required under the applicable requirements of such securities Laws.  Purchaser
agrees that, in connection with any Transfer of Warrants or Conversion Shares by
it pursuant to an effective registration statement under the Securities Act,
Purchaser will comply with all prospectus delivery requirements of the

      Section 4.7   Right of First Offer
                    --------------------

              (a)   No later than forty (40) calendar days prior to the
consummation of any Private Placement, and subject to paragraph (e) below, the
Company will deliver to Purchaser, a written notice (the "Offer Notice")
                                                          ------------
specifying (i) the aggregate amount of cash consideration (the "Offer Price")
                                                                -----------
for which the Company proposes to sell the securities that are the subject of
the Private Placement (the "Offered Securities"), (ii) the identity of the
                            ------------------
purchaser in such Private Placement, and (iii) and all other material terms of
the proposed Private Placement. If the Purchaser delivers to the Company a
written notice (an "ROFO Acceptance Notice") within thirty (30) days following
                    ----------------------
delivery of the Offer Notice (the "ROFO Acceptance Period"), stating that the
                                   ----------------------
Purchaser is willing to purchase all or a portion of the Offered Securities on
the terms set forth in the Offer Notice (the "ROFO Accepted Securities"), the
                                              ------------------------
Company will sell such ROFO Accepted Securities to the Purchaser, and the
Purchaser will purchase such ROFO Accepted Securities from the Company, on the
proposed terms and subject to the conditions set forth below.

                                     -25-
<PAGE>

          (b) The consummation of any purchase of the Offered Securities by the
Purchaser pursuant to this Section 4.7 (the "ROFO Closing") will occur on the
                                             ------------
fifth Business Day following the delivery of the ROFO Acceptance Notice (such
five (5) Business Day period being referred to herein as the "ROFO Closing
                                                              ------------
Period") at the principal executive offices of the Company at 10:00 a.m.
------
(Central Time).  At the ROFO Closing,  the Purchaser will deliver to the Company
by certified or official bank check or wire transfer to an account designated by
the Company an amount in immediately available funds equal to (i) in the event
the ROFO Accepted Securities consist of all the Offered Securities, the Offer
Price, or (ii) in the event the ROFO Accepted Securities consist of less than
all the Offered Securities, an amount equal to the Offer Price multiplied by a
fraction, the numerator of which is the number ROFO Accepted Securities and the
denominator of which is the total number of Offered Securities.  Upon receipt or
acknowledgment of payment for the ROFO Accepted Securities, the Company will
deliver one or more certificates evidencing the ROFO Accepted Securities,
together with such other duly executed instruments or documents (executed by the
Company) as may be reasonably requested by the Purchaser to acquire the ROFO
Accepted Securities free and clear of any and all Encumbrances, except for
Encumbrances created by this Agreement, federal or state securities law or the
Purchaser or as specified in the Offer Notice, and  the Company will be deemed
to represent and warrant to the Purchaser that, upon the ROFO Closing, the
Company will convey and the Purchaser will acquire the entire record and
beneficial ownership of, and good and valid title to, the ROFO Accepted
Securities, free and clear of any and all Encumbrances, except for Encumbrances
created by this Agreement, federal or state securities laws or the Purchaser or
as described in the Offer Notice.

          (c) If (i) the ROFO Accepted Securities consist of less than all of
the Offered Securities, or (ii) no Acceptance Notice is delivered to the Company
prior to the expiration of the ROFO Acceptance Period, then the Company may sell
any portion of the Offered Securities not offered to be purchased by the
Purchaser, at a price equal to or greater than that specified in the Offer
Notice and on payment terms no less favorable to the Company than those
specified in the Offer Notice.

          (d) If an Acceptance Notice is delivered to the Company prior to the
expiration of the ROFO Acceptance Period but the ROFO Closing fails to occur
prior to the expiration of the ROFO Closing Period (unless the Purchaser was
ready, willing and able prior to the expiration of the ROFO Closing Period to
consummate the transactions to be consummated by the Purchaser at the ROFO
Closing), the Company may (without affecting its rights, if any, arising out of
such failure) consummate the Private Placement by selling at any time during a
period not to exceed 180 calendar days immediately following the expiration of
the ROFO Acceptance Period, the ROFO Accepted Securities at a price at least
equal to the Per Share Acquisition Price and upon other terms not materially
less favorable to the Company than those set forth in the Offer Notice.

          (e) Anything in this Section 4.7 to the contrary notwithstanding, the
Company shall be under no obligation to provide an Offer Notice if the Per Share
Acquisition Price is equal to or greater than (i) $3.00, for a Private Placement
prior to the first anniversary of the approval

                                     -26-
<PAGE>

of the Share Issuance by the requisite vote of the Company's stockholders (the
"Stockholder Approval"), (ii) $3.50, for a Private Placement on or before the
 --------------------
second anniversary of the Stockholder Approval, or (iii) $4.00, for a Private
Placement occurring prior to the termination of this Agreement.

                                ---------------

      Section 5.1   Indemnification of Purchaser.  Subject to the provisions of

Indemnified Parties from and against any and all Purchaser Indemnified Costs.

      Section 5.3   Defense of Third-Party Claims.  An Indemnified Party shall
                    -----------------------------
give prompt written notice to any person who is obligated to provide
indemnification hereunder (an "Indemnifying Party") of the commencement or
assertion of any action, proceeding, demand, or claim by a third party
(collectively, a "third-party action") in respect of which such Indemnified
Party shall seek indemnification hereunder.  Any failure to so notify an
Indemnifying Party shall not relieve such Indemnifying Party from any liability
that it, he, or she may have to such Indemnified Party under this Section 5.3
unless the failure to give such notice materially and adversely prejudices such
Indemnifying Party.  The Indemnifying Party shall have the right to assume
control of the defense of, settle, or otherwise dispose of such third-party
action on such terms as it deems appropriate; provided, however, that:

                                     -27-
<PAGE>

          (a) The Indemnified Party shall be entitled, at its own expense, to
participate in the defense of such third-party action (provided, however, that
the Indemnifying Party shall pay the attorneys' fees of one counsel (provided
that if any such third-party action is brought in a jurisdiction other than the
State of Delaware, the Indemnifying Party shall also pay the attorney's fees of
one local counsel) to the Indemnified Party if (i) the employment of separate
counsel shall have been authorized in writing by any such Indemnifying Party in
connection with the defense of such third-party action, (ii the Indemnifying
Parties shall not have employed counsel reasonably satisfactory to the
Indemnified Party to have charge of such third-party action, (ii counsel to the
Indemnified Party shall have reasonably concluded that there may be defenses
available to the Indemnified Party that are different from or additional to
those available to the Indemnifying Party, (iv counsel to the Indemnified Party
and the Indemnifying Party shall have advised their respective clients in
writing, with a copy delivered to the other party, that there is a conflict of
interest that could make it inappropriate under applicable standards of
professional conduct to have common counsel), or (v) the third-party action is a
proceeding brought by a stockholder of the Company (in such stockholder's name
or derivatively on behalf of the Company) in respect of the transactions
contemplated by this Agreement;

          (b) The Indemnifying Party shall obtain the prior written approval of
the Indemnified Party before entering into or making any settlement, compromise,
admission, or acknowledgment of the validity of such third-party action or any
liability in respect thereof if, pursuant to or as a result of such settlement,
compromise, admission, or acknowledgment, injunctive or other equitable relief
would be imposed against the Indemnified Party or if, in the opinion of the
Indemnified Party, such settlement, compromise, admission, or acknowledgment
could have a material adverse effect on its business;

          (c) No Indemnifying Party shall consent to the entry of any judgment
or enter into any settlement that does not include as an unconditional term
thereof the giving by each claimant or plaintiff to each Indemnified Party of a
release from all liability in respect of such third-party action; and

          (d) The Indemnifying Party shall not be entitled to control (but shall
be entitled to participate at its own expense in the defense of), and the
Indemnified Party shall be entitled to have sole control over, the defense or
settlement, compromise, admission, or acknowledgment of any third-party action
(i) as to which the Indemnifying Party fails to assume the defense within a
reasonable length of time; or (ii to the extent the third-party action seeks an
order, injunction, or other equitable relief against the Indemnified Party
which, if successful, would materially adversely affect the business,
operations, assets, or financial condition of the Indemnified Party; provided,
however, that the Indemnified Party shall make no settlement, compromise,
admission, or acknowledgment that would give rise to liability on the part of
any Indemnifying Party without the prior written consent of such Indemnifying
Party.

The parties hereto shall extend reasonable cooperation in connection with the
defense of any third-party action pursuant to this Article V and, in connection
therewith, shall furnish such

                                     -28-
<PAGE>

records, information, and testimony and attend such conferences, discovery
proceedings, hearings, trials, and appeals as may be reasonably requested.

      Section 5.4   Direct Claims.  In any case in which an Indemnified Party
                    -------------
seeks indemnification hereunder which is not subject to Section 5.3 because no
third-party action is involved, the Indemnified Party shall notify the
Indemnifying Party in writing of any Indemnified Costs which such Indemnified
Party claims are subject to indemnification under the terms hereof.  The failure
of the Indemnified Party to exercise promptness in such notification shall not
amount to a waiver of such claim unless the resulting delay materially
prejudices the position of the Indemnifying Party with respect to such claim.

      Section 5.5   Limitations.  The provisions of this Section 5.5 shall be
                    -----------
applicable to all claims for indemnification:

              (a)   Minimum Loss.  No Indemnifying Party shall be required to
                    ------------
indemnify an Indemnified Party for Indemnified Costs unless and until the
aggregate amount of such Indemnified Costs for which the Indemnified Party is
otherwise entitled to indemnification pursuant to this Article V exceeds
$100,000 (the "Minimum Loss").  After the Minimum Loss is exceeded, the
Indemnified Party shall be entitled to be paid the entire amount of its
Indemnified Representation Costs in excess of (but not including) the Minimum
Loss, subject to the limitations on recovery and recourse set forth in this
Section 5.5.

              (b)   Limitation as to Time. No Indemnifying Party shall be liable
                    ---------------------
for any Indemnified Costs pursuant to this Article V unless a written claim for
indemnification in accordance with Section 5.3 or 5.4 is given by the
Indemnified Party to the Indemnifying Party with respect thereto on or before
the later to occur of (i) two years from the conversion of the Conversion Note,
or (ii) provided the Conversion Note has not previously been converted for
Conversion Shares, six months after maturity of the Conversion Note.


                                  ARTICLE VI

                                 MISCELLANEOUS
                                 -------------

      Section 6.1   Survival of Provisions.  Subject to the provision of Section
                    ----------------------
5.5, the representations, warranties and covenants (including the
indemnification obligations) of the Company and Purchaser made herein or in any
other Transaction Document shall remain operative and in full force and effect
pursuant to their terms regardless of any investigation made by or on behalf of
Purchaser or the Company, as the case may be.

      Section 6.2   No Waiver; Modification in Writing.  No failure or delay on
                    ----------------------------------
the part of the Company or Purchaser in exercising any right, power or remedy
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right, power or remedy preclude any other or further
exercise thereof or the exercise of any other right, power or remedy.

                                     -29-
<PAGE>

The remedies provided for herein are cumulative and are not exclusive of any
remedies that may be available to the Company or Purchaser at law or in equity.
The provisions of this Agreement, including the provisions of this sentence, may
not be amended, modified or supplemented, and waivers or consents to departures
from the provisions hereof may not be given without the written consent of the
Company, on the one hand, and Purchaser or its Permitted Assignees, on the other
hand, provided that notice of any such waiver shall be given to each party
hereto as set forth below. Any amendment, supplement or modification of or to
any provision of this Agreement, or any waiver of any provision of this
Agreement, shall be effective only in the specific instance and for the specific
purpose for which made or given. Except where notice is specifically required by
this Agreement, no notice to or demand on any party hereto in any case shall
entitle the other party to any other or further notice or demand in similar or
other circumstances.

      Section 6.3   Specific Performance.  The parties recognize that in the
                    --------------------
event the Company should refuse to perform under the provisions of this
Agreement or any other Transaction Document, monetary damages alone will not be
adequate.  Purchaser shall therefore be entitled, in addition to any other
remedies which may be available, including money damages, to obtain specific
performance of the terms of this Agreement and of the obligations undertaken by
the Company or its stockholders in any of the other Transaction Documents,
including, but not limited to, the Voting Agreement.  In the event of any action
to enforce this Agreement or any other Transaction Document specifically, the
Company hereby waives the defense that there is an adequate remedy at law.

      Section 6.4   Severability.  If any term or other provision of this
                    ------------
Agreement is invalid, illegal, or incapable of being enforced by any rule of
applicable law, or public policy, all other conditions and provisions of this
Agreement shall nevertheless remain in full force and effect so long as the
economic or legal substance of the transactions contemplated herein are not
affected in any manner materially adverse to any party.  Upon such determination
that any term or other provision is invalid, illegal, or incapable of being
enforced, the parties hereto shall negotiate in good faith to modify this
Agreement so as to effect the original intent of the parties as closely as
possible in a mutually acceptable manner in order that the transactions
contemplated herein are consummated as originally contemplated to the fullest
extent possible.

      Section 6.5   Parties in Interest.  This Agreement shall be binding upon
                    -------------------
and, except as provided below, inure solely to the benefit of each party hereto
and their successors and assigns, and nothing in this Agreement, except as set
forth in Article V which is intended for the benefit of all Indemnified Parties,
express or implied, is intended to confer upon any other person any rights or
remedies of any nature whatsoever under or by reason of this Agreement.
