      2.1   Closing Transactions. Subject to the terms and conditions set forth
in this Agreement (including Section 7.4 hereof):

            (a)   Surrender of Stock. AWS PCS hereby agrees to surrender, assign
and deliver to Triton at the Closing, and Triton agrees to accept from AWS PCS
at the Closing, the Stock, free and clear of all claims, liabilities, security
interests, mortgages, liens, pledges, conditions, charges or encumbrances of any
nature whatsoever other those created by or in favor of Triton or its Affiliates
(collectively, "Liens") if the Stock has not been previously delivered pursuant
to Section 7.4. AWS PCS and Triton agree that such surrender, assignment and
delivery of the Stock shall be deemed to have been consummated at the Closing
immediately after, and solely in consideration of, the termination of the
Stockholders Agreement contemplated by Section 2.1(b). At the Closing, AWS PCS
shall deliver to Triton the certificates representing the Stock, together with
executed stock powers in blank for each certificate delivered. Effective upon
such surrender, assignment and delivery, Triton shall cancel such stock
certificates and return the Stock to the status of treasury shares.

            (b)   Termination of Stockholders Agreement. Triton hereby
acknowledges and agrees (i) that as of the date hereof the requisite parties to
the Stockholders Agreement have executed and delivered an amendment to the
Stockholders Agreement, attached hereto as Exhibit 2.1(b) (the "Amendment to the
Stockholders Agreement"), which has amended (A) Article 4 of the Stockholders
Agreement to provide that the transactions contemplated in this Agreement shall
not be subject to the restrictions and obligations relating to the transfer of
Stock contained in the Stockholders Agreement and (B) Section 12.3 of the
Stockholders Agreement to provide that the delivery and surrender of the Stock
pursuant to Section 2.1 or Section 7.4 of this Agreement or Triton's failure to
accept delivery of the Stock in the manner contemplated by Section 2.1 or
Section 7.4 of this Agreement, for any reason, shall be additional events that
shall cause the termination of the Stockholders Agreement and (ii) that the
delivery and surrender of the Stock pursuant to Section 2.1 or Section 7.4 of
this Agreement or Triton's failure to accept delivery of the Stock in the manner
contemplated by Section 2.1 or Section 7.4 of this Agreement, for any reason,
shall cause the termination of the Stockholders Agreement.

            (c)   Affiliate License Co., L.L.C. At the Closing, AWS agrees to
sell, convey, transfer, assign and deliver to Triton all of AWS's limited
liability company membership interests in Affiliate License Co., L.L.C., free
and clear of all Liens, and thereafter the parties agree that, except for
obligations and restrictions arising under Article 9 of the Operating Agreement
of Affiliate License Co. and under Sections 6 and 9 of the Amended and Restated
Agreement dated as of April 16, 1999 (the "Affiliate License Co. Agreement")
among Tritel Communications, Inc. (as

                                      -5-

<PAGE>

predecessor in interest to AWS), Telecorp Communications, Inc. (as predecessor
in interest to AWS) and Triton PCS, Inc. (which shall remain in full force and
effect), neither AWS nor AWS PCS will be subject to any obligations or
restrictions imposed in connection with, or as a result of, its prior ownership
of its limited liability company membership interest in Affiliate License Co.,
L.L.C. At the request of Triton, AWS agrees to take all actions necessary to
terminate the Affiliate License Co. Agreement with respect to AWS effective upon
the Closing, other than Sections 6 and 9 thereof, and to transfer and assign to
Triton PCS, Inc. all of AWS's right, title and interest in and to the
trademarks, trade names and services marks containing the word "SUNCOM" or
derivatives thereof (collectively, the "SUNCOM Marks"). Triton shall prepare or
cause to be prepared and timely file or cause to be timely filed all tax returns
for Affiliate License Co., L.L.C. with respect to taxable periods ending on or
before the Closing Date that are required to be filed after the Closing Date
("Final Tax Returns"), in accordance with the following:

            (i)   any such Final Tax Returns shall, to the extent permitted by
applicable tax law, be prepared on a basis consistent with the last previous tax
returns filed for Affiliate License Co., L.L.C. (copies of which have been
furnished by AWS to Triton) and

            (ii)  Triton shall submit or cause to be submitted a draft of the
Final Tax Returns (including the underlying workpapers) to Cingular at least
thirty (30) days prior to the due date for their approval. Cingular shall have
the right to conduct a reasonable review of the Final Tax Returns prepared by
Triton, and Triton shall not file (or cause to be filed) such Final Tax Returns
without the prior written consent of AWS PCS, which consent shall not be
unreasonably withheld or delayed. If Cingular disagrees with any material tax
item or amount on the Final Tax Returns, Cingular and Triton shall in good faith
use their commercially reasonable efforts to reach agreement on the disputed tax
items or amounts.

Allocations of items of income and gain and loss and deduction of Affiliate
License Co., L.L.C. for the taxable period ending on the Closing Date shall be
made using the closing-of-the-books method. Triton shall cause an election under
Section 754 of the Code to be in effect for the taxable year in which the
Closing occurs.

            (d)   Deferral of Dividend Payment; Waiver. The parties acknowledge
that Triton's Board of Directors declared on February 25, 2004 the payment of a
quarterly cash dividend on Triton's Series A Preferred Stock (the "Dividend"),
which Dividend is payable to AWS PCS, as the sole shareholder of Series A
Preferred Stock as of the record date of March 31, 2004, and that Triton has not
yet paid such Dividend to AWS PCS. The parties agree that Triton may continue to
defer the payment of the Dividend to AWS PCS pending the Closing of this
Agreement or the earlier delivery of the Stock to Triton under the circumstances
expressly permitted in Section 7.4 hereunder. Effective as of the Closing or
such earlier delivery of the Stock to Triton, each of Cingular, AWS and AWS PCS
hereby irrevocably waives any claim and any right, title and interest in and to
the Dividend, provided, however, such waiver will not, in any way, affect any
other rights of the holders of the Series A Preferred Stock, including, without
limitation, the right to receive cumulative dividends (including cumulative
dividends on the Dividend) that accrue during the period prior to Closing or the
earlier delivery of the Stock to Triton under the circumstances expressly
permitted in Section 7.4 hereunder. In connection with such Dividend payment
deferral and waiver, each of Cingular, AWS and AWS PCS further represents,
warrants and covenants to Triton that it has not taken any action to assign, and
has

                                      -6-
<PAGE>

not assigned, to any other Person any of such party's respective right, title or
interest in and to all or any portion of the Dividend and that it will make no
such assignment prior to the Closing or the earlier delivery of the Stock to
Triton under the circumstances expressly permitted in Section 7.4 hereunder. The
waiver provided by AWS PCS hereunder shall terminate in the event that this

      7.1   Interim Period. Between the date of this Agreement and the Closing
Date, except as contemplated by this Agreement:

            (a)   AWS PCS shall not sell, assign, lease or otherwise transfer or

Agreement and such other party's officers, employees, agents, counsel,
accountants and other Representatives, reasonable access during normal business
hours upon reasonable prior notice and approval, which shall not be unreasonably
withheld, to all of such party's records and information that such other party
reasonably requests as may be reasonably necessary in connection with the
consummation of the transactions contemplated by the Transaction Documents;
provided, that any inspection of another party's properties or discussion with
another party's personnel shall occur only if a Representative designated by
such other party is present. All such information provided pursuant to this
Section 7.2 shall be subject to the Confidentiality Agreement. The rights of the
parties under this Section 7.2 shall not be exercised in such a manner as to
interfere unreasonably with the business or operations of any party or for any
purpose other than in connection with the consummation of the transactions
contemplated by this Agreement.

      7.3   Waiver by AWS PCS, Etc. From and after the date hereof, AWS PCS
does, and shall cause its controlled Affiliates to waive Triton's compliance
with Section 7.11 and Section 8.4 of the Stockholders Agreement and all other
provisions of the Stockholders Agreement that may limit the ability of Triton
and its controlled Affiliates to acquire and hold (but not to operate) spectrum
or related FCC licenses for spectrum in markets that are outside of the
Territory (as defined in the Stockholders Agreement), including the Lafayette
License (as defined under the License Exchange Agreement); provided, however,
such waiver shall not, in any way, affect or amend the definition of Territory
in the Stockholders Agreement.

      7.4   Delivery of the Stock and License Company Interests to Triton In
Certain Circumstances.

            (a)   Notwithstanding any other provision of this Agreement and
without regard to the satisfaction of the closing conditions set forth in
Article 10 hereof, AWS PCS shall surrender, assign and deliver (at the Triton
address set forth in Section 14.2) the Stock to Triton upon the closing of the
Merger, in the manner contemplated under Section 2.1(a) hereof, with the

                                      -10-

<PAGE>

Stock being free and clear of all Liens, and Triton shall be required to accept,
and shall be deemed to have accepted, the Stock after AWS PCS has delivered to
Triton the certificates representing the Stock, together with endorsed stock
powers in blank for each certificate.

            (b)   Notwithstanding any other provision of this Agreement AWS PCS
shall have the right to surrender, assign and deliver (at the Triton address set
forth in Section 14.2) the Stock to Triton at any time prior to or following the
closing of the Merger, in the manner contemplated under Section 2.1(a) hereof
(but without giving effect to the references to the term "Closing," which shall
be deemed to be removed from Section 2.1(a) for purposes of this section), so
long as the Stock is free and clear of all Liens, and Triton shall be required
to accept, and shall be deemed to have accepted, the Stock after AWS PCS has
delivered to Triton the certificates representing the Stock, together with
endorsed stock powers in blank for each certificate. This Section 7.4(b) shall
survive indefinitely any termination of this Agreement or any of the other
Transaction Documents other than Triton's termination of this Agreement pursuant
to Section 12.1(a)(iv).

            (c)   The delivery of the Stock, free and clear of all Liens, by AWS
PCS to Triton in the manner contemplated under this Section 7.4 shall be deemed
to be a Closing for purposes of Section 2.1(a) hereof and shall cause the
immediate termination of the Stockholders Agreement, in accordance with terms of
the Amendment to the Stockholders Agreement and Section 2.1(b). In addition, as
set forth in the Amendment to the Stockholders Agreement, in the event that
Triton fails to accept delivery of the Stock in the manner contemplated by this
Section 7.4 or at the Closing, for any reason, then such failure shall cause the
immediate termination of the Stockholders Agreement and, upon the termination of
the Stockholders Agreement, Triton agrees that the Stock shall be transferable
free of the restrictions on transferability contained in the Stockholders
Agreement, in this Agreement or in the provisions of any other agreement between
Triton and its controlled Affiliates, on the one hand, and AWS PCS and its
Affiliates, on the other hand.

            (d)   AWS further agrees that, concurrently with any delivery of the
Stock to Triton contemplated under Section 7.4(a) or Section 7.4(b), AWS also
shall surrender, assign and deliver the License Company Interests to Triton,
free and clear of all Liens, and Triton shall be required to accept, and shall
be deemed to have accepted, the License Company Interests after AWS PCS has
delivered to Triton an executed Assignment. Notwithstanding any other provision
of this Agreement, the failure of AWS to effect delivery of the License Company
Interests, free and clear of all Liens, or the delivery of the Assignment
concurrently with any such delivery of the Stock shall not affect the validity
of such delivery and acceptance of the Stock, and such concurrent delivery of
the License Company Interests shall not otherwise be a condition to Triton's
obligations under Section 7.4(a) or Section 7.4(b) to accept delivery of the
Stock. Notwithstanding the foregoing, however, if AWS fails to effect delivery
of the License Company Interests, free and clear of all Liens, or the delivery
of the executed Assignment, Triton shall continue to have all rights and
remedies to seek enforcement of such obligation to deliver the License Company
Interests and the Assignment, and nothing in this Section 7.4 is intended to
relieve any party of any liability or obligation to effect at the Closing any of
the other transactions contemplated under any of the other provisions of this
Agreement or the Transaction Documents in accordance with their respective
terms.

            (e)   In the event of the surrender, assignment and delivery of the
Stock by AWS PCS to Triton and concurrent termination of the Stockholders
Agreement under this Section 7.4 , the surrender, assignment and delivery of the
Stock and termination of the Stockholders Agreement shall be viewed as being in
the nature of liquidated damages because of the difficulty of estimating the
damages which would result and not as a penalty with respect to the obligations
of any of Triton, Cingular, AWS and AWS PCS under Sections 2.1(a) and 2.1(b)
hereof, and thereafter none of Cingular, AWS, AWS PCS or Triton shall pursue any
other right or remedy that may be available to it against another party hereto
that directly relates to the Stock or the Stockholders Agreement.; provided,
however, that nothing in this Section 7.4 is intended to relieve any party of
any liability or obligation to effect any of the other transactions contemplated
under any of the other provisions of this Agreement (including the other
provisions of Section 2.1 or the provisions of Section 7.4(f)) or the
Transaction Documents and the parties shall reserve such other rights and
remedies as they may have at law or in equity against any other party hereto to
seek to enforce such other provisions. Notwithstanding such reservation of
rights and remedies with respect to the other provisions of this Agreement and
the Transaction Documents, Triton shall not pursue such rights and remedies in a
manner that could reasonably be expected to interfere with the ability of any of
Cingular, AWS or AWS PCS to effectuate the Merger.

            (f)   Notwithstanding any other provision of this Agreement or the
termination of the Stockholders Agreement in accordance with the terms hereof,
in the event that the surrender, assignment and delivery of the Stock by AWS PCS
to Triton and Triton's concurrent acceptance of such Stock occurs both prior to
the closing of the Merger and prior to a Disqualifying Event (as defined below),
then each of AWS, AWS PCS and their respective Affiliates shall continue to be
bound by, and shall be obligated to comply fully and in all respects with, the
provisions set forth in Section 8.6(b) of the Stockholders Agreement until the
earlier of a Disqualifying Event or the closing of the Merger occurs. As used
herein a "Disqualifying Event" shall mean any of the following: (i) a breach by
Triton or its Affiliates of Section 7.5 hereof; (ii) a material breach by Triton
of any of the representations contained in Sections 6.3, 6.4 or 6.5 hereof; or
(iii) a Triton Bankruptcy.

            7.5   Covenant Not to Sue; No Objection to the Merger. Triton, on
behalf of itself and its Affiliates, hereby covenants and agrees not to bring,
commence, prosecute, maintain or cause or permit to be brought, commenced,
prosecuted or maintained any suit, action or proceeding, either at law or in
equity, in any court or before any other Governmental Authority (i) regarding
the Merger or on account of Cingular's acquisition of AWS and AWS PCS or (ii)
challenging the enforceability of Sections 7.4 or 7.5 hereof, including without
limitation a filing at the FCC with respect to, or otherwise seek to cause any
Governmental Authority to refuse to issue its Consent to, the Merger. The
foregoing covenant not to sue may be raised or pleaded in any action or other
proceeding which may be brought, instituted or taken by any party or its
predecessors, successors or assigns and all past and present shareholders,
directors, officers, agents, Affiliates, heirs, and personal Representatives.
The foregoing covenant not to sue shall not be deemed or construed to be an
acknowledgement or agreement by Cingular, AWS or AWS PCS that Triton has any
claim or standing to challenge the Merger in any way.

                                 CONFIDENTIALITY

      8.1   Confidentiality. AWS, Cingular and Triton are parties to the
Confidentiality Agreement, and the disclosure of this Agreement, or of the terms
hereof or the existence of the transactions contemplated hereby, shall be
governed by the terms of the Confidentiality Agreement. Notwithstanding the
execution, delivery and performance of this Agreement or the termination of this
Agreement prior to Closing in accordance with Article 12, the Confidentiality
Agreement shall remain in full force and effect in accordance with its terms,
but shall expire concurrently with the Closing hereunder.

                                    ARTICLE 9

                                 JOINT COVENANTS

      Subject to the provisions of Section 7.4, each of the parties to this
Agreement covenant and agree as follows:

      9.1   Cooperation. Without limiting any of the obligations of the parties
hereunder, each of the parties to this Agreement shall cooperate fully with each
other and their respective counsel, accountants, agents and other
Representatives in all commercially reasonable respects in connection with any
actions required to be taken as part of their respective obligations under the
Transaction Documents, and the parties hereto shall use their commercially
reasonable efforts to consummate the transactions contemplated hereby and to
fulfill their respective obligations under the Transaction Documents as
expeditiously as practicable, provided, however, neither Cingular, AWS nor AWS
PCS shall have any obligation to Triton or its Affiliates to cause the closing
of the Merger. Subject to the terms and conditions of this Agreement, from time
to time prior to, at and after the Closing, each party hereto will use
commercially reasonable efforts to take, or cause to be taken, all such actions
and to do or cause to be done, all things, necessary, proper or advisable under
applicable Legal Requirements and regulations to consummate and make effective
the transactions contemplated by the Transaction Documents, including, without
limitation, executing and delivering such documents as any of the other parties
being advised by counsel shall reasonably request in connection with the
consummation of this Agreement. After the Closing, each of the parties to this
Agreement will execute any further documents consistent with the Transaction
Documents, provide any further reasonably available information, and take any
other actions not imposing significant financial or operational obligations in
excess of the other obligations imposed by the Transaction Documents, upon the
request of any other party to this Agreement based upon any such other party's
reasonable determination that those actions are required to enable such other
party to effectuate the Transaction Documents. No party to this Agreement shall
take any action which is materially inconsistent with its obligations under the
Transaction Documents. Each party to this Agreement shall notify each other
party to this Agreement of any litigation, arbitration or administrative
proceeding pending or, to its knowledge, threatened, which challenges any of the
transactions contemplated by the Transaction Documents or which threatens to
delay them, and shall use commercially reasonable efforts to take such steps as
may be necessary to remove any such impediment to the consummation of the
transactions contemplated by the Transaction Documents.

                                      -13-

<PAGE>

      9.2   Consents. Each party to this Agreement shall diligently make and
cooperate with the other parties to this Agreement in using all commercially
reasonable efforts to obtain or cause to be obtained prior to the Closing all
Consents which have not been obtained on or before the date of this Agreement.

      9.3   Public Announcements. No party to this Agreement will issue any
press release or make any other public announcements concerning this Agreement
or any of the other Transaction Documents or the transactions contemplated
hereby or thereby except with the prior approval (not to be unreasonably
withheld or delayed) of the other parties; provided, however, that if any such
disclosure is required by any applicable Legal Requirements or the rules or
regulations of any securities exchange, such consent shall not be required, but,
in such circumstances no party hereto will make such disclosure without first
providing to the other parties an advance copy of any such disclosure and a
reasonable opportunity to review and comment, to the extent practicable.
Notwithstanding anything to the contrary contained herein, the parties hereto
shall use commercially reasonable efforts to prepare and issue a press release
with respect to the transactions contemplated by this Agreement upon the
execution and delivery of this Agreement.

set forth in Section 10.1(b), if such party shall not have used commercially
reasonable efforts to prevent the entry of such judgment, injunction,
restraining order or decree and to appeal as expeditiously as reasonably

relating to this Agreement or any of the transactions contemplated hereby and
each party hereby irrevocably agrees that all claims in respect of such dispute
or any suit, action or proceeding related thereto may be heard and determined in
such courts. The parties hereby irrevocably waive, to the fullest extent
permitted by applicable law, any objection which they may now or hereafter have

agreement, written or oral, discussion, or negotiation not expressly contained
herein in entering into this Agreement or the Transaction Documents. Each party
hereby represents, acknowledges and agrees that, except as otherwise expressly

same effect as if the signature on each counterpart were upon the same
instrument.

      14.7  Severability. If any provision of this Agreement or the application
thereof to any Person or circumstance shall be invalid or unenforceable to any
extent, the remainder of this Agreement and the application of such provision to
other Persons or circumstances shall not be affected thereby and shall be
enforced to the greatest extent permitted by law. Upon such determination that
any term or other provision is invalid or unenforceable, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner to
the end that the transactions contemplated hereby are fulfilled to the greatest
extent possible.

            (a)   Amendment of Cingular Roamer Agreements. Cingular and Triton
hereby amend, effective upon the Closing (or such earlier date as is provided in

in the event that AWS PCS has delivered to Triton PCS Holdings, Inc. the Stock

consummation of the Merger, the AWS Roamer Agreements shall be terminated and
the Cingular Roamer Agreements, as amended hereby, shall govern roaming

booklets, brochures, pamphlets, network maps and charts) and website collateral

roaming coverage is provided for Triton customers primarily (but not
exclusively) through Cingular.

agree that neither of such parties shall take any action to terminate the
Network Membership License Agreement dated as of February 4, 1998, as amended,
prior to February 4, 2005; provided, however, nothing contained herein or in the

right or obligation of any party to the Network Membership License Agreement
including, without limitation, the rights contained in Section 11.1 of the
Network Membership License Agreement regarding the renewal of the term of
Network Membership License Agreement.

      2.2   Acceleration of Effectiveness of Cingular Amendment Terms Under
Certain Circumstances. Notwithstanding any provision to the contrary contained

accordance with the terms of the Triton PCS Holdings Agreement, and (i) Triton
or any of its Affiliates breaches Section 5.2 hereof, or (ii) there is a
material breach by Triton of any of the representations contained in Sections
4.3, 4.4, or 4.5 hereof, or (iii) there is a Triton Bankruptcy, then the
Cingular Amendment Terms and the provisions of Section 2.1(b) shall become
immediately effective, and shall be in full force and effect without any further
action and shall survive any termination of this Agreement or of the Triton PCS

contained herein, in the event that Triton PCS Holdings, Inc. fails to accept,
for any reason, the Stock, as defined under the Triton PCS Holdings Agreement,

full force and effect without any further action and shall survive any
termination of this Agreement or of the Triton PCS Holdings Agreement.

provisions of Section 2.1(b) in accordance with Section 2.2, the AWS Roamer
Agreements shall be amended, automatically and without any further action by AWS
or Triton, to incorporate the terms and conditions set forth in Schedule 2.3

assigns and all past and present shareholders, directors, officers, agents,

Cingular, AWS or AWS PCS that Triton has any claim or standing to challenge the
Merger in any way.

                                   ARTICLE 6

                                 CONFIDENTIALITY

      6.1   Confidentiality. AWS, Cingular and Triton PCS Holdings, Inc., the
corporate parent of Triton, are parties to the Confidentiality Agreement, and
the disclosure of this Agreement, or of the terms hereof or the existence of the
transactions contemplated hereby, shall be governed by the terms of the
Confidentiality Agreement. Notwithstanding the execution, delivery and
performance of this Agreement or the termination of this Agreement prior to
Closing in accordance with Article 10, the Confidentiality Agreement shall
remain in full force and effect in accordance with its terms, but shall expire
concurrently with the Closing hereunder.

                                   ARTICLE 7

                                 JOINT COVENANTS

      Each of the parties to this Agreement covenant and agree as follows:

      7.1   Cooperation. Without limiting any of the obligations of the parties
hereunder, each of the parties to this Agreement shall cooperate fully with each
other and their respective counsel, accountants, agents and other
Representatives in all commercially reasonable respects in connection with any
actions required to be taken as part of their respective obligations under the
Transaction Documents, and the parties hereto shall use their commercially
reasonable efforts to consummate the transactions contemplated hereby and to
fulfill their respective obligations under the Transaction Documents as
expeditiously as practicable provided, however, neither Cingular, AWS, nor AWS
PCS shall have any obligation to Triton or its Affiliates to cause the closing
of the Merger. Subject to the terms and conditions of this Agreement, from time
to time prior to, at and after the Closing, each party hereto will use
commercially reasonable efforts to

                                      -9-

<PAGE>

take, or cause to be taken, all such actions and to do or cause to be done, all
things, necessary, proper or advisable under applicable Legal Requirements and
regulations to consummate and make effective the transactions contemplated by
the Transaction Documents, including, without limitation, executing and
delivering such documents as any of the other parties being advised by counsel
shall reasonably request in connection with the consummation of this Agreement.
After the Closing, each of the parties to this Agreement will execute any
further documents consistent with the Transaction Documents, provide any further
reasonably available information, and take any other actions not imposing
significant financial or operational obligations in excess of the other
obligations imposed by the Transaction Documents, upon the request of any other
party to this Agreement based upon any such other party's reasonable
determination that those actions are required to enable such other party to
effectuate the Transaction Documents. No party to this Agreement shall take any
action which is materially inconsistent with its obligations under the
Transaction Documents. Each party to this Agreement shall notify each other
party to this Agreement of any litigation, arbitration or administrative
proceeding pending or, to its knowledge, threatened, which challenges any of the
transactions contemplated by the Transaction Documents or which threatens to
delay them, and shall use commercially reasonable efforts to take such steps as
may be necessary to remove any such impediment to the consummation of the
transactions contemplated by the Transaction Documents.

      7.2   Consents. Each party to this Agreement shall diligently make and
cooperate with the other parties to this Agreement in using all commercially
reasonable efforts to obtain or cause to be obtained prior to the Closing all
Consents which have not been obtained on or before the date of this Agreement.

      7.3   Public Announcements. No party to this Agreement will issue any
press release or make any other public announcements concerning this Agreement
or any of the other Transaction Documents or the transactions contemplated
hereby or thereby except with the prior approval (not to be unreasonably
withheld or delayed) of the other parties; provided, however, that if any such
disclosure is required by any applicable Legal Requirements or the rules or
regulations of any securities exchange, such consent shall not be required, but,
in such circumstances no party hereto will make such disclosure without first
providing to the other parties an advance copy of any such disclosure and a
reasonable opportunity to review and comment, to the extent practicable.
Notwithstanding anything to the contrary contained herein, the parties hereto
shall use commercially reasonable efforts to prepare and issue a press release
with respect to the transactions contemplated by this Agreement and the License
Exchange Agreement upon the execution and delivery of this Agreement and the
License Exchange Agreement.

to this Agreement made in this Agreement shall be true and correct in all

relate to an earlier date in which case such representations and warranties
shall be true and correct in all material respects on and as of such earlier
date and except in each case for changes contemplated by this Agreement.

                  (ii)  All of the covenants and agreements of the other parties
to this Agreement contained in this Agreement to be complied with and performed

discretion, waive any condition to its obligation to consummate the transactions
contemplated by this Agreement. No party to this Agreement may rely on the
failure of any condition set forth in this Article 8 to be satisfied if the
failure of such condition to be satisfied is the result of the breach of this
Agreement by such party or, in the case of a non-fulfillment of the condition
set forth in Section 8.1(b), if such party shall not have used commercially
reasonable efforts to prevent the entry of such judgment, injunction,
restraining order or decree and to appeal as expeditiously as reasonably

contemplated hereby and each party hereby irrevocably agrees that all claims in
respect of such dispute or any suit, action proceeding related thereto may be
heard and determined in such courts. The parties hereby irrevocably waive, to
the fullest extent permitted by applicable law, any objection which they may now
or hereafter have to the laying of venue of any such dispute brought in such
court or any defense of inconvenient forum for the maintenance of such dispute.
Each of the parties hereto agrees that a judgment in any such dispute may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law.

      12.5  Entire Agreement. This Agreement, the other Transaction Documents
and the Schedules and Exhibits hereto and thereto collectively represent the

matter of this Agreement. This Agreement supersedes all prior representations,
warranties, covenants, understandings, agreements, written or oral, discussions,

that makes specific reference to this Agreement and that is signed by each of
the parties hereto. Each party hereby represents, acknowledges and agrees that
it has not relied on any representation, warranty, covenant, understanding,
agreement, written or oral, discussion, or negotiation not expressly contained
herein in entering into this Agreement or the Transaction Documents. Each party
hereby represents, acknowledges and agrees that, except as otherwise expressly
stated herein, this Agreement and the other Transaction Documents are
independent of, and not in any way conditioned on or to be construed with any
other agreement or arrangement, written or oral, between the parties including,
but not limited to, that certain non-binding letter of intent between the
parties dated as of the date hereof and the transactions contemplated thereby.

      12.6  Counterparts. This Agreement may be signed in counterparts with the
same effect as if the signature on each counterpart were upon the same
instrument.

      12.7  Severability. If any provision of this Agreement or the application
thereof to any Person or circumstance shall be invalid or unenforceable to any
extent, the remainder of this Agreement and the application of such provision to
other Persons or circumstances shall not be affected thereby and shall be
enforced to the greatest extent permitted by law. Upon such determination that
any term or other provision is invalid or unenforceable, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner to
the end that the transactions contemplated hereby are fulfilled to the greatest
extent possible.
