CONCERNING THE BOARD OF DIRECTORS

Prior to October 1994, outside directors of the Company received up to $1,000
per meeting for their services to the Company in such capacity.  During the
fiscal year ended March 31, 1995, Mr. Rabb and Mr. Blume, two outside directors
of the Company, were each paid $2,000.  Mr.  Feinberg, the third outside
director, did not receive any fees.  Effective October 1994, outside directors
of the Company were granted stock options under the Company's 1994 Non-Employee
Director Stock Option Plan (the "1994 Plan") in lieu of cash compensation.
Under the 1994 Plan, the Board of Directors of the Company is authorized to
grant options to purchase up to 350,000 shares of Common Stock to certain
non-employee directors.  Under the terms of the 1994 Plan, a non-employee
director is granted options to purchase 50,000 shares of Common Stock at the
market price on the day he or she becomes a director or, in the case of outside
directors that were in office during October 1994, the date of adoption of the
1994 Plan.  The options vest at the rate of 10,000 shares per year, expire if
not exercised within ten years from the date of grant, and are
non-transferrable by option holders during an option holder's lifetime.  Under
circumstances set forth in the 1994 Plan, the options may be exercised within
six months following termination of service to the Company, or within one year
in the event of death or total disability.  In January 1995, each of Mr. Bowers
and Mr. Robert King, as consideration for his agreement to serve as a
consultant to the Company, was issued options under the Company's Amended 1993
Stock Option Plan.  Neither Mr. Bowers nor Mr. King received options under the
1994 Plan upon his appointment as a director of the Company.  Neither Mr.
Goldblatt nor Mr. Cowie, upon being appointed as a director of the Company,
accepted any options.  The option holdings of the directors are set forth under
"Item 12 - Security Ownership of Certain Beneficial Owners and Management"
below.  Directors are also reimbursed for their reasonable travel expenses
incurred in attending meetings.

The Board of Directors met or took action without a meeting eight times during
the fiscal year ended March 31, 1995.  Other than directors elected during the
year, there is no present director nominated for election who attended fewer
than 75% of the aggregate of the total number of meetings of the Board of
Directors and the total number of meetings held by all committees of the Board
of Directors on which he served.

The Board of Directors maintains an Audit Committee, an Option Committee, a
Nominating Committee and a Compensation Committee.

The Audit Committee discusses matters of concern to the independent auditor
resulting from the audit; reviews changes in accounting principles in the
financial statements; and reviews non-auditing services performed for the
Company by the independent auditor.  During the fiscal year ended March 31,
1995, the members of the Audit Committee were Mr. Feinberg and Ambassador Rabb.
The Audit Committee met once during fiscal 1995, and both members of the
Committee were present at the meeting.

The Option Committee administers the 1993 Stock Option Plan.  During the fiscal
year ended March 31, 1995, the members of the Option Committee were Mr.
Caravetta, Ambassador Rabb and Mr. Feinberg.  The Option Committee met or took
action without a meeting three times during fiscal 1995, and all members of the
Option Committee were present at all meetings.

indemnify the director against certain claims that may be asserted against him
by reason of serving on the Board of Directors.

of the legal fees for the 1996 fiscal year can be made at this time.  Mr.
Goldblatt is also a member of the Advisory Committee of Frontenac Company, a
Delaware general partnership that is the general partner of Frontenac VI
Limited Partnership ("Frontenac VI").  The Company is contemplating an issuance
of 1,500,000 shares of Series A Convertible Preferred Stock, warrants to

Directors.  During the first year of the agreement, fifty percent (50%) of the
total bonus is guaranteed.  The agreement provides for one year severance
unless there is termination for cause or a voluntary resignation without good
reason as defined in his Employment Agreement.  Mr. King was issued 300,000
shares of Common Stock of the Company in lieu of a cash signing bonus.  In the
event that prior to the first or second anniversary of his employment Mr. King
voluntarily resigns without good reason, or is terminated for cause, prior to a
change of control as defined in his Employment Agreement, he will return
200,000 or 100,000 shares, respectively, for cancellation.  Mr. King has agreed
with the Company not to sell more than 33,333 of these shares plus any
shortfall from previous fiscal quarters in any fiscal quarter during Mr. King's
employment.

Mr. King was granted stock options to acquire 1,000,000 shares of Common Stock
of the Company at the market price ($3.50/share) on the date of the
commencement of his employment. These stock options vest whenever the stock has
traded at or above $5.00 on at least 30 of the 40 prior business days, or upon
a change of control.  Alternatively, 400,000 shares vest on October 12, 1995
and 600,000 shares vest on October 12, 2002, unless they have previously become
exercisable.  These options contain anti-dilution provisions authorizing
adjustments under certain circumstances.  Mr. King's shares, including those
underlying options, are subject to a registration rights agreement.  The
Company has also agreed to reimburse Mr. King for the cost of a term life
insurance policy for $1,000,000 on Mr. King's life for his benefit.

On June 14, 1995, the Company agreed to loan Mr. Graham King $157,800 in order
to allow Mr. King to pay the income taxes due in connection with a portion of
the restricted stock he received.  The terms of the note evidencing the loan
provide that the loan is interest-free until 120 days after the Company
registers Mr. King's restricted stock for sale, that the loan bears interest at
a rate equal to the rate of return achieved by the Company on its cash reserves
plus 1% after such date, and that the Company may demand repayment at any time
after the note begins to accrue interest.

On October 12, 1994, the Company entered into a Senior Consulting Agreement
with Mr. Caravetta.  This agreement was amended by a letter dated November 11,
1994.  The Senior Consulting Agreement replaced and superceded a prior
employment agreement between Mr. Caravetta and the Company.  The agreement
provides for a salary of $275,000 per annum, and provides a split dollar life
insurance policy on the lives of Mr. and Mrs.  Caravetta in the face amount of
$2,000,000 through the end of the





                                       7
<PAGE>   9

term of the agreement, which is April 1, 1998.  Pursuant to the Senior
Consulting Agreement, a stock option for 150,000 common shares granted to Mr.
Caravetta by the Company was canceled.

Mr. Caravetta's Senior Consulting Agreement includes a change of control clause
that provides that, in the event of a change of control of the Company during
the term of Mr. Caravetta's agreement, the Company shall pay him an amount
equal to 2.9 times the average annual base compensation paid to him during the
five fiscal years of the Company immediately preceding the change of control,
provided such change of control takes place on or before March 31, 1996.  If
such change of control takes place between April 1, 1996 and March 31, 1997,
the Company shall pay him an amount equal to two times such average annual
compensation; and, if such change of control takes place between April 1, 1997
and March 31, 1998, the Company shall pay him an amount equal to 1.5 times the
average annual base salary and incentive compensation.  The aforesaid payment
shall be made to him in twelve or, at his election, in twenty-four, equal
monthly installments, commencing on the first day of the month following the
change of control.  Other than the change of control payments, Mr. Caravetta
shall not be entitled to any other salary or consulting payments under the
Senior Consulting Agreement after a change of control.  Mr. Caravetta has
agreed that a change of control in favor of Mr. King or persons affiliated with
Mr. King shall not be deemed a change in control for purposes of his Senior
Consulting Agreement.

Mr. Caravetta's agreement also contains clauses that provide for medical
insurance coverage for the remainder of his and his wife's life (at her expense
following his death).  The Company also maintains a term life policy in the
face amount of $500,000 on the life of Mr. Caravetta, payable to Mr.
Caravetta's wife or her estate.

The Company has in effect an employment contract with Mr. Pesce that provides
for salary of $180,000 per annum, plus an incentive bonus of 2- 1/2% of pretax
profits above $500,000.  This agreement also contains a one year salary
continuation clause which provides that Mr. Pesce will receive one year's
salary if he is terminated for any reason other than cause.

Mr. Schleck has been employed by the Company for nineteen years.

(1)Other than column (f), amounts reported in these columns represent amounts
that may be realized upon exercise of the options immediately prior to the
expiration of their term assuming the specified compounded rates of
appreciation (5% and 10%) of the Company's Common Stock over the term of the
options.  These numbers are calculated based on rules promulgated by the
Securities and Exchange Commission and do not reflect the Company's estimate of
future stock price increases.  Actual gains, if any, on stock option exercises
and Common Stock holdings are dependent on the timing of such exercise and the
future performance of the Company's Common Stock.  There can be no assurance
that the rates of appreciation assumed in this table can be achieved or that
the amounts reflected will be received by the individuals.

ITEM 13:       CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

On July 18, 1995, the Company entered into a Series A Convertible Preferred
Stock and Warrant Purchase Agreement (the "Purchase Agreement"), by and among
the Company, Frontenac VI, a trust established for the benefit of Robert E.
King and his descendants and Morgan Holland Fund II, L.P.  (collectively the
"Purchasers"), pursuant to which the Company has agreed (subject to approval of
the Company's stockholders and certain other conditions) to sell to the
Purchasers, through a private placement, (i) 1,500,000 shares of Series A
Convertible Preferred Stock of the Company, par value $0.01 per share, (ii)
warrants to purchase up to 390,000 shares of the Company's Common Stock at an
exercise price of $0.10 per share, and (iii) warrants to purchase up to 198,000
shares of the Company's Common Stock at an exercise price of $3.50 per share,
for an aggregate purchase price of $6,000,000.

A copy of the Purchase Agreement, together with certain of the exhibits
thereto, is attached hereto as Exhibit 10(37), and is hereby incorporated by
reference.  The above description is qualified in its entirety by reference to
such exhibit.

Additional information with respect to Certain Relationships and Related
Transactions is included herein under the headings "Concerning the Board of
Directors" and "Executive Compensation."



                               SECTION 16 FILINGS

Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
directors, executive officers and persons who own beneficially more than ten
percent of a registered class of the Company's equity securities to file with
the Securities and Exchange Commission ("SEC") initial reports of ownership and
reports of changes in ownership of such securities of the Company.  Directors,
executive officers and greater than ten percent stockholders are required by
SEC regulations to furnish the Company with copies of all Section 16(a) reports
they file.

To the Company's knowledge, based solely on a review of the copies of such
reports furnished to the Company and representations that no other reports were
required, all Section 16(a) filing requirements applicable to its directors,
executive officers and greater than ten percent beneficial owners were complied
with during the 1994 fiscal year, except that Mr. Loscalzo did not make a Form
3 filing within the time period established by Section 16(a).

"Material Adverse Effect").

       3.2    Authorization.  All corporate action on the part of the Company

respective terms.  Prior to the Closing, the Restated Certificate and the
Certificate of Designation will have been filed with the Secretary of State of

rights of first refusal, encumbrances, claims, preemptive rights and other
third party rights ("Liens"), other than restrictions on transfer under this
Agreement, the Warrants, the Registration Rights Agreement and applicable state
and federal securities law.

       The Common Stock issuable upon conversion of the Series A Preferred
Stock, and exercise of the Series A Warrants and the Series B Warrants will be
duly and validly reserved for issuance and, when issued in compliance with the
provisions of the Restated Certificate, the Certificate of Designation and the

Company in connection with the Company's valid execution, delivery or
performance of this Agreement, the Registration Rights Agreement (other than
Consents required in connection with the Company's performance of its
obligations under the Registration Rights Agreement), and the sale, issuance or
delivery of the Series A Preferred Stock, the Series A Warrants and the Series
B Warrants by the Company pursuant to the terms hereof or the Common Stock

in a Material Adverse Effect.

of the Company will consist immediately prior to the Closing of:

          (i) Preferred Stock.  10,000,000 shares of Preferred Stock, of which

shares of Common Stock pursuant to the Company Option Plans (as defined below),
there are not outstanding any options, warrants, rights (including conversion
or preemptive rights and rights of first refusal), or agreements for the
purchase or acquisition from the Company of any shares of its capital stock.
In addition to the aforementioned options, the Company has reserved an
additional 772,833 shares of its Common Stock for purchase upon exercise of
options to be granted in the future under the Company Option Plans and, to the
Company's knowledge, there is no agreement or understanding between any persons
that affects or relates to the voting or giving of written consents with

Stock Option Plan, as amended, (ii) the 1994 Non-Employee Director Stock Option

person in which the Company, directly or indirectly, owns a majority of the
securities having ordinary voting power for the election of directors (the
"Subsidiaries").  Each of the Subsidiaries is duly organized and existing under
the laws of the jurisdiction in which it is incorporated or organized and is in
good standing under such laws.  Each Subsidiary is duly qualified to transact
business and is in good standing in every jurisdiction (domestic or foreign) in
which the nature of the respective business conducted or property owned by it
makes such a qualification necessary and where the failure to so qualify would
result in a Material Adverse Effect.  All of the outstanding shares of the
capital stock of each of the Subsidiaries have been duly and validly authorized
and issued, are fully paid and nonassessable, and are owned by the Company,
free and clear of any Liens other than Liens securing existing bank debt
(disclosed on the Disclosure Schedule).  There are not outstanding any options,
warrants, rights (including conversion or preemptive rights and rights of first
refusal) or agreements for the purchase or acquisition from any Subsidiary of
any shares of its capital stock.  None of the Subsidiaries is a party or
subject to any agreement or understanding, and, to the best of the Company's
knowledge, there is no agreement or understanding between any persons, that
affect or relates to the voting or giving of written consents with respect to
any security or the voting by a director of any of the Subsidiaries.

indentures and instruments which are in effect as of the date of this Agreement
and are required to be disclosed under Regulation S-K or in the Company's

Neither the Company nor any of the Subsidiaries is in default under any

Neither the Company nor any of the Subsidiaries is in default of or in
violation in any material respect of any of such franchises, permits, licenses
or other similar authority, except for defaults or violations which would not
result in a Material Adverse Effect.

the Subsidiaries.  Neither the execution, delivery or performance of this
Agreement and the Registration Rights Agreement, nor the execution and filing
of the Restated Certificate or the Certificate of Designation, nor the issuance
of the Securities hereunder, nor fulfillment of nor compliance with the terms
and provisions hereof or thereof, nor the payment of dividends on the Series A
Preferred Stock as contemplated by the Certificate of Designation out of funds
legally available therefor, nor the redemption thereof out of funds legally
available therefor will conflict with or result in a breach of the terms,
conditions or provisions of, or give rise to a right of termination under, or
constitute a default under, or result in any violation of, the Charter or
Bylaws of the Company or any of the Subsidiaries, or any mortgage, agreement,
instrument, order, judgment, decree, statute, rule or regulation to which the
Company or any of the Subsidiaries or any of their respective property is
subject, other than conflicts, breaches, defaults, terminations or violations
which, individually or in the aggregate, do not result in a Material Adverse
Effect or materially adversely affect the ability of the Company to perform its
obligations under this Agreement, the Registration Rights Agreement,  the
Restated Certificate or the Certificate of Designation.

       3.11   Litigation.  There is no action, suit, proceeding, or
investigation pending or, to the Company's knowledge, currently threatened
against the Company, or any of the Subsidiaries or any of their respective
properties or assets, that questions the validity of this Agreement or the
Registration Rights Agreement or the right of the Company to enter into such
agreements, or to consummate the transactions contemplated hereby or thereby,
or that is reasonably expected to result, either individually or in the
aggregate, in a Material Adverse Effect, or in any material change in the
current equity ownership of the Company or the

       3.16   Disclosure.  Neither this Agreement nor the Disclosure Schedule
or exhibits hereto contains any untrue statement of a material fact or omits to
state a material fact necessary in order to make the statements contained
herein and therein not misleading, when taken as a whole.  There is no fact
peculiar to the Company or any of the Subsidiaries of which the Company is
aware which the Company has not disclosed to the Investors in writing which
would result, or has resulted in, a Material Adverse Effect or, so far as the
Company can now reasonably foresee, will materially adversely affect the
ability of the Company to perform this Agreement, the Registration Rights
Agreement or its obligations in respect of the Securities.

       3.17   ERISA.

       (a)    The Disclosure Schedule sets forth a true, correct, and complete
list of all Company Plans.  The Company and the Subsidiaries have, with respect
to each Company Plan, delivered to the Investor true and complete copies of (i)
all Plan documents and agreements; (i) the most recent summary Plan description
for each Plan and material employee communications; (iii) the most recent
annual report (including all Schedules thereto, if any); and (iv) if the Plan
is intended to qualify under Section 401(a) or 403(a) of the Code, the most
recent determination letter received from the Internal Revenue Service or
opinion letter received from the sponsor of a prototype plan.

       (b)    With respect to each Plan, neither the Company nor any of the
Subsidiaries has direct or indirect, actual or contingent, liability which
would result in a Material Adverse Effect, other than to make payments for
contributions, premiums or benefits or other expenses related to such Plans
when due in the ordinary course, all of which payments that are due have been
made and no Plan is a "defined benefit plan" (as defined in Section 3(35) of
ERISA).  No assets of the Company or any of the Subsidiaries are subject to any
lien under Sections 302(f), 306(a), 307(a), 412 or 4068 of ERISA or Sections
401(a)(29) or 312(n) of the Code.

       (c)    With respect to each Company Plan:  (i) each such Plan conforms
to, and its administration is in compliance with, all applicable laws and
regulations, except where the failure to conform or comply would not result in
a Material Adverse Effect; (ii) the form of each such Plan intended to qualify
under Sections 401(a) or 403(a) of the Code so qualifies except for the

Subsidiaries beyond the thirtieth day following their retirement or other
termination of service (other than coverage mandated under Section 4980B of the
Code).

       3.18   Environmental Matters.  Neither the Company nor any of the
Subsidiaries has disposed of or arranged for the disposal of any hazardous
substances, other than in conformity with applicable laws and regulations, at
any facility, location or site owned or leased by the Company or any of the

thereunder.

any similar securities of the Company for sale or exchange to, solicited any
offers to buy such securities of the Company from or otherwise approached or
negotiated with respect to such securities of the Company with, any person
other than the Investors and a limited number of other Persons that it believed
were "accredited investors" (as defined in Rule 501(a) under the Securities
Act).  Based in part on the accuracy of the representations and warranties of
the Investors contained herein, neither the Company nor any person acting on
its behalf has taken or will take any action (including, without limitation,
any offering of any securities of the Company under circumstances which would
require the integration of such offering with the offering of the Securities
under the Securities Act and the rules and regulations of the Commission
thereunder) which might subject the offering, issuance or exchange of the
Securities to the registration

       (a)    The Disclosure Schedule contains a listing of all software and
databases that are material to the conduct of the business of the Company and
the Subsidiaries, taken as a whole, in which the Company or any of the
Subsidiaries:  (i) holds any ownership interest ("Owned Software"); or (ii)
holds written license to use (with said license agreement being also
identified), but excluding PC based software that is available pursuant to
"shrink wrap" agreements ("Third Party Software", Owned Software and Third
Party Software being referred to collectively as "Software").  To the knowledge
of the Company, the Company and the Subsidiaries do not use any software or
databases that are material to the business of the Company and the
Subsidiaries, taken as a whole, for which the user has neither ownership rights
nor a valid license.

       (b)    To the knowledge of the Company, the Company or one of the
Subsidiaries possesses legal rights in the Software that are sufficient to
conduct the business of the Company and the Subsidiaries as the same is
presently conducted.

       (c)    To the knowledge of the Company, there are no outstanding
options, licenses or agreements of any kind relating to the Software to which

Adverse Effect.

pending for recognition of such employees, no election for certification is
pending, and, to the Company's knowledge, no such demand is scheduled.

and the consummation of the transactions contemplated by this Agreement by the
Investor have been duly approved by all necessary proceedings on the part of
the Investor.  This Agreement has been duly executed and delivered by the
Investor.  This Agreement constitutes a valid and legally binding obligation of
such Investor, enforceable in accordance with its terms.

       4.2    Governmental Consents.  No Consent is required on the part of the
Investor in connection with the execution and delivery of this Agreement or the
performance by the Investor of the transactions contemplated hereby, except for
filings after the Closing under Section 13(d) of the Securities Exchange Act of
1934 (the "Exchange Act").

       4.3    Acquire Entirely for Own Account.  This Agreement is made with
the Investor in reliance upon the Investor's representation to the Company,
which by its execution of this Agreement it hereby confirms, that the
Securities to be acquired by the Investor and the Common Stock issuable upon
conversion of the Warrants will be acquired for investment for the Investor's
own account, not as a nominee or agent, and not with a view to the resale or
distribution of any part thereof, and that the Investor has no present
intention of selling, granting any participation in, or otherwise distributing
the same.  By executing this Agreement, the Investor further represents that,
it does not have any contract, undertaking, agreement or arrangement with any
person to sell, transfer or grant participation to such person or to any third
person, with respect to any of the Securities or the Common Stock issuable upon
conversion of the Securities.

       4.4    Reliance Upon Investor's Representations.  The Investor
understands that the Securities are not, and any Common Stock acquired upon
conversion thereof at the time of issuance may not be, registered under the
Securities Act on the ground that the acquisition provided for in this
Agreement and the issuance of securities hereunder is exempt from registration
under the Securities Act pursuant to Section 4(2) thereof, and that the
Company's reliance on such exemption is predicated on the Investor's
representations set forth herein.

       4.5    Sophisticated Investor.  The Investor is an "accredited investor"
as defined in Rule 501(a) under the Securities Act.  The Investor is a
sophisticated purchaser with respect to the Securities, has been given the
opportunity to access the records of the Company and its Subsidiaries and has
made its own independent analysis and investigation into the business,
operations, financial condition and general creditworthiness of the Company and
the Subsidiaries and has made its own independent decision to acquire the
Securities pursuant to the terms and conditions set forth in this Agreement,
except that the Investor has relied upon the representations, warranties and
covenants of the Company contained in this Agreement.

       4.6    Restricted Securities.  The Investor understands that the
Securities may not be sold, transferred, or otherwise disposed of without
registration under the Securities Act or an exemption therefrom, and that in
the absence of an effective registration statement covering the Securities or
an available exemption from registration under the Securities Act, the
Securities

must be held indefinitely to redemption in accordance with their terms.  In
particular, the Investor is aware that the Securities may not be sold pursuant
to Rule 144 promulgated under the Securities Act unless all of the conditions
of that Rule are met.

Securities being acquired hereunder shall be endorsed with the legend set forth
below, and the Investor covenants that, except to the extent such restrictions
are waived by the Company, the Investor shall not transfer the shares
represented by any such certificate without complying with the restrictions on
transfer described in the legend endorsed on such certificate,

       with respect to the Series A Preferred Stock:

       "THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE

       NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, OR HYPOTHECATED IN THE
       ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO SUCH
       SHARES UNDER SUCH ACT OR LAWS OR UNLESS THE COMPANY HAS RECEIVED AN
       OPINION OF COUNSEL, SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT
       SUCH REGISTRATION IS NOT REQUIRED."

       NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY
       STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED,
       PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN
       EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR SUCH LAWS OR
       UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL, SATISFACTORY TO
       THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED."

    5. COVENANTS OF THE COMPANY

       5.1    Financial Statements and Other Reports.  The Company agrees that

       (ii)   promptly upon production thereof and in any event, no later than

(adopted by the Board of Directors of the Company) for such fiscal year
prepared for each month, including projected cash flow and capital expenditure
budgets for each month supported by a narrative describing the assumptions upon

       (iii)  such other financial information as shall be reasonably requested
by a holder of the Securities promptly after such holder provides a written
request with respect thereto to the Company.

       5.2    Inspection of Property.  As long as any Investor or any of such
Investor's Affiliates shall hold at least 100,000 shares of the Series A

Company and its Subsidiaries, to examine the corporate books and make copies or
extracts therefrom and to discuss the affairs, finances and accounts of the
Company and its Subsidiaries with the principal officers of the Company, all at
such reasonable times and as often as such Investor may reasonably request.

obtained by it pursuant to Section 5.1 or this Section 5.2 until such
information or data otherwise becomes publicly available or except pursuant to
a valid subpoena, judicial process or its equivalent or as otherwise required
by applicable law;  provided, however, such Investor shall have used its best
efforts to give the company advance notice of such subpoena or judicial process
so that the Company may seek an appropriate protective order.  Such Investor
will take appropriate measures to limit the communication of material
non-public information concerning the Company and the Subsidiaries to those of
its agents, employees, partners and representatives who have a genuine and bona
fide need to know the same.  Such Investor will advise its agents, employees,
partners and representatives who do receive such information of the obligation
of such Investor hereunder and of the obligations imposed under the federal and
state securities laws.  "Affiliate" shall have the meaning set forth under Rule
12b-2 of the Exchange Act.

receipt of evidence satisfactory to the Company of the loss, theft, destruction
or mutilation of any certificate representing the Securities, in the case of

satisfactory to the Company, or, in the case of mutilation, upon surrender and
cancellation thereof, the Company will issue a new certificate of like tenor

or the Series B

of the Series A Preferred Stock remain outstanding, the Company shall not (a)
alter or change the rights, preferences or privileges of the Series A Preferred

distribution of assets upon liquidation, without the written consent of holders
of not less than a majority of the shares of Series A Preferred Stock then
outstanding.

       5.5    Reporting Requirements.  As long as the Company is subject to the
periodic reporting requirements of the Exchange Act, the Company will file all

limitation, any officer or director of any Affiliate) involving, directly or
indirectly, the payment of money or transfer of property to such Affiliate or
officer or director of such Affiliate, having an aggregate value in excess of
$250,000, except for (i) such transactions, arrangements or agreements which
the Preferred Director (as defined in the Certificate of Designation) has
consented to in writing or (ii) customary employment arrangements and benefit
programs on reasonable terms no less favorable to the Company or any Subsidiary
than would be obtained by the Company or any Subsidiary in a comparable
arm's-length transaction with a Person who is not an Affiliate of the Company
or any Subsidiary.

       5.7    Acquisition of Assets; Investments.  As long as not less than
300,000 shares of the Series A Preferred Stock remain outstanding, the Company

capital stock of any Person) for consideration in excess of $1,000,000, unless
such purchase or acquisition has been approved by a majority of the Board of
Directors of the Company.

       5.8    Additional Rights and Limitations of Series A Preferred Stock.

of Common Stock pursuant to an underwritten registered offering or issuances or
deemed issuances of Common Stock in connection with the acquisition of the
assets or securities of any Person.

       (b)  If an issuance of Common Stock gives rise to a preemptive right
under this Section 5.8, the Company shall give all holders of Series A
Preferred Stock written notice of such issuance within thirty (30) days prior
to such issuance, which notice shall set forth the price and terms of such
issuance.  A holder of Series A Preferred Stock may exercise the preemptive
right granted in this Section 5.8 only by giving written notice of exercise to
the Company within fifteen (15) days following the receipt of the Company's
notice to the holder.  The holder's notice of exercise shall specify the number

Common Stock for purpose of this Section 5.8, it shall be assumed that all
outstanding options or rights to purchase Common Stock have been exercised and

so exchanged or converted.  The rights contained in this Section 5.8 may be
waived or amended in accordance with the provisions of Section 9.9 hereof.

Party, would entitle the Investor Indemnified Party to indemnity pursuant to
this Section 8.1, the Investor Indemnified Party shall promptly but in no event
later than

fifteen (15) days from the date that such action, proceeding or claim was
commenced, notify the Company of the same in writing specifying in detail the
basis of such claim and the facts pertaining thereto, and the Company shall be
entitled to assume the defense thereof and have the sole control of the defense
and settlement thereof, including the employment of counsel and the payment of
all expenses; provided, however, that the Investor Indemnified Party shall have
the right to employ counsel separate from counsel employed by the Company in
any such action and to participate in the defense thereof, and the fees and
expenses of such counsel shall be at the expense of the Investor Indemnified
Party unless (i) (1) the employment thereof has been specifically authorized by
the Company in writing or (2) the use of counsel chosen by the Company to
represent the Investor Indemnified Party would present such counsel with a
conflict of interest or (ii) the Company has failed to assume the defense and
to employ counsel.  The Company shall not be liable for any settlement of any
such action or proceeding effected without the written consent of the Company
(unless such consent is unreasonably withheld by the Company), but if settled
with the written consent of the Company, or if there shall be a final judgment
for plaintiff in any such action, the Company agrees to indemnify and hold
harmless the Investor Indemnified Party from and against any and all Losses by
reason of such settlement or judgment.  Notwithstanding the foregoing, without
the written consent of the Investor Indemnified Party, the Company shall not be
entitled to settle any nonmonetary claim involving the business, operations or
assets of the Investor Indemnified Party if such settlement would impose on it
any obligation which cannot be satisfied by the payment of money.

       8.2    Contribution.  If the indemnification provided in this Section 8
were to be unavailable to the parties hereto for any reason, the Company and
the Investors will contribute to the Losses in the proportion that the
Company's interest bears to each Investor's interest (on a pro rata basis) in
the matters contemplated by this Agreement.

                 restrictions, including without limitation restrictions on
                 transferability, and qualifications of shares of such series,
                 not inconsistent with law and this Restated Certificate of
                 Incorporation.

                 2.2      Any shares of any series of Preferred Stock which
         shall at any time be acquired by the Corporation by reasons of
         redemption or otherwise shall become part of the authorized but
         undesignated Preferred Stock and be subject to designation as provided
         in Section 2.1.

                 2.3      The amendment of the terms of any certificate of
         designation of any series of the Preferred Stock of which shares are
         outstanding shall require only (i) that the Board of Directors of the
         Corporation adopt a resolution setting forth the amendment proposed,
         declaring its advisability, and either calling a special meeting of
         the holders of such series of Preferred Stock for consideration of
         such amendment or directing that the amendment proposed be considered
         at the next annual meeting of stockholders by the holders of such
         series of Preferred Stock (in either event, subject to the ability of
         such holders to act by written consent in lieu of a meeting), and (ii)
         that the holders of a majority (or such greater number as may be
         required by the certificate of designation of such series)

         of the outstanding shares of such series of Preferred Stock have voted
         in favor of the amendment.  Except for holders of a series of
         Preferred Stock the terms of which are being amended, no holder of
         Common Stock and no holder of any series of Preferred Stock shall be
         entitled to vote upon such amendment unless the rights of such holders
         would be adversely affected by such amendment or such vote shall
         otherwise be required by law or by any certificate of designation of
         any series of Preferred Stock.

conferred by law:

                 (1)      Subject to any limitations set forth in the
         Certificate of Designation with respect to any series of Preferred

         from time to time shall be fixed by, or in the manner provided in, the
         by-laws of the Corporation.  Election of directors need not be by
         written ballot unless the by-laws of the Corporation so provide.

                 (2)      The Board of Directors of the Corporation shall have
         the power without the assent or vote of the stockholders:

                 (a)      To make, alter, amend, change, add to or repeal the

                 extent, and at what times and places, and under what
                 conditions and regulations, the accounts and books of the
                 Corporation (other than the stock ledger) or any of them,
                 shall be open to the inspection of the stockholders.

                                                              Purchase Agreement


                 (3)      The Board of Directors of the Corporation may, in its
         discretion, submit any contract or act for approval or ratification at
         any annual meeting of the stockholders or in any meeting of the
         stockholders called for the purpose of considering any such act or
         contract, and any contract or act that shall be approved or be
         ratified by the vote of the holders of a majority of the stock of the
         Corporation which is represented in person or by proxy at such meeting
         and entitled to vote thereat (provided that a lawful quorum of
         stockholders be there represented in person or by proxy) shall be as
         valid and as binding upon the Corporation and upon all the
         stockholders as though it had been approved or ratified by every
         stockholder of the Corporation, whether or not the contract or act
         would otherwise be open to legal attack because of directors'
         interest, or for any other reason.

                 (4)      In addition to the powers and authorities set forth
         herein or by statute expressly conferred upon it, the Board of
         Directors of the Corporation is hereby empowered to exercise all such
         powers and do all such acts and things as may be exercised or done by
         the Corporation; subject to the provisions of the General Corporation
         Law of the State of Delaware, as amended from time to time, this
         Amended and Restated Certificate, and the by-laws of the Corporation
         from time to time adopted by the stockholders; provided, however, that
         no by-law of the Corporation so adopted shall invalidate any prior act
         of the directors which would have been valid if such by-law of the
         Corporation had not been adopted.

To the extent any committee of directors of the Corporation is lawfully
entitled to exercise the powers of the Board of Directors of the Corporation,
such committee may exercise any right or authority of the Board of Directors
under this Amended and Restated Certificate of Incorporation and references
herein to the Board of Directors of the Corporation shall include any committee
thereof.

         SIXTH:  No holder of any of the shares of the stock of the

as of right to purchase or subscribe for (1) any unissued stock of any class,
or (2) any additional shares of any class to be issued by reason of any
increase of the authorized capital stock of the Corporation of any class, or
(3) bonds, certificates of indebtedness, debentures or other securities
convertible into stock of the Corporation, or carrying any right to purchase
stock of any class, but any such unissued stock or such additional authorized
issue of any stock or of other securities convertible into stock, or carrying
any right to purchase stock, may be issued and disposed of pursuant to
resolution of the Board of Directors of the Corporation to such persons, firms,
corporations or associations and upon such

                                                              Purchase Agreement


terms as may be deemed advisable by the Board of Directors of the Corporation
in the exercise of its discretion.

         SEVENTH:         Whenever a compromise or arrangement is proposed
between the Corporation and its creditors or any class of them and/or between
the Corporation and its stockholders or any class of them, any court of
equitable jurisdiction within the State of Delaware may, on the application in
a summary way of the Corporation or of any creditor or stockholder thereof or
on the application of any receiver or receivers appointed for the Corporation
under the provisions of Section 291 of the Law, as amended from time to time,
or on the application of trustees in dissolution or of any receiver or
receivers appointed for the Corporation under the provisions of Section 279 of
the Law, as amended from time to time, order a meeting of the creditors or
class of creditors, and/or of the stockholders or class of stockholders of the
Corporation, as the case may be, to be summoned in such manner as the said
court directs.  If a majority in number representing three-fourths in value of
the creditors or class of creditors, and/or of the stockholders or class of
stockholders of the Corporation, as the case may be, agree to any compromise or
arrangement and to any reorganization of the Corporation as a consequence of
such compromise or arrangement, said comprise or arrangement and said
reorganization shall, if sanctioned by the court to which said application has
been made, be binding on all the creditors or class of creditors, and/or on all
the stockholders or class of stockholders, of the Corporation, as the case may
be, and also on the Corporation.

         EIGHTH: The Corporation shall, to the full extent permitted by Section
145 of the Delaware General Corporation Law of the State of Delaware, as
amended from time to time, indemnify all persons whom it may indemnify pursuant
thereto.

         NINTH:  The Corporation reserves the right to amend, alter, change or
repeal any provisions contained in the certificate of incorporation in the
manner now or hereafter prescribed by statute and all rights conferred on
officers, directors and stockholders herein are granted subject to this
reservation.

         TENTH:  No director of the Corporation shall be liable to the
Corporation or any of its stockholders for monetary damages for breaches of
fiduciary duty as a director to the extent permitted by law, except that this
provision shall not eliminate or limit the liability of any director (1) for
any breach of the director's duty of loyalty to the Corporation or its
stockholders, (2) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (3) under Section 174 of
the Law, as amended from time to time, or (4) for any transaction from which
the director derived an improper personal benefit.

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

                         PURSUANT TO SECTION 151 OF THE
                GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

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



        MICRO Healthsystems, Inc., a Delaware corporation (the "Corporation),
hereby certifies that pursuant to the authority contained in Article Fourth of
the Corporation's Amended and Restated Certificate of Incorporation (the
"Restated Certificate of Incorporation"), and in accordance with the provisions
of Section 151 of the General Corporation Law of the State of Delaware, the
following resolution was duly adopted by the Board of Directors of the
Corporation, creating a series of its Preferred Stock designated as "Series A
Convertible Preferred Stock":

        RESOLVED, that there is hereby created a series of the Preferred Stock
of the Corporation designated Series A Convertible Preferred Stock, par value
$.01 per share (the "Series A Preferred Stock"), consisting of 1,500,000 shares
and having the voting powers, preferences and relative, participating,
optional, conversion and other special rights, and the qualifications,
limitations or restrictions, hereinafter set forth:

        Section 1.  Dividends.

                1A.   General Obligation.  When and as declared by the 
Corporation's Board of Directors and to the extent permitted under the General
Corporation Law of Delaware, the Corporation will pay preferential
cumulative dividends to the holders of Series A Preferred Stock as provided in
this Section 1.  Except as otherwise provided herein, dividends on each share
of Series A Preferred Stock will accrue on a daily basis at the rate of 8%
compounded quarterly on each Dividend Reference Date (defined below) per annum
of the Liquidation Value thereof plus accumulated and unpaid dividends thereon
from and including the date of issuance of such share of Series A Preferred
Stock to and including the earlier of (i) the date on which the

                                                                  Exhibit A-2 To
                                                              Purchase Agreement


Liquidation Value of such share of Series A Preferred Stock plus any accrued
and unpaid dividends thereon is paid upon any liquidation, dissolution or
winding up of the Corporation, (ii) the date on which such share of Series A
Preferred Stock is converted into Common Stock or (iii) the date on which such
share of Series A Preferred Stock is redeemed in accordance with Section 3
hereof.  Such dividends will accrue whether or not they have been declared and
whether or not there are profits, surplus or other funds of the Corporation
legally available for the payment of dividends.  The date on which the
Corporation initially issues any share of Series A Preferred Stock will be
deemed to be its "date of issuance" regardless of the number of times transfer
of such share of Series A Preferred Stock is made on the stock records
maintained by or for the Corporation and regardless of the number of
certificates which may be issued to evidence such share of Series A Preferred
Stock.

                1B.   Dividend Reference Dates.  To the extent not paid on 
March 31, June 30, September 30 and December 31 of each year (the "Dividend
Reference Dates"), all dividends which have accrued on each share of
Series A Preferred Stock outstanding during the three-month period (or other
period in the case of the initial Dividend Reference Date) shall be accumulated
and shall remain accumulated dividends with respect to each such share of
Series A Preferred Stock until paid.

                1C.   Distribution of Partial Dividend Payments.  If at any 
time the Corporation pays less than the total amount of dividends then
accrued with respect to Series A Preferred Stock, such payment will be
distributed ratably among the holders of Series A Preferred Stock on the basis
of the amount of accrued and unpaid dividends with respect to the shares of
Series A Preferred Stock owned by each such holder.

                1D.   Preference.  The holders of Series A Preferred Stock 
shall be entitled to dividends and distributions in preference and priority to
holders of Junior Securities.  The Corporation shall not, without the
prior written consent of the holders of not less than a majority of the shares
of Series A Preferred Stock then outstanding pay any dividend or distribution
(other than dividends payable solely in Junior Securities) on any Junior
Securities at any time when accumulated dividends on Series A Preferred Stock
have not been paid in full.

        Section 2.  Liquidation.

                Upon any liquidation, dissolution or winding up of the 
Corporation (a "Liquidation"), each holder of Series A Preferred Stock will be
entitled to be paid, before any distribution or payment is made upon any
Junior Securities, an amount in cash equal to the aggregate Liquidation Value
of all of such holder's shares of Series A Preferred Stock plus all

                                                              Purchase Agreement


accrued but unpaid dividends thereon.  If upon a Liquidation, the Corporation's
assets available for distribution to its stockholders after payments on Senior
Securities (as defined herein) are insufficient to permit payment to the
holders of Series A Preferred Stock of the aggregate Liquidation Value of
Series A Preferred Stock plus all accrued but unpaid dividends thereon and to
the holders of Pari Passu Securities (as defined herein) the entire
preferential amount payable with respect to any Pari Passu Securities, then the
entire assets available for distribution will be distributed, pro rata based
upon the aggregate liquidation value of the securities held by each holder
thereof, among the holders of (i) Series A Preferred Stock (pro rata based upon
the aggregate Liquidation Value of Series A Preferred Stock held by each such
holder plus all accrued but unpaid dividends thereon) and (ii) Pari Passu
Securities.  After payment in full shall have been made to the holders of
Series A Preferred Stock of the aggregate Liquidation Value of Series A
Preferred Stock plus all accrued but unpaid dividends thereon, the holders of
the Series A Preferred Stock shall not share in any remaining assets of the
Corporation available for distribution.  The Corporation will mail written
notice of a Liquidation to each record holder of Series A Preferred Stock not
less than thirty (30) days prior to the effective date thereof.  Neither the
consolidation or merger of the Corporation into or with any other corporation
or corporations, nor the sale or transfer by the Corporation of all or any part
of its assets, nor the reduction of the capital stock of the Corporation, will
be deemed to be a Liquidation within the meaning of this Section 2.

        Section 3.  Redemptions.

                3A.   Mandatory Redemption.  On August ___, 2000, the 
Corporation shall redeem all (but, subject to Section 3C, not less than all) of
Series A Preferred Stock then outstanding in accordance with this
Section 3 at a price per share of Series A Preferred Stock equal to the
Redemption Price (as defined below), which Redemption Price shall be payable in
accordance with the Amortization Schedule attached hereto as Schedule 3A.

                3B.   Redemption Price.  For each share of Series A Preferred 
Stock which is to be redeemed, the Corporation shall be obligated to pay to the
holder thereof an amount in immediately available funds (the "Redemption
Price") equal to the Liquidation Value thereof plus all accrued but unpaid
dividends thereon in accordance with the Amortization Schedule attached hereto
as Schedule 3A.  The first installment of the Redemption Price shall be paid to
each holder of Series A Preferred Stock upon surrender by such holder at the
Corporation's principal office of the certificate representing such share of
Series A Preferred Stock.  Unless the Corporation fails to pay the portion of
Redemption Price owed to the holder of a share of Series A Preferred Stock upon
presentation of the certificate representing such share on or after the date on
which such share is to be redeemed, all rights of the holder of such share
(other than

                                                              Purchase Agreement


the right to receive payment of the Redemption Price as set forth herein) shall
cease on such date, and such share shall not be deemed to be outstanding
thereafter.

                3C.   Insufficient Funds.  If the funds of the Corporation 
legally available for redemption of Series A Preferred Stock are insufficient
to redeem the total number of shares of Series A Preferred Stock to be
redeemed, those funds which are legally available will be used to redeem the
maximum possible number of shares of Series A Preferred Stock ratably among the
holders of such shares to be redeemed based upon the Redemption Price of the
Series A Preferred Stock held by each such holder.  Thereafter, when additional
funds of the Corporation are legally available for the redemption of Series A
Preferred Stock, such funds will be used to redeem the balance of the shares of
Series A Preferred Stock which the Corporation became obligated to redeem but
which it has not redeemed (such redemptions to be made on a monthly basis).  In
case fewer than the total number of shares of Series A Preferred Stock
represented by any certificate are redeemed in any installment, a new
certificate representing the number of unredeemed shares of such Series A
Preferred Stock will be issued to the holder promptly without cost to such
holder promptly after surrender of the certificate representing the redeemed
shares of Series A Preferred Stock.

                3D.   Redeemed or Otherwise Acquired Shares.  Any shares of 
Series A Preferred Stock which are redeemed or otherwise acquired by the 
Corporation will be canceled and will not be reissued, sold or otherwise 
transferred.

        Section 4.  Voting Rights.

                (a) Except as otherwise required by law, the Restated 
Certificate of Incorporation of the Corporation, as amended, or any certificate
of designation, the holders of Series A Preferred Stock will be entitled
to vote with the holders of Common Stock on each matter submitted to a vote of
the Corporation's stockholders as a single class, with each share of Series A
Preferred Stock having a number of votes equal to the number of votes possessed
by the number of shares of Common Stock into which such share of Series A
Preferred Stock is convertible as of the record date for the determination of
stockholders entitled to vote on such matter and shall be entitled to notice of
any stockholders' meeting in accordance with the  Bylaws of the Corporation.
Fractional votes shall not be permitted and any fractional voting rights
resulting from the above formula (after aggregating all shares into which
shares of Series A Preferred Stock held by each holder could be converted)
shall be rounded to the nearest whole number (with one-half being rounded
upward).

                (b)   So long as at least 300,000 shares of Series A Preferred 
Stock are then outstanding and Frontenac VI Limited Partnership owns not less
than a majority of such shares, the holders of Series A Preferred Stock,
voting as a single class, shall be entitled to elect one (1) member of the
Board of Directors who shall also be a member of the Executive Committee of the
Board of Directors (or an equivalent committee, if any) (the "Preferred
Director"). Except as otherwise required by the Restated Certificate of
Incorporation of the Corporation, as amended, or any certificate of
designation, the holders of Common Stock and the holders of Preferred Stock,
voting as a single class, shall be entitled to elect the remaining members of
the Board of Directors.

                (c)   Notwithstanding any other provision in the Restated 
Certificate of Incorporation, as amended, any certificate of designation, or
the Bylaws of the Corporation,  the Board of Directors shall not at any
time consist of more than twelve (12) members without the prior written
approval of the Preferred Director.

        Section 5.  Conversion.

                5A.   Conversion Procedure.


                        (i)  At any time and from time to time, any holder of 
shares of Series A Preferred Stock may convert all or any portion of such shares
(including any fraction of a share) into the number of shares of Common Stock
computed by dividing (a) the number of shares of Series A Preferred Stock to be
converted times $4.00 per share, by (b) the Conversion Price (as defined in
Section 5B below).


                        (ii)  Each conversion of Series A Preferred Stock will 
be deemed to have been effected as of the close of business on the date on
which the certificate or certificates representing Series A Preferred
Stock to be converted have been surrendered at the principal office of the
Corporation.  At such time as such conversion has been effected, the rights of
the holder of such Series A Preferred Stock as such holder will cease and the
Person or Persons in whose name or names any certificate or certificates for
shares of Common Stock are to be issued upon such conversion will be deemed to
have become the holder or holders of record of the shares of Common Stock
represented thereby.


                        (iii)  As soon as possible after a conversion has been 
effected and in no event later than ten (10) business days after delivery of 
the certificate representing the shares converted, the Corporation will 
deliver to the converting holder:

                                                                  Exhibit A-2 To
                                                              Purchase Agreement


                                (a)  a certificate or certificates representing
        the number of shares of Common Stock issuable by reason of such 
        conversion in such name or names and such denomination or denominations
        as the converting holder has specified;

                                (b)  the amount payable under Section 5A(vi) 
        below with respect to such conversion;

                                (c)  a certificate representing any shares of 
        Series A Preferred Stock which were represented by the certificate or 
        certificates delivered to the Corporation in connection with such 
        conversion but which were not converted; and

                                (d)  the amount of accrued but unpaid dividends
        payable under Section 1A(ii) above with respect to each share of Series
        A Preferred Stock so converted to the extent funds are legally 
        available to pay such dividends.


                        (iv)  The issuance of certificates for shares of Common
Stock upon conversion of Series A Preferred Stock will be made without charge
to the holders of such Series A Preferred Stock for any issuance tax in
respect thereof or other cost incurred by the Corporation in connection with
such conversion and the related issuance of shares of Common Stock.  Upon
conversion of any share of Series A Preferred Stock, the Corporation will take
all such actions as are necessary in order to insure that the Common Stock
issued as a result of such conversion is validly issued, fully paid and
nonassessable.


                        (v)  The Corporation will not close its books against 
the transfer of Series A Preferred Stock or of Common Stock issued or issuable
upon conversion of Series A Preferred Stock in any manner which interferes
with the timely conversion of Series A Preferred Stock.


                        (vi)  If any fractional interest in a share of Common 
Stock would, except for the provisions of this Section 5A(vi), be deliverable
upon any conversion of Series A Preferred Stock, the Corporation, in lieu of
delivering the fractional share therefor, shall pay an amount to the holder
thereof equal to the market price of such fractional interest as of the date of
conversion, as determined in good faith by the Board of Directors of the
Corporation.

                5B.   Conversion Price.

                (a)   The initial "Conversion Price" will be $4.00 per share.  
In order to prevent dilution of the conversion rights granted under this 
subdivision, the Conversion Price will be

                                                              Purchase Agreement


subject to adjustment from time to time pursuant to this Section 5B; provided,
however, that there will be no adjustment of the Conversion Price as a result
of (i) issuances or deemed issuances of Common Stock for incentive or
compensatory purposes to directors, officers and employees of, and consultants
to, the Corporation and its Subsidiaries which are from time to time approved
by the Board of Directors, including, without limitation, grants of stock
options and the issuance of Common Stock upon the exercise thereof
("Compensatory Stock"), but not exceeding any time prior to August __, 1996 (or
any time thereafter unless approved by the Board of Directors of the
Corporation), 3,057,000 shares of Common Stock (net of any repurchases of such
shares or options), subject to adjustment for all subdivisions and combinations
of Common Stock, (ii) any split, subdivision or combination of Common Stock
into a different number of securities of the same class (subject to Section
11.5 hereof) ("Split Stock"), (iii) issuances or deemed issuances of Common
Stock upon exercise or conversion, as the case may be, of the Series A Warrants
or the Series B Warrants (each as defined in the Warrant Purchase Agreement) or
the Series A Preferred Stock ("Converted Stock"), (iv) issuances or deemed
issuances of not more than 55,000 shares of Common Stock to David K. Vanco
pursuant to that certain Agreement and Plan of Merger between the Corporation,
Vanco Business Management, Inc. and David K. Vanco, as amended (subject to
adjustment for all subdivisions and combinations) ("Vanco Stock") or (v) any
distribution, granting or sale of any Purchase Rights in accordance with
Section 7 hereof ("Purchase Stock", and together with Compensatory Stock, Split
Stock, Converted Stock and Vanco Stock, the "Excluded Stock").  Anything herein
to the contrary notwithstanding, no adjustment in the Conversion Price shall be
required unless such adjustment, either by itself or with other adjustments not
previously made, would require a change of at least $.10 in such price;
provided, however, that any adjustment which by reason of this sentence is not
required to be made shall be carried forward and taken into account in any
subsequent adjustment.

                (b)   If and whenever, after the date of issuance, the 
Corporation issues or sells, or in accordance with Section 5C is deemed to have
issued or sold, any shares of its Common Stock (other than Excluded
Stock) for a consideration per share less than the Conversion Price in effect
immediately prior to the time of such issuance or sale, then forthwith upon
such issuance or sale the Conversion Price will be reduced to the conversion
price determined by dividing (a) the sum of (1) the product derived by
multiplying the Conversion Price in effect immediately prior to such issuance
or sale times the number of shares of Common Stock Deemed Outstanding
immediately prior to such issuance or sale, plus (2) the consideration, if any,
received or deemed received by the Corporation upon such issuance or sale, by
(b) the number of shares of Common Stock Deemed Outstanding immediately prior
to such issuance or sale plus the number of shares of Common Stock issued or
deemed to have been issued in such sale pursuant to this Section 5.

                                                                  Exhibit A-2 To
                                                              Purchase Agreement



                5C.   Effect on Conversion Prices of Certain Events.


                        (i)  For purposes of determining the adjusted 
Conversion Price under Section 5B(ii), the following will be applicable.

                                (a)  Issuance of Rights or Options.  If the 
        Corporation in any manner grants, issues or sells any right, warrant 
        or option to subscribe for or to purchase Common Stock or any stock or
        other securities convertible into or exchangeable for Common Stock      
        (such rights, warrants or options being herein called "Options," and
        such convertible or exchangeable stock or securities being herein
        called "Convertible Securities") (other than Excluded Stock) and the
        price per share for which Common Stock is issuable upon the exercise of
        such Options or upon conversion or exchange of any such Convertible
        Securities is less than the Conversion Price in effect immediately
        prior to the time of the granting, issuance or sale 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 amount of such Convertible Securities issuable upon the
        exercise of such Options shall be deemed to be outstanding and to have
        been issued and sold by the Corporation at the time of the granting of
        such Options for such price per share.  For purposes of this Section,
        the "price per share for which Common Stock is issuable" shall be
        determined by dividing (A) the total amount, if any, received or
        receivable by the Corporation as consideration for the granting of such
        Options, plus the minimum aggregate amount of additional consideration
        payable to the Corporation upon exercise of all such Options, plus in
        the case of such Options which relate to Convertible Securities, the
        minimum aggregate amount of additional consideration, if any, payable
        to the Corporation upon the issuance or sale of such Convertible
        Securities and the conversion or exchange thereof, 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 all such Convertible
        Securities issuable upon the exercise of such Options.  No further
        adjustment of the Conversion Price shall be made when Convertible
        Securities are actually issued upon the exercise of such Options or
        when Common Stock is actually issued upon the exercise of such Options
        or the conversion or exchange of such Convertible Securities.

                                (b)  Issuance of Convertible Securities.  If 
        the Corporation in any manner issues or sells any Convertible
        Securities (other than Excluded Stock) and the price per share for
        which Common Stock is issuable upon conversion or exchange thereof is
        less than the Conversion Price in effect immediately prior to the time
        of such issue or sale, then the maximum number of shares of Common
        Stock issuable upon conversion





                       Exhibit A-2 To Purchase Agreement

                                                                  Exhibit A-2 To
                                                              Purchase Agreement


        or exchange of such Convertible Securities shall be deemed to
        be outstanding and to have been issued and sold by the Corporation at
        the time of the issuance or sale of such Convertible Securities for
        such price per share. For the purposes of this Section, the "price per
        share for which Common Stock is issuable" shall be determined by
        dividing (A) the total amount received or receivable by the Corporation
        as consideration for the issue or sale of such Convertible Securities,
        plus the minimum aggregate amount of additional consideration, if any,
        payable to the Corporation upon the conversion or exchange thereof, by
        (B) the total maximum number of shares of Common Stock issuable upon
        the conversion or exchange of all such Convertible Securities. No
        further adjustment of the Conversion Price shall be made when Common
        Stock is actually issued upon the conversion or exchange of such
        Convertible Securities, and if any such issue or sale of such
        Convertible Securities is made upon exercise of any Options for which
        adjustments of the Conversion Price had been or are to be made pursuant
        to other provisions of this Section 5, no further adjustment of the
        Conversion Price shall be made by reason of such issue or sale.

                                (c)  Change in Option Price or Conversion Rate.
        If the purchase price provided for in any Option, the additional
        consideration (if any) payable  upon the issue, conversion or exchange
        of any Convertible Security, or the rate at which any Convertible
        Security is convertible into or exchangeable for Common Stock change at
        any time, and such change is not due solely to the operation of
        anti-dilution provisions similar in nature to those set forth in this
        Section 5, the Conversion Price in effect at the time of such change
        shall be readjusted to the Conversion Price which would have been in
        effect at such time had such Option or Convertible Security originally
        provided for such changed purchase price, additional consideration or
        changed conversion rate, as the case may be, at the time initially
        granted, issued or sold.

                                (d)  Treatment of Expired Options and 
        Unexercised Convertible Securities.  Upon the expiration of any Option
        or the termination of any right to convert or exchange any
        Convertible Security without the exercise of any such Option or right,
        the Conversion Price then in effect hereunder will be adjusted to the
        Conversion Price which would have been in effect at the time of such
        expiration or termination had such Option or Convertible Security, to
        the extent outstanding immediately prior to such expiration or
        termination, never been issued.

                                (e)  Calculation of Consideration Received.  If
        any Common Stock, Option or Convertible Security is issued or sold or
        deemed to have been issued or sold for cash, the consideration
        received therefor will be deemed to be the gross amount

                                                                  Exhibit A-2 To
                                                              Purchase Agreement


        received by the Corporation therefor.  If any Common Stock, Options or  
        Convertible Securities are issued or sold for a consideration other
        than cash, the amount of the consideration other than cash received by
        the Corporation will be the fair value of such consideration, except
        where such consideration consists of securities, in which case the
        amount of consideration received by the Corporation will be the Market
        Price thereof as of the date of receipt.  If any Common Stock, Option
        or Convertible Security is issued in connection with any merger in
        which the Corporation is the surviving corporation, the amount of
        consideration therefor will be deemed to be the fair value of such
        portion of the net assets and business of the non-surviving corporation
        as is attributable to such Common Stock, Options or Convertible
        Securities, as the case may be. The fair value of any consideration
        other than cash and securities will be determined jointly by the
        Corporation and the holders of a majority of the outstanding Series A
        Preferred Stock.  If such parties are unable to reach agreement within
        ten (10) days after the occurrence of an event requiring valuation (the
        "Valuation Event"), the fair value of such consideration will be
        determined by an independent appraiser jointly selected by the
        Corporation and the holders of a majority of the outstanding Series A
        Preferred Stock; provided if such parties are unable to reach agreement
        upon the selection of an independent appraiser within fifteen (15) days
        after the Valuation Event, within twenty-five (25) days after the
        Valuation Event, the Corporation and the holders of a majority of
        Series A Preferred Stock then outstanding will each choose a qualified
        independent appraiser reasonably acceptable to the other party and each
        such appraiser will deliver in writing its determination of the fair
        value of such consideration.  If the difference between the two
        appraisals is 10% or less of the lower amount, the fair value will be
        the average of such two appraisals.  If the difference between the two
        appraisals is greater than 10% of the lower amount, the two appraisers
        will, within thirty-five (35) days after the Valuation Event, jointly
        choose a third qualified independent appraiser.  Within forty-five (45)
        days after the Valuation Event, the third appraiser will deliver its
        determination of fair value and the final determination of the fair
        value of such consideration will be equal to the average of the two (2)
        appraisals which are nearest to each other.  The expenses of the
        appraisers will be paid one-half by the Corporation and one-half by the
        holders of Series A Preferred Stock (pro rata based on the number of
        shares of Series A Preferred Stock held).

                                (f)  Integrated Transactions.  In case any 
        Option is issued in connection with the issue or sale of other
        securities of the Corporation, together comprising one integrated
        transaction in which no specific consideration is allocated to such
        Option by the parties thereto, the Option will be deemed to have been
        issued for a consideration of $.01.

                                                                  Exhibit A-2 To
                                                              Purchase Agreement



                                (g)  Treasury Shares.  The number of shares of 
        Common Stock outstanding at any given time does not include shares
        owned or held by or for the account of the Corporation or any
        Subsidiary, and the disposition of any shares so owned or held will be
        considered an issue or sale of Common Stock.

                                (h)  Record Date.  If the Corporation takes a 
        record of the holders of Common Stock for the purpose of entitling them
        (i) to receive a dividend or other distribution payable in Common
        Stock, Options or Convertible Securities or (ii) to subscribe for or
        purchase Common Stock, Options or Convertible Securities, then such
        record date will be deemed to be the date of the issue or sale of the
        shares of Common Stock deemed to have been issued or sold upon the
        declaration of such dividend or upon the making of such other
        distribution or the date of the granting of such right of subscription
        or purchase, as the case may be.

                5D.  Subdivision or Combination of Common Stock.  If the 
Corporation at any time subdivides (by any stock split, stock dividend,
recapitalization or otherwise) its outstanding shares of Common Stock into
a greater number of shares, the Conversion Price in effect immediately prior to
such subdivision will be proportionately reduced, and if the Corporation at any
time combines (by combination, reverse stock split or otherwise) its
outstanding shares of Common Stock into a smaller number of shares, the
Conversion Price in effect immediately prior to such combination will be
proportionately increased.

                5E.   Reorganization, Reclassification, Consolidation, Merger 
or Sale.  Any capital reorganization, reclassification, consolidation, merger,
exchange of shares or sale or transfer or more than 80% of the
Corporation's assets to another Person which is effected in such a way that
holders of Common Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities or assets with respect to or in
exchange for Common Stock is referred to herein as a "Corporate Change."  Prior
to the consummation of any Corporate Change, the Corporation will make
appropriate provisions (in form and substance reasonably satisfactory to the
holders of a majority of Series A Preferred Stock then outstanding) to insure
that each of the holders of Series A Preferred Stock will thereafter have the
right to acquire and receive, in lieu of or (if additional consideration is
received) in addition to the shares of Common Stock immediate theretofore
acquirable and receivable upon the conversion of such holder's Series A
Preferred Stock, such shares of stock, securities or assets as such holder
would have received in connection with such Corporate Change if such holder had
converted its Series A Preferred Stock immediately prior to such Corporate
Change.  In any such case, the Corporation will make appropriate provisions (in
form and substance reasonably satisfactory to the holders of a majority of
Series A Preferred Stock then outstanding) to insure that the

                                                              Purchase Agreement


provisions of this Section 5 and Sections 6 and 7 will thereafter be applicable
to Series A Preferred Stock (including, without limitation, in the case of any
such consolidation, merger or sale in which the successor corporation or
purchasing corporation is other than the Corporation, an immediate adjustment
of the Conversion Price to the value for the Common Stock reflected by the
terms of such consolidation, merger or sale).  The Corporation will not effect
any such consolidation, merger or sale, unless prior to the consummation
thereof, the successor corporation (if other than the Corporation) resulting
from such consolidation or merger or the corporation purchasing such assets
assumes by written instrument (in form and substance reasonably satisfactory to
the holders of a majority of Series A Preferred Stock then outstanding), the
obligation to deliver to each such holder such shares of stock, securities or
assets as, in accordance with the foregoing provisions, such holder may be
entitled to acquire.

                5F.   Certain Events.  If any event occurs of the type 
contemplated by the provisions of this Section 5 but not expressly provided for
by such provisions, then the Board of Directors will make an appropriate
adjustment in each Conversion Price so as to protect the rights of the holders
of Series A Preferred Stock.




                5G.   Notices.


                        (i)  Immediately upon any adjustment of the Conversion 
Price of any class of Series A Preferred Stock, the Corporation will give 
written notice thereof to all holders of such class of Series A Preferred Stock.


                        (ii)  The Corporation will give written notice to all 
holders of Series A Preferred Stock at least twenty (20) days prior to the date
on which the Corporation closes its books or takes a record (a) with respect
to any dividend or distribution upon Common Stock, (b) with respect to any pro
rata subscription offer to holders of Common Stock or (c) for determining
rights to vote with respect to any Corporate Change, dissolution or
liquidation.

proportionately decreased in the event of a split or subdivision, or
proportionately increased in the event of a combination, of the Common Stock
into a different number of securities of the same class.

                Any such mandatory conversion shall be effected at the time of
and subject to the occurrence of such a Triggering Event and upon the giving
notice of such mandatory conversion to all holders of Series A Preferred Stock

Corporation.

                (c)   Upon any such conversion pursuant to this Section or 
Section 3C, the rights of each holder of such Series A Preferred Stock as such
holder shall cease and the Person or Persons in whose name or names any
certificate or certificates for shares of Series A Preferred Stock shall be
deemed to have become the holder or holders of record of the shares of Common
Stock represented thereby.  Promptly following delivery of written notice from
the Corporation to each holder of Series A Preferred Stock that such a
conversion has occurred, each such holder shall deliver certificates
representing the shares of Series A Preferred Stock held by such holder to the
Corporation for cancellation.

taken, the date as of which the record holders of Common Stock entitled to such
dividends are to be determined.

        Section 7.  Purchase Rights.

any Options, Convertible Securities or rights to stock, warrants, securities or
other property to all record holders of any class of Common Stock (the

entitled to acquire, upon the terms applicable to such Purchase Rights, the

Rights.

execute and deliver (at the Corporation's expense) a new certificate or
certificates in exchange therefor representing in the aggregate the number of
shares of Series A Preferred Stock represented by the surrendered certificate.

such number of shares of Series A Preferred Stock as is requested by the holder
of the surrendered certificate and will be substantially identical in form to
the surrendered certificate; provided, however, that any transfer shall be
subject to any applicable restrictions on the transfer of such shares and the

                             A DELAWARE CORPORATION

"Series A Preferred Stock").  This Series A Warrant is one of the Series A
Warrants referred to as the "Series A Warrants" in the Warrant Purchase

  1. Term of Series A Warrant.  Subject to the terms and conditions set forth
herein including, without limitation, Section 12 hereof, this Series A Warrant
shall be exercisable, in whole or in part, during the term commencing on August

(the "Exercise Period"), and shall be void thereafter.

  2. Exercise Price.  The Exercise Price at which this Series A Warrant may be
exercised shall be $0.10 per share of Common Stock.

  3.   Exercise of Series A Warrant.

   (a)   Mechanics. The purchase rights represented by this Series A Warrant
are exercisable by the Holder in whole or in part, but not for less than 25,000
shares at a time (or such lesser number of shares which may then constitute the
maximum number purchasable), at any time, or from time to time, during the term
hereof as described in Section 1 above, by the surrender of this Series A
Warrant and the Notice of Exercise attached hereto as Exhibit A duly completed
and executed on behalf of the Holder, at the office of the Company (or such
other office or agency of the Company as it may designate by notice in writing
to the Holder at the address of the Holder appearing on the books of the
Company), upon payment (i) in cash or by check acceptable to the Company, (ii)
by deduction from the number of shares delivered upon exercise of the Series A
Warrant of a number of shares which has an aggregate Current Market Price (as
defined herein) on the date of exercise equal to the aggregate Exercise Price
for all shares to be purchased pursuant to this Series A Warrant, or (iii) by a
combination of (i) and (ii), of the purchase price of the shares to be
purchased.

   (b)   Certificates. This Series A Warrant shall be deemed to have been
exercised immediately prior to the close of business on the date of its
surrender for exercise as provided above, and the person entitled to receive
the shares of Common Stock issuable upon such exercise shall be treated for all
purposes as the holder of record of such shares as of the close of business on
such date.  As promptly as practicable on or after such date and in any event
within ten (10) days thereafter, the Company at its expense shall issue and
deliver to the person or persons entitled to receive the same a certificate or
certificates for the number of shares issuable upon such exercise.  In the
event that this Series A Warrant is exercised in part, the Company at its
expense will execute and deliver a new Series A Warrant of like tenor
exercisable for the number of shares for which this Series A Warrant may then
be exercised.

                                                              Purchase Agreement



   (c)   Net Issue Exercise. Notwithstanding any provisions herein to the
contrary, if the fair market value of one (1) share of Common Stock is greater
than the Exercise Price (at the date of calculation as set forth below), in
lieu of exercising this Series A Warrant for cash, the Holder may elect to
receive shares equal to the value (as determined below) of this Series A
Warrant (or the portion being exercised) by surrender of this Series A Warrant
at the principal office of the Company together with the properly endorsed
Notice of Exercise and notice of such election in which event the Company shall
issue to the Holder a number of shares of Common Stock computed using the
following formula:

    X  =   Y(A-B)
           ------
             A

  Where  X =  the number of shares of Common Stock to be issued to the Holder

         Y =  the number of shares of Common Stock purchasable under the Series
              A Warrant or, if only a portion of the Series A Warrant is being
              exercised, the portion of the Series A Warrant being exercised (at
              the date of such calculation)

         A =  the Current Market Price of one (1) share of the Company's Common
              Stock (at the date of such calculation)

         B =  Exercise Price (as adjusted to the date of such calculation)

For purposes of this Agreement, "Current Market Price" of any security means
the average of the closing prices of such security's sales on all securities
exchanges on which such security may at the time be listed, or, if there has
been no sales on any such exchange on any day, the average of the 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 in the NASDAQ System as of 4:00 P.M., New York time,
or, if on any 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 ten (10) days consisting of the day as of which "Current
Market Price" is being determined and the nine (9) consecutive business days
prior to such day.  If at any time such security is not listed on any
securities exchange or quoted in the NASDAQ System or the over-the-counter
market, the "Current Market Price" will be the fair value thereof determined
jointly by the corporation and the holders of a majority of the Series A
Warrants.

                                                              Purchase Agreement


If such parties are unable to reach agreement within a reasonable period of
time, such fair value will be determined by an independent appraiser jointly
selected by the corporation and the holders of a majority of the Series A
Warrants.  The expenses of the appraisers will be paid one-half by the Company
and one-half by the holders of the Series A Warrants (pro rata based on the
number of shares of Common Stock issuable upon exercise of the Series A
Warrants).

  4. No Fractional Shares or Scrip.  No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Series A Warrant.
In lieu of any fractional share to which the Holder would otherwise be
entitled, the Company shall make a cash payment equal to the Exercise Price
multiplied by such fraction.

  5. Replacement of Series A Warrant.  On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Series A Warrant and, in the case of loss, theft or destruction, on

Holder shall not be entitled to vote or receive dividends or be deemed the
holder of Common Stock or any other securities of the Company that may at any
time be issuable upon the exercise hereof for any purpose, nor shall anything

the contrary.

   (b)   Series A Warrant Agent. The Company may, by written notice to the

this Series A Warrant with respect to compliance with the Securities Act of
1933, as amended (the "Act"), title to this Series A Warrant may be transferred

by endorsement and delivery.

   (d)   Exchange of Series A Warrant Upon a Transfer. On surrender of this
Series A Warrant for exchange, properly endorsed on the Notice of Assignment
attached hereto and subject to the provisions of this Series A Warrant with
respect to compliance with the Act and with the limitations on assignments and
transfers contained in this Section 7, the Company at its expense shall issue
to or on the order of the Holder a new warrant or warrants of like tenor, in
the name of the Holder or as the Holder (on payment by the Holder of any
applicable transfer taxes) may direct, for the number of shares issuable upon
exercise hereof.

   (e)   Compliance with Securities Laws.

     (i)  The Holder, by acceptance hereof, acknowledges that this Series A
Warrant and the shares of Common Stock to be issued upon exercise hereof are
being acquired solely for the Holder's own account and not as a nominee for any
other party, and for investment, and that the Holder will not offer, sell or
otherwise dispose of this Series A Warrant or any shares of Common Stock to be
issued upon exercise hereof except under circumstances that will not result in
a violation of the Act or any state securities laws.  Upon exercise of this

Series A Warrant, the Holder shall, if requested by the Company, confirm in
writing, in a form satisfactory to the Company, that the shares of Common Stock
so purchased are being acquired solely for the Holder's own account, and not as
a nominee for any other party, for investment, and not with a view toward
distribution or resale.

       (ii) This Series A Warrant and all shares of Common Stock issued upon
exercise hereof shall be stamped or imprinted with a legend in substantially
the following form (in addition to any legend required by state securities
laws):

THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE

  8. Reservation of Stock.  The Company covenants that during the Exercise
Period, the Company will reserve from its authorized and unissued Common Stock
a sufficient number of shares to provide for the issuance of Common Stock upon
the exercise of this Series A Warrant and, from time to time, will take all
steps necessary to amend its Certificate of Incorporation to provide sufficient
reserves of Common Stock issuable upon exercise of this Series A Warrant.  The
Company further covenants that all shares that may be issued upon the exercise
of rights represented by this Series A Warrant, upon exercise of the rights and
payment of the Exercise Price, all as set forth herein, and will be free from
all taxes, liens and charges in respect of the issue thereof (other than taxes
in respect of any transfer occurring contemporaneously or otherwise specified
herein).  The Company agrees that its issuance of this Series A Warrant shall
constitute full authority to its officers who are charged with the duty of
executing stock certificates to execute and issue the necessary certificates
for shares of Common Stock upon the exercise of this Series A Warrant.

then outstanding) shall be deemed terminated in whole, but not in part, without
any further action by the Company; provided, the Company shall, in good faith,
use its best efforts to give notice of such termination of such aggregate
amount of Series A Warrants by giving written notice to each of the holders
thereof.  Not later than ten (10) days after receipt of any such notice, each
such holder shall surrender the Series A Warrants held thereby (pro rata based
on the number of shares of Common Stock which would be issuable upon exercise
by the holders of the Series A Warrants as calculated by the Company) to the
Company without any representation or warranty (other than that such holder has
good and valid title thereto free and clear of liens, claims, encumbrances and

shares of Series A Preferred Stock were then outstanding), plus (b) the amount
of all dividends (whether in the form of cash, securities or other properties)
that accrued (whether paid or unpaid) on one (1) share of Series A Preferred
Stock from August ___, 1995 to and including the Determination Date (or if no
share of Series A Preferred Stock is then outstanding, the amount of all

written notice to each of the holders thereof.  Not later than ten (10) days
after receipt of any such notice, each such holder shall surrender the Series A
Warrants held thereby to the Company without any representation or warranty
(other than that such holder has good and valid title thereto free and clear of
liens, claims, encumbrances and restrictions of any kind).  A "Second
Cancellation Event" shall have deemed to have occurred as of the Determination
Date if the sum of (a) the product of (x) the Current Market Price of a share
of Common Stock as of the Determination Date and (y) the number of shares of
Common Stock (including for purposes of this calculation fractional shares)

Warrant, the Holder shall not be entitled to vote or receive dividends or be
deemed the holder of Common Stock or any other securities of the Company that
may at any time be issuable upon the exercise hereof for any purpose, nor shall
anything contained herein be construed to confer upon the Holder, as such, any
of the rights of a stockholder of the Company or any right to vote for the
election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action
(whether upon any recapitalization, issuance of stock, reclassification of
stock, change of par value, or change of stock to no par value, consolidation,
merger, conveyance, or otherwise) or to receive notice of meetings, or to
receive dividends or subscription rights or otherwise until the Series B

Warrant and the shares of Common Stock to be issued upon exercise hereof are
being acquired solely for the Holder's own account and not as a nominee for any
other party, and for investment, and that the Holder will not offer, sell or
otherwise dispose of this Series B Warrant or any shares of Common Stock to be
issued upon exercise hereof except under circumstances that will not result in
a violation of the Act or any state securities laws.  Upon exercise of this
Series B Warrant, the Holder shall, if requested by the Company, confirm in
writing, in a form satisfactory to the Company, that the shares of Common Stock
so purchased are being acquired solely for the Holder's own account and not as
a nominee for any other party, for investment, and not with a view toward
distribution or resale.

     (ii) This Series B Warrant and all shares of Common Stock issued upon
exercise hereof shall be stamped or imprinted with a legend in substantially
the following form (in addition to any legend required by state securities
laws):

HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT
TO THE SECURITIES UNDER SUCH ACT OR SUCH LAWS OR UNLESS THE COMPANY HAS
RECEIVED AN OPINION OF COUNSEL, SATISFACTORY TO THE COMPANY AND ITS COUNSEL,
THAT SUCH REGISTRATION IS NOT REQUIRED.

  8. Reservation of Stock.  The Company covenants that during the Exercise
Period, the Company will reserve from its authorized and unissued Common Stock
a sufficient number of shares to provide for the issuance of Common Stock upon
the exercise of this Series B Warrant and, from time to time, will take all
steps necessary to amend its Certificate of Incorporation to provide sufficient
reserves of Common Stock issuable upon exercise of this Series B Warrant.  The
Company further covenants that all shares that may be issued upon the exercise
of rights represented by this Series B Warrant, upon exercise of the rights and
payment of the Exercise Price, all as set forth herein, and will be free from
all taxes, liens and charges in respect of the issue thereof (other than taxes
in respect of any transfer occurring contemporaneously or otherwise specified
herein).  The Company agrees that its issuance of this Series B Warrant shall
constitute full authority to its officers who are charged with the duty of
executing stock certificates to execute and issue the necessary certificates
for shares of Common Stock upon the exercise of this Series B Warrant.

   (a)   Whenever the Exercise Price or number of shares purchasable hereunder
shall be adjusted pursuant to Section 11 hereof, the Company shall issue a
certificate signed by its Chief Financial Officer setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated, and the Exercise Price and
number of shares purchasable hereunder after giving effect to such adjustment,
and shall cause a copy of such certificate to be mailed (via overnight courier)
to the holder of this Series B Warrant.

   (b)   In the event:

        (i)   the Company shall take a record of the holders of its Common
Stock (or other stock or securities at the time receivable upon the exercise of
this Series B Warrant) for the purpose of entitling them to receive any
dividend or other distribution, or any right to subscribe for or purchase any
shares of stock of any class or any other securities, or to receive any other

Company with or into another corporation, or any conveyance of all or
substantially all of the assets of the Company to another corporation, or

       (iii) of any voluntary dissolution, liquidation or winding-up of the
Company,

then, and in each such case, the Company will mail or cause to be mailed (via
overnight courier) to each holder of the Series B Warrants a notice specifying,
as the case may be, (A) the date on which a record is to be taken for the
purpose of such dividend, distribution or right, and stating the amount and
character of such dividend, distribution or right, or (B) the date on which
such reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding-up is to take place, and the time, if any
is to be fixed, as of which the holders of record of Common Stock (or such
stock or securities at the time receivable upon the exercise of this Series B
Warrant) shall be entitled to exchange their shares of Common Stock (or such
other stock or securities) for securities or other property deliverable upon
such reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding-up.  Such notice shall be mailed at least
fifteen (15) days prior to the date therein specified.

    (c)   All such notices, advices and communications shall be deemed to have
been received (i) in the case of personal delivery, on the date of such
delivery and (ii) in the case of mailing (via overnight courier), on the second
business day following the date of such mailing (or such earlier date if
received thereon).

consent of the Company and the holders of warrants representing a majority of
the shares of Common Stock issuable upon exercise of the Series B Warrants.
Any amendment effected in accordance with this Section 10 shall be binding upon
each holder of the Series B Warrants, each future holder of all such Series B
Warrants, and the Company; provided, however, no special consideration or
inducement may be given to any such holder in connection with such consent that
is not given ratably to all such holders equally and ratably in accordance with
the number of shares of Series B Warrants.  The Company shall promptly give
notice to all holders of Series B Warrants of any amendment effected in

                                                              Purchase Agreement


    (b)   No waivers of, or exceptions to, any terms, condition or provision of
this Series B Warrant, in any one or more instances, shall be deemed to be, or
construed as, a further or continuing waiver of any such term, condition or
provision.

  11.  Adjustments.   The Exercise Price and the number of shares purchasable
       hereunder are subject to adjustment from time to time as follows:

  11.1 Exercise Price.

    (a)   In order to prevent dilution of the exercise rights granted hereunder,
the Exercise Price will be subject to adjustment from time to time pursuant to
this Section 11; provided, however, there will be no adjustment of the Exercise
Price as a result of (i) issuances or deemed issuances of Common Stock for
incentive or compensatory purposes to directors, officers and employees of, and
consultants to, the Company or its Subsidiaries which are from time to time
approved by the Company's Board of Directors, including, without limitation,
grants of stock options and the issuance of Common Stock upon the exercise
thereof ("Compensatory Stock") but not exceeding, at any time prior to August
__, 1996 (or any time thereafter unless approved by the Board of Directors (or
the Compensation Committee thereof) of the Company), 3,057,000 shares of Common
Stock (net of any repurchases of such shares or options), subject to adjustment
for all subdivisions and combinations, (ii) any split, subdivision or
combination of Common Stock into a different number of securities of the same
class (subject to Section 11.5 hereof) ("Split Stock"), (iii) issuances or
deemed issuances of Common Stock upon conversion or exercise, as the case may
be, of the Series A Preferred Stock, the Series A Warrants or the Series B
Warrants (each as defined in the Warrant Purchase Agreement) ("Converted
Stock"), (iv) issuances or deemed issuances of not more than 55,000 shares of
Common Stock to David K. Vanco pursuant to that certain Agreement and Plan of
Merger among the Company, Vanco Business Management, Inc. and David K. Vanco,
as amended (subject to adjustment for all subdivisions and combinations)
("Vanco Stock") or (v) any distribution or granting of stock or other
securities or property (other than cash) of the Company, by way of dividend, in
accordance with Section 11.6 hereof ("Purchase Stock", and together with
Converted Stock, Compensatory Stock, Vanco Stock and Split Stock, the "Excluded
Stock").

    Anything herein to the contrary notwithstanding, no adjustment in the
Exercise Price shall be required unless such adjustment, either by itself or
with other adjustments not previously made, would require a change of at least
$.10 in such price; provided, however, that any adjustment which by reason of
this sentence is not required to be made shall be carried forward and taken
into account in any subsequent adjustment.

                                                              Purchase Agreement



       (b)  If and whenever, after the date hereof, the Company issues or sells,
or in accordance with Section 11.2 is deemed to have issued or sold, any shares
of its Common Stock (other than Excluded Stock) for a consideration per share
less than the Exercise Price in effect immediately prior to the time of such
issuance or sale, then forthwith upon such issuance or sale the Exercise Price
will be reduced to the exercise price determined by dividing (i) the sum of (1)
the product derived by multiplying the Exercise Price in effect immediately
prior to such issuance or sale times the number of shares of Common Stock
Deemed Outstanding immediately prior to such issuance or sale, plus (2) the
consideration, if any, received or deemed received by the Company upon such
issuance or sale, by (ii) the number of shares of Common Stock Deemed
Outstanding immediately prior to such issuance or sale plus the number of
shares of Common Stock issued or deemed to have been issued in such sale
pursuant to this Section 11.  "Common Stock Deemed Outstanding" means, at any
given time, the number of shares of Common Stock actually outstanding at such
time, plus, the number of shares of Common Stock issuable upon the exercise,
conversion or exchange of all Options or Convertible Securities then
outstanding, whether or not they are actually exercisable, convertible or
exchangeable at such time (including, without limitation, the Series A
Preferred Stock).

   11.2.  Effect on Exercise Prices of Certain Events.

          For purposes of determining the adjusted Exercise Price under Section
11.1(ii), the following will be applicable:

       (a)  Issuance of Rights or Options.  If the Company in any manner grants,
  issues or sells any right, warrant or option to subscribe for or to purchase
  Common Stock or any stock or other securities convertible into or
  exchangeable for Common Stock (such rights, warrants or options being herein
  called "Options," and such convertible or exchangeable stock or securities
  being herein called "Convertible Securities") (other than Excluded Stock) and
  the price per share for which Common Stock is issuable upon the exercise of
  such Options or upon conversion or exchange of any such Convertible
  Securities is less than the Exercise Price in effect immediately prior to the
  time of the granting, issuance or sale 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 amount of such
  Convertible Securities issuable upon the exercise of such Options shall be
  deemed to be outstanding and to have been issued and sold by the Company at
  the time of the granting of such Options for such price per share.  For
  purposes of this Section, the "price per share for which Common Stock is
  issuable" shall be 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

                                                              Purchase Agreement


  minimum aggregate amount of additional consideration payable to the Company
  upon exercise of all such Options, plus in the case of such Options which
  relate to Convertible Securities, the minimum aggregate amount of additional
  consideration, if any, payable to the Company upon the issuance or sale of
  such Convertible Securities and the conversion or exchange thereof, 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 all such Convertible
  Securities issuable upon the exercise of such Options.  No further adjustment
  of the Exercise Price shall be made when Convertible Securities are actually
  issued upon the exercise of such Options or when Common Stock is actually
  issued upon the exercise of such Options or the conversion or exchange of
  such Convertible Securities.

        (b)  Issuance of Convertible Securities.  If the Company in any manner
  issues or sells any Convertible Securities (other than Excluded Stock) and
  the price per share for which Common Stock is issuable upon conversion or
  exchange thereof is less than the Exercise Price in effect immediately prior
  to the time of such issue or sale, then the maximum number of shares of
  Common Stock issuable upon conversion or exchange of such Convertible
  Securities shall be deemed to be outstanding and to have been issued and sold
  by the Company at the time of the issuance or sale of such Convertible
  Securities for such price per share.  For the purposes of this Section, the
  "price per share for which Common Stock is issuable" shall be determined by
  dividing (A) the total amount received or receivable by the Company as
  consideration for the issue 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 thereof, by (B) the total maximum
  number of shares of Common Stock issuable upon the conversion or exchange of
  all such Convertible Securities.  No further adjustment of the Exercise Price
  shall be made when Common Stock is actually issued upon the conversion or
  exchange of such Convertible Securities, and if any such issue or sale of
  such Convertible Securities is made upon exercise of any Options for which
  adjustments of the Exercise Price had been or are to be made pursuant to
  other provisions of this Section 11, no further adjustment of the Exercise
  Price shall be made by reason of such issue or sale.

        (c)  Change in Option Price or Conversion Rate.  If the purchase price
  provided for in any Option, the additional consideration (if any) payable
  upon the issue, conversion or exchange of any Convertible Security, or the
  rate at which any Convertible Security is convertible into or exchangeable
  for Common Stock change at any time, and such change is not due solely to the
  operation of anti-dilution provisions similar in nature

  to those set forth in this Section 11, the Exercise Price in effect at the
  time of such change shall be readjusted to the Exercise Price which would
  have been in effect at such time had such Option or Convertible Security
  originally provided for such changed purchase price, additional consideration
  or changed conversion rate, as the case may be, at the time initially
  granted, issued or sold.

       (d)  Treatment of Expired Options and Unexercised Convertible Securities.
  Upon the expiration of any Option or the termination of any right to convert
  or exchange any Convertible Security without the exercise of any such Option
  or right, the Exercise Price then in effect hereunder will be adjusted to the
  Exercise Price which would have been in effect at the time of such expiration
  or termination had such Option or Convertible Security, to the extent
  outstanding immediately prior to such expiration or termination, never been
  issued.

       (e)  Calculation of Consideration Received.  If any Common Stock, Option
  or Convertible Security is issued or sold or deemed to have been issued or
  sold for cash, the consideration received therefor will be deemed to be the
  gross amount received by the Company therefor.  If any Common Stock, Options
  or Convertible Securities are issued or sold for a consideration other than
  cash, the amount of the consideration other than cash received by the Company
  will be the fair value of such consideration, except where such consideration
  consists of securities, in which case the amount of consideration received by
  the Company will be the Current Market Price thereof as of the date of
  receipt.  If any Common Stock, Option or Convertible Security is issued in
  connection with any merger in which the Company is the surviving Company, the
  amount of consideration therefor will be deemed to be the fair value of such
  portion of the net assets and business of the non-surviving Company as is
  attributable to such Common Stock, Options or Convertible Securities, as the
  case may be. The fair value of any consideration other than cash and
  securities will be determined jointly by the Company and the holders of a
  majority of the outstanding Series B Warrants.  If such parties are unable to
  reach agreement within ten (10) days after the occurrence of an event
  requiring valuation (the "Valuation Event"), the fair value of such
  consideration will be determined by an independent appraiser jointly selected
  by the Company and the holders of a majority of the outstanding Series B
  Warrants; provided if such parties are unable to reach agreement upon the
  selection of an independent appraiser within fifteen (15) days after the
  Valuation Event, within twenty-five (25) days after the Valuation Event, the
  Company and the holders of a majority of the Series B Warrants then
  outstanding will each choose a qualified independent appraiser reasonably
  acceptable to the other party and each such appraiser will deliver in writing
  its

                                                              Purchase Agreement


  determination of the fair value of such consideration.  If the difference
  between the two appraisals is 10% or less of the lower amount, the fair value
  will be the average of such two appraisals.  If the difference between the
  two appraisals is greater than 10% of the lower amount, the two (2)
  appraisers will, within thirty-five (35) days after the Valuation Event,
  jointly choose a third qualified independent appraiser.  Within forty-five
  (45) days after the Valuation Event, the third appraiser will deliver its
  determination of fair value and the final determination of the fair value of
  such consideration will be equal to the average of the two (2) appraisals
  which are nearest to each other.  The expenses of the appraisers will be paid
  one-half by the Company and one-half by the holders of the Series B Warrants
  (pro rata based on the number of shares of Common Stock which would be
  issuable upon exercise by the holders of the Series B Warrants).

      For purposes of this Agreement, "Current Market Price" of any security 
  means the average of the closing prices of such security's sales on all 
  securities exchanges on which such security may at the time be listed, or, if
  there has been no sales on any such exchange on any day, the average of the 
  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 in the NASDAQ System as of 
  4:00 P.M., New York time, or, if on any 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 ten (10) days consisting of the day 
  as of which "Current Market Price" is being determined and the nine (9) 
  consecutive business days prior to such day.  If at any time such security is
  not listed on any securities exchange or quoted in the NASDAQ System or the
  over-the-counter market, the "Current Market Price" will be the fair value
  thereof determined jointly by the corporation and the holders of a majority
  of the Series B Warrants.  If such parties are unable to reach agreement
  within a reasonable period of time, such fair value will be determined by an
  independent appraiser jointly selected by the corporation and the holders of
  a majority of the Series B Warrants.  The expenses of the appraisers will be
  paid one-half by the Company and one-half by the holders of the Series B
  Warrants (pro rata based on the number of shares of Common Stock issuable
  upon exercise of the Series B Warrants).

            (f)  Integrated Transactions.  In case any Option is issued in 
  connection with the issue or sale of other securities of the Company, together
  comprising one integrated transaction in which no specific consideration is
  allocated to such Option by

                                                              Purchase Agreement


  the parties thereto, the Option will be deemed to have been issued for a
  consideration of $.01.

     (g)  Treasury Shares.  The number of shares of Common Stock outstanding at
  any given time does not include shares owned or held by or for the account of
  the Company or any Subsidiary, and the disposition of any shares so owned or
  held will be considered an issue or sale of Common Stock.

     (h)  Record Date.  If the Company takes a record of the holders of Common
  Stock for the purpose of entitling them (i) to receive a dividend or other
  distribution payable in Common Stock, Options or Convertible Securities or
  (ii) to subscribe for or purchase Common Stock, Options or Convertible
  Securities, then such record date will be deemed to be the date of the issue
  or sale of the shares of Common Stock deemed to have been issued or sold upon
  the declaration of such dividend or upon the making of such other
  distribution or the date of the granting of such right of subscription or
  purchase, as the case may be.

  11.3 Merger, Sale of  Assets, etc.  If at any time while this Series B
Warrant or any portion thereof, is outstanding and unexpired there shall be (i)
a reorganization (other than a combination, reclassification, exchange or
subdivision of shares otherwise provided for herein), (ii) a merger or
consolidation of the Company with or into another corporation in which the
Company is not the surviving entity but the shares of the Company's capital
stock outstanding immediately prior to the merger are converted by virtue of
the merger into other property, whether in the form of securities, cash, or
otherwise, or (iii) a sale or transfer of the Company's properties and assets
as, or substantially as, an entirety to any other person, then, as a part of
such reorganization, merger, consolidation, sale or transfer, lawful provision
shall be made so that the holder of this Series B Warrant shall thereafter be
entitled to receive upon exercise of this Series B Warrant, during the period
specified herein and upon payment of the Exercise Price then in effect, the
number of shares of stock or other securities or property of the successor
corporation resulting from such reorganization, merger, consolidation, sale or
transfer that a holder of the shares deliverable upon exercise of this Series B
Warrant would have been entitled to receive in such reorganization,
consolidation, merger, sale or transfer if this Series B Warrant had been
exercised immediately before such reorganization, merger, consolidation, sale
or transfer. The foregoing provisions of this Section 11.3 shall similarly
apply to successive reorganizations, consolidations, mergers, sales and
transfers and to the stock or securities of any other corporation that are at
the time receivable upon the exercise of this Series B Warrant.  If the
per-share consideration payable to the holder hereof for shares in connection
with any such transaction is in a form other than cash or marketable
securities, then the value of such

                                                              Purchase Agreement


consideration shall be determined pursuant to the provisions of Section
11.2(ii)(e).  In all events, appropriate adjustment (as determined in good
faith by the Company's Board of Directors) shall be made in the application of
the provisions of this Series B Warrant with respect to the rights and
interests of the Holder after the transaction, to the end that the provisions
of this Series B Warrant shall be applicable after that event, as near as
reasonably may be, in relation to any shares or other property deliverable
after that event upon exercise of this Series B Warrant.

  11.4 Reclassification, etc.  If the Company, at any time while this Series B
Warrant, or any portion thereof, remains outstanding and unexpired by
reclassification of securities or otherwise, shall change any of the securities
as to which purchase rights under this Series B Warrant exist into the same or
a different number of securities of any other class or classes, this Series B
Warrant shall thereafter represent the right to acquire such number and kind of
securities as would have been issuable as the result of such change with
respect to the securities that were subject to the purchase rights under this
Series B Warrant immediately prior to such reclassification or other change and
the Exercise Price therefor shall be appropriately adjusted, all subject to
further adjustment as provided in this Section 11.4.

  11.5 Split, Subdivision or Combination of  Shares.  If the Company at any
time while this Series B Warrant, or any portion thereof, remains outstanding
and unexpired shall split, subdivide or combine the securities as to which
purchase rights under this Series B Warrant exist, into a different number of
securities of the same class, the Exercise Price for such securities shall be
proportionately decreased in the case of a split or subdivision or
proportionately increased in the case of a combination.

  11.6.  Adjustments for Dividends in Stock or Other Securities or Property.
If while this Series B Warrant, or any portion hereof, remains outstanding and
unexpired the holders of the securities as to which purchase rights under this
Series B Warrant exist at the time shall have received, or, on or after the
record date fixed for the determination of eligible stockholders, shall have
become entitled to receive, without payment therefor, other or additional stock
or other securities or property (other than cash) of the Company, by way of
dividend, then and in each case, this Series B Warrant shall represent the
right to acquire, in addition to the number of shares of the security
receivable upon exercise of this Series B Warrant, and without payment of  any
additional consideration therefor, the amount of such other or additional stock
or other securities or property (other than cash) of the Company, by way of
dividend, that such holder would hold on the date of such exercise had it been
the holder of record of the security receivable upon exercise of this Series B
Warrant on the date thereof and had thereafter, during the period from the date
thereof to and including the date of such exercise, retained such shares

seek to avoid the observance or performance of any of the terms to be observed
or performed hereunder by the Company, but will at all times in good faith
assist in the carrying out of all the provisions of this Section 11 and in the
taking of all such action as may be necessary or appropriate in order to
protect the rights of the Holders of this Series B Warrant against impairment.

Warrant, the Holder agrees to be bound and is subject to the rights,
limitations and preferences set forth in the Registration Rights Agreement.

  13.  Miscellaneous.

deemed modified to the extent necessary to make it enforceable by such court or
agency.  If any such provision is not enforceable as set forth in the preceding

   2.  Registration Under Securities Act.

   2.1.  Registration on Request.  (a) Request.  At any time on or after the
six-month anniversary of the date hereof and upon the written request of one
(1) or more holders (the "Initiating Holders") of Registrable Securities
holding not less than 33% of the Registrable Securities then held by the
holders of Registrable Securities that the Company effect the registration
under the Securities Act of all or part of such Initiating Holders' Registrable
Securities, the Company will promptly give written notice of such requested
registration to all registered holders of Registrable Securities, and thereupon
the Company will use its best efforts to effect the registration under the
Securities Act, including by means of a shelf registration pursuant to Rule 415
under the Securities Act if so requested in such request and if the Company is
then eligible to use such a registration (a "Shelf Registration"), of

                  (i)  the Registrable Securities which the Company has been
requested to register by such Initiating Holders, and

                 (ii)  all other Registrable Securities which the Company has
been requested to register by the holders thereof (such holders together with
the Initiating Holders are hereinafter referred to as the "Selling Holders") by
written request given to the Company within fifteen (15) days after the giving
of such written notice by the Company,

all to the extent required to permit the disposition of the Registrable
Securities so as to be registered; provided, however, the Company shall not be
required to file a registration statement under this Section 2.1 if (i) less
than $1,000,000 of Registrable Securities are to be included in such
registration, (ii) any registration statement (other than on Form S-4 or S-8 or
any successor or similar forms are filed in connection with an exchange offer
or any offering of securities solely to the Company's existing stockholders)
covering securities to be sold by the Company

                                                              Purchase Agreement


has been filed and not withdrawn or has been declared effective within the
preceding one hundred eighty (180) days if the preceding registration was on
Form S-3 or two hundred seventy (270) days if the preceding registration was on
Form S-1 or S-2 or (iii) the Company shall furnish to the Selling Holders a
certificate signed by the Chief Executive Officer of the Company stating that
in the good faith judgment of the Board of Directors it would be materially
detrimental to the Company or its stockholders for a registration statement to
be filed in the near future, in which event, with respect to (iii) above, the
Company's obligation to use its best efforts to register, qualify or comply
under this Section 2.1 shall be deferred for a period not to exceed ninety (90)
days, such right to delay a request not to be exercised by the Company more
than once in any twelve-month period.

                 (b)      Registration Statement Form.  Registrations under
this Section 2.1 shall be on such appropriate registration form of the
Commission as shall be selected by the Company.  The Company agrees to include
in any such registration statement all information which, in the opinion of
counsel to the Company, is required to be included.

                 (c)      Expenses.  The Company will pay the Registration
Expenses in connection with any registration requested pursuant to this Section
2.1, provided, the Company shall not be required to pay the Registration
Expenses of (i) any registration proceeding begun pursuant to this Section 2.1,
the request of which has been subsequently withdrawn by the Selling Holders,
unless the holders of a majority of the Registrable Securities agree that such
request will constitute a demand registration pursuant to Section 2.1 or (ii)
any registration in connection with which the Selling Holders assumed
responsibility for payment of the Registration Expenses.

                 (d)      Effective Registration Statement.  A registration
requested pursuant to this Section 2.1 shall not be deemed to have been
effected (i) unless a registration statement with respect thereto has become
effective, (ii) if after it has become effective, such registration is
interfered with by any stop order, injunction or other order or requirement of
the Commission or other governmental agency or court for any reason not
attributable to the Selling Holders and has not promptly thereafter become
effective, or (iii) if the conditions to closing specified in the underwriting
agreement, if any, entered into in connection with such registration are not
satisfied or waived, other than by reason of a failure on the part of the
Selling Holders.

                 (e)      Selection of Underwriters.  The underwriter or
underwriters of each underwritten offering of the Registrable Securities so to
be registered shall be selected by the Company.

                                                              Purchase Agreement


                 (f)      Priority in Requested Registration.  If the managing
underwriter of any underwritten offering shall advise the Company in writing
(with a copy to each Selling Holder) that, in its opinion, the number of
securities requested to be included in such registration exceeds the number
which can be sold in such offering within a price range acceptable to the
Selling Holders holding not less than a majority of the Registrable Securities
requested to be included in such registration, the Company will include in such
registration, to the extent of the number which the Company is so advised can
be sold in such offering, Registrable Securities requested to be included in
such registration and other securities requested to be included in such
registration pursuant to registration rights contained in agreements existing
as of the date hereof and registration rights granted after the date hereof in
accordance with Section 5 ("Pari Passu Rights"), pro rata among the Selling
Holders and other holders requesting such registration according to the total
number of Registrable Securities and other securities requested to be
registered by each Selling Holder or other holder, as the case may be.

                 (g)      Limitations on Registration on Request.
Notwithstanding anything in this Section 2.1 to the contrary, in no event will
the Company be required to effect, in the aggregate, without regard to the
holder of Registrable Securities making such request, more than two (2)
registrations with respect to an underwritten public offering (a "Requested
Underwritten Offering") pursuant to this Section 2.1; provided, however, in the
event (i) the Selling Holders assume in writing responsibility for payment of
the Registration Expenses, whether or not such registration is ultimately
effected, (ii) the registration occurs in connection with a Triggering Event
(as defined in the Certificate of Designation) or (iii) the Company exercises
its pre-emptive right pursuant to Section 2.2(h), any such registration shall
not be treated as a Requested Underwritten Offering for purposes of the
limitations set forth in this Section 2.1(g).

                 (h)      Pre-emption.     The Company will have the right to
pre-empt one (1) (but no more than one) Requested Underwritten Offering
pursuant to this Section 2.1 with a primary registration by delivering written
notice of such intention to the Initiating Holders within five (5) business
days after the Company has received a request for such Requested Underwritten
Offering; provided, (i) the Company shall deliver to the Initiating Holders a
plan of the Board of Directors of the Company with respect to such primary
registration no later than thirty (30) days after the Company has received a
request for such Requested Underwritten Offering and (ii) such primary
registration shall take effect no later than one hundred and eighty (180) days
after such Requested Underwritten Offering has occurred.  In the ensuing
primary registration, the holders of Registrable Securities will have such
piggyback rights as are set forth in Section 2.2.

                                                              Purchase Agreement


                 2.2.     Incidental Registration.  (a) Right to Include
Registrable Securities.  If the Company at any time proposes to register any of
its securities under the Securities Act by registration on Forms S-1, S-2 or
S-3 or any successor or similar form(s), whether or not for sale or for its own
account, it will each such time give prompt written notice to all registered
holders of Registrable Securities of its intention to do so and of such
holders' rights under this Section 2.2.  Upon the written request of any such
holder (a "Requesting Holder") made as promptly as practicable and in any event
within fifteen (15) days after the receipt of any such notice (which request
shall specify the Registrable Securities intended to be disposed of by such
Requesting Holder), the Company will use its best efforts to effect the
registration under the Securities Act of all Registrable Securities which the
Company has been so requested to register by the Requesting Holders thereof;
provided, however, that if, at any time after giving written notice of its
intention to register any securities and prior to the effective date of the
registration statement filed in connection with such registration, the Company
shall determine for any reason not to register or to delay registration of such
securities, the Company may, at its election, give written notice of such
determination to each Requesting Holder of Registrable Securities and (i) in
the case of a determination not to register, shall be relieved of its
obligation to register any Registrable Securities in connection with such
registration (but not from any obligation of the Company to pay the
Registration Expenses in connection therewith), without prejudice, however, to
the rights of any holder or holders of Registrable Securities entitled to do so
to request that such registration be effected as a registration under Section
2.1, subject to Section 2.1(g), and (ii) in the case of a determination to
delay registering, shall be permitted to delay registering any Registrable
Securities, for the same period as the delay in registering such other
securities.  No registration effected under this Section 2.2 shall relieve the
Company of its obligation to effect any registration upon request under Section
2.1.  Subject to Section 2.1(g), the Company will pay all Registration Expenses
in connection with registration of Registrable Securities requested pursuant to
this Section 2.2.

                 (b)      Priority in Incidental Registrations.  If the
managing underwriter of any underwritten offering shall inform the Company by
letter with a copy to the holder or holders of Registrable Securities of its
belief that the number or type of Registrable Securities requested to be
included in such registration would materially adversely affect such offering,
then the Company will include in such registration, to the extent of the number
and type which the Company is so advised can be sold in (or during the time of)
such offering, first, all securities proposed by the Company to be sold for its
own account  in a primary offering or by the holder requesting such
registration in a secondary offering, and second, such Registrable Securities
and other securities with Pari Passu Rights requested to be included in such
registration, such Registrable Securities and other securities to be included
in such registration pro rata among the Requesting Holders and other holders
according to the total number of Registrable Securities

                                                              Purchase Agreement


requested to be included in such registration by each such Requesting Holder or
other holder, as the case may be, and third, all other securities requested to
be included in such registration.

                 (c)      Selection of Underwriters.  If a registration
pursuant to this Section 2.2 involves an underwritten offering, the underwriter
or underwriters thereof shall be selected by the Company.  Each Requesting
Holder agrees that it will sell all of its Registrable Securities to be
included in such registration to the underwriter or underwriters selected by
the Company pursuant to this Section 2.2(c) on the same terms and conditions as
are applicable to the Company or other sellers of the same securities
thereunder, and at the same price as any Registrable Securities to be sold by
the Company or any such other sellers thereunder.

                 2.3.     Registration Procedures.  If and whenever the Company
is required to use its best efforts to effect the registration of any
Registrable Securities under the Securities Act as provided in Sections 2.1 and
2.2, the Company will as expeditiously as practicable:

                  (i)  prepare and file with the Commission the requisite
registration statement to effect such registration and thereafter use its best
efforts to cause such registration statement to become effective; provided,
however, that the Company may discontinue any registration of its securities
which are not Registrable Securities (and, under the circumstances specified in
Section 2.2(a), its securities which are Registrable Securities), at any time
prior to the effective date of the registration statement relating thereto;

                 (ii)  prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in
connection therewith as may be necessary to keep such registration statement
effective and to comply with the provisions of the Securities Act with respect
to the disposition of all Registrable Securities covered by such registration
statement for such period as shall be required for the disposition of all of
such Registrable Securities; provided, however, that, such period need not
exceed twelve (12) months with respect to any Shelf Registration and ninety
(90) days with respect to any other registration statement;

                (iii)  furnish to each seller of Registrable Securities covered
by such registration statement, such number of conformed copies of such
registration statement and of each amendment and supplement thereto (in each
case including all exhibits), such number of copies of the prospectus contained
in such registration statement (including each preliminary prospectus and any
summary prospectus) and any other prospectus filed under Rule 424 under the
Securities Act, in conformity with the requirements of the Securities Act, and
such other documents as such seller may reasonably request;

                                                              Purchase Agreement



                 (iv)  use its best efforts (A) to register or qualify all
Registrable Securities and other securities covered by such registration
statement under such other securities or blue sky laws of such States of the
United State of America where an exemption is not available and as the sellers
of Registrable Securities covered by such registration statement shall
reasonably request, (B) to keep such registration or qualification in effect
for so long as such registration statement remains in effect, and (C) to take
any other action which may be reasonably necessary or advisable to enable such
sellers to consummate the disposition in such jurisdictions of the securities
to be sold by such sellers, except that the Company shall not for any such
purpose be required to qualify generally to do business as a foreign
corporation in any jurisdiction wherein it would not but for the requirements
of this subdivision (iv) be obligated to be so qualified, to consent to general
service of process in any such jurisdiction or subject itself to taxation in
any such jurisdiction;

                  (v)  use its best efforts to cause all Registrable Securities
covered by such registration statement to be registered with or approved by
such other Federal or state governmental agencies or authorities as may be
necessary in the opinion of counsel to the Company to enable the sellers
thereof to consummate the disposition of such Registrable Securities;

                 (vi)  furnish to each seller of Registrable Securities a
signed counterpart, addressed to each such seller, of:

                 (A)      an opinion of counsel for the Company, and

                 (B)      a "comfort" letter signed by the independent public
accountants who have certified the Company's financial statements included or
incorporated by reference in such registration statement,

covering substantially the same matters with respect to such registration
statement (and the prospectus included therein) and, in the case of the
accountants' comfort letter, with respect to events subsequent to the date of
such financial statements as are customarily covered in opinions of issuer's
counsel and in accountants' comfort letters delivered to the underwriters in
underwritten public offerings of securities (and dated the dates such opinions
and comfort letters are customarily dated);

                 (vii)    notify each seller of Registrable Securities covered
by such registration statement, at any time when a prospectus relating thereto
is required to be delivered under the Securities Act, upon discovery that, or
upon the happening of any event as a result of which,

the prospectus included in such registration statement, as then in effect,
includes a statement of a material fact or omits to state any material fact
required to be stated therein or necessary to make the statements therein not
misleading, in the light of the circumstances under which they were made, and
at the request of any such seller promptly prepare and furnish to it a
reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such securities, such prospectus shall not include an untrue
statement of material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in
the light of the circumstances under which they were made;

                 (viii)   otherwise use its best efforts to comply with all
applicable rules and regulations of the Commission, and make available to its
security holders, as soon as reasonably practicable, an earnings statement
covering the period of at least twelve (12) months, but not more than eighteen
(18) months, beginning with the first full calendar month after the effective
date of such registration statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act, and promptly furnish to each
such seller of Registrable Securities a copy of any amendment or supplement to
such registration statement or prospectus;

                 (ix)     provide and cause to be maintained a transfer agent
and registrar for all Registrable Securities covered by such registration
statement from and after a date not later than the effective date of such
registration; and

                 (x)      use its best efforts to list all Registrable
Securities covered by such registration statement on any national securities
exchange (including the NASDAQ National Market) on which Registrable Securities
covered by such registration statement are then listed.

The Company may require each seller of Registrable Securities as to which any
registration is being affected to furnish the Company such information
regarding such seller and the distribution of such securities as the Company
may from time to time reasonably request in writing.

         Each holder of Registrable Securities agrees by acquisition of such
Registrable Securities that upon receipt of any notice from the Company of the
happening of any event of the kind described in subdivision (vii) of this
Section 2.3, such holder will forthwith discontinue such holder's disposition
of Registrable Securities pursuant to the registration statement relating to
such Registrable Securities until such holder's receipt of the copies of the
supplemented or amended prospectus contemplated by subdivision (vii) of this
Section 2.3 and, if so directly by the Company, will deliver to the Company (at
the Company's expense) all copies, other than

permanent file copies, then in such holder's possession of the prospectus
relating to such Registrable Securities current at the time of receipt of such
notice.

                 2.4.     Underwritten Offerings.  (a)  Requested Underwritten
Offerings.  If requested by the underwriters for any underwritten offering by
holders of Registrable Securities pursuant to a registration requested under
Section 2.1, the Company will use reasonable efforts to enter into an
underwriting agreement with such underwriters for such offering, such agreement
to be reasonably satisfactory in substance and form to the Company, the holders
of not less than a majority of the Registrable Securities to be included in
such registration and the underwriters and to contain such representations and
warranties by the Company and such other terms as are generally prevailing in
agreements of that type, including, without limitation, indemnities to the
effect and to the extent provided in Section 2.5.  The holders of the
Registrable Securities proposed to be distributed by such underwriters will
cooperate with the Company in the negotiation of the underwriting agreement.
Such holders of Registrable Securities shall be parties to such underwriting
agreement and may, at their option, require that any or all of the
representations and warranties by, and the other agreements on the part of, the
Company to and for the benefit of such underwriters shall also be made to and
for the benefit of such holders of Registrable Securities and that any or all
of the conditions precedent to the obligations of such underwriters under such
underwriting agreement be conditions precedent to the obligations of such
holders of Registrable Securities.

                 (b)      Incidental Underwritten Offerings.  If the Company
proposes to register any of its securities under the Securities Act as
contemplated by Section 2.2 and such securities are to be distributed by or
through one or more underwriters, subject to Section 2.2, the Company will if
requested by any Requesting Holder of Registrable Securities use its best
efforts to arrange for such underwriters to include all the Registrable
Securities to be offered and sold by such Requesting Holder among the
securities of the Company to be distributed by such underwriters.  The holders
of Registrable Securities to be distributed by such underwriters shall be
parties to the underwriting agreement between the Company and such underwriters
and may, at their option, require that any or all of the representations and
warranties by, and the other agreements on the part of, the Company to and for
the benefit of such underwriters shall also be made to and for the benefit of
such holders of Registrable Securities and that any or all of the conditions
precedent to the obligations of such underwriters under such underwriting
agreement be conditions precedent to the obligations of such holders of
Registrable Securities.

                 (c)      No Person may participate in any registration
hereunder which is underwritten unless such Person (A) agrees to sell such
Person's securities on the basis provided

hereunder to approve such arrangements and (B) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents required under the terms of such underwriting arrangements.

                 2.5.     Indemnification.  (a) Indemnification by the Company.
In the event of any registration of any securities of the Company under the
Securities Act, the Company will, and hereby does, indemnify and hold harmless,
in the case of any registration statement filed pursuant to Section 2.1 or 2.2,
each seller of any Registrable Securities covered by such registration
statement, each such seller's stockholders, directors, officers, partners,
agents and affiliates and each other person who participates as an underwriter
in the offering or sale of such securities and each other person, if any, who
controls such seller or any such underwriter within the meaning of the
Securities Act, against any losses, claims, damages or liabilities, joint and
several, to which such seller or any such stockholder, director, officer,
partner, agent or affiliate or underwriter or controlling person may become
subject under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions or proceedings, whether commenced or
threatened, in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in any
registration statement under which such securities were registered under the
Securities Act, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto, or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein in light of the
circumstances in which they were made not misleading, and the Company will
reimburse such seller and each such stockholder, director, officer, partner,
agent or affiliate, underwriter and controlling person for any legal or any
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, liability, action or proceeding; provided,
however, that the Company shall not be liable in any such case to the extent
that any such loss, claim, damage, liability (or action or proceeding in
respect thereof) or expense arises out of or is based upon an untrue statement
or alleged untrue statement or omission or alleged omission made in such
registration statement, any such preliminary prospectus, final prospectus,
summary prospectus, amendment or supplement in reliance upon and in conformity
with written information furnished to the Company by or on behalf of such
seller or underwriter, as the case may be, specifically for use in the
preparation thereof and provided further that the Company shall not be liable
to any person who participates as an underwriter in the offering or sale of
Registrable Securities or any other person, if any, who controls such
underwriter within the meaning of the Securities Act, in any such case to the
extent that any such loss, claim, damage, liability (or action or proceeding in
respect thereof) or expense arises out of such person's failure to send or give
a copy of the final prospectus, as the same may be then supplemented or
amended, to the person

asserting an untrue statement or alleged untrue statement or omission or
alleged omission at or prior to the written confirmation of the sale of
Registrable Securities to such person if such statement or omission was
corrected in such final prospectus.  Such indemnity shall remain in full force
and effect regardless of any investigation made by or on behalf of such seller
or any such stockholder, director, officer, partner, agent or affiliate or
controlling person or underwriter and shall survive the transfer of such
securities by such seller.

                 (b)  Indemnification by the Sellers.  As a condition to
including any Registrable Securities in any registration statement, the Company
shall have received an undertaking reasonably satisfactory to it from the
prospective seller of such Registrable Securities, to indemnify and hold
harmless (in the same manner and to the same extent as set forth in subdivision
(a) of this Section 2.5) the Company and each director of the Company, each
officer of the Company and each other person, if any, who controls the Company
within the meaning of the Securities Act, with respect to any statement or
alleged statement in or omission or alleged omission from such registration
statement, any preliminary prospectus, final prospectus or summary prospectus
contained therein, or any amendment or supplement thereto, if such statement or
alleged statement or omission or alleged omission was made in reliance upon and
in conformity with written information furnished to the Company specifically
for use in the preparation of such registration statement, preliminary
prospectus, final prospectus, summary prospectus, amendment or supplement.
Such indemnity shall remain in full force and effect, regardless of any
investigation made by or on behalf of the Company or any such director, officer
or controlling person and shall survive the transfer of such securities by such
seller.

                 (c)  Notices of Claims, etc.  Promptly after receipt by an
indemnified party of notice of the commencement of any action or proceeding
involving a claim referred to in the preceding subdivisions of this Section
2.5, such indemnified party will, if a claim in respect thereof is to be made
against an indemnifying party, give written notice to the latter of the
commencement of such action; provided, however, that the failure of any
indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under the preceding subdivisions of this
Section 2.5, except to the extent that the indemnifying party is actually
prejudiced by such failure to give notice.  If any such action is brought
against an indemnified party, the indemnifying party shall be entitled to
participate in and, unless in such indemnified party's reasonable judgment a
conflict of interest between such indemnified and indemnifying parties may
exist in respect of such claim, to assume the defense thereof, jointly with any
other indemnifying party similarly notified to the extent that it may wish,
with counsel reasonably satisfactory to such indemnified party, and after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party shall not be liable to
such indemnified party for any legal or other expenses subsequently

incurred by the latter in connection with the defense thereof.  No indemnifying
party shall be liable for any settlement of any action or proceeding effected
without its written consent (which consent shall not be unreasonably withheld).

                 (d)  Contribution.  If the indemnification provided for in
this Section 2.5 shall for any reason be held by a court to be unavailable to
an indemnified party under subdivision (a) or (b) hereof in respect of any
loss, claim, damage or liability, or any action in respect thereof, then, in
lieu of the amount paid or payable under subdivision (a) or (b) hereof, the
indemnified party and the indemnifying party under subdivision (a) or (b)
hereof shall contribute to the aggregate losses, claims, damages and
liabilities (including legal or other expenses as they are reasonably incurred
in connection with investigating or defending the same), (i) in such proportion
as is appropriate to reflect the relative fault of the Company and the
prospective sellers of Registrable Securities covered by the registration
statement which resulted in such loss, claims, damage or liability, or action
in respect thereof, with respect to the statements or omissions which resulted
in such loss, claims, damage or liability, or action in respect thereof, as
well as any other relevant equitable considerations or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such
proportion as shall be appropriate to reflect the relative benefits received by
the Company and such prospective sellers from the offering of the securities
covered by such registration statement.  No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  Such prospective sellers' obligations to
contribute as provided in this subdivision (d) are several in such proportion
as is appropriate to reflect the relative fault of each of the prospective
sellers, as well as any other relevant equitable consideration, and not joint;
provided, however, that if such allocation is not permitted by applicable law,
the prospective sellers' obligations to contribute shall be in proportion to
the relative value of their respective registrable securities covered by such
registration statement.  In addition, no person shall be obligated to
contribute hereunder any amounts in payment for any settlement of any action or
claim effected without such person's consent, which consent shall not be
unreasonably withheld.

                 (e)  Other Indemnification.  Indemnification and contribution
similar to that specified in the preceding subdivisions of this Section 2.5
shall be given by the Company and each seller of Registrable Securities with
respect to any required registration or other qualification of securities under
any Federal or state law or regulation of any governmental authority other than
the Securities Act.

                 (f)  Indemnification Payments.  The indemnification and
contribution required by this Section 2.5 shall be made by periodic payments of
the amount thereof during the course of

the investigation or defense, as and when bills are received or expense, loss,
damage or liability is incurred, provided the indemnified party agrees to repay
such payments if it is ultimately determined that the indemnified party was not
entitled to indemnification.

                 2.6.     Adjustments Affecting Registrable Securities.  The
Company will not effect or permit to incur any combination or subdivision of
Registrable Securities which would materially adversely affect the ability of
the holders of Registrable Securities to include such Registrable Securities in
any registration of its securities contemplated by this Section 2 or the
marketability of such Registrable Securities under any such registration.

                 2.7.     Certain Rights of Holders If Named in a Registration
Statement.  If any statement contained in a registration statement under the
Securities Act refers to any holder of Registrable Securities by name or
otherwise as the holder of any securities of the Company and such reference to
such holder by name or otherwise is not required by the Securities Act or any
of the rules and regulations promulgated thereunder, then such holder shall
have the right to require the deletion of the reference to such holder.

                 2.8.     Rule 144.  If the Company shall have filed a
registration statement pursuant to the requirements of Section 12 of the
Exchange Act or a registration statement pursuant to the requirements of the
Securities Act, the Company will file the reports required to be filed by it
under the Securities Act and the Exchange Act and the rules and regulations
adopted by the Commission thereunder (or, if the Company is not required to
file such reports, will, upon the request of any holder, make publicly
available other information) and will take further action as any holder may
reasonably request, all to the extent required from time to time to enable such
holder to sell Registrable Securities without registration under the Securities
Act within the limitation of the exemptions provided by any rule or regulation
now in effect or hereafter adopted by the Commission.  Upon the request of any
holder, the Company will deliver to such Holder a written statement as to
whether it has complied with such requirements.

                 2.9.     Conversion of Exercise of Securities.  The Securities
must be converted into, or exercised for, Common Stock prior to the sale of
such Securities pursuant to a registration under this Agreement.

                 3.       Holdback Agreements.  Each holder of Registrable
Securities agrees not to effect any public sale of equity securities of the
Company, or any securities convertible into or exchangeable or exercisable for
such securities, including a sale to the public pursuant to Rule 144 of the
Commission, during the period commencing fifteen (15) days prior to and ending
ninety (90) days after the effective date of any underwritten registration of
the Company's

securities (except as part of such underwritten registration), if and to the
extent requested by the underwriter or underwriters managing the registered
public offering, unless such underwriter or underwriters otherwise agree.

                 4.       Restrictions on Dispositions.  In connection with the
disposition of the Registrable Securities under a registration statement
pursuant to this Agreement, in order for any holder of Registrable Securities
to dispose of Registrable Securities pursuant to a prospectus that is a part of
such registration statement (other than an underwritten offering), such holder
must give the Company written notice of its intention to sell any of the
Registrable Securities at least two (2), but not more than twenty (20),
business days prior to the date of the proposed sale(s), which notice shall
include the number of shares proposed to be disposed, and the time period
during which the shares may be disposed (the "Sale Period"), and the holder
agrees that, during the Sale Period, it shall not deliver any prospectus that
is a part of such registration statement in connection with any disposition of
the Registrable Securities during any period of time when, but only so long as,
the Company, after receipt of the notice set forth above, notifies such holder
that the Company is in possession of material non- public information that
would be required to be disclosed in the registration statement (or any
amendment, or post-effective amendment thereto); provided that the Company
shall advise such holder in writing as soon as any such delay is no longer
applicable.

                 5.       Limitations on Subsequent Registration Rights.   From
and after the date of this Agreement, the Company shall not, without the prior
consent of the Executive Committee of the Board of Directors of the Company,
enter into any agreement with any holder or prospective holder of any
securities of the Company giving such holder or prospective holder any
registration rights the terms of which are pari passu with or more favorable
than the registration rights granted hereunder.

                 6.       Transfer or Assignment of Registration Rights.  The
rights to cause the Company to register securities granted to a holder of
Registrable Securities by the Company in this Agreement may be transferred or
assigned by such a holder in connection with the transfer of the Registrable
Securities; provided, the Company is given written notice at the time of or
within a reasonable time after said transfer or assignment, stating the name
and address of the transferee or assignee and identifying the Securities with
respect to which such registration rights are being transferred or assigned,
and, provided further, that the transferee or assignee of such rights assumes
in writing the obligations of such holder under this Agreement.

                 7.       Amendment and Waivers.  This Agreement may be amended
with the consent of the Company and the Company may take any action herein
prohibited, or omit to

perform any act herein required to be performed by it, only if the Company
shall have obtained the written consent to such amendment, action or omission
to act, of the holders of not less than a majority of the Registrable
Securities.  Each holder of any Registrable Securities at the time or
thereafter outstanding shall be bound by any consent authorized by this Section
7, whether or not such Registrable Securities shall have been marked to
indicate such consent.

                 8.       Nominees for Beneficial Owners.  In the event that
any Registrable Securities are held by a nominee for the beneficial owner
thereof, the beneficial owner thereof may, at its election in writing delivered
to the Company, be treated as the holder of such Registrable Securities for
purposes of any request or other action by any holder or holders of Registrable
Securities pursuant to this Agreement or any determination of any number or
percentage of shares of Registrable Securities contemplated by this Agreement.
If the beneficial owner of any Registrable Securities so elects, the Company
may require assurances reasonably satisfactory to it of such owner's beneficial
ownership of such Registrable Securities.

                 9.       Notices.  All communications provided for hereunder
shall be sent via overnight courier, shall be deemed to be received two (2)
days after being sent, or, if earlier, the date of actual receipt, and shall be
addressed as follows:

                 (a)      if to the Purchasers, addressed to the Purchasers in
the manner set forth in the Stock and Warrant Purchase Agreement, or at such
other address as any Purchaser shall have furnished to the Company in writing;

                 (b)      if to any other holder of Registrable Securities, at
the address that such holder shall have furnished to the Company in writing,
or, until any such other holder so furnishes to the Company an address, then to
and at the address of the last holder of such Registrable Securities who has
furnished an address to the Company; or

                 (c)      if to the Company, addressed to it in the manner set
forth in the Stock and Warrant Purchase Agreement, or at such other address as
the Company shall have furnished to each holder of Registrable Securities at
the time outstanding.

                 10.      Assignment; Calculation of Percentage Interests in
Registrable Securities.  (a)  This Agreement shall be binding upon and inure to
the benefit of and be enforceable by the parties hereto and, with respect to
the Company, its respective successors and assigns.

                                                              Purchase Agreement


                 (b)      For purposes of this Agreement, all references to a
percentage of the Registrable Securities shall be calculated based upon the
number of shares of Registrable Securities outstanding at the time such
calculation is made.

                 11.      Descriptive Headings.  The descriptive headings of
the several sections and paragraphs of this Agreement are inserted for
reference only and shall not limit or otherwise affect the meaning hereof.

                 12.      GOVERNING LAW.  THIS AGREEMENT SHALL BE CONSTRUED AND
ENFORCED IN ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED
BY, THE LAWS OF THE STATE OF ILLINOIS.

                 13.      Severability.  If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of
law, or public policy, all other provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any manner
materially adverse to any party.

                 14.      Counterparts.  This Agreement may be executed in any
number of counterparts, each of which shall be deemed an original, but all such
counterparts shall together constitute one and the same instrument.
