The Principal Shareholders hereby agree to take no action to contravene,

as EXHIBIT B, respectively, and incorporated herein by this reference (the 
"RESOLUTIONS"). If the directors or the shareholders of the Company further 
amend Section 2 of Article II of the Bylaws at any time during which PVALP 
shall own any Preferred Stock or Common Stock, upon the written demand 
therefor by PVALP, each of the Principal Shareholders shall call a special 
meeting of the Shareholders at the sole expense of the Company and they each 
agree that they shall vote all of their Common Shares, whether now

Resolutions, in accordance with Article VII of the Bylaws.


                              ARTICLE II. TRANSFERS

         2.1 TRANSFER OF COMMON SHARES TO AFFILIATES. During the term of this 
Agreement, neither the Principal Shareholders nor any other person who shall 
become a party to or bound by this Agreement shall transfer any Common 
Shares, whether now or hereafter acquired by him or her, (i) to any person 
without the prior written consent of PVALP which consent will not be 
unreasonably withheld, (ii) to any affiliate, as hereinafter defined, without 
first obtaining the prior written consent of PVALP which consent shall not be 
unreasonably withheld, and the written agreement of such affiliate to be 
bound by and subject to the terms and conditions of this Agreement, with the 
same force and effect as if such person were named as a party to this 
Agreement or as a Principal Shareholder hereunder, or (iii) pursuant to a 
registration statement without the prior written approval of PVALP which 
consent will not be unreasonably withheld, or (iv) such that the aggregate 
holdings of the Principal Shareholders shall not equal less than fifty and 
one-tenth of one percent (50.1%) on a fully diluted basis including all of 
the authorized Series C Preferred Stock whether or not actually issued. The 
term "affiliate" shall mean (a) any spouse, parent, parent-in-law, 
grandparent, child, grandchild, sibling, uncle, aunt, niece, nephew or first 
cousin of the transferor or (b) any person which the transferor directly or 
indirectly controls or (c) any transfer to a person if the transferor remains 
a beneficial owner, as that term is used in Section 13(d) of the Securities 
Exchange Act of 1934, as amended, of the transferred shares.

                         ARTICLE III. CO-SALE PROVISIONS

         3.1 THIRD-PARTY OFFER AND NOTICE. Any voluntary or involuntary 
transfer of the Common Shares by any Principal Shareholder will be subject to 
a participation right of co-sale 

<PAGE>
Page 4


by Pioneer Ventures or its assigns on a PRO RATA fully diluted basis. If any one
or more of the Principal Shareholders obtains from a third party ("THIRD PARTY
PURCHASER") an offer to purchase any amount of his or her Shares, such Principal
Shareholders shall submit a written notice (the "CO-SALE NOTICE") to Pioneer
Ventures disclosing the amount of Common Shares proposed to be sold, the offered
purchase price, the proposed closing date, and the total number of Common Shares
owned by the Principal Shareholders.

         3.2 CO-SALE RIGHT OF PARTICIPATION. Upon receipt of a Co-Sale Notice 
from any Principal Shareholders, Pioneer Ventures or its assigns may elect to 
participate in such transaction and shall have the right to offer its 
securities, at the same price and on the same terms, on a fully diluted pro 
rata basis with the proposed selling shareholder(s) as set forth in the offer 
made by the Third Party Purchaser. Each participating selling party shall in 
turn be entitled to receive at the applicable closing the net proceeds of the 
sale allocable to the securities sold on behalf of each selling shareholder, 
after deduction of such selling shareholder's proportionate share of the 
reasonable expenses of the sale. These co-sale provisions will not apply to 
any sale of securities pursuant to a distribution to the public, whether 
pursuant to a registered public offering, Rule 144 or otherwise. If less than 
all of a shareholder's securities are being sold pursuant to this Article 
III, the securities to be sold shall be determined on a pro rata fully 
diluted basis.

         3.3 NOTICE OF INTENT TO PARTICIPATE IN CO-SALE. If Pioneer Ventures 
wishes to participate in any sale under this Article III, then Pioneer 
Ventures shall notify the selling Principal Shareholders in writing of such 
intention as soon as practicable after such Pioneer Ventures' receipt of the 
Co-Sale Notice made pursuant to Section 3.1, and in any event within fifteen 
(15) days after the date of such Co-Sale Notice has been delivered. Such 
notification shall be delivered in person or by facsimile to the Principal 
Shareholders at the Company's offices.

Agreement, such Principal Shareholder consents to the entry of injunctive relief

threatened violation, and/or granting full voting authority to PVALP for
