Item 3.   Source and Amount of Funds and Other Consideration.

          Pursuant to an agreement dated October 21, 1994 among
the Company and the Purchasers named in that agreement (the "1994
Purchase Agreement") (attached to this statement as exhibit B and
incorporated by reference in this statement), the Fund purchased
from the Company 138,889 shares of 9% Series A Convertible Stock
(the "Original Series A Convertible Preferred Stock"), a warrant
(the "Original Antidilution Warrant") to purchase from the
Company, for $.01 a share, up to 1,491,000 shares of Common
Stock, and a warrant (the "Original Regular Warrant") to purchase
from the Company, for $2.25 a share (which was subsequently
reduced by amendment to $1.125 a share), up to 77,000 shares of
Common Stock, for an aggregate purchase price of $12,500,000,
which amount was paid to the Company from working capital of the
Fund.  On December 2, 1994, the Fund exercised the Original
Antidilution Warrant and, pursuant to the Original Antidilution
Warrant, purchased 1,491,000 shares of Common Stock for $14,467,
which amount was paid to the Company from working capital of the
Fund.  On January 5, 1995, the Fund exercised the Original
Regular Warrant, and, pursuant to the Original Regular Warrant,
as amended, purchased 77,000 shares of Common Stock for $86,625,
which amount was paid to the Company from working capital of the
Fund.

          Pursuant to agreements dated June 26, 1995 among the
Company and the Purchasers named in those agreements
(collectively, the "1995 Purchase Agreements") (attached to this
statement as exhibit C and incorporated by reference in this
statement), the Fund (a) purchased from the Company 100,000
shares of Series B-2 Convertible Preferred Stock, a warrant to
purchase from the Company, for $2.50 a share, up to 100,000
shares of Common Stock and a warrant (the "June Warrant") to
purchase from the Company, for $.01 a share, up to 428,571 shares
of Common Stock for an aggregate purchase price of $10,000,000,
which amount was paid to the Company from working capital of the
Fund, and (b) acquired 138,889 shares of Series A-1 Convertible
Preferred Stock in exchange for 138,889 shares of the Original
Series A Convertible Preferred Stock.  In connection with the
transactions contemplated by the 1995 Purchase Agreements, the
Fund received additional warrants to purchase from the Company,
for $1.79 a share, up to 100,000 shares of Common Stock.  On
December 29, 1995, the Fund exercised the June Warrant, and,
pursuant to the June Warrant, purchased 428,571 shares of Common
Stock for $4,285, which amount was paid to the Company from
working capital of the Fund.

Item 4.   Purpose of the Transaction.

          Pursuant to the 1994 Purchase Agreement and the 1995
Purchase Agreements, the Fund purchased the Regular Shares and
the Derivative Securities from the Company for investment
purposes.

          The Reporting Persons may make further purchases of
securities of the Company, and may dispose of such securities, at
any time.

          Pursuant to a letter agreement dated October 21, 1994
among the Purchasers under the 1994 Purchase Agreement and
Anthony J. Pompliano and Richard A. Kozak (collectively, the
"Managers") (the "Co-Sale Agreement") (attached to this statement
as exhibit D and incorporated by reference in this statement),
each Manager granted each Purchaser certain "tag-along" and
"first refusal" rights.  

          Pursuant to a stockholders agreement dated June 26,
1995 among the Company and the Stockholders named in that
agreement (the "June 1995 Stockholders Agreement") (attached to
this statement as exhibit E and incorporated by reference in this
statement), and subject to the limitations and qualifications set
forth in the June 1995 Stockholders Agreement, the parties agreed
that, if a Stockholder wished to sell any of his Stock (as
defined in the June 1995 Stockholders Agreement), he would give
the Company and the other Stockholders notice of that fact and
the terms on which he wished to sell his Stock; and, upon receipt
of that notice, the Company and the other Stockholders would have
the right to purchase that Stock on those terms.  The June 1995
Stockholders Agreement also provides that, if a Manager sold or
agreed to sell any Stock, he would cause the purchaser to whom he
was to sell the Stock to offer to purchase from each other
Stockholder, on the same terms, a proportionate quantity of the
other Stockholder's Stock.  In addition, the June 1995
Stockholders Agreement provides that, if holders of at least two-
thirds of the Series B Preferred Stock and at least two-thirds of
the Series A-1 Preferred Stock wished to sell at least two-thirds
of all the Stock to a third party, all the Stockholders would
sell or cause to be sold all their Stock to that third party on
the same terms and vote their Stock in favor of the transaction. 
The June 1995 Stockholders Agreement provides that it will
terminate on the earliest of a Qualifying Offering, a sale of the
Company or June 26, 2005.  The June 1995 Stockholders Agreement
also provides for the termination of the Co-Sale Agreement.

          Pursuant to a governance agreement dated November 8,
1995 among the Company and the Voting Shareholders named in that
agreement (the "November 1995 Governance Agreement") (attached to
this statement as exhibit F and incorporated by reference in this
statement), the parties agreed that, pending the adoption of the
Certificate of Designation Amendments (as defined in the November
1995 Governance Agreement) and subject to the limitations and
qualifications set forth in the November 1995 Governance
Agreement, (a) a "Triggering Event" would be the events or
transactions set forth in section 2(e) of the Certificate of
Designations Amendments, rather than the events or transactions
set forth in section 2(e) of the Current Certificate of
Designations (as defined in the November 1995 Governance
Agreement), (b) matters relating to the size, composition,
election and powers of the board of directors and the committees
of the board of directors of the Company would be governed by
section 6 of the Certificate of Designations Amendments, rather
than by section 6 of the Current Certificate of Designations, and
(c) the rights of the holders of Preferred Stock to vote as a
separate class on certain matters would be governed by section 7

terminate on the earliest of a Qualifying Offering, adoption of
the Certificate of Designations Amendments and six months after

1996, the stockholders of the Company approved the adoption of
the Certificate of Designations Amendments, which were thereafter
adopted.  On February 26, 1996, the November 1995 Governance
Agreement was amended (the "Supplement to the November 1995
Governance Agreement") (attached to this statement as exhibit G
and incorporated by reference in this statement) to reduce the
size of the board of directors from 11 to seven members, four of
whom are elected by holders of the Common Stock and three of whom
are elected by holders of the Preferred Stock.

1995 among the Voting Shareholders named in that agreement (the
"Voting Rights Agreement") (attached to this statement as exhibit
H and incorporated by reference in this statement), as amended on
December 14, 1995 (such amendment is attached to this statement
as exhibit I and incorporated by reference in this statement),
the Voting Shareholders agreed, subject to the limitations and
qualifications set forth in the Voting Rights Agreement, as
amended, (a) in any Election of Directors (as defined in the
Voting Rights Agreement, as amended), to vote their shares as set
forth in section 1 of the Voting Rights Agreement, as amended,
and (b) to use their best efforts to cause their respective
nominees to the board of directors of the Company to appoint
members to the compensation committee and the audit committee of
the board of directors of the Company as set forth in section 2
of the Voting Rights Agreement, as amended, and to cause the
board of directors of each subsidiary of the Company to be
composed as set forth in section 3 of the Voting Rights
Agreement, as amended.  The Voting Rights Agreement, as amended,
provides that it will terminate on the earliest of a Qualifying
Offering, the written agreement of the Fund and ING Equity
Partners, L.P. or November 8, 2005.

          Other than as set forth in this item 4, none of the
Reporting Persons has any plans or proposals that relate to, or
could result in, any of the matters referred to in paragraphs (a)
through (j), inclusive, of item 4 of Schedule 13D.  Such entities
and persons may, at any time and from time to time, review or
reconsider their position and formulate plans or proposals with
respect to their position, but have no present intention of doing
so.

any offer, issuance or sale of any securities under circumstances
that might require the integration of such securities with the
Series A Preferred Shares or the Warrants under the 1933 Act or
the rules and regulations of the Securities and Exchange
Commission (the "SEC")) that might subject the offering, issuance
or sale of the Series A Preferred Shares or the Warrants to the
registration provisions of the 1933 Act.

administrative expenses substantially as described in the
Business Plan (or to fund such other expenses as two-thirds of
the total number of Preferred Directors (as defined in the
Certificate of Resolution) may from time to time authorize (it
being understood that no such authorization shall be effective if
given at any time there is any vacancy among the Elected
Preferred Directors (as defined in the Certificate of
Resolution)).

          5.   General Post-Closing Covenants.  As long as any
Purchaser or any of its transferees in a private placement holds

unreasonably interfere with or disrupt the business in any
material respect.

          5.4  Triggering Events, Etc.  As long as any Series A
Preferred Shares are outstanding, the Company shall comply with
each provision of the Certificate of Resolution, and shall use
its best efforts not to cause, or suffer to exist or to continue

board of directors and shall cause the individual directors

          6.   Registration Rights

          6.1  Demand Registration.  Any time after June 30, 1995
(or, if sooner, upon shares being included in a registration
statement in accordance with any agreement listed on schedule
6.1), upon receipt of a notice (a "Demand Request") from
Purchasers and others identified on schedule 6.11.1 holding not
less than the Requisite Percentage of Registrable Shares
demanding the Company effect the registration under the 1933 Act
of any or all of their Registrable Shares, the Company shall file
a registration statement on a form to be selected by those making
the Demand Request (the "Demanding Shareholders") and effect the
registration under the 1933 Act of the Registrable Shares
specified in the Demand Request (a "Demand Registration").  The
Company shall be obligated to effect only three (four, if shares
are included in a registration statement in accordance with any
agreement listed on schedule 6.1) Demand Registrations using Form
S-1 (or its successor form(s)) ("Long-Form Demand
Registrations"), and shall not be obligated to effect any Demand
Registrations other than Long-Form Demand Registrations that are
made pursuant to Demand Requests made after the sixth anniversary
of the Closing Date; however, notwithstanding anything to the
contrary in this agreement, if, for any reason (other than the
fault of the Demanding Shareholders), a Long-Form Demand
Registration fails to become effective and to provide for the
distribution of all the Registrable Shares specified in the
Demand Request, or the effectiveness is not maintained for at
least 120 days in accordance with section 6.4 or the Company
fails to perform all its obligations under this section 6.1 with
respect to that Long-Form Demand Registration, the Demanding
Shareholders shall thereafter continue to be entitled to the same
number of Long-Form Demand Registrations in accordance with this
section 6.1 to which they had been entitled immediately before
the Demand Request that gave rise to that Long-Form Demand
Registration.  The holders of a majority of the Registrable
Shares making a particular Demand Request may, at their option,
elect (which election shall be included in the Demand Request) to
make the Demand Registration underwritten, in which event, and
subject to the rights of GKM under the agreement referred to on
schedule 3.2.24, the holders of a majority of the Registrable
Shares making the Demand Request shall be entitled to select the
underwriter(s).

          6.2  Piggyback Registration.  If at any time on or
before the 40th day following the sixth anniversary of the
Closing Date the Company determines or is requested or receives a
demand (pursuant to an agreement binding on the Company) from any
person or entity to register under the 1933 Act for sale to the
public any of the Company's securities on a form that also would
permit the registration under the 1933 Act for sale to the public
of any of the Registrable Shares held by a Purchaser, the Company
shall within 10 days thereafter give each Purchaser notice of its
intent to effect a registration, and, subject to sections 6.5 and
6.7, shall include in the registration all Registrable Shares
held by each Purchaser with respect to which the Company shall
have received a notice (a "Piggyback Request") specifying the
number of Registrable Shares to be included within 30 days after
the Company shall have given each Purchaser the notice pursuant
to this section 6.2.

          6.3  Obligation of Shareholder.  Any Demand Request or
Piggyback Request (a "Request") shall express the present intent
to offer for sale to the public the number of Registrable Shares
to be included in the registration statement and contain an
undertaking reasonably to provide such information and materials
and take such action as may be required to permit the Company to
comply with all applicable requirements of the SEC and to obtain
acceleration of the effective date of the registration statement.

          6.4  Obligations of the Company.  With respect to any
registration statement referred to in section 6.1 or 6.2, the
Company shall:

               (a)  use its best efforts to have the registration
statement declared effective as promptly as practicable, and in
any event within 120 days after the applicable Request, and shall
promptly notify each Purchaser, and such other persons as the
Purchaser designates, if any, and confirm such advice in writing,
(i) when the registration statement becomes effective, (ii) when
any post-effective amendment to the registration statement
becomes effective and (iii) of any request by the SEC for any
amendment or supplement to the registration statement or any
prospectus relating to the registration statement or for addi-
tional information;

               (b)  make available for inspection by any
underwriters participating in any planned disposition of
Registrable Shares and any attorney, accountant or other agent
retained by any Purchaser or the underwriters all financial and
other records reasonably necessary to permit them to demonstrate
that they have conducted a reasonable investigation of matters
described in the registration statement and cause the appropriate
Company officers to supply all such information reasonably
requested by each Purchaser, the underwriters or their agents;

               (c)  use reasonable efforts to qualify, not later
than the effective date of the registration statement, the
Registrable Shares under such "blue sky" or other state
securities laws as any Purchaser or underwriter may reasonably
request (it being understood, however, that the obligation under
this section 6.4(c) shall not obligate the Company to qualify as
a foreign corporation or a dealer in securities or to execute or
file any general consent to service of process under the law of
any such jurisdiction where it is not otherwise subject);

               (d)  furnish each Purchaser and any underwriter
such number of copies of the registration statement, each
amendment to the registration statement, the prospectus included
in each such registration statement and each amendment to each
registration statement, each amendment or supplement to any
prospectus and such other documents as the Purchaser and any
underwriter may request to facilitate the disposition of the
Registrable Shares;

               (e)  use best efforts to keep the registration
statement in effect and current for at least 120 days from the
effective date of the registration statement, and from time to
time to amend or supplement the registration statement or the
prospectus to the extent necessary to permit the completion of
the sale or distribution of the Registrable Shares within that
period in compliance with the 1933 Act.  If at any time the SEC
institutes or threatens to institute any proceeding for the
purpose of issuing a stop order suspending the effectiveness of
any such registration statement, the Company shall promptly
notify each Purchaser and use best efforts to prevent the
issuance of any such stop order or to obtain its withdrawal as
soon as possible.  The Company shall promptly advise each
Purchaser of any order or communication of any public board or
body addressed to the Company suspending or threatening to
suspend the qualification of any of the Registrable Shares for
sale in any jurisdiction; and

               (f)  insofar as the methods of distribution
proposed to be used are not reflected in the last prospectus
filed by the Company as part of the registration statement or
pursuant to Rule 424 under the 1933 Act, each Purchaser shall
promptly provide the Company with a description of the method or
methods of distribution of the Registrable Shares from time to
time contemplated by that Purchaser, and the Company shall file
any and all amendments and supplements necessary to include the
description in the registration statement.

          6.5  Conditions to the Obligations of the Company.  The
Company may postpone, for up to 90 days, the filing of any
registration statement otherwise required to be prepared and
filed by it under this agreement, if, at the time it receives a
Request, the Company would be required to prepare financial
statements other than those it customarily prepares or the
registration and offering would interfere with any material
financing, acquisition, corporate reorganization or other
material corporate transaction or development involving the
Company or any of its subsidiaries that is pending or imminent at
the time and promptly gives each Purchaser notice of that
determination (it being understood, however, that, in any such
event, the Company shall use best efforts to minimize the length
of the postponement).  If the Company shall so postpone the
filing of a registration statement, a Purchaser shall have the
right to withdraw its Request by giving written notice to the
Company within 30 days after the Company shall have given the
notice of postponement and, in the event of the withdrawal, the
Request that was withdrawn shall not be deemed to have been made.

          6.6  Expenses of Registration.  All expenses (excluding
underwriting or brokerage commissions attributable to the
Registrable Shares to be sold) incurred in connection with all
registrations under this agreement and the "blue sky" qualifica-
tions referred to in section 6.4(c), including, without limita-
tion, all registration and qualification fees, printers' and
accounting fees and fees and disbursements of counsel for the
Company, shall be borne by the Company.  Notwithstanding the
foregoing, however, in any registration under this section 6, the
Company shall be obligated to bear the fees or expenses of only
one counsel for the Purchasers (which counsel shall be selected
by the holders of a majority of the Registrable Shares making the
Demand Request, in the case of a Demand Request, or otherwise by
holders of a majority of the Registrable Shares included in the
registration), and shall not be required to bear any such fees or
expenses in respect of more than two (three, if shares are
included in a registration statement in accordance with any
agreement listed on schedule 6.1) Long-Form Demand Registrations.

          6.7  Underwriting Requirements.  In connection with any
offering pursuant to a Piggyback Request, the Company shall not
be required to register any Registrable Shares held by any
Purchaser, unless the Purchaser accepts the terms of the under-
writing and then only in such quantity as will not, in the
written opinion of the underwriters, exceed the maximum number of
Registrable Shares that can be marketed without materially and
adversely affecting the offering, if any, by the Company.  If, as
a consequence of the provisions of the preceding sentence, the
number of a particular Purchaser's Registrable Shares is reduced,
the percentage of reduction shall not be more than the percentage
of reduction applicable to any other Purchaser or any other
shareholder entitled to participate under any registration rights
agreement listed on schedule 3.2.11 and not listed on schedule
6.1.

          6.8  Other Registration Rights.  Without the prior
written consent of the Purchasers of a majority of the Series A
Preferred Shares, the Company shall not enter into any other
agreement entitling any person or entity to registration rights.

          6.9  Indemnification.  To the extent permitted by law,
the Company shall indemnify and hold harmless each underwriter,
if any, and each Purchaser that participates in any registration
under this agreement, and each person, if any, who is a director,
officer, agent, partner or shareholder of, or who controls
(within the meaning of Rule 12b-2 under the Securities Exchange
Act of 1934 (the "Exchange Act")), any such parties, against
losses, claims, damages and liabilities customarily indemnified
against in offerings and in accordance with the underwriter's
customary form.  Such indemnification shall include contribution
in the manner and to the extent customarily provided and in
accordance with the underwriter's customary form.  No Purchaser
in any such registration that relates to an underwritten offering
shall be required to make any representation or warranty to the
underwriter(s) or the Company, except as they relate solely to
that Purchaser and its method of distribution, and no such
Purchaser shall be liable under any underwriting agreement in an
aggregate amount greater than the net proceeds it receives in the
underwriting.

          6.10 Holdback.  At the request of holders of a majority
of the Registrable Shares then outstanding, each Purchaser shall,
and shall cause that Purchaser's transferees in private
placements to, agree with the underwriters in any underwritten
public offering of shares of capital stock of the Company not to
sell or otherwise dispose of any Registrable Shares for up to 180
days, in the case of the first public offering by the Company of
its shares of capital stock after the date of this agreement
pursuant to a registration statement under the 1933 Act, or up to
90 days, in the case of subsequent underwritten public offerings
by the Company of shares of its capital stock, after the
effective date of any registration statement covering any such
public offering.

          6.11  Definitions.  As used in this section 6, the
following terms have the following respective meanings:

          6.11.1  "Registrable Shares" means (a) the Series A
Preferred Shares, (b) the Warrants, (c) the shares of common
stock of the Company issuable upon conversion of the Series A
Preferred Shares and exercise of the Warrants and (d) the shares
of common stock issuable upon exercise of warrants issued to Huff
on September 27, 1994.

          6.11.2  "Requisite Percentage" means (a) in the case of
the first Long-Form Demand Registration, 40% of the total number
of shares of common stock of the Company constituting Registrable
Shares (including, for these purposes, the shares of common stock
of the Company issuable upon exercise or conversion of all
Registrable Shares) outstanding on the first day after the
closing under this agreement (such shares, the "Deemed
Outstanding Common Shares"), (b) in the case of subsequent Long-
Form Demand Registrations, 25% of the total number of Deemed
Outstanding Common Shares, and (c) in the case of all other
Demand Registrations, 10% of the total number of Deemed
Outstanding Common Shares.

          6.12  Registration Under Exchange Act.  Not later than
December 31, 1995, the Company shall register its common stock
under section 12 of the Exchange Act.  Thereafter, the Company
shall make all filings required of companies so registered, and
otherwise shall comply with the Exchange Act (it being understood
that this section 6.12 may be amended at any time by the
Purchasers of two-thirds of the Series A Preferred Shares).

          7.   Indemnification, Etc.  The Company shall indemnify
and hold each Purchaser and its affiliates and associates
(including, for these purposes, its partners, members, officers,
employees, representatives and other agents) harmless from and
against all losses, liabilities, damages and expenses (including
reasonable attorneys' fees and expenses) resulting from any
breach of warranty or agreement or any misrepresentation by the
Company under this agreement.  In the event of any breach of
warranty or misrepresentation in section 3.2.7, the Company shall
issue to each Purchaser that number of additional shares of the
Company's common stock that would have been required to be issued
to that Purchaser at the closing under this agreement to increase
that Purchaser's percentage of beneficial ownership of the
Company's common stock to the percentage that Purchaser would
then have beneficially owned had that representation or warranty
been correct, which adjustment shall be made by way of a
calculation of the type provided for in the first paragraph of
the Warrant issued to Huff hereunder, mutatis mutandis.  The
remedy provided in the immediately preceding sentence is in
addition to, and not in limitation of, any other rights or
remedies a Purchaser may have.

          8.   Miscellaneous

          8.1  Definition.  As used in this agreement, the term

Series A Preferred Shares and Warrants may not be sold,
transferred or otherwise disposed of without registration under
the 1933 Act or an applicable exemption from those registration
requirements.  Accordingly, as long as the sale of any Series A
Preferred Shares, or any shares of common stock issuable upon
conversion of those shares, held by a Purchaser or a Purchaser's
transferees is subject to such restrictions, each certificate
representing those shares shall bear a legend substantially as
follows:  "The shares represented by this certificate have not
been registered under the Securities Act of 1933 and may not be
transferred in violation of that Act or the rules and regulations
thereunder."

suit or proceeding relating to the Transaction Documents or any
such transaction except in such courts).  Each party further
agrees that service of any process, summons, notice or document
by U.S. registered mail to that party's address on schedule 1
shall be effective service of process for any action, suit or
proceeding in New York with respect to any matters to which it
has submitted to jurisdiction as set forth in the immediately

agrees not to plead or claim in any such action, suit or
proceeding brought in any such court that such action, suit or
proceeding has been brought in an inconvenient forum.

decree of specific performance, without posting any bond or
security.  The remedy provided in this section 8.8 is in addition
to, and not in lieu of, any other rights or remedies a party may
have.

          8.9  Separability.  If any provision of this agreement
is invalid or unenforceable, the balance of this agreement shall
remain in effect, and if any provision is inapplicable to any

obtain the consent of a Qualifying Holder before issuing any
press release or making any other public disclosure using that
Qualifying Holder's name or otherwise making reference to that
Qualifying Holder, unless the release or disclosure is required
to discharge the Company's legal obligations (in which case the
Company shall consult with that Qualifying Holder before issuing
the release or making the disclosure).

          8.12  Entire Agreement.  This agreement is the invest-
ment agreement dated October 19, 1994 referred to in the Certi-
ficate of Resolution.  This agreement and the other Transaction
Documents contain a complete statement of all the arrangements
among the parties with respect to their subject matter, supersede
all existing agreements among them with respect to that subject
matter, may not be changed or terminated orally and any amendment
or modification must be in writing and signed by the party to be

the employment or other relationship between that third party and
any of its consultants, employees or affiliates.  To the best
knowledge of the Company, no third party has requested
information from the Company which suggests that such a claim

person consulting or otherwise employed or affiliated with the
Company or any of its Subsidiaries has employed any trade secret
or any information or documentation proprietary to any former
employer, and no person consulting or otherwise employed or
affiliated with the Company or any of its Subsidiaries has

none of the execution or delivery of the Transaction Documents,
or the carrying on of the business of the Company as officers,
employees or agents by any officer, director or key employee of

with such agency's requirements under Environmental Laws
pertaining to the Company's or any of its Subsidiaries'

parties alleging any such noncompliance (a "Written Notice").

Company's registration statement dated February 13, 1995 on Form
SB-2, file number 33-87200, together with all amendments and
supplements thereto (the "Registration Statement"), did not,
contain any untrue statement of a material fact or omit to state
a material fact necessary to make the statements therein not
misleading (it being understood that nothing in this
representation is intended as a guarantee that any forecasted
results included in the Business Plan or the Registration
Statement will be realized).  The Registration Statement complies
in all material respects with the requirements of the 1993 Act
and all regulations promulgated thereunder.  There is no fact
which the Company has not disclosed to the Purchasers and their
counsel in writing and of which the Company is aware which
materially and adversely affects or, based on the best of the
knowledge of the Company given the facts and circumstances known
to the Company as of the date hereof, is likely to have a
material and adverse effect on the business, financial condition,
operations, property or affairs of the Company and its
Subsidiaries taken as a whole.  The financial projections and
other estimates delivered to the Purchasers were prepared by the
Company based on the Company's experience in the industry and on
assumptions of fact and opinion as to future events which the
Company, at the date of such delivery, believed to be reasonable,
but which the Company cannot and does not assure or guarantee the
attainment of in any manner.  As of the date hereof no facts have
come to the attention of the Company which would, in its opinion,
require the Company to revise or amplify the assumptions
underlying such projections and other estimates or the
conclusions derived therefrom.

          SECTION 3.2.23.  Offering and Approvals.  Neither the
Company nor any persons authorized or employed by it as agent,

for sale to, or solicited any offers to buy any such securities
from, or otherwise approached or negotiated with respect thereto
with, any person or persons other than the Purchasers or other
institutions and persons who are accredited investors (within the

any securities under circumstances that might require the
integration of such securities with the Series B Preferred Shares
or the Warrants under the 1933 Act or the rules and regulations
of the Securities and Exchange Commission (the "SEC") that might
subject the offering, issuance or sale of the Series B Preferred
Shares or the Warrants to the registration provisions of the 1933
Act.  Subject to the accuracy of the representationes and
warranties of the Purchasers set forth in Section 3.1.5, no
registration or filing with, or consent or approval of or other
action by, any Federal, state or other governmental agency or
instrumentality (including any applicable Federal Communications
Commission approval) is or will be necessary for the valid
execution, delivery and performance by the Company of the
Transaction Documents, the issuance, sale and delivery of the
Series B Preferred Shares and the Warrants, the issuance and
delivery of the shares of Common Stock upon the conversion of the
Series B Preferred Shares, or the issuance and delivery of the
Shares of Common Stock upon exercise of the Warrants, other than
(i) filings pursuant to state securities laws (all of which
filings have been made by the Company) in connection with the
sale of the Series B Preferred Shares and the Warrants and (ii)
with respect to the Registration Rights Agreement, the
registration of the shares covered thereby with the SEC and
filings pursuant to state securities laws.  Subject to the

contemplated hereby shall not violate any Federal, state or local
law or regulation, including any regulation of the Federal
Communications Commission.

          SECTION 3.2.25.  Leasehold Interests.  Each lease or
agreement to which the Company is a party under which it is a
lessee of any property, real or personal, is a valid and
subsisting agreement without any material default of the Company
thereunder and, to the best of the Company's knowledge, without
any material default thereunder of any other party thereto.  No
event has occurred and is continuing which, with due notice or
lapse of time or both, would constitute a default or event of
default by the Company under any such lease or Agreement or, to
the best of the Company's knowledge, by any other party thereto. 
The Company's possession of such property has not been disturbed
and, to the best of the Company's knowledge, no claim has been
asserted against the Company adverse to its rights in such
leasehold interests.

          SECTION 3.2.26.  Loans and Advances.  The Company does
not have any outstanding loans or advances to any person and is

otherwise invest in a debtor, or otherwise to assure a creditor
against loss), other than guaranties by the Company of
obligations of its Subsidiaries and except for guaranties by
endorsement of negotiable instruments for deposit or collection
in the ordinary course of business.

          SECTION 3.2.28.  Significant Customers and Suppliers. 
No customer which accounted for 10% or more of the Company's
sales during the period covered by the financial statements
referred to in Section 3.2.8 or which has been significant to the
Company thereafter, or supplier which is currently a sole source
supplier for one or more components necessary for the Company to
deliver its services has terminated, materially reduced or
threatened to terminate or materially reduce its purchases from
or provision of services to the Company, as the case may be.

          SECTION 3.2.29.  Further Equity Financing.  The Company
believes, as of the Closing Date, that, in the absence of changed
circumstances arising after the Closing Date, the net proceeds to
the Company from the sale of the Initial Shares, the Deferred
Shares and the Warrants pursuant to this Agreement, should be
sufficient so that the Company shall be able to proceed in
accordance with the Business Plan until March 31, 1996 without
the need to raise funds through placement, in return for cash, of
any series of capital stock of the Company or its Subsidiaries or
to grant any options, warrants or other rights to acquire any of
the capital stock of the Company or its Subsidiaries other than
in accordance with agreements existing as of the date hereof, the
AT&T Term Sheet or the Company's 1995 Stock Option Plan.

          SECTION 4.  Use of Proceeds.  The Company shall apply

tions system as described in the Business Plan, to fund selling,
general and administrative expenses substantially as described in

existing agreements or in the ordinary course of business, or
used to repurchase any securities of the Company or shall be paid
or used to make any payments to holders of securities of the
Company, except as listed on Schedule 4, without the prior
approval of each of the Series B Directors; provided, that, upon
the occurrence of a Governance Change Circumstance (as defined in
the Certificate of Designations), no such prior approval by the
Series B-1 Directors shall be required.  Notwithstanding the
foregoing, all expenditures to be paid with such proceeds must be
approved by the Preferred Directors prior to a commitment by the
Company to such expenditures, which approval may be granted
pursuant to the Board's approval of the Company's annual Budget. 
Notwithstanding any other provision of this Section 4, Section 4
shall not bar the Company from making payments under, and shall
not require approval by the Series B Directors of, agreements
that exist the date hereof, provided that such payments and
agreements are disclosed on Schedule 4 or another Schedule
attached hereto.

as set forth in Exhibit C before the stockholders of the Company

laws to be amended to read as set forth on Exhibit D.  The
Company shall, through its executive management and its board of
directors, recommend to the stockholders approval of the
amendment of the Charter to read in its entirety as set forth in
Exhibit C and ratification or adoption, as the case may be, of
amendments to the By-laws to read as set forth in Exhibit D at
such annual meeting; provided, however, that such recommendations
shall be subject to any action taken by the executive management
and board of directors of the Company in the exercise of good
faith judgment as to their respective fiduciary duties to the
stockholders of the Company, which judgment shall be based upon
the advice of independent counsel that a failure of the executive
management or board of directors, respectively, to withdraw or

stockholders of the Company shall have approved such proposed
amendments, the Company and the board of directors promptly shall
take all actions necessary to fully and validly approve and file
such amendment, to the extent required by law, with the Secretary

each party shall take such action and execute and deliver such
documents as the other may reasonably request to carry out the

          SECTION 7.6.  Fees and Expenses.  Except as otherwise

limited to, (i) the cost of reproducing the Transaction
Documents, (ii) the reasonable fees, expenses and disbursements
of the Purchasers' counsels, independent public accountants and

hereof, whether or not any such amendments, waivers or consents
are executed and (vi) reasonable fees and expenses incurred by
each Purchaser in any filing with any governmental agency with
respect to its investment in the Company or in any other filing
with any governmental agency with respect to the Company which
mentions such Purchaser; provided, however, that the Company will
pay at the Closing all such fees, expenses and costs incurred
prior to and through the Closing immediately upon receiving a
statement or invoice therefor.

          SECTION 7.7.  Counterparts.  This Agreement may be
executed in counterparts, each of which shall be considered an
original, but all of which together shall constitute the same
instrument.

          SECTION 7.8.  Equitable Relief.  The parties
acknowledge that the remedy at law for breach of this Agreement
may be inadequate and that, in addition to any other remedy a
party may have for a breach of this Agreement, that party may be
entitled to an injunction restraining any such breach or
threatened breach, or a decree of specific performance, without
posting any bond or security.  The remedy provided in this
Section 7.8 is in addition to, and not in lieu of, any other
rights or remedies a party may have.

          SECTION 7.9.  Separability.  If any provision of this
Agreement is invalid or unenforceable, the balance of this
Agreement shall remain in effect, and if any provision is
inapplicable to any person or circumstance, it shall nevertheless
remain applicable to all other persons and circumstances.

          SECTION 7.10.  Assignment.  Any Purchaser may assign
its rights under this Agreement, the Certificate of Designations
and the Charter (to the extent applicable) to any third party
that purchases from that Purchaser Series B Preferred Shares, the
Warrants or shares of Common Stock in a private placement and
agrees in writing to be bound by the provisions of this Agreement
as if that assignee were that Purchaser, except that a Qualifying
Holder may not assign its rights under Section 5.1(a), except to
a third party that purchases from that Purchaser in a private
placement at least 5,000 Series B Preferred Shares or Warrant(s)
to purchase at least 50,000 shares of Common Stock.

          SECTION 7.11.  Publicity.  The Company shall consult
with and obtain the consent of a Qualifying Holder before issuing
any press release or making any other public disclosure using
that Qualifying Holder's name or otherwise making reference to
that Qualifying Holder, unless the release or disclosure is
required to discharge the Company's legal obligations (in which
case the Company shall consult with that Qualifying Holder before
issuing the release or making the disclosure).

          SECTION 7.12.  Entire Agreement.  This Agreement is the
Series B Preferred Stock and Warrant Purchase Agreement dated
June 26, 1995 referred to in the Certificate of Designations. 
This Agreement contains a complete statement of all the
arrangements among the parties with respect to its subject
matter, supersedes all existing agreements among them with
respect to that subject matter.  Notwithstanding the foregoing,
the rights of the holders of Series A-1 Preferred Stock under the
Investment Agreement remain in effect, except as waived or
modified pursuant to the Stock Exchange Agreement described in
Section 6.23.

          SECTION 7.13.  Amendment and Modification; Waiver of
Compliance; Conflicts.

          (a)  This Agreement may be amended, modified or
terminated only by a written instrument duly executed by the
Company, Huff and ING.

          (b)  Except as otherwise provided in this Agreement,
any failure of any of the parties to comply with any obligation,
covenant, agreement or condition herein may be waived by the
party entitled to the benefits thereof only by a written
instrument signed by the party granting such waiver, but such
waiver or failure to insist upon strict compliance with such
obligation, covenant, agreement or condition shall not operate as
a waiver of, or estoppel with respect to, any subsequent or other
failure; provided that Huff and ING may effect any such waiver on
behalf of all of the Purchasers.

          (c)  In addition to the provisions of Section 7.13(b),
any failure of the Company to comply with any obligation,
covenant, agreement or condition herein may be waived by a
written instrument duly executed by a majority of the holders of
the Series A-1 Preferred Stock, but such waiver or failure to
insist upon strict compliance with such obligation, covenant,
agreement or condition shall not operate as a waiver of, or
estoppel with respect to, any subsequent or other failure.

          SECTION  7.14.  Further Issuances of Preferred Stock. 
Notwithstanding any other provision of this Agreement, the
Company may create and issue any securities that are pari passu
or junior to the Series A-1 Preferred Stock and the Series B
Preferred Stock, if the securities are issued at a conversion
price or an all-in effective price which is equal to or greater
than $2.50 (as appropriately adjusted to reflect all
Recapitalization Events, as defined in the Certificate of
Designations, occurring after the date hereof) per common share
equivalent and equal to or greater than the price which a
reputable investment banking firm acceptable to the board of
directors of the Company opines would be at least the minimum
price which would be fair from a financial point of view to the
Company and its stockholders in the context of the transaction. 
In connection with the creation or issuance of any such
securities, the parties agree to cooperate fully to enable the
Company to effect such creation or issuance, including, without
limitation, by voting in favor thereof in connection with any
amendment of the Certificate of Designations required for such
creation and issuance, by exchanging the securities issued
pursuant to this Agreement (including securities issued upon
conversion or exchange thereof) for new securities containing
substantially the same terms as such securities issued pursuant
to this Agreement and by amending this Agreement or any exhibit
to this Agreement as required for such creation and issuance (as
long as such amendment affects all parties, other than the
Company, similarly).

          SECTION 7.15.  Survival of Agreements.  All covenants,
agreements, representations and warranties made herein or in the
Registration Rights Agreement, the Stockholders Agreement, or any
certificate or instrument delivered to the Purchasers pursuant to
or in connection with this Agreement, the Registration Rights
Agreement or the Stockholders Agreement, shall survive the
execution and delivery of this Agreement, the Registration Rights
Agreement and the Stockholders Agreement, the issuance, sale and
delivery of the Series B Preferred Shares and Warrants, and the
issuance and delivery of the shares of Common Stock upon
conversion of the Series B Preferred Shares and upon exercise of
the Warrants, and all statements contained in any certificate or
other instrument delivered by the Company hereunder or thereunder
or in connection herewith or therewith shall be deemed to
constitute representations and warranties made by the Company.

          SECTION 7.16.  Brokerage.  Each party hereto will
indemnify and hold harmless the others against and in respect of
any claim for brokerage or other commissions relative to this
Agreement or to the transactions contemplated hereby, based in
any way on agreements, arrangements or understandings made by or
on behalf of such party with any third party.

          SECTION 7.17.  Counterparts.  This Agreement may be
executed in two or more counterparts, each of which shall be
deemed an original, but all of which together shall constitute
one and the same instrument.

          SECTION 7.18.  Titles and Subtitles.  The titles and
subtitles used in this Agreement are for convenience only and are
not to be considered in construing or interpreting any term or
provision of this Agreement.

          IN WITNESS WHEREOF, the Company and the Purchasers have
executed this Agreement as of the day and year first above
written.

does hereby transfer, assign, convey and deliver to the Company
the number of shares of Series A Preferred Stock set forth
opposite that Stockholder's name on Schedule 1.1, in exchange for

the Company of at least 227,500 shares of the Series B Preferred
Stock (the "Series B Preferred Stock Transaction") to the
purchasers thereof pursuant to that certain Series B Preferred
Stock and Warrant Purchase Agreement dated June 21, 1995 (the

to this Agreement have not been registered under the Securities
Act of 1933, as amended (the "Securities Act") or the securities
laws of any other jurisdiction and constitute "Restricted
Securities" within the meaning of Rule 144 under the Securities
Act and therefore may not be resold unless registered under the
Securities Act or sold pursuant to an exemption from such
registration.  The certificate(s) representing the Series A-1
Preferred Stock issued pursuant to this Agreement shall bear such
legend as the Company deems necessary or appropriate to comply
with the Securities Act and any other applicable federal and
state law.

Series A Stockholders (the "Series A Investment Agreement") and
the definitions of defined terms used in the Surviving Sections
but defined elsewhere in the Series A Investment Agreement shall
remain in full force and effect as if the shares of Series A-1
Preferred  Stock  issued to the Series A Stockholders hereunder
were issued and sold to the Series A Stockholders pursuant to the
Series A Investment Agreement at the time the shares of Series A
Preferred Stock purchased by the Series A Stockholders thereunder
were issued.  Except as provided in the preceding sentence, the
Series A Investment Agreement shall be deemed to be terminated

The Purchasers Under the
  Investment Agreement Dated
  October 21, 1994
c/o The Huff Alternative Income Fund, L.P.
30 Schuyler Place
Morristown, New Jersey  07960

Gentlemen:

          In order to induce you to consummate the closing under
the investment agreement dated October 21, 1994 among American
Communications Services, Inc. (the "Company") and you, the
undersigned agree as follows:

          1.   Co-Sale.  If, at any time prior to the
consummation of a Qualifying Offering (as defined in the
certificate of resolution relating to the Company's 9% Series A
Convertible Preferred Stock), either of the undersigned or any of
the undersigned's affiliates (as that term is used in the rules
and regulations under the Securities Exchange Act of 1934 (the
"Securities Rules")) or associates (as that term is used in the
Securities Rules) (collectively, the "Section 1 Seller") sells or
agrees to sell any shares of common stock of the Company
beneficially owned (as that term is used in the Securities Rules)
by him or them to someone other than the Company or any of its
subsidiaries, the Section 1 Seller shall cause the purchaser to
offer to purchase from each of you, at a price per share not less
than the price per share at which the Section 1 Seller shall have
sold or agreed to sell his shares and otherwise on the same terms
as those on which the Section 1 Seller shall have sold or agreed
to sell his shares, a number of shares equal to the fraction of
the number of shares of which you acquire beneficial ownership
under the Investment Agreement referred to above determined by
dividing the number of shares the Section 1 Seller is selling by
the total number of shares the Section 1 Seller beneficially owns
on the date of this letter agreement.

          2.   First Refusal.  If, at any time prior to the
consummation of a Qualifying Offering, either of the undersigned
or any of the undersigned's affiliates or associates
(collectively, the "Section 2 Seller") receives from a third
party, and wishes to accept, a bona fide offer to purchase shares
of common stock of the Company the Section 2 Seller beneficially
owns (but excluding shares acquired in open-market purchases
after the date of this letter agreement) (the "Offered Shares"),
the Section 2 Seller shall give notice to each of you (stating
the number of Offered Shares, the name and address of the offeror
and the terms and conditions of the offer) and you shall have the
option to purchase, on the same terms as those offered by the
third party, all (but not fewer than all) the Offered Shares (in
such proportions among you as you shall agree, or, absent an
agreement, in the proportions in which each of you that wishes to
purchase the Offered Shares acquires beneficial ownership of
shares of common stock of the Company under the Investment
Agreement referred to above).  This option shall be exercisable
by notice given to the Section 2 Seller within 10 days after the
date of receipt of the notice to each of you.  If you do not
exercise the option to purchase all the Offered Shares, at any
time within 60 days after the expiration of the option, the
Section 2 Seller may transfer all (but not fewer than all) the
Offered Shares to the third party offeror at the price and on the
terms and conditions stated in the offer (but, if the transfer to

     Agreement.  Prompt notice shall be given to the Company and
     each Stockholder by the transferor of any transfer (whether
     or not to a Permitted Transferee) of any Stock.

     (a)  Except for sales of securities contemplated by the
Registration Rights Agreement, dated the date hereof, among the
Company, the Series B Stockholders and the other parties named
therein (the "Registration Rights Agreement"), transfers
permitted by Sections 4.1 and 4.2 and transactions subject to
Section 5.7, if at any time any Stockholder shall desire to sell
any Stock owned by him or it (such Stockholder desiring to sell
shares of such Stock being referred to herein as a "Selling
Stockholder"), then such Selling Stockholder shall deliver
written notice of its desire to sell such Stock (a "Notice of
Intention"), accompanied by a copy of a proposal relating to such
sale (the "Sale Proposal"), to each of the other Stockholders and
to the Company, setting forth such Selling Stockholder's desire

proposed to be transferred (the "Offered Securities") and the
price at which and terms on which such Selling Stockholder
proposes to sell the Offered Securities (the "First Offer Price
and Terms") and other terms applicable thereto.

     (b)  Upon receipt of the Notice of Intention, the Company
and the other Stockholders shall then have the right to purchase
the First Offer Price and Terms and on the other terms specified
in the Sale Proposal all or, subject to Section 5.1(d), any
portion of the Offered Securities in the following order of
priority:  (i) if the Selling Stockholder is a Management
Stockholder, the other Management Stockholders shall have the

trustee by such Management Stockholders (or in such other
proportions as such Management Stockholders may agree), and
thereafter, the Preferred Stockholders shall have the right to
purchase the Offered Securities pro rata among the Preferred
Stockholders so electing to purchase on the basis of the
respective numbers of shares of Stock (with Preferred Stock

proportion as such Series A-1 Stockholders may agree), and
thereafter, the Series B Stockholders shall have the right to
purchase the Offered Securities pro rata among the Series B
Stockholders so electing to purchase on the basis of the

the right to purchase the Offered Securities; and (iii) if the
Selling Stockholder is a Series B Stockholder, the other Series B
Stockholders shall have the first right to purchase the Offered
Securities pro rata among those of the Series B Stockholders so

the right to purchase the Offered Securities.  The rights of the
Stockholders and the Company pursuant to this Section 5.1(b)
shall be exercisable by the delivery of notice to the Selling
Stockholder (the "Notice of Exercise"), within 30 calendar days
from the date of delivery of the Notice of Intention.  The Notice
of Exercise shall state the total number of shares of the Offered
Securities such Stockholder (or the Company) is willing to
purchase without regard to whether or not other Stockholders
purchase any shares of the Offered Securities.  A copy of such
Notice of Exercise shall also be delivered by each Stockholder to
the Company and each other Stockholder.  The rights of the
Stockholders and the Company pursuant to this Section 5.1(b)
shall terminate if unexercised 30 calendar days after the date of
delivery of the Notice of Intention.

     (c)  In the event that the Stockholders or the Company
exercise their rights to purchase any or all of the Offered
Securities in accordance with Section 5.1(b), then the Selling

the date of delivery of the Notice of Exercise received by the
Selling Stockholder.

Section 5.1, unless the Selling Stockholder shall have consented
to the purchase of less than all of the Offered Securities, no
Stockholder or Stockholders nor the Company may purchase any
Offered Securities hereunder unless all of the Offered Securities
are to be so purchased.

     (e)  For purposes of this Article V, any Person who has
failed to give notice of the election of any option hereunder
within the specified time period will be deemed to have waived
its rights on the day after the last day of such period.

     (f)  Each Stockholder in its capacity only as a stockholder
agrees and acknowledges that the Company may purchase or acquire
Common Stock pursuant to Section 5.1(b) hereof, and approves such
purchases and acquisitions, and waives any objection or claim
relating thereto, whether against the Company, the Board of
Directors or otherwise.

     Section 5.2.  Transfer of Offered Shares to Third Party.  If
all notices required to be given pursuant to Section 5.1 have
been duly given and the Stockholders and the Company do not
exercise their respective options to purchase all of the Offered
Securities at the First Offer Price and Terms and the Selling
Stockholder does not desire to sell less than all the Offered
Securities or if with the consent of the Selling Stockholder, the
other Stockholders and the Company purchase less than all of the
Offered Securities pursuant to the provisions hereof, then in
either such event the Selling Stockholder shall have the right,
subject to compliance by the Selling Stockholder with the
provisions to Section 4.3(b) hereof, for a period of 180 calendar
days from the earlier of (i) the expiration of the option period
pursuant to Section 5.1 with respect to such Sale Proposal or
(ii) the date on which such Selling Stockholder receives notice
from the other Stockholders and the Company that they will not
exercise in whole or in part the options granted pursuant to
Section 5.1, to enter into an agreement to sell, or to sell, to
any third party which is not an Affiliate of, or related to, the
Selling Stockholder the Offered Securities remaining unsold at a
price of not less than 90% of the First Offer Price and Terms,
and on the other terms no less favorable (taken as a whole) to
the purchaser than those specified in the Sale Proposal.

     Section 5.3.  Purchase of Offered Shares.  The consummation
of any purchase and sale pursuant to Section 5.1 shall take place
on such date, not later than 30 calendar days after the
expiration of the option period pursuant to Section 5.1 with
respect to such option, as the Selling Stockholder shall select. 
Prior to the consummation of any sale pursuant to Section 5.1,
the Selling Stockholder shall comply with Section 4.3(b) hereof. 
Upon the consummation of any such purchase and sale, the Selling
Stockholder shall deliver certificates evidencing the Offered
Securities sold duly endorsed, or accompanied by written
instruments of transfer in form satisfactory to the purchaser
duly executed by the Selling Stockholder free and clear of any
liens, against delivery of the First Offer Price and Terms,
payable in the manner specified in Section 5.1(a).

     Section 5.4.  Waiting Period with Respect to Subsequent
Transfers.  In the event that the Stockholders and the Company do
not exercise their options to purchase all of the Offered
Securities, and the Selling Stockholder shall not have sold the
remaining Offered Securities to a third party for any reason
before the expiration, as applicable, of the 180-day period
described in Section 5.2, then such Selling Stockholder shall not
give another Notice of Intention pursuant to Section 5.1 for a
period of 90 calendar days after the last day of such 180-day
period.

     Section 5.5.  Legally Binding Obligation.  Subject to
Section 5.1(a), making a written offer, giving or failing to give
written notice within the stated period, accepting an offer or
making a decision or election, in each case as provided in
Section 5.1 or 5.2, shall create a legally binding obligation to
buy or sell, or a legally binding obligation to refrain from
buying or selling, or a legally binding waiver of the right to
buy or sell, as the case may be, the subject Common Stock as
provided in such Section 5.1 or 5.2.

     Section 5.6.  Right to Join in Sale.

     (a)  Anything in this Agreement to the contrary
notwithstanding, if any Stockholder or group of Stockholders
proposes, other than transfers to a Permitted Transferee pursuant
to Section 4.2 (except for Section 4.2(b)), transactions subject
to Section 5.7 and transfers by any of ING, Huff, the First
Analysis Stockholders or their respective Affiliates or Permitted
Transferees, to sell, dispose of or otherwise transfer any Stock
(each a "Disposing Stockholder"), such person or group shall
refrain from effecting such transaction unless, prior to the
consummation thereof, each other Stockholder shall have been
afforded the opportunity to join in such sale of Common Stock on
a pro rata basis, as hereinafter provided.

     (b)  Prior to consummation of any proposed sale, disposition
or transfer of shares of Stock described in Section 5.6(a), the
Disposing Stockholder shall cause the person or group that
proposes to acquire such shares (the "Proposed Purchaser") to
offer (the "Purchase Offer") in writing to each other Stockholder
(collectively, the "Offerees") to purchase shares of Stock owned
by such Stockholder (regardless of whether the shares of Stock
proposed to be sold by the Disposing Stockholders are the same
class as the shares of Stock owned by such Stockholders), such
that the number of shares of such Stock so offered to be
purchased from such Stockholder shall be equal to the product
obtained by multiplying the total number of shares of such Stock
then owned by such Stockholder by a fraction, the numerator of
which is the aggregate number of shares of Stock proposed to be
purchased by the Proposed Purchaser from all Stockholders
(including the Disposing Stockholder or Stockholders) and the
denominator of which is the aggregate number of shares of Stock
then owned by all of the Offerees and the Disposing Stockholder,
in all cases considering Preferred Stock on an as if converted
basis.  Such purchase shall be made at the highest price per
share and on such other terms and conditions as the Proposed
Purchaser has offered to purchase shares of Stock to be sold by
the Disposing Stockholder or Stockholders, in all cases
considering Preferred Stock on an as if converted basis.  Each
Stockholder shall have 20 calendar days from the date of receipt
of the Purchase Offer in which to accept such Purchase Offer, and
the closing of such purchase shall occur within 30 calendar days
after such acceptance or at such other time as such Stockholder
and the Proposed Purchaser may agree.  The number of shares of
Stock to be sold to the Proposed Purchaser by the Disposing
Stockholder or Stockholders shall be reduced by the aggregate
number of shares of Stock purchased by the Proposed Purchaser
from the other Stockholders pursuant to the acceptance by them of
Purchase Offers in accordance with the provisions of this Section
5.6(b), considering Preferred Stock on an as if converted basis. 
In the event that a sale or other transfer subject to this
Section 5.6 is to be made to a Proposed Purchaser who is not a
Stockholder, the Disposing Stockholder shall notify the Proposed
Purchaser that the sale or other transfer is subject to this
Section 5.6 and shall ensure that no sale or other transfer is
consummated without the Proposed Purchaser first complying with
this Section 5.6.  It shall be the responsibility of each
Disposing Stockholder to determine whether any transaction to
which it is a party is subject to this Section 5.6.

     Section 5.7.  Take Along.  If at any time holders of at
least two-thirds of the Series B Preferred Stock and holders of
at least two-thirds of Series A-1 Preferred Stock (such Series
A-1 Stockholders and Series B Stockholders being referred to in
this Section 5.7 as the "Selling Stockholders") shall determine
to sell or exchange (in a business combination or otherwise) two-
thirds or more of their aggregate shares of Stock (considering
Preferred Stock on an as if converted basis) in a bona fide
arm's-length transaction to a third party in which the same price
per share shall be payable in respect of all shares of any class
of the Stock (considering Preferred Stock on an as if converted
basis), then, upon the written request of such Selling
Stockholders, each other Stockholder shall be obligated to, and
shall, if so requested by such third party, (a) sell, transfer
and deliver or cause to be sold, transferred and delivered to
such third party, all shares of Stock owned by them at the same
price per share and on the same terms as are applicable to the
Selling Stockholders (considering Preferred Stock on an as if
converted basis), and (b) if stockholder approval of the
transaction is required, vote his, her or its shares of Voting
Stock in favor thereof.  The provisions of Sections 5.1 through
5.4, inclusive, and Section 5.6 shall not apply to any
transactions to which this Section 5.7 applies.




                              ARTICLE VI

                              Termination

     (a)  The provisions of Articles II, III, IV and V shall
terminate on the date on which any of the following events first
occurs:  (i) a Qualifying Offering, (ii) a merger or
consolidation of the Company with or into another Person that is
being not an Affiliate of the Company, as a result of which the
Stockholders own less than 51% of the outstanding shares of
Voting Stock of the surviving or resulting corporation, or (iii)
ten years from the date of this Agreement; provided that the
provisions of Section 2.2 shall not terminate until all
accumulated or declared dividends with respect to all of the
Preferred Stock are paid in full and all amounts under any notes
issued pursuant to the terms of the Charter are paid in full.

     (b)  Notwithstanding the foregoing, this Agreement shall in
any event terminate with respect to any Stockholder when such
Stockholder no longer owns any Stock or warrants or options to
acquire Stock and no longer is due dividends with respect to
Preferred Stock or amounts under any notes issued pursuant to the
terms of the Charter, and shall terminate with respect to all
Stockholders upon the written consent of Huff and ING.

provided herein, all of the terms and provisions of this
Agreement shall be binding upon, inure to the benefit of and
shall be enforceable by the respective successors and assigns of
the parties hereto.  No Stockholder may assign any of its rights
hereunder to any Person other than a transferee that has complied
with the requirements of Sections 4.2 and 5.3 (if applicable) as
provided therein in all respects.  The Company may not assign any
of its rights hereunder to any Person other than its rights
hereunder to any Person other than an Affiliate of the Company. 
If any transferee of any Stockholder shall acquire any
Securities, in any manner, whether by operation of law or
otherwise, such shares shall be held subject to all of the terms
of this Agreement, and by taking and holding such shares such
Person shall be entitled to receive the benefits of and be
conclusively deemed to have agreed to be bound by and to comply
with all of the terms and provisions of this Agreement.

     Section 6.2.  Amendment and Modification; Waiver of
Compliance; Conflicts.

     (a)  This Agreement may be amended only by a written
instrument duly executed by (i) the holders of a majority of the
shares of the Series A-1 Preferred Stock, (ii) the holders of a
majority of the shares of the Series B Preferred Stock, and (iii)
to the extent that such proposed amendment would materially and
adversely affect the rights of the Management Stockholders under
this Agreement as a group, the holders of a majority of the
shares of Voting Stock owned by the Management Stockholders (it
being understood that any change requested by the managing
underwriter in a public offering would not be deemed to
materially and adversely affect the rights of the Management
Stockholders).  In the event of the amendment or modification of
this Agreement in accordance with its terms, the Stockholders
shall cause the Board of Directors of the Company to meet within
30 calendar days following such amendment or modification or as
soon thereafter as is practicable for the purpose of adopting any
amendment to the Charter and By-Laws of the Company that may be
required as a result of such amendment or modification to this
Agreement, and, if required, proposing such amendments to the
Stockholders entitled to vote thereon, and the Stockholders agree
to vote in favor of such amendments.

     (b)  Except as otherwise provided in this Agreement, any
failure of any of the parties to comply with any obligation,
covenant, agreement or condition herein may be waived by the
party entitled to the benefits thereof only by a written
instrument signed by the party granting such waiver, but such
waiver or failure to insist upon strict compliance with such
obligation, covenant, agreement or condition shall not operate as
a waiver of, or estoppel with respect to, any subsequent or other
failure.

     (c)  In addition to the provisions of Section 7.2(b), any
failure of the Company to comply with any obligation, covenant,
agreement or condition herein may be waived by a written
instrument duly executed by (i) the holders of a majority of the
shares of the Series A-1 Preferred Stock and (ii) the holders of
a majority of the shares of the Series B Preferred Stock, but
such waiver or failure to insist upon strict compliance with such
obligation, covenant, agreement or condition shall not operate as
a waiver of, or estoppel with respect to, any subsequent or other
failure.

     (d)  Notwithstanding the foregoing or any other provision of
this Agreement, the Company may create and issue any securities
that are pari passu or junior to the Series A-1 Preferred Stock
and the Series B Preferred Stock if the securities are issued at
a conversion price or an all-in effective price which is equal to
or greater than $2.50 (as appropriately adjusted to reflect all
Recapitalization Events, as defined in the Charter, occurring
after the date hereof) per common share equivalent and equal to
or greater than the price which a reputable investment banking
firm acceptable to the board of directors of the Company opines
would be at least the minimum price which would be fair from a
financial point of view to the Company and its stockholders in
the context of the transaction.  In connection with the creation
or issuance of any such securities, the parties agree to
cooperate fully to enable the Company to effect such creation or
issuance, including, without limitation, by voting in favor
thereof in connection with any amendment of the Certificate of
Designations required for such creation and issuance, by
exchanging the shares of Preferred Stock held by each such party
(including securities issued upon conversion or exchange thereof)
for new securities containing substantially the same terms as
such shares of Preferred Stock and by amending this Agreement as
required for such creation and issuance (as long as such
amendment affects all parties, other than the Company,
similarly).

document and other communication hereunder to any party shall be

     All such communications shall be deemed to have been given,
delivered or made when so delivered by hand or sent by telex
(answer back received) or telecopy, or five business days after

entire agreement among the parties hereto with respect to its
subject matter and supersedes all prior oral and written
agreements and memoranda and undertakings among the parties
hereto with regard to such subject matter.  The Company

                         GOVERNANCE AGREEMENT


       THIS GOVERNANCE AGREEMENT (this "Agreement"), dated as of
November 8, 1995, by and among American Communications Services,
Inc., a Delaware corporation (the "Company"), and certain holders
of the outstanding shares of 9% Series A-1 Convertible Preferred
Stock, $100 par value (the "Series A-1 Preferred Stock"), 9%
Series B-1 Convertible Preferred Stock, $1.00 par value, 9%
Series B-2 Convertible Preferred Stock, $1.00 par value and 9%
Series B-3 Convertible Preferred Stock, $1.00 par value
(collectively, the "Series B Preferred Stock" and together with
the Series A-1 Preferred Stock, the "Preferred Stock") of the
Company set forth in Schedule I hereto (collectively the "Voting
Shareholders").


                            R E C I T A L S

          WHEREAS, the Company's Certificate of Designations of
the Board of Directors relating to the Series A-1 Preferred Stock
and the Series B Preferred Stock filed with the Secretary of
State of the State of Delaware on June 26, 1995 (the "Current
Certificate of Designations") contains provisions relating to the
size, composition, election and powers of the Board of Directors
of the Company (the "Board") and certain separate class voting
rights for the holders of the Series A-1 Preferred Stock and
Series B Preferred Stock (the "Preferred Veto Rights");

          WHEREAS, The Nasdaq SmallCap Market ("NASDAQ") has
required that the foregoing provisions in the Current Certificate
be amended and restated in the manner set forth in Exhibit A (the
"Certificate of Designations Amendments") as a condition to the
Company's continued listing on NASDAQ; and

          WHEREAS, the Voting Shareholders deem it to be in their
best interests and the best interests of the Company for the
Company's listing on NASDAQ to be maintained; and

          WHEREAS, the Voting Shareholders deem it to be in their
best interests and the best interests of the Company to use all
reasonable efforts to cause the composition and election of the
Board and the Preferred Veto Rights to be consistent with the
Certificate of Designations Amendments until such time as such
amendments are approved by the stockholders of the Company,
notwithstanding any contrary provisions in the Current
Certificate of Designations; and

          WHEREAS, pursuant to the Certificate of Designations of
the Board of Directors relating to the 9% Series A Convertible
Preferred Stock (the "Series A Certificate") which was filed with
the Secretary of State of the State of Delaware on October 19,
1994 it is deemed that a Triggering Event (as such term was
defined in the Series A Certificate) would have occurred on or
prior to June 26, 1995, the date a Certificate of Elimination
relating to the Series A Certificate was filed with the Secretary
of State of the State of Delaware; and

          WHEREAS, pursuant to the Series A Certificate the
occurrence of a Triggering Event would have caused an increase in
the size of the Board of Directors from seven directors to 11
directors and result in the composition of the Board changing
from four directors elected by the holders of the Common Stock
and three directors elected by the holders of the Preferred Stock
to four directors elected by the holders of the Common Stock and
seven directors elected by the holders of the Preferred Stock;
and

          WHEREAS, under the Series A Certificate the Board would
have remained at 11 directors, with four elected by the holders
of the Common Stock and seven elected by the holders of the
Preferred Stock, for one year after all Triggering Events had
been cured; and

          WHEREAS, the aforementioned Triggering Event would have
been deemed to have been cured on June 26, 1995; and

          WHEREAS, the provisions regarding the size and
composition of the Board including upon the occurrence of a
Triggering Event, contained in the Certificate of Designations
Amendments are substantially similar to those set forth in the
Series A Certificate.

          NOW THEREFORE, in consideration of the foregoing and
for other good and valuable consideration, the parties hereto
hereby agree as follows:


     1.   Triggering Event.

          Until such time as the Certificate of Designations
Amendments are duly adopted by the stockholders of the Company
and filed with the Secretary of State of the State of Delaware
("Approval of the Certificate of Designations Amendments"),
notwithstanding any contrary provisions contained in the Current
Certificate of Designations, a Triggering Event shall be the
occurrence of any of the events or transactions set forth in
Section 2(e) of the Certificate of Designations Amendments,
rather than the occurrence of any of the events or transactions
set forth in Section 2(e) of the Current Certificate of
Designations.



     2.   Board of Directors.

          Until Approval of the Certificate of Designations
Amendments, notwithstanding any contrary provisions in the
Current Certificate of Designations, the parties agree that
matters relating to the size, composition, election and powers of
the Board and the Committees of the Board shall be governed by
the terms and provisions set forth in Section 6 of the
Certificate of Designations Amendments, rather than Section 6 of
the Current Certificate of Designations; provided that, until
June 26, 1996 (unless another Triggering Event occurs prior
thereto, in which case the applicable provisions of the
Certificate of Designations Amendments shall apply with respect
thereto), the Board shall consist of 11 directors, four of whom
will be elected by the holders of the Common Stock (the "Common
Directors") and seven of whom will be elected by the holders of
the Preferred Stock (the "Preferred Directors"); and provided
further, that on June 26, 1996 (unless another Triggering Event
shall have occurred prior thereto) the Board shall revert to
seven directors, four of whom will be Common Directors and three
of whom will be Preferred Directors.

     3.   Preferred Stockholder Veto Rights.

          Until approval of the Certificate of Designations
Amendments, notwithstanding any contrary provisions in the
Current Certificate of Designations, the parties agree that the
terms and provisions set forth in Section 7 of the Certificate of
Designations Amendments relating to the rights of the holders of
the Preferred Stock to vote as a separate class on certain
matters will govern the Company's obligation in this regard,
rather than the provisions of Section 7 of the Current
Certificate of Designations.

     4.   Further Assurances.

          The Voting Shareholders will use all reasonable efforts
and take all reasonable actions to enable the Company to be
governed by the terms and provisions of this Agreement.

                   _________________________________


          Anthony J. Pompliano, Chairman of the Board of
Directors of American Communications Services, Inc., a Delaware
corporation (the "Company"), certifies that the following
resolutions were (i) adopted by the Company's Board of Directors
by unanimous written consent dated November 7, 1995 pursuant to
DGCL 141 (f); (ii) approved by the holders of at least a majority
of the outstanding 9% Series A-1 Convertible Preferred Stock (the
"Series A-1 Preferred Stock"), voting as a separate class, at a

approved by the holders of at least a majority of the outstanding

called and held on ____________________; and (v) approved by the
holders of at least a majority of the outstanding common stock,
Series A-1 Preferred Stock and Series B Preferred Stock (as

meeting duly called and held on ____________________________:

          WHEREAS, pursuant to the Certificate of Designations of
the Board of Directors relating to the 9% Series A Convertible
Preferred Stock (the "Series A Certificate") which was filed with
the Secretary of State of the State of Delaware on October 19,
1994 a Triggering Event (as such term was defined in the Series A
Certificate) would be deemed to have occurred on or prior to June
26, 1995, the date a Certificate of Elimination relating to the
Series A Certificate was filed with the Secretary of State of the
State of Delaware; and

          WHEREAS, pursuant to the Series A Certificate the
occurrence of a Triggering Event would cause an increase in the
size of the Board of Directors from seven members to 11 members
and result in the composition of the Board changing from four
directors elected by the holders of the Common Stock and three
directors elected by the holders of the Preferred Stock to four
directors elected by the holders of the Common Stock and seven
directors elected by the holders of the Preferred Stock; and

          WHEREAS, under the Series A Certificate the Board of
Directors would remain at 11 members, with four elected by the
holders of the Common Stock and seven elected by the holders of
the Preferred Stock, for one year after all Triggering Events
have been cured; and

          WHEREAS, the aforementioned Triggering Event would be
deemed to have been cured on June 26, 1995; and

          WHEREAS, the provisions set forth in this Certificate
of Designations regarding the size and composition of the Board
of Directors, including upon the occurrence of a Triggering
Event, are substantially similar to those set forth in the Series
A Certificate; and

          WHEREAS, the Board of Directors will upon filing of
this Certificate of Designations be composed of 11 members, four
of whom were elected by the holders of the Common Stock or
designated by the directors elected by the holders of the Common
Stock and seven of whom were elected by the holders of Preferred
Stock; and

          WHEREAS, unless another Triggering Event (as defined in
this Certificate of Designation) occurs prior thereto the Board
of Directors will revert to seven members on June 25, 1996 and
the individuals who are currently serving on the Board of
Directors as Expansion Preferred Directors (as defined in this
Certificate of Designations) will cease to serve on the Board as
Preferred Directors at that time.

          RESOLVED, that the Company is authorized to issue
464,164 shares of convertible preferred stock, par value $1.00
per share, with such voting powers and such designations,
preferences and relative, participating, optional and other
special rights, and qualifications, limitations and restrictions
thereof, as follows:

          1.   Designation.  Of the preferred stock authorized by
this resolution, 186,664 shares shall be known as "9% Series A-1
Convertible Preferred Stock" ("the Series A-1 Preferred Stock"),
100,000 shares shall be known as "9% Series B-1 Convertible
Preferred Stock" (the "Series B-1 Preferred Stock"), 102,500
shares shall be known as "9% Series B-2 Convertible Preferred
Stock" (the "Series B-2 Preferred Stock"), 25,000 shares shall be
known as "9% Series B-3 Convertible Preferred Stock" (the "Series
B-3 Preferred Stock") and 50,000 shares shall be known as "9%
Series B-4 Convertible Preferred Stock" (the "Series B-4
Preferred Stock").  The Series B-1 Preferred Stock, the Series B-
2 Preferred Stock, the Series B-3 Preferred Stock and the Series
B-4 Preferred Stock are referred to herein collectively as the
"Series B Preferred Stock."  The Series A-1 Preferred Stock and
the Series B Preferred Stock are referred to herein collectively
as the "Preferred Stock".

          2.   Dividends.

          (a)  Amount.  The holders of shares of the Preferred
Stock shall be entitled to receive, when and as declared payable
by the board of directors from funds legally available for that
purpose, dividends in cash at the annual rate of (i) 9%, except
as provided in the following clause (ii), at all times, and (ii)
18%, (A) from and after January 1, 2000 and (B) at any time after
the occurrence and before the cure of a Triggering Event (as
defined in section 2(e)), of the Series A-1 Liquidation Value (as
defined in section 5) or the Series B Liquidation Value (as
defined in section 5), as the case may be, of those shares as of
the immediately preceding Dividend Payment Date (as defined
below) (or the date of issue, in the case of the initial Dividend
Payment Date), and no more, payable in equal amounts quarterly on
the last day of December, March, June and September in each year
(unless that day is not a business day (as defined in section
3(d)), in which event on the next business day) (each a "Dividend
Payment Date") to holders of record as they appear on the
register for the Preferred Stock on the December 15, March 15,
June 15 or September 15, respectively, immediately preceding the
Dividend Payment Date.

          (b)  Dividend Periods; Accumulation of Dividend.  A
quarterly dividend period shall begin on the day following each
Dividend Payment Date and end on the next succeeding Dividend
Payment Date.  Notwithstanding the foregoing, the first quarterly
dividend period with respect to each series of Preferred Stock
shall commence on the initial date of issue of such series and
end on the first Dividend Payment Date thereafter, and the
dividend for that period shall be determined on the basis of the
actual number of days in that period.  If dividends shall not
have been so paid upon all outstanding shares of Preferred Stock,
the deficiency shall be cumulative.  Notwithstanding the
foregoing, the initial date of issue of all of the shares of
Series A-1 Preferred Stock shall be deemed to be October 21,
1994; and the initial date of issue of all of the shares of
Series B-1 Preferred Stock, Series B-2 Preferred Stock and Series
B-3 Preferred Stock shall be deemed to be June 26, 1995.
Accumulated dividends shall, subject to section 2(c), be payable
in cash at any subsequent Dividend Payment Date, or, if earlier,
(i) at the time of conversion in accordance with section 3 or 4
or (ii) at the time stated and in accordance with section 2(c).

          (c)  Special Payment Provisions.  Notwithstanding
anything to the contrary in section 2(a) or 2(b), no dividends
shall be paid, or declared and set apart for payment, on or
before December 31, 1997, or, if earlier, at the time of
conversion in accordance with section 3 or 4. On January 1, 1998,
the Company shall, to the extent permitted by law, issue and
deliver to each holder a promissory note in the form of exhibit
2(c) hereto, executed by the Company and payable to the order of
the holder in the principal amount of that holder's accumulated
and accrued dividends.

          (d)  Dividend Priorities.  As to dividends, the Series
A-1 Preferred Stock and Series B Preferred Stock shall rank pari
passu with each other and shall rank senior to the common stock
from time to time created.  No dividend or distribution, whether
in cash, stock or other property, shall be paid, declared or set
apart for payment or made on or in respect of the common stock of
the Company, and, except pursuant to the agreements listed on
schedule 6.12(C) to the Series B Purchase Agreement (as defined
in section 2 (e)(iv)), no redemption, purchase or other
acquisition for value by the Company shall be made, or any funds
set apart for any sinking fund for such redemption, purchase or
other acquisition, of shares of common stock of the Company until
the earlier of a Qualifying Offering (as defined in section
4(a)(ii)) or January 1, 1998, and thereafter, unless all accrued
and unpaid dividends on all outstanding shares of Preferred
Stock, including without limitation any accrued and unpaid
dividends represented by any promissory note issued hereunder, to
the end of the quarterly dividend period coinciding with or next
preceding that date shall have been paid or declared and set
apart for payment; provided, however, that the foregoing
provisions of this sentence shall not prohibit a dividend on any
shares of any class or series of stock, which dividend is payable
in shares of any class or series of stock of the Company ranking
on a parity with or junior to the class or series of stock on
which the dividend is payable both as to dividends and as to any
distribution, including, without limitation, a distribution upon
liquidation, dissolution or winding-up of the Company.

          (e)  As used in this Certificate of Designations, the
term "Triggering Event" shall mean any of the following:

               (i)  the Company or any subsidiary shall have
failed to pay or prepay when due any principal, interest or
premium on any indebtedness for borrowed money after any
applicable cure period;

              (ii)  the Company or any subsidiary shall have
breached any of its other obligations in respect of any
indebtedness for borrowed money, or any condition shall have
existed, as a result of which any such indebtedness may, after
any applicable cure period, become or be declared due prior to
its stated maturity, and such breach or condition shall remain
uncured, unremedied or unwaived for 120 or more days after such
breach or condition;

             (iii)  there shall have been any material
misrepresentation or breach of warranty by the Company under the
investment agreement dated October 21, 1994 among the Company and
certain of the initial holders of the Company's 9% Series A
Convertible Preferred Stock, as amended by the Exchange Agreement
dated June 26, 1995 among the Company and the holders of the
Series A Preferred Stock as of such date (as may be amended from
time to time, the "Series A Investment Agreement");

              (iv)  there shall have been any material
misrepresentation or breach of warranty by the Company under the

June 26, 1995 among the Company and the initial holders of the
Series B Preferred Stock, (as may be amended from time to time,
the "Series B Purchase Agreement"), (B) Stockholders Agreement
dated June 26, 1995 among the holders of the Series A-1 Preferred
Stock, the holders of the Series B Preferred Stock and certain
holders of common stock, (as may be amended from time to time,
the "Stockholders Agreement), (C) Registration Rights Agreement
dated June 26, 1995 among the Company, the holders of the Series
A-1 Preferred Stock, the holders of the Series B Preferred Stock,
certain holders of the common stock and certain holders of
options or warrants convertible into common stock, (as may be
amended from time to time, the "Registration Rights Agreement"),
and (D) Governance Agreement dated as of November 8, 1995 among
the Company and certain holders of the Series A-1 Preferred
Stock, Series B Preferred Stock and Common Stock, (as may be
amended from time to time, the "Governance Agreement") that
remains uncured, unremedied or unwaived for 30 or more days after
such misrepresentation or breach;

               (v)  there shall have been any material breach of
any agreement by the Company under any of the Transaction
Documents (as defined in the Series A Investment Agreement) that
remain uncured for 30 or more days after the Company first has or
should have had actual knowledge of the breach;

              (vi)  there shall have been any material breach of
any agreement by the Company under any of the Transaction
Documents (as defined in the Series B Purchase Agreement) that
remains uncured for 30 or more days after the Company first has
or should have had actual knowledge of the breach;

             (vii)  The Company shall have failed to pay any
dividends on any outstanding shares of Preferred Stock when
payable hereunder whether pursuant to a promissory note issued
hereunder or otherwise and such failure shall remain uncured,
unremedied or unwaived for 30 or more days;

            (viii)  the Company shall have failed to comply with
any provisions of this Certificate of Designations of any other
provisions of its certificate of incorporation or by-laws
relating to the Preferred Stock, or the Company shall have
materially failed to comply with any other provisions of its
certificate of incorporation or by-laws, and such failure shall
remain uncured, unremedied or unwaived for 30 or more days after
such failure;

              (ix)  the Company and its subsidiaries shall have
failed by 20% or more to meet the major business milestones set
forth in schedule 5.15 to the Series B Purchase Agreement;

               (x)  a court of governmental authority of
competent jurisdiction shall have entered an order appointing,
without consent by the Company, a custodian, receiver, trustee or
other officer with similar powers with respect to it or with
respect to any substantial part of its property, or if an order
for relief shall have been entered in any case or proceeding for
liquidation or reorganization or otherwise to take advantage of
any insolvency law of any jurisdiction, or ordering the
dissolution, winding-up or liquidation of the Company or any
subsidiary, or if any petition for any such relief shall have
been filed against the Company or a subsidiary and such petition
shall not have been dismissed within 60 days; or

              (xi)  final judgment shall have been rendered
against the Company or any subsidiary for the payment of money in
excess of $250,000 and such judgment shall not have been

event of such a stay, such judgment is not discharged within 60
days after such stay expires.

          3.   Optional Conversion.  The holder of each
outstanding share of Preferred Stock shall have the right at any
time, or from time to time, at the holder's option to convert
that share into common stock in accordance with this section 3.

          (a)  Conversion Price.  (i)  Except as otherwise
provided in this section 3, each share of Series A-1 Preferred
Stock shall be convertible (at the office or agency referred to
in section 3(b)(i)) into a number of fully paid and nonassessable
shares (calculated as to each conversion to the nearest 1/10,000
of a share) of common stock equal to the number obtained by
dividing $90.00 by $2.25 ($2.25 being the "Series A-1 Conversion
Price") or, if the Series A-1 Conversion Price shall have been
adjusted in accordance with this section 3, by dividing $90.00 by
the Series A-1 Conversion Price as last adjusted and in effect at
the date any share or shares of Series A-1 Preferred Stock are
surrendered for conversion.  For purposes hereof the term "Series
A-1 Conversion Price" shall refer to the conversion price for the
Series A-1 Preferred Stock, as last adjusted pursuant to this
section 3.

              (ii)  Except as otherwise provided in this section
3, each share of Series B Preferred Stock shall be convertible

number of fully paid and nonassessable shares (calculated as to
each conversion to the nearest 1/10,000 of a share) of common
stock equal to the number obtained by dividing $100.00 by $2.80
($2.80 being the "Series B Conversion Price") or, if the Series B
Conversion Price shall have been adjusted in accordance with this
section 3, by dividing $100.00 by the Series B Conversion Price
as last adjusted and in effect at the date any share or shares of
Series B Preferred Stock are surrendered for conversion.  For
purposes hereof the term "Series B Conversion Price" shall refer
to the conversion price for the Series B Preferred Stock, as last
adjusted pursuant to this section 3.

          (b)  Procedures.

               (i)  To exercise the right to convert shares of
Preferred Stock into shares of common stock, the holder of the
shares of the Preferred Stock to be converted shall present and
surrender the certificate(s) representing the shares during usual
business hours at any office or agency of the Company maintained
for the transfer of the Preferred Stock and shall deliver a
written notice of the election of the holder to convert the
shares represented by that certificate or any portion of those
shares specified in that notice.  That notice also shall state
the name or names (with address(es)) in which the certificate or
certificates for shares of common stock issuable on conversion
shall be issued.  If so required by the Company, any certificate
for shares of Preferred Stock surrendered for conversion shall be
accompanied by instruments of transfer, in form reasonably
satisfactory to the Company, duly executed by the holder of the
shares surrendered for conversion or the holder's duly authorized
representative.  Each conversion of shares of Preferred Stock
shall be deemed to have been effected on the date (the
"conversion date") on which the certificate or certificates
representing the shares shall have been surrendered and that
written notice and any required instruments of transfer shall
have been so received, and the person or persons in whose name or
names any certificate or certificates for shares of common stock
shall be issuable on conversion shall be deemed to have become
the holder or holders of record of the shares of common stock
represented by the certificate or certificates immediately prior
to the close of business on the conversion date.

              (ii)  As promptly as practicable after the
presentation and surrender for conversion of any certificate for
shares of Preferred Stock, the Company shall issue and deliver to
or upon the written order of the holder of those shares a
certificate or certificates for the aggregate number of full
shares of common stock issuable upon conversion.  In case any
certificate for shares of Preferred Stock shall be surrendered
for conversion of only a portion of the shares represented by
that certificate, the Company shall deliver to or upon the
written order of the holder of those shares a certificate or
certificates for the number of shares of Series A-1 Preferred
Stock or Series B Preferred Stock, as the case may be,
represented by the surrendered certificate that are not being
converted.  The issuance of certificates for shares of common
stock issuable upon the conversion of shares of Preferred Stock
shall be made without charge to the converting holder for any tax
in respect of the issue of the shares of common stock.  The
Company shall not, however, be required to pay any tax that may
be payable based on the issue and delivery of any certificate in
a name other than that of the holder of the shares of Preferred
Stock being converted, and the Company shall not be required to
issue or deliver any such certificate, unless and until the
person requesting the issue shall have paid the Company the
amount of that tax or established to the reasonable satisfaction
of the Company that such tax has been paid or that no tax is due.

             (iii)  Upon any conversion of shares of Preferred
Stock into shares of common stock in accordance with this section
3 at any time on or before December 31, 1997, the Company shall
deliver to the holder, within three (3) business days after the
conversion date, in lieu of all accrued and unpaid dividends
through the conversion date on all shares to be converted, a
promissory note in the form of exhibit 3(b)(iii) hereto, executed
by the Company and payable to the order of that holder in the
principal amount of that holder's accumulated and accrued
dividends only those dividends shall be payable on shares of
common stock issuable upon conversion as may be declared and may
be payable to those entitled to be holders of record of shares of
common stock after that conversion date in accordance with
section 3(b)(i).

          (c)  Adjustment of Conversion Price Upon Issuance of
Common Stock.  Except as provided in section 3(c)(ix), if at any
time the Company shall issue, grant or sell, or is, in accordance
with section 3(c)(i) through (x), deemed to have issued, granted
or sold, any shares of common stock for a consideration per share
less than the Series A-1 Conversion Price or Series B Conversion
Price, as the case may be, in effect immediately prior to the
issuance, grant or sale (or, in the case of any pro rata
distribution to holders of the common stock of rights to
subscribe for the common stock or options, rights, warrants or
other securities convertible into or exchangeable or exercisable
for the common stock (a "Pro Rata Rights Offering"), the lesser
of such Conversion Price or the market price of the common stock
(as defined in section 3(d)) at that time), then, upon that
issuance, grant or sale, such Conversion Price shall be reduced
to the amount specified in the following clause (ww) (or, in the
case of Pro Rata Rights Offerings, the lesser of the following
clauses (ww) and (xx)):

               (ww)  in the case of the issuance, grant or
          sale, or deemed issuance, grant or sale, by the
          Company of shares of common stock for a
          consideration per share less than such Conversion
          Price, the price determined by dividing (1) an
          amount equal to the sum of (A) the number of
          shares of common stock outstanding immediately
          prior to that issuance, grant or sale (including
          as outstanding all shares of common stock issuable
          upon conversion of all outstanding shares of
          Preferred Stock for which the conversion price is
          being adjusted) multiplied by such Conversion
          Price then in effect, and (B) the consideration,
          if any, received by the Company upon that
          issuance, grant or sale, by (2) the total number
          of shares of common stock outstanding immediately
          after that issuance, grant or sale (including as
          outstanding all shares of common stock issuable
          upon conversion of all outstanding shares of
          Preferred Stock for which the conversion price is
          being adjusted); and

               (xx)  in the case of the issuance, grant or
          sale, or deemed issuance, grant or sale, by the
          Company of shares of common stock for a
          consideration per share less than the market price
          of the common stock, the price determined by
          multiplying such Conversion Price in effect
          immediately prior to that issuance, grant or sale
          by a fraction, (1) the numerator of which shall be
          the sum of (A) the number of shares of common
          stock outstanding immediately prior to that
          issuance, grant or sale (including as outstanding
          all shares of common stock issuable upon
          conversion of all outstanding shares of Preferred
          Stock for which the conversion price is being
          adjusted) multiplied by the market price of the
          common stock immediately prior to that issuance,
          grant or sale plus (B) the consideration, if any,
          received by the Company upon that issuance, grant
          or sale, and (2) the denominator of which shall be
          the total number of shares of common stock
          outstanding immediately after that issuance, grant
          or sale (including as outstanding all shares of
          common stock issuable upon conversion of all
          outstanding shares of Preferred Stock for which
          the conversion price is being adjusted) multiplied
          by the market price of the common stock
          immediately prior to that issuance, grant or sale.

          For purposes of this section 3(c), the following also
shall be applicable:

               (i)  Issuance of Rights or Options.  In case at
     any time the Company shall in any manner grant (whether
     directly or by assumption in a merger or otherwise) any
     rights to subscribe for or to purchase, or any options or
     warrants for the purchase of, common stock or any stock or
     securities convertible into or exchangeable for common stock
     (such rights, warrants or options being called "Options" and
     such convertible or exchangeable stock or securities being
     called "Convertible Securities"), whether or not such
     Options or the right to convert or exchange such Convertible
     Securities are immediately exercisable, and the price per
     share for which common stock is issuable upon the exercise
     of such Options or upon conversion or exchange of such
     Convertible Securities (determined by dividing (A) the total
     amount, if any, received or receivable by the Company as
     consideration for the granting of such Options, plus the
     minimum aggregate amount of additional consideration payable
     to the Company upon the exercise of such Options, plus, in
     the case of Convertible Securities, the minimum aggregate
     amount of additional consideration, if any, payable upon the
     conversion or exchange of such Convertible Securities, by
     (B) the total maximum number of shares of common stock
     issuable upon the exercise of such Options or upon the
     conversion or exchange of such Convertible Securities) shall
     be less than the Series A-1 Conversion Price or Series B
     Conversion Price, as the case may be, immediately prior to
     the granting of such Options, then the total maximum number
     of shares of common stock issuable upon the exercise of such
     Options or upon conversion or exchange of the total maximum
     number of such Convertible Securities issuable upon the
     exercise of such Options shall be deemed to have been issued
     for such price per share as of the date of the granting of
     such Options and thereafter shall be deemed to be
     outstanding, Except as otherwise provided in section
     3(c)(iii), no additional adjustment of such Conversion Price
     shall be made upon the actual issuance of such common stock
     upon exercise of such Options or upon conversion or exchange
     of such Convertible Securities.  Notwithstanding anything to
     the contrary in this section 3(c), the issuance of the
     Warrants (as defined in the Series A Investment Agreement)
     and the Warrants (as defined in the Series B Purchase
     Agreement) and any subsequent exercise of the Warrants (as
     defined in the Series A Investment Agreement) or the
     Warrants (as defined in the Series B Purchase Agreement)
     shall not affect either the Series A-1 Conversion Price or
     the Series B Conversion Price.  If, upon the expiration of
     such Options or rights to convert or exchange such
     Convertible Securities, such Options remain unexercised or
     such Convertible Securities remain unconverted or
     unexchanged, as the case may be, such Conversion Price shall
     again be adjusted as if such unexercised Options or
     unconverted or unexchanged Convertible Securities had not
     been granted.

              (ii)  Issuance of Convertible Securities.  In case
     the Company shall in any manner issue (whether directly or
     by assumption in a merger or otherwise), grant or sell any
     Convertible Securities, whether or not the rights to
     exchange or convert such Convertible Securities are
     immediately exercisable, and the price per share for which
     common stock is issuable upon such conversion or exchange
     (determined by dividing (A) the total amount received or
     receivable by the Company as consideration for the issuance,
     grant or sale of such Convertible Securities, plus the
     minimum aggregate amount of additional consideration, if
     any, payable to the Company upon the conversion or exchange
     of such Convertible Securities, by (B) the total maximum
     number of shares of common stock issuable upon the
     conversion or exchange of such Convertible Securities) shall
     be less than the Series A-1 Conversion Price or the Series B
     Conversion Price, as the case may be, immediately prior to
     the issuance, grant or sale, then the total maximum number
     of shares of common stock issuable upon conversion or
     exchange of such Convertible Securities shall be deemed to
     have been issued for such price per share as of the date of
     the issuance or sale of such Convertible Securities and
     thereafter shall be deemed to be outstanding; provided,
     however, that (Y) except as otherwise provided in section
     3(c)(iii), no additional adjustment of such Conversion Price
     shall be made upon the actual issuance of such common stock
     upon conversion or exchange of such Convertible Securities
     and (Z) if any such issuance, grant or sale of such
     Convertible Securities is made upon exercise of any Option
     to purchase any of the Convertible Securities for which
     adjustments of such Conversion Price have been or are to be
     made pursuant to other provisions of this section 3(c), no
     further adjustment of such Conversion Price shall be made by
     reason of the issuance, grant or sale.  If, upon the
     expiration of the right to convert or exchange such
     Convertible Securities, such Convertible Securities remain
     unconverted or unexchanged, as the case may be, such
     Conversion Price shall again be adjusted as if such
     unconverted or unexchanged Convertible Securities had not
     been issued, granted or sold.

             (iii)  Change in Option Price or Conversion Rate. 
     If the purchase price provided for in any Option referred to
     in section 3(c)(i), the additional consideration, if any,
     payable upon the conversion or exchange of any Convertible
     Securities referred to in section 3(c)(i) or (ii) or the
     rate at which any Convertible Securities referred to in
     section 3(c)(i) or (ii) are convertible into or exchangeable
     for common stock shall change at any time (other than under
     or by reason of provisions designed to protect against
     dilution), the Series A-1 Conversion Price or the Series B
     Conversion Price in effect at the time of that event shall
     be readjusted to the Series A-1 Conversion Price or the
     Series B Conversion Price, as the case may be, that would
     have been in effect at that time had such Options or
     Convertible Securities still outstanding provided for that
     changed purchase price, additional consideration or
     conversion rate, as the case may be, at the time initially
     granted, issued or sold.

              (iv)  Stock Dividends.  In case the Company shall
     declare a dividend or make any other distribution upon any
     stock of the Company payable in common stock, Options or
     Convertible Securities, any common stock, Options or
     Convertible Securities, as the case may be, issuable in
     payment of that dividend or distribution shall be deemed to
     have been issued, granted or sold without consideration and
     the Series A-1 Conversion Price and the Series B Conversion
     Price shall be adjusted accordingly under the provisions of
     this section 3(c).

               (v)  Consideration for Stock.  In case any shares
     of common stock, Options or Convertible Securities shall be
     issued, granted or sold for cash, the consideration received
     by the Company shall be deemed to be the amount received by
     the Company, without deduction of any expenses incurred or
     any underwriting commissions or concessions paid or allowed
     in connection with the issuance, grant or sale.  In case any
     shares of common stock, Options or Convertible Securities
     shall be issued, granted or sold for a consideration other
     than cash, the amount of the consideration other than cash
     received by the Company shall be deemed to be the fair
     market value of that consideration as determined in good
     faith by disinterested members of the board of directors of
     the Company (which shall consider, if the transaction
     involves, directly or indirectly, 2,000,000 or more shares
     of common stock, the opinion of a leading firm of investment
     bankers selected by a majority of the Preferred Directors
     (as defined in section 6(d)) and reasonably acceptable to
     the Company and whose reasonable fees and expenses shall be
     paid by the Company), without deduction of any expenses
     incurred or any underwriting commissions or concessions paid
     or allowed in connection with the issuance, grant or sale. 
     In case any Options shall be issued in connection with the
     issuance, grant or sale of other securities of the Company,
     together comprising one integral transaction in which the
     parties do not specifically allocate consideration to such
     Options, such Options shall be deemed to have been issued
     without consideration and the Conversion Price shall be
     adjusted accordingly under the provisions of this section
     3(c) .

              (vi)  Record Date.  In case the Company shall take
     a record of the holders of its common stock for the purpose
     of entitling them (A) to receive a dividend or other
     distribution payable in common stock, Options or Convertible
     Securities, or (B) to subscribe for or purchase common
     stock, Options or Convertible Securities, then, upon such
     issuance, grant or sale, that record date shall be deemed to
     be the date of the issuance, grant or sale of the shares of
     common stock deemed to have been issued, granted or sold
     upon the declaration of the dividend or the making of the
     other distribution or the date of the granting of the right
     of subscription or purchase, as the case may be.

             (vii)  Treasury Shares.  The number of shares of
     common stock outstanding at any given time shall not include
     shares owned or held by or for the account of the Company or
     any of its subsidiaries, and the disposition (other than to
     the Company or any of its subsidiaries) of any such shares
     shall be considered an issuance, grant or sale of common
     stock for purposes of this section 3(c).

            (viii)  Subdivision or Combination of Stock.  In case
     the Company shall at any time subdivide its outstanding
     shares of common stock into a greater number of shares (by
     way of dividend, split or otherwise), the Series A-1
     Conversion Price and the Series B Conversion Price in effect
     immediately prior to the subdivision shall be
     proportionately reduced, and in case the outstanding shares
     of common stock shall be combined into a smaller number of
     shares (by way of reverse split or otherwise) the Series A-1
     Conversion Price and the Series B Conversion Price in effect
     immediately prior to the combination shall be
     proportionately increased.

              (ix)  Certain Issues of Common Stock Excepted. 
     Notwithstanding anything to the contrary in this section
     3(c), the Company shall not be required to make any
     adjustment of the Series A-1 Conversion Price or Series B
     Conversion Price in case of (A) the issuance of shares of
     common stock upon conversion of shares of Preferred Stock,
     (B) the issuance of shares of common stock pursuant to
     Options and Convertible Securities outstanding on June 26,
     1995 or issuable pursuant to agreements which are effective
     on or before such date, and set forth on exhibit A to
     schedule 3.2.7 to the Series B Purchase Agreement, or (C)
     the issuance of up to an additional 750,000 shares of common
     stock (or the issuance of Options to purchase such shares)
     to employees or consultants of the Company and its
     subsidiaries as management or employee incentives (as
     approved by the board of directors to the extent so required
     pursuant to sections 6(d) and 7).

               (x)  Reorganization or Reclassification.  If any
     capital reorganization or reclassification of the capital
     stock of the Company shall be effected in such a way
     (including, without limitation, by way of consolidation or
     merger or a sale of all or substantially all its assets)
     that holders of common stock shall be entitled to receive
     stock, securities or assets with respect to or in exchange
     for common stock, then, as a condition of the reorganization
     or reclassification, lawful and adequate provisions shall be
     made whereby each holder of shares of Preferred Stock shall
     thereafter have the right to receive, in lieu of the shares
     of common stock of the Company theretofore receivable upon
     the conversion of such shares, such shares of stock,
     securities or assets as may be issued or payable with
     respect to or in exchange for a number of shares of common
     stock equal to the number of shares of common stock
     theretofore so receivable had the reorganization or
     reclassification not taken place, and in any such case
     appropriate provision shall be made with respect to the
     rights and interests of the holder to the end that the
     provision of this section 3 (including, without limitation,
     provisions for adjustment of the Series A-1 Conversion Price
     and Series B Conversion Price) shall thereafter be
     applicable, as nearly as may be, in relation to any shares
     of stock, securities or assets thereafter deliverable upon
     the exercise of those conversion rights.  In the event of a
     merger or consolidation of the Company as a result of which
     a greater or lesser number of shares of common stock of the
     surviving corporation are issuable to holders of common
     stock of the Company outstanding immediately prior to the
     merger or consolidation, the Series A-1 Conversion Price and
     Series B Conversion Price in effect immediately prior to the
     merger or consolidation shall be adjusted in the same manner
     as though there were a subdivision or combination of the
     outstanding shares of common stock of the Company in
     accordance with section 3(c)(viii).

              (xi)  Certain Distributions.  In the event that the
     Company shall make any distribution of its assets upon or
     with respect to the common stock that does not constitute a
     dividend payable out of earnings or any surplus legally
     available for dividends under the Delaware General
     Corporation Law and that distribution does not constitute a
     liquidation under section 5, the holder of each outstanding
     share of Preferred Stock shall, after the record date for
     that distribution or, in the absence of a record date, after
     the date of that distribution, receive, the amount of such
     assets (or, at the option of the Company, a sum equal to the
     value of such assets at the time of distribution as
     determined in good faith by the board of directors of the
     Company (which shall consider the opinion of a leading firm
     of investment bankers selected by a majority of the
     Preferred Directors and reasonably acceptable to the Company
     and whose reasonable fees and expenses shall be paid by the
     Company)) that would have been distributed to such holder if
     the holder had converted that share of Preferred Stock into
     common stock immediately prior to the record date for that
     distribution or, in the absence of a record date,
     immediately prior to the date of that distribution.

          (d)  Market Price of the Common Stock.  For all
purposes of this section 3 and section 4, the "market price of
the common stock" at any date shall be determined as follows: 
(i) if the common stock is publicly traded at the time of
determination, the average of the closing prices for the common
stock on all domestic securities exchanges on which such security
may at the time be listed (it being understood that, for these
purposes, the NASDAQ National Market System is deemed an
"exchange") or, if there have been no sales on any such exchange
on such day, the average of this highest bid and lowest asked
prices on all such exchanges at the end of such day, or, if on
any day such security is not so listed, the average of the
representative bid and asked prices quoted on the NASDAQ System
as of 4:00 p.m., New York time, on such day, or if on such day
such security is not quoted in the NASDAQ System, the average of
the highest bid and lowest asked prices on such day in the
domestic over-the-counter market as reported by the National
Quotation Bureau, Incorporated, or any similar successor
organization, in each such case averaged over a period of
twenty-one (21) days consisting of the day as of which "market
price of the common stock" is being determined and the twenty
(20) consecutive business days prior to such day (a "business
day" being a day that is not a legal holiday or other day on
which banking institutions or any national securities exchanges
are authorized by law or executive order to close); or (ii) if
the common stock is not publicly traded at the time of
determination then, solely for purposes of this section 3, the
fair value of the common stock as determined by the Company's
board of directors, taking into account their fiduciary duties
(including to the holders of the Preferred Stock as if
converted).

          (e)  Immaterial Adjustments.  Notwithstanding the
foregoing provisions of this section 3, (i) no adjustment in the
number of shares of common stock into which any share of
Preferred Stock is convertible shall be required, unless the
adjustment would require an increase or decrease in the number of
shares of at least 1% and (ii) no adjustment in either the Series
A-1 Conversion Price or Series B Conversion Price shall be
required, unless the adjustment would require an increase or
decrease of at least $.001 per share; provided, however, that any
adjustments that, by reason of this section 3(e), are not
required to be made shall be carried forward and taken into
account in any subsequent adjustment.  On any conversion date,
all adjustments so carried forward shall be made at the time of
such conversion.  All calculations under this section 3 shall be
made to the nearest $.001 or the nearest 1/10,000 of a share, as
the case may be.

          (f)  Notice of Adjustment.  Whenever any adjustment is
required in the shares into which any share of Preferred Stock is
convertible, the Company shall promptly (i) file with each office
or agency maintained by the Company for the transfer of Preferred
Stock a statement describing in reasonable detail the adjustment
and the method of calculation used (which, at the time of such
filing, shall be certified as correct by the Company's
independent accountants) and (ii) cause a notice of the
adjustment, setting forth the adjusted Series A-1 Conversion
Price or Series B Conversion Price, as the case may be, to be
mailed to the holders of record of shares of Preferred Stock at
their respective addresses on the books of the Company.

          (g)  No Rights After Conversion.  All shares of
Preferred Stock that shall have been surrendered for conversion
in accordance with this section 3 or section 4 shall no longer be
deemed to be outstanding and all rights with respect to those
shares, including the rights, if any, to receive notices and to
vote, shall cease, except for the right of the holders, subject
to the provisions of this section 3, to receive shares of common
stock upon the conversion and any accumulated and accrued but
unpaid dividends.


          (h)  Certain Notices.  In the event that:

               (i)  the Company shall take action to make any
          distribution to the holders of its common stock;

              (ii)  the Company shall take action to effect a Pro
          Rata Rights Offering;

             (iii)  the Company shall take action to accomplish
          any capital reorganization, or reclassification of the
          capital stock of the Company (other than a subdivision,
          split or combination of its common stock), or a
          consolidation or merger to which the Company is a party
          and for which approval of any stockholders of the
          Company is required, or the sale or transfer of all or
          substantially all the assets of the Company; or

              (iv)  the Company shall take action or attempt to
          take action to cause a voluntary or involuntary
          dissolution, liquidation or winding-up of the Company;

then the Company shall (A) in case of any such distribution or
Pro Rata Rights Offering, at least 30 days prior to the date or
expected date on which the books of the Company shall close or a
record shall be taken for the determination of holders entitled
to the distribution or rights, and (B) in the case of any such
reorganization, reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding-up, at least 30
days prior to the date or expected date when that event shall
take place (for the avoidance of doubt, it being understood that,
in each such case, the shares of Preferred Stock shall continue
to be convertible at any time during the applicable 30-day (or
longer) period), cause written notice thereof to be mailed to
each holder of shares of Preferred Stock at the holder's address
on the books of the Company.  Any notice under clause (A) also
shall specify the date or expected date on which the holders of
common stock shall be entitled to the distribution or rights, and
any notice under clause (B) also shall specify the date or
expected date on which the holders of common stock shall be
entitled to exchange their common stock for securities or other
property deliverable upon such reorganization, reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation
or winding-up.

          (i)  Common Stock.  For purposes of this section 3, the
term "common stock" shall mean (i) the class of stock designated
as the common stock of the Company on the date of this
Certificate of Designations or (ii) any other class of stock
resulting from successive changes or reclassifications of such
common stock consisting solely of changes in par value, or from
no par value to par value, or from par value to no par value.  If
at any time as a result of an adjustment pursuant to section 3(c)
a holder of shares of Preferred Stock thereafter surrendered for
conversion shall become entitled to receive any shares of the
Company other than shares of common stock, thereafter the number
of such other shares so receivable upon conversion of shares of
Preferred Stock shall be subject to adjustment from time to time
in a manner and on terms as nearly equivalent as practicable to
the provisions with respect to the common stock in section 3(c),
and the other provisions of this section 3 with respect to the
common stock shall apply on like terms to any such other shares.

          (j)  Fractions.  No fractional share of common stock,
or scrip representing a fractional share, shall be issued upon
the conversion of any Preferred Stock.  If more than one share of
Preferred Stock shall be surrendered for conversion at one time
by the same holder, the number of full shares of common stock
issuable upon conversion shall be computed on the basis of the
aggregate number of shares so surrendered.  If any fractional
interest in a share of common stock would be deliverable upon the
conversion of any shares of Preferred Stock, the Company shall
pay, in lieu of the fractional share, in cash that fraction of
the market price of the common stock on the business day
immediately preceding the conversion.

          (k)  Reserved Shares.  The Company shall at all times
reserve and keep available, free from preemptive rights, out of
its authorized but unissued stock, for the purpose of effecting
the conversion of the shares of Preferred Stock, a number of its
authorized shares of common stock sufficient to effect the
conversion of all outstanding shares of Preferred Stock into
common stock at any time; provided, however, that nothing in this
section 3(k) shall preclude the Company from satisfying its
obligations in respect of the conversion of shares by delivery of
shares of common stock then held in the treasury of the Company. 
The Company shall, from time to time, use its best efforts to
cause the authorized number of shares of common stock to be
increased, if the aggregate number of authorized shares of common
stock remaining unissued and the issued shares of common stock in
its treasury (other than any shares of common stock reserved for
issuance in any other connection) shall not be sufficient to
permit the conversion of all outstanding shares of Preferred
Stock into common stock.

          4.   Automatic Conversion

          (a)  General

               (i)  In the event the Company consummate a
Qualifying Offering, all outstanding shares of Preferred Stock
shall be converted into shares of common stock simultaneously
with the first closing of the Qualifying Offering, automatically
and without any further action by any person.  The number of
shares of common stock into which each share of Series A-1
Preferred Stock shall be converted shall be the number obtained
by dividing $90.00 by the Series A-1 Conversion Price then in
effect and the number of shares of common stock into which each
share of Series B Preferred Stock shall be converted shall be the
number obtained by dividing $100.00 by the Series B Conversion
Price then in effect.

              (ii)  As used in this Certificate of Designations,
the term "Qualifying Offering" means a fully-distributed, firm
commitment underwritten public offering of shares of common stock
of the Company registered under the Securities Act of 1933, (A)
in which (y) the gross proceeds to the Company (i.e., gross
proceeds without any deduction for expenses or for underwriting
commissions or concessions) are at least $15,000,000 and (z) the
initial price to the public per share of common stock is at least
$5.00, as appropriately adjusted to reflect all subdivisions,
splits, share dividends or combinations of the common stock or
any Pro Rata Rights Offering (any such subdivision, split, share
dividend, combination or Pro Rata Rights Offering, a
Recapitalization Event") occurring after the date of this
Certificate of Designations and (B) the result of which is the
inclusion of the common stock in the NASDAQ National Market
System or listing of the common stock on the New York Stock
Exchange.

             (iii)  Immediately after the conversion under this
section 4, the Company shall give a written notice of the
conversion (the "Automatic Conversion Notice") to all the former
holders of record of shares of Preferred Stock at their
respective addresses on the books of the Company.  The Automatic
Conversion Notice shall set forth the instructions for effecting
the exchange of certificates, which shall be as nearly the same
as practicable as under section 3, the terms of which (including,
without limitation, sections 3(g) and 3(j)) are, except as
otherwise expressly provided in this section 4, incorporated in
this section 4, mutatis mutandis.

              (iv)  Notwithstanding anything to the contrary in
this section 4(a) and except as provided in section 3(c)(xi), no
dividend or other distribution of any nature whatsoever payable
in respect of the common stock after the conversion under this
section 4 shall be paid (but shall accrue) to a holder of any
unsurrendered certificate evidencing shares of Preferred Stock,
unless the certificate or certificates evidencing the holder's
shares of Preferred Stock so converted are delivered to the
Company in accordance with the Automatic Conversion Notice or the
holder notifies the Company that the certificate or certificates
have been lost, stolen or destroyed and executes an agreement
reasonably satisfactory to the Company to indemnify the Company
against any resulting loss it incurs.  Thereupon, (A) there shall
be issued and delivered to the holder, in the holder's name shown
on the certificate or certificates, a certificate or certificates
evidencing the number of shares of common stock into which the
holder's shares of Preferred Stock were converted (together with
any cash payment in lieu of a fractional share) and (B) the
holder shall be entitled to payment of the amount referred to in
the immediately preceding sentence.

          (b)  Notwithstanding anything to the contrary in this
Certificate of Designations, upon any conversion of shares of
Preferred Stock into shares of common stock pursuant to this
section 4, the Company shall pay, on the conversion date, all
accumulated and accrued but unpaid dividends in cash; provided,
however, that if, in connection with the Qualifying Offering, the
underwriter advises the Company in writing that such payment
would materially and adversely affect the Qualifying Offering, in
lieu of the immediate payment of such accumulated and accrued but
unpaid dividends to the holder, the Company shall, within 30 days
after delivering the Automatic Conversion Notice, (i) pay the
holder its pro rata share, based upon the aggregate amount of
accumulated and accrued but unpaid dividends owed by the Company
to all holders of Preferred Stock and the amount of such
dividends owed to such holder, the greatest of (A) the amount the
underwriter advises would not so affect the Qualifying Offering,
(B) 5% of the net proceeds to the Company of the Qualifying
Offering (i.e., gross proceeds less deductions for all expenses
and underwriting commissions and concessions), but not more than
all accumulated and accrued but unpaid dividends, or (C) 10% of
the then accumulated and accrued but unpaid dividends, and (ii)
issue and deliver to each holder a promissory note in the form of
exhibit 4(b) hereto, executed by the Company and payable to the
order of that holder in the principal amount of the balance of
that holder's accumulated and accrued dividends; provided that,
at the option of such holder and in lieu of the receipt of such a
promissory note in the form of exhibit 4(b) hereto, such holder
may elect, by written notice delivered to the Company no later
than 20 days after the Company's delivery of the Automatic
Conversion Notice, to receive the number of shares of common
stock equal to the principal amount of such note divided by the
initial price to the public per share of the common stock sold in
the Qualifying Offering.  A certificate representing such shares
of common stock shall be delivered by the Company to such holder
as soon as practicable after the Company's receipt of such
holder's election to receive such shares of common stock, but in
no event later than 20 days after such receipt.

          (c)  Any note issued pursuant to sections 2(c),
3(b)(iii) or 4(b) may be converted at any time prior to payment
in full thereof, at the option of the holder of such note, by
written notice given to the Company by such holder, into the
number of shares of common stock equal to (i) the sum of the then
outstanding principal amount of such note and any accrued
interest thereon, divided by (ii) the market price of the common
stock as of the date notice of such election is given by such
holder; provided, however, that if such notice is given within 20
business days after consummation of the Qualifying Offering, the
number of shares of common stock to be issued hereunder shall be
determined by dividing the amount determined under clause (i) by
the initial price to the public per share of the common stock
sold in the Qualifying Offering.  A certificate representing such
shares of common stock shall be delivered by the Company to such
holder as soon as practicable after the Company's receipt of such
holder's election to receive such shares of common stock and the
Company's receipt and cancellation of such note, but in no event
later than 20 days after receipt of such election and note.

          5.   Liquidation.  In the event of any liquidation,
dissolution or winding-up of the Company, whether voluntary or
involuntary, the holders of outstanding shares of Preferred Stock
shall be entitled to receive for each such share payment in cash
equal to the sum of (a) $90.00 in the case of Series A-1
Preferred Stock (the "Series A-1 Liquidation Value") and $100.00
in the case of the Series B Preferred Stock (the "Series B
Liquidation Value"), plus in each case an amount equal to all
accrued but unpaid dividends (but excluding accumulated
dividends) to the date of payment, or final payment, if there is
more than one payment (the "Series A-1 Liquidation Value", the
"Series B Liquidation Value", and the amount of such accrued and
unpaid dividends shall collectively constitute the "Liquidation
Value"), plus (b) an amount (the "Accumulated Dividend Amount")
equal to all accumulated but unpaid dividends to the Dividend
Payment Date immediately preceding the date of payment or final
payment, as the case may be, and no more.  As to distribution
upon liquidation, dissolution or winding-up, the Series A-1
Preferred Stock and Series B Preferred Stock shall rank pari
passu with each other and shall rank senior to the common stock
of the Company.  An amount equal to the sum of the Liquidation
Value plus the Accumulated Dividend Amount shall be paid to the
holders of Preferred Stock before any payment or distribution
shall be made to the holders of shares of common stock of the
Company.  The voluntary sale, conveyance, lease, exchange or
transfer of all or substantially all the assets of the Company
(unless, in connection therewith, the liquidation, dissolution or
winding-up of the Company is specifically approved), or the
merger or consolidation of the Company into or with any other
corporation, or the merger of any other corporation into it, or
any purchase or redemption of shares of stock of the Company of
any class or series, shall not be deemed to be a liquidation,
dissolution or winding-up of the Company for purposes of this
section 5.  Nothing in this section 5 shall be deemed to limit in
any way the right of the holders of shares of Preferred Stock to
convert any or all of those shares at any time before or
simultaneously with the payment to all those holders in respect
of those shares of an amount equal to the Liquidation Value plus
the Accumulated Dividend Amount in respect of all those shares. 
After the distributions described above have been paid, the
remaining assets of the Company available for distribution to
stockholders shall be distributed among the holders of the
Preferred Stock, any other series or class of preferred stock
entitled to a share of the remaining assets of the Company and
common stock pro rata based on the number of shares of common
stock held by each (assuming full conversion of all such
Preferred Stock or such other series or class of preferred
stock).

          6.   Voting; Governance.

          (a)  General.  Except as otherwise provided in this
section 6 and in section 7 or as required by law, the holders of
Preferred Stock shall vote with the holders of common stock (and
any other series or class of preferred stock entitled to so vote)
as a single class and shall be entitled to one vote for each
share of common stock into which the shares of Preferred Stock so
held would be convertible on the record date for the vote of
stockholders.

          (b)  Board of Directors.

               (i)  Subject to section 6(b)(ii), the board of
directors of the Company shall have seven members, of which the
holders of shares of common stock shall have the right to elect
four and the holders of shares of Preferred Stock shall have the
right to elect three (the directors so elected by the holders of
the Preferred Stock, the "Elected Preferred Directors").

              (ii)  Upon the occurrence of a Triggering Event,
(A) the board of directors shall be increased to 11 members, (B)
the newly created directorships resulting from that increase
shall be filled by individuals elected by the holders of
Preferred Stock (those so elected, the "Expansion Preferred
Directors") and (C) the board of directors shall continue to have
11 members, of which holders of shares of common stock shall have
the right to elect four, and of which holders of shares of
Preferred Stock shall have the right to elect three Elected
Preferred Directors and, until the first anniversary of the cure
of the Triggering Event the occurrence of which gave rise to the
provisions of this subparagraph (ii), four Expansion Preferred
Directors.  One year after all Triggering Events shall have been
cured, the board of directors shall be reduced to seven directors
and the Expansion Preferred Directors shall cease to be
directors.  Notwithstanding the foregoing the occurrence of the
Triggering Events in Section 2(e)(iv) or 2(e)(vi) shall not cause
the increase in the size of the board of directors or the other
foregoing provisions of this Section 6(b)(ii) to be implemented.

          (c)  Procedures

               (i)  Each director of the Company shall hold
office for a term expiring at the next annual meeting of
stockholders.  Any vacancy caused by the death or resignation of
a Preferred Director may be filled only by the holders of
Preferred Stock entitled to vote for such Preferred Director.  A
special meeting of the holders of the Preferred Stock entitled to
vote with respect to filling the vacancy shall be called and held
as promptly as practicable after any such death or resignation at
the direction of a majority of the board of directors, and in any
event shall be called within ten days, to be held within 15 days,
after receipt of a written request by the holders of record of at
least 50% of the then outstanding shares of Preferred Stock so
entitled to vote.  In connection with any special meeting to be
held for the purpose of electing a Preferred Director to fill a
vacancy, only such holders of the Preferred Stock entitled to
vote for such Preferred Director shall be notified and be
permitted to participate at such meeting.  If any special meeting
of the holders of Preferred Stock required to be called for the
election of directors pursuant to this section 6(c) shall not
have been called within ten days after the request therefor has
been made upon the secretary of the Company, the holders of
record of at least 50% of the then outstanding shares of the
Preferred Stock so entitled to vote may designate in writing one
of their number to call the meeting, and the meeting may be
called by the person so designated upon notice in accordance with
the notice required for annual meetings of stockholders.  Any
holder of shares of Preferred Stock so designated shall have
access to the stock record books of the Company for the purpose
of so calling a special meeting.  The Company shall pay the
reasonable expenses of calling and holding any such meeting.

              (ii)  Any special meeting of the holders of shares
of Preferred Stock to vote for the election of directors pursuant
to this section 6(c) shall be held in the city in which the next
preceding annual meeting of stockholders of the Company was held. 
At a special or annual meeting for the election of directors by
the holders of shares of Preferred Stock, the presence in person
or by proxy of the holders of 50% of the outstanding shares of
Preferred Stock entitled to vote thereon shall constitute a
quorum.  In connection with any special meeting to be held for
the purpose of electing a Preferred Director to fill a vacancy,
only such holders of the Preferred Stock entitled to vote for
such Preferred Director shall be notified and be permitted to
participate at such meeting.  A majority of the holders of the
shares of Preferred Stock entitled to vote thereon present in
person or by proxy shall have the power to adjourn the meeting
for the purpose of such election, from time to time without
notice, other than announcement at the meeting, until a quorum
shall be present.

             (iii)  In connection with any vote for the Preferred
Directors, each holder of Preferred Stock entitled to vote
thereon as provided herein shall be entitled to one vote per
share, and the nominees receiving a plurality of the votes
entitled to be cast shall be elected.

          (d)  Certain Major Decisions.  The board of directors
of the Company shall act by majority vote of the directors with
any interested parties in affiliated transactions being recused
(that is, by a majority of the disinterested directors in
accordance with Section 144 of the DGCL).  Each director shall
have one vote on all matters to be voted upon by the board of
directors.  In determining the presence of a quorum at all
meetings of the board of directors, a quorum shall consist of a
majority of the total number of directors.  Notwithstanding the
foregoing, the unanimous consent of the Elected Preferred
Directors and if there are any Expansion Preferred Directors then
on the Board, the consent of six-sevenths (6/7's) of the total
number of the Elected Preferred Directors and Expansion Preferred
Directors, if any (collectively, the "Preferred Directors"),
shall be required to approve any action specified in section 7
and, in addition, any of the following (it being understood that,
notwithstanding anything to the contrary in this certificate, no
such action may be approved at any time there is any vacancy
among the Elected Preferred Directors):

               (i)  disposition or encumbrance of a material
portion of the assets or business of the Company or any of its
subsidiaries, including, for these purposes, any sale of
securities of any of the Company's subsidiaries, affiliates or
joint ventures (by the Company or any such entities), except as
set forth in Schedule 3.2.7 to the Series B Purchase Agreement;

              (ii)  formation of any joint venture, partnership
or other business combination by the Company or any of its

             (iii)  expenditures by the Company or any subsidiary
in a single transaction or a series of related transactions in
excess of $500,000, or commitments to make any such expenditures;

              (iv)  dividends or distributions, whether in cash
or otherwise, in respect of the Company's common stock, or any
redemption, purchase or other acquisition of any capital stock of
the Company (or securities convertible into or exchangeable for
such capital stock) or authorization, issuance or grant of any
securities of the Company or any subsidiary, other than the put
rights referred to in Schedule 3.2.7 to the Series B Purchase
Agreement;

               (v)  selection of an underwriter or placement
agent of any financing involving the Company's or its
subsidiaries, securities;

              (vi)  establishment of any committees of the board
of directors (other than the compensation and audit committees);

             (vii)  any transaction with an affiliate or an
associate of the Company or any subsidiary (other than a direct
or indirect wholly-owned subsidiary of the Company) (it being
understood that the transactions contemplated by this clause
(vii) do not include compensation and benefit arrangements with
employees, subject to section 6(d)(ix)), except those
transactions contemplated by the Series B Purchase Agreement or
set forth on Schedule 3.2.20 to the Series B Purchase Agreement;

            (viii)  incurrence by the Company or any subsidiary
of any indebtedness for borrowed money (in addition to
indebtedness outstanding on the date of this certificate),
including obligations under capital leases, or guarantees of any
such indebtedness of another person or entity, or the issuance of
any securities of the Company or any subsidiary, except for the
financing referred to in Schedule 3.2.9 to the Series B Purchase
Agreement;

              (ix)  change the compensation or benefits to any
officer, director or employee of the Company or any subsidiary
from the amounts in effect at June 26, 1995;

               (x)  any amendment or other change in any
insurance policy covering the Company or any subsidiary on the
date of this certificate, or any change in the identity of any
insurer;

              (xi)  except as set forth on Schedule 3.2.11 to the
Series B Purchase Agreement any leasehold commitment involving
consideration or a liability, contingent or otherwise, in excess
of $50,000 in the aggregate;

             (xii)  any change in the accounting policies or
procedures of the Company or any subsidiary or any change in the
Company's independent accountants;

            (xiii)  any other transaction or series or related
transactions which any party's total commitments and obligations
exceed $50,000; and

             (xiv)  any change in the Business Plan (as defined
in the Series B Purchase Agreement), including, without
limitation, the Company or any subsidiary, directly or indirectly
through an affiliate or joint venture, entering into any line of
business other than as contemplated by the Business Plan, or the
acquisition or creation of any other business or entity.

          (e)  Certain Committees.

               (i)  the board of directors shall establish and
maintain a compensation committee comprised of three directors,
none of whom may be an employee of the Company or any of its
subsidiaries and two of whom shall be Preferred Directors
selected by a majority of the Preferred Directors.  The
compensation committee shall be responsible for recommending to
the full board of directors all stock option grants, bonuses and
other compensation arrangements for executives and key employees
and loans and other non-salary payments and other benefits and
arrangements with employees and affiliates and associates of the
Company.  The compensation committee shall have such additional
powers and duties as the board of directors from time to time
determines.

              (ii)  The board of directors shall establish and
maintain an audit committee comprised of three directors, one of
whom shall be a senior executive officer of the Company (but not
the chief financial or chief accounting officer) and two of whom
may not be employees of the Company or any of its subsidiaries,
and shall be Preferred Directors selected by a majority of the
Preferred Directors.  The audit committee shall be responsible
for selecting the Company's independent auditors and reviewing
their audit, as well as reviewing and approving the Company's
internal controls and accounting systems.  The audit committee
shall have such additional powers and duties as the board of
directors from time to time determines.

             (iii)  In the event that the group of directors of
the Company that are specified to select a committee member
pursuant to section 6(f)(i) or 6(f)(ii) is deadlocked over its
selection of such committee member for more than 30 days, the
full board of directors shall select such committee member from
among such group of directors.

          (f)  Certain Expenses.  The Company shall from time to
time pay (i) all reasonable out-of-pocket expenses incurred by
directors in attending meetings of the board of directors and its
committees, and (ii) the reasonable fees and expenses of two
counsel(s) selected by the Preferred Directors from time to time
to represent them as such; that counsel may, at the Preferred
Directors' election, attend any meeting of the board of directors
or any committee that includes a Preferred Director.

          7.  Class Voting Upon Certain Events.  In addition to
such other vote, if any, as may be required by law or provided by
this Certificate of Designations, the consent of the holders of
at least 75% of the shares of the Preferred Stock at the time
outstanding, voting together as a single class, given at a
meeting (or by a written consent in lieu of a meeting) shall be
necessary for effecting or validating each of the following:

          (a)  authorization or creation of any other class or
series of stock, if such class or series ranks, or any series
thereof could rank, prior to or on a parity with any of the
Preferred Stock;

          (b)  amendment, alteration, waiver or repeal of the
provisions of the certificate of incorporation of the Company
(including this certificate) or the by-laws of the Company (for
the avoidance of doubt, it being understood that holders of at
least 75% of the shares of Preferred Stock at the time
outstanding, voting together as a single class, may effect or
validate any amendment of this Certificate of Designations
(including any amendment that changes the provisions of section 3
or 4) and may waive any provision of this Certificate of
Designations and may consent to any action or inaction that
would, in the absence of such consent, violate this Certificate
of Designations or constitute a Triggering Event);

          (c)  merger, consolidation or other business
combination of the Company with or into any other corporation or
recapitalization of the Company; or

          (d)  sale of all or substantially all the assets of the
Company.

          8.  Preemptive Rights.  If, at any time prior to a
Qualified Offering, the Company proposes to issue any securities
to any person or entity (other than pro rata issuances of
securities to all holders of common stock, issuances of Options
to employees and issuances of common stock pursuant to Options
and Convertible Securities described on schedule 3.2.7 to the
Series B Purchase Agreement) (a "Proposed Issuance"), each holder
of shares of Preferred Stock or common stock issued upon
conversion thereof shall have the right (which the holder may
exercise in whole or in part) to purchase, upon the same terms, a
proportionate quantity of those securities in the proportion that
the aggregate number of shares of common stock (assuming exercise
of all Warrants (as defined in the Series A Investment Agreement
and that certain Note Purchase Agreement (the "Note Purchase
Agreement") dated as of June 28, 1994 relating to the Company's
15% Convertible Notes due December 31, 1994) and Warrants (as
defined in the Series B Purchase Agreement) and conversion of all
Preferred Stock) then beneficially owned (as that term is used in
the rules and regulations under the Securities Exchange Act of
1934) and that were acquired under either the Series A Investment
Agreement, the Series B Purchase Agreement or the Exchange
Agreement by that party bears to the total number of shares of
common stock (assuming exercise of all Warrants (as defined in
the Series B Purchase Agreement, Series A Investment Agreement
and Note Purchase Agreement)) and conversion of all Preferred
Stock) of the Company then beneficially owned and that were
acquired under such Investment Agreement, Exchange Agreement and
Purchase Agreement by all holders of shares of Preferred Stock or
common stock issued upon conversion thereof.  The Company shall
give notice to each holder setting forth the identity of the
proposed purchaser and the time, which shall not be fewer than 45
days and not more than 60 days, within which, and the terms upon
which, each holder may elect, by written notice given to the
Company in accordance with the Company's notice to each holder,
to purchase the securities, which terms shall be the same as the
terms upon which the proposed purchaser may purchase the
securities.  If there is any change in any terms of the Proposed
Issuance, the holders shall have no further rights with respect
to that Proposed Issuance, and the provisions of this section 8
shall again apply to the Proposed Issuance, as so changed, as if
the Proposed Issuance, as so changed, were being proposed
initially as the Proposed Issuance.  If any holder (a "Shortfall
Purchaser") wishes to purchase a quantity of securities greater
than the holder's proportionate quantity and any other holder
wishes to purchase fewer than that holder's proportionate
quantity of securities (a "Shortfall"), the Shortfall Purchaser
may (in accordance with an election that may be made pursuant to
the Company's notice to each holder) elect to purchase any or all
of the aggregate amount of all the Shortfalls in the proportion
that the amount of Shortfalls specified by the Shortfall
Purchaser in the election to purchase securities bears to the
aggregate amount of all the Shortfalls specified by all Shortfall
Purchasers in all the election to purchase securities.  Any
securities not purchased by the holders of shares of Preferred
Stock under this section 8 may thereafter be sold to the proposed
purchaser at any time within 90 days after the expiration of that
45- or 60-day period on the same terms as those upon which
holders of shares of Preferred Stock were entitled to purchase
the securities.

          9.  Retirement of Shares.  Shares of Preferred Stock
that are converted into shares of common stock as provided in
this Certificate of Designations or otherwise acquired by the
Company in any manner shall be permanently retired and shall not
under any circumstances be reissued.  The Company shall from time
to time take such appropriate corporate action as may be
necessary to reduce the authorized Preferred Stock accordingly.

          10.  Increase or Decrease in Shares of the Series. 
Subject to the provisions of sections 6 and 7, the board of
directors is authorized to adopt, from time to time, a resolution
or resolutions providing for an increase or decrease in the
number of shares constituting Series A-1 Preferred Stock or
Series B Preferred Stock, but no such decrease shall reduce at
any time the number of shares of Preferred Stock at the time
outstanding.

          11.  Transfer Agent, Conversion Agent and Registrar. 
The Company shall, as long as any shares of Preferred Stock are
outstanding, maintain an office or agency where the shares may be
presented for registration of transfer and exchange and for
conversion.

          12.  Governmental Approvals; Listing.  If any shares of
common stock that would be issuable upon conversion of shares of
Preferred Stock require registration with or approval of any
governmental authority before the shares may be issued upon
conversion, the Company shall use its best efforts as
expeditiously as possible to cause the shares to be duly
registered or approved, as the case may be.  The Company shall
endeavor to list the shares of (or depository shares representing

installments, together with all accrued interest on the principal
amount from time to time outstanding to the date of payment, on

may not be resold unless registered under the Securities Act or
sold pursuant to an exemption from such registration and (ii) the
certificate(s) representing the shares of common stock of the
Borrower so received shall bear such legend as the Company deems
necessary or appropriate to comply with the Securities Act and

                   SUPPLEMENTAL GOVERNANCE AGREEMENT


          THIS SUPPLEMENTAL GOVERNANCE AGREEMENT (this
"Agreement"), dated as of February 26, 1996, by and among

                            R E C I T A L S

          WHEREAS, on November 8, 1995, in response to voting

Company and the Voting Shareholders entered into a Governance
Agreement (the "Governance Agreement") pursuant to which, among
other things, the Voting Shareholders agree to cause the
composition and election of the Board of Directors and the
Preferred Veto Rights to be consistent with the Certificate of
Designations Amendments until such time as such amendments were
approved by the stockholders of the Company, notwithstanding any
contrary provisions in the Current Certificate of Designations;
and

          WHEREAS, pursuant to the Governance Agreement, it was
deemed that a Triggering Event (as such term was defined in the
Series A Certificate) would have occurred on or prior to June 26,
1995, the date a Certificate of Elimination relating to the
Series A Certificate was filed with the Secretary of State of the
State of Delaware; and

          WHEREAS, pursuant to the Series A Certificate the
occurrence of a Triggering Event would have caused an increase in
the size of the Board of Directors from seven directors to 11
directors and resulted in the composition of the Board changing
from four directors elected by the holders of the Common Stock
and three directors elected by the holders of the Preferred Stock
to four directors elected by the holders of the Common Stock and
seven directors elected by the holders of the Preferred Stock;
and 

          WHEREAS, under the Series A Certificate the Board would
have remained at 11 directors, with four elected by the holders
of the Common Stock and seven elected by the holders of the
Preferred Stock, for one year after all Triggering Events had
been cured; and

          WHEREAS, the aforementioned Triggering Event would have
been deemed to have been cured on June 26, 1995; and

          WHEREAS, in connection with the Company's application
to have its common stock, par value $0.01 per share (the "Common
Stock") be included in the NASDAQ National Market System
("NASDAQ/NMS"), NASDAQ/NMS has required that the Board revert to
its original structure of seven members; and

          WHEREAS, pursuant to the Governance Agreement, the
Board was to consist of 11 directors until June 26, 1996; and

          WHEREAS, the Governance Agreement was terminated
pursuant to its terms upon the approval by the Company's
stockholders on January 26, 1996 of certain amendments to the
Company's Certificate of Incorporation; and 

          WHEREAS, the Voting Shareholders deem it to be in their
best interests and the best interests of the Company for the
Company's Common Stock to be included in NASDAQ/NMS; and

          WHEREAS, the Voting Shareholders deem it to be in their
best interests and the best interests of the Company to use all
reasonable efforts to cause the Board to revert to a seven member
board immediately.

          NOW THEREFORE, in consideration of the foregoing and
for other good and valuable consideration, the parties hereto
hereby agrees as follows:

          1.   Board of Directors

          The Board shall immediately revert to seven directors,
four of whom will be Common Directors and three of whom will be

thereto shall be governed by the Amended and Restated

          WHEREAS, the Voting Shareholders and the Company are

               1.5  The Voting Shareholders shall have, from time
to time, the right to substitute other designees in the place and
stead of their respective designees provided for herein.  The

                    and ING pursuant to Section 1.4(ii) hereof
                    shall not be an employee, associate or
                    affiliate of Huff or ING and one of whom

               1.9  In any case where Huff and ING shall have the
right jointly to designate a director, (i) such designee shall
require the approval of both Huff and ING and the refusal or
failure of either Huff or ING to approve such designee shall
prohibit such person from standing for election to the Board,
provided, that the entire Board shall then have the right to
designate a substitute designee if Huff and ING cannot agree upon
a substitute designee prior to the applicable Election of
Directors and (ii) the removal of such designee from the Board
shall require the consent of either Huff or ING.

          2.   Certain Committees
