                  a.       Mandatory Registration.

                  (i) Initial Mandatory Registration. The Company shall prepare,
and, as soon as practicable, but in no event later than 30 days after the
Initial Closing Date (as defined in the Securities Purchase Agreement) (the
"INITIAL FILING DEADLINE"), file with the SEC an Initial Registration Statement
or Initial Registration Statements (as necessary) on Form S-3 covering the
resale of all of the Initial Registrable Securities. In the event that Form S-3

is available for such a registration, subject to the provisions of Section 2(d).
Any first Registration Statement prepared pursuant hereto shall register for
resale at least that number of shares of Common Stock equal to the sum of (y)
the product of (i) 1.5 and (ii) the number of Initial Conversion Shares issuable
upon conversion of the Initial Preferred Shares (without regard to any
limitations on conversions) as of the date immediately preceding the date the
Initial Registration Statement is initially filed with the SEC, subject to
adjustment as provided in Section 3(b), plus (z) the number of Initial Warrant
Shares issuable upon exercise of the Initial Warrants (without regard to any
limitations on exercise) as of the date immediately preceding the date the
Initial Registration Statement is initially filed with the SEC, subject to
adjustment as provided in Section 3(b). The Company shall use its best efforts
to cause such Registration Statement to be declared effective by the SEC as soon
as possible, but in no event later than 120 days after the Initial Closing Date
(the "INITIAL EFFECTIVENESS DEADLINE").

                  (ii) Additional Mandatory Registration. The Company shall
prepare, and, as soon as practicable, but in no event later than 15 days after
the Additional Share Notice Date

                                       3
<PAGE>   4
(as defined in the Securities Purchase Agreement) (the "ADDITIONAL FILING
DEADLINE"), file with the SEC an Additional Registration Statement or Additional
Registration Statements (as necessary) on Form S-3 covering the resale of all of
the Additional Registrable Securities. In the event that Form S-3 is unavailable
for such a registration, the Company shall use such other form as is available
for such a registration, subject to the provisions of Section 2(d). Any first
Registration Statement prepared pursuant hereto shall register for resale at
least that number of shares of Common Stock equal to the sum of (y) the product
of (i) 1.5 and (ii) the number of Additional Conversion Shares issuable upon
conversion of the Additional Preferred Shares (without regard to any limitations
on conversions) as of the date immediately preceding the date the Additional
Registration Statement is initially filed with the SEC, subject to adjustment as
provided in Section 3(b), plus (z) the number of Additional Warrant Shares
issuable upon exercise of the Additional Warrants (without regard to any
limitations on exercise) as of the date immediately preceding the date the
Additional Registration Statement is initially filed with the SEC, subject to
adjustment as provided in Section 3(b). The Company shall use its best efforts
to cause such Registration Statement to be declared effective by the SEC as soon
as possible, but in no event later than 80 days after the Additional Share
Notice Date (the "INITIAL EFFECTIVENESS DEADLINE").

                  b. Allocation of Registrable Securities. The initial number of
Registrable Securities included in any Registration Statement and each increase
in the number of Registrable Securities included therein shall be allocated pro
rata among the Investors based on the number of Registrable Securities held by
each Investor at the time the Registration Statement covering such initial
number of Registrable Securities or increase thereof is declared effective by
the SEC. In the event that an Investor sells or otherwise transfers any of such
Person's Registrable Securities, each transferee shall be allocated a pro rata
portion of the then remaining number of Registrable Securities included in such
Registration Statement for such transferor. Any shares of Common Stock included
in a Registration Statement and which remain allocated to any Person which
ceases to hold any Registrable Securities covered by such Registration Statement
shall be allocated to the remaining Investors, pro rata based on the number of
Registrable Securities then held by such Investors which are covered by such
Registration Statement.

                  c. Legal Counsel. Subject to Section 5 hereof, the Buyers
holding a majority of the Registrable Securities shall have the right to select
one legal counsel to review and oversee any offering pursuant to this Section 2
("LEGAL COUNSEL"), which shall be Katten Muchin & Zavis or such other counsel as
thereafter designated by the holders of a majority of Registrable Securities.
The Company shall reasonably cooperate with Legal Counsel in performing the
Company's obligations under this Agreement.

                  d. Ineligibility for Form S-3. In the event that Form S-3 is
not available for any registration of the resale of Registrable Securities
hereunder, the Company shall (i) register the resale of the Registrable
Securities on another appropriate form reasonably acceptable to the holders of a
majority of the Registrable Securities and (ii) undertake to register the resale
of the Registrable Securities on Form S-3 as soon as such form is available,
provided that the Company shall maintain the effectiveness of the Registration
Statement then in effect until such time as a Registration Statement on Form S-3
covering the Registrable Securities has been declared effective by the SEC.

                                        4
<PAGE>   5
                  e. Effect of Failure to File and Obtain and Maintain
Effectiveness of Registration Statement. If (i) a Registration Statement
covering all the Registrable Securities and required to be filed by the Company
pursuant to this Agreement is not (A) filed with the SEC on or before the
applicable Filing Deadline or (B) declared effective by the SEC on or before the
applicable Effectiveness Deadline or (ii) on any day after the Registration
Statement has been declared effective by the SEC (other than days during an
Allowable Grace Period (as defined in Section 3(t)), sales of all the
Registrable Securities required to be included on such Registration Statement
cannot be made pursuant to the Registration Statement (including, without
limitation, because of a failure to keep the Registration Statement effective,
to disclose such information as is necessary for sales to be made pursuant to
the Registration Statement, or to register sufficient shares of Common Stock),
then, as partial relief for the damages to any holder by reason of any such
delay in or reduction of its ability to sell the underlying shares of Common
Stock (which remedy shall not be exclusive of any other remedies available at
law or in equity), the Company shall pay to each holder of Preferred Shares an
amount in cash per Preferred Share held equal to the product of (i) $10,000
multiplied by (ii) the sum of (A) .02, if the Registration Statement is not
filed by the Filing Deadline, plus (B) .02, if the Registration Statement is not
declared effective by the Effectiveness Deadline, plus, (C) the product of (I)
 .0005 multiplied by (II) the sum of (x) the number of days after the Filing
Deadline that such Registration Statement is not filed with the SEC, plus (y)
the number of days after the Effectiveness Deadline that the Registration
Statement is not declared effective by the SEC, plus (z) the number of days
after the Registration Statement has been declared effective by the SEC that
such Registration Statement is not available (other than during an Allowable
Grace Period) for the sale of at least all the Registrable Securities required
to be included on such Registration Statement. The payments to which a holder
shall be entitled pursuant to this Section 2(e) are referred to herein as
"REGISTRATION DELAY PAYMENTS." Registration Delay Payments shall be paid on the
earlier of (I) the last day of the calendar month during which such Registration
Delay Payments are incurred and (II) the third business day after the event or
failure giving rise to the Registration Delay Payments is cured. In the event
the Company fails to make Registration Delay Payments in a timely manner, such
Registration Delay Payments shall bear interest at the rate of 1.5% per month
(prorated for partial months) until paid in full.

                  f. Sufficient Number of Shares Registered. In the event the
number of shares available under a Registration Statement filed pursuant to
Section 2(a) is insufficient to cover all of the Registrable Securities which
such Registration Statement is required to cover or an Investor's allocated
portion of the Registrable Securities pursuant to Section 2(b), the Company
shall amend the Registration Statement, or file a new Registration Statement (on
the short form available therefor, if applicable), or both, so as to cover at
least 150% of the Registrable Securities (based on the market price of the
Common Stock on the trading day immediately preceding the date of filing of such
amendment or new Registration Statement), in each case, as soon as practicable,
but in any event not later than fifteen (15) days after the necessity therefor
arises. The Company shall use its best efforts to cause such amendment and/or
new Registration Statement to become effective as soon as practicable following
the filing thereof. For purposes of the foregoing provision, the number of
shares available under a Registration Statement shall be deemed "insufficient to
cover all of the Registrable Securities" if the number of Registrable Securities
issued or issuable upon conversion of the Preferred Shares and exercise of the
Warrants covered by such Registration Statement is greater than the quotient
determined by dividing (i) the number of shares of Common

                                        5
<PAGE>   6
Stock available for resale under such Registration Statement by (ii) 1.35. For
purposes of the calculation set forth in the foregoing sentence, any
restrictions on the convertibility of the Preferred Shares or exercise of the
Warrants shall be disregarded and such calculation shall assume that the
Preferred Shares are then convertible into, and the Warrants are then
exercisable for, shares of Common Stock at the then prevailing Conversion Rate
(as defined in the Articles of Amendment) or Exercise Price (as defined in the
Warrants), respectively.

         3.       RELATED OBLIGATIONS.

         At such time as the Company is obligated to file a Registration
Statement with the SEC pursuant to Section 2(a) or 2(f), the Company will use
its best efforts to effect the registration of the Registrable Securities in
accordance with the intended method of disposition thereof and, pursuant
thereto, the Company shall have the following obligations:

                  a. The Company shall promptly prepare and file with the SEC a
Registration Statement with respect to the applicable Registrable Securities
(but in no event later than the Filing Deadline) and use its best efforts to
cause such Registration Statement relating to the Registrable Securities to
become effective as soon as practicable after such filing (but in no event later
than the applicable Effectiveness Deadline). The Company shall keep each
Registration Statement effective pursuant to Rule 415 at all times until the
earlier of (i) the date as of which the Investors may sell all of the
Registrable Securities covered by such Registration Statement without
restriction pursuant to Rule 144(k) promulgated under the 1933 Act (or successor
thereto) or (ii) the date on which the Investors shall have sold all the
Registrable Securities covered by such Registration Statement (the "REGISTRATION
PERIOD"), which Registration Statement (including any amendments or supplements
thereto and prospectuses contained therein) shall not contain any 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 light of the
circumstances in which they were made, not misleading. The term "best efforts"
as used in the first sentence of this Section 3(a) shall mean, among other
things, that the Company shall submit to the SEC, within two business days after
the Company learns that no review of a particular Registration Statement will be
made by the staff of the SEC or that the staff has no further comments on the
Registration Statement, as the case may be, a request for acceleration of
effectiveness of such Registration Statement to a time and date not later than
48 hours after the submission of such request.

                  b. The Company shall prepare and file with the SEC such
amendments (including post-effective amendments) and supplements to a
Registration Statement and the prospectus used in connection with such
Registration Statement, which prospectus is to be filed pursuant to Rule 424
promulgated under the 1933 Act, as may be necessary to keep such Registration
Statement effective at all times during the Registration Period, and, during
such period, comply with the provisions of the 1933 Act with respect to the
disposition of all Registrable Securities of the Company covered by such
Registration Statement until such time as all of such Registrable Securities
shall have been disposed of in accordance with the intended methods of
disposition by the seller or sellers thereof as set forth in such Registration
Statement. In the case of amendments and supplements to a Registration Statement
which are required to be filed pursuant to this Agreement (including pursuant to
this Section 3(b)) by reason of the Company filing a report on Form 10-K, Form
10-Q or Form

                                        6
<PAGE>   7
8-K or any analogous report under the Securities Exchange Act of 1934, as
amended (the "1934 ACT"), the Company shall have incorporated such report by
reference into the Registration Statement, if applicable, or shall file such
amendments or supplements with the SEC on the same day on which the 1934 Act
report is filed which created the requirement for the Company to amend or
supplement the Registration Statement.

                  c. The Company shall (a) permit Legal Counsel to review and
comment upon those sections of (i) the Initial Registration Statement at least
five (5) business days prior to its filing with the SEC, (ii) the Additional
Registration Statement at least three (3) Business Days prior to its filing with
the SEC and (iii) all other Registration Statements and all amendments and
supplements to all Registration Statements which are applicable to the Buyers
(except for Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and
Current Reports on Form 8-K and any similar or successor reports) within a
reasonable number of days prior to the their filing with the SEC and (b) not
file any document in a form to which Legal Counsel reasonably objects. The
Company shall not submit a request for acceleration of the effectiveness of a
Registration Statement or any amendment or supplement thereto without the prior
approval of Legal Counsel, which consent shall not be unreasonably withheld. The
Company shall furnish to Legal Counsel, without charge, (i) any correspondence
from the SEC or the staff of the SEC to the Company or its representatives
relating to any Registration Statement, (ii) promptly after the same is prepared
and filed with the SEC, one copy of any Registration Statement and any
amendment(s) thereto, including financial statements and schedules and all
exhibits and (iii) upon the effectiveness of any Registration Statement, one
copy of the prospectus included in such Registration Statement and all
amendments and supplements thereto. The Company shall reasonably cooperate with
Legal Counsel in performing the Company's obligations pursuant to this Section
3.

                  d. The Company shall furnish to each Investor whose
Registrable Securities are included in any Registration Statement, without
charge, (i) promptly after the same is prepared and filed with the SEC, at least
one copy of such Registration Statement and any amendment(s) thereto, including
financial statements and schedules, and all exhibits and each preliminary
prospectus, (ii) upon the effectiveness of any Registration Statement, ten (10)
copies of the prospectus included in such Registration Statement and all
amendments and supplements thereto (or such other number of copies as such
Investor may reasonably request) and (iii) such other documents, including
copies of any preliminary or final prospectus, as such Investor may reasonably
request from time to time in order to facilitate the disposition of the
Registrable Securities owned by such Investor.

                  e. The Company shall use its best efforts to (i) register and
qualify, unless an exemption from registration and qualification applies, the
Registrable Securities covered by a Registration Statement under all other
securities or "blue sky" laws of such jurisdictions in the United States, (ii)
prepare and file in those jurisdictions, such amendments (including
post-effective amendments) and supplements to such registrations and
qualifications as may be necessary to maintain the effectiveness thereof during
the Registration Period, (iii) take such other actions as may be necessary to
maintain such registrations and qualifications in effect at all times during the
Registration Period, and (iv) take all other actions reasonably necessary or
advisable to qualify the Registrable Securities for sale in such jurisdictions;
provided, however, that the Company shall not be required in connection
therewith or as a condition thereto to (w) make any change in the

                                        7
<PAGE>   8
Company's Certificate of Incorporation or by-laws that the Company's board of
directors determines in good faith to be contrary to the best interests of the
Company and its shareholders, (x) qualify to do business in any jurisdiction
where it would not otherwise be required to qualify but for this Section 3(e),
(y) subject itself to general taxation in any such jurisdiction, or (z) file a
general consent to service of process in any such jurisdiction. The Company
shall promptly notify Legal Counsel and each Investor who holds Registrable
Securities of the receipt by the Company of any notification with respect to the
suspension of the registration or qualification of any of the Registrable
Securities for sale under the securities or "blue sky" laws of any jurisdiction
in the United States or its receipt of actual notice of the initiation or threat
of any proceeding for such purpose.

                  f. As promptly as practicable after becoming aware of such
event or development, the Company shall notify Legal Counsel and each Investor
in writing of the happening of any event as a result of which the prospectus
included in a Registration Statement, as then in effect, includes an untrue
statement of a material fact or omission to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, and promptly prepare a
supplement or amendment to such Registration Statement to correct such untrue
statement or omission, and deliver ten (10) copies of such supplement or
amendment to Legal Counsel and each Investor (or such other number of copies as
Legal Counsel or such Investor may reasonably request). The Company shall also
promptly notify Legal Counsel and each Investor in writing (i) when a prospectus
or any prospectus supplement or post-effective amendment has been filed, and
when a Registration Statement or any post-effective amendment has become
effective (notification of such effectiveness shall be delivered to Legal
Counsel and each Investor by facsimile on the same day of such effectiveness),
(ii) of any request by the SEC for amendments or supplements to a Registration
Statement or related prospectus or related information, and (iii) of the
Company's reasonable determination that a post-effective amendment to a
Registration Statement would be appropriate.

                  g. The Company shall use its best efforts to prevent the
issuance of any stop order or other suspension of effectiveness of a
Registration Statement, or the suspension of the qualification of any of the
Registrable Securities for sale in any jurisdiction and, if such an order or
suspension is issued, to obtain the withdrawal of such order or suspension at
the earliest possible moment and to notify Legal Counsel and each Investor who
holds Registrable Securities being sold of the issuance of such order and the
resolution thereof or its receipt of actual notice of the initiation or threat
of any proceeding for such purpose.

                  h. At the reasonable request of any Investor and at such
Investor's expense, the Company shall furnish to such Investor, on the date of
the effectiveness of the Registration Statement and thereafter from time to time
on such dates as an Investor may reasonably request (i) a letter, dated such
date, from the Company's independent certified public accountants in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, and (ii) an opinion, dated as
of such date, of counsel representing the Company for purposes of such
Registration Statement, in form, scope and substance as is customarily given in
an underwritten public offering, addressed to the Investors.


                                        8
<PAGE>   9
                  i. The Company shall make available for inspection by (i) any
Investor, (ii) Legal Counsel and (iii) one firm of accountants or other agents
retained by the Investors (collectively, the "INSPECTORS") all pertinent
financial and other records, and pertinent corporate documents and properties of
the Company (collectively, the "RECORDS"), as shall be reasonably deemed
necessary by each Inspector, and cause the Company's officers, directors and
employees to supply all information which any Inspector may reasonably request;
provided, however, that each Inspector shall agree, and each Investor hereby
agrees, to hold in strict confidence and shall not make any disclosure (except
to an Investor) or use of any Record or other information which the Company
determines in good faith to be confidential, and of which determination the
Inspectors are so notified, unless (a) the disclosure of such Records is
necessary to avoid or correct a misstatement or omission in any Registration
Statement or is otherwise required under the 1933 Act, (b) the release of such
Records is ordered pursuant to a final, non-appealable subpoena or order from a
court or government body of competent jurisdiction, or (c) the information in
such Records has been made generally available to the public other than by
disclosure in violation of this or any other agreement of which the Inspector
has knowledge, provided further, however, that each Investor agrees to comply
with applicable Federal securities laws with respect to trading in securities of
the Company while in possession of material nonpublic information concerning the
Company as a result of the inspections provided for in this Section 3(i). The
Company shall not be required to disclose any confidential information in such
Records to any Inspector until and unless such Inspector shall have entered into
confidentiality agreements with the Company with respect thereto, substantially
in the form of this Section 3(i). Each Investor agrees that it shall, upon
learning that disclosure of such Records is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt
notice to the Company and allow the Company, at its expense, to undertake
appropriate action to prevent disclosure of, or to obtain a protective order
for, the Records deemed confidential.

                  j. The Company shall hold in confidence and not make any
disclosure of information concerning an Investor provided to the Company unless
(i) disclosure of such information is necessary to comply with federal or state
securities laws, (ii) the disclosure of such information is necessary to avoid
or correct a misstatement or omission in any Registration Statement, (iii) the
release of such information is ordered pursuant to a subpoena or other final,
non-appealable order from a court or governmental body of competent
jurisdiction, or (iv) such information has been made generally available to the
public other than by disclosure in violation of this Agreement or any other
agreement, or (v) such Investor consents to the form and content of any such
disclosure. The Company agrees that it shall, upon learning that disclosure of
such information concerning an Investor is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt
written notice to such Investor and allow such Investor, at the Investor's
expense, to undertake appropriate action to prevent disclosure of, or to obtain
a protective order for, such information.

                  k. The Company shall use its best efforts either to (i) cause
all the Registrable Securities covered by a Registration Statement to be listed
on each securities exchange on which securities of the same class or series
issued by the Company are then listed, if any, if the listing of such
Registrable Securities is then permitted under the rules of such exchange, or
(ii) secure designation and quotation of all the Registrable Securities covered
by the Registration Statement on

                                        9
<PAGE>   10
the Nasdaq National Market or The New York Stock Exchange, Inc., or, if, despite
the Company's best efforts to satisfy the preceding clause (i) or (ii), the
Company is unsuccessful in satisfying the preceding clause (i) or (ii), to
secure the inclusion for quotation on The American Stock Exchange, Inc. or The
Nasdaq SmallCap Market for such Registrable Securities and, without limiting the
generality of the foregoing, to arrange for at least two market makers to
register with the National Association of Securities Dealers, Inc. ("NASD") as
such with respect to such Registrable Securities. The Company shall pay all fees
and expenses in connection with satisfying its obligation under this Section
3(k).

                  l. The Company shall cooperate with the Investors who hold
Registrable Securities being offered, and to the extent applicable, to
facilitate the timely preparation and delivery of certificates (not bearing any
restrictive legend) representing the Registrable Securities to be offered
pursuant to a Registration Statement and enable such certificates to be in such
denominations or amounts, as the case may be, as the Investors may reasonably
request and registered in such names as the Investors may request.

                  m. The Company shall provide a transfer agent and registrar of
all such Registrable Securities not later than the effective date of such
Registration Statement.

                  n. If requested by an Investor, the Company shall (i) as soon
as practicable incorporate in a prospectus supplement or post-effective
amendment such information as an Investor requests to be included therein
relating to the sale and distribution of Registrable Securities, including,
without limitation, information with respect to the number of Registrable
Securities being offered or sold, the purchase price being paid therefor and any
other terms of the offering of the Registrable Securities to be sold in such
offering; (ii) as soon as practicable make all required filings of such
prospectus supplement or post-effective amendment after being notified of the
matters to be incorporated in such prospectus supplement or post-effective
amendment; and (iii) supplement or make amendments to any Registration Statement
if reasonably requested by an Investor of such Registrable Securities.

                  o. The Company shall use its best efforts to cause the
Registrable Securities covered by the applicable Registration Statement to be
registered with or approved by such other governmental agencies or authorities
as may be necessary to consummate the disposition of such Registrable
Securities.

                  p. The Company shall make generally available to its security
holders as soon as practical, but not later than 90 days after the close of the
period covered thereby, an earnings statement (in form complying with the
provisions of Rule 158 under the 1933 Act) covering a twelve-month period
beginning not later than the first day of the Company's fiscal quarter next
following the effective date of the Registration Statement.

                  q. The Company shall otherwise use its best efforts to comply
with all applicable rules and regulations of the SEC in connection with any
registration hereunder.


                                       10
<PAGE>   11
                  r. Within two (2) business days after a Registration Statement
which covers applicable Registrable Securities is ordered effective by the SEC,
the Company shall deliver, and shall cause legal counsel for the Company to
deliver, to the transfer agent for such Registrable Securities (with copies to
the Investors whose Registrable Securities are included in such Registration
Statement) confirmation that such Registration Statement has been declared
effective by the SEC in the form attached hereto as Exhibit A.

                  s. The Company shall take all other reasonable actions
necessary to expedite and facilitate disposition by the Investors of Registrable
Securities pursuant to a Registration Statement.

                  t. Notwithstanding anything to the contrary in Section 3(f),
at any time after the applicable Registration Statement has been declared
effective by the SEC, the Company may delay the disclosure of material
non-public information concerning the Company the disclosure of which at the
time is not, in the good faith opinion of the Board of Directors of the Company
after consultation with its counsel, in the best interest of the Company and, is
not otherwise required to be disclosed (a "GRACE PERIOD"); provided, that the
Company shall promptly (i) notify the Investors in writing of the existence of
material non-public information giving rise to a Grace Period (provided that in
each notice the Company will not disclose the content of such material
non-public information to the Investors) and the date on which the Grace Period
will begin, and (ii) notify the Investors in writing of the date on which the
Grace Period ends; and, provided further, that no Grace Periods shall exceed 15
consecutive days and during any consecutive 365 day period, such Grace Periods
shall not exceed an aggregate of 30 days (an "ALLOWABLE GRACE PERIOD"). For
purposes of determining the length of a Grace Period above, the Grace Period
shall begin on and include the date the holders receive the notice referred to
in clause (i) and shall end on and include the later of the date the holders
receive the notice referred to in clause (ii) and the date referred to in such
notice. The provisions of Section 2(e) and the first sentence of Section 3(f)
hereof shall not be applicable during the period of any Allowable Grace Period.
Upon expiration of the Grace Period, the Company shall again be bound by the
first sentence of Section 3(f) with respect to the information giving rise
thereto unless such material non-public information is no longer applicable.

         4.       OBLIGATIONS OF THE INVESTORS.

                  a. At least seven (7) days prior to the first anticipated
filing date of a Registration Statement, the Company shall notify each Investor
in writing of the information the Company requires from each such Investor if
such Investor elects to have any of such Investor's Registrable Securities
included in such Registration Statement. It shall be a condition precedent to
the obligations of the Company to complete the registration pursuant to this
Agreement with respect to the Registrable Securities of a particular Investor
that such Investor shall furnish to the Company such information regarding
itself, the Registrable Securities held by it and the intended method of
disposition of the Registrable Securities held by it as shall be reasonably
required to effect the registration of such Registrable Securities and shall
execute such documents in connection with such registration as the Company may
reasonably request.

                  b. Each Investor by such Investor's acceptance of the
Registrable Securities agrees to cooperate with the Company as reasonably
requested by the Company in connection with

                                       11
<PAGE>   12
the preparation and filing of any Registration Statement hereunder, unless such
Investor has notified the Company in writing of such Investor's election to
exclude all of such Investor's Registrable Securities from such Registration
Statement.

                  c. Each Investor agrees that, upon receipt of any notice from
the Company of the happening of any event of the kind described in Section 3(g)
or the first sentence of 3(f), such Investor will immediately discontinue
disposition of Registrable Securities pursuant to any Registration Statement(s)
covering such Registrable Securities until such Investor's receipt of the copies
of the supplemented or amended prospectus contemplated by Section 3(g) or the
first sentence of 3(f) or receipt of notice that no supplement or amendment is
required. Notwithstanding anything to the contrary, the Company shall cause its
transfer agent to deliver unlegended shares of Common Stock to a transferee of
an Investor in accordance with the terms of the Securities Purchase Agreement in
connection with any sale of Registrable Securities with respect to which an
Investor has entered into a contract for sale prior to the Investor's receipt of
a notice from the Company of the happening of any event of the kind described in
Section 3(g) or the first sentence of 3(h) and for which the Investor has not
yet settled.

         5.       EXPENSES OF REGISTRATION.

                  All reasonable expenses, other than underwriting discounts and
commissions, incurred in connection with registrations, filings or
qualifications pursuant to Sections 2 and 3, including, without limitation, all
registration, listing and qualifications fees, printers and accounting fees
shall be paid by the Company.

         6.       INDEMNIFICATION.

                  In the event any Registrable Securities are included in a
Registration Statement under this Agreement:

                  a. To the fullest extent permitted by law, the Company will,
and hereby does, indemnify, hold harmless and defend each Investor, the
directors, officers, partners, employees, agents, representatives of, and each
Person, if any, who controls any Investor within the meaning of the 1933 Act or
the Securities Exchange Act of 1934, as amended (the "1934 ACT") (each, an
"INDEMNIFIED PERSON"), against any losses, claims, damages, liabilities,
judgments, fines, penalties, charges, costs, reasonable attorneys' fees, amounts
paid in settlement or expenses, joint or several, (collectively, "CLAIMS")
incurred in investigating, preparing or defending any action, claim, suit,
inquiry, proceeding, investigation or appeal taken from the foregoing by or
before any court or governmental, administrative or other regulatory agency,
body or the SEC, whether pending or threatened, whether or not an indemnified
party is or may be a party thereto ("INDEMNIFIED DAMAGES"), to which any of them
may become subject insofar as such Claims (or actions or proceedings, whether
commenced or threatened, in respect thereof) arise out of or are based upon: (i)
any untrue statement or alleged untrue statement of a material fact in a
Registration Statement or any post-effective amendment thereto or in any filing
made in connection with the qualification of the offering under the securities
or other "blue sky" laws of any jurisdiction in which Registrable Securities are
offered ("BLUE SKY FILING"), or the omission or alleged omission to state a
material

                                       12
<PAGE>   13
fact required to be stated therein or necessary to make the statements therein
not misleading, (ii) any untrue statement or alleged untrue statement of a
material fact contained in any preliminary prospectus if used prior to the
effective date of such Registration Statement, or contained in the final
prospectus (as amended or supplemented, if the Company files any amendment
thereof or supplement thereto with the SEC) or the omission or alleged omission
to state therein any material fact necessary to make the statements made
therein, in light of the circumstances under which the statements therein were
made, not misleading or (iii) any violation or alleged violation by the Company
of the 1933 Act, the 1934 Act, any other law, including, without limitation, any
state securities law, or any rule or regulation thereunder relating to the offer
or sale of the Registrable Securities pursuant to a Registration Statement (the
matters in the foregoing clauses (i) through (iii) being, collectively,
"VIOLATIONS"). Subject to Section 6(c), the Company shall reimburse the
Investors and each such controlling person, promptly as such expenses are
incurred and are due and payable, for any legal fees or disbursements or other
reasonable expenses incurred by them in connection with investigating or
defending any such Claim. Notwithstanding anything to the contrary contained
herein, the indemnification agreement contained in this Section 6(a): (i) shall
not apply to a Claim by an Indemnified Person arising out of or based upon a
Violation which occurs in reliance upon and in conformity with information
furnished in writing to the Company by such Indemnified Person expressly for use
in connection with the preparation of the Registration Statement or any such
amendment thereof or supplement thereto, if such prospectus was timely made
available by the Company pursuant to Section 3(d); (ii) shall not be available
to the extent such Claim is based on a failure of the Investor to deliver or to
cause to be delivered the prospectus made available by the Company, if such
prospectus was timely made available by the Company pursuant to Section 3(d);
and (iii) shall not apply to amounts paid in settlement of any Claim, if such
settlement is effected without the prior written consent of the Company, which
consent shall not be unreasonably withheld. Such indemnity shall remain in full
force and effect regardless of any investigation made by or on behalf of the
Indemnified Person and shall survive the transfer of the Registrable Securities
by the Investors pursuant to Section 9.

                  b. In connection with any Registration Statement in which an
Investor is participating, each such Investor agrees severally and not jointly
to indemnify, hold harmless and defend, to the same extent and in the same
manner as is set forth in Section 6(a), the Company, each of its directors, each
of its officers who signs the Registration Statement and each Person, if any,
who controls the Company within the meaning of the 1933 Act or the 1934 Act
(each an "INDEMNIFIED PARTY"), against any Claim or Indemnified Damages to which
any of them may become subject, under the 1933 Act, the 1934 Act or otherwise,
insofar as such Claim or Indemnified Damages arise out of or are based upon any
Violation, in each case to the extent, and only to the extent, that such
Violation occurs in reliance upon and in conformity with written information
furnished to the Company by such Investor expressly for use in connection with
such Registration Statement; and, subject to Section 6(d), such Investor will
reimburse any legal or other expenses reasonably incurred by them in connection
with investigating or defending any such Claim; provided, however, that the
indemnity agreement contained in this Section 6(b) and the agreement with
respect to contribution contained in Section 7 shall not apply to amounts paid
in settlement of any Claim if such settlement is effected without the prior
written consent of such Investor, which consent shall not be unreasonably
withheld; provided, further, however, that the Investor shall be liable under
this Section 6(b) for only that amount of a Claim or Indemnified Damages as does
not

                                       13
<PAGE>   14
exceed the net proceeds to such Investor as a result of the sale of Registrable
Securities pursuant to such Registration Statement. Such indemnity shall remain
in full force and effect regardless of any investigation made by or on behalf of
such Indemnified Party and shall survive the transfer of the Registrable
Securities by the Investors pursuant to Section 9. Notwithstanding anything to
the contrary contained herein, the indemnification agreement contained in this
Section 6(b) with respect to any prospectus shall not inure to the benefit of
any Indemnified Party if the untrue statement or omission of material fact
contained in the prospectus was corrected on a timely basis in the prospectus,
as then amended or supplemented.

                  c. Promptly after receipt by an Indemnified Person or
Indemnified Party under this Section 6 of notice of the commencement of any
action or proceeding (including any governmental action or proceeding) involving
a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in
respect thereof is to be made against any indemnifying party under this Section
6, deliver to the indemnifying party a written notice of the commencement
thereof, and the indemnifying party shall have the right to participate in, and,
to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume control of the defense thereof
with counsel mutually satisfactory to the indemnifying party and the Indemnified
Person or the Indemnified Party, as the case may be; provided, however, that an
Indemnified Person or Indemnified Party shall have the right to retain its own
counsel with the fees and expenses of not more than one counsel for such
Indemnified Person or Indemnified Party to be paid by the indemnifying party,
if, in the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel of the Indemnified Person or Indemnified Party
and the indemnifying party would be inappropriate due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any
other party represented by such counsel in such proceeding. In the case of an
Indemnified Person, legal counsel referred to in the immediately preceding
sentence shall be selected by the Investors holding a majority in interest of
the Registrable Securities included in the Registration Statement to which the
Claim relates. The Indemnified Party or Indemnified Person shall cooperate fully
with the indemnifying party in connection with any negotiation or defense of any
such action or claim by the indemnifying party and shall furnish to the
indemnifying party all information reasonably available to the Indemnified Party
or Indemnified Person which relates to such action or claim. The indemnifying
party shall keep the Indemnified Party or Indemnified Person fully apprised at
all times as to the status of the defense or any settlement negotiations with
respect thereto. No indemnifying party shall be liable for any settlement of any
action, claim or proceeding effected without its prior written consent,
provided, however, that the indemnifying party shall not unreasonably withhold,
delay or condition its consent. No indemnifying party shall, without the prior
written consent of the Indemnified Party or Indemnified Person, consent to entry
of any judgment or enter into any settlement or other compromise which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party or Indemnified Person of a release from all liability
in respect to such claim or litigation. Following indemnification as provided
for hereunder, the indemnifying party shall be subrogated to all rights of the
Indemnified Party or Indemnified Person with respect to all third parties, firms
or corporations relating to the matter for which indemnification has been made.
The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall not relieve such
indemnifying party of any liability to the

                                       14
<PAGE>   15
Indemnified Person or Indemnified Party under this Section 6, except to the
extent that the indemnifying party is prejudiced in its ability to defend such
action.

                  d. The indemnification required by this Section 6 shall be
made by periodic payments of the amount thereof during the course of the
investigation or defense, as and when bills are received or Indemnified Damages
are incurred.

                  e. The indemnity agreements contained herein shall be in
addition to (i) any cause of action or similar right of the Indemnified Party or
Indemnified Person against the indemnifying party or others, and (ii) any
liabilities the indemnifying party may be subject to pursuant to the law.

         7.       CONTRIBUTION.

                  To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no seller of Registrable Securities guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be entitled to
contribution from any seller of Registrable Securities who was not guilty of
fraudulent misrepresentation; and (ii) contribution by any seller of Registrable
Securities shall be limited in amount to the net amount of proceeds received by
such seller from the sale of such Registrable Securities pursuant to such
Registration Statement.

         8.       REPORTS UNDER THE 1934 ACT.

                  With a view to making available to the Investors the benefits
of Rule 144 promulgated under the 1933 Act or any other similar rule or
regulation of the SEC that may at any time permit the Investors to sell
securities of the Company to the public without registration ("RULE 144"), the
Company agrees to:

                  a. make and keep public information available, as those terms
are understood and defined in Rule 144;

                  b. file with the SEC in a timely manner all reports and other
documents required of the Company under the 1933 Act and the 1934 Act so long as
the Company remains subject to such requirements (it being understood that
nothing herein shall limit the Company's obligations under Section 4(c) of the
Securities Purchase Agreement) and the filing of such reports and other
documents is required for the applicable provisions of Rule 144; and

                  c. furnish to each Investor so long as such Investor owns
Registrable Securities, promptly upon request, (i) a written statement by the
Company that it has complied with the reporting requirements of Rule 144, the
1933 Act and the 1934 Act, (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the

                                       15
<PAGE>   16
Company, and (iii) such other information as may be reasonably requested to
permit the investors to sell such securities pursuant to Rule 144 without
registration.

         9.       ASSIGNMENT OF REGISTRATION RIGHTS.

                  The rights under this Agreement shall be automatically
assignable by the Buyers and Permitted Assignees (as defined below) to (i)
without the consent of the Company, any person or entity who, immediately prior
to such assignment, is (A) an affiliate of such Buyer or Permitted Assignee, (B)
a holder of Preferred Shares or Warrants or (C) an entity or fund which has the
same principal investment adviser or manager as such Buyer or Permitted Assignee
or any other holder of Preferred Shares, provided such adviser or manager has
the sole power to make decisions regarding any actions taken by such entity or
fund in connection with the Transaction Documents (as defined in the Securities
Purchase Agreement) (each such person or entity described in the immediately
preceding clause (A), (B) and (C) is referred to as "PERMITTED ASSIGNEE") and
(ii) with the prior written consent of the Company, which consent shall not be
unreasonably withheld, to any person or entity; provided, however, that any such
assignment shall not release such Buyer or Permitted Assignee from its
obligations hereunder unless such obligations are assumed by such assignee and
the Company has consented to such assignment and assumption, which consent shall
not be unreasonably withheld.

         10.      AMENDMENT OF REGISTRATION RIGHTS.

                  Provisions of this Agreement may be amended and the observance
thereof may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with the written consent of the Company
and Investors who then hold at least two-thirds (2/3) of the Registrable
Securities. Any amendment or waiver effected in accordance with this Section 10
shall be binding upon each Investor and the Company. No such amendment shall be
effective to the extent that it applies to less than all of the holders of the
Registrable Securities. No consideration shall be offered or paid to any Person
to amend or consent to a waiver or modification of any provision of any of this
Agreement unless the same consideration also is offered to all of the parties to
this Agreement.

         11.      MISCELLANEOUS.

                  a. A Person is deemed to be a holder of Registrable Securities
whenever such Person owns or is deemed to own of record such Registrable
Securities. If the Company receives conflicting instructions, notices or
elections from two or more Persons with respect to the same Registrable
Securities, the Company shall act upon the basis of instructions, notice or
election received from the registered owner of such Registrable Securities.

internal laws of the State of New York, without giving effect to any choice of

any other jurisdictions) that would cause the application of the laws of any
jurisdictions other than the State of New York. Each party hereby irrevocably
submits to the non-exclusive jurisdiction of the state and federal courts
sitting the City of New York, borough of Manhattan, for the adjudication of any
dispute hereunder or in connection herewith or with any transaction contemplated
hereby or discussed herein, and hereby irrevocably waives, and agrees not to
assert in any suit, action or proceeding, any claim that it is not personally
subject to the jurisdiction of any such court, that such suit, action or
proceeding is brought in an inconvenient forum or that the venue of such suit,
action or proceeding is improper. Each party hereby irrevocably waives personal
service of process and consents to process being served in any such suit, action
or proceeding by mailing a copy thereof to such party at the address for such

good and sufficient service of process and notice thereof. Nothing contained

unenforceable in any jurisdiction, such invalidity or unenforceability shall not
affect the validity or enforceability of the remainder of this Agreement in that
jurisdiction or the validity or enforceability of any provision of this
Agreement in any other jurisdiction. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY
RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION
OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS
AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

                  e. This Agreement, the Securities Purchase Agreement, the
Warrants and the Articles of Amendment constitute the entire agreement among the
parties hereto with respect to the subject matter hereof and thereof. There are
no restrictions, promises, warranties or undertakings, other than those set
forth or referred to herein and therein. This Agreement, the Securities Purchase
Agreement, the Warrants and the Articles of Amendment supersede all prior
agreements and understandings among the parties hereto with respect to the
subject matter hereof and thereof.

                  f. Subject to the requirements of Section 9, this Agreement
shall inure to the benefit of and be binding upon the permitted successors and

                  Re:      WAVO CORPORATION

Ladies and Gentlemen:

         We are counsel to WAVO Corporation, an Indiana corporation (the
"COMPANY"), and have represented the Company in connection with that certain
Securities Purchase Agreement (the "PURCHASE AGREEMENT") entered into by and
among the Company and the Buyer named therein (collectively, the "HOLDERS")
pursuant to which the Company issued to the Holders shares of its Preferred
Stock, no par value per share (the "PREFERRED SHARES") convertible into shares
of the Company's common stock, no par value per share (the "COMMON STOCK"), and
the related Warrants (the "THE WARRANTS") to acquire shares of Common Stock.
Pursuant to the Purchase Agreement, the Company also has entered into a
Registration Rights Agreement with the Holders (the "REGISTRATION RIGHTS
AGREEMENT") pursuant to which the Company agreed, among other things, to
register the Registrable Securities (as defined in the Registration Rights
Agreement), including the shares of Common Stock issuable upon conversion of the
Preferred Shares and exercise of the Warrants, under the Securities Act of 1933,
as amended (the "1933 ACT"). In connection with the Company's obligations under
the Registration Rights Agreement, on ____________ ____, the Company filed a
Registration Statement on Form S-3 (File No. 333- _____________) (the
"REGISTRATION STATEMENT") with the Securities and Exchange Commission (the
"SEC") relating to the Registrable Securities which names each of the Holders as
a selling stockholder thereunder.

         In connection with the foregoing, we advise you that a member of the
SEC's staff has advised us by telephone that the SEC has entered an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,
after telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

                                                     Very truly yours,

                                                     [ISSUER'S COUNSEL]

                                                     By:________________________
