets of Datalink Corporation as
of December 31, 1996 and 1997, and the related statements of operations,
retained earnings (accumulated deficit) and cash flows for each of the three
years in the period ended December 31, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our 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 financial statements referred to above present fairly,
in all material respects, the financial position of Datalink Corporation as of
December 31, 1996 and 1997, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1997 in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
        (INFORMATION AS OF MARCH 31, 1998 AND FOR THE THREE MONTHS ENDED
                     MARCH 31, 1997 AND 1998 IS UNAUDITED)
 
1. DESCRIPTION OF BUSINESS:
 
     Datalink Corporation (the Company) analyzes, custom designs, integrates or
manufactures, installs and supports high-end Open Systems data storage solutions
for end-users, value-added resellers and original equipment manufacturers. In
May 1996, the Company became an ISO 9001 registered organization.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
     INTERIM FINANCIAL STATEMENTS
 
     The financial statements as of March 31, 1998, and for the three months
ended March 31, 1997 and 1998, are unaudited. In the opinion of management, this
financial information includes all adjustments, consisting of normal recurring
adjustments, necessary to fairly present the financial information set forth
herein. The results of operations for the three months ended March 31, 1998, are
not necessarily indicative of the results to be expected for the full year.
 
     CASH:
 
     The Company maintains its cash principally with one financial institution.
 
     INVENTORIES:
 
     Inventories, principally consisting of data storage products and
components, are valued at the lower of cost or market with cost determined on a
first-in, first-out (FIFO) method.
 
     PROPERTY AND EQUIPMENT:
 
     Property and equipment, including purchased software, are stated at cost.
Depreciation is provided by charges to operations using the straight-line method
over the estimated useful lives of the assets (ranging from 5 to 10 years).
Leasehold improvements are amortized on a straight-line basis over the shorter
of their estimated useful lives or the underlying lease term. The costs and
related accumulated depreciation and amortization on asset disposals are removed
from the accounts and any gain or loss is included in operations. Major renewals
and betterments are capitalized, while maintenance and repairs are charged to
current operations when incurred.
 
     INCOME TAXES:
 
     The Company has elected to be taxed as an S corporation under the
provisions of the Internal Revenue Code (the Code) and comparable state income
tax law. Under those provisions, the Company's income is reported on the
individual tax returns of the Company's stockholders. As such, the Company is
generally not subject to corporate income taxes. Therefore, no provision or
liability for income taxes is reflected in the financial statements for the
Company.
 
     Concurrent with the Company's proposed initial public offering (the
Offering), (see Note 11), the Company's S corporation status will terminate and
it will become subject to federal and state income taxes (see Note 3).
 
     REVENUE RECOGNITION:
 
     The Company recognizes product revenue as its products are shipped or
following customer acceptance for products under evaluation. The Company
provides an allowance for estimated returns when revenues are recognized.
Revenues and expenses related to sales of maintenance contracts fulfilled by
third parties are recognized upon execution of the contracts.

                              DATALINK CORPORATION
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     NET INCOME PER SHARE:
 
     Basic net income per share is computed using the weighted average number of
shares outstanding. The diluted net income per share includes the effect of
common stock equivalents, if any, for each period. The Company does not have any
common stock equivalents.
 
     USE OF ESTIMATES:
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
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. Actual results could differ from those estimates. The most
significant areas which require the use of management's estimates relate to the
determination of the allowance for doubtful accounts receivable and reserves for
excess and obsolete inventories.
 
     CONCENTRATION OF CREDIT RISK:
 
     The Company's customer base is diversified; however, a substantial portion
of its customers are located in the upper Midwest. The Company does not require
collateral for customer accounts receivable. The Company performs ongoing credit
evaluations of its customers' financial condition and establishes allowances for
estimated uncollectible accounts when necessary.
 
     BUSINESS SEGMENTS:
 
     Effective at year end 1998, the Company will adopt SFAS No. 131,
"Disclosure About Segments of an Enterprise and Related Information," which
requires disclosure of segment data in a manner consistent with that used by an
enterprise for internal management reporting and decision making. The Company
believes that it will report its operations as a single segment under SFAS No.
131.
 
3. PRO FORMA DATA (UNAUDITED):
 
     PRO FORMA BALANCE SHEET DATA:
 
     The pro forma balance sheet of the Company as of March 31, 1998 reflects
(i) the reclassification of common stock subject to put option to stockholders'
equity to reflect termination of the put options concurrent with the Offering
(see Note 9), (ii) a distribution payable to the stockholders of the Company of
all previously taxed, but undistributed, S corporation earnings (estimated at
$8,239,815 had the termination occurred on March 31, 1998), and (iii) a net
deferred tax asset which will be recorded by the Company upon termination of its
S corporation status as a result of the Offering (estimated at $240,000 as of
March 31, 1998).
 
     The deferred income tax asset will represent the tax effect of the
cumulative differences between the financial reporting and income tax bases of
assets and liabilities as of the termination of the S corporation status, and
will be recorded as an income tax benefit in the quarter in which the Offering
is completed. Deferred income taxes result from temporary differences between
financial reporting and income tax reporting based on enacted rates in effect
for periods in which these differences are expected to reverse. Valuation
allowances are established when necessary to reduce deferred tax assets to an
amount expected to be realized. Income tax expense is the tax payable for the
period plus the change during the period in deferred tax assets and liabilities.
 
     The actual deferred tax asset recorded will be adjusted to reflect the
effect of operations from April 1, 1998 through the actual termination of the S
corporation status. In addition, the actual amount of the
 
                                       F-8

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
distribution will be adjusted to reflect the S corporation's pro rata portion of
the Company's 1998 taxable income and any stockholder distributions from April
1, 1998 through the termination of the S corporation status.
 
     PRO FORMA STATEMENT OF OPERATIONS DATA:
 
     Concurrent with the Offering, the Company will terminate its status as an S
corporation and will be subject to federal and state income taxes. Accordingly,
for informational purposes, the accompanying statements of operations for the
year ended December 31, 1997 and the three months ended March 31, 1997 and 1998,
include a pro forma adjustment for the income taxes which would have been
recorded if the Company had been a C corporation, based on the tax laws in
effect during the period. The pro forma adjustment for income taxes does not
include a one-time income tax benefit related to the recognition of a net
deferred tax asset which will be recorded by the Company upon terminating its S
corporation status (estimated at $240,000 as of March 31, 1998).
 
     PRO FORMA NET INCOME PER SHARE:
 
     Pro forma net income per share is computed by dividing pro forma net income
by the weighted average number of shares outstanding (6,900,000 shares) for the
period, after giving effect to the estimated number of shares that would be
required to be sold at the initial public offering price, after deducting the
underwriting discount, to fund the distribution to the current stockholders of
all previously taxed, but undistributed, S corporation earnings, estimated at
$8,239,815 (or 886,002 shares) had the termination occurred on March 31, 1998.
The Company does not have any common stock equivalents.

5. BORROWING ARRANGEMENTS:
 
     Effective June 1, 1998, the Company renewed its revolving credit agreement
with a bank (the Credit Agreement). Under the Credit Agreement, the Company may
borrow up to $10,000,000 ($8,000,000 as of December 31, 1997) with borrowings
limited to the sum of 80% of eligible accounts receivable plus 35% of eligible
inventories, as defined. Borrowings under the Credit Agreement were $1,055,103
and $3,935,417 as of March 31, 1998 and December 31, 1997, respectively, with
interest at the bank's reference rate. Borrowings under the Credit Agreement
were $2,796,528 with interest at the bank's reference rate plus 0.50% as of
December 31, 1996. The bank's reference rate was 8.25%, 8.5% and 8.5% as of
December 31, 1996 and 1997 and March 31, 1998, respectively.
 
     The line of credit is collateralized by substantially all assets of the
Company. The agreement includes various covenants, including requirements to
maintain certain levels of net income and tangible net worth and limitations on
the payment of dividends and property and equipment acquisitions.
 
     Included in cash on the balance sheet is $114,000, $260,000 and $119,231 as
of December 31, 1996 and 1997 and March 31, 1998, respectively, which was held
in a restricted collateral cash account. These amounts were applied to reduce
bank borrowings in the month following the period end.
 
6. DEFERRED COMPENSATION AGREEMENT:
 
     The Company has a deferred compensation agreement with a retired officer
who is also a stockholder. The Company is obligated to pay the retired officer
(or a designated beneficiary) $7,000 per month for 60 months beginning January
1996. The Company's obligation under the agreement is not funded. The present
value of the Company's liability related to the deferred compensation agreement
was $275,997, $216,939 and $195,909 as of December 31, 1996 and 1997 and March
31, 1998, respectively, with interest computed at 10%.
 
     Interest expense related to the agreement was $27,794, $24,942, $8,964 and
$6,970 for the years ended December 31, 1996 and 1997 and for the three months
ended March 31, 1997 and 1998, respectively (none in 1995). The Company recorded
$54,675 of compensation expense related to the agreement in the year ended
December 31, 1995.
 
7. LEASE COMMITMENTS AND CONTINGENCIES:
 
     The Company leases an office and warehouse facility under terms of an
operating lease with a partnership in which a stockholder of the Company is a
general partner. During 1997, the office and warehouse facility were sold to a
limited liability partnership in which all stockholders of the Company are
limited partners. In connection with the purchase of the property, the limited
liability partnership executed promissory notes in favor of a bank and a
stockholder of the Company. The Company has guaranteed payments due under these
notes. As of March 31, 1998, the balances of the notes payable to the bank and
the stockholder were $955,556 and $1,370,903, respectively. The lease expires in
December 1999. The Company also leases office space from nonaffiliated entities
under operating lease agreements that expire at various dates through 2000. In
addition to minimum rents, the leases require the Company to pay certain
operating costs of the lessor.

the 401(k) portion of the plan. The Company is required to match 50% of an
employee's contribution up to the first 6% of an employee's eligible

9. COMMON STOCK BUY-SELL AGREEMENT:
 
     The Company and its stockholders entered into a Stock Purchase Agreement
(the Agreement) effective April 1, 1992 that restricts the right of stockholders
to dispose of or encumber any shares of the Company's common stock and dictates
terms for transfer of the shares. Upon the death, disability or termination of
employment, each stockholder is required to put his shares to the Company, and
the Company is obligated to purchase all shares owned by that stockholder at a
price determined pursuant to terms of the Agreement. In connection therewith,
the value of the common stock subject to put options has been accreted to the
value determined according to terms of the Agreement. Effective November 1,
1996, the Agreement was amended to allow a retired stockholder to retain his
shares until either he or his legal representative require the Company to
purchase his shares, or until his death.
 
     In connection with the Offering, and pursuant to accounting rules and
regulations applicable to public companies, the Company has adjusted its
financial statements to reclassify the carrying value of common stock pursuant
to the Agreement out of stockholders' equity. The effect of this restatement was

policies with a combined face value of $1,000,000 insuring the life of the

11. RECAPITALIZATION:
 
     As discussed in Notes 2 and 3, the Company is contemplating an initial
public offering of 2,600,000 shares of its common stock (the Offering). In
connection therewith, on June 1, 1998, the Company's Board of Directors and
stockholders approved an amendment to the Company's Certificate of Incorporation
to be filed prior to the Offering to increase the number of authorized shares of
common stock to 50,000,000 and change the par value of the common stock to
$0.001. Pursuant to the Company's amended Certificate of Incorporation, all such
authorized shares are deemed to be common stock until otherwise designated by
the Board of Directors. Also, on June 1, 1998, the Company's Board of Directors
and stockholders authorized a 690-for-1 stock split of its common stock to be
effected prior to the Offering. The stock split has been retroactively reflected
in the accompanying financial statements.
 
     In connection with the Offering, the Company has reserved an aggregate of
950,000 shares of common stock for issuance pursuant to the Company's Incentive
Compensation Plan. The terms of the plan allow for a variety of awards including
stock options, stock appreciation rights, restricted stock, performance shares,
performance units, cash-based awards, phantom shares and other share-based
awards as determined by the Company's Compensation Committee (the Committee).
Also, in connection with the Offering, the Company has reserved 250,000 shares
of common stock for issuance pursuant to the Company's Employee Stock Purchase
Plan. Under terms of the Employee Stock Purchase Plan, eligible employees will
be granted an option to purchase a designated number of shares of common stock
at a purchase price as determined by the Committee, but at no less than 85% of
the lower of the market price on the first or last day of the purchase period.

12. BUSINESS ACQUISITION:
 
     In June 1998, the Company entered into a nonbinding letter of intent to
acquire Direct Connect Systems, Inc. ("DCSI"), a Marietta, Georgia-based firm
engaged in the analysis, custom design, integration and support of high-end Open
Systems data storage solutions principally for end-users located in the
Southeastern portion of the United States. In addition to its Marietta
headquarters, DCSI has field sales offices in Herndon, Virginia, Charlotte,

conditions, including the Company's due diligence investigation of DCSI's
business and financial affairs as well as execution of a definitive agreement.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Company's Amended and Restated Articles of Incorporation limit the
liability of directors to the maximum extent permitted by the Minnesota Business
Corporation Act. Specifically, directors will not be personally liable for
monetary damages for breach of their fiduciary duties as directors, except for
liability due to (i) any breach of the duty of loyalty to the Company or its
stockholders, (ii) acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) dividends or other
distributions of corporate assets that are in contravention of certain statutory
or contractual restrictions; (iv) violations of certain Minnesota securities
laws, or (v) any transaction from which the director derives an improper
personal benefit. Liability under the federal securities laws is not limited by
the Amended and Restated Articles of Incorporation.
 
     The Minnesota Business Corporation Act requires that the Company indemnify
any director or officer made or threatened to be made a party to a legal
proceeding, by reason of the former or present official capacity of the person,
against judgments, penalties, fines, settlements and reasonable expenses
incurred in connection with the proceeding if certain statutory standards are
met. A "proceeding" means a threatened, pending or completed civil, criminal,
administrative, arbitration or investigative proceeding, including a derivative
action in the name of the Company. Reference is made to the detailed terms of
the Minnesota indemnification statute (Minn. Stat. Section 302A.521) for a
complete statement of such indemnification rights. The Company's Amended and
Restated Articles of Incorporation also require the Company to provide
indemnification of these persons to the fullest extent of the Minnesota
indemnification statute.
 
     The Company has entered into an indemnification agreement with each of its
directors and executive officers to provide him or her with specific contractual
assurances that the indemnification protection provided by the Minnesota
Business Corporation Act and the Company's Amended and Restated Articles of
Incorporation will be available to such director or officer and to provide for
the indemnification of and the advancing of expenses to such director or officer
to the fullest extent permitted by law. The Company also presently maintains
insurance to protect itself and its directors and officers against certain
liabilities, costs, and expenses arising out of claims or suits against such
directors and officers resulting from their service in such capacity.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
     Contemporaneously with the closing of this offering, the Company will grant
the four non-employee directors and 68 employees of the Company options to
purchase an aggregate of 214,750 shares of the Company's Common Stock, which
options are exercisable at the initial public offering price shown on the cover
page of the Prospectus. The Company believes that the grant of these options are
exempt from registration under the Securities Act because no sale of securities
occurred.

ITEM 17. UNDERTAKINGS.
 
     The undersigned 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 by the Registrant for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officers or controlling persons of the
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 hereunder, the Registrant will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of competent jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

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

                      REPORT OF INDEPENDENT ACCOUNTANTS ON
                          FINANCIAL STATEMENT SCHEDULE
 
     In connection with our audits of the financial statements of Datalink
Corporation as of December 31, 1996 and 1997, and for each of the three years in
the period ended December 31, 1997, which financial statements are included in
the Prospectus, we have audited the financial statement schedule listed in Item
16(b) herein.
 
     In our opinion, this financial statement schedule, when considered in
relation to the basic financial statements taken as a whole, presents fairly, in
all material aspects, the information required to be included therein.

         The Company and the Selling Stockholder confirm as follows their

         1.       Agreement to Sell and Purchase.

         (a) On the basis of the representations, warranties and agreements of
the Company and the Selling Stockholder herein contained and subject to all the
terms and conditions of this Agreement, (i) the Company agrees to issue and sell
the Company Firm Shares to the several Underwriters and (ii) each of the
Underwriters, severally and not jointly, agrees to purchase from the Company the
respective number of Firm Shares set forth opposite that Underwriter's name in
Schedule I hereto, at the purchase price of $____ for each Firm Share.

         (b) Subject to all the terms and conditions of this Agreement, the
Company and the Selling Stockholder grant the Option to the several Underwriters
to purchase, severally and not jointly, up to the maximum number of Option
Shares set forth in Schedule II hereto at the same price per share as the
Underwriters shall pay for the Firm Shares. The Option may be exercised only to
cover over-allotments in the sale of the Firm Shares by the Underwriters and may
be exercised in whole or in part at any time (but not more than once) on or
before the 30th day after the date of this Agreement upon written or telegraphic
notice (the "Option Shares Notice") by the Representatives to the Company and
the Selling Stockholder no later than 12:00 noon, New York City time, at least
two and no more than five business days before the date specified for closing in
the Option Shares Notice (the "Option Closing Date"), setting forth the
aggregate number of Option Shares to be purchased and the time and date for such
purchase. On the Option Closing Date, the Company will issue and sell and the
Selling Stockholder will sell to the Underwriters the number of Option Shares
set forth in the Option Shares Notice (all Option Shares will be purchased from
the Selling Stockholder before any Option Shares are purchased from the
Company), and each Underwriter will purchase such percentage of the Option
Shares as is equal to the percentage of Firm Shares that such Underwriter is
purchasing, as adjusted by the Representatives in such manner as they deem
advisable to avoid fractional shares.

         2. Delivery and Payment. Delivery of the Firm Shares shall be made to
the Representatives for the accounts of the Underwriters against payment of the
purchase price by certified or official bank checks or by wire transfers payable
in same-day funds to the order of the Company for the Company Firm Shares to be
sold by it at the office of Needham & Company, Inc., 445 Park Avenue, New York,
New York 10022, at 10:00 a.m., New York City time, on the third (or, if the
purchase price set forth in Section 1(b) hereof is determined after 4:30 p.m.,
Washington D.C. time, the fourth) business day following the commencement of the
offering contemplated by this Agreement, or at such time on such other date, not
later than seven business days after the date of this Agreement, as may be
agreed upon by the Company and the Representatives (such date is hereinafter
referred to as the "Closing Date").

         To the extent the Option is exercised, delivery of the Option Shares
against payment by the Underwriters (in the manner specified above for the
Company and, in the case of Options Shares, if any, to be sold by the Selling
Stockholder, the Selling Stockholder) will take place at the offices specified
above for the Closing Date at the time and date (which may be the Closing Date)
specified in the Option Shares Notice. Payment for the Selling Stockholder
Option Shares, if any, to be sold by the Selling Stockholder shall be made
pursuant to the terms of the Selling Stockholder's Letter of Transmittal and
Custody Agreement between the Selling Stockholder and Messerli and Kramer P.A.
as custodian.

                                       2

         Certificates evidencing the Shares shall be in definitive form and
shall be registered in such names and in such denominations as the
Representatives shall request at least two business days prior to the Closing
Date or the Option Closing Date, as the case may be, by written notice to the
Company. For the purpose of expediting the checking and packaging of
certificates for the Shares, the Company agrees to make such certificates
available for inspection at least 24 hours prior to the Closing Date or the
Option Closing Date, as the case may be.

         The cost of original issue tax stamps, if any, in connection with the
issuance and delivery of the Firm Shares and Option Shares by the Company to the
respective Underwriters shall be borne by the Company. The Company will pay and
save each Underwriter and any subsequent holder of the Shares harmless from any
and all liabilities with respect to or resulting from any failure or delay in
paying Federal and state stamp and other transfer taxes, if any, which may be
payable or determined to be payable in connection with the original issuance or
sale to such Underwriter of the Shares.

         3. Representations and Warranties of the Company. The Company
represents, warrants and covenants to each Underwriter that:

         (a) A registration statement (Registration No. 333-___) on Form S-1
relating to the Shares, including a preliminary prospectus and such amendments
to such registration statement as may have been required to the date of this
Agreement, has been prepared by the Company under the provisions of the
Securities Act of 1933, as amended (the "Act"), and the rules and regulations
(collectively referred to as the "Rules and Regulations") of the Securities and
Exchange Commission (the "Commission") thereunder, and has been filed with the
Commission. The term "preliminary prospectus" as used herein means a preliminary
prospectus as contemplated by Rule 430 or Rule 430A of the Rules and Regulations
included at any time as part of the registration statement. Copies of such
registration statement and amendments and of each related preliminary prospectus
have been delivered to the Representatives. If such registration statement has
not become effective, a further amendment to such registration statement,
including a form of final prospectus, necessary to permit such registration
statement to become effective will be filed promptly by the Company with the
Commission. If such registration statement has become effective, a final
prospectus containing information permitted to be omitted at the time of
effectiveness by Rule 430A of the Rules and Regulations will be filed promptly
by the Company with the Commission in accordance with Rule 424(b) of the Rules
and Regulations. The term "Registration Statement" means the registration
statement as amended at the time it becomes or became effective (the "Effective
Date"), including financial statements and all exhibits and any information
deemed to be included by Rule 430A and includes any registration statement
relating to the offering contemplated by this Agreement and filed pursuant to
Rule 462(b) of the Rules and Regulations. The term "Prospectus" means the
prospectus as first filed with the Commission pursuant to Rule 424(b) of the
Rules and Regulations or, if no such filing is required, the form of final
prospectus included in the Registration Statement at the Effective Date. Any
reference herein to the terms "amend," "amendment" or "supplement" with respect
to the Registration Statement, any preliminary prospectus or the Prospectus
shall be deemed to refer to and include the filing of any document under the
Securities Exchange Act of 1934, as amended (the "Exchange Act") after the
Effective Date, the date of any preliminary prospectus or the date of the
Prospectus, as the case may be, and deemed to be incorporated therein by
reference.

<PAGE>   4

         (b) No order preventing or suspending the use of any preliminary
prospectus has been issued by the Commission. On the Effective Date, the date
the Prospectus is first filed with the Commission pursuant to Rule 424(b) (if
required), at all times subsequent to and including the Closing Date and, if
later, the Option Closing Date and when any post-effective amendment to the
Registration Statement becomes effective or any amendment or supplement to the
Prospectus is filed with the Commission, the Registration Statement and the
Prospectus (as amended or as supplemented if the Company shall have filed with
the Commission any amendment or supplement thereto), including the financial
statements included in the Prospectus, did and will comply with all applicable
provisions of the Act and the Rules and Regulations and will contain all
statements required to be stated therein in accordance with the Act and the
Rules and Regulations. On the Effective Date and when any post-effective
amendment to the Registration Statement becomes effective, no part of the
Registration Statement, the Prospectus or any such amendment or supplement did
or will contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary in order to make the
statements therein not misleading. At the Effective Date, the date the
Prospectus or any amendment or supplement to the Prospectus is filed with the
Commission and at the Closing Date and, if later, the Option Closing Date, the
Prospectus did not and will not contain any untrue statement of a material fact
or omit to state a material fact necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading. The
foregoing representations and warranties in this Section 3(b) do not apply to
any statements or omissions made in reliance on and in conformity with
information relating to any Underwriter furnished in writing to the Company by
the Representatives specifically for inclusion in the Registration Statement or
Prospectus or any amendment or supplement thereto.

         (c) The Company does not own, and at the Closing Date and, if later,
the Option Closing Date, will not own, directly or indirectly, any shares of

association or other entity. The Company is, and at the Closing Date and, if
later, the Option Closing Date, will be, a corporation duly organized, validly
existing and in good standing under the laws of its jurisdiction of
incorporation. The Company has, and at the Closing Date and, if later, the

Closing Date, will be, duly licensed or qualified to do business and in good
standing as a foreign corporation in all jurisdictions in which the nature of
the activities conducted by it or the character of the assets owned or leased by
it makes such license or qualification necessary, except to the extent that the
failure to be so qualified or be in good standing would not materially and
adversely affect the Company or its business, properties, business prospects,
condition (financial or other) or results of operations. The Company is not, and
at the Closing Date and, if later, the Option Closing Date, will not be, engaged
in any discussions or a party to any agreement or understanding, written or
oral, regarding the acquisition of an interest in any corporation, firm,
partnership, joint venture, association or other entity where such discussions,
agreements or understandings would require amendment to the Registration
Statement pursuant to applicable securities laws other than as described in the
Prospectus. Complete and correct copies of the articles of incorporation and of
the by-laws of the Company and all amendments thereto have



                                       4

         (d) All of the outstanding shares of capital stock of the Company
(including the Selling Stockholder Option Shares to be sold by the Selling
Stockholder under this Agreement) have been duly authorized, validly issued and
are fully paid and nonassessable and were issued in compliance with all

Closing Date, will not have outstanding, any options to purchase, or any rights
or warrants to subscribe for, or any securities or obligations convertible into,
or any contracts or commitments to issue or sell, any shares of capital stock,
or any such warrants, convertible securities or obligations. No further approval
or authority of stockholders or the Board of Directors of the Company will be
required for the transfer and sale of the Company Firm Shares and the Option
Shares as contemplated herein.

         (e) The financial statements and schedules included in the Registration
Statement or the Prospectus present fairly the financial condition of the
Company as of the respective dates thereof and the results of operations and

properties, business prospects, condition (financial or otherwise) or results of

it is a party or by which its property is bound or affected, which default might

business prospects, condition (financial or other) or results of operations of
the Company. To the best knowledge of the Company, no other party under any

dissolution or other event.

Company and the Selling Stockholder respectively covenants and agrees with the
several Underwriters as follows:

         (a) The Company will not, either prior to the Effective Date or
thereafter during such period as the Prospectus is required by law to be
delivered in connection with sales of the Shares by an Underwriter or dealer,
file any amendment or supplement to the Registration Statement or the
Prospectus, unless a copy thereof shall first have been submitted to the
Representatives within a reasonable period of time prior to the filing thereof
and the Representatives shall not have objected thereto in good faith.

         (b) The Company will use its best efforts to cause the Registration
Statement to become effective, and will notify the Representatives promptly, and
will confirm such advice in writing, (i) when the Registration Statement has
become effective and when any post-effective amendment thereto becomes
effective, (ii) of any request by the Commission for amendments or supplements
to the Registration Statement or the Prospectus or for additional information,
(iii) of the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or the initiation of any proceedings
for that purpose or the threat thereof, (iv) of the happening of any event
during the period mentioned in the second sentence of Section 5(e) that in the
judgment of the Company makes any statement made in the Registration Statement
or the Prospectus untrue or that requires the making of any changes in the
Registration Statement or the Prospectus in order to make the statements
therein, in the light of the circumstances in which they are made, not
misleading and (v) of receipt by the Company or any representative or attorney
of the Company of any other communication from the Commission relating to the
Company, the Registration Statement, any preliminary prospectus or the
Prospectus. If at any time the Commission shall issue

                                       13
<PAGE>   14

any order suspending the effectiveness of the Registration Statement, the
Company will make every reasonable effort to obtain the withdrawal of such order
at the earliest possible moment. If the Company has omitted any information from
the Registration Statement pursuant to Rule 430A of the Rules and Regulations,
the Company will comply with the provisions of and make all requisite filings
with the Commission pursuant to said Rule 430A and notify the Representatives
promptly of all such filings.

         (d) The Company will comply with all the provisions of any undertakings
contained in the Registration Statement.

         (e) On the Effective Date, and thereafter from time to time, the
Company will deliver to each of the Underwriters, without charge, as many copies
of any preliminary prospectus and the Prospectus or any amendment or supplement
thereto as the Representatives may reasonably request. The Company consents to
the use of the Prospectus or any amendment or supplement thereto by the several
Underwriters and by all dealers to whom the Shares may be sold, both in
connection with the offering or sale of the Shares and for any period of time
thereafter during which the Prospectus is required by law to be delivered in
connection therewith. During the period in which a prospectus is required by law
to be delivered by an Underwriter or dealer, the Company will comply with all
requirements imposed upon it by the Act and the Rules and Regulations, as from
time to time in force, so far as necessary to permit the continuance of sales of
or dealings in the Shares as contemplated by the provisions hereof or the
Prospectus. If during such period of time any event shall occur which in the
judgment of the Company or counsel to the Underwriters should be set forth in
the Prospectus in order to make any statement therein, in the light of the
circumstances under which it was made, not misleading, or if it is necessary to
supplement or amend the Prospectus to comply with law, the Company will
forthwith prepare and duly file with the Commission an appropriate supplement or
amendment thereto, and will deliver to each of the Underwriters, without charge,
such number of copies of such supplement or amendment to the Prospectus as the
Representatives may reasonably request. The Company will not file any document
under the Exchange Act or the Exchange Act Rules and Regulations before the
termination of the offering of the Shares by the Underwriters, if such document
would be deemed to be incorporated by reference into the Prospectus, that is not
approved by the Representatives after reasonable notice thereof. In case any
Underwriter is required to deliver a prospectus in connection with sales of any
Shares at any time nine months or more after the effective date of the
Registration Statement, upon the request of the Representatives but at the
expense of such Underwriter, the Company will prepare and deliver to such
Underwriter as many copies as the Representatives may request of an amended or
supplemented Prospectus complying with Section 10(a)(3) of the Act.

action which would subject it to general service of process in any jurisdiction
where it is not now so subject.

Representatives and each other Underwriter who may so request a copy of each
annual or other report it shall be required to file with the National

to the requirements of the NASD or with the Commission pursuant to the Act or
the Exchange Act.

securities as soon as may be practicable but in no event later than the last day

Effective Date, and satisfying the provisions of Section 11(a) of the Act
(including Rule 158 of the Rules and Regulations).

themselves, all costs and expenses incident to the performance of the

designated pursuant to Section 5(f), including the fees, disbursements and other
charges of counsel to the Underwriters in connection therewith, and the

memoranda, (viii) fees, disbursements and other charges of counsel to the
Company (but not those of counsel for the Underwriters, except as otherwise

for the Shares. In addition, the Company will pay all travel and lodging
expenses incurred by management of the Company in connection with any
informational "road show" meetings held in connection with the offering and will

meetings. The Company shall not, however, be required to pay for any of the
Underwriters' expenses (other than those related to qualification of the Shares
under state securities or Blue Sky laws and those incident to securing any
required review by the NASD of the terms of the sale of the shares) except that,
if this Agreement shall not be consummated because the conditions in Section 6
hereof are not satisfied, or because this Agreement is terminated by the
Representatives pursuant to Section 9 hereof, or by reason of any failure,
refusal or inability on the part of the Company to perform any undertaking or
satisfy any condition of this Agreement or to comply with any of the terms
hereof on its part to be performed, unless such failure to satisfy said
condition or to comply with said terms shall be due to the default or omission
of any Underwriter, then the Company shall promptly upon request by the
Representatives reimburse the several Underwriters for all out-of-pocket
accountable expenses, including fees and disbursements of counsel, incurred in
connection with investigating, marketing and proposing to market the Shares or
in contemplation of performing their obligations hereunder; but the Company
shall not in any event be liable to any of the several Underwriters for damages
on account of loss of anticipated profits from the sale by them of the Shares.

expenses incident to the performance of his obligations under this Agreement
that are not otherwise specifically provided for herein, including but not
limited to any fees and expenses of counsel for such Selling Stockholder, any
fees and expenses of the Attorneys-in-Fact and the Custodian, and all expenses
and taxes incident to the sale and delivery of the Shares to be sold by such
Selling Stockholder to the Underwriters hereunder.

         (k) The Company will not at any time, directly or indirectly, take any
action designed or which might reasonably be expected to cause or result in, or
which will constitute, stabilization of the price of the shares of Common Stock
to facilitate the sale or resale of any of the Shares.

         (l) The Company will apply the net proceeds from the offering and sale

         or the character of the assets owned or leased by it makes such license
         or qualification necessary and where the failure to be licensed or

         financial condition of the Company.

                  (ii) All of the outstanding shares of capital stock of the

         to any of the Shares or the issue and sale thereof.

                  (iv) To such counsel's knowledge, the Company does not own or
         control, directly or indirectly, any shares of stock or any other
         equity or long-term debt securities of any corporation or have any
         equity interest in any corporation, firm, partnership, joint venture,
         association or other entity.

                  (v) The number of shares of authorized and outstanding
         capital stock of the Company is as set forth in the Registration
         Statement and the Prospectus in the column entitled "Actual" under the
         caption "Capitalization" (except for subsequent issuances, if any,
         pursuant to this Agreement or pursuant to reservations, agreements,
         employee benefit plans or the exercise of convertible securities,
         options or warrants referred to in the Prospectus). To such counsel's
         knowledge, except as disclosed in or specifically contemplated by the 
         Prospectus, there are no outstanding options, warrants of other rights
         calling for the issuance of, and no commitments, plans or arrangements
         to issue, any shares of capital stock of the Company or any security
         convertible into or exchangeable or exercisable for capital stock of
         the Company. The description of the capital stock of the Company in
         the Registration Statement and the Prospectus conforms in all material
         respects to the terms thereof.


                  (vi) To such counsel's knowledge, there are no legal or
         governmental proceedings pending or threatened to which the Company is
         a party or to which any of its properties is subject that are required
         to be described in the Registration Statement or the Prospectus but are
         not so described.

                  (vii) No consent, approval, authorization or order of, or any
         filing or declaration with, any court or governmental agency or body is
         required for the consummation by the Company of the transactions on its
         part contemplated under this Agreement, except such as have been
         obtained or made under the Act or the Rules and Regulations and such as
         may be

                                       19
<PAGE>   20

         required under state securities or Blue Sky laws or the by-laws and
         rules of the NASD in connection with the purchase and distribution by
         the Underwriters of the Shares.

                  (viii) The Company has full corporate power and authority to
         enter into this Agreement. This Agreement has been duly authorized,
         executed and delivered by the Company.

                  (ix) The execution and delivery of this Agreement, the
         compliance by the Company with all of the terms hereof and the
         consummation of the transactions contemplated hereby does not
         contravene any provision of applicable law or the Articles of
         Incorporation or By-Laws of the Company, and to the best of such
         counsel's knowledge will not result in the creation or imposition of
         any lien, charge or encumbrance upon any of the assets of the Company
         pursuant to the terms and provisions of, result in a breach or
         violation of any of the terms or provisions of, or constitute a default
         under, or give any party a right to terminate any of its obligations
         under, or result in the acceleration of any obligation under, any
         indenture, mortgage, deed of trust, voting trust agreement, loan
         agreement, bond, debenture, note agreement or other evidence of
         indebtedness, lease, contract or other agreement or instrument known to
         such counsel to which the Company is a party or by which the Company or
         any of its properties is bound or affected, or violate or conflict with
         (i) any judgment, ruling, decree or order known to such counsel or (ii)
         any statute, rule or regulation of any court or other governmental
         agency or body, applicable to the business or properties of the Company
         except for such liens, charges, encumbrances, breaches, violations or
         terminations as would not reasonably be expected to have a material and
         adverse effect on business, properties or results of operations of the
         Company.

                  (x) To such counsel's knowledge, there is no document or
         contract of a character required to be described in the Registration
         Statement or the Prospectus or to be filed as an exhibit to the
         Registration Statement which is not described or filed or incorporated
         by reference as required, and each description of such contracts and
         documents that is contained in the Registration Statement and
         Prospectus fairly presents in all material respects the information
         required under the Act and the Rules and Regulations.

                  (xi) The statements under the captions "Risk Factors -- Shares
         Eligible for Future Sale," "Risk Factors -- Undesignated Shares,
         Certain Anti-Takeover Provisions, "Management -- Stock Incentive
         Plans," "Management -- Indemnification Agreements," "Certain
         Transactions," "Description of Capital Stock," and "Shares Eligible for
         Future Sale" in the Prospectus, insofar as the statements constitute a
         summary of documents referred to therein or matters of law, are
         accurate summaries and fairly and correctly present, in all material
         respects, the information called for with respect to such documents and
         matters (provided, however, that such counsel may rely on
         representations of the Company with respect to the factual matters
         contained in such statements, and provided further that such counsel
         shall state that nothing has come to the attention of such counsel
         which leads them to believe that such representations are not true and
         correct in all material respects).

                                       20
<PAGE>   21

                  (xii) The Company is not an "investment company" or an
         "affiliated person" of, or "promoter" or "principal underwriter" for,
         and immediately upon completion of the sale of Shares contemplated
         hereby will not be, an "investment company," as such terms are defined
         in the Investment Company Act of 1940, as amended.

                  (xiii) The Selling Stockholder Shares are duly listed on the
         NNM and the Company Shares have been duly authorized for listing on the
         NNM, subject to notice of issuance.

                  (xiv) To such counsel's knowledge, no holder of securities of
         the Company has rights, which have not been waived, to require the
         Company to register with the Commission shares of Common Stock or other
         securities, as part of the offering contemplated hereby.

                  (xv) The Registration Statement has become effective under the
         Act, and to the best of such counsel's knowledge, no stop order
         suspending the effectiveness of the Registration Statement has been
         issued and no proceeding for that purpose has been instituted or is
         pending, threatened or contemplated.

                  (xvi) The Registration Statement and the Prospectus comply as
         to form in all material respects with the requirement of the Act and
         the Rules and Regulations (other than the financial statements,
         schedules and other financial and statistical data contained in the
         Registration Statement or the Prospectus, as to which such counsel need
         express no opinion).

                  (xvii) Such counsel has participated in the preparation of the
         Registration Statement and Prospectus and has no reason to believe
         that, as of the Effective Date the Registration Statement, or any
         amendment or supplement thereto, (other than the financial statements,
         schedules and other financial and statistical data contained therein,
         as to which such counsel need express no opinion) contained any untrue
         statement of a material fact or omitted to state a material fact
         required to be stated therein or necessary to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading or that the Prospectus, or any amendment or supplement
         thereto, as of its date and the Closing Date and, if later, the Option
         Closing Date, contained or contains any untrue statement of a material
         fact or omitted or omits to state a material fact necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading (other than the financial statements,
         schedules and other financial and statistical data contained therein,
         as to which such counsel need express no opinion). Such counsel may
         express the statements set forth in this clause (xvii) in a letter
         separate from its opinion.

                  (xviii) The documents incorporated by reference in the
         Prospectus or any further amendment or supplement thereto made by the
         Company prior to the Closing Date or the Option Closing Date, as the
         case may be, (other than the financial statements, schedules and other
         financial and statistical data contained therein, as to which such
         counsel need express no opinion), when they became effective or were
         filed with the Commission, as the case

                                       21
<PAGE>   22

         may be, complied as to form in all material respects with the
         requirements of the Exchange Act and the Exchange Act Rules and
         Regulations.

                  (xix) This Agreement and the Stockholder's Agreement have each
         been duly executed and delivered by or on behalf of the Selling
         Stockholder; the Stockholder's Agreement constitutes a valid and
         binding agreement of such Selling Stockholder in accordance with its
         terms, except as enforceability may be limited by the application of
         bankruptcy, insolvency or other laws affecting creditors' rights
         generally or by general principles of equity; the Attorneys-in-Fact and
         the Custodian have been duly authorized by such Selling Stockholder to
         deliver the Shares on behalf of such Selling Stockholder in accordance
         with the terms of this Agreement; and the sale of the Shares to be sold
         by such Selling Stockholder hereunder, the performance by such Selling
         Stockholder of this Agreement and the Stockholder's Agreement and the
         consummation of the transactions contemplated hereby and thereby will
         not result in a breach or violation of any of the terms or provisions
         of, or constitute a default under, or give any party a right to
         terminate any of its obligations under, or result in the acceleration
         of any obligation under any indenture, mortgage, deed of trust, voting
         trust agreement, loan agreement, bond, debenture, note agreement or
         other evidence of indebtedness, lease, contract or other agreement or
         instrument to which such Selling Stockholder is a party or by which
         such Selling Stockholder or any of its properties is bound or affected
         known to counsel, or violate or conflict with any judgment, ruling,
         decree, order, statute, rule or regulation of any court or other
         governmental agency or body applicable to such Selling Stockholder
         known to such counsel.

                  (xx) No consent, approval, authorization or order of, or any
         filing or declaration with, any court or governmental agency or body is
         required for the consummation by the Selling Stockholder of the
         transactions on his part contemplated by this Agreement, except such as
         have been obtained or made under the Act or the Rules and Regulations
         and such as may be required under state securities or Blue Sky laws or
         the by-laws and rules of the NASD in connection with the purchase and
         distribution by the Underwriters of the Shares.

                  (xxi) The Selling Stockholder has full legal right, power and
         authority to enter into this Agreement and the Stockholder's Agreement
         and to sell, assign, transfer and deliver the Shares to be sold by such
         Selling Stockholder hereunder and, upon payment for such Shares and
         assuming that the Underwriters are purchasing such Shares in good faith
         and without notice of any other adverse claim within the meaning of the
         Uniform Commercial Code, the Underwriters will have acquired all rights
         of such Selling Stockholder in such Shares free of any adverse claim,
         any lien in favor of the Company and any restrictions on transfer
         imposed by the Company.

                  (xxii) To the knowledge of such counsel, the Company holds and
         is operating in compliance with all licenses, approvals, certificates
         and permits from governmental and regulatory authorities, foreign and
         domestic, which are necessary to the conduct of its business as
         currently being conducted and as described in the Prospectus. To the
         knowledge of such counsel, the Company has not received notice of or
         has knowledge of any basis for any proceeding or action relating
         specifically to the Company for the

                                       22
<PAGE>   23

         revocation or suspension of any such consent, authorization, approval,
         order, license, certificate, permit or any other action or proposed
         action by any regulatory authority having jurisdiction over the Company
         that would have a material adverse effect on the Company.

                  (xxiii) To the knowledge of such counsel, the Company owns or
         licenses all patents, patent applications, trademarks, service marks,
         tradenames, trademark registrations, service mark registrations,
         copyrights, licenses, inventions, trade secrets and other similar
         rights necessary for the conduct of its business as currently being
         conducted and as described in the Prospectus. To the knowledge of such
         counsel, no aspect of the business of the Company involves or gives
         rise to any infringement of or license or similar fees for any patents,
         patent applications, trademarks, service marks, tradenames, trademark
         registrations, service mark registrations, copyrights, licenses,
         inventions, trade secrets or other similar rights of others, and the
         Company has not received any notice or claim of conflict with the
         asserted rights of others with respect to any of the foregoing.

         In rendering the opinions in subparagraphs (xix) - (xxi), such counsel
may rely upon opinions of other counsel retained by the Selling Stockholder
reasonably acceptable to the Representatives and as to matters of fact on
certificates of the Selling Stockholder, officers of the Company and
governmental officials and the representations and warranties of the Company and
the Selling Stockholder contained in this Agreement and the Stockholder's
Agreement, provided that the opinion of counsel to the Company and Selling
Stockholder shall state that they are doing so, that they have no reason to
believe that they and the Underwriters are not entitled to rely on such opinions
or certificates and that copies of such opinions or certificates are attached to
the opinion.

         In rendering such opinion, such counsel may rely upon as to matters of
local law on opinions of counsel satisfactory in form and substance to the
Representatives and counsel for the Underwriters, provided that the opinion of
counsel to the Company and the Selling Stockholder shall state that they are
doing so, that they have no reason to believe that they and the Underwriters are
not entitled to rely on such opinions and that copies of such opinions are
attached to the opinion.

         (g) The representatives shall have received an opinion, dated the
Closing Date and the Option Closing Date, from Kaplan, Strangis and Kaplan,
P.A., counsel to the Underwriters, with respect to the Registration Statement,
the Prospectus and this Agreement, which opinion shall be satisfactory in all
respects to the Representatives.

         (h) Concurrently with the execution and delivery of this Agreement, the
Accountants shall have furnished to the Representatives a letter, dated the date
of its delivery, addressed to the Representatives and in form and substance
satisfactory to the Representatives, confirming that they are independent
accountants with respect to the Company as required by the Act and the Rules and
Regulations and with respect to certain financial and statistical information
contained in the Registration Statement. At the Closing Date and, as to the
Option Shares, the Option Closing Date, the Accountants shall have furnished to
the Representatives a letter, dated the date of its delivery, which shall
confirm, on the basis of a review in accordance with the procedures set forth in
the letter from the Accountants, that nothing has come to their attention during
the period from the date

                                       23
<PAGE>   24

of the letter referred to in the prior sentence to a date (specified in the
letter) not more than five days prior to the Closing Date and the Option Closing
Date, as the case may be, which would require any change in their letter dated
the date hereof if it were required to be dated and delivered at the Closing
Date and the Option Closing Date.

         (i) Concurrently with the execution and delivery of this Agreement and
at the Closing Date and, as to the Option Shares, the Option Closing Date, there
shall be furnished to the Representatives a certificate, dated the date of its
delivery, signed by each of the Chief Executive Officer and the Chief Financial
Officer of the Company, in form and substance satisfactory to the
Representatives, to the effect that:

                  (i) Each signer of such certificate has carefully examined the
         Registration Statement and the Prospectus and (A) as of the date of
         such certificate, such documents are true and correct in all material
         respects and do not omit to state a material fact required to be stated
         therein or necessary in order to make the statements therein, in light
         of the circumstances under which they were made, not untrue or
         misleading, (B) in the case of the certificate delivered at the Closing
         Date and the Option Closing Date, since the Effective Date no event has
         occurred as a result of which it is necessary to amend or supplement
         the Prospectus in order to make the statements therein, in light of the
         circumstances under which they were made, not untrue or misleading, (C)
         subsequent to the respective dates as of which information is given in
         the Registration Statement and the Prospectus, the Company has not
         incurred any material liabilities or obligations, direct or contingent,
         or entered into any material transactions, not in the ordinary course
         of business, or declared or paid any dividends or made any distribution
         of any kind with respect to its capital stock, and except as disclosed
         in the Prospectus, there has not been any change in the capital stock
         (other than a change in the number of outstanding shares of Common
         Stock due to the issuance of shares upon the exercise of outstanding
         options or warrants), or any material change in the short-term or
         long-term debt, or any issuance of options, warrants, convertible
         securities or other rights to purchase the capital stock, of the
         Company, or any material adverse change or any development involving a
         prospective material adverse change (whether or not arising in the
         ordinary course of business), in the general affairs, condition
         (financial or otherwise), business, key personnel, property, prospects,
         net worth or results of operations of the Company, and (D) except as
         stated in the Registration Statement and the Prospectus, there is not
         pending, or, to the knowledge of the Company, threatened or
         contemplated, any action, suit or proceeding to which the Company is a
         party before or by any court or governmental agency, authority or body,
         or any arbitrator, which might result in any material adverse change in
         the condition (financial or otherwise), business, prospects or results
         of operations of the Company.

                  (ii) Each of the representations and warranties of the Company
         contained in this Agreement were, when originally made, and are, at the
         time such certificate is delivered, true and correct.

                  (iii) Each of the covenants required to be performed by the
         Company herein on or prior to the date of such certificate has been
         duly, timely and fully performed and each

<PAGE>   25

         condition herein required to be satisfied or fulfilled on or prior to
         the date of such certificate has been duly, timely and fully satisfied
         or fulfilled.

         (j) Concurrently with the execution and delivery of this Agreement and
at the Closing Date and, as to the Option Shares, the Option Closing Date, there
shall be furnished to the Representatives a certificate, dated the date of its
delivery, signed by the Selling Stockholder (or the Attorneys-in-Fact on his
behalf), in form and substance satisfactory to the Representatives, to the
effect that the representations and warranties of the Selling Stockholder
contained herein are true and correct in all material respects on and as of the
date of such certificate as if made on and as of the date of such certificate,
and each of the covenants and conditions required herein to be performed or
complied with by the Selling Stockholder on or prior to the date of such
certificate has been duly, timely and fully performed or complied with.

         (k) On or prior to the Closing Date, the Representatives shall have
received the executed agreements referred to in Section 5(o).

         (l) The Shares shall be qualified for sale in such jurisdictions as the
Representatives may reasonably request and each such qualification shall be in
effect and not subject to any stop order or other proceeding on the Closing Date
or the Option Closing Date.

         (m) Prior to the Closing Date, the Shares shall have been duly
authorized for listing on the NNM upon official notice of issuance.

         (n) The Company and the Selling Stockholder shall have furnished to the
Representatives such certificates, in addition to those specifically mentioned
herein, as the Representatives may have reasonably requested as to the accuracy
and completeness at the Closing Date and the Option Closing Date of any
statement in the Registration Statement or the Prospectus, as to the accuracy at
the Closing Date and the Option Closing Date of the representations and
warranties of the Company and the Selling Stockholder herein, as to the
performance by the Company and the Selling Stockholder of its and his respective
obligations hereunder, or as to the fulfillment of the conditions concurrent and

         (o) Prior to the Closing Date, the Company shall have furnished the
Representatives with signed copies of the S Corporation Indemnification
Agreements entered into between the Company and each stockholder of the Company
under which the stockholders of the Company indemnify the Company for certain
potential income tax liabilities incurred by the Company as a result of any
failure of the Company to qualify as an S corporation under the Internal Revenue
Code of 1986, as amended (the "Code") for any taxable period ending on or prior
to the Closing Date.

         If any of the conditions hereinabove provided for in this Section 6
shall not have been fulfilled when and as required by this Agreement to be
fulfilled, the obligations of the Underwriters hereunder may be terminated by
the Representatives by notifying the Company of such termination in writing or
by telegram at or prior to the Closing Date or the Option Closing Date, as the
case

                                       25
<PAGE>   26

may be. In such event, the Company and the Underwriters shall not be under any
obligation to each other (except to the extent provided in Sections 5(j) and 7
hereof).

         7.       Indemnification.

(a) The Company and the Selling Stockholder, jointly and severally, will
indemnify and hold harmless each Underwriter, the directors, officers, employees
and agents of each Underwriter and each person, if any, who controls each
Underwriter within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act, from and against any and all losses, claims, liabilities, expenses
and damages (including any and all investigative, legal and other expenses
reasonably incurred in connection with, and any amount paid in settlement of,
any action, suit or proceeding or any claim asserted), to which they, or any of
them, may become subject under the Act, the Exchange Act or other Federal or
state statutory law or regulation, at common law or otherwise, insofar as such
losses, claims, liabilities, expenses or damages arise out of or are based on
(i) any untrue statement or alleged untrue statement of a material fact
contained in any preliminary prospectus, the Registration Statement or the
Prospectus or any amendment or supplement to the Registration Statement or the
Prospectus, or the omission or alleged omission to state in such document a
material fact required to be stated in it or necessary to make the statements in
it not misleading in the light of the circumstances in which they were made,
(ii) any act or failure to act or any alleged act or failure to act by any
Underwriter in connection with, or relating in any manner to, the Common Stock
or the offering contemplated hereby, and which is included as part of or
referred to in any losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arising out of or based upon matters covered by
clause (i) above, and will reimburse each Underwriter and each such controlling
person for any legal or other expenses reasonably incurred by such Underwriter
or such controlling person in connection with investigating or defending any
such action or claim as such expenses are incurred; or arise out of or are based
in whole or in part on any inaccuracy in the representations and warranties of
the Company or the Selling Stockholder contained herein or any failure of the
Company or the Selling Stockholder to perform its or his obligations hereunder
or under law in connection with the transactions contemplated hereby, or (iii)
any failure of the Company's qualification as an S corporation under the Code
for any taxable period ending on or prior to the Closing Date; provided,
however, that (i) the Company and the Selling Stockholder will not be liable to
the extent that such loss, claim, liability, expense or damage arises from the
sale of the Shares in the public offering to any person by an Underwriter and is
based on an untrue statement or omission or alleged untrue statement or omission
made in reliance on and in conformity with information relating to any
Underwriter furnished in writing to the Company by the Representatives, on
behalf of any Underwriter, expressly for inclusion in the Registration
Statement, the preliminary prospectus or the Prospectus; (ii) the Company and
the Selling Stockholder will not be liable to any Underwriter, the directors,
officers, employees or agents of such Underwriter or any person controlling such
Underwriter with respect to any loss, claim, liability, expense, or damage
arising out of or based on any untrue statement or omission or alleged untrue
statement or omission or alleged omission to state a material fact in the
preliminary prospectus which is corrected in the Prospectus if the person
asserting any such loss, claim, liability, charge or damage purchased Shares
from such Underwriter but was not sent or given a copy of the Prospectus at or
prior to the written confirmation of the sale of such Shares to such person; and
(iii) the liability of the Selling Stockholder under this Section 7(a) shall not
exceed the product of the purchase price for each Share set forth in Section
1(a) hereof multiplied by the

                                       26
<PAGE>   27

number of Shares sold by such Selling Stockholder hereunder. This indemnity
agreement will be in addition to any liability that the Company and the Selling
Stockholder might otherwise have.

         (b) Each Underwriter will indemnify and hold harmless the Company, each
director of the Company, each officer of the Company who signs the Registration
Statement, each person, if any, who controls the Company within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act, and the Selling
Stockholder to the same extent as the foregoing indemnity from the Company and
each Selling Stockholder to each Underwriter, as set forth in Section 7(a), but
only insofar as losses, claims, liabilities, expenses or damages arise out of or
are based on any untrue statement or omission or alleged untrue statement or
omission made in reliance on and in conformity with information relating to any
Underwriter furnished in writing to the Company by the Representatives, on
behalf of such Underwriter, expressly for use in the Registration Statement, the
preliminary prospectus or the Prospectus. The Company and the Selling
Stockholder acknowledge that the statements set forth under the heading
"Underwriting" in the preliminary prospectus and the Prospectus constitute the
only information relating to any Underwriter furnished in writing to the Company
by the Representatives on behalf of the Underwriters expressly for inclusion in
the Registration Statement, the preliminary prospectus or the Prospectus. This
indemnity will be in addition to any liability that each Underwriter might
otherwise have.

         (c) Any party that proposes to assert the right to be indemnified under
this Section 7 shall, promptly after receipt of notice of commencement of any
action against such party in respect of which a claim is to be made against an
indemnifying party or parties under this Section 7, notify each such
indemnifying party in writing of the commencement of such action, enclosing with
such notice a copy of all papers served, but the omission so to notify such
indemnifying party will not relieve it from any liability that it may have to
any indemnified party under the foregoing provisions of this Section 7 unless,
and only to the extent that, such omission results in the loss of substantive
rights or defenses by the indemnifying party. If any such action is brought
against any indemnified party and it notifies the indemnifying party of its
commencement, the indemnifying party will be entitled to participate in and, to
the extent that it elects by delivering written notice to the indemnified party
promptly after receiving notice of the commencement of the action from the
indemnified party, jointly with any other indemnifying party similarly notified,
to assume the defense of the action, with counsel reasonably satisfactory to the
indemnified party. After notice from the indemnifying party to the indemnified
party of its election to assume the defense, the indemnifying party will not be
liable to the indemnified party for any legal or other expenses except as
provided below and except for the reasonable costs of investigation subsequently
incurred by the indemnified party in connection with the defense. The
indemnified party will have the right to employ its own counsel in any such
action, but the fees, expenses and other charges of such counsel will be at the
expense of such indemnified party unless (i) the employment of counsel by the
indemnified party has been authorized in writing by the indemnifying party, (ii)
the indemnified party has reasonably concluded (based on advice of counsel) that
there may be legal defenses available to it or other indemnified parties that
are different from or in addition to those available to the indemnifying party,
(iii) a conflict or potential conflict exists (based on advice of counsel to the
indemnified party) between the indemnified party and the indemnifying party (in
which case the indemnifying party will not have the right to direct the defense
of such action on behalf of the indemnified party) or (iv) the indemnifying
party has not in fact employed counsel to assume the defense of such action
within a reasonable time after receiving notice of the commencement of the



                                       27
<PAGE>   28

action, in each of which cases the reasonable fees, disbursements and other
charges of counsel will be at the expense of the indemnifying party or parties.
It is understood that the indemnifying party or parties shall not, in connection
with any proceeding or related proceedings in the same jurisdiction, be liable
for the reasonable fees, disbursements and other charges of more than one
separate firm admitted to practice in such jurisdiction at any one time for all
such indemnified party or parties. All such fees, disbursements and other
charges will be reimbursed by the indemnifying party promptly as they are
incurred. Any indemnifying party will not be liable for any settlement of any
action or claim effected without its written consent (which consent will not be
unreasonably withheld).

         (d) If the indemnification provided for in this Section 7 is applicable
in accordance with its terms but for any reason is held to be unavailable to or
insufficient to hold harmless an indemnified party under paragraphs (a), (b) and
(c) of this Section 7 in respect of any losses, claims, liabilities, expenses
and damages referred to therein, then each applicable indemnifying party, in
lieu of indemnifying such indemnified party, shall contribute to the amount paid
or payable (including any investigative, legal and other expenses reasonably
incurred in connection with, and any amount paid in settlement of, any action,
suit or proceeding or any claim asserted, but after deducting any contribution
received by the Company or the Selling Stockholder from persons other than the
Underwriters, such as persons who control the Company within the meaning of the
Act, officers of the Company who signed the Registration Statement and directors
of the Company, who also may be liable for contribution) by such indemnified
party as a result of such losses, claims, liabilities, expenses and damages in
such proportion as shall be appropriate to reflect the relative benefits
received by the Company and the Selling Stockholder, on the one hand, and the
Underwriters, on the other hand. The relative benefits received by the Company
and the Selling Stockholder, on the one hand, and the Underwriters, on the other
hand, shall be deemed to be in the same proportion as the total net proceeds
from the offering (before deducting expenses) received by the Company and the
Selling Stockholder bear to the total underwriting discounts and commissions
received by the Underwriters, in each case as set forth in the table on the
cover page of the Prospectus. If, but only if, the allocation provided by the
foregoing sentence is not permitted by applicable law, the allocation of
contribution shall be made in such proportion as is appropriate to reflect not
only the relative benefits referred to in the foregoing sentence but also the
relative fault of the Company and the Selling Stockholder, on the one hand, and
the Underwriters, on the other hand, with respect to the statements or omissions
which resulted in such loss, claim, liability, expense or damage, or action in
respect thereof, as well as any other relevant equitable considerations with
respect to such offering. Such relative fault shall be determined by reference
to whether the untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact relates to information supplied by
the Company, the Selling Stockholder or the Representatives on behalf of the
Underwriters, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company, the Selling Stockholder and the Underwriters agree that it would
not be just and equitable if contributions pursuant to this Section 7(d) were to
be determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take into account the equitable considerations referred to herein. The amount
paid or payable by an indemnified party as a result of the loss, claim,
liability, expense or damage, or action in respect thereof, referred to above in
this Section 7(d) shall be deemed to include, for purposes of this Section 7(d),
any legal or other expenses reasonably incurred by such



                                       28
<PAGE>   29

indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 7(d), no Underwriter
shall be required to contribute any amount in excess of the underwriting
discounts received by it and no person found guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) will be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations to contribute as provided in
this Section 7(d) are several in proportion to their respective underwriting
obligations and not joint. For purposes of this Section 7(d), any person who
controls a party to this Agreement within the meaning of the Act will have the
same rights to contribution as that party, and each officer of the Company who
signed the Registration Statement will have the same rights to contribution as
the Company, subject in each case to the provisions hereof. Any party entitled
to contribution, promptly after receipt of notice of commencement of any action
against any such party in respect of which a claim for contribution may be made
under this Section 7(d), will notify any such party or parties from whom
contribution may be sought, but the omission so to notify will not relieve the
party or parties from whom contribution may be sought from any other obligation
it or they may have under this Section 7(d). No party will be liable for
contribution with respect to any action or claim settled without its written
consent (which consent will not be unreasonably withheld).

         (e) The indemnity and contribution agreements contained in this Section
7 and the representations and warranties of the Company and the Selling
Stockholder contained in this Agreement shall remain operative and in full force
and effect regardless of (i) any investigation made by or on behalf of the
Underwriters, (ii) acceptance of any of the Shares and payment therefor or (iii)
any termination of this Agreement.

         8. Reimbursement of Certain Expenses. In addition to its other
obligations under Section 7(a) of this Agreement, the Company hereby agrees to
reimburse on a quarterly basis the Underwriters for all reasonable legal and
other expenses incurred in connection with investigating or defending any claim,
action, investigation, inquiry or other proceeding arising out of or based upon,
in whole or in part, any statement or omission or alleged statement or omission,
or any inaccuracy in the representations and warranties of the Company or the
Selling Stockholder contained herein or failure of the Company or the Selling
Stockholder to perform its or his respective obligations hereunder or under law,
all as described in Section 7(a), notwithstanding the absence of a judicial
determination as to the propriety and enforceability of the obligations under
this Section 8 and the possibility that such payment might later be held to be
improper; provided, however, that, to the extent any such payment is ultimately
held to be improper, the persons receiving such payments shall promptly refund
them.

         9. Termination. The obligations of the several Underwriters under this
Agreement may be terminated at any time on or prior to the Closing Date (or,
with respect to the Option Shares, on or prior to the Option Closing Date), by
notice to the Company and the Selling Stockholder from the Representatives,
without liability on the part of any Underwriter to the Company if, prior to
delivery and payment for the Firm Shares or Option Shares, as the case may be,
in the sole judgment of the Representatives, (i) trading in any of the equity
securities of the Company shall have been suspended by the Commission or by The
Nasdaq Stock Market, (ii) trading in securities generally on The Nasdaq Stock
Market shall have been suspended or limited or minimum or maximum prices shall
have been generally established on such exchange, or additional material



                                       29
<PAGE>   30

governmental restrictions, not in force on the date of this Agreement, shall
have been imposed upon trading in securities generally by such exchange, by
order of the Commission or any court or other governmental authority, or by the
New York Stock Exchange, (iii) a general banking moratorium shall have been
declared by either Federal or Minnesota state authorities or (iv) any material
adverse change in the financial or securities markets in the United States or in
political, financial or economic conditions in the United States or any outbreak
or material escalation of hostilities or other calamity or crisis shall have
occurred, the effect of which is such as to make it, in the sole judgment of the
Representatives, impracticable or inadvisable to proceed with completion of the
public offering or the delivery of and payment for the Shares.

         If this Agreement is terminated pursuant to Section 10 hereof, neither
the Company nor the Selling Stockholder shall be under any liability to any
Underwriter except as provided in Sections 5(j), 7 and 8 hereof.

         10. Substitution of Underwriters. If any one or more of the
Underwriters shall fail or refuse to purchase any of the Firm Shares which it or
they have agreed to purchase hereunder, and the aggregate number of Firm Shares
which such defaulting Underwriter or Underwriters agreed but failed or refused
to purchase is not more than one-tenth of the aggregate number of Firm Shares,
the other Underwriters shall be obligated, severally, to purchase the Firm
Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase, in the proportions which the number of Firm Shares which
they have respectively agreed to purchase pursuant to Section 1 bears to the
aggregate number of Firm Shares which all such non-defaulting Underwriters have
so agreed to purchase, or in such other proportions as the Representatives may
specify; provided that in no event shall the maximum number of Firm Shares which
any Underwriter has become obligated to purchase pursuant to Section 1 be
increased pursuant to this Section 10 by more than one-ninth of such number of
Firm Shares without the prior written consent of such Underwriter. If any
Underwriter or Underwriters shall fail or refuse to purchase any Firm Shares and
the aggregate number of Firm Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase exceeds one-tenth of the
aggregate number of the Firm Shares and arrangements satisfactory to the
Representatives and the Company for the purchase of such Firm Shares are not
made within 48 hours after such default, this Agreement will terminate without
liability on the part of any non-defaulting Underwriter, the Company or the
Selling Stockholder for the purchase or sale of any Shares under this Agreement.
In any such case either the Representatives or the Company shall have the right
to postpone the Closing Date, but in no event for longer than seven days, in
order that the required changes, if any, in the Registration Statement and the
Prospectus or in any other documents or arrangements may be effected. The term
"Underwriter" includes any person substituted for a defaulting Underwriter. Any
action taken pursuant to this Section 10 shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

         11. Written Information. For all purposes under this Agreement each of
the Company and the Selling Stockholder understands and agrees with each of the
Underwriters that the following constitutes the only written information
furnished to the Company by or through the Representatives specifically for use
in preparation of the Registration Statement, any preliminary prospectus, the
Prospectus, or any amendment or supplement thereto: (i) the per share "Price to
Public" and per share "Underwriting Discounts and Commissions" set forth on the
cover page of



                                       30
<PAGE>   31

the Prospectus, (ii) the information relating to stabilization set forth in the
last paragraph on page two of the preliminary prospectus and the Prospectus, and
(iii) the information set forth under the caption "Underwriting" in the
preliminary prospectus and the Prospectus.

         12. Miscellaneous. Notice given pursuant to any of the provisions of
this Agreement shall be in writing and, unless otherwise specified, shall be
mailed or delivered (a) if to the Company or the Selling Stockholder, at the
office of the Company, 7423 Washington Avenue South, Minneapolis, Minnesota
55439, Attention: Greg R. Meland, with a copy to Messerli & Kramer P.A., 150
South Fifth Street, Suite 1800, Minneapolis, Minnesota 55402, Attention: Jeffrey
C. Robbins, Esq., or (b) if to the Underwriters, to the Representatives at the
offices of Needham & Company, Inc., 445 Park Avenue, New York, New York 10022,
Attention: Corporate Finance Department, with a copy to Kaplan, Strangis and
Kaplan, P.A., 5500 Norwest Center, 90 South Seventh Street, Minneapolis,
Minnesota 55402, Attention: James C. Melville, Esq. Any such notice shall be
effective only upon receipt. Any notice under such Section 9 or 10 may be made
by telex or telephone, but if so made shall be subsequently confirmed in
writing.

         This Agreement has been and is made solely for the benefit of the
several Underwriters, the Company, the Selling Stockholder and the controlling
persons, directors and officers referred to in Section 7, and their respective
successors and assigns, and no other person shall acquire or have any right
under or by virtue of this Agreement. The term "successors and assigns" as used
in this Agreement shall not include a purchaser, as such purchaser, of Shares
from any of the several Underwriters.

         Any action required or permitted to be made by the Representatives
under this Agreement may be taken by them jointly or by Needham & Company, Inc.

         This Agreement shall be governed by and construed in accordance with
the laws of the State of Minnesota applicable to contracts made and to be
performed entirely within such State.

         This Agreement may be signed in two or more counterparts with the same
effect as if the signatures thereto and hereto were upon the same instrument.

         In case any provision in this Agreement shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

         The Company and the Underwriters each hereby waive any right they may
have to a trial by jury in respect of any claim based upon or arising out of
this Agreement or the transactions contemplated hereby.

         The reimbursement, indemnification and contribution agreements
contained in this Agreement and the representations, warranties and covenants in
this Agreement shall remain in full force and effect regardless of (a) any
termination of this Agreement, (b) any investigation made by or on behalf of any
Underwriter or controlling person thereof, or by or on behalf of the Company or
its directors and officers and (c) delivery of and payment for the Shares under
this Agreement.

                    [AND DIRECTORS, OFFICERS AND STOCKHOLDERS
                  OF THE COMPANY WHO SHALL SIGN SUCH AGREEMENT]


         The undersigned is a holder of securities of Datalink Corporation, a
Minnesota corporation (the "Company"), and wishes to facilitate the public
offering of shares of the Common Stock (the "Common Stock") of the Company (the
"Offering"). The undersigned recognizes that such Offering will be of benefit to
the undersigned.

         In consideration of the foregoing and in order to induce you to act as
underwriters in connection with the Offering, the undersigned hereby agrees that
he, she or it will not, without the prior written approval of Needham & Company,
Inc., acting on its own behalf and/or on behalf of other representatives of the
underwriters, directly or indirectly, sell, contract to sell, make any short
sale, pledge, or otherwise dispose of, or enter into any hedging transaction
that is likely to result in a transfer of, any shares of Common Stock, options
to acquire shares of Common Stock or securities exchangeable for or convertible
into shares of Common Stock of the Company which he, she or it may own,
exclusive of any shares of Common Stock purchased in connection with the
Company's public offering for a period commencing as of the date hereof and
ending on the date which is one hundred eighty (180) days after the date of the
final Prospectus relating to the Offering. The undersigned confirms that he, she
or it understands that the underwriters and the Company will rely upon the
representations set forth in this Agreement in proceeding with the Offering. The
undersigned further confirms that the agreements of the undersigned are
irrevocable and shall be binding upon the undersigned's heirs, legal
representatives, successors and assigns. The undersigned agrees and consents to
the entry of stop transfer instructions with the Company's transfer agent
against the transfer of securities held by the undersigned except in compliance
with this Agreement.

         This Agreement shall be binding on the undersigned and his, her or its
respective successors, heirs, personal representatives and assigns.

                             DATALINK CORPORATION

   The undersigned, being the Chief Executive Officer of Datalink Corporation, a
Minnesota corporation (the "Company"), subject to the provisions of Chapter
302A of the Minnesota Statutes, known as the Minnesota Business Corporation
Act, does hereby certify that the Board of Directors and shareholders of the
Company adopted the following resolutions by joint action of the Board of
Directors and shareholders effective as of June 1, 1998:

                             AMENDED AND RESTATED
                          ARTICLES OF INCORPORATION

   RESOLVED: That the Articles of Incorporation of the Company be, and the same
hereby are, amended and restated, and the following Amended and Restated
Articles of Incorporation take the place of and supersede the existing Articles

entitled to vote shall be deemed to be present in person.

     Section 2.09. Vote Required. When a quorum is present or represented at any
meeting, the vote of the holders of a majority of the voting power of all shares
entitled to vote present in person or represented by proxy shall decide any
question brought before such meeting, unless the question is one that by express
provision of statute or of the Articles of Incorporation or of these Restated
By-Laws requires a different vote, in which case such express provision shall
govern the vote required.

     Section 2.10. Voting Rights. Except as may be otherwise required by statute
or the Articles of Incorporation or these Restated By-Laws, every shareholder of
record of the Corporation shall be entitled at each meeting of the shareholders
to one vote for each share of stock standing in his name on the books of the
Corporation.

     Section 2.11. Proxies. At any meeting of the shareholders, any shareholder
may be represented and vote by a proxy or proxies appointed by an instrument in
writing, signed by the shareholder, and filed with the Secretary at or before
the meeting. In addition, a shareholder of a publicly held corporation may cast
or authorize the casting of a vote by a proxy by transmitting to the Corporation
or the Corporation's duly authorized agent before the meeting, an appointment of
a proxy by means of a telegram, cablegram, or any other form of electronic
transmission, including telephonic transmission, whether or not accompanied by
written instructions of the shareholder. The electronic transmission must set
forth or be submitted with information from which it can be determined that the
appointment was authorized by the shareholder. If it is determined that a
telegram, cablegram, or other electronic transmission is valid, the inspectors
of election or, if there are no inspectors, the other persons making that
determination shall specify the information upon which they relied to make that
determination.

     An appointment of a proxy or proxies for shares held jointly by two or more
shareholders is valid if signed by any one of them, unless and until the
Corporation receives from any one of those shareholders written notice denying
the authority of such other person or persons to appoint a proxy or proxies or
appointing a different proxy or proxies, in which case no proxy shall be
appointed unless the instrument shall otherwise provide. If the proxies present
at the meeting are equally divided on an issue, the shares represented by such
proxies shall not be voted on such issue. No proxy shall be valid after the
expiration of eleven (11) months from the date of its execution unless coupled
with an interest or unless the person executing it specifies therein the length
of time for which it is to continue in force, which in no case shall exceed
three (3) years from the date of its execution. Subject to the above, any duly
executed proxy shall continue in full force and effect and shall not be revoked
unless written notice of its revocation or a duly executed proxy bearing a later
date is filed with the Secretary of the Corporation.

     Section 2.12. Action in Writing. Except as may be otherwise required by
statute or the Articles of Incorporation, any action required or permitted to be
taken at any meeting of shareholders of the Corporation may be taken without a
meeting, without prior notice, and without a vote, if a consent in writing,
setting forth the action so taken, shall be signed by the holders of outstanding
stock that would be entitled to vote thereon at a meeting of the shareholders.

     Section 2.13. Closing of Books; Record Date. The Board of Directors may
fix, or authorize an officer to fix, a date, not exceeding sixty (60) days
preceding the date of any meeting of the shareholders of the Corporation, as a
record date for the determination of the shareholders of record on the date so
fixed or their legal representatives shall be entitled to notice of and to vote
at such meeting, notwithstanding any transfer of shares on the books of the
Corporation against the transfer of shares during the whole or any part of such
period. If the Board of Directors or an authorized officer fails to fix such a
record date, the record date shall be the twentieth (20th) day preceding the
date of such meeting.

                             ARTICLE III. DIRECTORS

     Section 3.01. General Powers. The business of the Corporation shall be
managed by its Board of Directors, which may exercise all such powers of the
Corporation and do all such lawful acts and things as are by statute or by the
Articles of Incorporation or by these Restated By-Laws directed or required to
be exercised or done by the shareholders.

     Section 3.02. Number and Qualification. The number of Directors that shall

Directors may not decrease the number of Directors below the number last
designated by the shareholders. Directors need not be shareholders. Each of the
Directors shall hold office until the next succeeding regular meeting of
shareholders and until his successor shall have been duly elected and qualified,
or until his earlier resignation or removal from office as hereinafter provided.

     Section 3.03. Vacancies. In the event that any member of the Board of
Directors shall resign, die, be removed from office, become disqualified, or
refuse to act during his term of office, or any vacancy or vacancies in the
Board of Directors shall occur for any other reason, such vacancy or vacancies
may be filled by a majority vote of the remaining members of the Board of
Directors, although less than a quorum, the provisions of Section 3.04-e hereof

The voting by the shareholders to fill such vacancy or vacancies shall be
conducted as provided in the Articles of Incorporation and these Restated
By-Laws. When one or more Directors shall give notice of his or their
resignation to the Board, effective at a future date, the Board shall have power
to fill such vacancy or vacancies to take effect when such resignation or
resignations shall become effective. Each Director elected to hold office as
provided in this Section 3.03 shall hold office until the next succeeding
regular meeting of the shareholders and until his successor shall have been
elected and qualified, or until his earlier resignation or removal from office
as hereinafter provided.

     Section 3.04. Meetings.

          Section  3.04-a.  Place of  Meetings.  The Board of  Directors of the
     Corporation may hold meetings,  both regular and special, either within or
     without the State of Minnesota.

          Section 3.04-b. Regular Meetings. As soon as practicable after each
     regular election of Directors, the Board of Directors shall meet at the
     registered office of the Corporation, or at such other place within or
     without the State of Minnesota as may be designated by the Board of
     Directors, for the purpose of electing the officers of the Corporation and
     for the transaction of such other business as shall come before the
     meeting. Other regular meetings of the Board of Directors may be held
     without notice at such time and place within and without the State of
     Minnesota as shall from time to time be determined by resolution of the
     Board of Directors.

          Section 3.04-c. Special Meetings. Special meetings of the Board of
     Directors may be called by the Chief Executive Officer or Secretary or by
     one or more Directors and shall be held at such time and place as shall be
     designated in the notice of such meeting.

          Section 3.04-d.  Notice. Notice of a special meeting shall be given to
     each  Director at least 24 hours before the time of the meeting, or at the
     earliest time possible thereafter, but prior

                                       4


<PAGE>   9


     to such meeting, if it is impractical to give such notice 24 hours in
     advance. Notice may be given by any means calculated to apprise the
     Directors of the time, place and subject matter of the special meeting.
     Notice by mail shall be deemed to be given at the time when the same shall
     be mailed, such mailing to take place at least three (3) business days
     prior to such meeting. Whenever any provision of law, the Articles of
     Incorporation, or the Restated By-Laws require notice to be given, any
     Director may, in writing, either before or after the meeting, waive notice
     thereof. Without notice, any Director, by his attendance at and
     participation in the action taken at the meeting, shall be deemed to have
     waived notice thereof.

          Section 3.04-e. Quorum; Voting Requirements; Adjournment. A majority
     of the Board of Directors then in office shall be necessary to constitute a
     quorum for the transaction of business, and the act of a majority of the
     Directors present at any meeting at which a quorum is present shall be the
     act of the Board of Directors, except as may be otherwise specifically
     provided by statute or by the Articles of Incorporation or these Restated
     By-Laws.

          If a quorum shall not be present at any meeting of the Board of
     Directors, the Directors present thereat may adjourn the meeting to another
     time or place, and no notice as to such adjourned meeting need be given
     other than by announcement at the meeting at which such adjournment is
     taken. If a quorum is present at the call of a meeting, the Directors may
     continue to transact business until adjournment notwithstanding the
     withdrawal of enough Directors to leave less than a quorum.

          Section 3.04-f. Organization of Meetings. At all meetings of the Board
     of Directors, the Chair of the Board, if appointed, or in his absence, the
     Chief Executive Officer, or in his absence, any Director appointed by the
     Chief Executive Officer, shall preside, and the Secretary, or in his
     absence, any person appointed by the Chief Executive Officer, shall act as
     Secretary.

          Section 3.04-g. Action in Writing. Except as may be otherwise required
     by statute or the Articles of Incorporation, any action required or
     permitted to be taken at any meeting of the Board of Directors of the
     Corporation may be taken without a meeting, without prior notice, and
     without a vote, if a consent in writing, setting forth the action so taken,
     shall be signed by the number of Directors that would be necessary to
     authorize or take such action at a meeting at which all Directors entitled
     to vote thereon were present and voted. Prompt notice of the taking of the
     corporate action without a meeting by less than unanimous consent shall be
     given to those Directors who have not consented in writing.

          Section 3.04-h. Absent Directors. A Director may give advance written
     consent or opposition to a proposal to be acted on at a meeting of the
     Board of Directors. Such advance written consent or opposition shall be
     ineffective unless the writing is delivered to the Chief Executive Officer
     or Secretary of the Corporation prior to the meeting at which such proposal
     is to be considered. If the Director is not present at the meeting, consent
     or opposition to a proposal does not constitute presence for purposes of
     determining the existence of a quorum, but such consent or opposition shall
     be counted as a vote in favor of or against the proposal and shall be
     entered in the minutes or other record of action at the meeting, if the
     proposal acted on at the meeting is substantially the same or has
     substantially the same effect as the proposal to which the Director has
     consented or objected, such substantial similarity to be determined in the
     sole judgment of the presiding officer at the meeting.

     Executive Committee consisting of two (2) or more Directors of the
     Corporation. Such Committee may meet at stated times or on notice by any
     Committee member to all other members. The Executive Committee, to the
     extent determined by such action of the Board, shall have and exercise the
     authority of the Board and the management of the business of the
     Corporation. Any such Executive Committee shall act only in the interval
     between meetings of the Board and shall be subject at all times to the

     it is in the best interests of the Corporation to pursue a particular legal
     right or remedy of the Corporation or whether to cause the dismissal or
     discontinuance of a particular proceeding that seeks to assert a right or
     remedy on behalf of the Corporation. For purposes of this Section 3.05-b, a

     once established, is not subject to the direction or control of, or
     termination by, the Board of Directors. A vacancy on the Committee may be
     filled by a majority vote of the remaining members. The good faith
     determination of the Committee is binding upon the Corporation and its
     Directors, officers, and shareholders. The Committee shall be dissolved
     upon the issuance of a final written report of its determinations to the
     Board of Directors.

     other committees from time to time (including a Compensation and an Audit
     Committee), making such regulations as it deems advisable with respect to
     the membership, authority, and procedures of such committees.

          Section  3.05-d.  Limitations  on  Authority.  No  committees  of  the
     Corporation shall have authority as to any of the following matters:

          (a)  The  submission  to  shareholders  of  any  action  as  to  which
               shareholders' authorization is required by law;

          (b)  The filling of vacancies on the Board of Directors or on any
               committees;

          (c)  The fixing of compensation of any Director for serving on the
               Board or on any committee;

          (d)  The amendment or repeal of these Restated By-Laws or the adoption
               of new Bylaws; or

          (e)  The amendment or repeal of any resolution of the Board, which by
               its terms shall not be so amendable or repealable.

     member of a duly constituted committee of the Board of Directors may
     participate in any meeting of the Board of Directors or of any duly
     constituted committee thereof my means of a conference telephone or other
     comparable communication technique whereby all persons participating in
     such a meeting can hear and communicate with each other. For the purpose of
     establishing a quorum and taking any action at such a meeting, the members
     participating in such a meeting pursuant to this Section 3.06 shall be
     deemed present in person at such meeting.

          Section 3.07. Compensation. Directors may be paid their expenses, if
     any, of attendance at each meeting of the Board of Directors. Directors who
     are not also salaried officers may be paid a fixed sum for attendance at
     each meeting of the Board of Directors. Nothing herein contained shall
     preclude any Director from serving the Corporation in any other capacity
     and receiving compensation therefor. Members of special or standing
     committees may be allowed like compensation for attending committee
     meetings.

          Section 3.08. Limitation of Directors' Liabilities. A Director shall
     not be liable to the Corporation or its shareholders for dividends
     illegally declared, distributions illegally made to shareholders, or any
     other actions taken in good faith reliance upon financial statements of the
     Corporation represented to him to be correct by the Chief Executive Officer
     of the Corporation or the officer having charge of its books of account or
     certified by an independent or certified public accountant to fairly
     reflect the financial condition of the Corporation; nor shall he be liable
     if in good faith in determining the amount available for dividends or
     distributions the Board values the assets in a manner allowable under
     applicable law.

     entire Board of Directors or any individual Director may be removed from
     office with or without cause by a vote of the shareholders holding a
     majority of the shares entitled to vote at an election of the Directors.

                       ARTICLE V. CERTIFICATES FOR SHARES

     Section 5.01. Issuance of Shares and Fractional Shares. The Board of
Directors is authorized to issue shares and fractional shares of stock of the
Corporation up to the full amount authorized by the Articles of Incorporation in
such amounts as may be determined by the Board of Directors and as permitted by
law. No shares shall be allotted except in consideration of cash or other
property, tangible or intangible, received or to be received under a written
agreement by the Corporation, or services rendered or to be rendered under a
written agreement to the Corporation, or an amount transferred from surplus to
stated capital upon a share dividend. At the time of each such allotment of
shares, the Board of Directors shall state by resolution its determination of
the fair market value to the Corporation in monetary terms of any consideration
other than cash for which shares are allotted. The amount of consideration to be
received in cash or otherwise shall not be less than the par value of the shares
so allotted nor less than the stated capital to be represented by shares without
par value so allotted.

represented by a certificate or shall be uncertificated. Certificates shall be
signed by the Chief Executive Officer, a Vice President, the Chief Financial
Officer or an Assistant Treasurer, or the Secretary or an Assistant Secretary of

in the Corporation. If the Corporation shall be authorized to issue more than
one class of stock or more than one series of any class, the designations,
preferences, and relative, participating, optional, or other special rights of
the various classes of stock or series thereof and the qualifications,

authority of the Board of Directors to determine the relative rights and
preferences of subsequent classes or series, shall be set forth in full on the
face or back of the certificate which the Corporation shall issue to represent
such stock, or, in lieu thereof, such certificate shall contain a statement that
the stock is, or may be, subject to certain rights, preferences, or restrictions
and that a statement of the same will be furnished without charge by the
Corporation upon request by any shareholder. Certificates representing the
shares of the capital stock of the Corporation shall be in such form not
inconsistent with law or the Articles of Incorporation or these Restated By-Laws
as shall be determined by the Board of Directors.

<PAGE>   14




     Section 5.03. Facsimile Signatures. Whenever any certificate is
countersigned or otherwise authenticated by a transfer agent, transfer clerk, or
registrar, then a facsimile of the signatures of the officers or agents of the
Corporation may be printed or lithographed upon such certificate in lieu of the
actual signatures. In case any officer or officers who shall have signed, or
whose facsimile signature shall have been used on, any such certificate or
certificates shall cease to be such officer or officers of the Corporation,
whether because of death, resignation, or otherwise, before such certificate or
certificates shall have been delivered by the Corporation, such certificate or
certificates may nevertheless be adopted by the Corporation and be signed and
delivered as though the person or persons who signed such certificate or
certificates, or whose facsimile signature or signatures shall have been used
thereon, had not ceased to be the officer or officers of the Corporation.

     Section 5.04. Lost, Stolen, or Destroyed Certificates. The Board of
Directors may direct a new certificate or new certificates or uncertificated
shares to be issued in place of a certificate or certificates previously issued
by the Corporation alleged to have been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the person claiming the certificate of
stock to be lost, stolen or destroyed. When authorizing such issue of a new
certificate or new certificates or uncertificated shares, the Board of Directors
may, in its discretion and as a condition precedent to the issuance thereof,
require the owner of such lost, stolen or destroyed certificate or certificates,
or his legal representative, to advertise the same in such manner as it shall
require and/or to give the Corporation a bond in such sum as it may direct as
indemnity against any claim that may be made against the Corporation with
respect to the certificate alleged to have been lost, stolen or destroyed.

     Section 5.05. Transfers of Stock. Upon surrender to the Corporation or the
transfer agent of the Corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignation or authority to
transfer, it shall be the duty of the Corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate and record the

resolution duly adopted, establish conditions upon the transfer of shares of
stock to be issued by the Corporation, and the purchasers of such shares shall
be deemed to have accepted such conditions on transfer upon the receipt of the
certificate representing such shares, provided that the restrictions shall be

notified thereof.

     Section 5.06. Uncertificated Shares. Unless prohibited by the Articles of
Incorporation or these Restated By-Laws, some or all of any or all classes and
series of the Corporation's shares may be uncertificated shares. Upon receipt of
proper transfer instructions from the registered owner of uncertificated shares
such uncertificated shares shall be canceled and issuance of new equivalent

entitled thereto and the transaction shall be recorded upon the books of the
Corporation. Within a reasonable time after the issuance or transfer of
uncertificated shares, the Corporation shall send to the new shareholder the

Corporation becomes a publicly held corporation which adopts, in compliance with

                        treated as Shares owned by the Employee; or

                        (iii) Upon the happening of any event or the
                        consummation of any transaction which causes the entity
                        of which the Participant is an Employee to cease being
                        an Employer as defined in Section 2.10.

         (e) A Participant shall cease to be a Participant, but shall be
         eligible to participate in this Plan with respect to any subsequent
         Offering, if he or she notifies the Company in writing of his or her
         desire to withdraw from participation in this Plan.

accordance with Sections 3.2(d) and (e) shall have the rights provided in

                             PAYROLL DEDUCTIONS

4.1 PAYROLL DEDUCTION AUTHORIZATION. An Employee may contribute to this Plan
only by means of payroll deductions. Other than as set forth in Section

4.2 AMOUNT OF DEDUCTIONS. A Participant may specify the rate at which he or she
desires to contribute to this Plan, which rate shall not be less than one
percent (1%) and not more than ten percent (10%) of the Participant's
Compensation during each pay period in the Offering. For administrative
convenience, the Company may round off Participant contributions to an even
dollar amount, such as the nearest $1.00 increment. A Participant's particular
election shall apply during any period of continuous participation in the Plan,
unless modified or discontinued as provided in Section 4.5 or as otherwise
provided in this Plan. If a payroll deduction cannot be made in whole or in part
because the Participant's pay for the period in question is insufficient to fund
the deduction after having first withheld all other amounts deductible from his
or her pay, the amount that was not withheld cannot be made up by the
Participant nor will it be withheld from subsequent pay checks.

4.3 COMMENCEMENT OF DEDUCTIONS. Payroll deductions for a Participant shall
commence on the Enrollment Date of the Offering for which his or her Payroll
Deduction Authorization Form is effective and shall continue for future
Offerings, unless modified or discontinued as provided in Section 4.5 or as
otherwise provided in this Plan.

4.4 ACCOUNTS.  All payroll deductions made for a Participant shall be credited 
to his or her Account.

4.5 MODIFICATION OF AUTHORIZED DEDUCTIONS.

         (a) A Participant may at any time discontinue his or her payroll
         deductions, effective for all subsequent payroll periods, by completing
         an amended Payroll Deduction Authorization Form and filing it with his
         or her payroll office. At such time, the Participant may elect to
         retain previous payroll deductions in his or her Account and continue
         participation in this Plan for subsequent offering or to withdraw from
         this Plan pursuant to Section 6.4.

         (b) For purposes of this Section 4.5, an amended Payroll Deduction
         Authorization Form shall be effective for a specific pay period when
         filed 15 days prior to the start of such period.

6.4, the Company shall purchase, as of the Purchase Date, the number of Shares
determined pursuant to this Article V.

limitations of Article VI, apply the amount credited to each Participant's
Account to the purchase of as many full Shares that may be purchased with such

Participant. Payment for Shares purchased under this Plan will be made only
through payroll withholding in accordance with Article IV.

lower of:

         (a)  Eighty-five  percent  (85%) of the fair market value of the 
         Shares on the  Enrollment  Date of the Offering; or

                                       5

<PAGE>   6

         (b)  Eighty-five  percent  (85%) of the fair market value of the 
         Shares on any Purchase  Date of the Offering.

5.4 FAIR MARKET VALUE.

         (a) The fair market value of the Shares on any date shall be equal to
         the bid price of the Company's Common Stock at the close of business on
         the Valuation Date, as reported on the Nasdaq National Market system or
         such other quotation system that supersedes it.

         (b) If (a) is not applicable, the fair market value of the Shares shall
         be determined by the Plan Administrator in good faith. Such
         determination shall be conclusive and binding on all persons.

5.5 UNUSED CONTRIBUTIONS.

         (a) Subject to the limitations of Sections 3.2(e) and 11.3, a

         next occurring Enrollment Date following such withdrawal by
         re-enrolling in such subsequent Offering pursuant to Section
         3.2(c)(ii).

         (b) Provided that a Participant's Employment with the Company has not
         terminated and the Participant has not withdrawn from the Plan pursuant
         to Article VI, and subject to Section 7.1(b), any amount credited to a
         Participant's Account and remaining therein immediately after a
         Purchase Date shall be carried forward in such Participant's Account
         for application on the next succeeding Purchase Date, subject to the
         notice provisions of Section 5.1.

for any reason other than as set forth in Section 6.2, the payroll deductions
credited to such Participant's Account shall be returned to the Participant.
Except as provided in Section 6.2, a Participant shall have no right under this
Plan to acquire Shares upon or after termination of his or her Employment.

6.2 TERMINATION UPON DEATH, RETIREMENT OR DISABILITY WITHIN THREE MONTHS OF
PURCHASE DATE. Upon termination of the Participant's Employment within the
three-month period preceding a Purchase Date because of his or her death,
Retirement or Disability, the payroll deductions credited to his or her Account
shall be used to purchase Shares as provided in Article V on the next Purchase
Date. Any remaining balance in the Participant's Account shall be returned to
him or her or, in the case of death, any Shares purchased and any remaining
balance shall be transferred to the deceased Participant's Beneficiary, or if
none, to his or her estate.

6.4 WITHDRAWAL. A Participant whose Employment with the Company is continuing
(i.e., has not been terminated as described in Sections 6.1 and 6.2) may elect
to withdraw the entire amount credited to his or her Account and cease further
participation at any time by giving written notice to the Company at least 15
days prior to the next Purchase Date. The amount withdrawn shall be paid to the
Participant promptly after receipt of proper notice of withdrawal and no further
payroll deductions shall be made from his or her compensation unless and until a

                                 ARTICLE VII
                       SHARES PURCHASED UNDER THE PLAN


7.1 SOURCE AND LIMITATION OF SHARES.

         (a) The Company has reserved for sale under this Plan 250,000  
         shares of its Common  Stock, subject to adjustment  upon changes in  
         capitalization  of the Company as provided in Section 9.2.  Shares
         sold under this Plan shall be newly issued Shares.

         (b) If there is an insufficient number of Shares to permit the full
         exercise of all existing rights to purchase Shares, or if the legal
         obligations of the Company prohibit the issuance of all Shares
         purchasable upon the full exercise of such rights, the Plan
         Administrator shall make a pro rata allocation of the Shares remaining
         available in as nearly a uniform and equitable manner as possible,
         based pro rata on the aggregate amounts then credited to each
         Participant's Account. In such event, payroll deductions to be made
         shall be reduced accordingly and the Plan Administrator shall give
         written notice of such reduction to each Participant affected thereby.
         Any amount remaining in a Participant's Account immediately after all
         available Shares have been purchased will be promptly remitted to such
         Participant. Determination by the Plan Administrator in this regard
         shall be final, binding and conclusive on all persons. No deductions
         shall be permitted under this Plan at any time when no Shares are
         available.

7.2 DELIVERY OF SHARES. As promptly as practicable after the Purchase Date, the
Company shall deliver to the Participant the full Shares purchased with his or
her payroll deductions.

7.3 INTEREST IN SHARES. The rights to purchase Shares granted pursuant to this
Plan will in all respects be subject to the terms and conditions of this Plan,
as interpreted by the Plan Administrator from time to time. The Participant
shall have no interest in Shares purchasable under this Plan until payment for
the Shares has been completed at the close of business on the relevant Purchase
Date. This Plan provides only an unfunded, unsecured promise by the Employer to
pay money or property in the future. Except with respect to the Shares purchased
on a Purchase Date, an Employee choosing to participate in this Plan shall have
no greater rights than an unsecured creditor of the Company. After the purchase
of the Shares, the Participant shall be entitled to all rights of a stockholder
of the Company.

                                ARTICLE VIII
                             PLAN ADMINISTRATION

Committee, if any, and otherwise by the Board of Directors. The Plan
Administrator shall be vested with full authority to make, administer and
interpret all rules and regulations applicable to this Plan as it deems
necessary for

                                       7

purposes of administering this Plan. This Plan is intended to qualify for the
"Stock Purchase Plan" exemption of Rule 16b-3 of the regulations promulgated
under the Securities Exchange Act. Any determination, decision or action of the
Plan Administrator with respect to the construction, interpretation,
administration or application of this Plan shall be final, conclusive and
binding upon all Participants and any and all persons claiming benefits under
this Plan. The provisions of this Plan shall also be construed so as to extend
and limit participation in a manner consistent with the requirements of Section
423 of the Code.

                                 ARTICLE IX
                   CHANGES IN CAPITALIZATION, MERGER, ETC.

9.1 RIGHTS OF THE COMPANY. The grant of a right to purchase Shares pursuant to
this Plan shall not affect in any way the right or power of the Company to make
adjustments, reclassifications, reorganizations or other changes of its capital
or business structure or to merge or to consolidate or to dissolve, liquidate or
transfer all or any part of its divisions, subsidiaries, business or assets.

9.2 RECAPITALIZATIONS. Subject to any required action by the stockholders, the
number of Shares covered by this Plan as provided in Section 7.1 and the price
per share shall be proportionately adjusted for any increase or decrease in the
number of issued Shares of the Company resulting from a subdivision or
consolidation of Shares or the payment of a stock dividend (but only on the
Shares) or any other increase or decrease in the number of such Shares affected
without receipt of consideration by the Company; but only for such increase or
decrease occurring after the initial closing of the Company's initial public
offering of Common Stock.

9.3 CONSOLIDATION OR MERGER. In the event of the consolidation or merger of the
Employer with or into any other business entity, or the sale by the Employer of
substantially all of its assets, the successor may continue this Plan by
adopting the same by resolution of its board of directors or agreement of its
partners or proprietors. If, within 90 days after the effective date of a
consolidation, merger or sale of assets, the successor corporation, partnership
or proprietorship does not adopt this Plan, this Plan shall be terminated and
all amounts held by this Plan under the Participants' Account shall be returned
to the Participants.

                          TERMINATION OF EMPLOYMENT
 
10.1 VACATION, LEAVE OR LAYOFF. A person's Employment shall not terminate on
account of an authorized leave of absence, sick leave or vacation, or on account
of a military leave described in Section 10.2, or a direct transfer between
Employers. Failure to return to work upon expiration of any leave of absence,
sick leave or vacation shall be considered a resignation effective as of the
expiration of such leave of absence, sick leave or vacation.

10.2 MILITARY LEAVE. Any Employee who leaves the Employer directly to perform
services in the Armed Forces of the United States or in the United States Public
Health Service under conditions entitling the Employee to re-employment rights
provided by the laws of the United States, shall be on military leave. An
Employee's military leave shall expire if the Employee voluntarily resigns from
the Employer during the leave or if he or she fails to make application for
re-employment within the period specified by such law for the preservation of
employment rights. In such event, the individual's employment shall terminate by
resignation on the day the military leave expires.

11.1 AMENDMENT AND TERMINATION.

         (a) The Board of Directors of the Company may at any time amend this
         Plan. An amendment shall require the approval of the Stockholders of
         the Company if the amendment would permit the sale of more Shares than
         are authorized under Section 7.1, or the amendment otherwise requires
         shareholder approval under Section 423 of the Code or Rule 16b of the
         Securities Exchange Act.

         (b) This Plan is intended to be a permanent program, but an Employer
         shall have the right at any time to declare this Plan terminated
         completely as to it or as to any of the Employer's divisions,
         facilities, operational units or job classifications. Upon such
         termination, amounts credited to the Accounts of Participants with
         respect to whom the Plan has been terminated shall be returned to such
         Participants.

11.2 NON-TRANSFERABILITY. Neither payroll deductions credited to a Participant's
Account nor any rights with regard to the purchase of Shares under this Plan may
be assigned, transferred, pledged or otherwise disposed of in any way by the
Participant except as provided in Section 6.2, and any attempted assignment,
transfer, pledge, or other disposition shall be null and void. The Company may
treat any such act as an election to withdraw funds in accordance with Section
6.4.

11.3 LIMITATION ON PURCHASE. No Participant may obtain a right to purchase
Shares under this Plan if such right would, upon immediate exercise for shares,
result in that Participant:

         (a) owning stock possessing five percent (5%) or more of the total
         combined voting power or value of all classes of stock of the Company
         or its Subsidiaries as determined under Section 423(b) of the Code; or

         (b) obtain rights to purchase stock under this Plan or under any other
         employee stock purchase plan of the Company or any of its Subsidiaries
         or its parents that will accrue at a rate which exceeds the maximum
         fair market value of the stock as permitted to accrue by 
         Section 403(b)(8) of the Code (determined as of the Enrollment Date)
         for each calendar year in which he or she is a Participant;

this Plan may be used by the Company for any corporate purposes and the Company
shall not be obligated to segregate the payroll deductions.

11.5 EXPENSES. All expenses of administering this Plan shall be borne bythe
Company and its Subsidiaries.

11.6 NO INTEREST. No Participant shall be entitled, at any time, to any payment
or credit for interest with respect to or on the payroll deductions contemplated

<PAGE>   10

any other registration or qualification of the Shares under any federal or state
law or the obtaining of the consent or approval of any governmental regulatory
body which the Company shall determine, in its sole discretion, is necessary or
desirable as a condition to, or in connection with, the offering or the issue or
purchase of the Shares covered thereby. The Company shall make every reasonable
effort to effect such registration or qualification or to obtain such consent or
approval.

11.8 PLAN NOT A CONTRACT OF EMPLOYMENT. This Plan is strictly a voluntary
undertaking on the part of the Employer and shall not constitute a contract
between the Employer and any Employee, or consideration for an inducement or a
condition of, the employment of an Employee. Except as otherwise required by law
or any applicable collective bargaining agreement, nothing contained in this
Plan shall give any Employee the right to be retained in the service of the
Employer or to interfere with or restrict the right of the Employer, which is
hereby expressly reserved, to discharge or retire any Employee at any time, with
or without cause and with or without notice. Except as otherwise required by
law, inclusion under this Plan will not give any Employee any right or claim to
any benefit hereunder except to the extent such right has specifically become
fixed under the terms of the Plan.The doctrine of substantial performance shall
have no application to any Employee, Participant or Beneficiary. Each condition
and provision, including numerical items, has been carefully considered and
constitutes the minimum limit on performance which will give rise to the
applicable right.

11.9 NOTICE. All notices or other communications by a Participant to the Company
under or in connection with this Plan shall be deemed to have been duly given
when received by the Plan Administrator. Any notice required by this Plan to be
received by the Company prior to an Enrollment Date, payroll period or other
specified date, and received by the Plan Administrator subsequent to such date,
shall be effective on the next occurring Enrollment Date, payroll period or
other specified date to which such notice applies.

in accordance with the Code, and the rights of Participants, former
Participants, Beneficiaries and all other persons shall be determined in
accordance with it. To the extent that state law is applicable, however, the
laws of the State of Minnesota shall apply.

11.11 PLURALS. Where the context so indicates, the singular shall include the
plural and vice versa.


11.12 TITLES. Titles of Articles and Sections are provided herein for
convenience only and are not to serve as the basis for interpretation or
construction of this Plan.

11.13 REFERENCES. Unless the context clearly indicates to the contrary,
reference to a Plan provision, statute, regulation or document shall be
construed as referring to any subsequently enacted, adopted or executed
counterpart.

provided, however, that no Option shall be exercisable later than the tenth
(10th) anniversary date of its grant.

6.5.     EXERCISE OF OPTIONS.  Options granted under this Article 6 shall be
exercisable at such times and be subject to such restrictions and conditions as
the Board shall in each instance approve, which need not be the same for each
grant or for each Participant.

6.6.     PAYMENT.  Options granted under this Article 6 shall be exercised by 
the delivery of a written notice of exercise to the Company, setting
forth the number of Shares with respect to which the Option is to be exercised,
accompanied by full payment for the Shares.  The Option Price upon exercise of
any Option shall be payable to the Company in full either: (a) in cash or its
equivalent, or (b) by tendering previously acquired Shares having an aggregate
Fair Market Value at the time of exercise equal to the total Option Price
(provided that the Shares which are tendered must have been held by the
Participant for at least six (6) months prior to their tender to satisfy the
Option Price), or (c) by a combination of (a) and (b).  The Board also may
allow cashless exercise as permitted under Federal Reserve Board's Regulation
T, subject to applicable securities law restrictions, or by any other means
which the Board determines to be consistent with the Plan's purpose and
applicable law.  Subject to any governing rules or regulations, as soon as

payment, the Company shall deliver to the Participant, in the Participant's
name, Share certificates in an appropriate amount based upon the number of
Shares purchased under the Option(s).

6.7      RESTRICTIONS ON SHARE TRANSFERABILITY.  The Board may impose such
restrictions on any Shares acquired pursuant to the exercise of an Option
granted under this Article 6 as it may deem advisable, including, without

listed and/or traded, and under any blue sky or state securities laws
applicable to such Shares.

stockholders' meeting and on the date of each subsequent annual stockholders'
meeting occurring while the Plan remains in effect each Director then serving
on the Board on the date of any such meeting shall be granted Nonqualified
Stock Options to purchase 3,000 Shares.  These Nonqualified Stock Options shall
be exercisable commencing one year after the date of grant; provided, however,
that if a Director fails to serve until the annual stockholders' meeting
immediately succeeding a grant of such Options, the number of Shares that may
be purchased by such Director shall be determined by multiplying 3,000 by a
fraction (i) the numerator of which is the number of days between the date such
Options were granted and the date the Director ceased




                                      7
<PAGE>   8

serving on the Board and (ii) the denominator of which is the number of days
between the date such Options were granted and the date of the annual
stockholders' meeting immediately succeeding the date of grant.  The Option
Price of each Nonqualified Stock Option granted pursuant to this Section 6.8
shall be the Fair Market Value of a Share on the date of grant.  These
Nonqualified Stock Options will expire ten years after the date of grant.

or any combination of these forms of SAR.  The Board shall have complete
discretion in determining the number of SARs granted to each Participant
(subject to Article 4 herein) and, consistent with the provisions of the Plan,
in determining the terms and conditions pertaining to such SARs.  The grant
price of a Freestanding SAR shall equal the Fair Market Value of a Share on the
date of grant of the SAR.  The grant price of Tandem SARs shall equal the
Option Price of the related Option.

7.2.     EXERCISE OF TANDEM SARs.  Tandem SARs may be exercised for all or part
of the Shares subject to the related Option upon the surrender of the right to
exercise the equivalent portion of the related Option.  A Tandem SAR may be
exercised only with respect to the Shares for which its related Option is then
exercisable.  Notwithstanding any other provision of this Plan to the contrary,
with respect to a Tandem SAR granted in connection with an ISO: (i) the Tandem
SAR will expire no later than the expiration of the underlying ISO; (ii) the
value of the payout with respect to the Tandem SAR may be for no more than one
hundred percent (100%) of the difference between the Option Price of the
underlying ISO and the Fair Market Value of the Shares subject to the
underlying ISO at the time the Tandem SAR is exercised; and (iii) the Tandem
SAR may be exercised only when the Fair Market Value of the Shares subject to
the ISO exceeds the Option Price of the ISO.

7.3.     EXERCISE OF FREESTANDING SARs.  Freestanding SARs may be exercised
upon whatever terms and conditions the Board, in its sole discretion, imposes
upon them.

7.4.     SAR AGREEMENT.  Each SAR grant shall be evidenced by an Award
Agreement that shall specify the grant price, the term of the SAR, and such
other provisions as the Board shall determine.

7.5.     TERM OF SARs.  The term of an SAR granted under the Plan shall be
determined by the Board, in its sole discretion; provided, however, that such
term shall not exceed ten (10) years.

7.6.     PAYMENT OF SAR AMOUNT.  Upon exercise of an SAR, a Participant shall
be entitled to receive payment from the Company in an amount determined by
multiplying:

         (a)     The difference between the Fair Market Value of a Share on the
date of exercise over the grant price; by



                                      8

<PAGE>   9


         (b)     The number of Shares with respect to which the SAR is
exercised.

At the discretion of the Board, the payment upon SAR exercise may be in cash,
in Shares of equivalent value, or in some combination thereof.  The Board's
determination regarding the form of SAR payout shall be set forth in the Award
Agreement pertaining to the grant of the SAR.

evidenced by a Restricted Stock Award Agreement that shall specify the
Period(s) of Restriction, the number of Shares of Restricted Stock granted, and

8.3.     OTHER RESTRICTIONS.  Subject to Article 12 herein, the Board shall
impose such other conditions and/or restrictions on any Shares of Restricted
Stock granted pursuant to the Plan as it may deem advisable including, without
limitation, a requirement that Participants pay a stipulated purchase price for
each Share of Restricted Stock, restrictions based upon the achievement of
specific performance goals (Company-wide, divisional, and/or individual),
time-based restrictions on vesting following the attainment of the performance
goals, and/or restrictions under applicable federal or state securities laws.
The Company may retain the certificates representing Shares of Restricted Stock
in the Company's possession until such time as all conditions and/or
restrictions applicable to such Shares have been satisfied.  Except as
otherwise provided in this Article 8, Shares of Restricted Stock covered by
each Restricted Stock grant made under the Plan shall become freely
transferable by the Participant after the last day of the applicable Period of
Restriction.

8.4.     VOTING RIGHTS.  Participants holding Shares of Restricted Stock
granted hereunder may be granted the right to exercise full voting rights with
respect to those Shares during the Period of Restriction.

8.5.     DIVIDENDS AND OTHER DISTRIBUTIONS.  During the Period of Restriction,
Participants holding Shares of Restricted Stock granted hereunder may be
credited with regular cash dividends paid with respect to the Shares while they
are so held.  The Board may apply any restrictions to the dividends that the
Board deems appropriate.  Without limiting the generality of the preceding
sentence, if the grant or vesting of Restricted Shares granted to a Covered
Employee is designed to comply with the requirements of the Performance-Based
Exception, the Board may apply any restrictions it deems appropriate to the
payment of dividends declared with respect to such Restricted Shares,
including, without limitation, that the dividends and/or the Restricted Shares
maintain eligibility for the Performance-Based Exception.

discretion of the Board, Participants may be entitled to receive any dividends

         Subject to the terms of the Plan, the Board may grant other

                              PERFORMANCE MEASURES

         Unless and until the Board proposes for stockholder vote and
stockholders approve a change in the general performance measures set forth in
this Article 12, the attainment of which may determine the degree of payout
and/or vesting with respect to Awards to Covered Employees




                                     11
<PAGE>   12

which are designed to qualify for the Performance-Based Exception, the
performance measure(s) to be used for purposes of such grants shall be chosen
from among:

         (a)     Earnings per share;

         (b)     Net income (before or after taxes);

         (c)     Return measures (including, but not limited to, return on

which are held by Covered Employee, may not be adjusted upward (the Board shall
retain the discretion to adjust such Awards downward).  In the event that
applicable tax and/or securities laws change to permit Board discretion to
alter the governing performance measures without obtaining stockholder approval
of such changes, the Board shall have sole discretion to make such changes
without obtaining stockholder approval.  In addition, in the event that the
Board determines that it is advisable to grant Awards which shall not qualify
for the Performance-Based Exception, the Board may make such grants without
satisfying the requirements of Code Section 162(m).

                                  ARTICLE 13.
                            BENEFICIARY DESIGNATION

         Each Participant under the Plan may, from time to time, name any
beneficiary or beneficiaries (who may be named contingently or successively) to
whom any benefit under the Plan is to be paid in case of his or her death
before he or she receives any or all of such benefit.  Each such designation
shall revoke all prior designations by the same Participant, shall be in a form
prescribed by the Company, and will be effective only when filed by the
Participant in writing with the Company during the Participant's lifetime.  In
the absence of any such designation, benefits remaining unpaid at the
Participant's death shall be paid to the Participant's estate.

                                   DEFERRALS

         The Board may permit or require a Participant to defer such
Participant's receipt of the payment of cash or the delivery of Shares that
would otherwise be due to such Participant by virtue of the exercise of an
Option or SAR, the lapse or waiver of restrictions with respect to Restricted
Stock, or the satisfaction of any requirements or goals with respect to
Performance Units/Shares.  If any such deferral election is required or
permitted, the Board shall, in its sole discretion, establish rules and
procedures for such payment deferrals.

                                  ARTICLE 15.
                         RIGHTS OF EMPLOYEES/DIRECTORS

15.1.    EMPLOYMENT.  Nothing in the Plan shall interfere with or limit in any
way the right of the Company to terminate any Participant's employment at any
time, nor confer upon any Participant any right to continue in the employ of
the Company.

15.2.    PARTICIPATION.  No Employee or Director shall have the right to be
selected to receive an Award under this Plan, or, having been so selected, to

Participant's Award Agreement shall set forth the extent to which the
Participant shall have the right to exercise and/or receive payment for any
Award following termination of the Participant's employment or directorship
with the Company, or termination of relationship with the Company.  Such
provisions shall be determined in the sole discretion of the Board, shall be
included in the Award Agreement entered into with each Participant, need not be
uniform among Awards and may reflect distinctions based on the reasons for
termination.

15.4     NONTRANSFERABILITY.  Except as otherwise provided in a Participant's
Award Agreement, Awards may not be sold, transferred, pledged, assigned, or
otherwise alienated or hypothecated, other than by will or by the laws of
decent and distribution.   Further, except as otherwise provided in a
Participant's Award Agreement, a Participant's rights under the Plan shall be
exercisable during the Participant's lifetime only by the Participant or the
Participant's legal representative.

                               CHANGE IN CONTROL

Control, unless otherwise specifically prohibited under applicable laws, or by
the rules and regulations of any governing governmental agencies or national
securities exchanges:

         immediately exercisable, and shall remain exercisable throughout their
         entire term;



                                     13

<PAGE>   14


         (b)     Any restriction periods and restrictions imposed on Restricted
         Shares which are not performance-based shall lapse;

         (c)     The target payout opportunities attainable under all
         outstanding Awards of performance-based Restricted Stock, Performance
         Units, Performance Shares, and Cash-Based Awards and Share-Based
         Awards shall be deemed to have been fully earned for the entire
         Performance Period(s) as of the effective date of the Change in
         Control.  The vesting of all Awards denominated in Shares shall be
         accelerated as of the effective date of the Change in Control, and
         there shall be paid out to Participants within thirty (30) days
         following the effective date of the Change in Control a pro rata
         number of shares based upon an assumed achievement of all relevant
         targeted performance goals and upon the length of time within the
         Performance Period which has elapsed prior to the Change in Control.
         Awards denominated in cash shall be paid pro rata to participants in
         cash within thirty (30) days following the effective date of the
         Change in Control, with the proration determined as a function of the
         length of time within the Performance Period which has elapsed prior
         to the Change in Control, and based on an assumed achievement of all
         relevant targeted performance goals.

16.2.    TERMINATION, AMENDMENT, AND MODIFICATIONS OF CHANGE-IN-CONTROL
PROVISIONS.  Notwithstanding any other provision of this Plan (but subject to
the limitations of Section 17.3 hereof) or any Award Agreement provision, the
provisions of this Article 16 may not be terminated, amended, or modified on or
after the date of a Change in Control to affect adversely any Award theretofore
granted under the Plan without the prior written consent of the Participant
with respect to said Participant's outstanding Awards; provided, however, the
Board may terminate, amend, or modify this Article 16 at any time and from time
to time prior to the date of a Change in Control.

16.3.    POOLING OF INTERESTS ACCOUNTING.  Notwithstanding any other provision
of the Plan to the contrary, in the event that the consummation of a Change in
Control is contingent on using pooling of interests accounting methodology, the
Board may take any action necessary to preserve the use of pooling of interests
accounting.

                                  ARTICLE 17.
                    AMENDMENT, MODIFICATION, AND TERMINATION

17.4, the Board may at any time and from time to time, alter, amend, suspend or
terminate the Plan in whole or in part, provided that no amendment shall be
made without stockholder approval if such approval is necessary to comply with
any applicable tax or regulatory requirements.  Prior to such approval, Awards
may be made under the Plan expressly subject to such approval.

17.2.    ADJUSTMENT OF AWARDS UPON THE OCCURRENCE OF CERTAIN UNUSUAL OR
NONRECURRING EVENTS.  The Board may make adjustments in the terms and
conditions of, and the criteria included in, Awards in recognition of unusual
or nonrecurring events (including, without limitation, the events described in
Section 4.2 hereof) affecting the Company or the financial statements of the
Company or of changes in applicable laws, regulations, or



                                     14

<PAGE>   15

accounting principles, whenever the Board determines that such adjustments are
appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Plan; provided that
no such adjustment shall be authorized to the extent that such authority would
be inconsistent with the Plan's meeting the requirements of Section 162(m) of
the Code.

17.3.    AWARDS PREVIOUSLY GRANTED.  Notwithstanding any other provision of the
Plan to the contrary (but subject to Sections 4.2 and 16.3 hereof), no
termination, amendment, or modification of the Plan shall adversely affect in
any material way any Award previously granted under the Plan, without the
written consent of the Participant holding such Award.

17.4.    COMPLIANCE WITH CODE SECTION 162(m).  At all times when Code Section
162(m) is applicable, all Awards granted under this Plan shall comply with the
requirements of Code Section 162(m); provided, however, that in the event the
Board determines that such compliance is not desired with respect to any Award
or Awards available for grant under the Plan, then compliance with Code Section
162(m) will not be required.  In addition, in the event that changes are made
to Code Section 162(m) to permit greater flexibility with respect to any Award
or Awards available under the Plan, the Board may, subject to this Article 17,
make any adjustments it deems appropriate.

                                  ARTICLE 18.

deduct or withhold, or require a Participant to remit to the Company, an amount
sufficient to satisfy Federal, state, and local taxes, domestic or foreign,
required by law or regulation to be withheld with respect to any taxable event
arising as a result of this Plan.

18.2.    SHARE WITHHOLDING.  With respect to withholding required upon the
exercise of Options or SARs, upon the lapse of restrictions on Restricted
Stock, or upon any other taxable event arising as a result of Awards granted
hereunder, Participants may elect, subject to the approval of the Board, to
satisfy the withholding requirement, in whole or in part, by having the Company
withhold Shares having a Fair Market Value on the date the tax is to be
determined equal to the minimum statutory total tax which could be imposed on
the transaction.  All such elections shall be irrevocable, made in writing,
signed by the Participant, and shall be subject to any restrictions or
limitations that the Board, in its sole discretion, deems appropriate.

                                  ARTICLE 19.
                                INDEMNIFICATION

         Each person who is or shall have been a member of the Committee, or of
the Board, shall be indemnified and held harmless by the Company against and
from any loss, cost, liability, or expense that may be imposed upon or

The foregoing right of indemnification shall not be exclusive of any other
rights of indemnification to which such persons may be entitled under the
Company's Articles of Incorporation of Bylaws, as a matter of law, or
otherwise, or any power that the Company may have to indemnify them or hold
them harmless.

                                  ARTICLE 20.
                                   SUCCESSORS

         All obligations of the Company under the Plan with respect to Awards

business and/or assets of the Company.

[NORWEST BANK MINNESOTA,
NATIONAL ASSOCIATION LOGO]                                   CREDIT AGREEMENT

THIS CREDIT AGREEMENT (the "Agreement") is executed this 1st day of June, 1998
to be effective as of the date described in the first paragraph of the
Background section set forth immediately below (the "Effective Date"), and is
between Norwest Bank Minnesota, National Association (the "Bank") and Datalink
Corporation (the "Borrower").

BACKGROUND

The Borrower has asked the Bank to renew its existing line of credit (the
"Line") in the amount of Ten Million and 00/100 Dollars ($10,000,000.00), to be
effective as of the date that the treasurer of the Borrower has received at
least a net $23,000,000.00 in available funds from the initial public offering
of its common stock offered through certain underwriters led by Needham &
Company, Inc., Cruttenden Roth Incorporated, and John G. Kinnard and Company,
Incorporated.  (The date that net funds in this amount have been received to be
referred to as the "Effective Date".)

The obligations of the Borrower to the Bank with respect to the Line prior to
the Effective Date of this Agreement were evidenced by a Credit Agreement dated
June 1, 1998 (the "June 1998 Credit Agreement"), which June 1998 Credit
Agreement is to be replaced by this Agreement and will have no further effect. 
Borrowings under the Line are currently evidenced by a promissory note dated
June 1, 1998 (the "June 1998 Revolving Note").

The Bank is agreeable to meeting the Borrower's request provided that the
Borrower agrees to the terms and conditions of this Agreement.

The Revolving Note, this Agreement, and all "Security Documents" described in
Exhibit B shall be referred to collectively as the "Documents."

In consideration of the above premises, the Bank and the Borrower agree as
follows:

1.      LINE OF CREDIT

1.1     LINE OF CREDIT AMOUNT.  During the Line Availability Period defined
        below, the Bank agrees to provide a revolving line of credit
        (the "Line") to the Borrower.  Outstanding amounts under the Line shall
        not, at any one time, exceed the lesser of the Borrowing Base or Ten
        Million and 00/100 Dollars ($10,000,000.00). The Borrowing Base is
        defined in Exhibit A-1 to this Agreement.

1.2     LINE AVAILABILITY PERIOD.  The "Line Availability Period" shall mean
        the period of time from the Effective Date or the date on which
        all conditions precedent described in this Agreement have been met,
        whichever is later, to the Line Expiration Date of May 31, 2000.

1.3     THE REVOLVING NOTE.  The Borrower's obligation to repay advances under
        the Line shall be evidenced by a single promissory note (the
        "Revolving Note") dated as of the Effective Date, and in form and
        content acceptable to the Bank.  The Revolving Note shall replace, but
        not be deemed to satisfy, the June 1998 Revolving Note.  Reference is
        made to the Revolving Note for interest rate and repayment terms.

1.4     MANDATORY PREPAYMENT.  If at any time the principal outstanding under 
        the Revolving Note plus the face amount of any outstanding Standby
        L/Cs and Documentary L/Cs (as defined below) exceed the lesser of the
        Borrowing Base or $10,000,000.00, the Borrower must immediately prepay
        the Revolving Note in an amount sufficient to eliminate the excess.  If
        after making this prepayment the face amount of outstanding Standby
        L/Cs and Documentary L/Cs continue to exceed this amount, then the
        Borrower shall deposit sufficient cash into a non-interest bearing
        account to collateralize the excess.  The Borrower hereby grants the
        Bank a security interest in these funds as security for all of the
        Borrower's obligations to the Bank.

1.5     STANDBY LETTERS OF CREDIT

(a)     Issuance and Expiration. During the Line Availability Period, the Bank
        may in its sole discretion issue standby letters of credit for the
        account of the Borrower ("Standby L/Cs"), provided that the Borrower is
        in compliance with the terms of this Agreement. Each Standby L/C must
        expire no later than the Line Expiration Date. Prior to the issuance
        of a Standby L/C, the Borrower will execute the Bank's standard
        Application and Agreement for Irrevocable Standby Letter of Credit
        ("Standby L/C Agreement") and such other documents as the Bank deems
        necessary.
        
(b)     Fees. The Borrower will pay a standby letter of credit fee of 1.00% per
        annum on the face amount of each Standby L/C subject to a minimum fee of
        $200. This fee will be paid annually in advance and is in addition to
        all other fees or expenses provided for in the Standby L/C Agreement.

(c)     Reduction of Line Availability and Line Advances. The availability under
        the Line will be reduced dollar for dollar by the face amount of all
        outstanding Standby L/Cs plus any unreimbursed draws. Without limiting
        any rights and remedies available to the Bank under any Standby L/C
        Agreement, any draw under a Standby L/C may, at the Bank's option, be
        repaid through an automatic advance under the Line and the advance will
        be repayable per the terms of this Agreement.

(d)     Cash Collateralization of Outstanding Standby L/Cs. Should a default
        occur under this Agreement, the Bank may require the Borrower to
        deposit with it in a non-interest bearing account, immediately
        available funds equal to the face amount of outstanding Standby L/Cs.
        The Borrower hereby grants the Bank a security interest in the funds
        which will be security for all of the Borrower's obligations to the
        Bank.

1.6     DOCUMENTARY LETTERS OF CREDIT

(a)     Issuance and Expiration. During the Line Availability Period, the Bank
        agrees to issue documentary letters of credit for the account of the
        Borrower ("Documentary L/Cs"), provided that the Borrower is in
        compliance with the terms of this Agreement. Each Documentary L/C must
        expire prior to the Line Expiration Date. Prior to the issuance of a
        Documentary L/C, the Borrower will execute the Bank's standard Master
        Security Agreement for Irrevocable Documentary Letters of Credit (the
        "Documentary L/C Agreement") and such other documents as the Bank deems
        necessary.
        
(b)     Fees and Expenses. Fees and expenses related to each Documentary L/C
        will be agreed upon at issuance.

                                     -2-

<PAGE>   3


(c)     Reduction of Line Availability and Line Advances. The availability under
        the Line will be reduced dollar for dollar by the face amount of all
        outstanding Documentary L/Cs, plus any unreimbursed draws. Without
        limiting any rights and remedies available to the Bank under the
        Documentary L/C Agreement and related documents, any draw under a
        Documentary L/C may, at the Bank's option, be repaid through an
        automatic advance under the Line and the advance will be repayable
        according to the terms of this Agreement.

(d)     Cash Collateralization of Outstanding Documentary L/Cs. Should a default
        occur under this Agreement, the Bank may require the Borrower to
        deposit with it in a non-interest bearing account, immediately available
        funds equal to the face amount of the outstanding Documentary L/Cs. The
        Borrower hereby grants the Bank a security interest in the funds which
        will be security for all of the Borrower's obligations to the Bank.

2.      FEES AND EXPENSES

2.1     COMMITMENT FEE. During the Line Availability Period the Borrower shall
        pay the Bank a commitment fee of 0.125% per annum on the average daily 
        unused amount of the Line. This fee shall be calculated on the basis of
        actual days elapsed in a 360 day year and paid quarterly in arrears 
        beginning the first fiscal quarter end after the Effective Date.

2.2     COLLECTION EXPENSES.  In the event the Borrower fails to pay the Bank
        any amounts due under this Agreement or under the Documents, the
        Borrower will pay all costs of collection, including reasonable
        attorneys' fees and legal expenses incurred by the Bank.

2.3     AUDIT EXPENSE.  The Borrower agrees to reimburse the Bank for the cost
        of periodic audits of all collateral pledged to the Bank which may be   
        conducted no more frequently than twice each calendar year and at a
        cost of no more than $2,000.00 per audit.  The audits may be performed
        by employees of the Bank or independent contractors retained by the
        Bank.

3.      ADVANCES AND PAYMENTS

3.1     REQUESTS FOR ADVANCES.  Any Line advance permitted under this Agreement
        must be requested by telephone or in a writing delivered to the Bank
        (or transmitted via facsimile) by any person reasonably believed by the
        Bank to be an authorized officer of the Borrower.  The Bank will
        not consider any such request if there is an event which is, or with
        notice or the lapse of time would be, an event of default under this
        Agreement.  Proceeds will be deposited into the Borrower's account at
        the Bank or disbursed in such other manner as the parties agree.

3.2     INTEREST RATE OPTIONS.  In addition to interest rates based on the Base
        Rate Option defined in the Revolving Note, the Borrower may elect a
        fixed rate of interest for a fixed time period and principal amount
        agreeable to the Bank and Borrower that is based upon any applicable
        margin stated in said promissory note and an interest rate derived from
        the current LIBOR rate available to the Bank on national or
        international money markets for a similar time period and dollar
        amount.


                                     -3-
<PAGE>   4

        To elect the LIBOR Rate Option, as defined in the Revolving Note, the
        Borrower must request a quote from the Bank two days prior to funding. 
        This request must designate an amount (the "LIBOR Rate Portion") and a
        period (the "LIBOR Interest Period").  The LIBOR Rate Portion must be
        at least $100,000 and the LIBOR Interest Period will be for 30, 60 or
        90 days or such other period to which the parties may agree.  The Bank
        shall not be obligated to provide a LIBOR rate quote if it determines
        that no deposits with an amount and maturity equal to those for which a
        quotation has been requested are available to it in the London
        interbank market.  The Borrower must orally accept a quote when
        received or it will be deemed rejected.  If accepted, the LIBOR Rate
        Option will remain in effect for the LIBOR Interest Period specified in
        the quote.  At the end of each LIBOR Interest Period the principal
        amount subject to the LIBOR Rate Option shall bear interest at the
        Base Rate Option (as defined in the Revolving Note).

3.3     PAYMENTS.  All principal, interest and fees due under the Documents
        will be paid to the Bank by the direct debit of available funds on
        deposit in the Borrower's account with the Bank.  The Bank will debit
        the account on the dates the payments become due.  If a due date
        does not fall on a day on which the Bank is open for substantially all
        of its business (a "Banking Day", except as otherwise provided), the
        Bank will debit the account on the next Banking Day, and interest will
        continue to accrue during the extended period.  If there are
        insufficient funds in the account on the day the Bank enters any debit
        authorized by this Agreement, the debit will be reversed and the
        payment will be due immediately without necessity of demand by direct
        remittance of immediately available funds.  For amounts bearing
        interest at the LIBOR Rate (if any) a Banking Day is a day on which the
        Bank is open for business and on which dealings in U.S. dollar deposits
        are carried on in the London interbank market.

4.      SECURITY

        During the time period that credit is available under this Agreement,
        and afterward until all amounts due under the Documents are paid in
        full, unless the Bank shall otherwise agree in writing, all amounts
        due under this Agreement and the Documents shall be secured at all
        times as provided in Exhibit B.  The Borrower also hereby grants the
        Bank a security interest (independent of the Bank's right of set-off)
        in its deposit accounts at the Bank and in any other debt obligations
        of the Bank to the Borrower.

        These covenants were negotiated by the Bank and Borrower based on

        the Borrower will be made in the sole discretion of the Bank. These
        options do not limit the Bank's right to exercise its rights under
        Section 8 of this Agreement.

        receiver is appointed for any of the Borrower's properties, or if a

        Bankruptcy Code, then the Line shall immediately terminate and the
        unpaid  principal, accrued interest and all other amounts payable under
        the Revolving Note and the Documents will become immediately due
        and payable without notice or demand.

$10,000,000.00                                          June 1, 1998


FOR VALUE RECEIVED, Datalink Corporation (the "Borrower") promises to pay to the
order of Norwest Bank Minnesota, National Association (the "Bank"), at its
principal office or such other address as the Bank or holder may designate from
time to time, the principal sum of Ten Million and 00/100 Dollars
($10,000,000.00), or the amount shown on the Bank's records to be outstanding,
plus interest (calculated on the basis of actual days elapsed in a 360-day
year) accruing on the unpaid balance at the annual interest rate defined
below.  Absent manifest error the Bank's records will be conclusive evidence of
the principal and accrued interest owing hereunder.

This Revolving Note is issued pursuant to a Credit Agreement of even date
herewith between the Bank and the Borrower (the "Agreement") and replaces but
shall not be deemed to satisfy the June 1998 Revolving Note as defined in the
Agreement.  The Agreement, and any amendments or substitutions thereto, contain
additional terms and conditions including default and acceleration provisions.
The terms of the Agreement are incorporated into this Revolving Note by
reference.  Capitalized terms not expressly defined herein shall have the
meanings given them in the Agreement.

INTEREST RATE.

BASE RATE OPTION.  Unless the Borrower chooses the LIBOR Interest Rate Option
as defined below, the principal balance outstanding under this Revolving Note
shall bear interest at an annual rate equal to the Base Rate, floating (the 
"Base Rate Option").  Base Rate means the rate of interest established by the 
Bank from time to time as its "base" or "prime" rate of interest at its 
principal office in Minneapolis, Minnesota.

LIBOR INTEREST RATE OPTION.  Subject to the terms and conditions of the
Agreement the Borrower may elect that all or portions of the principal balance
of this Revolving Note bear interest at the LIBOR Interest Rate plus 1.95% (the
"LIBOR Interest Rate Option").  Specific reference is made to the Interest Rate
Options section of the Agreement for terms governing the designation of interest
periods and rate portions.

The LIBOR Interest Rate shall be computed in accordance with the following 
formula.

         LIBOR Interest Rate = London Interbank Offered Rate
                               -----------------------------
                               1.00 - Reserve Requirement

         Where,

         (1) "London Interbank Offered Rate" means the Bank's cost of funds as
         determined by the Bank's Treasury Division, based upon the average rate
         at which U.S. Dollar deposits with a term equal to the applicable LIBOR
         Interest Rate Period and in an amount equal to the LIBOR Interest Rate
         Portion are available to the Bank at the time or determination on the
         London Interbank Market.

         (2) "Reserve Requirement" means the Federal Reserve System requirement
         (expressed as a percentage) applicable to the dollar deposits used in
         calculating the LIBOR Interest Rate above.

     WHEREAS, the Bylaws of the Company require the Company to indemnify its
directors to the full extent permitted by law and Indemnitee is serving as a
director of the Company, in part, in reliance on such Bylaws; and

     WHEREAS, in recognition of Indemnitee's need for substantial protection
against personal liability in order to maintain Indemnitee's continued service
to the Company in an effective manner and Indemnitee's reliance on the aforesaid
Bylaws and, in part, to provide Indemnitee with specific contractual assurance
that the protection promised by such Bylaws will be available to Indemnitee
(regardless of, among other things, any amendment to or revocation of such
Bylaws or any change in the composition of the Company's Board of Directors or
any acquisition transaction relating to the Company), the Company desires to
provide in this Agreement for the indemnification of and the advance of expenses

as set forth in this Agreement and, to the extent officers' and directors'
liability insurance is maintained by the Company, to provide for the continued
coverage of Indemnitee under the Company's officers' and directors' liability
insurance policies;

     NOW, THEREFORE, in consideration of the covenants contained herein and of
Indemnitee's continuing service to the Company directly or, at its request,
other enterprises, and intending to be legally bound hereby, the parties hereto
agree as follows:

     1.   CERTAIN DEFINITIONS.
     

          (a) CHANGE IN CONTROL.  A Change in Control shall be deemed to have
     occurred if (i) any "person" (as such term is used in Section 13(d) and
     14(d) of the Securities Exchange Act of 1934, as amended), other than a
     trustee or other fiduciary holding securities under an employee benefit
     plan of the Company or a corporation owned directly or indirectly by the
     stockholders of the Company in substantially the same proportions as their
     ownership of stock of the Company, is or becomes the "beneficial owner" (as
     defined in Rule 13d-3 under said Act), directly or indirectly, of
     securities of the Company representing 20% or more of the total voting
     power represented by the Company's then outstanding Voting Securities, or
     (ii) during any period of two consecutive years, individuals who at the
     beginning of such period constituted the Board of Directors of the 


<PAGE>   2

     Company, and any new director whose election by the Board of Directors or
     nomination for election by the Company's stockholders was approved by a
     vote of at least two-thirds (2/3) of the directors then still in office who
     either were (x) directors at the beginning of the period or (y) whose
     election or nomination for election by the Company's stockholders was
     approved by a vote of at least two-thirds (2/3) of the directors then still
     in office who either were directors at the beginning of the period or whose
     election or nomination for election was previously so approved, cease for
     any reason to constitute a majority of the Board of Directors, or (iii) the
     stockholders of the Company approve a merger or consolidation of the
     Company with any other corporation, other than a merger or consolidation
     which would result in the Voting Securities of the Company outstanding
     immediately prior to such a merger or consolidation continuing to represent
     (either by remaining outstanding or by being converted into Voting
     Securities of the surviving entity) at least 80% of the total voting power
     represented by the Voting Securities of the Company or such surviving
     entity outstanding immediately after such merger or consolidation, or the
     stockholders of the Company approve a plan of complete liquidation of the
     Company or an agreement for the sale or disposition by the Company (in one
     transaction or a series of transactions) of all or substantially all of the
     Company's assets.  A "Change of Control" shall not be deemed to occur as a
     result of transactions in contemplation of or in connection with the
     Company's initial public offering of Common Stock, including without
     limitation, the election of Class I, Class II and Class III directors or
     the issuance of Common Stock to the public in the offering.

          (b)  CLAIM.  Any threatened, pending, or completed action, suit,
     arbitration, alternate dispute resolution mechanism, investigation, or
     proceeding, and any appeal thereof, whether civil, criminal, 
     administrative, or investigative and/or any inquiry or investigation,
     whether conducted by the Company or any other party that Indemnitee in good
     faith believes might lead to the institution of any such action.

          (c) EXPENSES.  Include attorneys' fees and all other costs, expenses,
     and obligations, including retainers, court costs, transcript costs, expert
     fees, witness fees, travel expenses, duplicating costs, printing and
     binding costs, telephone charges, postage, and delivery services fees, paid
     or incurred in connection with investigating, defending, being a witness in
     or participating in (including on appeal), or preparing to defend, be a
     witness in or participate in any claim relating to any Indemnifiable Event.

          (d) INDEMNIFIABLE  EVENT.  Any event, occurrence, or circumstance
     related to the fact that Indemnitee is or was a director, officer,
     employee, trustee, agent, or fiduciary of the Company, or is or was serving
     at the request of the Company as a director, officer, employee, trustee,
     agent or fiduciary of any other corporation, partnership, joint venture,
     employee benefit plan, trust or other enterprise, or by reason of anything
     done or not done by Indemnitee in any such capacity.

          (e) POTENTIAL CHANGE IN CONTROL.  Shall be deemed to have occurred if
     (i) the Company enters into an agreement or arrangement, the consummation
     of which would 

                                      -2-


<PAGE>   3

     result in the occurrence of a Change in Control; (ii) any person
     (including the Company) publicly announces an intention to take or
     to consider taking actions which if consummated would constitute a Change
     in Control; (iii) any person (other than a trustee or other fiduciary
     holding securities under an employee benefit plan of the Company acting in
     such capacity or a corporation owned, directly or indirectly, by the
     stockholders of the Company in substantially the same proportions as their
     ownership of stock of the Company), who is or becomes the beneficial
     owner, directly or indirectly, of securities of the Company representing
     10% or more of the combined voting power of the Company's then outstanding
     Voting Securities increases his beneficial ownership of such securities by
     5% or more over the  percentage so owned by such person on the date
     hereof; or (iv) the Board  adopts a resolution to the effect that, for
     purposes of this Agreement,  a Potential Change in Control has occurred. A
     "Potential Change of Control"  shall not be deemed to occur as a result of
     transactions in contemplation of  or in connection with the Company's
     initial public offering of Common Stock, including without limitation, the
     election of Class I, Class II and Class III directors or the issuance of
     Common Stock to the public in the offering.

          (f) REVIEWING PARTY. Any appropriate person or body consisting of a
     member or members of the Company's Board of Directors including the Special
     Independent Counsel referred to in Section 4 (or, to the fullest extent
     permitted by law, any other person or body appointed by the Board), who is
     not a party to the particular claim for which Indemnitee is seeking
     indemnification.

          (g) VOTING SECURITIES. Any securities of the Company which vote
     generally in the election of directors.

     2.   AGREEMENT TO SERVE. Indemnitee agrees to continue to serve as a 
director of the Company.  Indemnitee may at any time and for any reason resign
from such position (subject to any other contractual obligation or any
obligation imposed by operation of law). The Company shall have no obligation 
under this Agreement to continue Indemnitee in any position with the Company.
      
     3.   BASIC INDEMNIFICATION AGREEMENT.

          (a) In the event Indemnitee was, is or becomes a party to or witness
     or other participant in, or is threatened to be made a party to or
     witness or other participant in, a Claim by reason of (or airing in party
     out of), an Indemnifiable Event, the Company shall indemnify Indemnitee to
     the fullest extent permitted by law, as soon as practicable but in any
     event no later than thirty days after written demand is presented to the
     Company against any and all expenses, judgments, fines, penalties, and
     amounts paid in settlement (including all interest, assessments, and other
     charges paid or payable in connection with or in respect of such expenses,
     judgments, fines,  penalties,  or amounts paid in  settlement) of such
     Claim. Notwithstanding anything in this Agreement to the contrary, prior
     to a Change in Control, Indemnitee shall not be entitled to 
     indemnification pursuant to this Agreement in connection with any Claim
     initiated by Indemnitee against the Company or any director 

                                     -3-

<PAGE>   4


     or officer of the Company  unless the Company has joined in or consented
     to the initiation of such Claim.  If so requested by  Indemnitee,  the
     Company shall  advance  (within  two  business  days of such  request) 
     any and all Expenses to Indemnitee (an "Expense Advance").
        
          (b) Notwithstanding the foregoing, (i) the obligations of the Company
     under Section 3(a) shall be subject to the condition that any  Reviewing
     Party shall not have determined in a written opinion (in any case in which
     the Special Independent Counsel referred to in Section 4 hereof is
     involved) that Indemnitee would not be permitted to be indemnified under
     applicable law, and (ii) the obligation of the Company to make an Expense
     Advance pursuant to Section 3(a) shall be subject to the condition that
     if, when and to the extent that any Reviewing Party determines that
     Indemnitee would not be permitted  to be so indemnified under applicable
     law, the Company shall be entitled to be reimbursed by Indemnitee (who
     hereby agrees to reimburse the  Company, without interest) for all such
     amounts theretofore paid; provided, however, that if Indemnitee has
     commenced legal proceedings in a court of competent jurisdiction to secure
     a determination that Indemnitee  should be indemnified under applicable
     law, any determination made by a Reviewing Party that Indemnitee would not
     be permitted to be indemnified under applicable law shall not be binding
     and Indemnitee shall not be required to reimburse the Company for any
     Expense Advance until a final judicial determination is made with respect
     thereto (as to which all rights of appeal therefrom have been exhausted or
     lapsed). If there has not been a Change in Control, a  Reviewing Party
     shall be selected by the Board of Directors, and if there has been such a
     Change in Control, a Reviewing Party shall be the Special Independent
     Counsel referred to in Section 4 hereof. If there has been no appointment
     or no determination by a Reviewing Party or if a Reviewing Party
     determines that Indemnitee substantively would not be permitted to be
     indemnified in whole or in part under applicable  law, Indemnitee shall
     have the right to commence litigation in any court in the State of
     Minnesota having subject matter jurisdiction thereof and in which venue is
     proper seeking an initial determination by the court or challenging any
     such determination by the court or challenging any such determination by
     the Reviewing Party or any aspect  thereof, including the legal or factual
     basis therefor, and the Company hereby (i) consents to service of process
     and to appear in any such proceeding, (ii) shall be precluded from
     asserting that the procedures and presumptions of this Agreement are not
     valid, binding, and enforceable, and (iii) shall stipulate in any
     such proceeding that the Company is bound by all the provisions of this
     Agreement. Any  determination by the Reviewing Party otherwise shall be
     conclusive  and binding on the Company and Indemnitee.

     4.  CHANGE IN  CONTROL.  The  Company  agrees  that if there is a Change in
Control of the Company  (other than a Change in Control  which has been
approved by a majority of the Company's Board of Directors who were
directors immediately prior to such Change in  Control)  then with  respect to
all matters  thereafter arising  concerning  the rights of Indemnitee  to
indemnity  payment and Expense Advances under this Agreement or any other
agreement, the Company's Articles of Incorporation,  or the Company's  Bylaws
now or hereafter in effect  relating to Claims for Indemnifiable  Events,  the
Company shall seek legal advice only from "Special Independent 

                                      -4-

<PAGE>   5


Counsel" selected by Indemnitee and approved by the Company (which 
approval shall not be unreasonably withheld), and who has not otherwise 
performed services for the Company or Indemnitee within the last five years
(other than in connection with such matters). Such Special Independent 
Counsel, among other things, shall render its written opinion to the Company
and Indemnitee as to whether and to what extent the Indemnitee would be
permitted to be indemnified under applicable law. The Company agrees to pay
the reasonable fees of the Special Independent Counsel referred to above
and may fully indemnify such Special Independent Counsel against any and all
expenses (including attorney's fees), claims, liabilities, and damages 
arising out of or relating to this Agreement or its engagement pursuant
hereto.

    5. ESTABLISHMENT OF TRUST. In the event of Potential Change in Control, the
Company shall, upon written request by Indemnitee, create a "Trust" for
the benefit of Indemnitee and from time to time upon written request of
Indemnitee shall fund such Trust in an amount sufficient to satisfy any
and all Expenses reasonably anticipated at the time of each such request 
to be incurred in connection with investigating, preparing for and defending
any Claim relating to an Indemnifiable Event, and any and all judgments, 
fines, penalties, and settlement amounts of any and all Claims relating to an
Indemnifiable Event from time to time actually paid or claimed, reasonably
anticipated or proposed to be paid. The amount or amounts to be deposited 
in the Trust pursuant to the foregoing funding obligation shall be
determined by a Reviewing Party, in any case in which the Special Independent
Counsel referred to above is involved. The Terms of the Trust shall provide 
that upon a Change in Control (i) the Trust shall not be revoked or the 
principal thereof invaded, without the written consent of the Indemnitee, 
(ii) the Trustee shall advance, within two business days of a request by the
Indemnitee, any and all Expenses to the Indemnitee (and the Indemnitee hereby 
agrees to reimburse the Trust under the circumstances under which the 
Indemnitee would be required to reimburse the Company under Section 3(b) of
this Agreement, (iii) the Trust shall continue to be funded by the Company in
accordance with the funding obligation set forth above, (iv) the Trustee 
shall promptly pay to the Indemnitee all amounts for which the
Indemnitee shall be entitled to indemnification pursuant to this Agreement
or otherwise, and (v) all unexpended funds in such Trust shall revert to
the Company upon a final determination by the Reviewing Party or a 
court of competent jurisdiction, as the case may be, that the Indemnitee has
been fully indemnified under the terms of this Agreement. The Trustee shall
be a bank or trust company or other individual or entity chosen by the 
Indemnitee and acceptable and approved by the Company. Nothing in this
Section 5 shall relieve the Company of any of its obligations under this
Agreement.

    6. INDEMNIFICATION FOR ADDITIONAL EXPENSES. To the fullest extent permitted
by law, the Company shall indemnify against any and all Expenses 
(including attorney's fees) and, if requested by Indemnitee, shall (within
two business days of such request) advance such Expenses to Indemnitee,
which are incurred by Indemnitee in connection with any Claim asserted 
against or action brought by Indemnitee for (i) indemnification or advance
payment of Expenses by the Company under this Agreement or any other agreement, 
the Company's Bylaws, or Articles of Incorporation hereafter in effect
relating to Claims for Indemnifiable Events and/or (ii) recovery under any 
directors' and officers' liability insurance policies maintained by the
Company,  

                                      -5-


<PAGE>   6

regardless of whether Indemnitee ultimately is determined to be entitled to such
indemnification, Expense advance or insurance recovery, as the case may be.

     7.  PARTIAL INDEMNITY, ETC. If Indemnitee is entitled under any provision
of this Agreement to indemnification by the Company for some or a portion of
the expenses, judgments, fines, penalties, and amounts paid in settlement of a
claim but not, however, for all of the total amount thereof, the Company 
shall nevertheless indemnify Indemnitee for the portion thereof to which
Indemnitee is entitled. Moreover, notwithstanding any other provision of this
Agreement, all Claims relating in whole or in part to any Indemnifiable Event
or in defense of any issue or matter therein, including dismissal without
prejudice, Indemnitee shall be indemnified against all Expenses incurred in
connection therewith. In connection with any determination by the 
Reviewing Party or otherwise as to whether Indemnitee is entitled to be
indemnified hereunder the burden of proof shall be on the Company to establish
that Indemnitee is not so entitled.
        
     8.  CONTRIBUTION.  If the indemnification provided in this Agreement is
unavailable and may not be paid to Indemnitee because such indemnification is
not permitted by law, then in respect of any threatened, pending, or completed
Claim in which the Company is jointly liable with Indemnitee (or would be if
joined in such Claim), the Company shall contribute, to the full extent
permitted by law, to the amount of expenses, judgments, fines, penalties, and
amounts paid in settlement (including all interest, assessments, and other
charges paid or payable in connection with or in respect of such expenses,
judgments, fines, penalties, or amounts paid in settlement) actually incurred
and paid or payable by Indemnitee in such proportion as is appropriate to
reflect (i) the relative benefits received by the Company on the one hand and
Indemnitee on the other hand from the transaction from which such Claim arose,
and (ii) the relative fault of the Company on the one hand and Indemnitee on the
other in connection with the events which resulted in such expenses, judgments,
fines, penalties, and amounts paid in settlement, as well as any other relevant
equitable considerations. The relative fault of the Company on the one hand and
of Indemnitee on the other shall be determined by reference to, among other
things, the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent the circumstances resulting in such expenses,
judgment, fines, penalties, and amounts paid in settlement. The Company agrees
that it would not be just and equitable if contribution pursuant to this
paragraph were determined by pro rata allocation or any other method of
allocation  which  does not take  account  of the  foregoing  equitable
considerations.

     9.  NO PRESUMPTION.  For purposes of this Agreement, to the fullest 
extent permitted by law, the termination of any Claim, action, suit, or
proceeding, by judgment, order, settlement (whether with or without 
court approval) or conviction, or upon a plea of nolo contendere, or its 
equivalent, shall not create a presumption that Indemnitee did not meet any 
particular standard of conduct or have any particular belief or that a
court has determined that indemnification is not permitted by applicable
law.
        
     10. NON-EXCLUSIVITY,  ETC. The rights of the Indemnitee hereunder shall be
in addition to any other rights Indemnitee may have under the Company's Articles
of Incorporation or Bylaws or the Minnesota Business Corporation Act or
otherwise. To the extent that a change in the 

                                       -6-

<PAGE>   7

Minnesota Business Corporation Act (whether by statute or judicial decision)
permits greater indemnification by agreement than would be afforded currently
under the Company's Articles of Incorporation or Bylaws or this Agreement, to
the fullest extent permitted by law it is the intent of the parties hereto that
Indemnitee shall enjoy by this Agreement the greater benefits so afforded by
such change immediately upon the occurrence of such change without further
action by the Company or Indemnitee.

   11. LIABILITY INSURANCE. To the extent the Company maintains an insurance
policy or policies providing directors' and officers' liability insurance,
Indemnitee shall be covered by such policy or policies, in accordance with its
or their terms, to the maximum extent of the coverage available for any director
or officer of the Company. The Board of Directors of the Company shall determine
the amount and coverage of such directors' and officers' liability insurance
from time to time.

   12. PERIOD OF LIMITATIONS. No legal action shall be brought and no cause of
action shall be asserted by or in the right of the Company or any affiliate of
the Company against Indemnitee, Indemnitee's spouse, heirs, executors or
personal or legal representatives after the expiration of two years from the
date of accrual of such cause of action, and any claim or cause of action of the
Company or its affiliate shall be extinguished and deemed released unless
asserted by the timely filing of a legal action within such two-year period;
provided, however, that if any shorter period of limitations is otherwise
applicable to any such cause of action such shorter period shall govern.

   13. AMENDMENTS, ETC.. No supplement, modification, or amendment of this
Agreement shall be binding unless executed in writing by both of the parties
hereto. No waiver of any of the provisions of this Agreement shall be deemed or
shall constitute a waiver of any other provisions hereof (whether or not
similar) nor shall such waiver constitute a continuing waiver.

   14. SUBROGATION. In the event of payment under this Agreement, the Company
shall be subrogated to the extent of such payment to all of the rights of
recovery of Indemnitee, who shall execute all papers required and shall do
everything that may be necessary to secure such rights, including the execution
of such documents necessary to enable the Company effectively to bring suit to
enforce such rights.

   15. NO DUPLICATION OF PAYMENTS. The Company shall not be liable under this
Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, Bylaws, or otherwise) of the amounts otherwise
indemnifiable hereunder.

   16. BINDING EFFECT, ETC.. This Agreement shall be binding upon and inure to
the benefit of and be enforceable by the parties hereto and their respective
successors, assigns, including any direct or indirect successors by purchase,
merger, consolidation, or otherwise to all or substantially all of the business
and/or assets of the Company,  spouses,  heirs, and personal and legal
representatives. The Company shall require and cause any successor (whether
direct or 

                                     -7-

<PAGE>   8

indirect by purchase, merger, consolidation, or otherwise) to all, substantially
all or a substantial part, of the business and/or assets of the Company, by
written agreement in form and substance satisfactory to the Indemnitee,
expressly to assume and agree to perform this Agreement in the same manner and
to the same extent that the Company would be required to perform if no such
succession had taken place. This Agreement shall continue in effect regardless
of whether Indemnitee continues to serve as an officer or director of the
Company or of any other enterprise at the Company's requests.

   17. SEVERABILITY. The provisions of this Agreement shall be severable in
the event that any of the provisions hereof (including any provision within a
single section, paragraph, or sentence) are held by a court of competent
jurisdiction to be invalid, void, or otherwise unenforceable in any respect, and
the validity and enforceability of any such provision in every other respect and
of the remaining provisions hereof shall not be in any way impaired, and shall
remain enforceable to the fullest extent permitted by law.

   18. TERM. All obligations of the Company contained herein shall 
continue during the period Indemnitee serves the Company in a capacity referred
to in Section 2 hereof, and shall continue thereafter so long as Indemnitee
shall be subject to any possible Claim relating to an Indemnifiable Event.

   19. GOVERNING LAW. This Agreement shall be governed by and construed and
enforced in accordance with the laws of the State of Minnesota applicable to
contracts made and to be performed in such State without giving effects to the
principles of conflicts of law.
