                                MERGER AGREEMENT
                                ----------------

                               December 14, 1999
                               -----------------


                  The parties to this agreement are Network Event Theater,
Inc., a Delaware corporation ("NET"); Sixdegrees Acquisition Corp., a Delaware
corporation and a wholly-owned subsidiary of NET ("Newco"); and sixdegrees,
inc., a Delaware corporation (the "Company").

                  The Company is engaged in the business of developing a
network database service, accessible from the Company's website, that enables
members of the Company's service to establish connections with other members
through their respective familial, professional and personal relationships (the
"Business"). The parties wish to provide for the acquisition of the Company by
NET through a tax-free reorganization by means of the merger of Newco into the
Company and the conversion of the Company's outstanding shares into common
stock and Convertible Preferred Stock of NET. Following the merger, the
Business will continue to be operated by the Company, as the surviving
corporation of the merger, and the Company will be a wholly-owned subsidiary of
NET.

                  It is agreed as follows:

                  1.       Merger; Provisions Relating to Surviving Corporation.

                           1.1 Certificate of Merger. Contemporaneously with
the closing under this agreement, a duly executed certificate of merger
providing for the merger (the "Merger") of Newco into the Company shall be
delivered for filing to the Secretary of State of Delaware. The Merger shall
become effective upon the filing of the certificate of merger in Delaware (the
"Effective Time").

                           1.2 Merger. At the Effective Time, Newco shall be
merged into the Company pursuant to the Delaware General Corporation Law and
the separate existence of Newco shall cease. The Company shall be the surviving
corporation of the Merger and shall continue to be governed by the Delaware
General Corporation Law.

                           1.3 Certificate of Incorporation and By-Laws of the
Company. The certificate of incorporation and by-laws of Newco in effect at the
Effective Time shall become the Company's certificate of incorporation and
by-laws, and shall continue as such until amended.

                           1.4 Certificate of Designation of NET. NET shall
adopt and file with the Secretary of State of Delaware, on or before the
Effective Time, a certificate of designation (the "Certificate of Designation")
in the form of exhibit 1.4, which sets forth a description and

<PAGE>

designation of a new class of NET's Convertible Preferred Stock (the
"Convertible Preferred Stock").

                           1.5 Directors and Officers. Commencing at the
Effective Time, the persons then serving as the directors and officers of Newco
shall be the directors and officers of the Company and shall hold office for
the term provided in the Company's bylaws after the Merger.

                           1.6 Closing. The closing under this agreement shall
take place at the offices of Proskauer Rose LLP, 1585 Broadway, New York, New
York 10036 (or at such other place as the parties may agree upon in writing) on
the third business day following the satisfaction of the conditions set forth
in sections 6.1 and 6.2 and immediately prior to the filing referred to in
section 1.1, but in any event no later than January 31, 2000. The date on which
the closing is held is referred to in this agreement as the "Closing Date." At
the closing, the parties shall execute and deliver the documents referred to in
section 7.

                  2.       Conversion of Shares Upon the Merger.

                           2.1      Conversion of Shares.

                                    (a) All of the Company's shares of common
stock and all of the Company's shares of Preferred Stock (including all accrued
dividends thereon) that are issued and outstanding at the Effective Time shall
then automatically cease to be outstanding and shall be converted into (x) an
aggregate number of shares of NET common stock equal to 3,400,000 less the
number of shares of NET common stock issuable upon the exercise of all options
and warrants to purchase shares of NET common stock to be issued upon the
Merger pursuant to sections 2.1(d) and (e), and (y) an aggregate number of
shares of Convertible Preferred Stock equal to (i) 766,667, plus (ii) a number
calculated by dividing the aggregate exercise price of all Company options and
warrants by $24 (which shares are convertible into an equal number of shares of
NET common stock, as provided in the Certificate of Designation) (collectively,
the "Merger Consideration"), plus (z) any additional shares of NET common stock
issuable pursuant to section 2.1(f).

                                    (b) The number of shares of NET common
stock and NET preferred stock distributable to each Company stockholder under
sections 2.1(a)(x), 2.1(a)(y) and 2.1(a)(z) and upon distribution from escrow
pursuant to section 2.2(a) shall in each case be that portion of the amount
distributed determined by multiplying the total amount being distributed by a
fraction of which the numerator shall be the number of shares of Company common
stock such stockholder owns, or in the case of the Convertible Preferred Stock
is entitled to receive upon conversion (plus the number of shares of Company
common stock distributable as a dividend as contemplated by section
5.2(i)(iv)), and the denominator shall be the aggregate number of shares of the
Company's common stock the holders of the Company's common and preferred stock
own or are entitled to receive upon conversion of their preferred stock (plus
any dividend shares). Any fractional shares shall be paid in cash based on a
value of $24 per share. After the Effective Time, the holder of any shares of
common stock or preferred stock of the


<PAGE>

Company that were outstanding prior to the Effective Time shall have no rights
with respect to those shares except to receive the stock of NET into which
those shares have been converted in accordance with the terms of this
agreement.

                                    (c) All of Newco's shares that are issued
and outstanding at the Effective Time shall then automatically be converted
into 100 duly authorized, validly issued, fully paid and non-assessable shares
of common stock of the Company.

                                    (d) At the Effective Time, each option to
purchase shares of common stock of the Company issued to employees of the
Company ("Employee Options") that was outstanding at the Effective Time shall,
for each share of common stock which could be purchased upon exercise,
automatically be converted into an option to purchase .083 shares of NET common
stock, on the same terms and conditions and with the same vesting provisions as
the option to purchase shares in the Company held by such holder at the
Effective Time. These options will be issued pursuant to newly adopted stock
option plans of NET on the same terms and conditions as the existing Company
stock option plans (the "New NET Stock Option Plans"). On consummation of the
merger of NET with Common Places LLC referred to in section 5.6(c), the options
outstanding under the New NET Stock Option Plans will be converted into
comparable options outstanding under the YouthStream Media Networks Inc.
("YouthStream") Stock Incentive Plan, a copy of which has been delivered to the
Company.

                                    (e) At the Effective Time, each option
(other than the Employee Options) and each warrant to purchase shares of common
stock of the Company that was outstanding at the Effective Time shall
automatically be converted into an option or warrant to purchase .083 shares of
NET common stock, on the same terms and conditions as the option or warrant to
purchase shares in the Company held by such holder at the Effective Time. There
are no options or warrants to purchase shares of preferred stock of the Company
outstanding.

                                    (f) If prior to the Effective Time there is
a stock split or stock combination or other recapitalization of NET, the number
of shares of NET common stock and NET Convertible Preferred Stock distributable
hereunder shall be appropriately adjusted to reflect such split, combination or
recapitalization.

                                    (g) Notwithstanding anything in this
agreement to the contrary, any shares of common stock or preferred stock of the
Company that are issued and outstanding immediately prior to the Effective Time
and which are held by stockholders who have not voted such shares in favor of
the Merger (or consented thereto in writing), who shall have delivered a
written objection to the Merger and a demand for appraisal of such shares in
accordance with Section 262 of the Delaware General Corporation Law (the
"DGCL") and who shall not have failed to perfect or shall not have effectively
withdrawn or lost their rights to appraisal and payment under the DGCL (the
"Dissenting Shares"), shall not be converted into the right to receive a
portion of the Merger Consideration, but shall instead entitle the holder
thereof to receive that consideration determined pursuant to section 262 of the
DGCL; provided, however, that if such holder shall have failed to perfect or
shall have effectively withdrawn such holder's right to appraisal and payment
under the DGCL, such holder's shares shall thereupon be deemed


                                       3
<PAGE>


to have been converted, at the Effective Time, into the right to receive a
portion of the Merger Consideration, without any interest thereon. The
aggregate number of shares of NET Convertible Preferred Stock and common stock
issuable upon the Merger shall be reduced by the aggregate number of shares of
each class that the stockholders of the Company who validly perfected (and did
not withdraw) their dissenters' rights would but for their exercise of their
appraisal rights have been entitled to receive upon the Merger.

                                    (h) The Company shall give NET prompt
notice of any demands for appraisal pursuant to the applicable provision of the
DGCL received by the Company, any withdrawals of such demands, and any other
instruments served pursuant to the DGCL and received by the Company and the
opportunity to participate in all negotiations and proceedings with respect to
demands for appraisal under the DGCL. The Company shall not, except with prior
written consent of NET, make any payment with respect to any such demands for
appraisal or offer to settle or settle any such demands.

                                    (i) Within 15 days after the end of each
calendar year 2000-2002, NET shall issue to the stockholders of the Company, as
additional Merger Consideration, an aggregate number of shares of NET common
stock equal to (1) the excess of the value (at $24.00 per share) of all shares
of NET common stock issuable upon exercise of any options and warrants issued
pursuant to the Merger in exchange for options or warrants to purchase shares
of the Company's common stock or Preferred Stock that expired unexercised
during the prior calendar year over the aggregate exercise price of such
unexercised options or warrants, divided by (2) $24.00, adjusted to reflect any
split, combination or recapitalization of NET after the date hereof. Any
fractional shares shall be paid in cash based on a value of $24 per share.

                  2.2      Payment of Merger Consideration.

                                    (a) Promptly after the Effective Time, (1)
NET shall issue to an escrow agent to be designated by NET, which shall be a
commercial bank of national reputation that shall have executed and delivered
an escrow agreement in substantially the form of exhibit 2.2 (the "Escrow
Agreement"), 75,000 shares of the NET common stock distributable under section
2.1(a)(x) and all of the shares of Convertible Preferred Stock to which the
former stockholders of the Company are entitled, such shares to be held for one
year after the Effective Time as security for the indemnification obligations
of the Company pursuant to section 8, and (2) NET shall issue to the former
holders of Company common stock or Company preferred stock the remaining shares
of NET common stock distributable under section 2.1(a)(x), plus in each case
any applicable shares distributable pursuant to section 2.1(a)(z). At any time
after the Effective Time, each former holder of Company common stock or Company
preferred stock may surrender to NET the certificate or certificates for that
holder's shares and shall receive in exchange the shares of common stock of NET
and Convertible Preferred Stock to which such holder is entitled by virtue of
the Merger (other than the shares delivered and held pursuant to the Escrow
Agreement). The Escrow Agent's fee shall be paid by NET.

                                    (b) At the closing provided for in section
1.6, the Company shall deliver to NET a list, certified as true and complete by
the Company's chief financial officer,


                                       4
<PAGE>

setting forth the names and addresses of all of the record holders of the
Company's common stock and preferred stock and all record holders of the
Company's options and warrants to purchase common stock and Convertible
Preferred Stock, if any, and the number of shares of common stock of NET and
Convertible Preferred Stock that each stockholder of record is entitled to
receive on the Merger (which shall aggregate to the Merger Consideration) and
the number of shares of NET common stock each option or warrant holder of
record is entitled to receive upon exercise of the option or warrant. In making
any payments to the former holders of the Company's common stock or preferred
stock, NET shall be entitled to rely on that list and shall not have any
liability of any kind arising out of any payment made in accordance with the
list or the failure to make any payment to any holder whose name and holdings
of common stock or preferred stock or options or warrants is omitted from, or
is not accurately stated on, that list.

                  3. Representations and Warranties by the Company. The Company

delivery and performance of this agreement by each of Newco and NET will not
(a) conflict with Newco's or NET's certificate of incorporation or by-laws and

                           5.3 Consents and Approvals. The Company shall use
its best efforts to obtain, at the earliest practicable date, in form and
substance reasonably satisfactory to NET, all consents and approvals required
for the consummation of the transactions contemplated by this agreement,
without any condition adverse to NET or the operation of the Company after the
Effective Time. NET shall cooperate with the Company in obtaining the consents.

                           5.4 Interim Financial Statements. The Company shall
promptly deliver to NET copies of any monthly or quarterly financial statements
or other reports of the Company that may be prepared by the Company during the
period from the date of this agreement to the Closing Date. All such financial
statements shall be prepared from the books and records of the Company, shall
show all income and expenses attributable to the Company and shall fairly
present in all material respects the financial position and results of
operations of the Company as of and for the periods indicated (subject, in the
case of interim financial statements, to normal year-end audit adjustments).
The Company shall also furnish to NET any other information concerning the
financial and operating condition of the Company as NET from time to time
reasonably may request.

                           5.5 Other Action. No party to this agreement shall
take any action that would result in any of its or their representations and
warranties not being true as of the Closing Date. Each of the parties to this
agreement shall use its best efforts to cause the fulfillment at the earliest
practicable date of all of the conditions to the obligations of the parties to
consummate the transactions contemplated by this agreement.

                           5.6      Securities Act Matters.

                                    (a) The Company recognizes that the
issuance of shares of NET common stock and Convertible Preferred Stock under
section 2 is intended to be exempt from registration under the Securities Act
of 1933, as amended (the "Securities Act"), by virtue of section 4(2) of the
Securities Act. In that connection, the Company acknowledges that sales or
transfers of shares of NET common stock and Convertible Preferred Stock to be
acquired by the stockholders of the Company are restricted by the Securities
Act and by certain state securities laws and that a legend referring to that
restriction and the restrictions pursuant to this agreement will be placed on
the certificates representing the shares.

                                    (b) None of the stockholders of the Company
may sell or otherwise transfer the shares acquired by them pursuant to this
agreement unless the transaction is registered under the Securities Act and
applicable state securities laws or an exemption from registration is
available.

                                    (c) NET intends to file a Registration
Statement on Form S-4 (the "S-4") in connection with its proposed merger with
Common Places, LLC (the "Common Places Merger"). All of the outstanding shares
of NET at the time of the filing of the S-4, including all shares of common
stock to be issued under this agreement and the shares of common stock of NET
issuable upon conversion of the shares of Convertible Preferred Stock to be
issued under this agreement, shall be exchanged for shares of YouthStream, as
successor to


                                      18
<PAGE>

NET, and shall thereafter be freely tradeable. If the S-4 does not
become effective by April 30, 2000, the Company shall promptly thereafter file
a Registration Statement on Form S-3 registering the resale of the shares of
common stock of NET issued to the Company stockholders in the Merger (the "Form
S-3"), including the shares of common stock issuable upon conversion of the
Convertible Preferred Stock (any resale to be limited by the terms of the
Lock-Up Agreements referred to in section 5.8). The Company shall use
reasonable efforts to cause the Form S-3 to become effective as promptly as
practicable after the filing and to keep the S-3 effective until June 30, 2001.
If the S-4 does not become effective and if for any reason the Form S-3 is not
then effective and within two years after the Effective Time NET proposes to
file a registration statement (other than a registration statement on Form S-4
or S-8 or any form substituting therefor or the equivalent thereof) on which
securities of NET are to be registered for sale by NET, NET shall give written
notice of such proposed filing to each of the stockholders of the Company at
least 30 days before the anticipated filing date of such registration statement
and such notice shall offer each of the stockholders the opportunity to have up
to 10% of the shares of NET common stock issued to him on the Closing Date
(including the shares issuable upon conversion of the Convertible Preferred
Stock) included in the registration statement. Each stockholder of the Company
desiring to have any of his shares of NET common stock included in the
registration statement shall so advise NET in writing within 20 days after the
date such notice is given by NET (which request shall set forth the number of
shares of NET common stock for which registration is requested). NET shall
include in the registration statement all such securities requested to be
included therein unless, if the registration statement is filed pursuant to an
underwritten offering, the managing underwriter delivers a written opinion that
the inclusion of such requested securities would likely have an adverse effect
on the offering, in which event NET shall include only so many shares as the
managing underwriter indicates may be included without having an adverse effect
on the offering.

                  Notwithstanding the foregoing, NET shall not have any
obligation to include any of a stockholder's shares in a registration statement
other than the S-3 if, in the opinion of NET's counsel (a copy of which shall
be addressed and delivered to the stockholder), the stockholder is then
permitted by law to sell, in a single transaction pursuant to the provisions of
Rule 144 under the Securities Act, all of the shares of common stock of NET
then held by him. NET shall not have any obligation to notify any of the
stockholders of the filing of a registration statement if he has received a
copy of the opinion referred to in the preceding sentence.

                  Each stockholder of the Company shall furnish to NET such
information and other material as NET or its counsel may reasonably request
with respect to the public offering of the shares of common stock of NET and
the stockholder shall take any other action which NET may reasonably request in
connection with the registration statement.

                                    (d) NET shall deliver to the Company, no
later than 10 days after the date of this agreement, disclosure materials to be
delivered by the Company to its stockholders in connection with their vote on
the Merger.

                           5.7 Stockholder Approval. NET shall use reasonable
efforts to obtain approval of its stockholders of the YouthStream Stock
Incentive Plan at the meeting at which the


                                      19
<PAGE>

merger with Common Places LLC is approved by the stockholders of NET. If the
merger with Common Places LLC is not approved by the stockholders of NET by
April 30, 2000, NET shall call a meeting of its stockholders in accordance with
law as promptly as practicable thereafter to approve the issuance to the
stockholders of the Company of the common stock of NET issuable upon conversion
of the Convertible Preferred Stock and to approve the New NET Stock Option
Plans and shall use best efforts to obtain the requisite vote of approval. If
the stockholders of NET do not approve the New NET Stock Option Plans or the
YouthStream Stock Incentive Plan within one year after adoption by the board of
directors of NET, NET shall indemnify and hold harmless any holder who
exercises an option from any tax consequences of exercise and sale of the
underlying shares of NET common stock that are more adverse than those tax
consequences had the NET Stock Option Plans been so approved by the
stockholders of NET (and NET shall lend to any option holder, without interest,
an amount equal to the taxes payable upon exercise of such options, to be
repaid upon sale of the underlying shares). Upon such stockholder approval, the
Convertible Preferred Stock shall immediately convert into common stock of NET
in accordance with the terms of the Convertible Preferred Stock.

                           5.8 Lock-Up Agreements. The Company shall use
reasonable efforts to cause stockholders of the Company holding at least 95% of
the sum of the Company's common stock and the Company's common stock issuable
upon conversion of the Company's Convertible Preferred Stock to enter into
Lock-Up Agreements (the "Lock-Up Agreements") with NET in substantially the
form of exhibit 5.8, prohibiting each stockholder from selling 90% of the
shares of common stock of NET issuable to him pursuant to this agreement
(including the shares of common stock of NET issuable upon conversion of the
Convertible Preferred Stock) and 90% of any shares of common stock issuable to
him upon exercise of any option or warrants for a period of nine months after
the Effective Time and 80% of those shares for a period of one year after the
Effective Time. For purposes of each Lock-Up Agreement, shares issued to the
Escrow Agent which would otherwise have been issued to any holder shall be
deemed shares owned by that holder.

                           5.9 Non-Competition Agreements. The Company shall
use reasonable efforts to cause the management and other key employees of the
Company listed on schedule 5.9 to enter into Non-Competition Agreements in
substantially the form of exhibit 5.9.

                           5.10 Voting Agreement. Each of the stockholders of
the Company listed on schedule 5.10 has entered into a Voting Agreement with
NET, substantially in the form of exhibit 5.10, agreeing to vote all of the
shares of the Company owned by that stockholder in favor of the Merger and the
transactions contemplated by the agreement.

                           5.11 S-8. NET shall cause the options to be issued
to employees of the Company pursuant to the New NET Stock Option Plans or the
YouthStream Stock Option Plan to be included in the Registration Statement on
Form S-8 filed by NET with respect to its existing stock option plans or in the
Registration Statement on Form S-8 to be filed by YouthStream with respect to
its stock option plans after the merger with Common Places LLC.

                           5.12 D&O Insurance. NET shall cause the Company to
maintain its existing directors and officers liability insurance for a period
of one year after the Effective Time. After the Merger, NET shall not amend the
certificate of incorporation of Newco to limit or eliminate the indemnification
of officers and directors as currently provided for in article ___ of Newco's
certificate of incorporation.

                           5.13 Company Stockholder Approval. The Company shall
call a meeting of its stockholders in accordance with law as promptly as
practicable and, in any event, no later than 25 days after the date of this
agreement, to approve the Merger and related matters and shall, through its
board of directors, use reasonable efforts to solicit the requisite vote of
approval. The board of directors of the Company shall recommend to the
stockholders of the Company that they approve the Merger.

                           5.14 Tax Free Reorganization. The Merger is a tax
free reorganization pursuant to the Internal Revenue Code, and the parties
shall so characterize the Merger and the transactions contemplated by this
agreement for tax and all other purposes.

                           5.15 Common Places Merger. NET shall use reasonable
efforts to cause the merger with Common Places LLC to be effected as promptly
as practicable after the Effective Time; provided, however (a) the board of
directors of NET may make any determination to delay or not to consummate the
merger with Common Places LLC that the board of directors of NET determines to
be in the best interests of the stockholders of NET, and (b) NET shall have no
liability to the Company or its stockholders as a result of any delay or
abandonment of the merger with Common Places LLC as a result of any
determination by the board of directors of NET pursuant to clause (a) above.

                           5.16 Securities Act Covenants. NET shall promptly
deliver to the Representatives copies of all filings with the SEC, including
the S-4, in connection with the Common Places Merger, and all correspondences
to and from the SEC with respect to that Merger. NET shall file all reports
required under the Securities Exchange Act of 1934 on a timely basis to permit
sales of shares of NET common stock by the Company's stockholders pursuant to
Rule 144 under the Securities Act of 1933.

                           5.17 Accountants Consent. The Company shall use
reasonable efforts to cause PricewaterhouseCoopers LLP to deliver to NET its
consent to the inclusion of the audited financial statements of the Company for
the years ended December 31, 1997, 1998 and 1999 in any filing by NET or
YouthStream with the SEC.

                           5.18 Listing on NASDAQ. NET shall cause the shares
of NET common stock to be issued at the Effective Time to be listed on NASDAQ

contemplated by this agreement with knowledge of any breach or
misrepresentation by Newco or NET.

                           8.2      Indemnification.

                                    (a) The Company and NET shall be
indemnified and held harmless, solely out of the shares of NET common stock and
Convertible Preferred Stock held pursuant to the Escrow Agreement, against all
loss, liability, damage or expense (including reasonable fees and expenses of
counsel, whether involving a third party or between the parties to this
agreement) (collectively, "Losses") the Company or NET may suffer, sustain or
become subject to as a result of any breach of any representation, warranty,
covenant or other agreement of the Company contained in this agreement, or any
misrepresentation by the Company, or any claim by a third party which without
regard to the merits of the claim would constitute such a breach or
misrepresentation.

                                    (b) NET shall indemnify and hold harmless
the stockholders of the Company against all Losses the stockholders of the
Company may suffer, sustain or become subject to as a result of any breach of
any representation, warranty, covenant or other agreement of Newco or NET
contained in this agreement, or any misrepresentation by Newco or NET, or any
claim by a third party which, without regard to the merits of the claim, would
constitute such a breach or misrepresentation.

                           8.3 Limitations on Liability. Notwithstanding
anything to the contrary in this agreement, (a) no party shall be entitled to
indemnification for misrepresentation or breach of warranty unless the aggregate
Losses incurred as a result of all such misrepresentations and breaches of
warranty exceeds the sum of $500,000, in which event such party shall be
entitled to indemnification for all such Losses in excess of $500,000, (b) the
only recourse of NET and the Company for indemnification under this agreement
shall be to the shares of NET common stock and Convertible Preferred Stock held
pursuant to the Escrow Agreement and NET and the Company shall have no other
recourse against the stockholders of the Company with respect to such
indemnification obligations, and (c) for purposes of indemnification by the
stockholders of the Company, each share of NET common stock and Convertible
Preferred Stock held in escrow shall be valued at $24.00.

                           8.4 Defense of Claims. If any third-party claim is
made against any party that, if sustained, would give rise to a liability of
the other party, the party against whom


                                      25
<PAGE>

the claim is made shall promptly cause notice of the claim to be delivered to
the other party and shall afford the other party and its counsel, at the other
party's sole expense, the opportunity to join in defending or compromising the
claim.

                           8.5 Representatives. For purposes of any
indemnification claim, Andrew Weinreich and Matthew Cowan (or if either of them
ceases to act, a successor designated by the holders of a majority of the
shares of the Company's common stock) shall act as representatives (the
"Representatives") of the stockholders of the Company, and shall have full
authority, on behalf of all of the stockholders of the Company, to make any
determination or to settle any claim pursuant to this section 8. By approving
the Merger, the stockholders of the Company shall be deemed to have confirmed
the appointment and authority of the Representatives, and NET shall be entitled
to rely on the Representatives' authority. The Representatives in acting for
the stockholders of the Company shall have no liability unless they are guilty
