SECTION 3.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         Except as set forth on the Schedule of Exceptions attached hereto as
Exhibit F, the Company hereby represents and warrants to each Purchaser as
follows:

         3.1. ORGANIZATION, GOOD STANDING AND QUALIFICATION. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware. The Company has all requisite corporate power and
authority to own and operate its properties and assets, to execute and deliver
this Agreement, the Investor Rights Agreement in the form attached hereto as
Exhibit G (the "Investor Rights Agreement"), and the Shareholders Agreement
attached hereto as Exhibit H (the "Shareholders Agreement") (collectively, the
"Related Agreements"), to issue and sell the Shares and the Conversion Shares
and to carry out the provisions of this Agreement, the Related Agreements and
the Restated Certificate and to carry on its business as presently conducted and
as presently proposed to be conducted. The Company is duly qualified and is
authorized to do business and is in good standing as a foreign corporation in
Colorado and all other jurisdictions in which the nature of its activities and
of its properties (both owned and leased) makes such qualification necessary,
except for those jurisdictions in which failure to do so would not have a
material adverse effect on the Company or its business. The Company owns no
equity securities of any other corporation, limited partnership or similar
entity. The Company is not a participant in any joint venture, partnership or
similar arrangement.

         3.2. CAPITALIZATION; VOTING RIGHTS. The authorized capital stock of the
Company, immediately prior to the Closing, will consist of 10,000,000 shares of
Common Stock, 1,798,347 shares of which are issued and outstanding and 640,000
shares of which are reserved for future issuance to key employees and
consultants pursuant to the Company's 1995 Stock Option Plan, of which 340,000
remain available for issuance under such plan, and 2,746,259 shares of Preferred
Stock, 337,420 of which are designated Series A Preferred Stock, none of which
are issued and outstanding, and 2,408,839 of which are designated Series B
Preferred Stock, none of which are issued and outstanding. All issued and
outstanding shares of the Company's Common Stock (i) have been duly authorized
and validly issued to

                                       3.
<PAGE>   8
the persons listed on Exhibit I hereto, (ii) are fully paid and nonassessable,
and (iii) were issued in compliance with all applicable state and federal laws
concerning the issuance of securities. The rights, preferences, privileges and
restrictions of the Shares are as stated in the Restated Certificate. The
Conversion Shares have been duly and validly reserved for issuance. Other than
as set forth on Exhibit I, and except as may be granted pursuant to the Related
Agreements, there are no outstanding options, warrants, rights (including
conversion or preemptive rights and rights of first refusal), proxy or
shareholder agreements, or agreements of any kind for the purchase or
acquisition from the Company of any of its securities. When issued in compliance
with the provisions of this Agreement and the Restated Certificate, the Shares
and the Conversion Shares will be validly issued, fully paid and nonassessable,
and will be free of any liens or encumbrances; provided, however, that the
Shares and the Conversion Shares may be subject to restrictions on transfer
under state and/or federal securities laws as set forth herein or as otherwise
required by such laws at the time a transfer is proposed.

         3.3. AUTHORIZATION; BINDING OBLIGATIONS. All corporate action on the
part of the Company, its officers, directors and shareholders necessary for the
authorization of this Agreement and the Related Agreements, the performance of
all obligations of the Company hereunder and thereunder at the Closing and the
authorization, sale, issuance and delivery of the Shares pursuant hereto and the
Conversion Shares pursuant to the Restated Certificate has been taken or will be
taken prior to the Closing. The Agreement and the Related Agreements, when
executed and delivered, will be valid and binding obligations of the Company
enforceable in accordance with their terms, except (i) as limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other laws of general
application affecting enforcement of creditors' rights; (ii) general principles
of equity that restrict the availability of equitable remedies; and (iii) to the
extent that the enforceability of the indemnification provisions in Section 2.9
of the Investor Rights Agreement may be limited by applicable laws. The sale of
the Shares and the subsequent conversion of the Shares into Conversion Shares
are not and will not be subject to any preemptive rights or rights of first
refusal that have not been properly waived or complied with.

         3.4. FINANCIAL STATEMENTS. The Company has delivered to each Purchaser
(i) its reviewed but not audited balance sheet as at December 31, 1995 and
reviewed but not audited statement of income and cash flows for the twelve
months ending December 31, 1995 and (ii) its unaudited balance sheet as at June
30, 1996 (the "Statement Date") and unaudited consolidated statement of income
and cash flows for the six month period ending on the Statement Date

complete and correct in all material respects, have been prepared in accordance
with generally accepted accounting principles applied on a consistent basis
throughout the periods indicated, except as disclosed therein, and present
fairly the financial condition and position of the Company as of December 31,
1995 and the Statement Date; provided, however, that the financial statements as
of the Statement Date are subject to normal recurring year-end audit adjustments
(which are not expected to be material), and do not contain all footnotes
required under generally accepted accounting principles.

         3.5. LIABILITIES. The Company has no material liabilities and, to the
best of its knowledge, knows of no material contingent liabilities not disclosed
in the Financial Statements, except current liabilities incurred in the ordinary
course of business subsequent to the Statement Date which have not been, either
in any individual case or in the aggregate, materially adverse.

                  (c) The Company has not (i) declared or paid any dividends, or

excess of $10,000 or, in the case of indebtedness and/or liabilities
individually less than $10,000, in excess of $25,000 in the aggregate, (iii)
made any loans or advances to any person, other than ordinary advances for

                  (d) For the purposes of subsections (b) and (c) above, all
indebtedness, liabilities, agreements, understandings, instruments, contracts
and proposed transactions involving the same person or entity (including persons

         3.9. TITLE TO PROPERTIES AND ASSETS; LIENS, ETC. The Company has good
and marketable title to its properties and assets, including the properties and
assets reflected in the most recent balance sheet included in the Financial

mortgage, pledge, lien, lease, encumbrance or charge, other than (i) those
resulting from taxes which have not yet become delinquent, (ii) minor liens and
encumbrances which do not materially detract from the value of the property
subject thereto or materially impair the operations of the Company, and (iii)
those that have otherwise arisen in the ordinary course of business. All
facilities, machinery, equipment, fixtures, vehicles and other properties owned,
leased or used by the Company are in good operating condition and repair and are
reasonably fit and usable for the purposes for which they are being used.

         3.10. PATENTS AND TRADEMARKS. The Company owns or possesses sufficient
legal rights to all patents, trademarks, service marks, trade names, copyrights,
trade secrets, information and other proprietary rights and processes necessary
for its business as now conducted and as proposed to be conducted, without any
known infringement of the rights of others. There are no outstanding options,
licenses or agreements of any kind relating to the foregoing, nor is the Company
bound by or a party to any options, licenses or agreements of any kind with
respect to the patents, trademarks, service marks, trade names, copyrights,
trade secrets, licenses, information and other proprietary rights and processes
of any other person or entity other than such licenses or agreements arising
from the purchase of "off the shelf" or standard products. The Company has not
received any communications alleging that the Company has violated or, by
conducting its business as proposed, would violate any of the patents,
trademarks, service marks, trade names, copyrights or trade secrets or other
proprietary rights of any other person or entity. The Company is not aware that
any of its employees is obligated under any contract (including licenses,
covenants or commitments of any nature) or other agreement, or subject to any
judgment, decree or order of any court or administrative agency, that would
interfere with their duties to the Company or that would conflict with the
Company's business as proposed to be conducted. Neither the execution nor
delivery of this Agreement, nor the carrying on of the Company's business by the
employees of the Company, nor the conduct of the Company's business as proposed,
will, to the Company's knowledge, conflict with or result in a breach of the
terms, conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any employee is now obligated. The Company
does not believe it is or will be necessary to utilize any inventions, trade
secrets or proprietary information of any of its employees made prior to their
employment by the Company, except for inventions, trade secrets or proprietary
information that have been assigned to the Company.

         3.11. COMPLIANCE WITH OTHER INSTRUMENTS. The Company is not in
violation or default of any term of its Restated Certificate or Bylaws, or of
any provision of any mortgage, indenture, contract, agreement, instrument or
contract to which it is party or by which it is bound or of any judgment,
decree, order, writ or, to its knowledge, any statute, rule or regulation
applicable to the Company which would materially and adversely affect the
business, assets, liabilities, financial condition, operations or prospects of
the Company. The execution, delivery, and performance of and compliance with
this

                                       7.
<PAGE>   12

Agreement, and the Related Agreements, and the issuance and sale of the Shares
pursuant hereto and of the Conversion Shares pursuant to the Restated Articles,
will not, with or without the passage of time or giving of notice, result in any
such material violation, or be in conflict with or constitute a default under
any such term, or result in the creation of any mortgage, pledge, lien,
encumbrance or charge upon any of the properties or assets of the Company or the
suspension, revocation, impairment, forfeiture or nonrenewal of any permit
license, authorization or approval applicable to the Company, its business or
operations or any of its assets or properties.

         3.12. LITIGATION. There is no action, suit, proceeding or investigation
pending or to the Company's knowledge currently threatened against the Company
that questions the validity of this Agreement, or the Related Agreements or the
right of the Company to enter into any of such agreements, or to consummate the
transactions contemplated hereby or thereby, or which might result, either
individually or in the aggregate, in any material adverse change in the assets,
condition, affairs or prospects of the Company, financially or otherwise, or any
change in the current equity ownership of the Company, nor is the Company aware
that there is any basis for the foregoing. The foregoing includes, without
limitation, actions pending or threatened (or any basis therefor known to the
Company) involving the prior employment of any of the Company's employees, their
use in connection with the Company's business of any information or techniques
allegedly proprietary to any of their former employers, or their obligations
under any agreements with prior employers. The Company is not a party or subject
to the provisions of any order, writ, injunction, judgment or decree of any
court or government agency or instrumentality. There is no action, suit,
proceeding or investigation by the Company currently pending or which the
Company intends to initiate.

         3.13. TAX RETURNS AND PAYMENTS. The Company has timely filed all tax
returns (federal, state and local) required to be filed by it. All taxes shown
to be due and payable on such returns, any assessments imposed, and to the
Company's knowledge all other taxes due and payable by the Company on or before
the Closing have been paid or will be paid prior to the time they become
delinquent. The Company has not been advised (i) that any of its returns,
federal, state or other, have been or are being audited as of the date hereof,
or (ii) of any deficiency in assessment or proposed judgment to its federal,
state or other taxes. The Company has no knowledge of any liability of any tax
to be imposed upon its properties or assets as of the date of this Agreement
that is not adequately provided for.

         3.14. EMPLOYEES. The Company has no collective bargaining agreements
with any of its employees. There is no labor union organizing activity pending
or, to the Company's knowledge, threatened with respect to the Company. No
employee has any agreement or contract, written or verbal, regarding his
employment. The Company is not a party to or bound by any currently effective
employment contract, deferred compensation arrangement, bonus plan, incentive
plan, profit sharing plan, retirement agreement or other employee compensation
plan or agreement. To the Company's knowledge, no employee of the Company, nor
any consultant with whom the Company has contracted, is in violation of any term
of any employment contract, proprietary information agreement or any other
agreement relating to the right of any such individual to be employed by, or to
contract with, the Company because of the nature of the business to be conducted
by the Company; and to the Company's knowledge the continued employment by the
Company of its present employees, and the performance of the Company's contracts
with its independent contractors, will not result in any such violation. The
Company has not received any notice alleging that any such violation has
occurred. No employee of the Company has been granted the right to continued
employment by the Company or to any material compensation following termination
of employment with the Company. The Company is not aware that any officer or key
employee, or that any group of key employees, intends to terminate their
employment

                                       8.
<PAGE>   13

with the Company, nor does the Company have a present intention to terminate the
employment of any officer, key employee or group of key employees.

         3.15. NON-COMPETITION AND NON-DISCLOSURE AGREEMENTS. Each former and
current employee, officer and consultant of the Company has executed a
Non-Competition and Non-Disclosure Agreement in one of the forms attached as
Exhibit K hereto.

         3.16. OBLIGATIONS OF MANAGEMENT. Each officer of the Company is
currently devoting one hundred percent (100%) of his business time to the
conduct of the business of the Company. The Company is not aware of any officer
or key employee of the Company planning to work less than full time at the
Company in the future.

         3.17. REGISTRATION RIGHTS. Except as required pursuant to the Investor
Rights Agreement, the Company is presently not under any obligation, and has not
granted any rights, to register (as defined in Section 1.1 of the Investor
Rights Agreement) any of the Company's presently outstanding securities or any
of its securities that may hereafter be issued.

         3.18. COMPLIANCE WITH LAWS; PERMITS. To its knowledge, the Company is
not in violation of any applicable statute, rule, regulation, order or
restriction of any domestic or foreign government or any instrumentality or
agency thereof in respect of the conduct of its business or the ownership of its
properties which violation would materially and adversely affect the business,
assets, liabilities, financial condition, operations or prospects of the
Company. No governmental orders, permissions, consents, approvals or
authorizations are required to be obtained and no registrations or declarations
are required to be filed in connection with the execution and delivery of this
Agreement and the issuance of the Shares or the Conversion Shares, except such
as has been duly and validly obtained or filed, or with respect to any filings
that must be made after the Closing, as will be filed in a timely manner. The
Company has all franchises, permits, licenses and any similar authority
necessary for the conduct of its business as now being conducted by it, the lack
of which could materially and adversely affect the business, properties,
prospects or financial condition of the Company and believes it can obtain,
without undue burden or expense, any similar authority for the conduct of its
business as planned to be conducted.

         3.19. ENVIRONMENTAL AND SAFETY LAWS. To its knowledge, the Company is
not in violation of any applicable statute, law or regulation relating to the
environment or occupational health and safety, and to its knowledge, no material
expenditures are or will be required in order to comply with any such existing
statute, law or regulation.

         3.20. OFFERING VALID. Assuming the accuracy of the representations and
warranties of the Purchasers contained in Section 4.2 hereof, the offer, sale
and issuance of the Shares and the Conversion Shares will be exempt from the
registration requirements of the Securities Act of 1933, as amended (the
"Securities Act") and will have been registered or qualified (or are exempt from
registration and qualification) under the registration, permit or qualification
requirements of all applicable state securities laws. Neither the Company nor
any agent on its behalf has solicited or will solicit any offers to sell or has
offered to sell or will offer to sell all or any part of the Shares to any
person or persons so as to bring the sale of such Shares by the Company within
the registration provisions of the Securities Act.

         3.21. FULL DISCLOSURE. This Agreement, the Exhibits hereto, the Related
Agreements and all other documents delivered by the Company to Purchasers or
their attorneys or agents in connection

                                       9.

herewith or therewith or with the transactions contemplated hereby or thereby,
do not contain any untrue statement of a material fact nor, to the Company's
knowledge, omit to state a material fact necessary in order to make the
statements contained herein or therein not misleading. The Business Plan, dated
March 25, 1996 (the "Business Plan") provided to each of the Purchasers was
prepared by the management of the Company in a good faith effort to describe the
Company's proposed business and products and the markets therefore. The
assumptions applied in preparing the Business Plan appeared reasonable to
management as of the date thereof and as of the date hereof; however, there is
no assurance that these assumptions will prove to be valid or that the
objectives set forth in the Business Plan will be achieved. To the Company's
knowledge, there are no facts which (individually or in the aggregate)
materially adversely affect the business, assets, liabilities, financial
condition, prospects or operations of the Company that have not been set forth
in the Agreement, the Exhibits hereto, the Related Agreements or in other
documents delivered to Purchasers or their attorneys or agents in connection
herewith.

         3.22. QUALIFIED SMALL BUSINESS. The Company represents and warrants to
the Purchasers that, to the best of its knowledge, the Shares should qualify as
"Qualified Small Business Stock" as defined in Section 1202(c) of the Internal
Revenue Code of 1986, as amended (the "Code") as of the date hereof. The Company
will use reasonable efforts to comply with the reporting and record keeping
requirements of Section 1202 of the Code, any regulations promulgated thereunder
and any similar state laws and regulations, and agrees not to repurchase any
stock of the Company if such repurchase would cause such Shares not to so
qualify as "Qualified Small Business Stock."

         3.23. MINUTE BOOKS. The minute books of the Company provided to the
Purchasers contain a complete summary of all meetings of directors and
shareholders since the time of incorporation.

         3.24. SECTION 83(b) ELECTIONS. To the Company's knowledge, all
elections and notices permitted by Section 83(b) of the Internal Revenue Code
and any analogous provisions of applicable state tax laws have been timely filed
by all employees who have purchased shares of the Company's common stock under
agreements that provide for the vesting of such shares.

         3.25. REAL PROPERTY HOLDING CORPORATION. The Company is not a real
property holding corporation within the meaning of Internal Revenue Code Section
897(c)(2) and any regulations promulgated thereunder.

         3.26. INSURANCE. The Company has or will obtain promptly following the
Initial Closing fire and casualty insurance policies with coverage customary for
companies similarly situated to the Company.

         3.27. INVESTMENT COMPANY ACT. The Company is not an "investment
company", or a company "controlled" by an "investment", within the meaning of
the Investment Company Act of 1940, as amended.

SECTION 4.  REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS.

         Each Purchaser hereby represents and warrants to the Company as of each

the Company set forth in this Agreement):

                                      10.

         4.1. REQUISITE POWER AND AUTHORITY. Purchaser has all necessary power
and authority under all applicable provisions of law to execute and deliver this
Agreement and the Related Agreements and to carry out their provisions. All
action on Purchaser's part required for the lawful execution and delivery of
this Agreement and the Related Agreements have been or will be effectively taken
prior to the Closing. Upon their execution and delivery, this Agreement and the
Related Agreements will be valid and binding obligations of Purchaser,
enforceable in accordance with their terms, except (i) as limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other laws of general
application affecting enforcement of creditors' rights, (ii) general principles
of equity that restrict the availability of equitable remedies, and (iii) to the
extent that the enforceability of the indemnification provisions of Section 2.9
of the Investor Rights Agreement may be limited by applicable laws.

         4.2. INVESTMENT REPRESENTATIONS. Purchaser understands that the Shares,
the Warrant Shares and the Conversion Shares have not been registered under the
Securities Act. Purchaser also understands that the Shares are being offered and
sold pursuant to an exemption from registration contained in the Securities Act
based in part upon Purchaser's representations contained in the Agreement.
Purchaser hereby represents and warrants as follows:

                  (a) PURCHASER BEARS ECONOMIC RISK. Purchaser has substantial
experience in evaluating and investing in private placement transactions of
securities in companies similar to the Company so that it is capable of
evaluating the merits and risks of its investment in the Company and has the
capacity to protect its own interests. Purchaser must bear the economic risk of
this investment indefinitely unless the Shares (or the Warrant Shares or
Conversion Shares) are registered pursuant to the Securities Act, or an
exemption from registration is available. Purchaser understands that the Company
has no present intention of registering the Shares, the Warrant Shares, the
Conversion Shares or any shares of its Common Stock. Purchaser also understands
that there is no assurance that any exemption from registration under the
Securities Act will be available and that, even if available, such exemption may
not allow Purchaser to transfer all or any portion of the Shares, the Warrant
Shares or the Conversion Shares under the circumstances, in the amounts or at
the times Purchaser might propose.

                  (b) ACQUISITION FOR OWN ACCOUNT. Purchaser is acquiring the
Shares and the Conversion Shares for Purchaser's own account for investment
only, and not with a view towards their distribution.

                  (c) PURCHASER CAN PROTECT ITS INTEREST. Purchaser represents
that by reason of its, or of its management's, business or financial experience,
Purchaser has the capacity to protect its own interests in connection with the
transactions contemplated in this Agreement, and the Related Agreements.
Further, Purchaser is aware of no publication of any advertisement in connection
with the transactions contemplated in the Agreement.

                  (d) ACCREDITED INVESTOR. Purchaser represents that it is an
accredited investor within the meaning of Regulation D under the Securities Act.

                  (e) COMPANY INFORMATION. Purchaser has received and read the
Financial Statements and Business Plan and has had an opportunity to discuss the
Company's business, management and financial affairs with directors, officers
and management of the Company and has had the opportunity to review the
Company's operations and facilities. Purchaser has also had the opportunity to
ask questions of and receive answers from, the Company and its management
regarding the terms and conditions of this investment.

<PAGE>   16

                  (f) RULE 144. Purchaser acknowledges and agrees that the
Shares, and, if issued, the Warrant Shares and the Conversion Shares must be
held indefinitely unless they are subsequently registered under the Securities
Act or an exemption from such registration is available. Purchaser has been
advised or is aware of the provisions of Rule 144 promulgated under the
Securities Act, which permits limited resale of shares purchased in a private
placement subject to the satisfaction of certain conditions, including, among
other things: the availability of certain current public information about the
Company, the resale occurring not less than two years after a party has
purchased and paid for the security to be sold, the sale being through an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934, as
amended) and the number of shares being sold during any three-month period not
exceeding specified limitations.

                  (g) RESIDENCE. If the Purchaser is an individual, then the
Purchaser resides in the state or province identified in the address of the
Purchaser set forth on Exhibit A; if the Purchaser is a partnership,
corporation, limited liability company or other entity, then the office or

and rights of first refusal), proxy or shareholder agreements, or agreements of
any kind for the purchase or acquisition from the Company of any of its
securities. When issued in compliance with the provisions of this Agreement and
the Restated Certificate, the Shares and the Conversion Shares will be validly

SECTION 3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

     Except as set forth on the Schedule of Exceptions attached hereto as
Exhibit C, the Company hereby represents and warrants to each Purchaser as
follows:

     3.1. ORGANIZATION, GOOD STANDING AND QUALIFICATION. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware. The Company has all requisite corporate power and
authority to own and operate its properties and assets, to execute and deliver
this Agreement, the Amended and Restated Investor Rights Agreement in the form
attached hereto as Exhibit D (the "Investor Rights Agreement"), and the Amended
and Restated Shareholders Agreement attached hereto as Exhibit E (the
"Shareholders Agreement") (collectively, the "Related Agreements"), to issue and
sell the Shares and the Conversion Shares and to carry out the provisions of
this Agreement, the Related Agreements and the Restated Certificate and to carry
on its business as presently conducted and as presently proposed to be
conducted. The Company is duly qualified and is authorized to do business and is
in good standing as a foreign corporation in Colorado and all other
jurisdictions in which the nature of its activities and of its properties (both
owned and leased) makes such qualification necessary, except for those
jurisdictions in which failure to do so would not have a material adverse effect
on the Company or its business. The Company owns no equity securities of any
other corporation, limited partnership or similar entity. The Company is not a
participant in any joint venture, partnership or similar arrangement.

     3.2. CAPITALIZATION; VOTING RIGHTS. The authorized capital stock of the
Company, immediately prior to the Closing, will consist of (x) 15,000,000 shares
of Common Stock, 1,546,377 shares of which are issued and outstanding and
2,130,000 shares of which are reserved for future issuance to key employees and
consultants pursuant to the Company's 1995 Stock Option Plan, of which 974,425
remain available for issuance under such plan, and (y) 6,519,955 shares of
Preferred Stock, 337,420 of which are designated Series A Preferred Stock,
189,630 shares of which are issued and outstanding, 3,132,535 of which are
designated Series B Preferred Stock, 3,118,785 shares of which are issued and
outstanding, and 3,050,000 of which are designated Series C Preferred Stock,
none of which are issued and outstanding. All issued and outstanding shares of
the Company's Common Stock and Preferred Stock (i) have been duly authorized and
validly issued to the persons listed on Exhibit F hereto, (ii) are fully paid
and nonassessable, and (iii) were issued in compliance with all applicable state
and federal laws concerning the issuance of securities. The rights, preferences,
privileges and restrictions of the Shares are as stated in the Restated
Certificate and are valid, binding and enforceable in accordance with applicable
law. The Conversion Shares have been duly and validly reserved for issuance.
Other than as set forth on Exhibit F, and except as may be granted pursuant to
the Related Agreements, there are no outstanding options, warrants, rights
(including conversion or preemptive rights and rights of first refusal), proxy
or shareholder agreements, or agreements of any kind for the purchase or
acquisition from the Company of any of its securities. There are no rights of
first refusal with respect to the issuance of the Shares and the subsequent
conversion of the Shares into Conversion Shares that have not been complied with
or for which waivers have not been obtained. When issued in compliance with the
provisions of this Agreement and the Restated Certificate, the Shares and the
Conversion Shares will be validly issued, fully paid and nonassessable with no
personal liability attaching to the ownership thereof, and will be free of any
liens or encumbrances; provided, however, that the Shares and the Conversion
Shares may be subject to restrictions on transfer under state and/or federal
securities laws as set forth herein or as otherwise required by such laws at the
time a transfer is proposed. The Company has no obligation to purchase, acquire
or redeem any of its outstanding securities. After giving effect to the
transactions contemplated hereby, all officers, directors and holders of one
percent (1%) of the

                                       2.
<PAGE>   7

outstanding capital stock of the Company are subject to a market stand-off
agreement in substantially the form contained in Section 2.13 of the Investor
Rights Agreement.

     3.3. AUTHORIZATION; BINDING OBLIGATIONS. All corporate action on the part
of the Company, its officers, directors and stockholders necessary for the
authorization of this Agreement and the Related Agreements, the performance of
all obligations of the Company hereunder and thereunder at the Closing and the
authorization, sale, issuance and delivery of the Shares pursuant hereto and the
Conversion Shares pursuant to the Restated Certificate has been taken or will be
taken prior to the Closing. The Agreement and the Related Agreements, when
executed and delivered, will be legal, valid and binding obligations of the
Company enforceable in accordance with their terms, except (i) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other laws of
general application affecting enforcement of creditors' rights; (ii) general
principles of equity that restrict the availability of equitable remedies; and
(iii) to the extent that the enforceability of the indemnification provisions in
Section 2.9 of the Investor Rights Agreement may be limited by applicable laws.

     3.4. FINANCIAL STATEMENTS. The Company has delivered to each Purchaser (i)
its unaudited balance sheet as at December 31, 1996 and unaudited statement of
income and cash flows for the twelve months ending December 31, 1996 and (ii)
its unaudited balance sheet as at July 31, 1997 (the "Statement Date") and
unaudited consolidated statement of income and cash flows for the seven month
period ending on the Statement Date (collectively, the "Financial Statements"),
copies of which are attached hereto as Exhibit G. The Financial Statements,
together with the notes thereto, are complete and correct in all material
respects, have been prepared in accordance with generally accepted accounting
principles applied on a consistent basis throughout the periods indicated,
except as disclosed therein, and present fairly the financial condition and
position of the Company as of December 31, 1996 and the Statement Date;
provided, however, that the financial statements as of the Statement Date are
subject to normal recurring year-end audit adjustments (which are not expected
to be material), and do not contain all footnotes required under generally
accepted accounting principles.

     3.5. LIABILITIES. The Company has no material liabilities and, to the best
of its knowledge, knows of no material contingent liabilities not disclosed in
the Financial Statements, except current liabilities incurred in the ordinary
course of business subsequent to the Statement Date which have not been, either
in any individual case or in the aggregate, materially adverse.

     3.6. AGREEMENTS; ACTION.

          (a) Except for agreements explicitly contemplated hereby and
agreements between the Company and its employees with respect to the sale of the
Company's Common Stock, there are no agreements, understandings or proposed
transactions between the Company and any of its officers, directors, affiliates
or any affiliate thereof.

          (b) There are no agreements, understandings, instruments, contracts,
proposed transactions, judgments, orders, writs or decrees to which the Company
is a party or to its knowledge by which it is bound which may involve (i)
obligations (contingent or otherwise) of, or payments to, the Company in excess
of $25,000 or (ii) the license of any patent, copyright, trade secret or other
proprietary right to or from the Company (other than licenses arising from the
purchase of "off the shelf" or other standard products), or (iii) provisions
restricting or affecting the development, manufacture or distribution of the
Company's products or services, or (iv) indemnification by the Company with
respect

                                       3.
<PAGE>   8

to infringements of proprietary rights (other than indemnification obligations
arising from purchase or sale agreements entered into in the ordinary course of
business).

          (c) The Company has not (i) declared or paid any dividends, or
authorized or made any distribution upon or with respect to any class or series
of its capital stock, (ii) incurred any indebtedness which is currently
outstanding for money borrowed or any other liabilities (other than with respect
to dividend obligations, distributions, indebtedness and other obligations
incurred in the ordinary course of business or as disclosed in the Financial
Statements) individually in excess of $25,000 or, in the case of indebtedness
and/or liabilities individually less than $25,000, in excess of $50,000 in the
aggregate, (iii) made any loans or advances to any person, other than ordinary
advances for travel expenses, or (iv) sold, exchanged or otherwise disposed of
any of its assets or rights, other than the sale of its inventory in the
ordinary course of business.

          (d) For the purposes of subsections (b) and (c) above, all
indebtedness, liabilities, agreements, understandings, instruments, contracts
and proposed transactions involving the same person or entity (including persons
or entities the Company has reason to believe are affiliated therewith) shall be
aggregated for the purpose of meeting the individual minimum dollar amounts of
such subsections.

          (e) The Company has performed all material obligations required to be
performed by it as of the date hereof under any material agreement to which the
Company is a party or by which it is bound. There are no agreements not
otherwise disclosed that could reasonably be expected to materially and
adversely affect the Company. No party to any such material contract has
notified the Company with a claim to the effect that the Company has failed to
perform an obligation thereunder. To the knowledge of the Company, there is no
plan, intention or indication of any contracting party to such material contract
to cause the termination, cancellation or modification of such material contract
or to reduce or otherwise change its activity thereunder so as to materially and
adversely effect the benefits derived as expected to be derived therefrom by the
Company.

          (f) The Company has not engaged in the past three (3) months in any
discussion (i) with any representative of any corporation or corporations
regarding the consolidation or merger of the Company with or into any such
corporation or corporations, (ii) with any corporation, partnership, association
or other business entity or any individual regarding the sale, conveyance or
disposition of all or substantially all of the assets of the Company, or a
transaction or series of related transactions in which more than fifty percent
(50%) of the voting power of the Company is disposed of, or (iii) regarding any
other form of acquisition, liquidation, dissolution or winding up of the
Company.

Company to officers, directors or employees of the Company other than (a) for
payment of salary for services rendered, (b) reimbursement for reasonable
expenses incurred on behalf of the Company, (c) for other standard employee
benefits made generally available to all employees (including stock option
agreements outstanding under any stock option plan approved by the Board of
Directors of the Company). None of the officers or directors who are employees
of the Company, or any members of their immediate families, are indebted to the
Company or have any direct or indirect ownership interest in any firm or
corporation with which the Company is affiliated or with which the Company has a
business relationship, or any firm or corporation which competes with the
Company, except that officers, directors and/or stockholders of the Company may
own stock in publicly traded companies which may compete with the Company. No
officer or director who is an employee of the Company, or any member of their
immediate families, is, directly or indirectly, interested in any material
contract with the Company (other

                                       4.
<PAGE>   9

than such contracts as relate to any such person's ownership of capital stock or
other securities of the Company). Except as may be disclosed in the Financial
Statements, the Company is not a guarantor or indemnitor of any indebtedness of
any other person, firm or corporation.

     3.8. CHANGES. Since the Statement Date, there has not been to the Company's
knowledge:

          (a) Any change in the assets, liabilities, financial condition or
operations of the Company from that reflected in the Financial Statements, other
than changes in the ordinary course of business, none of which individually or
in the aggregate has had or is expected to have a material adverse effect on
such assets, liabilities, financial condition or operations of the Company;

          (b) Any resignation or termination of any key officers of the Company;
and the Company, to the best of its knowledge, does not know of the impending

          (d) Any damage, destruction or loss, whether or not covered by
insurance, materially and adversely affecting the properties, business or
prospects or financial condition of the Company;

          (e) Any waiver by the Company of a valuable right or of a material
debt owed to it;

          (f) Any direct or indirect loans made by the Company to any
stockholder, employee, officer or director of the Company, other than advances
made in the ordinary course of business;

          (g) Any material change in any compensation arrangement or agreement
with any employee, officer, director or stockholder;

          (h) Any declaration or payment of any dividend or other distribution
of the assets of the Company or any repurchase or redemption of any outstanding
security of the Company;

          (i) Any labor organization activity;

          (j) Any debt, obligation or liability incurred, assumed or guaranteed
by the Company, except those for immaterial amounts and for current liabilities
incurred in the ordinary course of business;

          (k) Any sale, assignment or transfer of any patents, trademarks,
copyrights, trade secrets or other intangible assets;

capital stock of the Company), other than options granted pursuant to the
Company's 1995 Stock Option Plan;

                                       5.
<PAGE>   10

          (m) Any change in any material agreement to which the Company is a
party or by which it is bound which materially and adversely affects the
business, assets, liabilities, financial condition, operations or prospects of
the Company, including compensation agreements with the Company's employees; or

          (n) Any other event or condition of any character that, either
individually or cumulatively, has materially and adversely affected the
business, assets, liabilities, financial condition, operations or prospects of
the Company.

     3.9. TITLE TO PROPERTIES AND ASSETS; LIENS, ETC. The Company has good and
marketable title to its properties and assets, including the properties and
assets reflected in the most recent balance sheet included in the Financial
Statements, and good title to its leasehold estates, in each case subject to no
mortgage, pledge, lien, lease, encumbrance or charge, other than (i) those
resulting from taxes which have not yet become delinquent and (ii) minor liens
and encumbrances which do not materially detract from the value of the property
subject thereto or materially impair the operations of the Company. All
facilities, machinery, equipment, fixtures, vehicles and other properties owned,
leased or used by the Company are in good operating condition and repair and are
reasonably fit and usable for the purposes for which they are being used.

     3.10. PATENTS AND TRADEMARKS. The Company owns or possesses sufficient
legal rights to all patents, and, to the best of its knowledge after reasonable
investigation, all trademarks, service marks, trade names, copyrights, trade
secrets, information and other proprietary rights and processes necessary for
its business as now conducted and as proposed to be conducted, without any known
infringement of the rights of others. Set forth on the Schedule of Exceptions is
a list of the Company's patents, pending patent applications, registered
trademarks and pending trademark applications. There are no outstanding options,
licenses or agreements of any kind relating to the foregoing, nor is the Company
bound by or a party to any options, licenses or agreements of any kind with
respect to the patents, trademarks, service marks, trade names, copyrights,
trade secrets, licenses, information and other proprietary rights and processes
of any other person or entity other than such licenses or agreements arising
from the purchase of "off the shelf" or standard products. The Company has not
received any communications alleging that the Company has violated or, by
conducting its business as proposed, would violate any of the patents,
trademarks, service marks, trade names, copyrights or trade secrets or other
proprietary rights of any other person or entity, nor to the Company's
knowledge, is there a basis for any such claim. The Company is not aware that
any of its employees is obligated under any contract (including licenses,
covenants or commitments of any nature) or other agreement, or subject to any
judgment, decree or order of any court or administrative agency, that would
interfere with their duties to the Company or that would conflict with the
Company's business as proposed to be conducted. Neither the execution nor
delivery of this Agreement, nor the carrying on of the Company's business by the
employees of the Company, nor the conduct of the Company's business as proposed,
will, to the Company's knowledge, conflict with or result in a breach of the
terms, conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any employee is now obligated. The Company
does not believe it is or will be necessary to utilize any inventions, trade
secrets or proprietary information of any of its employees made prior to their
employment by the Company, except for inventions, trade secrets or proprietary
information that have been assigned to the Company.

     3.11. COMPLIANCE WITH OTHER INSTRUMENTS. The Company is not in violation or
default of any term of its Restated Certificate or Bylaws, or of any provision
of any mortgage, indenture, agreement, instrument or contract to which it is
party or by which it is bound or of any judgment, decree,

                                       6.
<PAGE>   11

order, writ or, to its knowledge, any statute, rule or regulation applicable to
the Company which would materially and adversely affect the business, assets,
liabilities, financial condition, operations or prospects of the Company. The
execution, delivery, and performance of and compliance with this Agreement, and
the Related Agreements, and the issuance and sale of the Shares pursuant hereto
and of the Conversion Shares pursuant to the Restated Articles, will not, with
or without the passage of time or giving of notice, result in any such material
violation, or be in conflict with or constitute a default under any such term,
or result in the creation of any mortgage, pledge, lien, encumbrance or charge
upon any of the properties or assets of the Company or the suspension,
revocation, impairment, forfeiture or nonrenewal of any permit license,
authorization or approval applicable to the Company, its business or operations
or any of its assets or properties.

     3.12. LITIGATION. There is no action, suit, proceeding or investigation
pending or to the Company's knowledge currently threatened against the Company
that questions the validity of this Agreement, or the Related Agreements or the
right of the Company to enter into any of such agreements, or to consummate the
transactions contemplated hereby or thereby, or which might result, either
individually or in the aggregate, in any material adverse change in the assets,
condition, affairs or prospects of the Company, financially or otherwise, or any
change in the current equity ownership of the Company, nor is the Company aware
that there is any basis for the foregoing. The foregoing includes, without
limitation, actions pending or threatened (or any basis therefor known to the
Company) involving the prior employment of any of the Company's employees, their
use in connection with the Company's business of any information or techniques
allegedly proprietary to any of their former employers, or their obligations
under any agreements with prior employers. The Company is not a party or subject
to the provisions of any order, writ, injunction, judgment or decree of any
court or government agency or instrumentality. There is no action, suit,
proceeding or investigation by the Company currently pending or which the
Company intends to initiate.

     3.13. TAX RETURNS AND PAYMENTS. The Company has timely filed all tax
returns (federal, state and local) required to be filed by it. All taxes shown
to be due and payable on such returns, any assessments imposed, and to the
Company's knowledge all other taxes due and payable by the Company on or before
the Closing have been paid or will be paid prior to the time they become
delinquent. The Company has not been advised (i) that any of its returns,
federal, state or other, have been or are being audited as of the date hereof,
or (ii) of any deficiency in assessment or proposed judgment to its federal,
state or other taxes. The Company has no knowledge of any liability of any tax
to be imposed upon its properties or assets as of the date of this Agreement
that is not adequately provided for.

     3.14. EMPLOYEES. The Company has no collective bargaining agreements with
any of its employees. There is no labor union organizing activity pending or, to
the Company's knowledge, threatened with respect to the Company. No employee has
any agreement or contract, written or verbal, regarding his employment. The
Company is not a party to or bound by any currently effective employment
contract, deferred compensation arrangement, bonus plan, incentive plan, profit
sharing plan, retirement agreement or other employee compensation plan or
agreement. To the Company's knowledge, no employee of the Company, nor any
consultant with whom the Company has contracted, is in violation of any term of
any employment contract, proprietary information agreement or any other
agreement relating to the right of any such individual to be employed by, or to
contract with, the Company because of the nature of the business to be conducted
by the Company; and to the Company's knowledge the continued employment by the
Company of its present employees, and the performance of the Company's contracts
with its independent contractors, will not result in any such violation. The
Company has not received any notice alleging that any such violation has
occurred. No employee of the

                                       7.
<PAGE>   12

Company has been granted the right to continued employment by the Company or to
any material compensation following termination of employment with the Company.
The Company is not aware that any officer or key employee, or that any group of
key employees, intends to terminate their employment with the Company.

     3.15. NON-COMPETITION AND NON-DISCLOSURE AGREEMENTS. Each former and
current employee, officer and consultant of the Company has executed an
agreement regarding non-competition and/or non-disclosure of the Company's
confidential information in one of the forms attached as Exhibit H hereto, or an
agreement containing substantially the same restrictions as those set forth in
such forms.

     3.16. OBLIGATIONS OF MANAGEMENT. Each officer of the Company is currently
devoting one hundred percent (100%) of his or her business time to the conduct
of the business of the Company. The Company is not aware of any officer or key
employee of the Company planning to work less than full time at the Company in
the future.

     3.17. REGISTRATION RIGHTS. Except as required pursuant to the Investor
Rights Agreement, the Company is presently not under any obligation, and has not
granted any rights, to register (as defined in Section 1.1 of the Investor
Rights Agreement) any of the Company's presently outstanding securities or any
of its securities that may hereafter be issued.

     3.18. COMPLIANCE WITH LAWS; PERMITS. To its knowledge, the Company is not
in violation of any applicable statute, rule, regulation, order or restriction
of any domestic or foreign government or any instrumentality or agency thereof
in respect of the conduct of its business or the ownership of its properties
which violation would materially and adversely affect the business, assets,
liabilities, financial condition, operations or prospects of the Company. No
governmental orders, permissions, consents, approvals or authorizations are
required to be obtained and no registrations or declarations are required to be
filed in connection with the execution and delivery of this Agreement and the
issuance of the Shares or the Conversion Shares, except such as has been duly
and validly obtained or filed, or with respect to any filings that must be made
after the Closing, as will be filed in a timely manner. The Company has all
franchises, permits, licenses and any similar authority necessary for the
conduct of its business as now being conducted by it, the lack of which could
materially and adversely affect the business, properties, prospects or financial
condition of the Company and believes it can obtain, without undue burden or

SECTION 4. REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS.

     Each Purchaser hereby represents and warrants to the Company as of the
Closing as follows (such representations and warranties do not lessen or obviate
the representations and warranties of the Company set forth in this Agreement):

     4.1. REQUISITE POWER AND AUTHORITY. Purchaser has all necessary power and
authority under all applicable provisions of law to execute and deliver this
Agreement and the Related Agreements and to carry out their provisions. All
action on Purchaser's part required for the lawful execution and delivery of
this Agreement and the Related Agreements have been or will be effectively taken
prior to the Closing. Upon their execution and delivery, this Agreement and the
Related Agreements will be valid and binding obligations of Purchaser,
enforceable in accordance with their terms, except (i) as limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other laws of general
application affecting enforcement of creditors' rights, (ii) general principles
of equity that restrict the availability of equitable remedies, and (iii) to the
extent that the enforceability of the indemnification provisions of Section 2.9
of the Investor Rights Agreement may be limited by applicable laws.

     4.2. INVESTMENT REPRESENTATIONS. Purchaser understands that the Shares and
the Conversion Shares have not been registered under the Securities Act.
Purchaser also understands that the Shares are being offered and sold pursuant
to an exemption from registration contained in the Securities Act based in part
upon Purchaser's representations contained in the Agreement. Purchaser hereby
represents and warrants as follows:

          (a) PURCHASER BEARS ECONOMIC RISK. Purchaser has substantial
experience in evaluating and investing in private placement transactions of
securities in companies similar to the Company so that it is capable of
evaluating the merits and risks of its investment in the Company and has the
capacity to protect its own interests. Purchaser must bear the economic risk of
this investment indefinitely unless the Shares (or the Conversion Shares) are
registered pursuant to the Securities Act, or an exemption from registration is
available. Purchaser understands that the Company has no present intention of
registering the Shares, the Conversion Shares or any shares of its Common Stock.
Purchaser also understands that there is no assurance that any exemption from
registration under the Securities Act will be available and that, even if
available, such exemption may not allow Purchaser to transfer all or any portion
of the Shares or the Conversion Shares under the circumstances, in the amounts
or at the times Purchaser might propose.

          (b) ACQUISITION FOR OWN ACCOUNT. Purchaser is acquiring the Shares and
the Conversion Shares for Purchaser's own account for investment only, and not
with a view towards their distribution.

          (c) PURCHASER CAN PROTECT ITS INTEREST. Purchaser represents that by
reason of its, or of its management's, business or financial experience,
Purchaser has the capacity to protect its own interests in connection with the
transactions contemplated in this Agreement, and the Related Agreements.
Further, Purchaser is aware of no publication of any advertisement in connection
with the transactions contemplated in the Agreement.

          (d) ACCREDITED INVESTOR. Purchaser represents that it is an accredited
investor within the meaning of Regulation D under the Securities Act.

                                      10.
<PAGE>   15

          (e) COMPANY INFORMATION. Purchaser has received and read the Financial
Statements and has had an opportunity to discuss the Company's business,
management and financial affairs with directors, officers and management of the
Company and has had the opportunity to review the Company's operations and
facilities. Purchaser has also had the opportunity to ask questions of and
receive answers from, the Company and its management regarding the terms and
conditions of this investment.

          (f) RULE 144. Purchaser acknowledges and agrees that the Shares, and,
if issued, the Conversion Shares must be held indefinitely unless they are
subsequently registered under the Securities Act or an exemption from such
registration is available. Purchaser has been advised or is aware of the
provisions of Rule 144 promulgated under the Securities Act, which permits
limited resale of shares purchased in a private placement subject to the
satisfaction of certain conditions, including, among other things: the
availability of certain current public information about the Company, the resale
occurring not less than one year after a party has purchased and paid for the
security to be sold, the sale being through an unsolicited "broker's
transaction" or in transactions directly with a market maker (as said term is
defined under the Securities Exchange Act of 1934, as amended) and the number of
shares being sold during any three-month period not exceeding specified
limitations.

          (g) RESIDENCE. If the Purchaser is an individual, then the Purchaser
resides in the state or province identified in the address of the Purchaser set
forth on Exhibit A; if the Purchaser is a partnership, corporation, limited
liability company or other entity, then the office or offices of the Purchaser
in which its investment decision was made is located at the address or addresses
of the Purchaser set forth on Exhibit A.

     4.3. TRANSFER RESTRICTIONS. Each Purchaser acknowledges and agrees that the
Shares and, if issued, the Conversion Shares are subject to restrictions on
transfer as set forth in the Investor Rights Agreement.
