"Purchaser").

                                    RECITALS

     WHEREAS, the Company has authorized the sale and issuance of an aggregate

     WHEREAS, Purchasers desire to purchase the Shares on the terms and

     WHEREAS, the Company desires to issue and sell the Shares to Purchasers on
the terms and conditions set forth herein;

     NOW, THEREFORE, in consideration of the foregoing recitals and the mutual
promises hereinafter set forth, the parties hereto agree as follows:

     1. AGREEMENT TO SELL AND PURCHASE.

         1.1 AUTHORIZATION OF SHARES. On or prior to the Closing (as defined in
Section 2 below), the Company shall have authorized (a) the sale and issuance to
Purchasers of the Shares and (b) the issuance of such shares of Common Stock to

Company, in the form attached hereto as Exhibit B (the "Restated Certificate").

         1.2 SALE AND PURCHASE. Subject to the terms and conditions hereof, at

<PAGE>   6


Godward LLP, 2595 Canyon Boulevard, Suite 250, Boulder, Colorado 80302 or at
such other time or place as the Company and Purchasers may mutually agree. The
closing(s) of the sale and purchase of the Shares as set forth in Section 2.3
below shall take place at such time and place as the Company and Purchasers
participating therein shall mutually agree at any time until May 1, 1999 (a
"Subsequent Closing") (the First Closing and any Subsequent Closing shall
collectively be referred to herein as a "Closing" and each such date is referred
to as a "Closing Date").

         2.2 DELIVERY. At each Closing, subject to the terms and conditions
hereof, the Company will deliver to the Purchasers certificates representing the
number of Shares to be purchased at such Closing by each Purchaser, against
payment of the purchase price therefor, by certified check or wire transfer made
payable to the order of the Company, or by cancellation of indebtedness.

         2.3 SUBSEQUENT CLOSINGS. The Company may sell any or all of the Shares
remaining after the initial closing hereunder to such purchasers as may be
approved by the Board of Directors of the Company (the "Subsequent Purchasers").
Any subsequent sales of Shares pursuant to the foregoing provision shall be made
pursuant to the provisions of this Agreement, including, without limitation, the
representations and warranties by such Purchasers as set forth in Section 4. Any
shares of Series A Preferred Stock sold pursuant to this Section 2.3 shall be
deemed "Shares" for all purposes under this Agreement, and each such Subsequent
Purchaser shall be deemed to be a "Purchaser" hereunder, and an "Investor" under
the Investor Rights Agreement.

     3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

     Except as set forth on a Schedule of Exceptions delivered by the Company to
the Purchasers at the First Closing, the Company hereby represents and warrants
to each Purchaser as of the date of this Agreement 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 and the Investor Rights Agreement in the form attached hereto as
Exhibit C (the "Investor Rights Agreement"), to issue and sell the Shares and
the Conversion Shares, and to carry out the provisions of this Agreement, the
Investor Rights Agreement 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 all 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.

         3.2 SUBSIDIARIES. The Company does not own or control any equity
security or other interest of any other corporation, limited partnership or
other business entity. The Company is not a participant in any joint venture,

         3.3 CAPITALIZATION; VOTING RIGHTS. The authorized capital stock of the
Company, immediately prior to the Closing, will consist of twenty million
(20,000,000) shares of Common Stock, (par value $.001) per share, two million
thirty three thousand three hundred ninety (2,033,390) shares of which are
issued and outstanding and one million seven hundred fifty thousand (1,750,000)
shares of which are reserved for future issuance to employees, officers,
directors and consultants pursuant to the Company's 1999 Equity Incentive Plan
and eight million five hundred thousand (8,500,000) shares of Preferred Stock,
(par value $.001) per share, all of which are designated Series A Preferred
Stock, none of which are issued and outstanding. All issued and outstanding
shares of the Company's Common Stock (a) have been duly authorized and validly
issued, (b) are fully paid and nonassessable, and (c) 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. Each series of Preferred Stock is
convertible into Common Stock on a one-for-one basis. The Conversion Shares have
been duly and validly reserved for issuance. Other than the 1,750,000 shares
reserved for issuance under the Company's 1999 Equity Incentive Plan, the option
to purchase up to four hundred thirty eight thousand five hundred ninety six

to that certain Key Employee Agreement by and between the Company and Kevin
Randolph dated on or about the date hereof, and the proposed issuance of up to
one million two hundred fifty thousand (1,250,000) shares of Series A Preferred
Stock to certain shareholders of Asia Communications Global Limited ("ACGL")
pursuant to that certain Asset Purchase Agreement by and between the Company and
ACG, Inc., a subsidiary of ACGL, dated on or about the date hereof (the "ACGL
Agreement"), and except as may be granted pursuant to this Agreement and the
Investor Rights Agreement, 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.

         3.4 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 Investor Rights Agreement, 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

binding obligations of the Company enforceable in accordance with their terms,
except (a) as limited by applicable bankruptcy, insolvency, reorganization,
moratorium or other laws of general application affecting enforcement of
creditors' rights, (b) general principles of equity that restrict the
availability of equitable remedies, and (c) 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

not be subject to any preemptive rights or rights of first refusal that have not
been properly waived or complied with.

         3.5 LIABILITIES. The Company has no material liabilities and, to the
best of its knowledge, knows of no material contingent liabilities not otherwise
disclosed in writing to the Purchasers, except current liabilities incurred in
the ordinary course of business 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 (other than obligations of, or payments to, the
Company arising from purchase or sale agreements entered into in the ordinary
course of business), or (ii) the transfer or 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 the development, manufacture or
distribution of the Company's products or services, or (iv) indemnification by
the Company with respect to infringements of proprietary rights (other than
indemnification obligations arising from purchase or sale or license agreements

               (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 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 $100,000 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.

         3.7 TITLE TO PROPERTIES AND ASSETS; LIENS, ETC. The Company has good
and marketable title to its properties and assets, and good title to its
leasehold estates, in each case subject to no mortgage, pledge, lien, lease,
encumbrance or charge, other than (a) those resulting


                                       4.
<PAGE>   9


from taxes which have not yet become delinquent, (b) 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 (c)
those that have otherwise arisen in the ordinary course of business. The Company
is in compliance with all material terms of each lease to which it is a party or
is otherwise bound.

         3.8 PATENTS AND TRADEMARKS. To the best of its knowledge, the Company
owns or possesses sufficient legal rights to all patents, trademarks, service
marks, trade names, copyrights, trade secrets, licenses, information and other
proprietary rights and processes necessary for its business as now conducted and
as presently 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
presently 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 presently
proposed to be conducted. Neither the execution nor delivery of this Agreement
or the Investor Rights 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
presently 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.

         3.9 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. The execution, delivery, and performance of and compliance
with this Agreement, and the Investor Rights Agreement, and the issuance and
sale of the Shares pursuant hereto and of the Conversion Shares pursuant to the
Restated Certificate, 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.


                                       5.

         3.10 LITIGATION. There is no action, suit, proceeding or investigation
pending or to the Company's knowledge currently threatened in writing against
the Company that questions the validity of this Agreement, or the Investor
Rights Agreement 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 any of the
foregoing. The foregoing includes, without limitation, actions pending or
threatened in writing (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.

         3.11 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 (a) that any of its returns,
federal, state or other, have been or are being audited as of the date hereof,
or (b) 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.

         3.12 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 other than the Company's Form of Proprietary Information and
Inventions Agreement. Other than the Company's 1999 Equity Incentive Plan and
the Key Employment Agreements for Kevin Randolph and Ed Roberto, 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


                                       6.
<PAGE>   11


employees, intends to terminate his, her or their employment 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.

         3.13 PROPRIETARY INFORMATION AND INVENTIONS AGREEMENTS. Each current
employee, officer and consultant of the Company has executed a form of
Proprietary Information and Inventions Agreement.

         3.14 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.

         3.15 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,

without undue burden or expense, any similar authority for the conduct of its
business as planned to be conducted.

         3.16 ENVIRONMENTAL AND SAFETY LAWS. To its knowledge, the Company is

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 or any state securities
laws.

     4. REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS.

         Each Purchaser hereby represents and warrants to the Company 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 Investor Rights Agreement and to carry out their provisions.
All action on Purchaser's part required for the lawful execution and delivery of
this Agreement and the Investor Rights Agreement have been or will be
effectively taken prior to the Closing. Upon their execution and delivery, this
Agreement and the Investor Rights Agreement will be valid and binding
obligations of Purchaser, enforceable in accordance with their terms, except (a)
as limited by applicable bankruptcy, insolvency, reorganization, moratorium or
other laws of general application affecting enforcement of creditors' rights,
(b) general principles of equity that restrict the availability of equitable
remedies, and (c) 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 neither the
Shares nor the Conversion Shares have 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 Investor Rights Agreement.
Further, Purchaser is aware of no publication of any advertisement in connection
with the transactions contemplated in the Agreement.


                                       8.
<PAGE>   13


               (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 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 as in effect from
time to time, 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 following the required holding period under Rule
144 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.

     5. CONDITIONS TO CLOSING.

         5.1 CONDITIONS TO PURCHASERS' OBLIGATIONS AT THE CLOSING. Purchasers'
