                                 TRUST AGREEMENT

          THIS TRUST AGREEMENT (the "Trust Agreement") is entered into as of
August 28, 2000, and is effective at 12:01 a.m. local time on August 29, 2000,
by and among Clear Channel Communications, Inc., a Texas corporation ("CCC"),
Clear Channel Broadcasting, Inc., a Nevada corporation ("CCB"), Clear Channel
Broadcasting Licenses, Inc., a Nevada corporation ("CCBL") (CCB and CCBL,
collectively, the "Clear Channel Subs" and CCC and the Clear Channel Subs,
collectively, "Clear Channel"), AMFM Radio Licenses, L.L.C., a Delaware limited
liability company ("AMFM Radio"), AMFM Ohio, Inc., a Delaware corporation ("AMFM
Ohio"), Capstar TX Limited Partnership, a Delaware limited partnership ("Capstar
TX"), Capstar Radio Operating Company, a Delaware corporation ("Capstar Radio")
(AMFM Radio, AMFM Ohio, Capstar TX and Capstar Radio, collectively, the "AMFM
Subs" and the AMFM Subs and the Clear Channel Subs, collectively, the "Subs")
and Charles E. Giddens (the "Trustee").

                                    RECITALS

     A. Pursuant to the October 2, 1999 Agreement and Plan of Merger among CCC,
CCU Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of
CCC ("Merger Sub"), and AMFM Inc., a Delaware corporation ("AMFM") (the "Merger
Agreement"), Merger Sub is to merge with and into AMFM (the "Merger"). Following
the Merger, AMFM will be a wholly-owned subsidiary of CCC, and each of the AMFM
Subs will be controlled by CCC.

     B. One or more Subs own the assets and hold the FCC licenses used in the
operation of the radio broadcast stations listed in Attachment I to this
Agreement, which stations are licensed to certain communities and located in
certain areas as set forth in Attachment I.

     C. The stations listed in Attachment I shall be referred to collectively
herein as the "Stations".

     D. The Communications Act of 1934, as amended, and the rules, regulations
and policies of the FCC (collectively, the "Communications Act"), and/or
concerns of the United States Department of Justice ("DOJ"), do not permit the
common ownership of all of the radio stations controlled by AMFM and by Clear
Channel in the areas served by the Stations (collectively, the "Relevant
Areas").

     E. Clear Channel and AMFM (or one or more subsidiaries thereof) have
entered or intend to enter into one or more agreements to sell certain radio
stations in the Relevant Areas in order to comply with the Communications Act
and any requirements of DOJ. In the event that such sales cannot be consummated
prior to or contemporaneously with consummation of the Merger, interim
acquisition by the Trustee, for the benefit of Clear Channel, of the assets of
the Stations would provide an appropriate mechanism to facilitate consummation
of the Merger in a manner that complies with the laws and regulations relating
to transactions of this type. In the event that Clear Channel decides instead to
(i) request the Trustee to sell the Stations' Assets (defined below) relating to
one, some or all of the Stations pursuant to Section 3(e), and the

<PAGE>   2

Trustee concurs with the decision; or (ii) request the Trustee to reconvey the
Stations' Assets relating to one, some or all of the Stations to Clear Channel
pursuant to Section 3(h), then the Trustee agrees to use his best efforts
promptly and diligently to apply to the FCC for consent to the assignment of the
appropriate Stations' Assets and prosecute such applications.

     Therefore, the parties agree as follows:

                                    AGREEMENT

     1. Creation and Purpose of The CCU/AMFM Trust I. Subject to the terms and
conditions hereof, a trust in respect of the Stations' Assets is hereby created
and established, to be known as the "The CCU/AMFM Trust I," and the Trustee
hereby accepts the trust created hereby and agrees to serve as trustee
hereunder. The trust created hereby shall be irrevocable until such time as the
Communications Act is satisfied with respect to Clear Channel's ownership of
multiple radio broadcast stations in the Relevant Areas.

     2. Assets to be Conveyed; Assumption of Obligations. Upon the effectiveness
of this Trust Agreement, the Subs will transfer and convey to Trustee, and
Trustee shall acquire from the Subs, all of the assets, real, personal and
mixed, tangible and intangible (including the business of the Stations as a
going concern), owned or held by the Subs, and used, useful or necessary in the
conduct of the business and operation of the Stations, including, but not
limited to, the following:

          (a) all of the Subs' right, title and interest in and to the licenses,
permits and other authorizations issued by any governmental authority and used,
useful or necessary in the conduct of the business and operation of the
Stations, including the Stations' call letters, and any applications for such
licenses, permits and authorizations;

          (b) all of the Subs' right, title and interest in and to all real
property, including leasehold interests and easements, used, useful or necessary
in the conduct of the business and the operation of the Stations;

          (c) all equipment, office furniture and fixtures, office materials and
supplies, inventory, spare parts, motor vehicles and other tangible personal
property of every kind and description, owned, leased or held by the Subs and
used, useful or necessary in the conduct of the business and operation of the
Stations;

          (d) all cash in the Stations' operating bank accounts;

          (e) all accounts receivable arising out of the operation of the
Stations;

          (f) all of the Subs' rights under and interest in all contracts
relating to the conduct of the business of the Stations (but excluding any
contract or agreement for the sale of the Stations' Assets following termination
of the Trust created hereby). In those cases where any necessary consents,
assignments, releases and/or waivers necessary for the assignment of such

                                      -2-
<PAGE>   3

contracts have not been obtained at or prior to the date hereof, any assignment
of such contracts pursuant hereto, to the extent permitted by law, shall
constitute an equitable assignment by the applicable Sub to the Trustee of all
of such Sub's rights, benefits, title and interest in and to any such contract,
and where necessary or appropriate, the Trustee shall be deemed to be the
applicable Sub's agent for the purpose of completing, fulfilling and discharging
all of the applicable Sub's rights and liabilities arising from the date hereof
under any such contract;

          (g) all programs and programming materials of whatever form or nature
owned by the Subs and used or intended for use on or by the Stations;

          (h) all of the Subs' right, title and interest in and to the
trademarks, trade names, service marks, franchises, copyrights, including
registrations and applications for registration of any of them, jingles, logos,
slogans, licenses, permits and privileges owned or held by the Subs and used,
useful or necessary in the conduct of the business and operation of the
Stations;

          (i) all files, records, books of account, computer programs and
software and logs relating to the operation of the Stations, including, without
limitation, payable records, receivable records, invoices, statements, traffic
material, programming information and studies, technical information and
engineering data, news and advertising studies and consultants' reports, ratings
reports, marketing and demographic data, sales correspondence, lists of
advertisers, promotional materials, credit and sales reports, budgets, financial
reports and projections, sales, operating and business plans, filings with the
FCC and original executed copies of all written contracts to be assigned
hereunder;

          (j) all of the Subs' rights under manufacturers' and vendors'
warranties relating to items included in the Stations' Assets (defined below)
and all similar rights against third parties relating to items included in the
Stations' Assets to the extent contractually assignable; and

          (k) all of the above whether now owned or contracted for by the Subs
or hereafter acquired.

The assets to be transferred to Trustee hereunder are hereinafter collectively
referred to as the "Stations' Assets."

     The Trustee shall assume and undertake to pay, satisfy or discharge the
liabilities, obligations and commitments of the Stations under all of their
contracts, including time sales agreements and employment agreements.

     The Trustee shall retain and hold the Stations' Assets, and assume the
Stations' obligations, only in accordance with, and subject to the terms and
conditions set forth in, this Trust Agreement.

     3. Management and Other Actions by Trustee.

                                      -3-
<PAGE>   4

          (a) During the term of this Trust Agreement, the right to manage and
direct the management of the business of the Stations shall be solely vested in
the Trustee, subject to the following:

               (i) The Trustee shall conduct the operations of the Stations as a
radio broadcaster serving the Relevant Areas served by the Stations in the
ordinary course of business consistent with past operations of the Stations. To
the extent possible, the Trustee shall maintain the status quo of such
operations as currently operating with a view to maximizing the value to be
received by Clear Channel consistent with the Trustee's duties as a licensee of
the FCC and as a fiduciary of Clear Channel. With respect to so conducting the
operations and management of the Stations, Trustee shall provide CCC or its
designee with financial reports in form and substance and in such time frames as
are consistent with the practices established by Clear Channel for the Stations,
together with such other financial information as may be reasonably requested by
Clear Channel in order to meet its financial reporting requirements to its
accountants, lenders, the SEC and any other authorities of competent
jurisdiction. Trustee shall also provide CCC or its designee with monthly
budgets and estimates (which shall be prepared in a manner and within such time
frames as are consistent with the practices established by Clear Channel for the
Stations). Clear Channel shall not use or attempt to use these financial
materials to limit or restrict the Trustee's discretion to operate the Stations
in the manner described in this subsection;

               (ii) to the extent that the Stations' operations generate cash
accumulations in excess of the Stations' actual and projected expenses as
determined by the Trustee in his sole discretion ("Excess Cash Flow"), such
Excess Cash Flow shall be remitted to Clear Channel from time to time as the
Trustee shall determine;

               (iii) to the extent that the Trustee determines in his discretion
that management and operation of the Stations consistent with past practice or
payment of the charges and other expenses set forth in Section 4(c) hereof
requires funds in excess of the ordinary cash flow of the Stations (as
diminished by any prior remittance of Excess Cash Flow), the Trustee may request
in writing that Clear Channel advance to the Trustee funds in such amount as
will make up the deficiency (an "Advance"). Clear Channel shall, within ten days
of receipt of such request, provide such Advance to the Trustee in the amount
requested. Any Advance shall be repayable from Excess Cash Flow with interest at
prime plus one percent. Clear Channel shall not communicate directly or
indirectly with the Trustee about, or participate with the Trustee in making,
any decision to request an Advance or as to when or how the funds will be used.

               (iv) any employee hired by the Trustee who is not employed at the
Stations as of the effective date of this Trust Agreement shall not be a 1% or
greater shareholder, director, officer, or employee of Clear Channel or its
affiliates, and may not have any business or familial relationship (as defined
in the FCC Policy Statement in MM Docket No. 85-218, FCC 86-67 (March 17, 1986))
with Clear Channel or with any 1% or greater shareholder, director, officer, or
employee of Clear Channel or its affiliates.

                                      -4-
<PAGE>   5

          (b) The Trustee shall cause any employee hired by him pursuant to
Section 3(a)(iv), and any person previously employed by Clear Channel whom the
Trustee elects to retain, to execute and deliver to the Trustee an agreement, in
form and substance acceptable to the Trustee, pursuant to which such employee
agrees to comply with the rules, regulations and policies of the FCC, including
without limitation all rules, regulations and policies governing communications
among such employee and Clear Channel or its officers, directors, employees, and
affiliates (or any officer, director, or employee of any such affiliate),
regarding the Stations and their management and operations.

          (c) No person other than the Trustee or managers designated by the
Trustee shall have any authority with respect to the management of the Stations
or the Stations' Assets for so long as this Trust Agreement is in effect. The
Trustee shall have no beneficial interest in the Stations' Assets.

          (d) Except as expressly provided in this Trust Agreement, the Trustee
shall not: incur any debt or guaranty obligation in favor of any other person;
engage in any business other than as necessary in the Trustee's reasonable
opinion to meet his fiduciary duties with respect to the operation of the
Stations as a broadcast licensee serving the Relevant Areas served by the
Stations; sell or otherwise transfer, assign or encumber all or any significant
Stations' Assets, or enter into any agreement to do so; or enter into any
merger, consolidation, or similar transaction or engage in any reclassification
or similar transaction.

          (e) Clear Channel shall have the right to request the Trustee to sell
the Stations' Assets relating to one, some or all of the Stations to an
unaffiliated third party or parties. Within 24 hours of receipt of such a
request from Clear Channel, the Trustee shall advise Clear Channel whether he
concurs in such a sale. In the event the Trustee so concurs, the Trustee shall
have the authority to take all actions necessary or appropriate to effectuate
the transfer of title to the Stations' Assets relating to one, some or all of
the Stations held by the Trustee pursuant to this Trust Agreement to (and the
assumption of the liabilities, obligations and commitments of such Stations by)
an unaffiliated third party or parties. In this regard, the Trustee shall enter
into appropriate agreements, submit and fully prosecute appropriate applications
to the FCC requesting approval to assign the appropriate Stations' Assets, and,
following receipt of FCC consent and upon satisfaction of all closing conditions
not otherwise waived, transfer the appropriate Stations' Assets to the approved
assignee. To facilitate any sale or sales of the Stations' Assets to an
unaffiliated third party or parties (a "Sale"), the Trustee may request in
writing from Clear Channel such information, representations, warranties, and
indemnifications regarding operation of the appropriate Station or Stations as
may be needed to effectuate such Sale. During the time that the Trustee is
attempting to sell the Stations' Assets relating to one, some or all of the
Stations, the Trustee shall file monthly reports with Clear Channel (or more
frequent reports, as the Trustee shall deem appropriate) setting forth the
Trustee's efforts to sell such Stations' Assets. Within three (3) days following
execution of a binding agreement for a Sale, the Trustee shall notify Clear
Channel of the proposed Sale and provide Clear Channel with details of the
proposed transaction. Notwithstanding any other provision of this Trust
Agreement, Clear Channel shall have the right, with respect to any Sale: (i) to
require that the entire purchase price be paid at the closing of such Sale; (ii)
to require that

                                      -5-
<PAGE>   6

all Stations' Assets relating to one, some or all of the Stations be sold
together to a single purchaser and that such purchaser assume all of the
liabilities, obligations and commitments relating to such Stations' Assets
arising and accruing after the closing of such Sale; (iii) to establish a
minimum purchase price for the Sale or an acceptable exchange of Stations'
Assets for other assets; (iv) to require that any Sale include terms and
conditions that are customary in the sale or exchange of assets of radio
stations, including escrow arrangements, representations, covenants,
indemnities, remedies and termination provisions; (v) to establish a date by
which such Sale must be consummated; and (vi) to retain investment bankers to
assist in locating buyers for the Stations' Assets relating to any Station or
Stations; provided, however, that the Trustee shall be free to accept or reject
any advice offered by such investment bankers and shall be privy to any
instructions that Clear Channel may give to the investment bankers.
Notwithstanding any other provision of this Trust Agreement, Clear Channel shall
have the right, at any time prior to consummation of a Sale, to withdraw its
request that the Trustee sell the Stations' Assets relating to such Station or
Stations, subject to the independent concurrence of the Trustee with such
withdrawal; provided, however, that the Trustee shall be indemnified in
accordance with this Trust Agreement for any damages incurred by the Trustee as
a result of such withdrawal.

          (f) If prior to the execution of this Trust Agreement, Clear Channel
has entered into a binding agreement for a Sale (or Sales) of the Stations'
Assets relating to one, some or all of the Stations to a third party, and Clear
Channel so notifies the Trustee in writing and provides the Trustee with a copy
of such binding agreement, then the Trustee, acting for the benefit of Clear
Channel, shall sell such Stations' Assets as soon as practicable to such third
party consistent with the terms of the binding agreement.

          (g) Unless the Trustee does not concur in a request described in
Section 3(e) above, the Trustee shall use his best efforts promptly and
diligently to facilitate a Sale in accordance with Section 3(e) or 3(f).

          (h) In connection with a change in the Communications Act or the
disposition of a sufficient number of radio stations in one or more of the
Relevant Areas or otherwise, such that attribution of a particular Station or
Stations to Clear Channel would be permitted by the FCC, Clear Channel may
request the Trustee to reassign and retransfer the Stations' Assets relating to
a particular Station or Stations to Clear Channel or any direct or indirect
subsidiary of Clear Channel. Upon such request, the Trustee and Clear Channel,
to the extent necessary, shall submit and fully prosecute appropriate
applications to the FCC requesting approval to assign the licenses relating to
such Station or Stations to Clear Channel or such subsidiary, and, following
receipt of FCC consent, the Trustee shall transfer the Stations' Assets relating
to such Station or Stations, and the liabilities, obligations and commitments
relating to such Stations' Assets, to the approved assignee.

          (i) The Trustee shall have any and all such further powers and shall
take such further actions (including, but not limited to, taking legal action)
as may be necessary to fulfill the Trustee's obligations under this Trust
Agreement.

     4. Concerning the Trustee.

          (a) Subject to the provisions of this Trust Agreement, The CCU/AMFM
Trust I created hereby and the operations of the Stations shall be managed by
the Trustee, who shall comply in all material respects with the Communications
Act.

          (b) The Trustee shall be entitled to receive compensation for his
services hereunder as provided in the March 24, 2000 Engagement and Assignment
Agreement among the parties hereto and other parties (the "Engagement
Agreement"). The fee received by the Trustee pursuant to the first sentence of
paragraph 6 of the Engagement Agreement shall be credited toward any amounts
otherwise due hereunder, beginning with the initial invoice rendered pursuant to
this Section 4(b). The Trustee agrees that in return for such compensation, he
will devote such time to The CCU/AMFM Trust I as is necessary in the proper
exercise of his fiduciary duties hereunder. Payment of the Trustee's monthly
compensation shall be made by Clear Channel within 20 days after receipt of
appropriately detailed invoices therefor. Such invoices shall be rendered on a
monthly basis and upon the termination of this Trust Agreement under any of the
provisions of Section 5 hereof.

          (c) The Trustee is expressly authorized to incur and pay, from the
Stations' Assets held in trust, all reasonable charges and other expenses which
the Trustee deems necessary and proper in the performance of his duties under
this Trust Agreement, including fees and charges for legal counsel of his
choosing and the cost of any necessary secretarial staff. Clear Channel hereby
agrees to reimburse and to indemnify the Trustee against all claims, costs of
defense of claims, expenses, and liabilities (including reasonable attorneys'
fees, disbursements and taxes related to the CCU/AMFM Trust I, the Stations or
the Stations' Assets other than taxes of the Trustee individually calculated on
amounts paid hereunder) related to the CCU/AMFM Trust I, the Stations and the
Stations' Assets incurred by the Trustee in connection with the performance of
his duties under this Trust Agreement, except those incurred as a result of the
Trustee's gross negligence, intentional wrongful action or willful misconduct.
Payments to the Trustee pursuant to this Section 4(c) shall be made within 20
days of submission by the Trustee of an invoice or bill therefor, plus
appropriate supporting documentation. The obligations of Clear Channel to the
Trustee under this Section 4(c) shall survive the resignation, incapacity to
act, death or insolvency of the Trustee and the termination or revocation of
this Trust Agreement.

          (d) The Trustee shall be free from liability in acting upon any paper,
document or signature believed by the Trustee to be genuine and to have been
signed by the proper party. The Trustee shall not be liable for any error of
judgment in any act done or omitted, or for any mistake of fact or law, or for
anything which the Trustee may do or refrain from doing in good faith except for
intentional wrongful actions or gross negligence. The Trustee may consult with
legal counsel of his own choosing and any action under this Trust Agreement
taken or suffered in good faith by the Trustee and in accordance with the
opinion of the Trustee's counsel (if such opinion shall have been obtained by
Trustee) shall be conclusive on the parties to this Trust Agreement, and the
Trustee shall be fully protected and be subject to no liability in respect
thereto.

                                      -7-
<PAGE>   8

          (e) Subject to Section 4(c) hereof, the rights and duties of the
Trustee hereunder shall terminate upon the Trustee's incapacity to act, death or
insolvency, and no interest in any of the Stations' Assets directly or
indirectly held by the Trustee nor any of the rights and duties of a deceased or
insolvent Trustee may be transferred by will, devise, succession or in any
manner except as provided in this Trust Agreement. The heirs, administrators,
executors or other representatives of an incapacitated, deceased or insolvent
Trustee shall, however, have the right and duty to convey, subject to receipt of
any necessary FCC approval, any Stations' Assets held by the Trustee to one or
more successor Trustees designated by Clear Channel pursuant to Section 4(g)
below.

          (f) The Trustee may resign by giving not less than 60 days' advance
written notice of resignation to Clear Channel, provided that a successor
Trustee has been appointed, such appointment has received all necessary approval
from the FCC, and any order granting such approval has become a final order with
respect to which no action, request for stay, petition for hearing or
reconsideration, or appeal has been timely filed and is pending, and as to which
the time for filing any such request, petition or appeal has expired. Clear
Channel shall cooperate fully by prompt appointment of a successor Trustee and
shall not unreasonably interfere with or delay the effectiveness of such
resignation.

          (g) In the event of such resignation, incapacity to act, death or
insolvency of the Trustee, he shall be succeeded, subject to such prior approval
of the FCC as may be required, by a successor Trustee chosen by Clear Channel.
Any successor Trustee shall succeed to all of the rights and obligations of the
Trustee replaced hereunder upon execution by such successor Trustee of a
counterpart of this Trust Agreement.

          (h) The Trustee and any successor Trustee designated pursuant to
paragraphs (f) and (g) of this Section 4 shall not be a 1% or greater
shareholder, officer, employee, director, or affiliate of Clear Channel, and may
not have any business or familial relationship (as defined in the FCC Policy
Statement in MM Docket No. 85-218, FCC 86-67 (March 17, 1986)) with any officer,
employee, director, or 1% or greater shareholder or affiliate of Clear Channel,
nor shall the Trustee or any successor Trustee serve as an officer, employee, or
director of Clear Channel, its affiliates, or its successor companies following
any assignment specified in Section 3(e), Section 3(f) or Section 3(h).

          (i) It is understood and agreed by the parties that the Trustee's
principal business is as a media broker, which is separate from his duties as
Trustee, and the parties hereto have no intention of interfering in any manner
with the Trustee's media brokerage business. Thus, the Trustee may conduct his
activities with respect to Media Venture Partners, Inc. ("MVP"), unhindered by
this Trust Agreement and the Engagement Agreement. Nothing contained herein
shall prohibit or restrict Trustee as a principal of MVP or MVP from acting as a
broker, finder, consultant, or receiving compensation of any kind in connection
with the transfer of ownership (by assignment of license or transfer of control
of an existing entity) of any broadcast property in which Clear Channel or an
affiliate of Clear Channel is involved as buyer. Subject to the provisions of
Section 4(f) hereof, in the event MVP should be considered as a

                                      -8-
<PAGE>   9

broker for the sale of a broadcast property or properties in which Clear Channel
or an affiliate of Clear Channel is involved as a seller, the Trustee reserves
the right to resign as Trustee, and thereafter, the Trustee may participate in
the sale as a broker, finder, and/or consultant, and may receive compensation of
any kind as if this Trust Agreement and the Engagement Agreement had never
existed.

     5. Termination of Trust Agreement; Distribution of Proceeds of Sale of
Assets.

          (a) Subject to such FCC approval as may be required, and following the
receipt of such FCC approval, this Trust Agreement and The CCU/AMFM Trust I
created hereby shall terminate as to a Station or Stations, as the case may be,
upon the first to occur of the following: (i) the assignment of such Stations'
Assets as contemplated by Section 3(e) or Section 3(f) of this Trust Agreement;
or (ii) the retransfer of such Stations' Assets to Clear Channel or one or more
Clear Channel subsidiaries as contemplated by Section 3(h) of this Agreement.

          (b) Upon the termination of this Trust Agreement pursuant to Section
5(a)(i) hereof as to a Station or Stations, as the case may be, and consistent
with the requirements of the FCC, the Trustee shall deliver to the assignee(s)
those Stations' Assets contemplated by the assignment transaction that has been
approved by the FCC. In the case of a Sale of all or substantially all of the
Stations' Assets to an unaffiliated third party or parties pursuant to Section
3(e) or 3(f) of this Trust Agreement, the Trustee shall receive the money,
securities, rights or property which are distributed or are distributable in
respect of the Stations' Assets, and, after paying (or reserving for payment
thereof) any expenses or liability incurred pursuant to this Trust Agreement,
shall distribute or cause the distribution of such money, securities, rights or
property to Clear Channel or its designee.

          (c) Upon termination of this Trust Agreement pursuant to Section
5(a)(ii) hereof as to a Station or Stations, as the case may be, and consistent
with the requirements of the FCC, the Trustee shall, after paying (or reserving
for payment thereof) any expenses or liability incurred pursuant to this Trust
Agreement, deliver to CCC or the appropriate Clear Channel subsidiary or
subsidiaries those Stations' Assets contemplated by the assignment transaction
that has been approved by the FCC.

                                      -9-
<PAGE>   10

          (d) Upon completion of the deliveries and distributions set forth in
Section 5(b) or Section 5(c), as the case may be, with respect to all of the
Stations' Assets, the Trustee shall deliver all other property held by the
Trustee pursuant to this Trust Agreement to Clear Channel or its designee, and,
subject to Section 4(c) hereof, the rights and duties of the Trustee hereunder
shall terminate.

     6. Communications.

          (a) The Trustee may communicate with and provide reports (including
specifically the financial reports provided for in Section 3(a)(i)) to Clear
Channel concerning the implementation of The CCU/AMFM Trust I, but not
concerning the management and operations of the Stations except as provided in
Section 3(a)(i) above.

          (b) The Trustee may engage in the communications contemplated by
Section 3(e), Section 3(f) and Section 3(h) hereof to facilitate a Sale of
Stations' Assets to an unaffiliated third party (or parties) or a retransfer of
Stations' Assets to Clear Channel or subsidiaries thereof.

          (c) Neither Clear Channel nor any of its officers, directors,
employees, shareholders or affiliates (or any officer, director, employee or
shareholder of any such affiliate) shall communicate with the Trustee regarding
the operation or management of the Stations. Clear Channel may communicate with
the Trustee as provided in Section 3(e), Section 3(f) and Section 3(h) hereof,
and concerning the mechanics of implementing any Sale or retransfer of the
Stations' Assets relating to one, some or all of the Stations. Existing
programming contracts between the Stations and Clear Channel or any affiliate of
Clear Channel for programming broadcast by the Stations may continue in force
until their termination or may be renewed if renewal on the same terms is
automatic upon notification. Ministerial written communications in connection
with existing contracts may continue.

          (d) Any communications permitted by Section 6(a), 6(b) or 6(c) shall
be evidenced in writing, and shall be retained by the Trustee for inspection
upon request by the FCC.

          (e) All notices and other communications given under this Trust
Agreement shall be deemed to have been duly given when delivered in person or by
overnight express, mailed by first-class, registered or certified mail, postage
prepaid, or transmitted by facsimile and addressed to the parties as follows:

     7. Miscellaneous

          (a) This Trust Agreement, together with the Engagement Agreement,
constitute the entire agreement between the parties hereto and thereto with
respect to the subject

                                      -11-

matter hereof and thereof and supersede all prior oral or other written
agreements, commitments or understandings with respect to the matters provided
for herein and therein. This Trust Agreement shall not be amended, altered or
modified except by an instrument in writing duly executed by each of the parties
hereto. Substantial changes in this Trust Agreement may be made only as required
or approved by FCC order. A copy of any insubstantial change shall be filed by
the Trustee with the FCC within ten days following the execution thereof, with
copies to the appropriate divisions and bureaus of the FCC.

          (b) This Trust Agreement shall be binding upon and shall inure to the
benefit of the parties hereto and their respective permitted successors and
permitted assigns. Subject to Section 4(g) hereof, this Trust Agreement shall
not be assignable by either party, provided, however, that Clear Channel may
freely assign its rights and obligations hereunder without Trustee's prior
written consent to any person or entity that owns or controls, is owned or
controlled by, or is under common control with, Clear Channel.

          (c) If any part of any provision of this Trust Agreement or any other
agreement, document or writing given pursuant to or in connection with this
Trust Agreement shall be invalid or unenforceable under applicable law, said
part shall be ineffective to the extent of such invalidity only, without in any
way affecting the remaining part of said provision or the remaining provisions
of this Trust Agreement.

          (d) The headings of the sections of this Trust Agreement are inserted
for convenience of reference only and do not form a part or affect the meaning
hereof.

          (e) This Trust Agreement, the rights and obligations of the parties
hereto, and any claims and disputes relating thereto, shall be governed by and
construed in accordance with the laws of the State of Delaware (not including
the choice of law rules thereof).

          (f) This Trust Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, and all of which
together shall be deemed to be one and the same instrument.

          (g) It is the intention of the parties hereto that the CCU/AMFM Trust
I shall be disregarded as an entity separate from Clear Channel and the Subs for
federal income tax purposes, and that all of its assets shall be treated for tax
purposes as directly owned by Clear Channel or one of the Subs, as appropriate,
and any successor thereto by merger or otherwise. The parties hereto agree that
all relevant federal income tax reporting shall be consistent with the
foregoing.

     8. Compliance With Consent Decree. Notwithstanding any other provision of
this Trust Agreement, the Trustee and all other parties hereto agree to comply
with the terms of any consent decree entered into by Clear Channel and/or AMFM
with DOJ (a "Consent Decree"), including, without limitation, divestiture of one
or more Stations within any period of time and in the manner specified therein.
Should any term, provision or condition of this Trust Agreement conflict in any
respect with any term, provision or condition of a Consent Decree, the Consent
Decree shall be controlling.

          SECTION 3.1 REPRESENTATION AND WARRANTIES OF THE COMPANY. The Company
hereby makes the following representations and warranties to the Purchaser:

          (a) ORGANIZATION, GOOD STANDING AND POWER. The Company is a
corporation duly incorporated, validly existing and in good standing under the
laws of Delaware and has the requisite corporate power to own, lease and operate
its properties and assets and to conduct its business as it is now being
conducted. As of the date hereof, the Company does not have any subsidiaries (as
defined in Section 3.1(g)) except as set forth in the Registration Statement and
in the Company's most recent Form 10-K, including the accompanying financial
statements (the "FORM 10-K"), or in the Company's most recent Form 10-Q (the
"FORM 10-Q"), or on SCHEDULE 3.1(a) attached hereto. The Company and each such
subsidiary is duly qualified as a foreign corporation to do business and is in
good standing in every jurisdiction in which the nature of the

                                      -3-
<PAGE>   7

business conducted or property owned by it makes such qualification necessary
except for any jurisdiction in which the failure to be so qualified will not
have a Material Adverse Effect.

          (b) AUTHORIZATION; ENFORCEMENT. The Company has the requisite
corporate power and authority to enter into and perform this Agreement and to
issue and sell the Shares in accordance with the terms hereof. The execution,
delivery and performance of this Agreement by the Company and the consummation
by it of the transactions contemplated hereby have been duly and validly
authorized by all necessary corporate action, and, except as contemplated by
Section 4.4(b), no further consent or authorization of the Company or its Board
of Directors or stockholders is required. This Agreement has been duly executed
and delivered by the Company. This Agreement constitutes, or shall constitute
when executed and delivered, a valid and binding obligation of the Company
enforceable against the Company in accordance with its terms, except as such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation, conservatorship, receivership or
similar laws relating to, or affecting generally the enforcement of, creditor's
rights and remedies or by other equitable principles of general application.

          (c) CAPITALIZATION. The authorized capital stock of the Company and
the shares thereof issued and outstanding as of August 7, 2000 are set forth on
SCHEDULE 3.1(c) attached hereto. All of the outstanding shares of the Company's
Common Stock have been duly and validly authorized, and are fully paid and
non-assessable. Except as set forth in this Agreement including SCHEDULE 3.1(c),
as of August 7, 2000 no shares of Common Stock are entitled to preemptive rights
or registration rights and there are no outstanding options, warrants, scrip,
rights to subscribe to, call or commitments of any character whatsoever relating
to, or securities or rights convertible into, any shares of capital stock of the
Company. Furthermore, except as set forth in this Agreement including SCHEDULE

understandings, or arrangements by which the Company is or may become bound to
issue additional shares of the capital stock of the Company or options,
securities or rights convertible into shares of capital stock of the Company.
Except for customary transfer restrictions contained in agreements entered into
by the Company in order to sell restricted securities or as set forth in
SCHEDULE 3.1(c), as of August 7, 2000, the Company is not a party to any
agreement granting registration rights to any person with respect to any of its
equity or debt securities. The Company is not a party to, and it has no
knowledge of, any agreement restricting the voting or transfer of any shares of
the capital stock of the Company. The offer and sale of all capital stock,
convertible securities, rights, warrants, or options of the Company issued prior
to the Closing complied with all applicable federal and state securities laws,
and no stockholder has a right of rescission or damages with respect thereto
which would have a Material Adverse Effect. The Company has furnished or made
available to the Purchaser true and correct copies of the Company's Amended and
Restated Certificate of Incorporation, as amended to date and in effect on the
date hereof (the "CHARTER"), and the Company's Amended and Restated Bylaws as in
effect on the date hereof (the "BYLAWS").

          (d) ISSUANCE OF SHARES. The Shares to be issued under this Agreement
have been duly authorized by all necessary corporate action and, when paid for
and issued in accordance with the terms hereof, the Shares shall be validly
issued and outstanding, fully paid and non-assessable, and the Purchaser shall
be entitled to all rights accorded to a holder of Common Stock.

<PAGE>   8

          (e) NO CONFLICTS. The execution, delivery and performance of this
Agreement by the Company and the consummation by the Company of the transactions
contemplated herein do not (i) violate any provision of the Company's Charter or
Bylaws, (ii) conflict with, or constitute a default (or an event which with
notice or lapse of time or both would become a default) under, or give to others
any rights of termination, amendment, acceleration or cancellation of, any
material agreement, mortgage, deed of trust, indenture, note, bond, license,
lease agreement, instrument or obligation to which the Company is a party, (iii)
create or impose a lien, charge or encumbrance on any property of the Company
under any agreement or any commitment to which the Company is a party or by
which the Company is bound or by which any of its respective properties or
assets are bound, or (iv) result in a violation of any federal, state, local or
foreign statute, rule, regulation, order, judgment or decree (including federal
and state securities laws and regulations) applicable to the Company or any of
its subsidiaries or by which any property or asset of the Company or any of its
subsidiaries are bound or affected, except, in all cases, for such conflicts,
defaults, terminations, amendments, acceleration, cancellations and violations
as would not, individually or in the aggregate, have a Material Adverse Effect.
The Company is not required under federal, state or local law, rule or
regulation to obtain any consent, authorization or order of, or make any filing
or registration with, any court or governmental agency in order for it to
execute, deliver or perform any of its obligations under this Agreement, or
issue and sell the Shares in accordance with the terms hereof (other than any
filings which may be required to be made by the Company with the Commission, or
the Nasdaq National Market subsequent to the Closing, and, any registration
statement which may be filed pursuant hereto); provided that, for purpose of the
representation made in this sentence, the Company is assuming and relying upon
the accuracy of the relevant representations and agreements of the Purchaser
herein.

          (f) COMMISSION DOCUMENTS, FINANCIAL STATEMENTS. The Common Stock of
the Company is registered pursuant to Section 12(b) or 12(g) of the Securities
Exchange Act of 1934, as amended (the "EXCHANGE ACT"), and as of the date hereof
the Company has timely filed all reports, schedules, forms, statements and other
documents required to be filed by it with the Commission pursuant to the
reporting requirements of the Exchange Act, including material filed pursuant to
Section 13(a) or 15(d) of the Exchange Act (all of the foregoing including

"COMMISSION DOCUMENTS"). The Company has delivered or made available to the
Purchaser true and complete copies of the Commission Documents filed with the
Commission since December 31, 1999 and prior to the Closing Date. The Company
has not provided to the Purchaser any information which, according to applicable
law, rule or regulation, should have been disclosed publicly by the Company but
which has not been so disclosed, other than with respect to the transactions
contemplated by this Agreement. The Form 10-K for the year ended December 31,
1999 complied in all material respects with the requirements of the Exchange Act
and the rules and regulations of the Commission promulgated thereunder and other
federal, state and local laws, rules and regulations applicable to such
documents, and the said Form 10-K did not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading. The financial statements of the
Company included in the Commission Documents comply as to form in all material
respects with applicable accounting requirements and the published rules and
regulations of the Commission or other applicable rules and regulations with
respect thereto. Such financial statements have been prepared in

                                      -5-
<PAGE>   9

accordance with generally accepted accounting principles ("GAAP") applied on a
consistent basis during the periods involved (except (i) as may be otherwise
indicated in such financial statements or the notes thereto or (ii) in the case
of unaudited interim statements, to the extent they may not include footnotes or
may be condensed or summary statements), and fairly present in all material
respects the financial position of the Company and its subsidiaries as of the
dates thereof and the results of operations and cash flows for the periods then
ended (subject, in the case of unaudited statements, to normal year-end audit
adjustments).

          (g) SUBSIDIARIES. The Commission Documents or SCHEDULE 3.1(g) attached
hereto set forth each subsidiary of the Company as of the date hereof, showing
the jurisdiction of its incorporation or organization and showing the percentage
of each person's ownership of the outstanding stock or other interests of such
subsidiary. For the purposes of this Agreement, "subsidiary" shall mean any
corporation or other entity of which at least a majority of the securities or
other ownership interest having ordinary voting power (absolutely or
contingently) for the election of directors or other persons performing similar
functions are at the time owned directly or indirectly by the Company and/or any
of its other subsidiaries. Except as set forth in the Commission Documents or
the Commission Filings, none of such subsidiaries is a "significant subsidiary"
as defined in Regulation S-X.

          (h) NO MATERIAL ADVERSE EFFECT. Since June 30, 2000, the Company has
not experienced or suffered any Material Adverse Effect except continued losses
from operations.

          (i) NO UNDISCLOSED LIABILITIES. The Company has no liabilities,
obligations, claims or losses (whether liquidated or unliquidated, secured or
unsecured, absolute, accrued, contingent or otherwise) that would be required to
be disclosed on a balance sheet of the Company or any subsidiary (including the
notes thereto) in conformity with GAAP not disclosed in the Commission
Documents, other than those incurred in the ordinary course of the Company's or
its subsidiaries respective businesses since December 31, 1999 and which,
individually or in the aggregate, do not or would not have a Material Adverse
Effect.

          (j) NO UNDISCLOSED EVENTS OR CIRCUMSTANCES. No event or circumstance
has occurred or exists with respect to the Company or its subsidiaries or their
respective businesses, properties, prospects, operations or financial condition,
which, under applicable law, rule or regulation, requires public disclosure or
announcement by the Company but which has not been so publicly announced or
disclosed and which, individually or in the aggregate, do not or would not have
a Material Adverse Effect.

          (k) INDEBTEDNESS. SCHEDULE 3.1(k) sets forth as of June 30, 2000 all
outstanding secured and unsecured Indebtedness of the Company, or for which the
Company or any subsidiary has commitments. For the purposes of this Agreement,
"Indebtedness" shall mean (a) any liabilities for borrowed money or amounts owed
in excess of $100,000 (other than trade accounts payable incurred in the
ordinary course of business), (b) all guaranties, endorsements and other
contingent obligations in respect of Indebtedness of others, whether or not the
same are or should be reflected in the Company's balance sheet (or the notes
thereto), except guaranties by endorsement of negotiable instruments for deposit
or collection or similar transactions in the ordinary course of business; and
(c) the present value of any lease payments in excess of

                                      -6-
<PAGE>   10
$100,000 due under leases required to be capitalized in accordance with GAAP.
Neither the Company or any subsidiary is in default with respect to any
Indebtedness.

          (l) TITLE TO ASSETS. Each of the Company and its subsidiary has good
and marketable title to all of its real and personal property reflected in the
Commission Documents, free of any mortgages, pledges, charges, liens, security
interests or other encumbrances, except for those indicated in the Commission
Documents and the Commission Filings or such that could not reasonably be
expected to cause a Material Adverse Effect. All said leases of the Company and
each of its subsidiaries are valid and subsisting and in full force and effect
in all material respects.

          (m) ACTIONS PENDING. There is no action, suit, claim, investigation or
proceeding pending or, to the knowledge of the Company, threatened against the
Company which questions the validity of this Agreement or the transactions
contemplated hereby or any action taken or to be taken pursuant hereto or
thereto. There is no action, suit, claim, investigation or proceeding pending
or, to the knowledge of the Company, threatened, against or involving the
Company or any subsidiary, or any of their respective properties or assets
which, if adversely determined, is reasonably likely to result in a Material
Adverse Effect.

          (n) COMPLIANCE WITH LAW. The business of the Company has been and is
presently being conducted in accordance with all applicable federal, state and
local governmental laws, rules, regulations and ordinances, except as such that
do not cause a Material Adverse Effect. Each of the Company and its subsidiary
has all franchises, permits, licenses, consents and other governmental or
regulatory authorizations and approvals necessary for the conduct of its
business as now being conducted unless the failure to possess such franchises,
permits, licenses, consents and other governmental or regulatory authorizations
and approvals, individually or in the aggregate, could not reasonably be
expected to have a Material Adverse Effect.

          (o) CERTAIN FEES. No brokers, finders or financial advisory fees or
commissions will be payable by the Company with respect to the transactions
contemplated by this Agreement.

          (p) DISCLOSURE. To the best of the Company's knowledge, neither this
Agreement or the Schedules hereto nor any other documents, certificates or
instruments furnished to the Purchaser by or on behalf of the Company in
connection with the transactions contemplated by this Agreement contain any
untrue statement of a material fact or omits to state a material fact necessary
in order to make the statements made herein or therein, in the light of the
circumstances under which they were made herein or therein, not misleading.

          (q) OPERATION OF BUSINESS. The Company or its subsidiary owns or has a
valid right to use all patents, trademarks, service marks, trade names,
copyrights, licenses and authorizations, which are necessary for the conduct of
its business as now conducted without any conflict with the rights of others,
except to the extent set forth in the Commission Documents or that a Material
Adverse Effect could not reasonably be expected to result from such conflict.

                                      -7-
<PAGE>   11

          (r) ENVIRONMENTAL COMPLIANCE. Except as disclosed in the Commission
Filings, the Company has obtained all material approvals, authorization,
certificates, consents, licenses, orders and permits or other similar
authorizations of all governmental authorities, or from any other person, that
are required under any Environmental Laws. "Environmental Laws" shall mean all
applicable laws relating to the protection of the environment including, without
limitation, all requirements pertaining to reporting, licensing, permitting,
controlling, investigating or remediating emissions, discharges, releases or
threatened releases of hazardous substances, chemical substances, pollutants,
contaminants or toxic substances, materials or wastes, whether solid, liquid or
gaseous in nature, into the air, surface water, groundwater or land, or relating
to the manufacture, processing, distribution, use, treatment, storage, disposal,
transport or handling of hazardous substances, chemical substances, pollutants,
contaminants or toxic substances, material or wastes, whether solid, liquid or
gaseous in nature. Except for such instances as would not individually or in the
aggregate have a Material Adverse Effect, to the best of the Company's
knowledge, there are no past or present events, conditions, circumstances,
incidents, actions or omissions relating to or in any way affecting the Company
that violate or could reasonably be expected to violate any Environmental Law
after the Closing or that could reasonably be expected to give rise to any
environmental liability, or otherwise form the basis of any claim, action,
demand, suit, proceeding, hearing, study or investigation (i) under any
Environmental Law, or (ii) based on or related to the manufacture, processing,
distribution, use, treatment, storage (including without limitation underground
storage tanks), disposal, transport or handling, or the emission, discharge,
release or threatened release of any hazardous substance.

          (s) MATERIAL AGREEMENTS. Except as set forth in the Commission
Documents and this Agreement, the Company is not a party to any written or oral
contract, instrument, agreement, commitment, obligation, plan or arrangement, a
copy of which would be required to be filed with the Commission as an exhibit to
a registration statement on Form S-3 or applicable form (collectively, "MATERIAL
AGREEMENTS") if the Company was registering securities under the Securities Act.
The Company has in all material respects performed all the obligations required
to be performed to date under the foregoing agreements, has received no notice
of default and, to the best of the Company's knowledge is not in default under
any Material Agreement now in effect, the result of which could reasonably be
expected to cause a Material Adverse Effect.

          (t) TRANSACTIONS WITH AFFILIATES. Except as set forth in SCHEDULE
3.1(t) hereto there are no loans, leases, agreements, contracts, royalty
agreements, management contracts or arrangements or other continuing
transactions exceeding $100,000 between (a) the Company, or any of its customers
(excluding agreements related to the purchase or lease of the Company's
products) or suppliers on the one hand, and (b) on the other hand, any officer,
employee, consultant or director of the Company, or any person who would be
covered by Item 404(a) of Regulation S-K or any corporation or other entity
controlled by such officer, employee, consultant, director or person.

          (u) SECURITIES ACT OF 1933. The Company has complied in all material
respects with all applicable federal and state securities laws in connection
with the offer, issuance and sale of the Shares hereunder.

               (i) Each Prospectus included as part of the Registration
Statement as originally filed or as part of any amendment or supplement thereto,
or filed pursuant to Rule 424

                                      -8-
<PAGE>   12

under the Securities Act, complied when so filed in all material respects with
the provisions of the Securities Act. The Commission has not issued any order
preventing or suspending the use of any Prospectus.

               (ii) The Company meets the requirements for the use of Form S-3
under the Securities Act. The Registration Statement in the form in which it
became effective and also in such form as it may be when any post-effective
amendment thereto became effective and the Prospectus and any supplement or
amendment thereto when filed with the Commission under Rule 424(b) under the
Securities Act, complied in all material respects with the provisions of the
Securities Act and did not at any such times contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein (in the case of the Prospectus, in the
light of the circumstances under which they made) not misleading, except that
this representation and warranty does not apply to statements in or omissions
from the Registration Statement or the Prospectus made in reliance upon and in
conformity with information relating to the Purchaser furnished to the Company
in writing by or on behalf of the Purchaser through you expressly for use
therein.

               (iii) The Company has not distributed and, prior to the
completion of the sale of the Shares to the Purchaser, will not distribute any
offering material in connection with the offering and sale of the Shares other
than the Registration Statement, the Prospectus or other materials, if any,
permitted by the Securities Act.

          (v) EMPLOYEES. As of the date hereof, the Company has no collective
bargaining arrangements or agreements covering any of its employees. Except as
set forth on SCHEDULE 3.1(v) attached hereto, as of the date hereof the Company
has no employment contract or any other similar contract or restrictive
covenant, relating to the right of any officer, employee or consultant to be
employed or engaged by the Company. As of the date hereof, since December 31,
1998, no officer, consultant or key employee of the Company whose termination,
either individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect, has terminated or, to the knowledge of the Company, has
any present intention of terminating his or her employment or engagement with
the Company.

          (w) USE OF PROCEEDS. The proceeds from the sale of the Shares will be
used by the Company and its subsidiary for general corporate purposes.

          (x) PUBLIC UTILITY HOLDING COMPANY ACT AND INVESTMENT COMPANY ACT
STATUS. The Company is not a "holding company" or a "public utility company" as
such terms are defined in the Public Utility Holding Company Act of 1935, as
amended. The Company is not, and as a result of and immediately upon Closing
will not be, an "investment company" or a company "controlled" by an "investment
company," within the meaning of the Investment Company Act of 1940, as amended.

          (y) ERISA. No liability to the Pension Benefit Guaranty Corporation
has been incurred with respect to any Plan by the Company which is or would have
a Material Adverse Effect. The execution and delivery of this Agreement and the
issue and sale of the Shares will not involve any transaction which is subject
to the prohibitions of Section 406 of ERISA or in connection with which a tax
could be imposed pursuant to Section 4975 of the Internal Revenue

                                      -9-
<PAGE>   13

Code of 1986, as amended, provided that, if any of the Purchaser, or any person
or entity that owns a beneficial interest in any of the Purchaser, is an
"employee pension benefit plan" (within the meaning of Section 3(2) of ERISA)
with respect to which the Company is a "party in interest" (within the meaning
of Section 3(14) of ERISA), the requirements of Sections 407(d)(5) and 408(e) of
ERISA, if applicable, are met. As used in this Section 3.1(y), the term "Plan"
shall mean an "employee pension benefit plan" (as defined in Section 3 of ERISA)
which is or has been established or maintained, or to which contributions are or
have been made, by the Company or by any trade or business, whether or not
incorporated, which, together with the Company, is under common control, as
described in Section 414(b) or (c) of the Code.

          (z) ACKNOWLEDGMENT REGARDING PURCHASER'S PURCHASE OF SHARES. The
Company acknowledges and agrees that the Purchaser is acting solely in the
capacity of arm's length purchaser with respect to this Agreement and the
transactions contemplated hereunder. The Company further acknowledges that the
Purchaser is not acting as a financial advisor or fiduciary of the Company (or
in any similar capacity) with respect to this Agreement and the transactions
contemplated hereunder and any advice given by the Purchaser or any of its
representatives or agents in connection with this Agreement and the transactions
contemplated hereunder is merely incidental to the Purchaser's purchase of the
Shares.

          SECTION 3.2 REPRESENTATION AND WARRANTIES OF THE PURCHASER. The
Purchaser hereby makes the following representations and warranties to the
Company:

          (a) ORGANIZATION AND STANDING OF THE PURCHASER. The Purchaser is a
limited liability company duly organized, validly existing and in good standing
under the laws of the Commonwealth of the Bahamas.

          (b) AUTHORIZATION AND POWER. The Purchaser has the requisite corporate
power and authority to enter into and perform this Agreement and to purchase the
Shares in accordance with the terms hereof. The execution, delivery and
performance of this Agreement by Purchaser and the consummation by it of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action, and no further consent or authorization of the Purchaser, its
Board of Directors or stockholders is required. This Agreement constitutes, or
shall constitute when executed and delivered, a valid and binding obligation of
the Purchaser enforceable against the Purchaser in accordance with its terms,
except as such enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium, liquidation, conservatorship,
receivership, or similar laws relating to, or affecting generally the
enforcement of, creditor's rights and remedies or by other equitable principles
of general application.

          (c) NO CONFLICTS. The execution, delivery and performance of this
Agreement and the consummation by the Purchaser of the transactions contemplated
hereby and thereby or relating hereto do not and will not (i) result in a
violation of such Purchaser's charter documents or bylaws or (ii) conflict with,
or constitute a default (or an event which with notice or lapse of time or both
would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation of any material agreement, mortgage,
deed of trust, indenture, note, bond, license, lease agreement, instrument or
obligation to which the Purchaser is a party, (iii) create or impose or lien,
charge or encumbrance on any property of the Purchaser under any agreement or
any commitment to which the Purchaser is party or by which the

                                      -10-
<PAGE>   14

Purchaser is on or by which any of its respective properties or assets are bound
or (iv) result in a violation of any law, rule, or regulation, or any order,
judgment or decree of any court or governmental agency applicable to the
Purchaser or its properties, except for such conflicts, defaults and violations
as would not, individually or in the aggregate, prohibit or otherwise interfere
with the ability of the Purchaser to enter into and perform its obligations
under this Agreement in any material respect. The Purchaser is not required to
obtain any consent, authorization or order of, or make any filing or
registration with, any court or governmental agency in order for it to execute,
deliver or perform any of its obligations under this Agreement or to purchase
the Shares in accordance with the terms hereof, provided that for purposes of
the representation made in this sentence, the Purchaser is assuming and relying
upon the accuracy of the relevant representations and agreements of the Company
herein.

          (d) INFORMATION. The Purchaser and its advisors, if any, have been
furnished with all materials relating to the business, finances and operations
of the Company and materials relating to the offer and sale of the Shares which
have been requested by the Purchaser. The Purchaser and its advisors, if any,
have been afforded the opportunity to ask questions of the Company. The
Purchaser has sought such accounting, legal and tax advice as it has considered
necessary to make an informed investment decision with respect to its
acquisition of the Shares. Purchaser understands that it (and not the Company)
shall be responsible for its own tax liabilities that may arise as a result of

will comply in all respects with the Company's reporting, filing and other
obligations under the bylaws or rules of the Nasdaq National Market.

          SECTION 4.3 REGISTRATION STATEMENT. Before the Company shall issue a

Common Stock to be authorized and registered to cover the Shares to be issued in
connection with this Agreement.

          SECTION 4.4 COMPLIANCE WITH LAWS.

          (a) The Company shall comply with all applicable laws, rules,
regulations and orders, noncompliance with which could have a Material Adverse
Effect.

          (b) The Company will not be obligated to issue and the Purchaser will

would result in the issuance under this Agreement of more than nineteen and
nine-tenths percent (19.9%) of the issued and outstanding shares of the
Company's Common Stock.

          SECTION 4.5 KEEPING OF RECORDS AND BOOKS OF ACCOUNT. The Company shall
keep adequate records and books of account, in which complete entries will be

<PAGE>   16

          SECTION 4.8 EFFECTIVE REGISTRATION STATEMENT. If, at the time this
Agreement is executed and delivered, it is necessary for the Registration
Statement or a post-effective amendment thereto to be declared effective before
the offering of the Shares may commence, the Company will endeavor to cause the
Registration Statement or such post-effective amendment to become effective as
soon as reasonably practicable and will advise the Purchaser promptly and, if
requested by the Purchaser, will confirm such advice in writing, when it
receives notice that the Registration Statement or such post-effective amendment
has become effective.

          SECTION 4.9 NO STOP ORDERS. The Company will advise the Purchaser
promptly and, if requested by the Purchaser, will confirm such advice in
writing: (i) of its receipt of notice of any request by the Commission for
amendment of or a supplement to the Registration Statement, any Prospectus or
for additional information; (ii) of its receipt of notice of the issuance by the
Commission of any stop order suspending the effectiveness of the Registration
Statement or of the suspension of qualification of the Shares for offering or
sale in any jurisdiction or the initiation of any proceeding for such purpose;
and (iii) of its becoming aware of the happening of any event, which makes any
statement of a material fact made in the Registration Statement or the
Prospectus (as then amended or supplemented) untrue or which requires the making
of any additions to or changes in the Registration Statement or the Prospectus
(as then amended or supplemented) in order to state a material fact required by
the Securities Act or the regulations thereunder to be stated therein or
necessary in order to make the statements therein not misleading, or of the
necessity to amend or supplement the Prospectus (as then amended or
supplemented) to comply with the Securities Act or any other law. If at any time
the Commission shall issue any stop order suspending the effectiveness of the
Registration Statement, the Company will make commercially reasonable efforts to
obtain the withdrawal of such order at the earliest possible time.

          SECTION 4.10 AMENDMENTS TO THE REGISTRATION STATEMENT. The Company
will not (i) file any amendment to the Registration Statement or make any
amendment or supplement to the Prospectus of which the Purchaser shall not
previously have been advised or to which the Purchaser shall reasonably object
after being so advised or (ii) so long as, in the reasonable opinion of counsel
for the Purchaser, a Prospectus is required to be delivered in connection with
sales by any Purchaser or dealer, file any information, documents or reports
pursuant to the Exchange Act without delivering a copy of such information,
documents or reports to the Purchaser, promptly following such filing.

          SECTION 4.11 PROSPECTUS DELIVERY. The Company shall file a prospectus
supplement to its Registration Statement on the first business day immediately
following the end of each Draw Down Pricing Period, and will deliver to the
Purchaser, without charge, in such quantities as reasonably requested by the
Purchaser, copies of each form of Prospectus and prospectus supplement on each
Settlement Date. The Company consents to the use of the Prospectus (and of any
amendment or supplement thereto) in accordance with the provisions of the
Securities Act and with the securities or Blue Sky laws of the jurisdictions in
which the Shares may be sold by the Purchaser, in connection with the offering
and sale of the Shares and for such period of time thereafter as the Prospectus
is required by the Securities Act to be delivered in connection with sales of
the Shares. If during such period of time any event shall occur that in the
judgment of the Company or in the opinion of counsel for the Purchaser is

                                      -13-
<PAGE>   17

required to be set forth in the Prospectus (as then amended or supplemented) or
should be set forth therein in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading, or if it
is necessary to supplement or amend the Prospectus to comply with the Securities
Act or any other law, the Company will forthwith prepare and, subject to the
provisions of Section 4.10 above, file with the Commission an appropriate
supplement or amendment thereto, and will expeditiously furnish to the Purchaser
a reasonable number of copies thereof.

          SECTION 4.12 OTHER FINANCING. Except for issuances under outstanding
obligations disclosed in SCHEDULE 3.1(c) attached hereto, the Company is
restricted from entering into any other financing agreement during the
Investment Period, the primary purpose of which would be to obtain equity
financing for the Company (an "OTHER FINANCING"), without the prior written
consent of the Purchaser, which consent will not be unreasonably withheld,
conditioned or delayed, except that the Company may (i) enter into a loan,
credit or lease facility with a bank or financing institution (including any
equity component thereof), (ii) establish an employee stock option plan or
agreement or finance the acquisition of other companies, equipment, technologies
or lines of business, (iii) issue shares of Common Stock in connection with the
Company's current option plans (as the same may be amended from time to time),
stock purchase plans, rights plans, currently outstanding warrants or options,
or increase the number of shares available under any such plans (the primary
purpose of which is not to raise equity), and (iv) issue shares of Common Stock
and/or Preferred Stock in connection with the formation and maintenance of
strategic partnerships, alliances or joint ventures and the acquisition of
products, licenses or other assets (each a "Permitted Transaction"). Within two
(2) trading days of receipt of notice of an Other Financing, together with the
terms of the Other Financing, the Purchaser will notify the Company as to
whether it consents to the Other Financing. If the Purchaser consents to the
Company entering into an Other Financing and the Company enters into an Other
Financing during a Draw Down Pricing Period, the Purchaser shall have the
options set forth in Section 6.1(k) hereof. If the Purchaser consents to the
Company entering into an Other Financing and the Company enters into the Other
Financing between Draw Down Pricing Periods, the Purchaser shall have the
option, which option shall be exercised no later than five (5) trading days
after receipt by the Purchaser of the notice of the Other Financing, to purchase
up to the Draw Down Amount that would be applicable under this Agreement based
on the price per share to be paid for the Common Stock in the Other Financing on
the same, absolute terms and conditions contemplated in the Other Financing. If
the Purchaser does not exercise its purchase option in writing before 8:00 p.m.
(eastern time), the Company shall have the right to close the Other Financing on
the scheduled closing date with a third party, PROVIDED that all of the terms
and conditions of such closing are similar in all material respects to those
provided to the Purchaser prior to the Purchaser giving its consent to such
Other Financing.

          SECTION 4.13 NOTICE. The Company shall immediately notify the
Purchaser that (i) a Material Adverse Effect has occurred or (ii) the Company
has entered into an Other Financing (as defined in Section 4.12 hereof).

                                   ARTICLE VI

                          DRAW DOWN TERMS; CALL OPTION

          SECTION 6.1 DRAW DOWN TERMS. Subject to the satisfaction of the
conditions set forth in this Agreement, the parties agree as follows:

          (a) The Company, may, in its sole discretion, issue a Draw Down Notice
with respect to a draw down (a "DRAW DOWN") during each Draw Down Pricing Period
of up to $2,500,000 if the Threshold Price is equal to $5.00 and up to and
additional $500,000 for every $1.00 increase in the Threshold Price above $5.00
up to and including $20.00 for a maximum Draw Down Amount during each Draw Down
Pricing Period of up to $10,000,000; PROVIDED, HOWEVER, that for every $1.00
decrease in the Threshold Price below $5.00, down to a minimum Threshold Price
of $3.00, the Draw Down shall be decreased by $500,000, incrementally; PROVIDED,
FURTHER, that the Company may, in its sole discretion, issue a Draw Down Notice
with respect to any Draw Down Amount at any Threshold Price or any Draw Down
Discount Percentage pursuant to terms mutually agreed upon by the Purchaser and
the Company, which Draw Down the Purchaser will be obligated to accept. Prior to
issuing any Draw Down Notice, the Company shall have Shares registered under the
Registration Statement which are valued at an amount equal to or in excess of
the Draw Down Amount.

          (b) The number of Shares to be issued in connection with each Draw
Down shall be equal to the sum of the quotients (for each trading day of the
Draw Down Pricing Period for which the VWAP equals or exceeds the Threshold
Price) of (x) 1/20th (or such other fraction based on the length of the Draw
Down Pricing Period) of the Draw Down Amount divided by (y) the applicable Draw
Down Discount Percentage multiplied by the VWAP of the Common Stock for such
trading day.

          (c) Only one Draw Down shall be allowed in each Draw Down Pricing
Period. Each Draw Down Pricing Period shall consist of two (2) periods of ten
(10) consecutive trading days (each, a "SETTLEMENT PERIOD").

          (d) The number of Shares purchased by the Purchaser with respect to
each Draw Down shall be determined on a daily basis during each Draw Down
Pricing Period and settled on the second business day following the end of each
Settlement Period (the "SETTLEMENT DATE").

          (e) There shall be a minimum of five (5) trading days between Draw
Downs, unless otherwise mutually agreed upon between the Purchaser and the
Company.

          (f) There shall be a maximum of twelve (12) monthly Draw Downs during
the term of this Agreement.

          (g) Each Draw Down will expire on the end of the last trading day of
each Draw Down Pricing Period.

          (h) If the VWAP on a given trading day is less than the Threshold
Price, then the total amount of the Draw Down for the relevant Draw Down Pricing
Period will be reduced by

                                      -18-
<PAGE>   22

1/20th (or such other fraction based on the length of the Draw Down Pricing
Period). Notwithstanding anything in the foregoing to the contrary, for each
trading day during the Draw Down Pricing Period that the VWAP is less than the
Threshold Price, the Purchaser may elect in its sole discretion to purchase
Shares at a price equal to the Threshold Price multiplied by the Draw Down
Discount Percentage at the end of such Draw Down Pricing Period. At no time
shall the Threshold Price be set below $3.00, unless mutually agreed upon by the
Company and the Purchaser. If trading in the Company's Common Stock is suspended
for any reason for more than three (3) hours in any trading day, at the
Purchaser's option, the price of the Common Stock shall be deemed to be below
the Threshold Price for that trading day and the Draw Down for the relevant Draw
Down Pricing Period shall be reduced by 1/20th (or such other fraction based on
the length of the Draw Down Pricing Period).

          (i) The Company must inform the Purchaser via facsimile transmission
as to the Draw Down Amount the Company wishes to exercise before commencement of
trading on the first trading day of the Draw Down Pricing Period (the "DRAW DOWN
NOTICE"), substantially in the form attached hereto as Exhibit C. In addition to
the Draw Down Amount, the Company shall set the Threshold Price with each Draw
Down Notice and shall designate the first trading day of the Draw Down Pricing
Period.

          (j) On each Settlement Date, the Company shall deliver the Shares
purchased by the Purchaser to the Purchaser or to The Depositary Trust Company
("DTC") on the Purchaser's behalf via the Deposit Withdrawal Agent Commission
system ("DWAC"), and upon receipt of the Shares, the Purchaser shall cause
payment therefor to be made to the account designated by the Company by wire
transfer of immediately available funds provided that the Shares are received no
later than 1:00 p.m., eastern time, or next day available funds if the Shares
are received thereafter.

          (k) If during any Draw Down Pricing Period the Company shall enter
into an Other Financing (other than shares of Common Stock issued under this
Agreement or in connection with a Permitted Transaction), the Purchaser may in
its sole discretion (i) purchase up to the Draw Down Amount of shares of Common
Stock and/or exercise Call Options granted during such Draw Down Pricing Period
on the terms at which the Company issued shares of Common Stock in the Other
Financing during such Draw Down Pricing Period, (ii) purchase up to the Draw
Down Amount of shares of Common Stock and/or exercise Call Options granted
during such Draw Down Pricing Period at the applicable Draw Down Discount
Percentage times the VWAP for such Draw Down Pricing Period, or (iii) elect not
to purchase any Shares during such Draw Down Pricing Period. The Purchaser shall
notify the Company of its election on the business day preceding the Settlement
Date.

          (l) If on the Settlement Date, the Company fails to deliver the Shares
to be purchased by the Purchaser, and such failure continues for ten (10)
trading days, the Company shall pay, in cash or restricted shares of Common
Stock, at the option of the Purchaser, as liquidated damages and not as a
penalty to the Purchaser an amount equal to two percent (2%) of the Draw Down
Amount for the initial thirty (30) days and each additional thirty (30) day
period thereafter until such failure has been cured, which shall be pro rated
for such periods less than thirty (30) days (the "PERIODIC AMOUNT"). Cash
payments to be made pursuant to this clause (1) shall be due and payable
immediately upon demand in immediately available cash funds.

                                      -19-
<PAGE>   23

Certificates evidencing the restricted shares of Common Stock shall be delivered
immediately upon demand. The parties agree that the Periodic Amount represents a
reasonable estimate on the part of the parties, as of the date of this
Agreement, of the amount of damages that may be incurred by the Purchaser if the
Company fails to deliver the Shares on the Settlement Date. If the Purchaser
elects to receive shares of Common Stock instead of cash, the Purchaser shall
have the right to demand registration once within twelve (12) months of the date
of issuance of such shares of Common Stock and piggyback registration rights if
the Company files a separate registration statement.

          SECTION 6.2 PURCHASER'S CALL OPTION.

          (a) During each Draw Down Pricing Period, the Company at its sole
discretion may grant to the Purchaser the right to exercise multiple call
options of up to the applicable Draw Down Amount (a "CALL OPTION"). The amount
of the Call Option shall be set forth in the Draw Down Notice. For each trading
day during a Draw Down Pricing Period, the Purchaser may exercise a Call Option
by providing notice to the Company of the exercise of a Call Option (the "CALL
OPTION NOTICE"), substantially in the form attached hereto as Exhibit D. The
total amount of Call Options exercised by the Purchaser shall not exceed
$30,000,000.

          (b) The number of shares of Common Stock to be issued in connection
with each Call Option shall equal the quotient of (i) the amount of the Call
Option exercised and (ii) the product of the applicable Draw Down Discount
Percentage and the greater of (A) the VWAP for the Common Stock on the day the
Purchaser issues its Call Option Notice and (B) the Threshold Price.

          (c) Each Call Option exercised shall be settled on the applicable
Settlement Date.

          (d) The Threshold Price designated by the Company in its Draw Down
Notice shall apply to each Call Option.

          (e) For each Call Option that the Purchaser exercises pursuant to this
Section 6.2, the Purchaser must issue via facsimile a Call Option Notice to the
Company no later than 8:00 p.m. (eastern time) on the day such Call Option is
exercised. If the Purchaser does not exercise a Call Option by 8:00 p.m.
(eastern time) on the last day of the applicable Draw Down Pricing Period, the
Purchaser's Call Options with respect to that Draw Down Pricing Period shall
terminate.

                                  ARTICLE VII

                                  TERMINATION

          SECTION 7.1 TERMINATION BY MUTUAL CONSENT. The term of this Agreement
shall be the earlier of (i) fourteen (14) months from the date of execution of
this Agreement (the "INVESTMENT PERIOD") and (ii) the date that all of the
Shares registered under the Registration Statement have been issued and sold to
and paid for by the Purchaser. This Agreement may be terminated at any time by

          SECTION 7.2 OTHER TERMINATION. The Company shall inform the Purchaser,
and the Purchaser shall have the right to terminate this Agreement within the
subsequent thirty (30) days (the "EVENT PERIOD"), if (x) the Company enters into
an Other Financing (excluding a Permitted Transaction) without the Purchaser's
prior consent which provides for (i) the issuance of Common Stock or securities
convertible, exercisable or exchangeable into Common Stock at a discount to the
then current market price of the Common Stock, (ii) a mechanism for the reset of
the purchase price of the Common Stock to below the then current market price of
the Common Stock, or (iii) the issuance of Common Stock with warrants, which
have an exercise price such that together with the price of the Common Stock
would result in the issuance of shares of Common Stock at a per share price
below the then current market price of the Common Stock, or (y) an event
resulting in a Material Adverse Effect has occurred. The Purchaser may terminate
this Agreement upon one (1) day's notice during the Event Period. The Company
may terminate this Agreement upon thirty (30) days' notice; PROVIDED, that such
termination does not occur during a Draw Down Pricing Period or prior to the
Settlement Date for such Draw Down Pricing Period and, if such termination
occurs prior to the tenth (10th) month anniversary of this Agreement and the
Company has not requested Draw Downs in an aggregate amount of $7,500,000, the
Company pays the fee to the Purchaser required under Section 9.1(b) hereof.

          SECTION 7.3 EFFECT OF TERMINATION. In the event of termination by the
Company or the Purchaser, written notice thereof shall forthwith be given to the
other party and the transactions contemplated by this Agreement shall be
terminated without further action by either party. If this Agreement is
terminated as provided in Section 7.1 or 7.2 herein, this Agreement shall become
void and of no further force and effect, except as provided in Section 9.9.
Nothing in this Section 7.3 shall be deemed to release the Company or the
Purchaser from any liability for any breach under this Agreement, or to impair
the rights of the Company and the Purchaser to compel specific performance by
the other party of its obligations under this Agreement.

                                  ARTICLE VIII

                                 INDEMNIFICATION

          SECTION 8.1 GENERAL INDEMNITY.

          (a) INDEMNIFICATION BY THE COMPANY. The Company will indemnify and
hold harmless the Purchaser and each person, if any, who controls the Purchaser
within the meaning of Section 15 of the Securities Act or Section 20(a) of the
Exchange Act from and against any losses, claims, damages, liabilities and
expenses (including reasonable costs of defense and investigation and all
attorney's fees) to which the Purchaser and each person, if any, who controls
the Purchaser may become subject, under the Securities Act or otherwise, insofar
as such losses, claims, damages, liabilities and expenses (or actions in respect
thereof) arise out of or are based upon, (i) any untrue statement or alleged
untrue statement of a material fact contained, or incorporated by reference, in
the Registration Statement relating to Common Stock being sold to the Purchaser
(including the any prospectus supplement filed in connection with the
transactions contemplated hereunder (the "PROSPECTUS SUPPLEMENT") which are a
part of it), or any amendment or supplement to it, or (ii) the omission or
alleged omission to state in that Registration Statement or any document
incorporated by reference in the Registration Statement,

                                      -21-
<PAGE>   25

a material fact required to be stated therein or necessary to make the
statements therein not misleading, PROVIDED that the Company shall not be liable
under this Section 8.1(a) to the extent that a court of competent jurisdiction
shall have determined by a final judgment that such loss, claim, damage,
liability or action resulted directly from any such acts or failures to act,
undertaken or omitted to be taken by the Purchaser or such person through its
bad faith or willful misconduct; PROVIDED, however, that the foregoing indemnity
shall not apply to any loss, claim, damage, liability or expense to the extent,
but only to the extent, arising out of or based upon any untrue statement or
alleged untrue statement or omission or alleged omission made in reliance upon
and in conformity with written information furnished to the Company by the
Purchaser expressly for use in the Registration Statement, any preliminary
prospectus or the Prospectus (or any amendment or supplement thereto); and
PROVIDED, further, that with respect to the Prospectus, the foregoing indemnity
shall not inure to the benefit of the Purchaser or any such person from whom the
person asserting any loss, claim, damage, liability or expense purchased Common
Stock, if copies of the Prospectus were timely delivered to the Purchaser
pursuant hereto and a copy of the Prospectus (as then amended or supplemented if
the Company shall have furnished any amendments or supplements thereto) was not
sent or given by or on behalf of the Purchaser or any such person to such
person, if required by law so to have been delivered, at or prior to the written
confirmation of the sale of the Common Stock to such person, and if the
Prospectus (as so amended or supplemented) would have cured the defect giving
rise to such loss, claim, damage, liability or expense.

          The Company will reimburse the Purchaser and each such controlling
person promptly upon demand for any legal or other costs or expenses reasonably
incurred by the Purchaser or any controlling person in investigating, defending
against, or preparing to defend against any such claim, action, suit or
proceeding, except that the Company will not be liable to the extent a claim or
action which results in a loss, claim, damage, liability or expense arises out
of, or is based upon, an untrue statement, alleged untrue statement, omission or
alleged omission, included in any Prospectus or Prospectus Supplement or any
amendment or supplement to the Prospectus or Prospectus Supplement in reliance
upon, and in conformity with, written information furnished by the Purchaser to
the Company for inclusion in the Prospectus or Prospectus Supplement.

          (b) INDEMNIFICATION BY THE PURCHASER. The Purchaser will indemnify and
hold harmless the Company, each of its directors and officers, and each person,
if any, who controls the Company within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act from and against any
expenses (including reasonable costs of defense and investigation and all
attorneys fees) to which the Company and each director, officer and person, if
any, who controls the Company may become subject, under the Securities Act or
otherwise, insofar as such losses, claims, damages, liabilities and expenses (or
actions in respect thereof) arise out of or are based upon, (i) any untrue
statement or alleged untrue statement of a material fact contained in any
Prospectus or Prospectus Supplement or any amendment or supplement to it or (ii)
the omission or alleged omission to state in any Prospectus or Prospectus
Supplement or any amendment or supplement to it a material fact required to be
stated therein or necessary to make the statements therein not misleading, to
the extent, but only to the extent, the untrue statement, alleged untrue
statement, omission or alleged omission was made in reliance upon, and in
conformity with, written information furnished by the Purchaser to the Company
for inclusion in the Prospectus or Prospectus Supplement or an amendment or
supplement to it, and

                                      -22-
<PAGE>   26

the Purchaser will reimburse the Company and each such director, officer or
controlling person promptly upon demand for any legal or other costs or expenses
reasonably incurred by the Company or the other person in investigating,
defending against, or preparing to defend against any such claim, action, suit
or proceeding.

          SECTION 8.2 INDEMNIFICATION PROCEDURES. Promptly after a person
receives notice of a claim or the commencement of an action for which the person
intends to seek indemnification under paragraph (a) or (b) of Section 8.1, the
person will notify the indemnifying party in writing of the claim or
commencement of the action, suit or proceeding, but failure to notify the
indemnifying party will not relieve the indemnifying party from liability under
paragraph (a) or (b) of Section 8.1, except to the extent it has been materially
prejudiced by the failure to give notice. The indemnifying party will be
entitled to participate in the defense of any claim, action, suit or proceeding
as to which indemnification is being sought, and if the indemnifying party
acknowledges in writing the obligation to indemnify the party against whom the
claim or action is brought, the indemnifying party may (but will not be required
to) assume the defense against the claim, action, suit or proceeding with
counsel satisfactory to it. After an indemnifying party notifies an indemnified
party that the indemnifying party wishes to assume the defense of a claim,
action, suit or proceeding the indemnifying party will not be liable for any
legal or other expenses incurred by the indemnified party in connection with the
defense against the claim, action, suit or proceeding except that if, in the
opinion of counsel to the indemnifying party, one or more of the indemnified
parties should be separately represented in connection with a claim, action,
suit or proceeding the indemnifying party will pay the reasonable fees and
expenses of one separate counsel for the indemnified parties. Each indemnified
party, as a condition to receiving indemnification as provided in Paragraph (a)
or (b) or Section 8.1, will cooperate in all reasonable respects with the
indemnifying party in the defense of any action or claim as to which
indemnification is sought. No indemnifying party will be liable for any
settlement of any action effected without its prior written consent. No
indemnifying party will, without the prior written consent of the indemnified
party, effect any settlement of a pending or threatened action with respect
which an indemnified party is, or is informed that it may be, made a party and
for which it would be entitled to indemnification, unless the settlement
includes an unconditional release of the indemnified party from all liability
and claims which are the subject matter of the pending or threatened action.

          If for any reason the indemnification provided for in this Agreement
is not available to, or is not sufficient to hold harmless, an indemnified party
in respect of any loss or liability referred to in paragraph (a) or (b) of
Section 8.1, each indemnifying party will, in lieu of indemnifying the
indemnified party, contribute to the amount paid or payable by the indemnified
party as a result of the loss or liability, (i) in the proportion which is
appropriate to reflect the relative benefits received by the indemnifying party
on the one hand and by the indemnified party on the other from the sale of stock
which is the subject of the claim, action, suit or proceeding which resulted in
the loss or liability or (ii) if that allocation is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits of the sale of stock, but also the relative fault of the indemnifying
party and the indemnified party with respect to the statements or omissions
which are the subject of the claim, action, suit or proceeding that resulted in
the loss or liability, as well as any other relevant equitable considerations.

                                   ARTICLE IX

                                  MISCELLANEOUS

          SECTION 9.1 FEES AND EXPENSES.

          (a) The Company shall pay all reasonable fees and expenses related to
the transactions contemplated by this Agreement; PROVIDED, that the Company
shall pay, at the Closing, all reasonable attorneys fees and expenses, inclusive
of disbursements and out-of-pocket expenses, incurred by the Purchaser of up to
$40,000 in connection with the preparation, negotiation, execution and delivery
of this Agreement. In addition, the Company shall pay all reasonable fees and
expenses incurred by the Purchaser in connection with any amendments,
modifications or waivers of this Agreement or incurred in connection with the
enforcement of this Agreement, including, without limitation, all reasonable
attorneys fees and expenses. The Company shall pay all stamp or other similar
taxes and duties levied in connection with issuance of the Shares pursuant
hereto.

          (b) If on the tenth (10th) month anniversary of this Agreement, the
Company has not requested Draw Downs in an aggregate amount of $7,500,000, the
Company shall pay the Purchaser, at the option of the Purchaser, a fee equal to
either (x) an amount equal to $225,000 in cash, or (ii) warrants to purchase
112,500 Shares at an exercise price of 110% of the VWAP of the Common Stock on
the date of execution of this Agreement. The Purchaser shall have the right to
demand registration once within twelve (12) months of the date of issuance of
such warrants and piggyback registration rights if the Company files a separate
registration statement.

          SECTION 9.2 SPECIFIC ENFORCEMENT, CONSENT TO JURISDICTION.

          (a) The Company and the Purchaser acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent or cure breaches of the provisions of
this Agreement and to enforce specifically the terms and provisions hereof or
thereof, this being in addition to any other remedy to which any of them may be
entitled by law or equity.

          (b) Each of the Company and the Purchaser (i) hereby irrevocably
submits to the jurisdiction of the United States District Court and other courts
of the United States sitting in the State of New York for the purposes of any
suit, action or proceeding arising out of or relating to this Agreement and (ii)
hereby waives, and agrees not to assert in any such suit, action or proceeding,
any claim that it is not personally subject to the jurisdiction of such court,
that the suit, action or proceeding is brought in an inconvenient forum or that
the venue of the suit, action or proceeding is improper. Each of the Company and
the Purchaser consents to process being served in any such suit, action or
proceeding by mailing a copy thereof to such party at the address in effect for
notices to it under this Agreement and agrees that such service shall constitute
good and sufficient service of process and notice thereof. Nothing in this
Section shall affect or limit any right to serve process in any other manner
permitted by law.

          SECTION 9.3 ENTIRE AGREEMENT; AMENDMENT. This Agreement contains the
entire understanding of the parties with respect to the matters covered hereby
and, except as specifically set forth herein, neither the Company nor the
Purchaser makes any representations, warranty, covenant or undertaking with
respect to such matters. No provision of this Agreement may be waived or amended
other than by a written instrument signed by the party against whom enforcement
of any such amendment or waiver is sought.

          SECTION 9.4 NOTICES. Any notice, demand, request, waiver or other

          SECTION 9.5 WAIVERS. No waiver by either party of any default with
respect to any provision, condition or requirement of this Agreement shall be
deemed to be a continuing waiver in the future or a waiver of any other

          SECTION 9.6 HEADINGS. The article, section and subsection headings in

never been contained herein, so that such provisions would be valid, legal and
enforceable to the maximum extent possible.

                         COMMON STOCK PURCHASE AGREEMENT

                               OPINION OF COUNSEL

                     [LETTERHEAD OF _______________________]

                       [FORM OF COMPANY'S COUNSEL OPINION]

     1. The Company is a corporation duly incorporated, validly existing and in
good standing under the laws of the State of Delaware. The Company has the
requisite corporate power to own and operate its properties and assets, and to
carry on its business as presently conducted. The Company is duly qualified to
do business as a foreign corporation and is in good standing in the Commonwealth
of Massachusetts.

     2. The Company has the requisite corporate power and authority to enter
into and perform its obligations under the Purchase Agreement and to issue and
sell the Shares. The execution, delivery and performance of the Purchase
Agreement by the Company and the consummation by it of the transactions
contemplated thereby have been duly and validly authorized by all necessary
corporate action and no further consent or authorization of the Company or its
Board of Directors or stockholders is required. The Purchase Agreement has been
duly executed and delivered by the Company and the Purchase Agreement
constitutes a legal, valid and binding obligation of the Company enforceable
against the Company in accordance with its terms. The Common Stock is not
subject to preemptive rights under the Company's Charter or By-Laws.

     3. The Shares have been duly authorized and, when delivered against payment
in full as provided in the Purchase Agreement, will be validly issued, fully
paid and nonassessable.

     4. The execution, delivery and performance of and compliance with the terms
of the Purchase Agreement and the consummation by the Company of the
transactions contemplated thereby (i) do not violate any provision of the
Company's Charter or By-Laws, (ii) to our knowledge, conflict with, or
constitute a default (or an event which with notice or lapse of time or both
would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation of, any material agreement, mortgage,
deed of trust, indenture, note, bond, license, lease agreement, instrument or
obligation to which the Company is a party, (iii) to our knowledge, create or
impose a lien, charge or encumbrance on any property of the Company under any
agreement or any commitment to which the Company is a party or by which the
Company is bound or by which any of its respective properties or assets are
bound, or (iv) result in a violation of any federal, state or local statute,
rule, regulation, order, judgment or decree (including federal securities laws
and

<PAGE>   33

regulations) applicable to the Company or any of its subsidiaries or by which
any property or asset of the Company or any of its subsidiaries are bound or
affected, except, (in all cases other than violations pursuant to clause (i)
above and clause (iv) to the extent of federal securities laws and regulation)
for such conflicts, defaults, terminations, amendments, acceleration,
cancellations and violations as would not, individually or in the aggregate,
have a Material Adverse Effect.

     5. To our knowledge, there is no action, suit, claim, investigation or
proceeding pending or threatened against the Company or any subsidiary which
questions the validity of this Agreement or the transactions contemplated hereby
or any action taken or to be taken pursuant hereto or thereto. To our knowledge,
there is no action, suit, claim, investigation or proceeding pending or,

                                 CAPITALIZATION

CAPITAL STOCK: As of August 7, 2000, the Company has a total authorized
capitalization of 44,000,000 shares, consisting of (i) 40,000,000 shares of
common stock, par value $0.01 per share, of which 25,034,563 shares are issued
and outstanding and (ii) 4,000,000 shares of preferred stock, par value $1.00
per share, none of which are issued and outstanding.

OPTIONS TO PURCHASE SHARES OF COMMON STOCK: As of August 7, 2000, there are an
aggregate of 1,301,399 options, issued and outstanding, to purchase shares of
the Company's Common Stock. The options have been issued pursuant to (i) the
Company's 1988 Stock Plan, which provides for the issuance of up to 238,875
shares of Common Stock; (ii) the Company's 1992 Stock Plan, as amended, which
provides for the issuance of up to 2,500,000 shares of Common Stock; and (iii)
the Company's Amended and Restated 1992 Non-Employee Director Stock Plan, as
amended, which provides for the issuance of up to 465,000 shares of Common
Stock.

WARRANTS TO PURCHASE SHARES OF COMMON STOCK: As of August 7, 2000, there are
issued and outstanding warrants to purchase an aggregate of 475,637 shares of
the Company's Common Stock. The warrants have been issued pursuant to (i) a
Warrant Agreement dated as of May 28, 1997, by and between the Company and

OTHER COMMITMENTS TO ISSUE SHARES OF COMMON STOCK: Pursuant to a Purchase
Agreement dated as of June 28, 2000, by and among Petra Urban, on behalf of
Franz Maier, Eva Heidt and Joachim Hevler (collectively, the "ADL Sellers"), the
shareholders of ADL-Vertriebsgesellschaft mbH Gesellschaft fur Allergie,
Diagnostika und Laborkonzepte ("ADL"), and Stephen Schmidt, on behalf of the
Company, the Company agreed to issue to the Sellers, within sixty (60) days
after the completion of a financial audit of ADL for the fiscal year ended
December 31, 2000, additional shares of Common Stock of the Company. The number
of shares of Common Stock to be issued to the ADL Sellers will be equal to the
amount obtained by multiplying 20% by the increase in year 2000 revenues over
year 1999 revenues of DM3,580,000 (the "ADL Consideration") at the rate of
0.0844 shares of Common Stock per DM. If year 2000 revenues exceed DM4,395,000,
the amount of the excess over 4,395,000 will be multiplied by 40%, which amount
shall be added to the ADL Consideration. The Company does not expect the ADL
Consideration to exceed approximately 13,700 shares of Common Stock.
