                             AMENDED AND RESTATED
                            MILLENNIA SYSTEMS, INC.
                      NONQUALIFIED STOCK OPTION AGREEMENT

     THIS STOCK OPTION AGREEMENT ("Agreement"), is entered into as of this _____
day of August, 2000, to be effective ________________ ("Date of Grant") by and
between MILLENNIA SYSTEMS, INC., a Virginia corporation (the "Company"), and the
person identified at the end of this Agreement as the optionee (the "Optionee").

     WHEREAS, the Board has granted the Optionee a stock option to purchase the
number of shares of the Company's common stock as set forth below;

     WHEREAS, the Company and the Optionee desire to enter into a written
agreement with respect to such option.

     NOW, THEREFORE, to enable and encourage stock ownership by employees, and
also in consideration of the mutual covenants contained herein, the parties
hereto agree as follows:

     1.  Grant of Option.  Subject to the terms, restrictions, limitations and
conditions stated herein, the Company hereby evidences its grant to the Optionee
of the right and option (the "Option") to purchase all or any part of the number
of shares of the Company's Class B nonvoting Common Stock, no par value per
share (the "Stock"), set forth on Schedule A attached hereto and incorporated
herein by reference.  The Option shall be exercisable in the amounts and at the
time specified on Schedule A.  The Option shall expire and shall not be
exercisable after the date specified on Schedule A or on such earlier date as
determined pursuant to Section 6, 7 or 8 hereof.  The Option evidenced hereby is
not intended to constitute an incentive stock option as such term is defined
under Section 422 of the Code.

     2.  Purchase Price.  The price per share to be paid by the Optionee for the
shares subject to this Option (the "Exercise Price") shall be as specified on

Schedule A.

     3.  Exercise Terms.  The Optionee must exercise the Option for at least the
lesser of 100 shares or the number of shares of purchasable Stock as to which
the Option remains unexercised.  In the event this Option is not exercised with
respect to all or any part of the shares subject to this Option prior to its
expiration, the shares with respect to which this Option was not exercised shall
no longer be subject to this Option.

     4.  Option Non-Transferable.  The Option is non-transferable other than by
will or the laws of descent and distribution or pursuant to a domestic relations
order.  During the lifetime of the Optionee, the Option shall be exercisable
only by such Optionee or the transferee under a domestic relations order (or by
such person's guardian or legal representative, should one be appointed).

     5.  Notice of Exercise of Option.  This Option may be exercised, in whole
or in part, by a written notice (in substantially the form of the Notice of
Exercise attached hereto as

<PAGE>

Schedule B) delivered or mailed to the Company as specified in Section 12 hereof
to the attention of the President/CEO or such other officer as the Company may
designate. Any such notice shall: (a) specify the number of shares of Stock
subject to the Option as to which the Option is being exercised, (b) contain
such information as may be reasonably required pursuant to Section 10 hereof,
and (c) be accompanied by a certified or cashier's check payable to the Company
in payment of the total Exercise Price applicable to such shares as provided
herein. Upon receipt of any such Notice of Exercise and accompanying payment,
and subject to the terms hereof, the Company agrees to issue stock certificates
for the number of shares specified in such notice registered in the name of the
person exercising this Option.

     In addition to and at the time of payment of the Exercise Price, the
Optionee shall pay to the Company in cash the full amount of any federal, state,
and local income, employment or other taxes required to be withheld from the
income of such Optionee as a result of such exercise and the Optionee agrees, as
a condition to receipt of the shares of Stock as to which the Option is being
exercised, to execute an agreement in such form and containing such terms and
conditions, including but not limited to, restrictions on the transfer of such
shares as shall be required by the Board of Directors of the Company in its sole
discretion.

     6.  Cessation of Service as Employee.

     (a) In the event of the termination of the Optionee's employment with the
Company, other than a termination that is either: (i) for Cause (as such term is
defined in the Employment Agreement between Company and Optionee), (ii) a
resignation on the part of the Optionee without written consent of the Company,
or (iii) on account of Optionee's death or disability, the number of shares set
forth in the Option shall be fully vested and the Optionee may exercise this
Option at any time within 3 months after such termination to the extent of the
number of shares set forth in Schedule A and not previously acquired by
Optionee; but in no event may such exercise occur after the Expiration Date
specified in Schedule A attached hereto.

     (b) In the event of a termination of the Optionee's employment with the
Company that is either: (i) for Cause; or (ii) a resignation on the part of the
Optionee without the written consent of the Company; or (iii) on account of the
death or disability of the Optionee, this Option, to the extent not previously
exercised, shall terminate 15 days after such termination and shall not
thereafter be or become exercisable; but in no event may such exercise occur
after the Expiration Date specified in Schedule A attached hereto.

     (c) Retirement of the Optionee at the end of the term during which he or
she reaches normal retirement date as prescribed from time to time by the
Company shall be deemed to be a termination of employment with consent for all
purposes of this Option.  For purposes of this Agreement, whether a termination
of employment by the Company constitutes termination for Cause shall be
determined in the sole discretion of the Board.  This Option does not confer
upon the Optionee any right with respect to continuance of service as an
employee of the Company.

     7.  Disabled Optionee.  In the event of termination of employment because
of the Optionee's becoming disabled, as defined in Code Section 22(e)(3) and
determined within the sole discretion of the Board, the Optionee (or his or her
personal representative) may exercise
<PAGE>

this Option at any time within 3 months after such termination to the extent of
the number of shares which were Purchasable hereunder at the date of such
termination; but in no event may such exercise occur after the Expiration Date
specified in Schedule A attached hereto.

     8.  Death of Optionee.  In the event of the Optionee's death while serving
as an employee of the Company, the Optionee's executor, personal representative
or the person(s) to whom the Option shall have been transferred by will or the
laws of descent and distribution, as the case may be, must exercise this Option,
if at all, at any time: (a) within 3 months following the Optionee's death or,
if earlier, (b) on or before the Expiration Date of this Option.  If the
Optionee was an employee of the Company at the time of death, this Option may be
so exercised to the extent of the number of shares that were Purchasable
hereunder at the date of death.  If the Optionee's employment terminated prior
to his or her death, this Option may be exercised only to the extent of the
number of shares covered by this Option which were Purchasable hereunder at the
date of termination.

     9.  Date of Grant.  This Option was granted by the Board on the date set
forth in Schedule A (the "Date of Grant").

     10. Compliance with Regulatory Matters.  The Optionee acknowledges that
the issuance of capital stock of the Company is subject to limitations imposed
by federal and state law and the Optionee hereby agrees that the Company shall
not be obligated to issue any shares of Stock upon exercise of this Option that
would cause the Company to violate any law or any rule, regulation, order or
consent decree of any regulatory authority (including without limitation the
Securities and Exchange Commission) having jurisdiction over the affairs of the
Company or may place restrictions (including but not limited to restrictions on
Optionee's rights to transfer such shares) on any shares of Stock issued upon
exercise of this Option in order to comply with or further assure compliance
with any such laws, rules, regulations, orders or consent decrees.  The Optionee
agrees that he or she will provide the Company with such information as is
reasonably requested by the Company or its counsel to determine whether the
issuance of Stock complies with the provisions described by this Section 10.

     11. Corporate Transaction.

     (a) If this Option is outstanding at the time of a Corporate Transaction
(as defined below) but not fully exercisable, this Option shall automatically
accelerate so that it will, immediately prior to the effective date of such
Corporate Transaction, become exercisable for all of the Stock at the time
subject to this Option and may be exercised for any or all of the Stock as fully
vested shares of Stock.  However, this Option shall not be accelerated if and to
the extent: (i) this Option is, in connection with the Corporate Transaction, to
be assumed by the successor corporation (or parent thereof), or (ii) this Option
is to be replaced with a cash incentive program of the successor corporation
which preserves the spread existing at the time of the Corporate Transaction on
the Stock for which this Option is not otherwise at that time exercisable (the
excess of the Fair Market Value as defined below of the Stock over the aggregate
Exercise Price payable for such shares) and provides for subsequent payout in
accordance with the same option exercise/vesting schedule set forth in the
Option.
<PAGE>

     (b)  Immediately following the Corporate Transaction, this Option shall
terminate and cease to be outstanding, except to the extent assumed by the
successor corporation (or parent thereof) in connection with the Corporate
Transaction.

     (c)  If this Option is assumed in connection with a Corporate Transaction,
then this Option shall be appropriately adjusted, immediately after such
Corporate Transaction, to apply to the number and class of securities which
would have been issuable to Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction, and appropriate adjustments shall also be made to the Exercise
Price, provided the aggregate Exercise Price under this Option shall remain the
same.

     (d)  This Agreement shall not in any way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

     (e)  For purposes of this Agreement, Fair Market Value per share of Common
Stock on any relevant date shall be determined in accordance with the following
provisions:

               (i)    If the Common Stock is at the time traded on the Nasdaq
National Market, then the Fair Market Value shall be deemed equal to the closing
selling price per share of Common Stock on the date in question, as the price is
reported by the National Association of Securities Dealers on the Nasdaq
National Market. If there is no closing selling price for the Common Stock on
the date in question, then the Fair Market Value shall be the closing selling
price on the last preceding date for which such quotation exists.

               (ii)   If the Common Stock is at the time listed on any Stock
Exchange, then the Fair Market Value shall be deemed equal to the closing
selling price per share of Common Stock on the date in question on the Stock
Exchange determined to be the primary market for the Common Stock, as such price
is officially quoted in the composite tape of transactions on such Exchange. If
there is no closing selling price for the Common Stock on the date in question,
then the Fair Market Value shall be the closing selling price on the last
preceding date for which such quotation exists.

     (f)  For purposes of this Agreement, Corporate Transaction shall mean
either of the following stockholder-approved transactions to which the
Corporation is a party:

               (i)    a merger or consolidation in which securities possessing
more than fifty percent (50%) of the total combined voting power of the
Corporation's outstanding securities are transferred to a person or persons
different from the persons holding those securities immediately prior to such
transaction, or

               (ii)   the sale, transfer or other disposition of all or
substantially all of the Corporation's assets in complete liquidation or
dissolution of the Corporation.

     12.  Miscellaneous.

as filed with the Secretary of State of Delaware (the "Third Certificate").

                    (b)  The Company and the Initial Investors hereby

duly and validly issued, fully paid and nonassessable, and shall be deemed to be

been issued as part of a single integrated transaction with the issuance of the
Initial Shares.

                         ---------------------------------------------

                    (a)  Prior to the date hereof, the Company has adopted and

Certificate of Incorporation in the form attached hereto as Exhibit A (the
                                                            ---------

Meehan and Scano II, L.P. (each, an "Additional Investor" and, collectively, the
"Additional Investors") agrees, severally but not jointly, to purchase from the
Company at the Closing, and the Company agrees to sell and issue to each
Additional Investor at the Closing, that number of shares of Series C Preferred
Stock set forth opposite such Additional Investor's name on Schedule C hereto

(the "Purchase Shares") for a purchase price of $20.50 per share.

                    1.3  Closing.  The purchase and sale of the Series C
                         -------
Preferred Stock to the Additional Investors and the issuance of the Additional
Stock to the Initial Investors shall take place at the Company's offices located
at 938 Bannock Street, Suite 300, Denver, Colorado 80204 at 10:00 a.m. on June
30, 2000, or at such other time and place as the Company and the Additional
Investors mutually agree upon orally or in writing (which time and place are
designated as the "Closing"). No later than July 13, 2000, the Company shall
deliver to each Additional Investor a certificate representing the Series C
Preferred Stock that such Additional Investor is purchasing against payment of
the purchase price therefor by wire transfer of immediately available funds and
shall deliver to each Initial Investor a certificate representing the Additional
Shares such Initial Investor is entitled to receive.

                    1.4  Post-Closing Obligations.  In the event that, at any
                         ------------------------
time, the Company's representation and warranty in Section 2.2 is determined not
to have been true when made, the Company shall promptly issue to the Additional
Investors, on a pro rata basis as an adjustment to the purchase price paid for
the shares of Series C Preferred Stock purchased hereunder and without the
payment of additional consideration by the Additional Investors, an additional
number of shares of Series C Preferred Stock such that each Additional Investor
would own the same economic interest and voting power as it would have owned had
such representation and warranty been true and correct in all respects when
made. If at the time of an adjustment pursuant to the preceding sentence any
shares of Series C Preferred Stock purchased

                                       2
<PAGE>

hereunder have been converted into Common Stock, the Company shall issue
additional shares of Common Stock with respect to such converted shares of
Series C Preferred Stock based on the conversion ratio that would have been in
effect if such shares had remained outstanding. Any additional shares issued
pursuant to this Section 1.4 shall (i) be treated as if they were issued at the
Closing, (ii) shall reflect any anti-dilution adjustments arising from the date
of Closing through the date of such issuance, and (iii) be deemed to be an
adjustment to the per share purchase price of the Series C Preferred Stock set
forth in Section 1.2(b) above and to have been issued as part of a single
integrated transaction with the issuance of the shares of Series C Preferred
Stock at the Closing. Concurrently with each such issuance, the Company shall
pay or accrue all dividends or other distributions which would have been paid or
accrued with respect to such additional shares from the date of Closing through
the date of such issuance.

                    1.5  Subsequent Sale of Series C Preferred Stock. The
                         -------------------------------------------
Company may sell up to an additional 1,609,800 shares of Series C Preferred
Stock at a price of not less than $20.50 per share (and otherwise on
substantially identical terms) on or prior to August 15, 2000 to one or more
additional purchasers who are "qualified institutional buyers" as defined under
Rule 144A of the Act (as hereinafter defined), selected by the Company and

     Preferred Stock, par value $0.001 (the "Preferred Stock"), of which (i)
     3,310,000 shares have been designated Series A Preferred Stock (the "Series
     A Preferred Stock"), of which 3,309,953 shares are outstanding, (ii)
     7,000,000 shares have been designated Series B Preferred Stock (the "Series
     B Preferred Stock"), of which 6,896,552 shares are outstanding and (iii)
     7,318,000 shares have been designated Series C Preferred Stock (the "Series
     C Preferred Stock"), of which 1,386,364 shares are outstanding. The rights,
     privileges and preferences of the Series A Preferred Stock, Series B
     Preferred Stock, and Series C Preferred Stock are as stated in the Restated
     Certificate.

                              (ii)  Common Stock. 42,372,000 shares of common
                                    ------------
     stock, par value $0.001 ("Common Stock"), of which 3,657,630 shares are
     issued and outstanding.

                         (b)   The outstanding shares of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock and Common Stock are
owned by the stockholders and in the numbers specified in Exhibit B hereto.
                                                          ---------

                         (c)   The outstanding shares of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock and Common Stock are
all duly and validly authorized and issued, fully paid and nonassessable, and
were issued in compliance with all applicable state and federal laws concerning
the issuance of securities.

                         (d)   Except for (A) the conversion privileges of the
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock,
(B) the rights provided in Section 3 of the Fourth Amended and Restated
Stockholders' Agreement in the form attached hereto as Exhibit C (the
                                                       ---------
"Stockholders' Agreement"), and (C) 1,798,000 options outstanding as of June 15,
2000, as set forth on Schedule 2.2 (which list is true and complete in all
                      ------------
material respects), and such other options which have been granted in the
ordinary course by the Company since such date to purchase shares of the
Company's Common Stock pursuant to the Company's 1997 Stock Option Plan, as
amended (the "Option Plan"), which Option Plan authorizes the grant of options
to purchase up to 2,685,000 shares of Common Stock ("Management Option Pool"),
there are no outstanding options, warrants, rights (including conversion or
preemptive rights) or agreements for the purchase or acquisition from the
Company of any shares of its capital stock. All options granted from the
Management Option Pool shall contain vesting and buy-back restrictions in
substantially the same form as issuances of options from the Management Option
Pool prior to the date of this Agreement. The Company also expects to grant
warrants to purchase up to 250,000 shares of Common Stock to a lender or
financial institution in connection with a new credit facility. The Company is
not a party or subject to any agreement or understanding which affects or
relates to the voting or giving of

Company or by a director of the Company.

                         (e)   The 1,386,364 outstanding shares of Series C
Preferred Stock combined with the issuance by the Company of 4,320,953 shares of
Series C Preferred Stock pursuant to the terms of this Agreement, as of the date
hereof would constitute, in the aggregate, approximately 26% of the Company's
outstanding capital stock, calculated on a fully diluted basis.

                    2.3  Subsidiaries. The Company does not presently own or
                         ------------
control, directly or indirectly, any interest in any other corporation,
association, or other business entity, except for the subsidiaries listed on
Exhibit D attached hereto. The Company is not a participant in any joint
---------
venture, partnership, or similar arrangement. The Company is not, directly or
indirectly, subject to any obligation or requirement to provide funds to, or
invest in any company, partnership, association, joint venture or similar non-
corporate business enterprise.

                    2.4  Authorization. All corporate action on the part of the
                         -------------
Company, its officers, directors and stockholders necessary for the
authorization, execution and delivery of this Agreement, the Fourth Amended and
Restated Investors' Rights Agreement in the form attached hereto as Exhibit E
                                                                    ---------

performance of all obligations of the Company hereunder and thereunder, and the
authorization (or, in the case of the Common Stock, reservation for issuance),
sale and issuance of the Series C Preferred Stock has been taken or will be
taken prior to the Closing. This Agreement, the Investors' Rights Agreement, and
the Stockholders' Agreement constitute valid and legally binding obligations of
the Company, enforceable in accordance with their respective terms, except (i)
as limited by applicable bankruptcy, insolvency, reorganization, moratorium and
other laws of general application affecting enforcement of creditors' rights
generally, (ii) as limited by laws relating to the availability of specific
performance, injunctive relief or other equitable remedies, and (iii) to the
extent the indemnification provisions contained in the Investors, Rights
Agreement may be limited by applicable federal or state securities laws.

                    2.5  Valid Issuance of Preferred and Common Stock. The
                         --------------------------------------------
Series C Preferred Stock that is being purchased hereunder, when issued, sold
and delivered in accordance with the terms of this Agreement for the
consideration expressed herein, will be duly and validly issued, fully paid and
nonassessable, free and clear of all liens and other encumbrances and will be
free of restrictions on transfer, other than restrictions on transfer under this
Agreement, the Investors' Rights Agreement, the Stockholders' Agreement and
under applicable state and federal securities laws. The Common Stock issuable

                    2.6  Consents. No consent, approval, order or authorization
                         --------

Agreement which have not been obtained prior to the date of this Agreement,
except for filings required pursuant to applicable federal and state securities
laws and blue sky laws.

                    2.7  Offering. The Company filed a Registration Statement
                         --------
on Form S-1 with the Securities and Exchange Commission on February 18, 2000 and
filed amendments thereto on March 28, 2000 and May 12, 2000 (File No. 333-30684)
for the issuance of up to 8,050,000 shares of its Common Stock. Assuming the
truth and accuracy of each Investor's representations set forth in Section 3 of
this Agreement, including without limitation the qualification of each Investor
as a "qualified institutional buyer" within the meaning of Rule 144A of the
Securities Act of 1933, as amended (the "Act"), or an institutional "accredited
investor" as defined under Regulation D of the Act as set forth in Section 3.10,
the offer, sale and issuance of the Series C Preferred Stock as contemplated by
this Agreement and the issuance of the Common Stock upon conversion of such
Series C Preferred Stock as contemplated by the Restated Certificate are exempt
from the registration requirements of the Act.

                    2.8  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, the
Investors' Rights Agreement or the Stockholders' Agreement or the right of the
Company to enter into any of the foregoing or to consummate the transactions
contemplated hereby or thereby, or that would have, either individually or in
the aggregate, an MAE. 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 that the Company intends to initiate.

                    2.9  Proprietary Information Agreements. Each employee and
                         ----------------------------------
officer of the Company has executed a Proprietary Information and Inventions
Agreement in substantially the form provided to the Investors.

                    2.10 Patents and Trademarks. Schedule 2.10 sets forth a
                         ----------------------  -------------
complete and accurate list and description of all material franchises, licenses,
patents, patent rights, patent applications, trademarks, trademark rights,
trademark applications, service marks, service mark rights, trade names, trade
name rights, copyrights, copyright applications, and rights with respect to any
of the foregoing (collectively, "Intellectual Property") presently owned or held
by the Company. The Company owns the right to use all of the Intellectual
Property. To the actual knowledge of the Company (without independent
investigation), the Intellectual Property is all that is necessary for the
Company to conduct its business as presently conducted or as it is presently
proposed to be conducted. To its knowledge (but without having conducted any
special investigation or patent search), no Intellectual Property conflicts with
or infringes on the valid rights of others and the Company has not received any
notice of infringement upon or

                                       6
<PAGE>

conflict with the asserted rights of others. No event has occurred which
permits, or after notice or lapse of time would permit, the revocation or
termination of any of the Intellectual Property. The Company has a valuable body
of trade secrets, including know-how, concepts, computer programs, technology,
streaming media files, domain name, domain name applications, databases,
websites, other materials included on the Company's website and other technical
data (the "Proprietary Information"). To its knowledge, the Company has the
right to use the Proprietary Information free and clear of any rights, liens,
encumbrances or claims of others, except that the possibility exists that other
persons may have independently developed trade secrets or technical information
similar or identical to those of the Company. The Company is not aware of any
such independent development nor of any misappropriation or infringement of its
Proprietary Information or Intellectual Property. 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 the use of his or her best efforts to promote the interests of
the Company or that would conflict with the Company's business. The Company does
not believe it is or will be necessary to utilize any inventions of any of its
employees (or people it currently intends to hire) or consultants made prior to
their employment by the Company, except for inventions that have been assigned
or licensed to the Company as of the date hereof. The Company has taken
reasonable steps to protect and preserve the security and confidentiality of its
Intellectual Property and Proprietary Information. Immediately following the
Closing, the Company will continue to own or license all Intellectual Property
and Proprietary Information owned or use by it on the same terms and conditions
as immediately prior to the Closing.

                    2.11 Compliance with Other Instruments. The Company is not
                         ---------------------------------
in violation of any provision of its Restated Certificate or Bylaws or any
securities issued by the Company, any indenture, credit agreement, contract,
agreement, instrument or other undertaking ("Contractual Obligations") or any
judgment, order, writ, decree or contract, statute, rule or regulation to which
the Company or its assets or property is subject ("Requirements of Law"), a
violation of which would have an MAE. The execution, delivery and performance of
this Agreement, the Investors' Rights Agreement and the Stockholders' Agreement
and the consummation of the transactions contemplated hereby and thereby will
not result in any such violation, or be in conflict with or constitute, with or
without the passage of time and giving of notice, either (i) a default under the
Restated Certificate, the Bylaws, any Contractual Obligation or Requirement of
Law, or (ii) an event that results in the creation of any lien, charge or
encumbrance upon any assets of the Company or the suspension, revocation,
impairment, forfeiture or nonrenewal of any material permit, license,
authorization or approval applicable to the Company, its business or operations
or any of its assets or properties.

                    2.12 Agreements; Action.
                         ------------------

                         (a) Except for agreements explicitly contemplated
hereby, there are no agreements, understandings or proposed transactions between
the Company and any of its officers, directors, affiliates or any affiliate
thereof.

<PAGE>

                    (b)   Except for this Agreement, the Investors' Rights

complete and accurate of all material Contractual Obligations of the Company in
effect on and as of the Closing. To its knowledge, each such Contractual
Obligation is valid and enforceable by the Company against any other party
thereto in accordance with its terms except to the extent that such enforcement
may be limited by applicable bankruptcy, insolvency, reorganization, moratorium
and other laws of general application affecting enforcement of creditors' rights
generally, and by laws relating to the availability of specific performance,
injunctive relief or other equitable remedies. The Company has performed and is
in compliance with all of the terms of such Contractual Obligations and all
instruments and agreements relating thereto and no default or event of default,
or event or condition which with notice or lapse of time or both would
constitute such a default or event of default, on its part or, to its actual
knowledge, on the part of any other party thereto exists with respect to any
material Contractual Obligation of the Company, except where such
nonperformance, noncompliance, default or event of default is not reasonably
likely to result in an MAE. The Company has no actual knowledge that any such
Contractual Obligation contains any contractual requirement with which there is
a reasonable likelihood the Company will be unable to comply and such failure to
comply would likely result in an MAE or the Company's compliance is reasonably
likely to result in an MAE.

                    (c)   There are no judgments, orders, writs or decrees to
which the Company is a party or by which it is bound that involve obligations
(contingent or otherwise) of, or payments to the Company, in excess of $25,000.

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

series of its capital stock, (ii) except for the anticipated credit facility
currently being negotiated, as set forth on the Financial Statements (as
hereinafter defined), or pursuant to the Contractual Obligations set forth on
Schedule 2.12, incurred any indebtedness for money borrowed or any other
-------------
liabilities which would be commitments required to be disclosed in the footnotes
to financial statements under generally accepted accounting principles,
individually for which it currently owes, or in the future will owe in excess of
$100,000 or, in the case of indebtedness and/or liabilities individually less
than $100,000, in excess of $250,000 in the aggregate, (iii) made any loans or
advances to any Person, other than advances in the ordinary course of business,
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.

                    (e)   For the purposes of subsections (c) and (d) above, all
indebtedness, liabilities, agreements, understandings, instruments, contracts
and proposed transactions involving the same Person (including Persons 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.

                    (f)   The Company delivered copies of the following customer
contracts between the Company and the named customer (the "Customer Contracts")
to O'Sullivan, Graev & Karabell, LLP, special counsel to Spire (as hereinafter
defined), prior to the date of this Agreement: (i) VERIO Rocky Mountain, Inc.

1999; (iv) Savvis dated February 10, 2000; and (v) the form Data Network
Exchange Facility Services Agreement. The Customer Contracts are materially
similar to all of the Company's other contracts with customers with respect to
terms and conditions but may vary with respect to term, price and services
rendered.

                    2.13 Related-Party Transactions. No employee, officer or
                         --------------------------
director of the Company, holder of greater than five percent (5%) of the
Company's outstanding Common Stock, or member of his or her immediate family is
indebted to, or a party to any agreements, contracts or transactions with the
Company, nor is the Company indebted (or committed to make loans or extend or
guarantee credit) to any of them. To the best of the Company's knowledge, none
of such persons has 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 that competes with the
Company, except that employees, officers or directors of the Company and members
of their immediate families may own stock in publicly traded companies that may
compete with the Company. No member of the immediate family of any officer or
director of the Company is directly or indirectly interested in any material
Contractual Obligation with the Company.

                    2.14 Financial Statements. The Company has delivered to each
                         --------------------
Investor its audited financial statements (balance sheet and statement of
operations, statement of stockholders' equity and statement of cash flows,
including notes thereto) at December 31, 1999 and for the fiscal year then ended
and its unaudited financial statements (balance sheet and statement of
operations, statement of stockholders' equity and statement of cash flows) at

books and records of the Company, have been prepared in accordance with
generally accepted accounting principles applied on a consistent basis
throughout the periods indicated and with each other and fairly present in all
material respects the assets, liabilities, financial condition and operating
results of the Company as of the dates, and for the periods, indicated therein,
subject in the case of unaudited Financial Statements to normal year-end audit
adjustments. Except as set forth in the Financial Statements, the Company has no
liabilities or obligations, contingent or otherwise, other than (i) liabilities
incurred in the ordinary course of business subsequent to March 31, 2000 and
(ii) obligations under contracts and commitments incurred in the ordinary course
of business and not required under generally accepted accounting principles to
be reflected in the Financial Statements, which, in both cases, individually or
in the aggregate, are not material to the financial condition or operating
results of the Company and which the Company has satisfied as they have become
due. Except as disclosed in the Financial Statements, the Company is not a
guarantor or indemnitor of any indebtedness of any other Person. The Company
maintains and will continue to maintain a standard system of accounting
established and administered in accordance with generally accepted accounting
principles.

enter into this Agreement, the Investors' Rights Agreement and the Stockholders'
Agreement, and each such agreement constitutes its valid and legally binding
obligation, enforceable in accordance with its terms, except (i) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium and other laws of
general application affecting enforcement of

                                       14
<PAGE>

creditors' rights generally, (ii) as limited by laws relating to the

securities laws.

          3.2  Purchase Entirely for Own Account. This Agreement is made with
               ---------------------------------
such Investor in reliance upon such Investor's representation to the Company,

confirms, that the Series C Preferred Stock to be received by such Investor and
the Common Stock issuable upon conversion thereof (collectively, the

and not with a view to the resale or distribution of any part thereof in
violation of applicable securities laws, and that such Investor has no present
intention of selling, granting any participation in or otherwise distributing
the same in violation of applicable securities laws. By executing this
Agreement, such Investor further represents that such Investor does not have any
contract, undertaking, agreement or arrangement with any person to sell,
transfer or grant participations to such person or to any third person in
violation of applicable securities laws, with respect to any of the Securities.

          3.3  Disclosure of Information. Such Investor represents that it has

               ---------------------
securities of companies in the development stage and acknowledges that it can
bear the economic risk of its investment, and has such knowledge and experience
in financial or business matters that it is capable of evaluating the merits and
risks of the investment in the Series C Preferred Stock. If other than an
individual, such Investor also represents it has not been organized for the
purpose of acquiring the Series C Preferred Stock.

          3.5  Restricted Securities.  Such Investor understands that the
               ---------------------
Securities it is purchasing are characterized as "restricted securities" under
the federal securities laws inasmuch as they are being acquired from the Company
in a transaction not involving a public offering and that under such laws and
applicable regulations such Securities may be resold without registration under
the Act only in certain limited circumstances. In the absence of an effective
registration statement covering the Series C Preferred Stock (or the Common
Stock issued on conversion thereof) or an available exemption from registration
under the Act, the Series C Preferred Stock (and any Common Stock issued on
conversion thereof) must be held indefinitely. In this connection, such Investor
represents that it is familiar with SEC Rule 144, as presently in effect, and
understands the resale limitations imposed thereby and by the Act, including
without limitation the Rule 144 condition that current information about the
Company be available to the public. Such information is not now available and
the Company has no present plans to make such information available.

accordance with such registration statement; or

                    (ii) (A) Such Investor shall have notified the Company of
the proposed disposition and shall have furnished the Company, if reasonably
requested, with a detailed statement of the circumstances surrounding the
proposed disposition, and (B) if reasonably requested by the Company, such
Investor shall have furnished the Company with an opinion of counsel, reasonably
satisfactory to the Company that such disposition will not require registration
of such shares under the Act. It is agreed that the Company will not require
opinions of counsel for transactions made pursuant to Rule 144 except in unusual
circumstances.

               (b)  Notwithstanding the provisions of subsections (i) and (ii)
above, no such registration statement or opinion of counsel shall be necessary
for a transfer by an Investor to any affiliate or limited or general partner of
such Investor if the transferee agrees in writing to be subject to the terms
hereof to the same extent as if he or she were an original Investor hereunder.

          The Company agrees, upon the request of any Investor or its
transferee, to remove the legend required by paragraph (a) above at such time as
all Securities held by such person may be freely transferred pursuant to SEC
Rule 144(k) or are properly sold pursuant to an effective registration statement
under the Act, and to remove the legend required by paragraph (b) above at such
time as the restrictions of the Investors' Rights Agreement and the
Stockholders' Agreement are no longer applicable to such Securities.

          3.8  Tax Advisors. Such Investor has reviewed with such Investor's
