              (b) In the event of an increase in the size of the Board of
Directors, so long as the Investor Stock represents 20% or more of the

entitled to designate additional directors such that the Investor Directors at
all times constitute a simple majority of the Board of Directors.

              (c) The Company and Stockholders agree to appoint one IBJS

Company's Board of Directors.

              (d) The Stockholders shall vote their shares of stock (i) to

              (e) Representatives of the Investors shall have the right to

that a quorum of the Board of Directors shall require the presence of a majority
of the Investor Directors and any action with respect to compensation or bonuses

of a majority of the Investor Directors. Such bylaw provisions shall not be
further amended without the consent of the Investors.

              (g) Each Stockholder agrees to cooperate with the Company in all
reasonable respects in complying with the terms and provisions of Sections 6(m),
(n) and (o) of the Exchange Agreement, including without limitation voting to
approve such amendments to the Company's certificate of incorporation and
by-laws and this Agreement as may be reasonably requested by any Regulated
Holder (as defined in the Exchange Agreement) entitled to make such request
pursuant to the Exchange Agreement. Notwithstanding the foregoing, no
Stockholder shall be required by this provision to take any action that would
materially and adversely affect its rights under this Agreement or as a
stockholder of the Company.

              (h) The Company and the Stockholders agree not to amend or waive
the voting or other provisions of the Company's certificate of incorporation or
by-laws or this Agreement if such amendment or waiver would cause any Regulated
Holder to have a Regulatory Problem (as 

                                       3
<PAGE>


defined in the Exchange Agreement) and such Regulated Holder has so notified the
Company that it would have a Regulatory Problem promptly after it has notice of 
such proposed amendment or waiver.

              (i) The provisions of this Section 2 shall terminate in the event
that a majority of the Company's outstanding Preferred Stock is held by persons
other than the Investors.

         SECTION 3. Tag-Along Rights.

              (a) No Stockholder shall transfer any Common Stock or
Common-Equivalent Securities other than in compliance with the provisions of
this Section 3. If any Stockholder (the "Transferring Stockholder") proposes to
transfer any Common Stock or Common-Equivalent Securities to one or more third
parties (collectively, a "Third Party"), the Transferring Stockholder shall give
written notice (a "Tag-Along Notice") to each other Stockholder, which notice
shall identify the proposed Third Party purchaser and state the number of shares
of Common Stock or Common-Equivalent Securities proposed to be transferred, the
proposed offering price and any other material terms and conditions of the
proposed transfer. The Tag- Along Notice shall also contain a true and correct
copy of any offer by the Third Party offeror.

              (b) Each other Stockholder who so elects (a "Participating
Stockholder") shall have the right to transfer, at the same price and upon no
less favorable terms and conditions as the Transferring Stockholder, that number
of shares of Common Stock and/or Common- Equivalent Securities held by such
Participating Stockholder equal to (i) the number of shares of Common Stock
represented by the securities proposed to be transferred pursuant to the Tag-
Along Notice, multiplied by (ii) a fraction, the numerator of which is the
number of shares of Common Stock on a fully-diluted basis held by such
Participating Stockholder, and the denominator of which is the aggregate number
of shares of Common Stock on a fully-diluted basis held by the Transferring
Stockholder and all Participating Stockholders; provided, however, that the
price for any Common-Equivalent Securities to be transferred shall be net of any
unpaid exercise or conversion price associated therewith.

              (c) Within thirty (30) days after the date of delivery of a
Tag-Along Notice, any of the Stockholders may elect to participate in the
proposed transfer pursuant to the terms and conditions of such Tag-Along Notice
and this Agreement by delivery of a written notice to the Transferring
Stockholder. No Participating Stockholder shall be required to make any
representations and warranties to the third party purchaser or any other person
except as to good title and the absence of liens with respect to such
Stockholder's shares of Common Stock and/or Common-Equivalent Securities and the
authority for and the validity and binding effect of any agreements entered into
by such Stockholder in connection with such transfer.

              (d) The provisions of Section 3 shall not apply to (i) transfers
of Common Stock or Common-Equivalent Securities representing less than 10% of
the fully-diluted Common Stock, or (ii) transfers of Investor Stock to an
Investor or an Affiliate, officer or employee of an Investor.

         SECTION 4. Preemptive Rights.

              (a) In the event that any Common Stock or Common-Equivalent
Securities are issued by the Company other than an Excluded Issuance, each
Stockholder shall have the right to purchase its proportionate share of such
issuance in an amount equal to the number of shares of Common Stock or units of
Common-Equivalent Securities to be issued multiplied by a fraction (i) the
numerator of which is the number of shares of Common Stock on a fully-diluted
basis held by such Stockholder and (ii) the denominator of which is the total
number of shares of Common Stock outstanding on a fully-diluted basis prior to
giving effect to such issuance by the Company.

              (b) The Company shall give 30 days prior written notice to the
Stockholders of any issuance of Common Stock or Common-Equivalent Securities by
the Company. Each Stockholder shall have the right to purchase its proportionate
share of such issuance by giving written notice of its intention to exercise its
rights in accordance with Section 4(a) hereof, at a closing to be held no later
than 30 days after such Stockholder has received notice of the issuance from the
Company.

              SECTION 5. Drag-Along Rights. In the event that the Company's
Board of Directors approves a sale of the Company (pursuant to a merger or other
business combination transaction, sale of outstanding stock or otherwise) to a
third party not affiliated with either Investor (an "Approved Sale"), each
Stockholder shall consent to and raise no objections against such Approved Sale
(including exercising any statutory right of appraisal) and shall take all
necessary and desirable action in their capacities as stockholders of the
Company to facilitate such Approved Sale. If the Approved Sale is structured as
a sale of stock, the Stockholders shall agree to sell all of their shares of
Common Stock and Common-Equivalent Securities on the terms and conditions
approved by the Board of Directors; provided, however, that the obligations of
the Stockholders pursuant to this Section 5 are conditioned upon all
Stockholders concurrently receiving the same form and amount of consideration
per share of Common Stock pursuant to such Approved Sale or, if any Stockholders
are given an option as to the form and amount of consideration to be received,
all Stockholders are given the same option.

              SECTION 6. Tax Consolidation. From the date hereof, Cacomm hereby
agrees that it shall not make any federal, state or local tax filing on a
consolidated basis with the Company unless required by law. Cacomm further
agrees that it shall enter into a tax sharing agreement acceptable to the
Investors with respect to such consolidation upon the Investors' request.

              SECTION 7. Agreement Not to Compete.

              (a) Cacomm acknowledges and agrees that the value and goodwill of
the Company's business would be substantially impaired if Cacomm engaged in a
Competitive Business. Accordingly, Cacomm hereby agrees that until all of the
Preferred Stock has been redeemed by the Company, Cacomm shall not:

                                       5
<PAGE>

                   (i) engage in any Competitive Business at any location in the
              states between Maine and North Carolina, whether such engagement
              shall be as an employer, owner, employee, partner, advisor,
              consultant, stockholder or other participant in any Competitive
              Business (or in any similar capacity in which Cacomm derives an
              economic benefit from a Competitive Business);

                   (ii) assist others in engaging in any Competitive Business in
              the manner described in the foregoing clause (i);

                   (iii) solicit, entice or induce any employee of the Company
              or any subsidiary to terminate his or her employment or engage in
              any Competitive Business;

                   (iv) solicit, entice or induce any vendor, customer or
              distributor of the Company or any subsidiary to terminate or
              materially diminish its relationship with the Company or such
              subsidiary; or

                   (v) otherwise knowingly damage, disparage or interfere with
              the Company or any subsidiary;

provided, however, that (x) nothing contained in this Agreement shall prohibit
(i) Cacomm from owning in the aggregate less than 5% of a class of
publicly-traded securities issued by any Competitive Business or (ii) Cacomm
from maintaining its partnership interest in the Grand Alliance Partnership so
long as Cacomm does not affirmatively vote for, approve or assist the
partnership in a Competitive Business, (y) the provisions of this Section 7
shall expire in the event that the employment of Nicholas Mastrorilli, Sr. is
terminated by the Company without "Cause" (as defined in Mr. Mastrorilli's
employment agreement) upon the expiration of the period in which severance
payments are made by the Company to Mr. Mastrorilli, and (z) nothing in this
Agreement shall prohibit Cacomm from taking actions which, in the written
opinion of its counsel, are required in the exercise of fiduciary duties to the
stockholders of Cacomm not affiliated with Mr. Mastrorilli.

         (b) Cacomm acknowledges that a remedy at law for any breach or
threatened breach of the provisions of this Section 7 would be inadequate and
therefore agrees that the Company shall be entitled to injunctive relief;
provided, however, that nothing contained herein shall be construed as
prohibiting the Company from pursuing any other remedies available for any such
breach or threatened breach.

         SECTION 8. Restrictions on Transfer. A Non-Investor Stockholder shall
not sell, transfer, assign, pledge or encumber its stock of the Company or any
of its rights hereunder, except to a transferee (a) who or which, prior to such
sale, transfer, assignment, pledge or encumbrance, has executed an agreement to
be bound by all the provisions of this Agreement or (b) pursuant to a sale,
transfer or assignment (i) in compliance with Rule 144 or (ii) as part of a

                                       6

public offering of the stock of the Company pursuant to a registration statement
effective under the Securities Act.

         SECTION 9. Additional Shares of Stock. In the event additional shares
of stock are issued by the Company to any Stockholder or transferee thereof at
any time during the term of this Agreement, either directly or upon the
conversion, exercise or exchange of securities of the Company convertible into
or exercisable or exchangeable for shares of stock, such additional shares of
stock shall, as a condition to and effective upon such issuance, be subject to
the terms and provisions of this Agreement.

         SECTION 10. Legend on Stock Certificates. Each certificate representing
shares of stock held by the Stockholders shall bear a legend containing the
following words:

         "THE SALE, TRANSFER, ASSIGNMENT, PLEDGE OR ENCUMBRANCE OF THE
         SECURITIES REPRESENTED BY THIS CERTIFICATE AND/OR THE RIGHTS OF THE
         HOLDER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IN RESPECT OF

         COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST
         MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF
         MAGNAVISION CORPORATION."


         SECTION 11. Severability; Governing Law. If any provision of this
Agreement shall be determined to be illegal and unenforceable by any court of
law, the remaining provisions shall be severable and enforceable in accordance
with their terms. This Agreement shall be governed by, and construed in
accordance with, (a) the laws of the State of New York applicable to contracts
made and to be performed wholly therein and (b) the laws of the State of
Delaware with respect to corporations incorporated therein.

         SECTION 12. Successors and Assigns. This Agreement shall bind and inure
