                                  ______, 1996

Dear Fellow Shareholders:

     You are cordially invited to attend the Special Meeting of Shareholders
(the "Papnet Special Meeting") of Papnet of Ohio, Inc. ("Papnet"), which will be
held on _________, September __, 1996, at _____ _., local time.  The Papnet
Special Meeting will be held at______________________________________________.

     At the Papnet Special Meeting, shareholders of Papnet will be asked to
consider and vote on  the Agreement and Plan of Merger, dated as of July 5, 1996
(the "Merger Agreement"), among Papnet  and Cytology Indiana, Inc., Indiana
Cytology Review Company, ER Group, Inc., CCWP Partners, Inc. and Carolina
Cytology, Inc. (individually a "Predecessor Company" and collectively
"Predecessor Companies"), pursuant to which the Predecessor Companies would be
merged with and into Papnet (the "Merger").  In the Merger, the shareholders of
the Predecessor Companies will receive whole shares of Papnet common stock in
exchange for each share of  Predecessor Company common stock held by them.  The
actual number of shares of Papnet stock to be exchanged for each share of
Predecessor Company  stock will be determined pursuant to Schedule 2.05(a) of
the Merger Agreement.

     Each of the Predecessor Companies, except CCWP Partners, Inc.,  was
organized to acquire and exercise the right to market the PAPNET-Registered
Trademark- SYSTEM and PAPNET-Registered Trademark- SERVICE within their
respective licensed territories.  However, until November 8, 1995, when the
United States Food and Drug Administration finally approved the marketing of the
PAPNET-Registered Trademark- technology, the technology could be used in the
United States only for investigational purposes in connection with the FDA
approval process.  Consequently, the Predecessor Companies had only minor
business activities prior to November, 1995, and had no employees.

     THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AS BEING IN THE
BEST INTEREST OF PAPNET SHAREHOLDERS AND RECOMMENDS THAT YOU VOTE IN FAVOR OF
THE APPROVAL OF THE AGREEMENT AND PLAN OF MERGER.

     Additional information regarding the Merger and the parties thereto is set
forth in the attached Proxy Statement, which also serves as the Prospectus
regarding the common stock of Papnet to be issued in connection with the Merger.
Please read these materials and carefully consider the information contained in
them.

     The affirmative vote of the holders of at least two-thirds of the
outstanding shares of Papnet Common Stock is required to approve the Merger and
the Amended and Restated Articles of Incorporation and Amended and Restated
Regulations pursuant thereto.  An affirmative vote for the Merger Agreement will
act as an affirmative vote for the Amended and Restated Articles of
Incorporation and Amended and Restated Regulations. Accordingly, your vote is
important no matter how large or how small your holdings may be.  Whether or not
you plan to attend the Papnet Special Meeting, you are urged to complete, sign,
and promptly return the enclosed proxy card to assure that your shares will be
voted at the Papnet Special Meeting.  If you attend the Papnet Special Meeting,
you may vote in person if you wish and your proxy will not be used.

                                             Very truly yours,



                                             David J. Richards

                                DAVID J. RICHARDS
                           CHAIRMAN OF ADVISORY BOARD


Dear Predecessor Company Shareholders:

     On July__, 1996, Papnet of Ohio, Inc. ("Papnet") entered into an Agreement
and Plan of Merger (the "Merger Agreement") with  Cytology Indiana, Inc.
("CIN"), Indiana Cytology Review Company ("INC"), ER Group, Inc. ("ERG"), CCWP
Partners, Inc. ("CCWP"), and Carolina Cytology, Inc. ("CCI") (individually
"Predecessor Company" collectively "Predecessor Companies"), pursuant to which
the Predecessor Companies will merge (the "Merger") with and into Papnet.  As a
result of the Merger, all shareholders of a Predecessor Company will be entitled
to receive shares of Papnet common stock in exchange for the shares of
Predecessor Company stock held by them (the "Merger Consideration").  Under the
terms of the Merger Agreement, I have been selected as Chairman of the Advisory
Board, a board consisting of shareholders and officers of the Predecessor
Companies.  It is in this capacity that I write you this letter.

     The number of shares of Papnet common stock that will comprise the Merger
Consideration is calculated based on the conversion ratio contained in Schedule
2.05 of the Merger Agreement.  Each share of Predecessor Company stock that is
held in treasury shall be extinguished.

     THE BOARDS OF DIRECTORS OF PAPNET AND THE PREDECESSOR COMPANIES HAVE
UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND BELIEVE THAT THE MERGER IS IN THE
BEST INTERESTS OF ALL PREDECESSOR COMPANIES SHAREHOLDERS.  THE BOARD OF
DIRECTORS OF EACH PREDECESSOR COMPANY  BELIEVES THAT THIS STRATEGIC COMBINATION
WITH PAPNET WILL CREATE AN EFFICIENT AND EFFECTIVE ENTITY.

     Approval of the Merger and the Merger Agreement and the transactions
contemplated thereby requires the affirmative vote of the holders of common
stock of each ERG, CCWP, and CCI entitling them to exercise a majority of the
voting power of the respective corporations. Approval of the Merger and the
Merger Agreement and the transactions contemplated thereby requires the
affirmative vote of the holders of shares entitling them to exercise at least
two-thirds of the voting power of CIN and INC.  In accordance with the General
Corporation Law of the State of Ohio, the Merger and the Merger Agreement may be
approved without a meeting of shareholders of the Predecessor Companies with the
affirmative vote, in a writing or writings, signed by all the shareholders who
would be entitled to notice of a meeting of the shareholders held for such
purpose.   It is expected that all the shareholders of each Predecessor Company
will unanimously consent in writing to the Merger and therefore, at this time no
special meetings for the shareholders of the Predecessor Companies is planned.

     The accompanying Prospectus explains in detail the terms of the Merger and
the Papnet common stock to be issued in the Merger.  It also contains pro forma
financial information and other information concerning Papnet, the Predecessor
Companies and the Merger.  Although you are not being asked for a proxy or
written consent, and are requested not to send a proxy or written consent,
please read the Prospectus carefully.

     If unanimous consent of the shareholders of any Predecessor Company is not
obtained, then a special meeting of shareholders of that Predecessor Company
will be called.  Shareholders who do not consent to the Merger Agreement are
entitled to dissenter's rights as described in the Prospectus.  TO EXERCISE SUCH
DISSENTER'S RIGHTS, SHAREHOLDERS MUST TAKE CERTAIN ACTIONS WITHIN THE TIME
LIMITS PRESCRIBED BY OHIO LAW.  The Prospectus describes the actions
shareholders must take and other relevant considerations to the exercise of such
rights.

                                                  Very truly yours,


                                                  David J. Richards

     The Company's shareholders must vote to approve the Merger and the

with respect to  their shares and receive the "fair cash value" of such shares.

     In addition, Section 1701.85 provides the holders of record of shares of
the Predecessor Companies' common stock, who properly exercise and perfect
dissenting shareholder rights with respect to the Merger, the right to obtain a
cash payment for the "fair cash value" of their shares (excluding any element of
value arising from the accomplishment or expectation of the Merger).  In order
to exercise such rights, holders must comply with the procedural requirements of
the General Corporation Law of Ohio, a description of which is provided under
"THE MERGER - Dissenters' Rights" and the full text of which is attached to this
Prospectus as Appendix B.  Failure to take any of the steps required under the
General Corporation Law of Ohio on a timely basis may result in the loss of
dissenters' rights.  See "THE MERGER - Dissenters' Rights."

                                     SUMMARY

     THE FOLLOWING IS A BRIEF SUMMARY OF CERTAIN INFORMATION WITH RESPECT TO THE
MERGER.  THIS SUMMARY IS NOT INTENDED TO BE COMPLETE AND IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO, AND SHOULD BE READ IN CONJUNCTION WITH, THE DETAILED
INFORMATION AND FINANCIAL STATEMENTS CONTAINED HEREIN AND IN THE EXHIBITS
HERETO.

THE COMPANY

     The Company is an Ohio corporation formed on October 25, 1989 for the
purpose of acquiring from Neuromedical Systems, Inc. ("NSI") the exclusive
rights to market the PAPNET-Registered Trademark- System and the
PAPNET-Registered Trademark- Service in the State of Ohio.  The Company later
assigned its rights to Papnet Limited Partnership, an Ohio limited partnership
("PLP").   In January 1993, the Company acquired all of the issued and
outstanding units of limited partnership interest in both PLP and Papnet Midwest
Limited Partnership, an Ohio limited partnership ("PMLP").  PMLP owned the
rights to market the PAPNET-Registered Trademark- System and PAPNET-Registered
Trademark- Service in Kentucky and the Standard Metropolitan Area of Chicago,
Illinois.  As a result of these acquisitions the Company has the marketing
rights to the PAPNET-Registered Trademark- System and the PAPNET-Registered
Trademark- Service in Ohio, Kentucky and the Standard Metropolitan Area of
Chicago.

     The PAPNET-Registered Trademark- System is a semi-automated cancer
detection system for the review of cell, tissue or body fluid specimens,
including but not limited to, cervical cytology specimens ("Slides").  The
PAPNET-Registered Trademark- Service permits laboratories to submit Slides to
one of NSI's central facilities for image processing employing NSI's patented
neural network technology.  NSI returns the Slides and digital tape containing
processed images for evaluation by NSI-trained cytotechnologists.

     The Company's offices are located at 6059 Memorial Drive, Dublin, Ohio
43017 and its telephone number is (614) 793-9356.

THE PREDECESSOR COMPANIES

GENERAL

     Each of the Predecessor Companies, other than CCWP, was organized to
acquire and exercise the right to market the PAPNET-Registered Trademark- System
and PAPNET-Registered Trademark- Service within its licensed territory.
However, until November 8, 1995, when the United States Food and Drug
Administration ("FDA") finally approved the marketing of the PAPNET-Registered
Trademark- technology, the technology could be used in the United States only
for investigational purposes in connection with the FDA approval process.   CCWP
is an affiliate of CCI, and was organized for the purpose of holding certain 
warrants for the purchase of NSI common stock.  Consequently,  the Predecessor 
Companies had only minor levels of  business activities prior to November 1995.

THE MERGER; GENERAL TERMS

     At the Effective Time of the Merger, the Predecessor Companies will be

Predecessor Companies' common stock, including shares of the Predecessor
Companies issuable upon the exercise of outstanding warrants and options, shall
be converted into the right to receive fully paid and nonassessable Company
Shares (the "Merger Consideration").  Shares of outstanding common stock of the

Company Shares based on a ratio of one Predecessor Company share for the
following number of shares of the Company:  CIN (1,121.6652); INC (4,491.7064);
ERG (3,237.2643); CCWP (37.3971); and CCI (1,487.6186).  See "THE MERGER - The
Merger Agreement (Merger Consideration Generally)."

     VOTE REQUIRED.  Approval of the Merger and the Merger Agreement and the
transactions contemplated thereby requires the affirmative vote of the holders
of common shares of each of ERG, CCWP, and CCI entitling them to exercise a
majority of the voting power of the respective corporations and the affirmative
vote of holders of shares entitling them to exercise at least two-thirds of the
voting power of the Company, CIN, and INC.  In addition to the approval of the
Merger, the adoption of amendments to the Company's Articles of Incorporation
must be approved by the holders of at least two thirds of the outstanding stock
of the Company entitled to vote thereon.  In the event that the shareholders of
the Company and each of the Predecessor Companies approve and adopt the Merger
and the Merger Agreement as required by their respective Articles of
Incorporation and the General Corporation Law of Ohio, and upon satisfaction or
waiver of all other conditions to the Merger, the Merger will be consummated
without any further vote of the shareholders of the Company or the Predecessor
Companies.  See "THE MERGER - Required Vote."

     CONDITIONS TO THE MERGER; TERMINATION.  The respective obligations of the
Company and the Predecessor Companies to consummate the Merger are subject to
certain conditions, including among others the adoption of the Merger and the
Merger Agreement by the holders of the requisite number of shares of the Company
and Predecessor Companies' common stock; the compliance by


                                       -7-

each of the parties to the Merger Agreement with its material obligations
thereunder and the truth of the representations and warranties made by each of
the parties on the date of the Merger Agreement and at the Effective Time; the
Registration Statement shall have become effective under the Securities Act;
the Company shall have received all state securities or "Blue Sky" permits and
other authorizations necessary to issue the Company Shares pursuant to the
Merger and the Merger Agreement; the Company Shares shall have been admitted for
quotation on the National Market of the National Association of Securities
Dealers, Inc. Automated Quotation system ("NASDAQ NMS") upon official notice of
issuance;  at the time of the consummation of the transactions contemplated by
the Merger Agreement (the "Closing"), the shareholders of the Company or any
Predecessor Company entitled to assert dissenter's rights shall own in the
aggregate less than 10% of the outstanding shares of the Company or the
Predecessor Company; and the Company and the Predecessor Companies having
received an opinion of Porter, Wright, Morris & Arthur, counsel to the Company,
to the effect that, among other things, the Merger will be treated for federal
income tax purposes as a reorganization within the meaning of Section 368(a) of
the Internal Revenue Code of 1986, as amended (the "Code") and each Predecessor
Company will be a party to that reorganization within the meaning of Section
368(b) of the Code and that the holding period for the Company Shares received
in exchange for the Predecessor Company shares will include the period for which
the Predecessor Company shares were held, provided that the Predecessor Company
shares were held as a capital asset.  See "THE MERGER - The Merger Agreement
(Conditions to Consummation of the Merger)."

     The Merger Agreement may be terminated by mutual consent of all of the
parties; by any of the parties if the Merger shall not have been consummated
before September 30, 1996 (unless the failure to consummate the Merger by such
date shall be due to the action or failure to act of the party seeking to
terminate the Merger Agreement); by any party if any permanent injunction or
other order of a court or other competent authority shall have become final and
non-appealable; or by any party if any required approval of the shareholders of
such party or any other party shall not have been obtained.  The Merger
Agreement may also be terminated by a vote of the majority of a seven member
interim advisory board (the "Advisory Board") appointed by the parties.

     In the event that the Merger Agreement is terminated, the Merger Agreement
shall be void and have no effect, without any liability on the part of any party
or its affiliates, directors, officers, or shareholders.  Notwithstanding the
foregoing, the parties to the Merger Agreement will continue to be bound by the
provisions of the Merger Agreement that relate to: (i) their respective
obligations as to confidentiality and the payment of any broker's or finder's
fees; (ii) a party's obligation to pay liquidated damages in the amount of
$500,000 to the other parties if the termination arises out of that party's
failure to obtain the required approval of the Merger and the Merger Agreement
or that party's breach of the Merger Agreement; and (iii) a party's obligation
to pay its share of all costs and expenses incurred by the parties in connection
with the Merger and the transactions contemplated by the Merger Agreement.  A
party's share of any liquidated damages paid as a result of a termination of the
Merger  or its share of costs and expenses required to be paid by it under the
Merger Agreement shall be in proportion to the number of Company Shares that are
or would have been owned by the party's shareholders immediately after the
Effective Time.  See "THE MERGER - The Merger Agreement (Termination)."

     ACCOUNTING TREATMENT.   The merger will be effected by an exchange of the
Company's common stock for the outstanding common shares of the Predecessor
Companies.  The merger of the Company and the Predecessor Companies will be
accounted for at historical cost. For accounting purposes, the Company will be
the predecessor of the merged entity and its historical financial statements
will be those of the new entity NetMed, Inc.  The results of operations of the
Predecessor Companies will be combined with those of the Company commencing at
the date of merger. See "THE MERGER - Anticipated Accounting Treatment."

     FEDERAL INCOME TAX CONSEQUENCES.   The following discussion is a general
summary of the principal federal income tax consequences of the Merger to
individual United States holders of the Predecessor Companies  shares who hold
their shares as capital assets.  The discussion is based on laws, regulations,
rulings and decisions currently in effect.  It is for general information only,
and is not intended to be tax advice to any particular shareholder of the
Company or a Predecessor Company.  The discussion does not take into account
rules that are applicable to shareholders of the Predecessor Companies that are
subject to special treatment under the Code, including without limitation,
insurance companies, dealers in securities, financial institutions, tax-exempt
investors, foreign investors, shareholders who do not hold their stock as a
capital asset and shareholders who acquired shares pursuant to the exercise of
an employee stock option, employee stock purchase plan or otherwise as
compensation.  The discussion also does not address state, local or foreign tax
consequences of the Merger.  No rulings have been or will be requested from the
Internal Revenue Service with respect to the tax consequences of the Merger.

     Assuming the Merger is consummated in the manner set forth in the Merger
Agreement and qualifies as a reorganization under Section 368 of the Code, the
principal federal income tax consequences of the Merger under present federal
income tax law will be as described below.

     (a)  No gain or loss will be recognized by the Company or the Predecessor
          Companies as a result of the Merger;

     (b)  No gain or loss will be recognized by the holders of Predecessor
          Company shares upon the exchange of their shares of Predecessor
          Company shares for Company Shares pursuant to the Merger (except for
          any gain or loss attributable to cash received by a holder of
          Predecessor Company stock in payment of appraisal or dissenters'
          rights of appraisal or for fractional share interests to which they
          may be entitled );

     (c)  The federal income tax basis of the Company Shares received by the
          shareholders of the Predecessor Companies (including fractional share
          interests to which they may be entitled) for their Predecessor Company
          shares will be the same as the federal income tax basis of the
          Predecessor Company shares surrendered in exchange therefor, increased
          by any gain recognized; and

     (d)  The holding period for the Company Shares received by shareholders of
          the Predecessor Companies in exchange for their Predecessor Company
          shares will include the period for which the Predecessor Company 
          shares exchanged therefor were held,


                                       -9-
<PAGE>

          provided that the exchanged Predecessor Company shares were held as a
          capital asset by such shareholder on the date of the exchange.

     It is a condition to the closing that the Company and the Predecessor
Companies shall have received an opinion of Porter, Wright, Morris & Arthur
which will be based upon certain certificates, representations and assumptions,
substantially to the effect that, for federal income tax purposes the Merger
will constitute a reorganization within the meaning of section 368(a) of the
Code and will result in the tax consequences described above.

     No opinion will be expressed with respect to any other tax consequences of
the exchange, including, without limitation, the tax consequences with respect
to any shares of Predecessor Company stock that were acquired in contemplation
of the Merger, were held by shareholders subject to special treatment under the
Code, were not held as capital assets or were acquired by the holder thereof
pursuant to any employee stock option, employee stock purchase plan or otherwise
as compensation or pursuant to the exercise of any warrants to purchase shares
of Predecessor Company stock.  Further, no opinion will be expressed concerning
the effect of state, local and foreign tax laws.  An opinion of counsel is not
binding upon the IRS, and there can be no assurance that the IRS will not take a
position contrary to the positions reflected in such opinion or that such
opinion will be upheld by the courts if challenged by the IRS.

     THE SPECIFIC TAX TREATMENT OF EACH SHAREHOLDER WILL DEPEND ON THEIR
PARTICULAR FACTS AND CIRCUMSTANCES.  EACH HOLDER OF COMPANY SHARES AND
PREDECESSOR COMPANY SHARES IS ADVISED TO CONSULT WITH SUCH STOCKHOLDER'S OWN TAX
ADVISER CONCERNING THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER, AS WELL AS
THE APPLICABLE STATE, LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES.  See "THE MERGER
- - Certain Federal Income Tax Consequences."


REASONS FOR THE MERGER; RECOMMENDATION OF  THE COMPANY'S AND THE  PREDECESSOR
COMPANIES' BOARDS OF DIRECTORS

     In evaluating the proposed Merger, the Boards of Directors of the Company
and the Predecessor Companies, with the assistance of outside counsel and other
advisors, considered a variety of factors, including the following: (i) the
efficiencies created through the combined entity; (ii) the relative market
positions of each of the Company and the Predecessor Companies and the increased
market penetration of the combined entity; (iii) the ability of management of
the combined entity to realize the full potential of the combined entity; (iv)
the opportunity that the combination would afford the Predecessor Companies'
shareholders to acquire an equity participation in a larger  enterprise with
significantly larger equity value than any one of the Predecessor Companies; (v)
the terms of the Merger Agreement; and (vi) the potential for greater liquidity
for the shareholders of the Company and Predecessor Companies.

     The directors of the Company and the Predecessor Companies have unanimously
determined that the Merger Agreement and the Merger are advisable and fair and
in the best interests of the Company and the Predecessor Companies and recommend
that their respective shareholders approve the Merger Agreement and the Merger.

Reasons for the Merger" and "- Recommendation of the Predecessor Companies'
Boards of Directors."

RESTRICTIONS ON TRANSFER OF THE COMPANY SHARES

     Certain persons who may be deemed "affiliates" of the Company or any of the
Predecessor Companies for purposes of Rule 145 under the Securities Act ("Rule
145") will not be permitted to transfer their Company Shares issued in the
Merger except (i) pursuant to an effective registration statement; (ii) in
compliance with Rule 145; or (iii) pursuant to an exemption from the
registration requirements of the Securities Act.  This Prospectus does not cover
resales of Company Shares by affiliates of the Company or the Predecessor
Companies.   In addition certain affiliates of the Company and the Predecessor
Companies have agreed not to sell their Company Shares for a specified period of
time.  See "THE MERGER - Resales by Affiliates."

     Under the terms of the Merger Agreement, the Predecessor Company
shareholders have, with respect to the Company shares that each receives in the
Merger, and David J. Richards, John P. Kennedy and Carl A. Genberg (the "Key
Company Shareholders") have, with respect to their shares of the Company, agreed
to certain additional restrictions on the transfer of their respective shares of
the Company.  Except with respect to certain privately negotiated sales, the
Predecessor Company shareholders will be prohibited from selling more than an
aggregate of 625,000 Company Shares during the one year period commencing on the
closing date of the Merger.  The number of Company Shares that each Predecessor
Company shareholder will be entitled to sell is equal to the product of (A) the
ratio of Company Shares received with respect to the conversion of the
shareholder's shares in a Predecessor Company to the number of Company Shares so
received by all shareholders of such Predecessor Company, times (B) the number
of shares allocated to such Predecessor Company in the Merger Agreement for the
relevant time period.  Except with respect to certain privately negotiated sales
and certain transactions involving the pledge of the shares held by the Key
Company Shareholders, the Key Company Shareholders have agreed not to sell the
Company Shares they own immediately after the Merger for a period of one year
commencing on the closing of the Merger.  See "Merger Agreement - Appendix A."

CERTAIN RELATED TRANSACTIONS

     Each of the other Predecessor Companies and the Company entered into a Loan
Agreement, dated July 5, 1996 (the "Loan Agreement"), whereby the Company has
agreed to advance to the other Predecessor Companies the expenses incurred by
each in connection with the Merger.   In addition, the Company will advance
funds necessary to pay reasonable expenses of ordinary business operations for
the Predecessor Companies pending consummation of the Merger (collectively, the
"Advances").   Advances made to the Predecessor Companies in connection with the
merger that was abandoned in June 1996 (the "Initial Advances") will be added to
the Advances.  The Initial Advances and the Advances will be evidenced by a
promissory note bearing interest at an annual rate of 7%, payable 180 days after
the earlier of the consummation of the Merger or the termination of the Merger
Agreement.  Promissory notes delivered by the Predecessor Companies will be
secured by their shares of NSI common stock.


                                      -11-
<PAGE>

     The Loan Agreement has been modified by a side-letter agreement among the
Company, ERG, CCI and CCWP, dated July 16, 1996, which provides, among other
things, terms relating to notice and cure periods for any defaults and credits
for certain expenses that are paid directly by these Predecessor Companies.

     The Company entered into a loan agreement, dated March 14, 1996 with
Cytology West, Inc. ("CWI") and Papnet Utah, Inc. ("PUI").  CWI is licensed to 
sell the PAPNET-Registered Trademark- System and the PAPNET-Registered 
Trademark- Service in Arizona, Nevada and San Diego County California.  PUI is 
licensed to sell PAPNET-Registered Trademark- System and the PAPNET-Registered 
Trademark- Service in Utah.  Carl Genberg, President of CWI, owns 383,616 
shares of the Company's common stock and may be deemed to be an affiliate of 
the Company.  CWI and PUI were originally to have been a parties to a merger 
with the Company and the Predecessor Companies, but that transaction was 
abandoned by the parties.  The loan agreement provides for advances to CWI of 
up to $585,000 to cover certain operating expenses, expenses associated with 
the abandoned merger, and the acquisition of new technology.  No specific 
amount was established for advances to PUI.  The advances will bear interest 
at the rate of 7% per annum.  As of June 15, 1996, the Company had advanced 
approximately $146,320 to CWI and $14,315 to PUI under the terms of the loan 
agreement, and no further advances will be made.

     The Company, the Predecessor Companies and certain individual shareholders
of these companies entered into a Voting Agreement, dated July 5, 1996, pursuant
to which the individual shareholders appointed John P. Kennedy and Cecil J.
Petitti as their proxies and attorneys-in-fact for the purpose of voting their
shares in the Company or Predecessor Company, as the case may be, in favor of
the Merger, the Merger Agreement and the transactions contemplated thereby.

     Pending completion of the Merger, the business operations of CIN, INC, ERG,
and CCI are being managed by the Company.

DISSENTER'S RIGHTS

     Under Ohio General Corporation Law, holders of record of shares of the
Company and the Predecessor Companies who properly exercise and perfect
dissenter's rights with respect to the Merger will have the right to receive the
"fair cash value" of their shares (excluding any appreciation or depreciation in
market value resulting from the Merger).  In order to exercise such rights,
holders must comply with the procedural requirements of Section 1701.85 of the
Ohio Revised Code, a description of which is provided under "THE MERGER -
Dissenter's Rights" and the full text of which is attached to this Prospectus as
Appendix B.   Failure to take any of the steps required under Section 1701.85 on
a timely basis may result in the loss of dissenter's rights.  See "THE MERGER -
Dissenter's Rights."

COMPARATIVE PER SHARE INFORMATION

     The Predecessor Companies had only minor levels of  business activities
prior to November 1995.  In addition, there is no public market for the any
Predecessor Company's common stock.  Accordingly, comparative share information
would not be meaningful.

DIVIDEND HISTORY

     The Company has paid no cash dividends since its formation.  The Company
presently anticipates that all of its future earnings will be retained for the
development of its business and does not anticipate paying cash dividends on the
Company common stock in the foreseeable future.  The payment of any future
dividends will be at the discretion of the Company's Board of Directors and will
be based on the Company's future earnings, financial condition, capital
requirements and other relevant factors.

                                  RISK FACTORS

     IN ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS, SHAREHOLDERS OF
THE COMPANY AND THE PREDECESSOR COMPANIES SHOULD CAREFULLY CONSIDER THE
FOLLOWING FACTORS IN EVALUATING THE COMPANY AND ITS BUSINESS BEFORE MAKING A
DECISION REGARDING THEIR VOTE ON THE MERGER.

     LIMITED OPERATING HISTORY.  The Company was formed on October 25, 1989.
Because the Company is in the early stage of its operations it is subject to all
the risks incident to the creation and development of a new business, including
the absence of earnings and minimal net worth.  The Company has to date had no
appreciable income from operations, and as of March 31, 1996 has an accumulated
deficit of $287,344.  See INDEX TO FINANCIAL STATEMENTS.


                                      -13-
<PAGE>

     LICENSE AGREEMENT.  The Company's rights to market the PAPNET-Registered
Trademark- System and PAPNET-Registered Trademark- Service and the revenues
generated by these activities are governed by the terms of a License Agreement
with NSI (the "License Agreement").  The License Agreement imposes significant
territorial and other restrictions on the Company's marketing rights, and places
certain limitations on the amounts of royalty revenues which the Company can
generate through the marketing of the PAPNET-Registered Trademark- System and
PAPNET-Registered Trademark- Service.  See "THE COMPANY -  The License."

     RELIANCE ON NSI.  The business of the Company is dependent upon a number of
factors, many of which are controlled by NSI.  These factors include maintaining
the PAPNET-Registered Trademark- System's compliance with FDA and other
regulatory requirements, maintenance of the technological advantages of the
PAPNET-Registered Trademark- System, maintenance of product liability insurance,
the ability to manufacture and deliver the equipment required to operate the
PAPNET-Registered Trademark- System, and the ability to build and operate the
Scanning Station portion of the PAPNET-Registered Trademark- System.  Further,
NSI is in a stage of development that may require additional funding for its
internal operations.  In the event that NSI should fail to perform in any of
these areas, or in any others which could affect its licensees, such failure
could have an adverse effect on the Company and its business.  The Company is
dependent and relies upon NSI for product information, support and marketing and
other pertinent information.

     Further, NSI does not manufacture all of the equipment used in the
PAPNET-Registered Trademark-  System, and is therefore dependent upon others to
do so.  The failure of NSI's suppliers to perform could have an adverse effect
on the Company's business.

     NEED FOR MARKET ACCEPTANCE OF THE PAPNET-Registered Trademark- SYSTEM.  The
Company's future performance will depend to a substantial degree upon market
acceptance of the PAPNET-Registered Trademark- System.  The extent of, and rate
at which, market acceptance and penetration are achieved by the
PAPNET-Registered Trademark- System are functions of many variables including,
but not limited to, price, effectiveness, acceptance by patients, physicians and
laboratories (including the ability of laboratories to hire additional
cytotechnologists), manufacturing, slide processing and training capacity,
reimbursement practice and marketing and sales efforts.  There can be no
assurance that the PAPNET-Registered Trademark- System will achieve or maintain
acceptance in its target markets. See "THE COMPANY - The Market."

     RELIANCE ON A SINGLE PRODUCT.  While the Company intends to develop or
acquire other technologies, it has concentrated its efforts primarily on the
marketing of the PAPNET-Registered Trademark- System and will be dependent upon
the successful development of that product to generate revenues.   Accordingly,
for the foreseeable future, the Company's success will be dependent upon the
marketing of the PAPNET-Registered Trademark- System.

     DEPENDENCE ON PATENTS AND PROPRIETARY TECHNOLOGY.  The technology
underlying the PAPNET-Registered Trademark- System is protected by broad patent
protection granted to NSI with respect to the use of neural networks in
automated and semi-automated cytology.  There can be no assurance that the NSI
patents will afford protection from material infringement or that such patents
will not be challenged.  NSI and the Company will also rely on trade secrets and
proprietary know-how, which they will seek to protect, in part, through
confidentiality agreements with employees, consultants and other parties.  There
can be no assurance that these agreements will not be breached, that there will
be adequate remedies for any breach or that trade secrets of NSI or the Company
will not otherwise become known to, or independently developed by, competitors.


                                      -14-

     The medical device industry has been characterized by extensive litigation
regarding patents and other intellectual property rights.  Although patent and
intellectual property disputes in the medical device area have often been
settled through licensing or similar arrangements, costs associated with such
arrangements may be substantial and there can be no assurance that necessary
licenses would be available to NSI or the Company on satisfactory terms or at
all.  Adverse determinations could limit the value of NSI's or the Company's
issued patents or result in invalidation of those patents, subject NSI  or the
Company to significant liabilities to third parties, require NSI or the Company
to seek licenses from third parties or prevent NSI or the Company from
manufacturing and selling its products, any of which could have a material
adverse effect on the Company's business, financial condition and results of
operations.

     PRODUCT LIABILITY.  The business of the Company could expose it to the
risks inherent in the production and distribution of medical diagnostic
equipment.  Although NSI has attempted to reduce the exposure to product
liability risk by disclosing the demonstrated range of accuracy of the
PAPNET-Registered Trademark- System, there can be no assurance that the Company
will not be exposed to liability resulting from the failure or inaccuracy of the
PAPNET-Registered Trademark- System.  Neither the Company nor any  Predecessor
Company carries product liability insurance.  However, NSI is required, under
the terms of the License Agreement, to name the Company and each Predecessor
Company as additional insureds on its product liability policy.

     TECHNOLOGY RISKS.  NSI, and consequently the Company, are dependent upon
the technological advantages of the PAPNET-Registered Trademark- System and its
patent protection.  There can be no assurance that NSI will be able to maintain
such advantages, and the failure to do so could have adverse consequences on the
business of the Company.

     GOVERNMENT REGULATION.  NSI's services, products and manufacturing
activities are subject to extensive and rigorous government regulation,
including the provisions of the Medical Device Amendment to the Federal Food,
Drug and Cosmetic Act.  Commercial distribution in certain foreign countries is
also subject to government regulations.  The process of obtaining required
regulatory approvals can be lengthy, expensive and uncertain.  Moreover,
regulatory approvals, if granted, may include significant limitations on the
indicated uses for which a product may be marketed.  The FDA actively enforces
regulations prohibiting marketing without compliance with the premarket approval
provisions of products and conducts periodic inspections to determine compliance
with Good Manufacturing Practice regulations.

     The FDA recently warned the Company that certain promotional materials
relating to the PAPNET-Registered Trademark- System appearing on the Company's
World Wide Web site failed to comply with certain FDA premarket approval
regulations.  The FDA cited specific claims made in these materials and advised
the Company that it should review these and other promotional materials to 
ensure compliance with the regulations.  While the Company believes that the 
materials comply in all respects with applicable regulations, it has suspended 
access to these materials on its Web site pending FDA's evaluation of its 
detailed response to the warning letter.

     Failure to comply with applicable regulatory requirements can result in,
among other things, fines, suspensions of approvals, seizures or recalls of
products, operating restrictions and criminal prosecutions.  Furthermore,
changes in existing regulations or adoption of new regulations could


                                      -15-
<PAGE>

prevent NSI from obtaining, or affect the timing of, future regulatory
approvals.  The effect of governmental regulation may be to delay for a
considerable period of time or to prevent the marketing and/or full
commercialization of future  products or services that NSI or the Company may
develop and/or impose costly requirements on NSI or the Company.  There can be
no assurance that NSI or the Company will be able to obtain regulatory approvals
of any products on a timely basis or at all.  Delays in receipt of or failure to
receive such approvals or loss of previously received approvals would adversely
affect the marketing of NSI's and the Company's proposed products.  There can
also be no assurance that additional regulations will not be adopted or current
regulations amended in such a manner as will materially adversely effect NSI or
the Company.

     RELIANCE ON MANAGEMENT.  The success of the Company's operations is highly
dependent upon David J. Richards who has devoted much effort in marketing the
PAPNET-Registered Trademark- System.  The loss of Mr. Richards as an employee
could have an adverse effect on the business of the Company.  The Company has no
employment agreement with Mr. Richards and does not own any insurance policies 
on his life.

     COMPETITION.  The Company is aware of several companies that either have
developed or are developing Pap smear classification systems that are
competitive with the PAPNET-Registered Trademark- System.  Commercial
availability of such products could have a material adverse effect on the
Company's business, financial condition and results of operations.  NSI's
competitors may have substantially greater financial, manufacturing, marketing
and technical resources than NSI and represent significant potential long-term
competition for NSI.  NSI's competitors may succeed in developing products that
are more effective or less costly than any that may be developed by NSI.  These
competitors may also prove to be more successful than NSI in production and
marketing.  New developments are expected to continue at a rapid pace in both
industry and academia.  There can be no assurance that research and development
by others will not render NSI's current and contemplated products obsolete.
Competition may increase further as a result of advances that may be made in the
commercial applicability of technologies and greater availability of capital for
investment in these fields.  Since the Company was organized, competitors have
made strides in developing automated or semi-automated system that could
successfully compete with the PAPNET-Registered Trademark- System.  See "THE
COMPANY - Competition."

     LACK OF PROSPECTIVE DIVIDENDS.  The Company does not contemplate the
payment of dividends on the Company Shares for the foreseeable future.  The
Company has accumulated substantial losses since its inception and there can be
no assurance that the Company's operations will result in sufficient revenues to
enable the Company to operate at profitable levels or to generate positive cash
flow.  Any earnings generated from the operations of the Company will be used to
finance the business and growth of the Company.  See "DESCRIPTION OF SECURITIES
- - Dividends."

     PUBLIC MARKET.  To date, the Company's common stock has traded on a limited
over the counter market.  Although the Company expects that a public market will
develop for its common stock upon consummation of the Merger, there can be no
assurance of that market.  Also, there can be no assurance that, if a market
develops, that it will be an active, liquid or continuous trading market.  The
stock market has experienced extreme price and volume fluctuations and
volatility that has particularly affected the market prices of many technology,
emerging growth and developmental


                                      -16-
<PAGE>

stage companies.  Such fluctuations and volatility have often been unrelated or
disproportionate to the operating performance of such companies.  Factors such
as announcements of the introduction of new or enhanced services or related
products by the Company or its competitors may have a significant impact on the
market price of the Company's common stock.

     CONTROL BY PRINCIPAL SHAREHOLDERS.  Upon completion of the Merger, the
directors, executive officers and principal shareholders of the Company and
their affiliates will collectively own approximately 31% of the outstanding
Company common stock.  As a result, these shareholders will be able to exercise
significant influence over matters requiring stockholder approval, including the
election of directors and approval of significant corporate transactions.  Such
concentration of ownership may have the effect of delaying or preventing a
change in control of the Company.  See "The Company - Principal Shareholders."

     SHARES ELIGIBLE FOR FUTURE SALE; POSSIBLE ADVERSE EFFECT ON MARKET PRICE.
Upon completion of the Merger, the Company will have 10,922,969 shares of common
stock outstanding.  Of these shares, 7,734,437 shares will be held by
nonaffiliates of the Company or the Predecessor Companies and will be, subject
only to the Lock-up provisions of the Merger Agreement, freely tradeable without
restriction or further registration under the Securities Act.  The remaining
3,519,552 shares are or will be held by affiliates of the Company or the
Predecessor Companies, who will be entitled to resell them, subject to the Lock-
up provisions of the Merger Agreement, only pursuant to a registration statement
under the Securities Act or an applicable exemption from registration thereunder
such as an exemption provided by Rule 144 under the Securities Act, or, in the
case of shares acquired in connection with the Merger by affiliates of the
Predecessor Companies, in compliance with the provisions of Rule 145
under the Securities Act.

     Sales of substantial amounts of the Company common stock in the public
market or the prospect of such sales after the Merger could adversely affect the
market price of the Company common stock.

     ANTI-TAKEOVER PROVISIONS; CERTAIN PROVISIONS OF OHIO LAW; ARTICLES OF
INCORPORATION AND REGULATIONS.  Certain provisions of Ohio law, the Company's
Articles of Incorporation and  Regulations could have the effect of making it
more difficult for a third party to acquire, or of discouraging a third party
from attempting to acquire, control of the Company. The Company's Articles of
Incorporation provide for the Board of Directors to be divided into three
classes of directors serving staggered three-year terms (unless there are 
fewer than 9 Directors, in which case there will be two classes).  Such 
classification of the Board of Directors expands the time required to change 
the composition of a majority of directors and may tend to discourage a proxy 
contest or other takeover bid for the Company.  See "THE COMPANY -  Description 
of Capital Stock." Certain provisions of Ohio law and the Company's Articles of
Incorporation allow the Company to issue preferred stock (the "Company Preferred
Stock") with rights senior to those of the Company common stock without any
further vote or action by the shareholders.  The issuance of Company Preferred
Stock could decrease the amount of earnings and assets available for
distribution to the holders of the Company common stock or could adversely
affect the rights and powers, including voting rights, of the holders of the
Company common stock.  In certain circumstances, such issuance could have the
effect of decreasing the market price of the Company common stock.  See "THE
COMPANY - Description of Capital Stock."  Additionally,  upon completion of the
Merger, the directors, executive officers and existing principal shareholders of
the


                                      -17-
<PAGE>

Company and their affiliates will collectively own approximately 31% of the
outstanding Company common stock.  Such concentration of ownership may have the
effect of delaying or preventing a change in control of the Company. See "RISK
FACTORS - Control by Principal Shareholders" and "THE COMPANY - Principal
Shareholders."

     FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FINANCING.  If additional
funds are needed for the Company's operations, there can be no assurance that
such funds will be available on terms favorable to the Company, or at all.  If
additional funds are raised through the issuance of equity securities, the
percentage ownership of the then current shareholders of the Company may be
reduced and such equity securities may have rights, preferences or privileges
senior to those of the holders of the Company's common stock.

                                   THE  MERGER

BACKGROUND OF THE MERGER

     Management of the Company and the Predecessor Companies began discussing a
possible business combination in early 1995.  These discussions culminated in
the signing of a letter of intent, dated February 1, 1995,  summarizing the
discussions and understandings of the parties regarding a proposed merger of the
Company and the Predecessor Companies (the "Letter of Intent").  The Letter of
Intent did not contain specific terms or a specific structure for the
combination.  The parties to the Letter of Intent had to agree on the relative
valuation of the combining entities and certain other issues.  NSI's pending
initial public offering and disagreements with NSI involving the Company's and
the Predecessor Companies' rights under their respective license agreements with
NSI also contributed to the delay in finalizing the Merger Agreement.

     On December 5, 1995, the Company and the Predecessor Companies entered into
a Settlement Agreement with NSI, which settled all disputes with NSI as of that
date.  The Settlement Agreement included the License Agreement for the licensing
of rights to the PAPNET-Registered Trademark- System and the PAPNET-Registered
Trademark- Service that the Company and each of the Predecessor Companies
approved.  NSI also closed its initial public offering on December 7, 1995.

     In March 1996, the Company and the Predecessor Companies agreed to a merger
in which CWI and PUI were to have been parties.  CWI would have been the
surviving corporation, but that transaction was abandoned in May 1996, and the
parties decided to proceed without the participation of CWI and PUI.

REASONS FOR THE MERGER; RECOMMENDATION OF THE COMPANY'S AND PREDECESSOR
COMPANIES' BOARD OF DIRECTORS

     In evaluating the proposed Merger, the Boards of Directors of the Company
and the Predecessor Companies, with the assistance of outside counsel and other
advisors, considered a variety of factors, including the following: (i) the
efficiencies created through the combined entity; (ii) the relative market
positions of each of the Company and the Predecessor Companies and the increased
market penetration of the combined entity; (iii) the ability of management of
the combined entity to realize the full potential of the combined entity; (iv)
the opportunity that the combination would afford the Predecessor Companies'
shareholders to acquire an equity participation in a larger


                                      -19-
<PAGE>

enterprise with significantly larger equity value than any one of the
Predecessor Companies; (v) the terms of the Merger Agreement; and (vi) the
potential for greater liquidity for the shareholders of the Predecessor
Companies.

     The directors of the Company and the Predecessor Companies have unanimously
determined that the Merger Agreement and the Merger are advisable and fair and
in the best interests of the Company and the Predecessor Companies and recommend
that their respective shareholders approve the Merger Agreement and the Merger.

REQUIRED VOTE

     ERG, CCWP, and CCI are all Ohio corporations and their respective Articles
of Incorporation provide that where Ohio General Corporation Law requires the
affirmative vote of greater than a majority  of the shares entitled to vote on a
matter, that matter can be approved by a majority of the shares entitled to vote
on the matter.  Accordingly, approval of the Merger, Merger Agreement and the
transactions contemplated thereby requires the affirmative vote of the holders
of the issued and outstanding shares of ERG, CCWP, and CCI common stock
entitling them to exercise a majority of the voting power of the respective
corporations.

     The Company, CIN, and INC are also Ohio corporations, but their respective
Articles of Incorporation do not provide for majority approval of transactions
like those contemplated by the Merger and the Merger Agreement.  Accordingly,
the Merger, the Merger Agreement and the transactions contemplated thereby must
be approved by the affirmative vote of the holders of the issued and outstanding
shares of the Company, CIN, and INC common stock entitling them to exercise at
least two-thirds of the voting power of the respective corporations.

THE MERGER AGREEMENT

     The following is a brief summary of certain provisions of the Merger
Agreement, a copy of which is attached as Appendix A to this Prospectus and is
incorporated herein by reference.  Such summary is qualified in its entirety by
reference to the Merger Agreement.  Shareholders are urged to read the Merger
Agreement carefully.

     The Merger Agreement provides that, as promptly as practicable following
the approval of the Merger by the shareholders of the Company and the
Predecessor Companies and the satisfaction or waiver of the other conditions to
the Merger, but in no event later than two days thereafter, the Predecessor
Companies will be merged with and into the Company, with the Company continuing
as the surviving corporation under the name "NetMed, Inc."

     Upon the satisfaction or waiver of all conditions to the Merger, the Merger
will become effective upon the filing of a certificate of merger by the Company
and the Predecessor Companies with the Secretary of State of Ohio in accordance
with Ohio General Corporation Law.  The anticipated Effective Time is not until
September 1996.

     MERGER CONSIDERATION GENERALLY.  In the Merger, all outstanding shares of
the Predecessor Companies' common stock, including shares of Predecessor Company
common stock issuable upon


                                      -20-

the exercise of outstanding warrants and options, shall be converted into the
right to receive the Company Shares, based on the following conversion table:

     FRACTIONAL SHARES.  No fractional shares will be issued in the Merger.

     CONDITIONS TO CONSUMMATION OF THE MERGER.   The respective obligations of
the Company and the Predecessor Companies to consummate the Merger are subject
to certain conditions, including among others the adoption of the Merger and the
Merger Agreement by the holders of the requisite number of shares of the Company
and Predecessor Companies' common stock; the compliance by each of the parties
to the Merger Agreement with its material obligations thereunder and the truth
of the representations and warranties made by each of the parties on the date of
the Merger Agreement and at the Effective Time; the effectiveness of the
Registration Statement  under the Securities Act;  the receipt by the Company of
all state securities or "Blue Sky" permits and other authorizations necessary to
issue the Company Shares pursuant to the Merger and the Merger Agreement; the
admission of the Company for quotation on the National Market of the National
Association of Securities Dealers, Inc. Automated Quotation system ("NASDAQ
NMS") upon official notice of issuance;  at the  Closing, the shareholders of
the Company or any Predecessor Company entitled to assert dissenter's rights
shall own in the aggregate less than 10% of the outstanding shares of the
Company or such Predecessor Company; and the receipt by the Company and the
Predecessor Companies of an opinion of Porter, Wright, Morris & Arthur, counsel
to the Company, to the effect that, among other things that, the Merger will be
treated for federal income tax purposes as a reorganization within the meaning
of Section 368(a) of the Code and each Predecessor Company will be a party to
that reorganization within the meaning of Section 368(b) of the Code.

     REPRESENTATIONS AND WARRANTIES.  In the Merger Agreement, each of the
Predecessor Companies and the Company has made certain representations and
warranties relating to, among other things:  (i) its corporate organization and
qualification; (ii) its capitalization; (iii) its corporate power and authority
relative to the Merger Agreement; (iv) the absence of conflicts with its
constituent documents and material agreements; (v) filings required to be made
with and consents required to be obtained from governmental entities in
connection with the transactions contemplated by the Merger Agreement; (vi)
the accuracy of the information supplied for this prospectus and the
Registration Statement; and (vii) the absence of changes that would have a
material adverse effect on the properties, assets, financial condition,
operating results or business.


                                      -21-
<PAGE>

     CERTAIN AGREEMENTS AND COVENANTS.  Pursuant to the Merger Agreement, each
of the Predecessor Companies and the Company agree that, without the consent of 
the other parties, among other things:  (i) each party will carry on its 
respective businesses as usual, regular and ordinary course, consistent with
past practice; (ii) it will not amend its articles of incorporation or code of
regulations; (iii) it will not cause a split, combination, or re-classification
of any of its outstanding capital stock; (iv) it will not cause the declaration,
setting aside or payment of any dividend; (v) it will not cause the redemption,
purchase, acquisition, or offer to acquire, of any shares of capital stock; (vi)
it will not cause the issuance, sale, pledge, or disposition of, or agreement to
issue, sell, pledge, or dispose of, any stock of, or securities convertible or
exchangeable for, or any option, warrant or right of any kind to acquire any
shares of capital stock of any class of  stock or other securities or equity
equivalents (other than pursuant to the exercise of currently outstanding
options or warrant); (vii) it will not incur or guarantee of any indebtedness
for borrowed money other than in the ordinary course of business consistent with
past practice; or (viii) no party shall change any of the accounting principles
or practices used by it (except as required by GAAP).

     LOCK-UP AGREEMENT.  Under the terms of the Merger Agreement, the
Predecessor Company shareholders have, with respect to the Company shares that
each receives in the Merger, and David J. Richards, John P. Kennedy and Carl A.
Genberg (the "Key Company Shareholders") have, with respect to their shares of
the Company, agreed to certain additional restrictions on the transfer of their
respective shares of the Company.  Except with respect to certain privately
negotiated sales, the Predecessor Company shareholders will be prohibited from
selling more than an aggregate of 625,000 Company Shares during the one year
period commencing on the closing date of the Merger.  The number of Company
Shares that each Predecessor Company shareholder will be entitled to sell is
equal to the product of (A) the ratio of Company Shares received with respect to
the conversion of the shareholder's shares in a Predecessor Company to the
number of Company Shares so received by all shareholders of such Predecessor
Company, times (B) the number of shares allocated to such Predecessor Company in
the Merger Agreement for the relevant time period.  Except with respect to
certain privately negotiated sales and certain transactions involving the pledge
of the shares held by the Key Company Shareholders, the Key Company Shareholders
have agreed not to sell the Company Shares they own immediately after the Merger
for a period of one year commencing on the closing of the Merger.  See "Merger
Agreement - Appendix A."

     TERMINATION.   The Merger Agreement may be terminated by mutual consent of
all of the parties; by any of the parties if the Merger shall not have been
consummated before September 30, 1996 (unless the failure to consummate the
Merger by such date shall be due to the action or failure to act of the party
seeking to terminate the Merger Agreement); by any party if any permanent
injunction or other order of a court or other competent authority shall have
become final and non-appealable; or by any party if any required approval of the
shareholders of such party or any other party shall not have been obtained.   In
the event that the Merger Agreement is terminated, the Merger Agreement shall be
void and have no effect, without any liability on the part of any party or its
affiliates, directors, officers, or shareholders.  Notwithstanding the
foregoing, the parties to the Merger Agreement will continue to be bound by the
provisions of the Merger Agreement that relate to: (i) their respective
obligations as to confidentiality and the payment of any broker's or finder's
fees; (ii) a party's obligation to pay liquidated damages in the amount of
$500,000 to the other parties if the termination arises out of that party's
failure to obtain the required approval of the Merger and


                                      -22-
<PAGE>

the Merger Agreement or that party's breach of the Merger Agreement; and (iii) a
party's obligation to pay its share of all costs and expenses incurred by the
parties in connection with the Merger and the transactions contemplated by the
Merger Agreement.  A party's share of any liquidated damages paid as a result of
a termination of the Merger  or its share of costs and expenses required to be
paid under the Merger Agreement shall be in proportion to the number of the
Company Shares that would have been owned by the party's shareholders
immediately after the Effective Time.

     The Merger Agreement may also be terminated by a majority vote of the
members of the Advisory Board.

EXCHANGE OF CERTIFICATES

       The Huntington National Bank, N.A., the Company's transfer agent (the
"Exchange Agent"), will mail to each holder of record of Predecessor Company
shares a letter of transmittal and instructions for use in effecting the
surrender of the Predecessor Company certificates  (the "Certificates") in
exchange for certificates representing the Company's common stock.  Upon
surrender of a Certificate to the Exchange Agent, together with a letter of
transmittal, duly executed, the holder of the Certificate shall be entitled to
receive in exchange therefor the certificates representing the shares of common
stock of the Company in accordance with the provisions of the Merger Agreement.

AMENDMENT TO ARTICLES OF INCORPORATION

     At the Effective Time and upon the filing of the Certificate of Merger with
the Ohio Secretary of State, the Company's Articles of Incorporation will be
amended to, among other things: change the name of the Company to "NetMed,
Inc."; increase the Company's authorized capital stock to 15,500,000 shares,
consisting of 15,000,000 shares of common stock and 500,000 shares of preferred
stock;  establish standards by which the Board of Directors must evaluate any
proposal that would result in a change of control; and provide that the
provisions of the Articles of Incorporation that relate to the powers, duties
and liabilities of the directors may only be amended by affirmative vote of 80%
of the outstanding shares entitled to vote on the matter.

DISSENTER'S RIGHTS

     THE FOLLOWING DISCUSSION IS NOT A COMPLETE STATEMENT OF THE LAW PERTAINING
TO DISSENTING SHAREHOLDER RIGHTS UNDER THE OHIO GENERAL CORPORATION LAW AND IS
QUALIFIED IN ITS ENTIRETY BY THE FULL TEXT OF SECTION 1701.85 WHICH IS REPRINTED
IN ITS ENTIRETY AS APPENDIX B TO THIS PROSPECTUS.

     The Company, CIN, INC, ERG, CCWP, and CCI are all Ohio corporations.
Shareholders of any of the parties who (i) are shareholders of record on the
record date established for determining who is entitled to notice of the meeting
called for the purpose of approving the Merger, (ii) do not vote in favor of the
Merger, and (iii) who, within 10 days after the date of the vote on the Merger
is taken, deliver written demand in compliance with the provisions of Section
1701.85(A)(2) of the Ohio Revised Code, shall be entitled to receive the fair
cash value of the shares that were not voted in favor of the Merger (the
"Dissenting Shares").  The written demand must set forth the


                                      -23-
<PAGE>

shareholder's address, the number and class of stocks as to which the
stockholder seeks relief and the amount the shareholder claims as the fair cash
value of the Dissenting Shares.

     If a constituent corporation receives a written demand from a shareholder
seeking the fair cash value of Dissenting Shares, it may request the certificate
or certificates that represent the Dissenting Shares.  The dissenting
shareholder must deliver the certificate or certificates representing the
Dissenting Shares to the corporation within 15 days of the date of its request
therefor or the shareholder's rights with respect to the Dissenting Shares will
terminate.  If the certificate or certificates representing the Dissenting
Shares are delivered to constituent corporation, it must promptly endorse the
certificates with a legend to the effect that a demand for the fair cash value
for the Dissenting Shares has been made and return the certificates to the
dissenting shareholder.

     If the Company and the dissenting shareholder cannot agree on the fair cash
value of the Dissenting Shares, then either may, within three months after the
date of the service of the demand for fair cash value was made by the dissenting
shareholder file a complaint in the court of common pleas of the county in which
the principal office of the corporation that issued the Dissenting Shares is
located or was located when the Merger proposal was adopted by the shareholders
of that corporation.  The court will first make a determination if the
dissenting shareholder is entitled to receive the fair cash value for the
Dissenting Shares.  If the court determines that the dissenting shareholder is
entitled to fair cash value for the Dissenting Shares, the court will appoint an
appraiser or appraisers to make a finding as to the fair cash value of the
Dissenting Shares.

     The fair cash value will be determined based on what a willing seller who
is under no compulsion to sell would be willing to accept and that which a
willing buyer who is under no compulsion to purchase would be willing to pay for
the Dissenting Shares.  In no event will the fair cash value exceed the amount
stated in the written demand by the dissenting shareholder.    In computing the
fair cash value, any appreciation or depreciation in the market value resulting
from the Merger shall be excluded.

     The fair cash value that is agreed upon between the parties or that is
determined by the court  shall be paid within 30 days after the date of the
final determination of such value or the consummation of the Merger, whichever
occurs last.  Payment shall be made only upon and simultaneously with the
surrender to the Ohio Corporation of the certificate or certificates 
representing the Dissenting Shares.

     The costs of the action, including reasonable compensation to the
appraisers, will be fixed by the court and will be assessed or apportioned as
the court considers equitable.

     A shareholder's right to receive the fair cash value for the Dissenting
Shares terminates if (i) the dissenting shareholder does not strictly comply
with the requirements of Section 1701.85, (ii) the Merger is abandoned, (iii)
the dissenting shareholder withdraws the demand for fair cash value, or (iv) the
Company and the dissenting shareholder have not come to an agreement regarding
the fair cash value of the Dissenting Shares and neither has filed a complaint
with the court of common pleas within the time period described in Section
1701.85(B).

     FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 1701.85 OF THE OHIO GENERAL
CORPORATION LAW FOR PERFECTING DISSENTING SHAREHOLDER RIGHTS MAY RESULT IN THE
LOSS OF SUCH RIGHTS (IN WHICH EVENT AN OHIO CORPORATION SHAREHOLDER WILL BE 
ENTITLED TO RECEIVE THE CONSIDERATION RECEIVABLE WITH RESPECT TO SUCH 
SHARES IN ACCORDANCE WITH THE MERGER AGREEMENT).

NASDAQ/NMS

     One of the conditions to the consummation of the Merger is that its common
stock will be admitted for quotation on NASDAQ/NMS, subject to official notice
of issuance.


UNAUDITED PRO FORMA CONDENSED COMBINING FINANCIAL INFORMATION

     The merger will be effected by an exchange of the Company's common stock
for the outstanding common shares of the Predecessor Companies.  This exchange
transaction will occur in connection with the initial registration of the
Company's common stock with the Securities and Exchange Commission and will
result in the public trading of the common stock which is expected to be on the
NASDAQ/NMS.  The merger of the Company and the Predecessor Companies will be
accounted for at historical cost.  This accounting reflects the level of common
ownership (shareholders) and common management (officers and directors) that
exists between the Company and Predecessor Companies.  It also recognizes the
lack of objective criteria for valuing the merger transaction.  For accounting
purposes, the Company will be the predecessor of the merged entity and its
historical financial statements will be those of the new entity NetMed, Inc.
The results of operations of the Predecessor Companies will be combined with
those of the Company commencing at the date of merger.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following discussion is a general summary of the principal federal
income tax consequences of the Merger to individual United States holders of the
Predecessor Companies  shares who hold their shares as capital assets.  The
discussion is based on laws, regulations, rulings and decisions currently in
effect.  It is for general information only, and is not intended to be tax
advice to any particular shareholder of the Company or a Predecessor Company.
The discussion does not take into account rules that are applicable to
shareholders of the Predecessor Companies that are subject to special treatment
under the Code, including without limitation, insurance companies, dealers in
securities, financial institutions, tax-exempt investors, foreign investors,
shareholders who do not hold their stock as a capital asset and shareholders who
acquired shares pursuant to the exercise of an employee stock option, employee
stock purchase plan or otherwise as compensation.  The discussion also does not
address state, local or foreign tax consequences of the Merger.  No rulings have
been or will be requested from the IRS with respect to the tax consequences of 
the Merger.


                                      -25-
<PAGE>

     Assuming the Merger is consummated in the manner set forth in the Merger
Agreement and qualifies as a reorganization under Section 368 of the Code, the
principal federal income tax consequences of the Merger under present federal
income tax law will be as described below.

     (a)  No gain or loss will be recognized by the Company or the Predecessor
          Companies as a result of the Merger;

     (b)  No gain or loss will be recognized by the holders of Predecessor
          Company shares upon the exchange of their shares of Predecessor
          Company shares for Company Shares pursuant to the Merger (except for
          any gain or loss attributable to cash received by a holder of
          Predecessor Company stock in payment of appraisal or dissenters'
          rights of appraisal or for fractional share interests to which they
          may be entitled );

     (c)  The federal income tax basis of the Company Shares received by the
          shareholders of the Predecessor Companies (including fractional share
          interests to which they may be entitled) for their Predecessor Company
          shares will be the same as the federal income tax basis of the
          Predecessor Company shares surrendered in exchange therefor, increased
          by any gain recognized; and

     (d)  The holding period for the Company Shares received by shareholders of
          the Predecessor Companies in exchange for their Predecessor Company
          shares will include the period for which the Predecessor Company
          exchanged therefor were held, provided that the exchanged Predecessor
          Company shares were held as a capital asset by such shareholder on the
          date of the exchange.

     It is a condition to the closing that the Company and the Predecessor
Companies shall have received an opinion of Porter, Wright, Morris & Arthur
which will be based upon certain certificates, representations and assumptions,
substantially to the effect that, for federal income tax purposes the Merger
will constitute a reorganization within the meaning of section 368(a) of the
Code and will result in the tax consequences described above.

     No opinion will be expressed with respect to any other tax consequences of
the exchange, including, without limitation, the tax consequences with respect
to any shares of Predecessor Company stock that were acquired in contemplation
of the Merger, were held by shareholders subject to special treatment under the
Code, were not held as capital assets or were acquired by the holder thereof
pursuant to any employee stock option, employee stock purchase plan or otherwise
as compensation or pursuant to the exercise of any warrants to purchase shares
of Predecessor Company stock.  Further, no opinion is expressed concerning the
effect of state, local and foreign tax laws.  An opinion of counsel is not
binding upon the IRS, and there can be no assurance that the IRS will not take a
position contrary to the positions reflected in such opinion or that such
opinion will be upheld by the courts if challenged by the IRS.

     THE SPECIFIC TAX TREATMENT OF EACH SHAREHOLDER WILL DEPEND ON THEIR
PARTICULAR FACTS AND CIRCUMSTANCES.  EACH HOLDER OF COMPANY SHARES AND
PREDECESSOR COMPANY SHARES IS ADVISED TO CONSULT WITH SUCH STOCKHOLDER'S OWN TAX
ADVISER CONCERNING THE FEDERAL INCOME TAX


                                      -26-
<PAGE>

CONSEQUENCES OF THE MERGER, AS WELL AS THE APPLICABLE STATE, LOCAL, FOREIGN OR
OTHER TAX CONSEQUENCES.

     BACKUP WITHHOLDING.  Under federal income tax law concerning "backup
withholding,"  the Company will be required to withhold, and will withhold, 31%
of any cash payments to which a shareholder is entitled pursuant to the Merger
unless the holder provides its taxpayer identification number ("TIN") and
certifies that such number is correct or otherwise establishes that the holder
is an exempt holder (such as a corporation or certain foreign individuals,
partnerships or trusts).  In general, the TIN of an individual shareholder is
that shareholder's social security number.  Each holder should sign the
Substitute Form W-9 included as part of the Transmittal Letter (or in the case
of a nonresident alien or foreign entity, a Form W-8) to prevent backup
withholding.

RESALES BY AFFILIATES

     The Company Shares issuable in the Merger will have been registered under
the Securities Act but will not be freely transferable if held by persons,
including directors and executive officers of the Predecessor Companies, who may
be deemed to be "affiliates" of  the Predecessor Companies  for purposes of Rule
145.  Affiliates may not offer to sell, sell or otherwise dispose of Company
Shares issued to them in connection with the Merger, except (i) pursuant to an
effective registration statement under the Securities Act covering those shares,
(ii) in compliance with Rule 145, or (iii) pursuant to an exemption from the
registration requirements of the Securities Act.  The Company intends to obtain
customary agreements with all affiliates of the Predecessor Companies under
which those persons shall agree not to dispose of the Company Shares received by
them in the Merger, except in compliance with the Securities Act and the rules
and regulations promulgated thereunder.  The Company shall be entitled to place
appropriate legends on the certificates evidencing the Company Shares to be
received by such affiliate pursuant to the terms of the Merger, and to issue
appropriate stock transfer instructions to the transfer agent for Company
Shares, to the effect that the shares received or to be received by such
affiliate pursuant to the Merger may only be sold, transferred or otherwise
conveyed, and the holder thereof may only reduce his interest in or risks
related to such shares, pursuant to an effective registration statement under
the Securities Act or in accordance with the provisions of paragraph (d) of Rule
145 or pursuant to an exemption from registration provided under the Securities
Act.  The foregoing restrictions on the transferability of the Company Shares
shall apply to all purported sales, transfers and other conveyances of the
shares received or to be received by such affiliate pursuant to the Merger and
to all purported reductions in the interest in or risks relating to such shares,
whether or not such affiliate has exchanged the certificates previously
evidencing shares of  the Predecessor Company common stock.  This Prospectus
does not cover any resales of the Company Shares received by affiliates of the
Predecessor Companies.

     Under the terms of the Merger Agreement, the Predecessor Company
shareholders have, with respect to the Company shares that each receives in the
Merger, and the Key Company Shareholders have, with respect to their shares 
of the Company, agreed to certain additional restrictions on the transfer of 
their respective shares of the Company.  Except with respect to certain 
privately negotiated sales, the Predecessor Company shareholders will be 
prohibited from selling more than an aggregate of 625,000 Company Shares during 
the one year period commencing on the closing date of the Merger.  The number 
of Company


                                      -27-
<PAGE>

Shares that each Predecessor Company shareholder will be entitled to sell is
equal to the product of (A) the ratio of Company Shares received with respect to
the conversion of the shareholder's shares in a Predecessor Company to the
number of Company Shares so received by all shareholders of such Predecessor
Company, times (B) the number of shares allocated to such Predecessor Company in
the Merger Agreement for the relevant time period.  Except with respect to
certain privately negotiated sales and certain transactions involving the pledge
of the shares held by the Key Company Shareholders, the Key Company Shareholders
have agreed not to sell the Company Shares they own immediately after the Merger
for a period of one year commencing on the closing of the Merger.  See "Merger
Agreement - Appendix A."

                          CERTAIN RELATED TRANSACTIONS

     Each of the other Predecessor Companies and the Company entered into a 
Loan Agreement, dated July 5, 1996 (the "Loan Agreement"), whereby the 
Company has agreed to advance to the other Predecessor Companies the expenses 
incurred by each in connection with the Merger.  In addition, the Company 
will advance funds necessary to pay reasonable expenses of ordinary business 
operations for the Predecessor Companies pending consummation of the Merger 
(collectively the "Advancer").   The advances made to the Predecessor 
Companies in connection with the merger that was abandoned in June 1996 (the 
"Initial Advances") will be added to the Advances.  The Initial Advances and 
the Advances will be evidenced by a promissory note bearing interest at an 
annual rate of 7%, payable 180 days after the earlier of the consummation of 
the Merger or the termination of the Merger Agreement.  Promissory notes 
delivered by the Predecessor Companies will be secured by their shares of NSI 
common stock.

     The Loan Agreement has been modified by a side-letter agreement among the
Company, ERG, CCI and CCWP, dated July 16, 1996, which provides, among other
things, terms relating to notice and cure periods for any defaults and credits
for certain expenses that are paid directly by these Predecessor Companies.

     The Company entered into a loan agreement, dated March 14, 1996 with 
Cytology West, Inc. ("CWI") and Papnet Utah, Inc. ("PUI") CWI is licensed to 
sell the PAPNET-Registered Trademark- System and the PAPNET-Registered 
Trademark- Service in Arizona, Nevada and San Diego County California.  PUI 
is licensed to sell PAPNET-Registered Trademark- System and the 
PAPNET-Registered Trademark- Service in Utah.  Carl Genberg, President of 
CWI, owns 383,616 shares of the Company's common stock and may be deemed to 
be an affiliate of the Company.  CWI and PUI were originally to have been a 
parties to a merger with the Company and the Predecessor Companies, but that 
transaction was abandoned by the parties.  The loan agreement provides for 
advances to CWI of up to $585,000 to cover certain operating expenses, 
expenses associated with the abandoned merger, and the acquisition of new 
technology.  No specific amount was established for advances to PUI.  The 
advances will bear interest at the rate of 7% per annum.  As of June 15, 
1996, the Company had advanced approximately $146,320 to CWI and $14,315 to 
PUI under the terms of the loan agreement, and no further advances will be 
made.

     The Company, the Predecessor Companies and certain individual shareholders
of these companies entered into a Voting Agreement, dated July 5, 1996, pursuant
to which the individual shareholders appointed John P. Kennedy and Cecil J.
Petitti as their proxies and attorneys-in-fact for


                                      -28-
<PAGE>

the purpose of voting their shares in the Company or Predecessor Company, as the
case may be, in favor of the Merger, the Merger Agreement and the transactions
contemplated thereby.

     Pending completion of the Merger, the business operations of CIN, INC, ERG,
and CCI are being managed by the Company.


                                   THE COMPANY

GENERAL

     The Company is an Ohio corporation formed on October 25, 1989 for the
purpose of acquiring the exclusive rights to market certain proprietary products
of NSI in the State of Ohio.  On December 29, 1989, Papnet Limited Partnership
("PLP") was formed with the Company as its general partner and the Company
assigned its marketing rights to the PAPNET-Registered Trademark- System to PLP.
Papnet Midwest Limited Partnership ("PMLP") was formed on April 6, 1990 with the
Company as its general partner and PMLP acquired the rights to market the
PAPNET-Registered Trademark- System in Kentucky and the Standard Metropolitan
Statistical Area of Chicago, Illinois.  In January 1993, the Company acquired
all of the issued and outstanding units of limited partnership interest in both
PLP and PMLP and thereby acquired all of their respective rights to market the
PAPNET-Registered Trademark- System in Ohio, Kentucky and the Standard
Metropolitan Area of Chicago, Illinois.

NSI

     Neuromedical Systems, Inc. ("NSI"), founded in 1988, is an emerging health
care service company focused on value-added diagnostic screening applications to
aid in the early detection of cancer of several body sites.  NSI's first
product, the PAPNET-Registered Trademark- System, has been shown in a series of
controlled clinical trials to allow pathology laboratories to detect abnormal
cells on cervical Papanicolaou ("Pap") smears which were not detected by the
standard manual microscopic inspection. This improved detection can result in
more effective and less costly early treatment, reduced possibility of morbidity
and mortality for the patient, and reduced possibility of malpractice litigation
for the patient's doctor and laboratory. On September 21, 1994 NSI submitted an
application to the U.S. Food and Drug Administration ("FDA") to market the
PAPNET-Registered Trademark- System in the United States for routine clinical
use, supported by clinical trial data indicating that PAPNET-Registered
Trademark- System would have resulted in earlier detection of disease for many
patients (see below). The PAPNET-Registered Trademark- System can achieve these
improvements without requiring a modification of the standard Pap smear sample
due to its patented use of a combination of algorithmic and neural network
pattern recognition technology.  By June 1996, PAPNET-Registered Trademark-
System was already in routine clinical use in 21 countries worldwide.  Because
the  PAPNET-Registered Trademark- System has now been approved by the FDA, NSI
intends to increase the scale of its operations to commercial levels.  NSI is

THE MARKET

     Pap smears are widely used in North America, Europe and other developed
areas to aid in the early detection of cervical cancer with over 50 million
tests performed annually in the U.S. alone. Pap smears can reveal early changes
in cervical cells that precede or indicate the development of cancer, thereby
facilitating timely medical intervention. When cervical cancer or precancerous
conditions are detected early on a Pap smear, the disease is almost always
completely curable using a simple outpatient procedure. However, if abnormal
cells on the Pap smear are not noticed by the laboratory, the patient may be
falsely told that her Pap smear is negative (a "false negative"), with
significant morbidity or mortality occurring as a result. Failure to diagnose
cervical cancer is a significant and rapidly growing source of malpractice
litigation against laboratories and clinicians in both the U.S. and abroad.

     Manual searching of routine Pap smears to spot abnormal cells is an
unavoidably tedious and error-prone task. This is primarily because a seriously
abnormal Pap smear can contain fewer than a dozen abnormal cells scattered among
hundreds of thousands of normal cells and other objects. The cytotechnologist's
job is thus very similar to proofreading a very long document to try to detect a
few misspelled words. Regardless of how conscientious and careful the laboratory
is, many of these "needles in a haystack" may be missed, and the patient falsely
informed that her Pap smear was negative. Manual screening false-negative rates
ranging from 10% to 40% have been reported in numerous published studies.  The
PAPNET-Registered Trademark-  System has been shown in several domestic and
international clinical studies published in peer-reviewed journals to detect
abnormal cells on Pap smears that were falsely diagnosed as "negative" by
conventional manual inspection. Indeed, in a number of such cases
PAPNET-Registered Trademark- System detected abnormal cells on archived,
supposedly "negative" Pap smears of women who were ultimately diagnosed with
advanced cervical cancer. A published review of six such studies which in the
aggregate evaluated 513 Pap smears known to contain precancerous or cancerous
abnormality reported a pooled average PAPNET-Registered Trademark- false
negative rate of 3%.  These results compare extremely favorably to manual
screening's false negative rate, typically reported to be many times higher (10%
to 40%).

THE PAPNET-Registered Trademark- SYSTEM

     The PAPNET-Registered Trademark- System is a computer-based system which
allows the cytotechnologist at the referring laboratory to review a slide by
viewing a small number of computer selected cells on a high resolution, color
video monitor.  The PAPNET-Registered Trademark- System consists of a scanning
system (the "Scanner"), which processes slides and stores digital images of
certain portions of the slides on a digital tape, and a proprietary review
station (the "Review Station"), which, among other things, permits a
cytotechnologist trained by NSI to review the images stored on the digital tape.

     The  PAPNET-Registered Trademark-  System is used as a supplement to
current practice and does not alter the clinician's or pathology laboratory's
existing smear preparation or manual screening procedures in any way.  It
provides an additional and complementary level of screening for the purpose of
decreasing false negative Pap smear diagnosis.


                                      -30-
<PAGE>

     The  PAPNET-Registered Trademark-  System provides a semi-automated search
for abnormal cells which may have been missed on initial, manual screening.  It
addresses those aspects of the cervical smear screening process which most
affect the false negative rate: the psychological habituation and fatigue
associated with the "needle in a haystack," repetitive search for a small number
of abnormal cells distributed among hundreds of thousands of normal cells.  The
PAPNET-Registered Trademark-  System is only used to aid in the rescreening of
slides which are diagnosed by manual inspection to be "negative" and which would
otherwise be sent to the laboratory's archive without further examination.  The
system is semi-automated in that it does not attempt to provide a diagnosis, but
only points out potentially abnormal cells to the cytotechnologist, thus
retaining and enhancing the ability of trained cytotechnologists to evaluate and
interpret cytological evidence.

      The Scanner operates continuously and virtually unattended, selecting 128
cells from each slide which appear most suspect to the system.  The Review
Station is installed in the cytotechnologist's work area of the referring
laboratory.  The Scanner includes an automated microscope, a primary high speed
image classifier, and a secondary neural network based classifier.  The Review
Station includes a high resolution color video monitor, video display cards, and
an Intel compatible computer.  NSI was granted a patent for technology used in
the PAPNET-Registered Trademark- System, which enables automated analysis of the
conventionally prepared smear.  NSI and the Company enroll and train
laboratories to use the PAPNET-Registered Trademark- System as a rescreening
device in NSI's clinical investigation.  The PAPNET-Registered Trademark- System
is in use in numerous foreign countries, where the scope of use permitted by
regulatory authorities is generally much broader than is currently the case in
the United States.

THE PAPNET-Registered Trademark- SERVICE

     NSI markets and sells PAPNET-Registered Trademark- Testing as a service, by
which end-user laboratories submit slides to one of NSI's central facilities for
processing on a Scanner and NSI returns such slides and the related digital tape
containing the images to the laboratories so that NSI-trained cytotechnologists
employed by the laboratories may review the slides and images using the Review
Station.  The Company is licensed to market the PAPNET-Registered Trademark-
Service.

THE LICENSE

    On December 5, 1995 the Company, the Predecessor Companies and CWI and PUI
who are not parties to the Merger, entered into a Settlement Agreement with NSI
(the "Settlement Agreement").   The purpose of the Settlement Agreement was to
resolve and clarify certain issues relating to the license agreements which NSI
had with its regional licensees, and issues relating to warrants to purchase
shares of NSI common stock which were held by the Company and certain of the
Predecessor Companies.  Pursuant to the Settlement Agreement, NSI and the
regional licensees (including the Company and all of the Predecessor Companies
except CCWP) agreed to the form of a license agreement to be executed upon the
merger of some or all of the regional licensees (the "License Agreement"), under
which the Company and the other regional licensees will continue to have the
rights to market the PAPNET-Registered Trademark- System and PAPNET-Registered
Trademark- Service, as well as certain other medical technologies which may be
developed by NSI ("NSI Technology").  In the event that the Merger is not
consummated as anticipated, NSI will enter into separate license agreements
which each of the regional licensees on substantially the same terms as the
License Agreement.  NSI and the regional licensees have agreed to operate under
the terms of the License Agreement until such agreement or agreements are
executed following consummation of the Merger.

     Upon consummation of the Merger, the Company will have the exclusive right
and license of sell the PAPNET-Registered Trademark- System, PAPNET-Registered
Trademark- Service and NSI Technology in the states of Ohio, Georgia, Kentucky,
Missouri, North Carolina and in the Standard Metropolitan Statistical Area of
Chicago, Illinois.

     The License Agreement provides that the regional licensees will be paid
royalties as follows:  (a) monthly royalties equal to 50% of the amount by which
NSI's gross revenues from sales in the licensed territories exceed the cost of
processing slides originating in the licensed territories (for purposes of which
calculation costs per slide may not exceed $1.00 per slide) and the cost of
transporting such slides, with the maximum amount of such monthly royalties in
any fiscal year capped at an amount derived by applying the royalty formula to
12,175,000 slides; (b) annual royalties equal to the difference, if any, by
which aggregate monthly royalties in any fiscal year are less than 4.15% of
NSI's worldwide gross revenues for such fiscal year, with the maximum annual
royalty amount in any fiscal year capped at $23,000,000, less the amount of
monthly royalties paid in such fiscal year calculated as described in clause
(a).  For the purposes of calculating the numbers of slides attributable


                                      -31-
<PAGE>

to the licensed territories which are submitted by certain large laboratories
operating in multiple states ("Multistate National Laboratories"), there will be
attributed to each territory a proportionate number of slides submitted to NSI
for processing from all Multistate National Laboratories equal to the ratio that
the population of such territory bears to the population of the United States
(determined according to official U.S. Census data).

     The royalty calculations described in the foregoing paragraph are 
aggregate calculations for all of the territorial licensees.  Following 
consummation of the Merger, the amounts allocable to the Company will be 
determined according to the population of the geographic areas exclusively 
licensed to the Company. The applicable number of slides for the slide 
royalty cap described in clause (a) in the foregoing paragraph, the worldwide 
revenue percentage described in clause (b) in the foregoing paragraph, and 
the $23,000,000 amount described in the same clause, will be adjusted based 
upon the census data available at the time of the Merger.

      The License Agreement has an initial term that expires on December 31,
2025.  The Company has the right to extend the License Agreement for an
additional 20 year term upon written notice to NSI within six months preceding
the expiration of the initial term and upon payment of a renewal fee, which is
based on the net present value at the time of such notice of 20 years of
royalties.

     The License Agreement may not be terminated or cancelled except upon
expiration of its initial or renewal term or by written agreement of the
parties.

     ($13.38 on December 29, 1995).  An option is in-the-money if the fair
     market value of the underlying shares exceeds the exercise price of the
     option.

1995 STOCK OPTION PLAN

      The Company's Amended 1995 Stock Option Plan (the "1995 Plan") has been 
approved by the Company's Board of Directors and adopted by the shareholders 
in September 1995.  The 1995 Plan provides for the grant of options to key 
associates, officers, directors, consultants and advisers who render services


                                      -35-
<PAGE>

to the Company for the purchase of up to 150,000  Company Shares.  The options
may be either Incentive Options or Nonqualified Options.

     The 1995 Plan is to be administered by the Board of Directors of the
Company, which may, to the fullest extent permitted by law, delegate all or any
of its powers under the 1995 Plan to a committee, consisting of not fewer than
two members of the Board of Directors (the "Committee").  If the Company Shares
are registered under Section 12 of the Exchange Act, all members of the
Committee will be "disinterested persons" as defined in Rule 16b-3(c)(2)(i)
promulgated under the Exchange Act, and "outside directors", as defined in
Section 162(m) of the Code.  The Board of Directors or the Committee will be
authorized, subject to the provisions of the 1995 Plan, to determine to whom and
at what time the stock options may be granted, the designation of the option as
either an Incentive Option or Nonqualified Option, the per share exercise price,
the duration of each option, the number of shares subject to each option, any
restrictions on such shares, the rate and manner of exercise, and the timing and
form of payment.

     Under the 1995 Plan, an Incentive Option may not have an exercise price
less than fair market value of the Company Shares on the date of grant or an
exercise period that exceeds ten years from the date of grant and is subject to
certain other limitations which allow the optionholder to qualify for favorable
tax treatment.  None of these restrictions will apply to the grant of
Nonqualified Options, which may have an exercise price less than the fair market
value of the underlying Company Shares on the date of grant and may be
exercisable for an indeterminate period of time. 

     The exercise price of an option under the 1995 Plan may be paid in cash or,
with the consent of the Board of Directors or the Committee, (i) by tendering
previously acquired Company Shares valued at their fair market value on the date
they are tendered, (ii) by delivery of a full recourse promissory note for the
portion of the exercise price in excess of the par value of the shares subject
to the option, the terms and conditions of which will be determined by the Board
of Directors or the Committee, and in cash for the par value of the shares,
(iii) by any combination of the foregoing methods, or (iv) by delivery of
written instructions to forward the notice of exercise to a broker or dealer and
to deliver to a specified account a certificate for the shares purchased upon
exercise of the option and a copy of irrevocable instructions to the broker or
dealer to deliver the purchase price of the shares to the Company.

     Under the 1995 Plan, an option is not transferable except by will or by the
laws of descent and distribution and may be exercised, during the lifetime of
the optionee, only by the optionee or by the optionee's guardian or legal
representative.

     Any option granted under the 1995 Plan will terminate automatically (i) 30
days after the employee's termination of employment with the Company (other than
by reason of death or disability or for cause), (ii) one year after the
employee's death or termination of employment by reason of disability unless the
option expires earlier by its terms and (iii) on the effective date of a
termination for cause.  Options not exercisable as of the date of a change in
control of the Company will become


                                      -36-
<PAGE>

exercisable immediately as of such date.  The 1995 Plan will terminate on the
tenth anniversary of its effective date, unless earlier terminated by the Board
of Directors.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF  THE COMPANY AND THE PREDECESSOR COMPANIES

OVERVIEW

     The Company is an Ohio corporation formed on October 25, 1989 for the
purpose of acquiring the exclusive rights to market certain proprietary products
of Neuromedical Systems, Inc., a Delaware corporation ("NSI"), including the
right to sell the PAPNET-Registered Trademark- System and PAPNET-Registered
Trademark- Service in the State


                                      -37-
<PAGE>

of Ohio.  The Company later assigned its rights to Papnet Limited Partnership,
an Ohio limited partnership ("PLP").  In January 1993, the Company acquired all
of the issued and outstanding units of limited partnership interest in both PLP
and Papnet Midwest Limited Partnership, an Ohio limited partnership ("PMLP").
PMLP owned the rights to market the PAPNET-Registered Trademark- System and
PAPNET-Registered Trademark- Service in Kentucky and the Standard Metropolitan
Statistical Area of Chicago, Illinois.  As a result of these acquisitions the
Company has the rights to the PAPNET-Registered Trademark- System and
PAPNET-Registered Trademark- Service in Ohio, Kentucky and the Standard
Metropolitan Statistical Area of Chicago.

     The PAPNET-Registered Trademark- System was approved by the FDA for
commercial use in the United States on November 8, 1995.  Prior to that time,
the PAPNET-Registered Trademark- System was permitted to be utilized in the
United States on an investigational basis only, and NSI was permitted to derive
revenue with respect thereto only to recover certain of its costs.  NSI,
however, has sold PAPNET testing services for commercial use outside of the
United States.  As a result, prior to FDA approval, the Company was able to earn
revenues based upon the worldwide revenue calculation as described below.

     On December 5, 1995 the Company, the Predecessor Companies and CWI and PUI
who are not parties to the Merger, entered into a Settlement Agreement with NSI
(the "Settlement Agreement").   The purpose of the Settlement Agreement was to
resolve and clarify certain issues relating to the license agreements which NSI
had with its regional licensees, and issues relating to warrants to purchase
shares of NSI common stock which were held by the Company and certain of the
Predecessor Companies.  Pursuant to the Settlement Agreement, NSI and the
regional licensees (including the Company and all of the Predecessor Companies
except CCWP) agreed to the form of a license agreement to be executed upon the
merger of some or all of the regional licensees (the "License Agreement"), under
which the Company and the other regional licensees will continue to have the
rights to market the PAPNET-Registered Trademark- System and PAPNET-Registered
Trademark- Service, as well as certain other medical technologies which may be
developed by NSI ("NSI Technology").  In the event that the Merger is not
consummated as anticipated, NSI will enter into separate license agreements
which each of the regional licensees on substantially the same terms as the
License Agreement.  NSI and the regional licensees have agreed to operate under
the terms of the License Agreement until such agreement or agreements are
executed following consummation of the Merger.

     Upon consummation of the Merger, the Company will have the exclusive right
and license of sell the PAPNET-Registered Trademark- System, PAPNET-Registered
Trademark- Service and NSI Technology in the states of Ohio, Georgia, Kentucky,
Missouri, North Carolina and in the Standard Metropolitan Statistical Area of
Chicago, Illinois.

     The License Agreement provides that the regional licensees will be paid
royalties as follows:  (a) monthly royalties equal to 50% of the amount by which
NSI's gross revenues from sales in the licensed territories exceed the cost of
processing slides originating in the licensed territories (for purposes of which
calculation costs per slide may not exceed $1.00 per slide) and the cost of
transporting such slides, with the maximum amount of such monthly royalties in
any fiscal year capped at an amount derived by applying the royalty formula to
12,175,000 slides; (b) annual royalties equal to the difference, if any, by
which aggregate monthly royalties in any fiscal year are less than 4.15% of
NSI's worldwide gross revenues for such fiscal year, with the maximum annual
royalty amount in any fiscal year capped at $23,000,000, less the amount of
monthly royalties paid in such fiscal year calculated as described in clause
(a).  For the purposes of calculating the numbers of slides attributable


                                      -38-
<PAGE>

to the licensed territories which are submitted by certain large laboratories
operating in multiple states ("Multistate National Laboratories"), there will be
attributed to each territory a proportionate number of slides submitted to NSI
for processing from all Multistate National Laboratories equal to the ratio that
the population of such territory bears to the population of the United States
(determined according to official U.S. Census data).

     The royalty calculations described in the foregoing paragraph are 
aggregate calculations for all of the territorial licensees.  Following 
consummation of the Merger, the amounts allocable to the Company will be 
determined according to the population of the geographic areas exclusively 
licensed to the Company. The applicable number of slides for the slide 
royalty cap described in clause (a) in the foregoing paragraph, the worldwide 
revenue percentage described in clause (b) in the foregoing paragraph, and 
the $23,000,000 amount described in the same clause, will be adjusted based 
upon the census data available at the time of the Merger.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 1995 AND 1996

     Royalty revenue for the three months ended March 31, 1996 was $13,553
compared to $10,080 for the same period in 1995.  The increase is a result of
increased worldwide sales at NSI due to NSI receiving FDA approval for the
PAPNET-Registered Trademark- System in November 1995.  While revenue for the
quarters ending March 31, 1996 and 1995 has been accrued using the worldwide
revenue calculation, based on current information management anticipates that
revenue from slide volume from the Company's territory will exceed the revenue
from the worldwide revenue calculation for the 1996 calendar year.

     Slide volume for the quarter ending March 31, 1996 was 1,590 slides
processed compared to 65 slides processed in the quarter ending March 331, 1995.
The increase in slide volume is the result of the FDA approval received in
November 1995 and increasing the number of laboratories offering the
PAPNET-Registered Trademark-  testing.  NSI has spent the first half of 1996
developing a laboratory distribution network for the PAPNET-Registered
Trademark- test so that it would be available for a consumer product launch
sometime during the third quarter of 1996.

     Total operating expense was $149,727 for the three months ended March 31,
1996 compared to $81,601 for the same period the prior year.  The increase is
primarily the result of higher expenses for (i) the addition of sale staff (in
certain territories) and (ii) merger expenses incurred during the three months
ended March 31, 1996.

     Interest income for the three months ended March 31, 1996 was $6,010
compared to $3,766 for the same period the prior year.  The increase was a
result of higher available cash balances to invest.

YEARS ENDED DECEMBER 31, 1993, 1994 AND 1995

     Royalty revenue for the year ended December 31, 1995 was $48,000 compared
to $24,755 for 1994.  the increase is a result of increased worldwide revenue
for NSI as NSI established new marketing operations in Europe, Hong Kong, Canada
and Mexico.  The 1994 royalty revenue was $24,765


                                      -39-
<PAGE>

compared to $4,332 for 1993.  This increase was due to NSI expansion of sales to
European laboratories.

     Total operating expense was $573,149 for the year ended December 31, 1995
compared to $327,361 for 1994.  The increase is primarily the result of higher
expense for (i) the additional sales staff in certain territories in
anticipation of FDA approval of the PAPNET-Registered Trademark- System and (ii)
merger expenses incurred during 1995.  Total operating expense was $327,301 in
1994 compared to $289,913 in 1993.  This increase was primarily the result of
increases in sales and marketing and office expenses as the Company increased
the sales and marketing efforts for the PAPNET-Registered Trademark- System.

     Interest income was $16,606 for the year ended December 31, 1995 compared
to $19,059 for 1994.  Interest income totaled $19,059 for 1994 compared to
$9,037 in 1993.  These fluctuations were due primarily to corresponding
fluctuations in cash and cash equivalents resulting from the issuance of equity
securities in such periods.

     Other income was $1,715,399 for the year ended December 31, 1995.  This
resulted from the exercise of warrants in NSI utilizing a cashless exercise
provision, the settlement of certain claims with NSI from which the Company
received 53,939 shares of NSI stock and the purchase and subsequent sale of
55,000 shares of NSI stock.

LIQUIDITY AND CAPITAL RESOURCES

     The Company has financed its operations primarily by the issuance of equity
securities.  The Company's combined cash and  cash equivalents totaled $599,550
at March 31, 1996, a decrease of $211,808 from December 31, 1995.  The decrease
was primarily the result of (i) funding the first quarter pretax loss of
$131,439 (ii) a decrease in current liabilities of $29,697 and (iii) an increase
in accounts receivable of $53,554.  In addition, the company owns 380,064 shares
of NSI common stock which can be liquidated in an orderly fashion to fund future
operations.  The market value of the NSI shares was $8,286,392 at March 31,
1996.  These shares are currently unrestricted.

     The Company anticipates that its capital requirements will be substantial
for the foreseeable future.  In particular, the Company anticipates that
expenditures will increase significantly in the years 1996 through 1998 due to
the cost of the commercial launch of the Papnet System and the cost of investing
in similar technologies.  The foregoing statements include forward-looking
statements which involve risks and uncertainties.  The Company's actual
experience may differ materially from that discussed above.  Factors that might
cause such a difference include, but are not limited to, those discussed in
"RISK FACTORS" as well as future events that have the effect of reducing the
Company's available cash balances, such as unexpected operating losses or
capital expenditures or cash expenditures related to possible future
acquisitions.

PREDECESSOR COMPANIES

     Each of the Predecessor Companies, except for CCWP, was organized to
acquire and exercise the right to market the PAPNET-Registered Trademark- System
and PAPNET-Registered Trademark- Service within their respective licensed
territories.  However, until November 6, 1995, when the FDA finally approved the
marketing of the PAPNET-Registered Trademark- technology, the technology could
be used in the United States only for investigational


                                      -40-
<PAGE>

purposes in connection with the FDA approval process.  Consequently, the
Predecessor Companies had only minor levels of business activities prior to
November 1995.  Minimal amounts of royalty revenue were earned prior to November
1995 from NSI under license arrangements identical to that described previously
for the Company.   Beginning in late 1995, the Company began managing the
activities of the Predecessor Companies, including the hiring of employees,
pending the completion of the Merger.  In the event the merger is not
consummated, the Predecessor Companies will need to develop their own
infrastructure to market the PAPNET-Registered Trademark- System and
PAPNET-Registered Trademark- Service or engage a third party to do so.

DESCRIPTION OF COMPANY CAPITAL STOCK

     Upon consummation of the Merger, the Company's authorized capital stock
will consist of 15,000,000 shares of Company common stock, without par value,
and 500,000  shares of preferred stock, without par value (the "Company
Preferred Stock").

     The following summary description of the Company's capital stock does not
purport to be complete and is qualified in its entirety by this reference to the
Company's Amended and Restated Articles of Incorporation (the "Company
Articles") and Amended and Restated Regulations (the "Company Regulations"),
copies of which have been filed as exhibits to the Registration Statement of
which this Prospectus forms a part.

     COMPANY COMMON STOCK

     As of March 31, 1996, there were 6,072,936 shares of Company common stock
outstanding and held of record by approximately 400 shareholders.  All of the
issued and outstanding shares of Company common stock are fully paid and
nonassessable.  Holders of validly issued and outstanding shares of Company
common stock are entitled to one vote per share of record on all matters to be
voted upon by shareholders.

     At a meeting of shareholders at which a quorum is present, a majority of
the votes cast decides all questions, unless the matter is one upon which a
different vote is required by express provision of law or the Company Articles
or the Company  Regulations.  There is no cumulative voting with respect to the
election of directors.

     Shareholders have no preemptive or other rights to subscribe for additional
shares nor any other rights to convert their Company common stock into any other
securities.

     Subject to the preferences that may be applicable to the holders of any
outstanding shares of Company Preferred Stock, holders of Company common stock
are entitled to such dividends as may be declared by the Board of Directors out
of funds legally available therefor.  The payment by the Company of dividends,
if any, rests within the discretion of its Board of Directors and will depend
upon the Company's operating results, financial condition and capital
expenditure plans, as well as other factors considered relevant by the Board of
Directors.  The Company may enter into bank credit agreements which include
financial covenants restricting the payment of dividends.  See "SUMMARY - Market
Price Data."


                                      -41-
<PAGE>

     Upon liquidation, dissolution or winding-up of the Company, the assets
legally available for distribution to shareholders are distributable ratably
among the holders of Company common stock at that time outstanding, subject to
prior distribution rights of creditors of the Company and preferential rights of
any outstanding shares of Company Preferred Stock.

     COMPANY PREFERRED STOCK

      Upon effectiveness of the Merger the Company Certificate will authorize
the Board of Directors to issue up to 500,000 shares of Company Preferred Stock
in one or more series and to establish such relative voting, dividend,
redemption, liquidation, conversion and other powers, preferences, rights,
qualifications, limitations and restrictions as the Board of Directors may
determine without further approval of the shareholders of the Company.  The
issuance of  Company Preferred Stock by the  Board of Directors could be used,
under certain circumstances, as a method of delaying or preventing a change in
control of Company and could permit the Company Board of Directors, without any
action by holders of Company common stock, to issue Company Preferred Stock
which could have a detrimental effect on the rights of holders of Company common
stock, including loss of voting control.  In certain circumstances, this could
have the effect of decreasing the market price of the Company common stock.

     The issuance of any series of Company Preferred Stock, and the relative
powers, preferences, rights, qualifications, limitations and restrictions of
such series, if and when established, will depend upon, among other things, the
future capital needs of the  Company, the then-existing market conditions and
other factors that, in the judgment of the Company Board of Directors, might
warrant the issuance of Company Preferred Stock.  At the date of this
Prospectus, there are no plans, agreements or understandings relative to the
issuance of any shares of Company Preferred Stock.

     OHIO LAW AND CERTAIN ARTICLE AND REGULATIONS PROVISIONS

     Certain provisions of the General Corporation Law of Ohio  and of the
Company Articles and the Company Regulations, summarized in the following
paragraphs, may be considered to have an anti-takeover effect and may delay,
deter or prevent a tender offer, proxy contest or other takeover attempt that a
shareholder might consider to be in such shareholder's best interest, including
such an attempt as might result in payment of a premium over the market price
for shares held by shareholders.

     CLASSIFIED BOARD OF DIRECTORS.  The Company Regulations provide for the
Company Board of Directors to be divided into three classes (unless there are
fewer than 9 directors in which case there will be two classes) of directors
serving staggered three-year terms.  As a result, approximately one-third of the
Company Board of Directors will be elected each year.  Classification of the
Company Board of Directors expands the time required to change the composition
of a majority of directors and may tend to discourage a proxy contest or other
takeover bid for the  Company.  The Company Regulations provide that any
director or the entire Company Board of Directors may be removed from office at
any time, but only for cause and only by the affirmative vote of the holders of
at least 80% of all of the outstanding shares of capital stock of the Company
entitled to vote on the election of directors at a meeting of shareholders
called for that purpose, except that if the Company Board of Directors, by an
affirmative vote of at least 66 2/3% of the entire Company Board of Directors,
recommends removal of a director to the shareholders, such removal may be
effected by the affirmative vote of the holders of at least a majority of the
outstanding shares of capital stock of the Company present in person or


                                      -42-
<PAGE>

represented by proxy and entitled to vote on the election of directors at a
meeting of shareholders called for that purpose.  These provisions, when coupled
with provisions of the Company Regulations authorizing only the Company Board of
Directors to fill vacant directorships, will preclude shareholders of the
Company from removing incumbent directors without cause, and simultaneously
gaining control of the Company Board of Directors by filling the vacancies with
their own nominees.

     SPECIAL MEETINGS OF SHAREHOLDERS.  The Company Regulations provide that
special meetings of shareholders may be called by the Chairman of the Board,
President or Chief Executive Officer or by the Board of Directors by action at a
meeting or a majority of the directors without a meeting or by shareholders
holding 50% or more of the  voting power entitled to elect directors.

     ADVANCE NOTICE REQUIREMENTS FOR SHAREHOLDER PROPOSALS AND DIRECTOR
NOMINATIONS.  The Company Regulations provide that shareholders seeking to bring
business before a meeting of shareholders, or to nominate candidates for
election as directors at a meeting of shareholders, must provide timely notice
thereof in writing.  To be timely, a shareholder's notice must be delivered to,
or mailed and received at, the principal executive office of  the Company, not
less than 30 days nor more than 60 days prior to the scheduled meeting (or, if
less than 40 days' notice of the meeting is given to shareholders not later than
the close of business on the tenth day following the earlier of (i) the day on
which such notice of the date of the meeting was mailed, or (ii) the day on
which public disclosure of the date of the special meeting was made).  The
Company Regulations also specify certain requirements pertaining to the form and
substance of a shareholder's notice.  These provisions may preclude some
shareholders from making nominations for directors at an annual or special
meeting or from bringing other matters before the shareholders at a meeting.

     ACTION BY WRITTEN CONSENT OF THE SHAREHOLDERS.  The Ohio General
Corporation Law provides that, unless otherwise provided in the Articles of
Incorporation, any action that is required to be taken at any annual or special
meeting of shareholders, or any action which may be taken at any annual or
special meeting of shareholders, may be taken without a meeting, with the
affirmative vote, or approval, and in a writing signed by all shareholders who
would be entitled to notice of a meeting of the shareholders held for such
purpose.

     DIRECTORS' RESPONSE TO ACQUISITION PROPOSALS.  The Company Articles
provides that the Company Board of Directors must base the response of the
Company to any "Acquisition Proposal" on the Company Board of Directors'
evaluation of what is in the best interest of the Company.  In evaluating what
is in the best interest of  the Company, the Company Board of Directors must
consider all relevant factors including, without limitation, the best interest
of the shareholders which, for this purpose, requires the Company Board of
Directors to consider, among other factors, not only the consideration offered
in the Acquisition Proposal in relation to the then current market price of the
Company's stock, but also in relation to the current value of the Company in a
freely negotiated transaction and in relation to the Company Board of Directors'
then estimate of the future value of the Company as an independent entity or as
the subject of a future Acquisition Proposal; and such other factors as the
Company Board of Directors determines to be relevant, including, among other
factors, the long-term and short-term interests of  the Company and its
subsidiaries and their businesses and properties and the social, legal and
economic effects upon the employees, suppliers, customers, creditors and other
affected persons, firms and corporations and on the communities and geographical
areas in which the Company and its subsidiaries operate or are located.
"Acquisition Proposal" is


                                      -43-
<PAGE>

defined in the Company Articles as any proposal for the consolidation or merger
of the Company with another corporation, any share exchange involving the
Company's outstanding capital stock, any liquidation or dissolution of  the
Company, any transfer of all or a material portion of the assets of  the Company
and any tender offer or exchange offer for any of the Company's outstanding
stock.

     VOTING REQUIREMENTS.  The Company Regulations provide that certain
provisions in the Company Regulations may not be altered, amended or repealed in
any respect, and new provisions inconsistent therewith may not be adopted unless
such action is approved by the affirmative vote of the holders of at least 80%
of all of the outstanding shares of capital stock of the Company entitled to
vote on such matter at a meeting of shareholders called for that purpose.

     DIRECTOR LIABILITY AND INDEMNIFICATION

     The Company Articles provides that the Corporation may indemnify any
director, officer, incorporator or any former director or officer of the
Corporation and any person who is or has served at the request of the
Corporation as a director, officer or trustee of another corporation,
partnership, joint venture, trust or other enterprise (and his or hers heirs,
executors and administrators) against expenses, including attorney fees,
judgments, fines and amounts paid in settlement, actually and reasonably
incurred by him by reason of the fact that he is or was such director, officer,
incorporator or trustee in connection with any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative, or
investigative, to the full extent and according to the procedures and
requirements set forth in the Ohio General Corporation Law as the same may be in
effect from time to time.  The indemnification provided herein shall not be
deemed to restrict the right of the Corporation to (i) indemnify employees,
agents and others as permitted by law, (ii) purchase and maintain insurance or
provide similar protection on behalf of the directors, officers or such other
persons against liabilities asserted against them or expenses incurred by them
arising out of their service to the Corporation as contemplated herein, and
(iii) enter into agreements with such directors, officers, incorporators,
employees, agents or others indemnifying them against any and all liabilities
asserted against them or incurred by them arising out of their service to the
Corporation as contemplated herein.

     (1)  This column represents authorized and outstanding common shares prior
          to the Effective Time of the Merger.  The Company's Articles of
          Incorporation will be amended as described under "THE COMPANY -
          Articles of Incorporation."

     (2)  This column represents authorized and outstanding preferred shares
          prior to the Effective Time of the Merger.

     (3)  INC's Articles of Incorporation provide that if a merger is approved
          by the directors of INC, it can be adopted by a vote of a majority of
          the outstanding shares entitled to vote on the Merger.  Otherwise the
          approval of a merger would require the affirmative vote of two-thirds
          of the outstanding shares entitled to vote the merger.  The Merger has
          been  unanimously recommended by the directors of INC.


     The rights of the shareholders of the Predecessor Companies are currently
governed and defined by the laws of the State of Ohio and by their respective
Articles of Incorporation and or  Regulations.  Upon consummation of the Merger,
the shareholders of the Predecessor Companies will become shareholders of the
Company and their rights will cease to be governed and defined by Articles of
Incorporation and Codes of Regulation and will be defined and governed by the
Ohio General Corporation Law, the Company Articles and the Company  Regulations.
Certain provisions of the Company Articles and the Company  Regulations provide
different rights of shareholders from those that the shareholders of the
Predecessor Companies currently have.  Certain of these provisions are
summarized below.  This summary is not intended to be complete and is qualified
in its entirety by reference to applicable provisions of the Ohio General
Corporation Law and to the respective corporate documents of the Company and the
Predecessor Companies.  For information as to how such corporate documents may
be obtained, see "AVAILABLE INFORMATION."

CAPITAL STOCK

     The Ohio General Corporation Law requires a corporation's Articles of
Incorporation to set forth the total number of shares of all classes of stock
that the corporation has authority to issue, and, for each class, the
designations, powers, preferences, rights, qualifications, limitations and
restrictions thereof.

     The Company Articles currently authorizes 8,000,000 shares of the Company
common stock of which 6,072,936 shares were issued and outstanding on December
31, 1995.  The Company Articles will be amended in connection with the Merger
and will authorize 15,000,000 shares of the Company common stock of which
10,930,449 will be issued and outstanding immediately after the Merger and
500,000 shares of the Company Preferred Stock of which no shares will be
outstanding immediately after the Merger.

     The authorized and issued and outstanding shares of the Predecessor
Companies' capital stock, as of March 31, 1996, is set forth in the Chart.

     The provisions of the Company Articles setting the terms of the Company
common stock are compared in the Chart and differ in certain respects.  Holders
of Company common stock and Predecessor Company common stock, respectively, are
entitled to one vote per share on all matters submitted to a vote of
shareholders.   The Company's shareholders have no preemptive rights, but the
shareholders of ERG and CIN do.  The shareholders of the Company are entitled to
cumulative voting (the Company Articles will be amended to eliminate cumulative
voting) as are the shareholders of the Predecessor Companies.

     The rights, preferences and privileges of holders of Company common stock
are subject to, and may be adversely affected by, the rights of the holders of
shares of any series of Company Preferred Stock that the Company may designate
and issue in the future.  In addition, the right of holders of Company common
stock to receive ratably any dividends that may be declared by the Company Board
of Directors is subject to preferential dividend rights of any Company Preferred
Stock then outstanding.  None of the Predecessor Company Articles of
Incorporation authorize any class of preferred stock.

     Although no shares of the Company Preferred Stock will be outstanding
immediately following the Merger, the Company Board of Directors has the
authority, without any further vote or action by the shareholders, to issue
Company Preferred Stock in one or more classes or series and to fix the number
of shares, designations, powers, preferences, rights, qualifications,
limitations and restrictions thereof.  The ability of the Company Board to so
issue Company Preferred Stock, while providing flexibility in connection with
possible acquisitions and other corporate purposes, could have the effect of
making it more difficult for a third party to acquire (or of discouraging a
third party from acquiring) a majority of the outstanding voting stock of the
corporation.  The Company currently has no plan to issue any Company Preferred
Stock.

VOTING POWER

     Holders of Company common stock and Predecessor Company common stock,
respectively, are entitled to one vote per share.

PAYMENT OF DIVIDENDS AND OTHER DISTRIBUTIONS

     The Ohio General Corporation Law generally allows dividends to be paid in
cash, property, or shares of the corporation.  The dividend shall not exceed the
combination of the surplus of the Corporation and the difference between (i) the
reduction in surplus that results from the immediate recognition of the
transition obligation under the statement of financial accounting standards No.
106; and (2) the aggregate amount of the transition obligation that would have
been recognized as of the date of the declaration of a dividend if the
corporation had elected to amortize its recognition of the transition obligation
under statement of financial accounting standards No. 106.  However, no
dividends may be paid to the holders of shares of any class in violation of the
rights of the holders of shares of any other class, or when the corporation is
solvent or there is reasonable ground to believe that by such payment it would
be rendered insolvent.  Holders of both the Company common stock and the
Predecessor Company common stock are entitled to receive dividends in such
amounts and at such times as declared by their respective Boards of Directors.
Neither the Company nor any Predecessor Company has paid cash dividends.  The
Company presently anticipates that all of its future earnings will be retained
for the development of its business and does not anticipate paying cash
dividends on the Company common stock in the foreseeable future.  The payment of
any future dividends will be at the discretion of the Company's Board of
Directors and will be based on the Company's future earnings, financial
condition, capital requirements and other relevant factors.

REGULATION PROVISIONS

</TABLE>


MEETINGS OF SHAREHOLDERS

The Company Regulations provide that special meetings of shareholders may be
called by the Chairman of the Board, President or Chief Executive Officer, or by
the Board of Directors by action


                                      -50-

<PAGE>

or a majority of the Directors without a meeting or by shareholders holding 80%
or more of the voting power of the then outstanding shares entitled to vote in
an election of Directors.  Except as otherwise provided by law or by the Company
Articles, a quorum for any meeting of the Company shareholders is a majority of
the capital stock issued and outstanding and entitled to vote at the meeting.

SHAREHOLDER NOMINATIONS AND PROPOSALS

     The Company Regulations also specify certain requirements pertaining to the
form and substance of a shareholder's notice.  These provisions may preclude
some shareholders from making nominations for directors at an annual or special
meeting or from bringing other matters before the shareholders at a meeting.
See "COMPANY - Description of Capital Stock."

     Although the Company corporate documents do not give the Company Board any
power to approve or disapprove shareholder nominations for the election of
directors or proposals for action, the foregoing provisions may have the effect
of precluding a contest for the election of directors or the consideration of
shareholder proposals if the proper procedures are not followed, and of
discouraging or deterring a third party from conducting a solicitation of
proxies to elect its own slate of directors or to approve its own proposal,
without regard to whether consideration of such nominees or proposals might be
harmful or beneficial to the Company and its shareholders.  On the other hand,
by requiring advance notice of nominations by shareholders, these shareholder
notice procedures afford the Company Board of Directors an opportunity to
consider the qualifications of the proposed nominees and, to the extent deemed
necessary or desirable by the Company Board of Directors, to inform shareholders
about such qualifications.  By requiring advance notice of other proposed
business, the shareholder notice procedures provide a more orderly procedure for
conducting annual meetings of shareholders and, to the extent deemed necessary
or desirable by the Company Board of Directors, provide the Board with an
opportunity to inform shareholders, prior to such meeting, of any business
proposed to be conducted at the meeting, together with any recommendations by
the Company Board of Directors or statements as to the Company Board of
Director's position regarding action to be taken with respect to such business,
so that shareholders can better decide whether to attend the meeting or to grant
a proxy regarding the disposition of any such business.

AMENDMENT OF ARTICLES OF INCORPORATION AND REGULATIONS

     The Ohio General Corporation Law provides that an amendment to a
corporation's Articles  of Incorporation requires the approval of the Board of
Directors in certain instances and the affirmative vote of the holders of shares
entitling them to exercise two-thirds of the voting power of the corporation in
other instances.

     The Company Articles and the Company Regulations provide that certain
provisions in the Company Articles and the Company Regulations may not be
altered, amended or repealed in any respect, and new provisions inconsistent
therewith may not be adopted unless such action is approved by the affirmative
vote of the holders of at least 80% of all of the outstanding shares of capital
stock of the Company entitled to vote on such matter at a meeting of
shareholders called for that purpose, except that if the Company Board of
Directors, by an affirmative vote of at least 66 2/3% of the entire Company
Board of Directors, recommends approval of such amendment to the Company
Articles to the shareholders, such approval may be effected by the affirmative
vote of the holders of at least a


                                      -51-

<PAGE>


majority of the outstanding shares of capital stock of the Company present in
person or represented by proxy and entitled to vote on such matter at a meeting
of shareholders called for that purpose.  See "COMPANY - Description of Capital
Stock."

ACTION BY WRITTEN CONSENT

     The Ohio General Corporation Law provides that, unless otherwise provided
in the Articles of Incorporation, any action that is required to be taken at any
annual or special meeting of shareholders, or any action which may be taken at
any annual or special meeting of shareholders, may be taken without a meeting,
without prior notice and without a vote, if a consent in writing, setting forth
the action so taken, shall be signed by all the shareholders who would be
entitled to notice of a meeting of the shareholders held for such purpose.  See
"THE COMPANY - Description of Capital Stock."

SIZE AND CLASSIFICATION OF BOARD OF DIRECTORS; REMOVAL OF DIRECTORS; FILLING
VACANCIES

     The Company Regulations provide for the Company Board of Directors to be
divided into three classes (unless there are fewer than 9 directors in which
case there will be two classes) of directors serving staggered two-year terms.
As a result, approximately one-half of the Company Board of Directors will be
elected each year.  Classification of the Company Board of Directors expands the
time required to change the composition of a majority of directors and may tend
to discourage a proxy contest or other takeover bid for the  Company.  The
Company Regulations provide that any director or the entire Company Board of
Directors may be removed from office at any time, but only for cause and only by
the affirmative vote of the holders of at least 80% of all of the outstanding
shares of capital stock of the Company entitled to vote on the election of
directors at a meeting of shareholders called for that purpose, except that if
the Company Board of Directors, by an affirmative vote of at least 66 2/3% of
the entire Company Board of Directors, recommends removal of a director to the
shareholders, such removal may be effected by the affirmative vote of the
holders of at least a majority of the outstanding shares of capital stock of the
Company present in person or represented by proxy and entitled to vote on the
election of directors at a meeting of shareholders called for that purpose.
These provisions, when coupled with provisions of the Company Regulations
authorizing only the Company Board of Directors to fill vacant directorships,
will preclude shareholders of the Company from removing incumbent directors
without cause, and simultaneously gaining control of the Company Board of
Directors by filling the vacancies with their own nominees.  See "THE COMPANY-
Description of Capital Stock."

     Although the Articles of Incorporation of all the Predecessor Companies,
permit cumulative voting, the Company Articles does not.  See COMPARISON OF
CERTAIN RIGHTS OF THE COMPANY AND THE PREDECESSOR COMPANY SHAREHOLDERS - Chart.
Accordingly, with respect to both corporations, holders of a majority of the
shares of common stock entitled to vote in any election of directors of such
corporation may elect all of the directors standing for election.
Classification of the Company directors has the effect of making it more
difficult for shareholders to change the composition of the Company Board of
Directors.  At least two annual meetings of shareholders, instead of one,
generally will be required to effect a change in the majority of a classified
board.  Such a delay may help ensure that incumbent directors, if confronted by
a holder attempting to force a proxy contest, a tender or exchange offer, or any
other extraordinary corporate transaction, would have sufficient time to review
the proposal as well as any available alternatives to the proposal

and to act in what they believe to be the best interests of the shareholders.
See "RISK FACTORS - Anti-Takeover Provisions; Certain Provisions of Ohio Law;
Articles of Incorporation and Regulations."

     The term "cause" is not defined in the Company Articles or the Ohio General
Corporation Law.  Consequently, any question concerning the legal standard for
"cause" would have to be judicially determined and such a determination could be
difficult, expensive and time consuming.

LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS

     Section 1701.59 of the Ohio General Corporation Law provides that a
director shall not be found to have violated his duties under the Ohio General
Corporation Law unless it is proved by clear and convincing evidence that the
director has not acted in good faith, in a manner he reasonably believes to be
in or not opposed to the best interests of the corporation, or with the care
that an ordinary prudent person in a like position would use under similar
circumstances.

     Section 1701.13 of the Ohio General Corporation Law allows for corporations
to indemnify officers and directors from actions, suits or proceedings arising
out of their service to the corporation.  The Company's Articles provide that
the Corporation may indemnify any director, officer, incorporator or any former
director or officer of the Corporation and any person who is or has served at
the request of the Corporation as a director, officer or trustee of another
corporation, partnership, joint venture, trust or other enterprise (and his or
hers heirs, executors and administrators) against expenses, including attorney
fees, judgments, fines and amounts paid in settlement, actually and reasonably
incurred by him by reason of the fact that he is or was such director, officer,
incorporator or trustee in connection with any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative, or
investigative, to the full extent and according to the procedures and
requirements set forth in the Ohio General Corporation Law as the same may be in
effect from time to time.  The indemnification provided herein shall not be
deemed to restrict the right of the Corporation to (i) indemnify employees,
agents and others as permitted by law, (ii) purchase and maintain insurance or
provide similar protection on behalf of the directors, officers or such other
persons against liabilities asserted against them or expenses incurred by them
arising out of their service to the Corporation as contemplated herein, and
(iii) enter into agreements with such directors, officers, incorporators,
employees, agents or others indemnifying them against any and all liabilities
asserted against them or incurred by them arising out of their service to the
Corporation as contemplated herein.

INTERESTED SHAREHOLDER TRANSACTIONS

     Chapter 1704 of the Ohio General Corporation Law prohibits certain
transactions between a Ohio corporation and an "interested shareholder" Chapter
1704 allows for a corporation to exclude itself from Chapter 1204 by exempting
itself in its Articles of Incorporation.  The Company  has not included such an
exemptive provision in the Company Articles.  See "THE COMPANY - Description of
Capital Stock."

PREEMPTIVE RIGHTS

     The Company shareholders do not have preemptive rights to purchase or
subscribe for additional securities of the Company upon any future issuance by
such corporation of such securities.

REPURCHASE AND REDEMPTION OF STOCK

     Ohio corporations may generally purchase or redeem their own shares of
capital stock. The Company Articles provide that its Board of Directors have the
right and power to repurchase any of its outstanding shares upon such terms and
conditions agreed upon by the corporation and the selling shareholder.

                         Report of Independent Auditors


The Board of Directors and Stockholders
Papnet of Ohio, Inc.


We have audited the accompanying balance sheets of Papnet of Ohio, Inc. (the
Company) as of December 31, 1995 and 1994, and the related statements of
operations, stockholders' equity and cash flows for each of the three years in
the period ended December 31, 1995.  These financial statements are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Company at December 31,
1995 and 1994, and the results of its operations and its cash flows for each of
the three years in the period ended December 31, 1995, in conformity with
generally accepted accounting principles.

                          Notes to Financial Statements

                                December 31, 1995



1.  ORGANIZATION AND BASIS OF PRESENTATION

Papnet of Ohio, Inc. (the Company) holds a long-term territorial license
agreement ("License Agreement") issued by Neuromedical Systems, Inc. (NSI),
which provides the right to sell the "PAPNET-Registered Trademark- System" and
the "PAPNET-Registered Trademark- Service", as described below, in Ohio,
Kentucky and the Standard Metropolitan Area of Chicago.

NSI, founded in 1988, is a healthcare technology company focused on diagnostic
screening applications to aid in the early detection of certain cancers.  NSI's
first and to date only product, the PAPNET-Registered Trademark- System, was
approved for commercial use in the United States by the Food and Drug
Administration (the "FDA") on November 8, 1995. The PAPNET-Registered Trademark-
Service permits laboratories to submit slides to one of NSI's central facilities
for processing by the PAPNET-Registered Trademark- System.  NSI's objective is
to establish the use of its PAPNET-Registered Trademark- System as the new
standard of care in cervical cancer screening.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements.
Estimates also affect the reported amounts of revenues and expenses during the
reporting period.  Actual results may differ from these estimates.

CASH EQUIVALENTS

Cash equivalents include investments in highly liquid debt instruments with a
maturity of three months or less at date of acquisition.  The carrying amounts
reported in the balance sheets for cash equivalents approximate fair value.

INVESTMENT IN PARTNERSHIPS

The Company accounts for its minority interest in two partnerships on the equity
method because the Company exercises significant influence over the
partnerships.  The majority owners of these partnerships are parties to the
Merger Agreement described in Note 8.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

FURNITURE AND EQUIPMENT

Furniture and equipment consists of office furniture and computer equipment
recorded at cost which is being depreciated on an accelerated method over
estimated useful lives ranging from five to seven years.

LICENSE AGREEMENT

The License Agreement expires in 2025, but provide for a 20 year renewal option.
Amounts paid by the Company to NSI in exchange for the License Agreement have
been expensed in the years paid.  This accounting reflects the uncertainty as to
the recoverability of amounts paid for the License Agreement, which was
contingent on FDA approval of the PAPNET-Registered Trademark- System and the
ability of NSI and the Company to develop a profitable market for the
technology.  The Company treated these payments as an intangible asset in its
previously issued financial statements.  The Company's historical financial
statements have been restated to conform with the accounting practices of the
other NetMed Entities, as described in Note 8, so there is consistent
application for the merger also described in Note 8.  The effect of this change
on the Company's historical financial statements was to increase income in each
of the three years ended December 31, 1993, 1994 and 1995, by approximately
$43,000, $43,000 and $31,000, respectively, in addition to reducing assets and
retained earnings by the unamortized balance of the intangible asset.

ROYALTY REVENUE

Pursuant to the License Agreements, the Company is entitled to receive a
calculated royalty or a specified percentage of NSI's annual slide processing
revenues less certain expenses, up to specific annual monetary limits for each
licensee.  Royalty revenue is recognized as earned based on the License
Agreements.

INCOME TAXES

The Company accounts for income taxes using the liability method under Statement
of Financial Accounting Standards No. 109 "Accounting for Income Taxes."
Deferred items are determined based on differences between the financial
reporting and tax basis of assets and liabilities, and are measured using the
enacted rates and laws that will be in effect when the differences are expected
to reverse.

STOCK OPTIONS AND WARRANTS

The Company accounts for stock options and warrants under APB 25 "Accounting for
Stock Issued to Employees."

3.  INVESTMENT IN NSI

The Company owns stock in NSI as a result of the exercise of warrants and
settlement of certain claims with NSI.  The investment is classified as
available-for-sale and is carried at fair value, with the unrealized gains and
losses, net of tax, reported as a separate component of stockholders' equity.
NSI trades publicly on the NASDAQ NMS under the symbol "NSIX."  As of December
31, 1995, the Company owned 380,064 shares of NSI stock at a cost of $1,402,002.


The exercise of the warrants in NSI was completed utilizing a cashless exercise
provision in the warrant agreement.  This resulted in a gain of $652,250 which
has been reported as other income.  As a result of settling certain claims with
NSI in December 1995, the Company received 53,939 shares of NSI stock resulting
in a gain of $749,752 which is recorded in other income.  In addition, the
Company was allocated the right to purchase 65,000 shares of NSI stock at NSI's
initial public offering.  The Company purchased and sold the entire 65,000
shares for $1,292,363 during 1995 resulting in a realized gain of $313,397 which
has been recorded as other income.

4.  STOCK OPTIONS AND WARRANTS

The Company adopted a stock option plan in 1995 under which qualified or
nonqualified options may be granted.  No options are currently outstanding under
the Plan.

As of December 31, 1995, there were outstanding 47,020 warrants for the
President of the Company and 24,000 for a former consultant to purchase stock at
exercise prices of $.875 per share and $1.25 per share, respectively.

At December 31, 1995, the Company had unused NOL carryforwards for tax purposes
of approximately $172,000 which expire in 2009.

At December 31, 1993 and 1994, a full valuation allowance was recorded due to
the lack of deferred tax liabilities, historical income and tax planning
strategies.  During 1995, due to the recognition of a significant deferred tax
liability, a valuation allowance was not required.

The reconciliation of income tax computed at the statutory rate to the recorded
tax provision (benefit) is:

                          Notes to Financial Statements

                                December 31, 1995



1.  ORGANIZATION AND BASIS OF PRESENTATION

ER Group, Inc. (the Company) holds a long-term territorial license agreement 
("License Agreement") issued by Neuromedical Systems, Inc. (NSI), which 
provides the right to sell the "PAPNET-Registered Trademark- System" and the 
"PAPNET-Registered Trademark- Service" , as described below, in Georgia.

NSI, founded in 1988, is a healthcare technology company focused on diagnostic
screening applications to aid in the early detection of certain cancers.  NSI's
first and to date only product, the PAPNET-Registered Trademark- System, was
approved for commercial use in the United States by the Food and Drug
Administration (the "FDA") on November 8, 1995.  The PAPNET-Registered
Trademark- Service permits laboratories to submit slides to one of NSI's central
facilities for processing by the PAPNET-Registered Trademark- System.  NSI's
objective is to establish the use of its PAPNET-Registered Trademark- System as
the new standard of care in cervical cancer screening.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements.
Estimates also affect the reported amounts of revenues and expenses during the
reporting period.  Actual results may differ from these estimates.

LICENSE AGREEMENT

The License Agreement expires in 2025, but provides for a 20 year renewal
option.  Amounts paid by the Company to NSI in exchange for the License
Agreement have been expensed in the years paid.  This accounting reflects the
uncertainty as to the recoverability of amounts paid for the License Agreement,
which is contingent on FDA approval of the PAPNET-Registered Trademark- System
and the ability of NSI and the Company to develop a profitable market for the
technology.

                    Notes to Financial Statements (continued)


2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

ROYALTY REVENUE

Pursuant to the License Agreement, the Company is entitled to receive a
calculated royalty or a specified percentage of NSI's annual slide processing
revenues less certain expenses, up to specific annual monetary limits for each
licensee.  Royalty revenue is recognized as earned based on the License
Agreement.

INCOME TAXES

The shareholders of the Company have elected to report the taxable income of the
Company on their individual federal and state income tax returns (Subchapter S
corporation election).  Accordingly, the financial statements include no
provisions for federal or state income taxes.  A deferred tax liability relating
to the gain on investment in NSI stock has been recorded using a 34% rate.  This
liability has been recorded to recognize the obligation that would arise for
distributions to the S Corporation shareholders to pay their tax liabilities
that would arise upon the realization of the gain.

3.  INVESTMENT IN NSI

The Company owns stock in NSI as a result of the exercise of warrants and
settlement of certain claims with NSI.  The investment is classified as
available for sale and is carried at fair value, with the unrealized gains and
losses, net of tax, reported as a separate component of stockholders' equity.
NSI trades publicly on the NASDAQ NMS under the symbol "NSIX."  As of
December 31, 1995, the Company owned 144,363 shares of NSI stock at a cost of
$533,558.

The exercise of the warrants in NSI was completed utilizing a cashless exercise
provision in the warrant agreement.  This resulted in a gain of $247,750 which
has been reported as other income.  As a result of settling certain claims with
NSI in December 1995, the Company received 20,488 shares of NSI stock resulting
in a gain of $285,808 which is recorded in other income.

4.  SUBSEQUENT EVENTS

MERGER AGREEMENT

Certain entities with a degree of common ownership interest also hold long-term
territorial License Agreements for the PAPNET-Registered Trademark- System.
These entities consist of Papnet of Ohio, Inc. ("PPNT"), Cytology Indiana, Inc.
("CIN"), Indiana Cytology Review Corporation ("INC") and Carolina Cytology, Inc.
("CCI").  These entities, along with the Company and CCWP Partners, Inc.
("CCWP"), have signed an agreement to merge into PPNT which will be renamed
NetMed, Inc. (NetMed).  The entities party to the merger are collectively
referred to as the NetMed Entities.

NetMed will hold the License Agreements previously held by the individual NetMed
Entities.  The business purpose of NetMed will be to market the proprietary
products of NSI, including the PAPNET-Registered Trademark- System, in the
territories encompassed under the License Agreements.  These territories include
Ohio, Kentucky, the Standard Metropolitan Area of Chicago, Missouri, Georgia and
North Carolina.

LOAN AGREEMENT WITH PPNT

The Company has entered into a Loan Agreement with PPNT, dated July 5, 1996 (the
"Loan Agreement"), whereby PPNT has agreed to advance to the Company the
expenses incurred in connection with the Merger.  In addition, PPNT will advance
funds necessary to pay reasonable expenses of ordinary business operations for
the Company.  Advances will be evidenced by a promissory note bearing interest
at an annual rate of 7%, payable 60 days after the earlier of the consummation
of the merger or the termination of the Merger Agreement.  Promissory notes
delivered by the Company will be secured by its shares of NSI common stock.
Advances made to the Company may be repaid, at PPNT's option, in shares of the
Company's common stock.

Pending completion of the merger, the business operations of the Company are
being managed by PPNT.

INVESTMENT IN NSI

On July 15, 1996, NSI common stock closed trading on the NASDAQ NMS at $13.25 
per share compared to a closing price of $21.75 at March 31, 1996.

5.  UNAUDITED FINANCIAL STATEMENTS

The financial statements as of March 31, 1996 and for the three months ended 
March 31, 1996 are unaudited; however, in the opinion of management, all 
adjustments (consisting of normal recurring adjustments) necessary for a fair 
presentation of the financial statements for the interim period have been 
included.  The results for the interim period ended March 31, 1996 are not 
necessarily indicative of the results to be obtained for the full fiscal year 
ending December 31, 1996.

Carolina Cytology, Inc. and CCWP Partners, Inc.


We have audited the accompanying combined balance sheet of Carolina Cytology,
Inc. and CCWP Partners, Inc. (the Company) as of December 31, 1995, and the
related combined statements of operations and cash flows for the year then
ended.  These financial statements are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these financial
statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of the Company
at December 31, 1995, and the combined results of their operations and their
cash flows for the year then ended, in conformity with generally accepted

                     Notes to Combined Financial Statements

                                December 31, 1995


1.  ORGANIZATION AND BASIS OF PRESENTATION

Carolina Cytology, Inc. (CCI) holds (through its majority interest in a
partnership) a long-term territorial license agreement ("License Agreement")
issued by Neuromedical Systems, Inc. (NSI), which provides the right to sell the
"PAPNET-Registered Trademark- System" and the "PAPNET-Registered Trademark-
Service", as described below, in North Carolina.  CCWP Partners, Inc. (CCWP) was
formed on December 1, 1995 for the sole purpose of holding an interest in a
partnership that held certain warrants for the purchase of NSI common stock.
These warrants were exercised in December 1995.  The accompanying financial
statements include the accounts of CCI and CCWP and their consolidated
partnerships.  CCI and CCWP are hereinafter referred to collectively as the
"Company".

NSI, founded in 1988, is a healthcare technology company focused on diagnostic
screening applications to aid in the early detection of certain cancers.  NSI's
first and to date only product, the PAPNET-Registered Trademark- System, was
approved for commercial use in the United States by the Food and Drug
Administration (the "FDA") on November 8, 1995.  The PAPNET-Registered
Trademark- Service permits laboratories to submit slides to one of NSI's central
facilities for processing by the PAPNET-Registered Trademark- System.  NSI's
objective is to establish the use of its PAPNET-Registered Trademark- System as
the new standard of care in cervical cancer screening.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements.
Estimates also affect the reported amounts of revenues and expenses during the
reporting period.  Actual results may differ from these estimates.

LICENSE AGREEMENT

The License Agreement expires in 2025, but provide for a 20 year renewal option.
Amounts paid by the Company to NSI in exchange for the License Agreement has
been expensed in the years paid.  This accounting reflects the uncertainty as to
the recoverability of amounts paid for the License Agreement, which is
contingent on FDA approval of the PAPNET-Registered Trademark- System and the
ability of NSI and the Company to develop a profitable market for the
technology.

               Notes to Combined Financial Statements (continued)


2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

ROYALTY REVENUE

Pursuant to the License Agreement, the Company is entitled to receive a
calculated royalty or a specified percentage of NSI's annual slide processing
revenues less certain expenses, up to specific annual monetary limits for each
licensee.  Royalty revenue is recognized as earned based on the License
Agreement.

INCOME TAXES

The shareholders of the Company have elected to report the taxable income of the
Company on their individual federal and state income tax returns (Subchapter S
corporation election).  Accordingly, the financial statements include no
provisions for federal or state income taxes.  A deferred tax liability relating
to the gain on investment in NSI stock has been recorded using a 34% rate.  This
liability has been recorded to recognize the obligation that would arise for
distributions to the S Corporation shareholders to pay their tax liabilities
that would arise upon the realization of the gain.

3.  INVESTMENT IN NSI

The Company owns stock in NSI as a result of the exercise of warrants and
settlement of certain claims with NSI.  The investment is classified as
available-for-sale and is carried at fair value, with the unrealized gains and
losses, net of tax, reported as a separate component of stockholders' equity.
NSI trades publicly on the NASDAQ NMS under the symbol "NSIX."  As of December
31, 1995, the Company owned 144,363 shares of NSI stock at a cost of $533,558.

The exercise of the warrants in NSI was completed utilizing a cashless exercise
provision in the warrant agreement.  This resulted in a gain of $247,750 which
has been reported as other income.  As a result of settling certain claims with
NSI in December 1995, the Company received 20,488 shares of NSI stock resulting
in a gain of $285,808 which is recorded in other income.

4.  SUBSEQUENT EVENTS

MERGER AGREEMENT

Certain entities with a degree of common ownership interest also hold long-term
territorial License Agreements for the PAPNET-Registered Trademark- System.
These entities consist of Papnet of Ohio, Inc. ("PPNT"), Cytology Indiana, Inc.
("CIN"), Indiana Cytology Review Corporation ("INC") and ER Group, Inc. ("ERG").
These entities, along with the Company, have signed an agreement to merge into
PPNT which will be renamed NetMed, Inc. ("NetMed").  The entities party to the
merger are collectively referred to as the NetMed Entities.

NetMed will hold the License Agreements previously held by the individual NetMed
Entities.  The business purpose of NetMed will be to market the proprietary
products of NSI, including the PAPNET-Registered Trademark- System, in the
territories encompassed under the License Agreements.  These territories include
Ohio, Kentucky, the Standard Metropolitan Area of Chicago, Missouri, Georgia and
North Carolina.

LOAN AGREEMENT WITH PPNT

The Company has entered into Loan Agreements with PPNT, dated July 5, 1996 (the
"Loan Agreement"), whereby PPNT has agreed to advance to the Company the
expenses incurred in connection with the Merger.  In addition, PPNT will advance
funds necessary to pay reasonable expenses of ordinary business operations for
the Company.  Advances will be evidenced by a promissory note bearing interest
at an annual rate of 7%, payable 60 days after the earlier of the consummation
of the merger or the termination of the Merger Agreement.  Promissory notes
delivered by the Company will be secured by its shares of NSI common stock.
Advances made to the Company may be repaid, at PPNT's option, in shares of the
Company's common stock.

Pending completion of the merger, the business operations of the Company are
being managed by PPNT.

INVESTMENT IN NSI

On July 15, 1996, NSI common stock closed trading on the NASDAQ NMS at $13.25 
per share compared to a closing price of $21.75 at March 31, 1996.

5.  UNAUDITED FINANCIAL STATEMENTS

The financial statements as of March 31, 1996 and for the three months ended 
March 31, 1996 are unaudited; however, in the opinion of management, all 
adjustments (consisting of normal recurring adjustments) necessary for a fair 
presentation of the financial statements for the interim period have been 
included.  The results for the interim period ended March 31, 1996 are not 
necessarily indicative of the results to be obtained for the full fiscal year 
ending December 31, 1996.

                          Notes to Financial Statements

                                December 31, 1995



1.  ORGANIZATION AND BASIS OF PRESENTATION

Indiana Cytology Review Corporation (the Company) was formed on December 1, 1995
and holds an approximate 35% interest in a long-term territorial license
agreement ("License Agreement") issued by Neuromedical Systems, Inc. (NSI),
which provides the right to sell the "PAPNET-Registered Trademark- System" and
the "PAPNET-Registered Trademark- Service" , as described below, in Missouri.

NSI, founded in 1988, is a healthcare technology company focused on diagnostic
screening applications to aid in the early detection of certain cancers.  NSI's
first and to date only product, the PAPNET-Registered Trademark- System, was
approved for commercial use in the United States by the Food and Drug
Administration (the "FDA") on November 8, 1995.  The PAPNET-Registered
Trademark- Service permits laboratories to submit slides to one of NSI's central
facilities for processing by the PAPNET-Registered Trademark- System.  NSI's
objective is to establish the use of its PAPNET-Registered Trademark- System as
the new standard of care in cervical cancer screening.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements.
Estimates also affect the reported amounts of revenues and expenses during the
reporting period.  Actual results may differ from these estimates.

LICENSE AGREEMENT

The License Agreement expires in 2025, but provides for a 20 year renewal
option.  Amounts paid by the Company to NSI in exchange for the License
Agreement has been expensed in the years paid.  This accounting reflects the
uncertainty as to the recoverability of amounts paid for the License Agreement,
which was contingent on FDA approval of the PAPNET-Registered Trademark- System
and the ability of NSI and the Company to develop a profitable market for the
technology.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

ROYALTY REVENUE

Pursuant to the License Agreement, the Company is entitled to receive a
calculated royalty or a specified percentage of NSI's annual slide processing
revenues less certain expenses, up to specific annual monetary limits for each
licensee.  Royalty revenue is recognized as earned based on the License
Agreement.

INCOME TAXES

The Company, accounts for income taxes using the liability method under
Statement of Financial Accounting Standards No. 109 "Accounting for Income
Taxes."  Deferred items are determined based on differences between the
financial reporting and tax basis of assets and liabilities, and are measured
using the enacted rates and laws that will be in effect when the differences are
expected to reverse.

3.  INVESTMENT IN NSI

The Company owns stock in NSI as a result of the exercise of warrants and
settlement of certain claims with NSI.  The investment is classified as
available-for-sale and is carried at fair value, with the unrealized gains and
losses, net of tax, reported as a separate component of stockholders' equity.
NSI trades publicly on the NASDAQ NMS under the symbol "NSIX."  As of December
31, 1995, the Company owned 25,010 shares of NSI stock at a cost of $92,442.

The exercise of the warrants in NSI was completed utilizing a cashless exercise
provision in the warrant agreement.  This resulted in a gain of $42,924 which
has been reported as other income.  As a result of settling certain claims with
NSI in December 1995, the Company received 3,550 shares of NSI stock resulting
in a gain of $49,518 which is recorded in other income.

territorial License Agreements for the PAPNET-Registered Trademark- System.
These entities consist of Papnet of Ohio, Inc. ("PPNT"), Cytology Indiana, Inc.
("CIN"), ER Group, Inc. ("ERG") and Carolina Cytology, Inc. ("CCI").  These
entities, along with the Company and CCWP Partners, Inc. ("CCWP"), have signed
an agreement to merge into PPNT which will be renamed NetMed, Inc. (NetMed).
The entities party to the merger are collectively referred to as the NetMed
Entities.

NetMed will hold the License Agreements previously held by the individual NetMed
Entities.  The business purpose of NetMed will be to market the proprietary
products of NSI, including the PAPNET-Registered Trademark- System, in the
territories encompassed under the License Agreements.  These territories include
Ohio, Kentucky, the Standard Metropolitan Area of Chicago, Missouri, Georgia and

funds necessary to pay reasonable expenses of ordinary business operations for
the Company.  Advances will be evidenced by a promissory note bearing interest
at an annual rate of 7%, payable 60 days after the earlier of the consummation
of the merger or the termination of the Merger Agreement.  Promissory notes
delivered by the Company will be secured by its shares of NSI common stock.

6.  UNAUDITED FINANCIAL STATEMENTS

The financial statements as of March 31, 1996 and for the three months ended

adjustments (consisting of normal recurring adjustments) necessary for a fair 
presentation of the financial statements for the interim period have been 
included.  The results for the interim period ended March 31, 1996 are not 
necessarily indicative of the results to be obtained for the full fiscal year

                          Notes to Financial Statements

                                December 31, 1995


1.  ORGANIZATION AND BASIS OF PRESENTATION

Cytology Indiana, Inc. (the Company) holds an approximate 65% interest in a
long-term territorial license agreement ("License Agreement") issued by
Neuromedical Systems, Inc. (NSI), which provides the right to sell the
"PAPNET-Registered Trademark- System" and the "PAPNET-Registered Trademark-
Service" , as described below, in Missouri.

NSI, founded in 1988, is a healthcare technology company focused on diagnostic
screening applications to aid in the early detection of certain cancers.  NSI's
first and to date only product, the PAPNET-Registered Trademark- System, was
approved for commercial use in the United States by the Food and Drug
Administration (the "FDA") on November 8, 1995.  The PAPNET-Registered
Trademark- Service permits laboratories to submit slides to one of NSI's central
facilities for processing by the PAPNET-Registered Trademark- System.  NSI's
objective is to establish the use of its PAPNET-Registered Trademark- System as
the new standard of care in cervical cancer screening.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements.
Estimates also affect the reported amounts of revenues and expenses during the
reporting period.  Actual results may differ from these estimates.

LICENSE AGREEMENT

The License Agreement expires in 2025, but provide for a 20 year renewal option.
Amounts paid by the Company to NSI in exchange for the License Agreement have
been expensed in the years paid.  This accounting reflects the uncertainty as to
the recoverability of amounts paid for the License Agreement, which was
contingent on FDA approval of the PAPNET-Registered Trademark- System and the
ability of NSI and the Company to develop a profitable market for the
technology.

               Notes to Financial Statements (continued)




2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

ROYALTY REVENUE

Pursuant to the License Agreement, the Company is entitled to receive a
calculated royalty or a specified percentage of NSI's annual slide processing
revenues less certain expenses, up to specific annual monetary limits for each
licensee.  Royalty revenue is recognized as earned based on the License
Agreements.

INCOME TAXES

The shareholders of the Company have elected to report the taxable income of the
Company on their individual federal and state income tax returns (Subchapter S
corporation election).  Accordingly, the financial statements include no
provisions for federal or state income taxes.  A deferred tax liability relating
to the gain on investment in NSI stock has been recorded using a 34% rate.  This
liability has been recorded to recognize the obligation that would arise for
distributions to the S Corporation shareholders to pay their tax liabilities
that would arise upon the realization of the gain.

3.  INVESTMENT IN NSI

The Company owns stock in NSI as a result of the exercise of warrants and
settlement of certain claims with NSI.  The investment is classified as
available for sale and is carried at fair value, with the unrealized gains and
losses, net of tax, reported as a separate component of stockholders' equity.
NSI trades publicly on the NASDAQ NMS under the symbol "NSIX."  As of December
31, 1995, the Company owned 46,446 shares of NSI stock at a cost of $171,677.

The exercise of the warrants in NSI was completed utilizing a cashless exercise
provision in the warrant agreement.  This resulted in a gain of $79,700 which
has been reported as other income.  As a result of settling certain claims with
NSI in December 1995, the Company received 6,593 shares of NSI stock resulting
in a gain of $91,977 which is recorded in other income.

4.  SUBSEQUENT EVENTS

MERGER AGREEMENT

Certain entities with a degree of common ownership interest also hold long-term
territorial License Agreements for the PAPNET-Registered Trademark- System.
These entities consist of Papnet of Ohio, Inc. ("PPNT"), Indiana Cytology Review
Corporation ("INC"), ER Group, Inc. ("ERG") and Carolina Cytology, Inc. ("CCI").
These entities, along with the Company and CCWP Partners, Inc. ("CCWP"), have
signed an agreement to merge into PPNT, which will be renamed NetMed, Inc.
(NetMed).  The entities party to the merger are collectively referred to as the
NetMed Entities.

NetMed will hold the License Agreements previously held by the individual NetMed
Entities.  The business purpose of NetMed will be to market the proprietary
products of NSI, including the PAPNET-Registered Trademark- System, in the
territories encompassed under the License Agreements.  These territories include
Ohio, Kentucky, the Standard Metropolitan Area of Chicago, Missouri, Georgia and
North Carolina.

LOAN AGREEMENT WITH PPNT

The Company has entered into a Loan Agreement with PPNT, dated July 5, 1996 (the
"Loan Agreement"), whereby PPNT has agreed to advance to the Company the
expenses incurred in connection with the Merger.  In addition, PPNT will advance
funds necessary to pay reasonable expenses of ordinary business operations for
the Company.  Advances will be evidenced by a promissory note bearing interest
at an annual rate of 7%, payable 60 days after the earlier of the consummation
of the merger or the termination of the Merger Agreement.  Promissory notes
delivered by the Company will be secured by its shares of NSI common stock.
Advances made to the Company may be repaid, at PPNT's option, in shares of the
Company's common stock.

Pending completion of the merger, the business operations of the Company are
being managed by PPNT.

INVESTMENT IN NSI

On July 15, 1996, NSI common stock closed trading on the NASDAQ NMS at $13.25 
per share compared to a closing price of $21.75 at March 31, 1996.

5.  UNAUDITED FINANCIAL STATEMENTS

The financial statements as of March 31, 1996 and for the three months ended 
March 31, 1996 are unaudited; however, in the opinion of management, all 
adjustments (consisting of normal recurring adjustments) necessary for a fair 
presentation of the financial statements for the interim period have been 
included.  The results for the interim period ended March 31, 1996 are not 
necessarily indicative of the results to be obtained for the full fiscal year 
ending December 31, 1996.

                     INFORMATION NOT REQUIRED IN PROSPECTUS



ITEM 20.       INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     As permitted by the Ohio General Corporation Law, Article NINTH of 
Registrant's Articles provides that a director, officer, incorporator, or 
any former officer or director of the Registrant shall be indemnified by 
the Registrant to the fullest extent permitted by the Ohio General 
Corporation Law.

     Indemnification of directors, officers, employees and agents is required
under Section 1701.13 of the Ohio General Corporation Law in those cases where
the person to be indemnified has been successful on the merits or otherwise in
defense of a lawsuit.  Indemnification is permitted in third party actions where
the indemnified person acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation and in
criminal actions where he had no reasonable cause to believe his conduct was
unlawful.  Indemnification is also permitted in lawsuits brought by or on behalf
of the corporation if the standards of conduct described above are met, except
that no indemnification is permitted in respect to any matter in which the
person is adjudged to be liable for negligence or misconduct in the performance
of his duty to the corporation unless a court shall determine that
indemnification is fair and reasonable in view of all the circumstances of the
case.  In cases where indemnification is permissive, a determination as to
whether the person met the applicable standard of conduct must be made either by
the court, disinterested directors, by independent legal counsel, or by the
shareholders.  Such indemnification rights are specifically not deemed to be
exclusive of other rights of indemnification by agreement or otherwise and the
corporation is authorized to advance expenses incurred prior to the final
disposition of a matter upon receipt of an undertaking to repay such amounts on
a determination that indemnification was not permitted in the circumstances of
the case.

     Under  Section 1701.13 of the Ohio General Corporation Law, a corporation
may purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee, or agent of the corporation, or who, while serving
in such capacity, is or was at the request of the corporation, a director,
officer, employee or agent of another corporation or legal entity or of an
employee benefit plan, against liability asserted against or incurred by such
person in any such capacity whether or not the corporation would have the power
to provide indemnity under Section 1701.13 of the Ohio General Corporation Law.
The Registrant has not applied for directors' and officers' liability insurance.

     The above discussion of the Registrant's Articles and of Section 1701.13 of
the Ohio General Corporation Law is not intended to be exhaustive and is
respectively qualified in its entirety by such Articles of Incorporation and
statute.

such amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable.  In the event that a claim for


                                      II-3

<PAGE>

indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.

     The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Registration Statement, within one business
day of receipt of such request, and to send the incorporated documents by first
class mail or other equally prompt means.  This includes information contained
in documents filed subsequent to the effective date of the Registration
Statement through the date of responding to the request.

     The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
companies being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.

                                  EXCHANGE OF SHARES

    Section 3.01  EXCHANGE OF CERTIFICATES.

         (a)  At the Effective Time, the Surviving Corporation shall mail to
each holder of record of a certificate or certificates which immediately prior
to the Effective Time represented Predecessor Company Shares (the
"Certificates") a letter of transmittal (which shall specify that delivery shall
be effected, and risk of loss and title to the Certificates shall pass, only
upon delivery of the Certificates to the Surviving Corporation) and instructions
for use in effecting the surrender of the Certificates in exchange for
certificates representing Surviving Corporation Shares.  Upon surrender of a
Certificate to the Surviving Corporation, together with such letter of
transmittal, duly executed, the holder of such Certificate shall be entitled to
receive in exchange therefor the certificates representing the whole Surviving
Corporation Shares which such holder has the right to receive pursuant to the
provisions of this Agreement, and the Certificate so surrendered shall forthwith
be cancelled.  If a certificate representing Surviving Corporation Shares is to
be issued in a name other than that in which the Certificate surrendered in
exchange therefor is registered, it shall be a condition to the issuance that
such Certificate be properly endorsed (or accompanied by an appropriate
instrument of transfer) and accompanied by evidence that any applicable stock
transfer taxes have been paid or provided for.  Until surrendered as
contemplated by this Section, each Certificate shall be deemed at any time after
the Effective Time to represent only the right to receive the consideration
specified herein; provided that in the event any holder of a Certificate
exercises his Dissenter's Rights and becomes entitled to receive payment for his
Predecessor Company Shares instead of the Surviving Corporation Shares into
which such Predecessor Company Shares shall have been converted, the Surviving
Corporation shall pay such holder the amount to which he is entitled for such
Predecessor Company Shares, together with any other sums which it may owe him as
a result of the Dissenter's Rights proceeding, upon his surrender to the
Surviving Corporation of the certificate or certificates which immediately prior
to the Effective Time represented the Predecessor Company Shares as to which his
Dissenter's Rights were asserted, and the Surviving Corporation shall not
thereafter be required to deliver to such holder any Surviving Corporation
Shares.


                                          8
<PAGE>

         Any certificates for Surviving Corporation Shares which remain
unclaimed by the holders of Certificates for twelve months after the Effective
Time shall be held by the Surviving Corporation, and any holders of Certificates
who have not theretofore complied with this Section 3.01(a) shall thereafter
receive delivery (subject to abandoned property, escheat or other similar laws)
of the Surviving Corporation Shares issuable upon the conversion of their
Certificates and any dividends payable on such Surviving Corporation Shares,
without any interest thereon, only after delivering their Certificates and
letters of transmittal to the Surviving Corporation, and otherwise complying
with this Section 3.01(a).

         (b)  No dividends or other distributions declared or made after the
Effective Time with respect to Surviving Corporation Shares with a record date
after the Effective Time shall be paid to the holder of any unsurrendered
Certificate with respect to the Surviving Corporation Shares represented thereby
until the holder of record of such Certificate shall surrender such Certificate.
Following surrender of any such Certificate, there shall be paid to the record
holder of the certificates representing whole Surviving Corporation Shares
issued in exchange therefor, without interest, at the appropriate payment date
(or promptly after surrender if the payment date has already occurred), the
amount of dividends or other distributions with a record date after the
Effective Time but prior to surrender.

         (c)  Following the Effective Time, there shall be no further
registration of transfers on the stock transfer books of any party of
Predecessor Company Shares which were outstanding immediately prior to the
Effective Time.  If, after the Effective Time, Certificates are presented to the
Surviving Corporation for any reason, they shall be cancelled and exchanged as
provided in this Article III.

         (d)  No certificate or scrip representing fractional Surviving
Corporation Shares shall be issued upon the surrender for exchange of
Certificates, such fractional share interests will not entitle the owner thereof
to vote or to any rights of a shareholder of the Surviving Corporation, and no
cash shall be paid in respect of any fractional shares.

    Section 3.02  DISSENTING PREDECESSOR COMPANY SHARES.  If any holder of
Predecessor Company Shares shall exercise Dissenter's Rights with respect to his
Predecessor Company Shares, the affected Predecessor Company shall give the
Surviving Corporation notice thereof and the Surviving Corporation shall have
the right to participate in all negotiations and proceedings with respect to any
such Dissenter's Rights.  No Predecessor Company shall, except with the prior
written consent of the Surviving Corporation, voluntarily make any payment with
respect to, or settle or offer to settle, any such Dissenter's Rights.

    Section 3.03  ADJUSTMENTS.  If, between the date of this Agreement and the
Effective Time, any Company Shares or Predecessor Company Shares shall have been
exchanged into a different number of shares or a different class by reason of
any reclassification, recapitalization, split-up, combination, exchange of
shares or readjustment, or a stock dividend thereon shall be declared with a
record date within such period, the amount of Surviving Corporation Shares into
which any


                                          9
<PAGE>

affected Predecessor Company Shares will be converted in the Merger shall be
correspondingly adjusted.

violation of any applicable law, ordinance, rule, regulation, decree or order of

applicable law.

         (c) With respect to its Predecessor Benefit Plans, in the aggregate,
there are no funded benefit obligations for which contributions have not been

to have a Material Adverse Effect.

present or past operations infringe upon or conflict with the rights of others
with respect to any Intellectual Property necessary to permit it to conduct its
businesses as now operated, and no claim is pending or threatened to the effect
that any of its Predecessor Intellectual Property is invalid or unenforceable.

Predecessor Company in and to its Predecessor Intellectual Property.

    Section 5.01  ORGANIZATION.  It is a corporation duly organized, validly
existing and in good standing under the laws of Ohio and has all requisite power
and authority to own, lease and operate its properties and to carry on its
business as now being conducted.  It is duly qualified or licensed and in good
standing to do business in each jurisdiction in which the property owned, leased
or operated by it or the nature of the business conducted by it makes such
qualification or licensing necessary, except in such jurisdictions where the
failure to be so duly qualified or licensed and in good standing would not in
the aggregate have a Material Adverse Effect.

    Section 5.02  CAPITALIZATION.

          (a)  The authorized capital stock of the Company consists of
8,000,000 shares of common stock, without par value ("Company Shares"), of
which, as of  the date hereof,  6,072,936 are issued and outstanding.  All
issued and outstanding shares of the Company are duly authorized, validly
issued, fully paid and nonassessable and free of preemptive rights.  As of the
date hereof, the number of its shares of any class issuable upon exercise of
Stock Rights and the exercise price(s) thereof are as set forth on Schedule
5.02(a).  All Surviving Corporation Shares which are to be issued pursuant to
the Merger or the other transactions contemplated hereby will be, when issued in
accordance with the respective terms thereof, duly authorized, validly issued,
fully paid and nonassessable and free of any preemptive rights in respect
thereto. Except as set forth in Schedule 5.02(a), since March 31, 1996, the
Company has not issued any shares of its capital stock (nor securities
substantially equivalent to capital stock) except upon exercise of Stock Rights
granted prior to such date.  Except for Company Shares (Surviving Corporation
Shares after the


                                          14
<PAGE>

described in Schedule 5.02(a),  and except as contemplated hereby, there are not
now, and at the Effective Time there will not be, any shares of capital stock
(or securities substantially equivalent to capital stock) of the Company issued
or outstanding or any outstanding Stock Rights.

         (b) Except for common shares of Neuromedical Systems, Inc. and except
as shown on Schedule 5.02(b), the Company does not own, directly or indirectly,
any capital stock or other equity securities of any corporation or have any
direct or indirect equity or ownership interest in any business.  There are not

agreements or understandings to which the Company is a party or is bound with
respect to the voting of the capital stock of the Company.

    Section 5.03  AUTHORITY RELATIVE TO THIS AGREEMENT.  The Company has full
corporate power and authority to execute and deliver this Agreement and to
consummate the transactions contemplated hereby.  The execution and delivery of
this Agreement and the consummation of the transactions contemplated hereby have
been duly and validly authorized by the Board of Directors of the Company and no
other corporate proceedings on the part of the Company are necessary to

Agreement by its shareholders in conformity with the OGCL).  This Agreement has
been duly and validly executed and delivered by the Company and constitutes a
valid and binding agreement of the Company, enforceable against the Company in
accordance with its terms, subject to the Enforceability Exceptions.

    Section 5.04  CONSENTS AND APPROVALS; NO VIOLATIONS.  Except for applicable
requirements of the Securities Act, and the filing and recordation of the
Certificate of Merger as required by the OGCL, no filing with, and no permit,
authorization, consent or approval of, any Governmental Authority is necessary
for the consummation by the Company of the transactions contemplated by this
Agreement.  None of the execution and delivery of this Agreement by the Company,
the consummation by the Company of the transactions contemplated hereby or
compliance by the Company with any of the provisions hereof will (a) conflict
with or result in any breach of any provision of the Articles of Incorporation
or Regulations of the Company, (b) result in a violation or breach of, or
constitute (with or without due notice or lapse of time or both) a default (or
give rise to any right of termination, cancellation or acceleration) under, any
of the terms, conditions or provisions of any Contract to which the Company is a
party or by which it or any of its properties or assets may be bound, or
(c) violate any order, writ, injunction, decree, statute, treaty, rule or
regulation applicable to the Company or any of its properties or assets.

    Section 5.05   FINANCIAL STATEMENTS.  The Company has delivered to each of
the Predecessor Companies copies of its balance sheets as at March 31, 1996 and
December 31 in each of the years 1993 through 1995, and the related statements
of income for each of the three-months' period and fiscal years, respectively,
then ended (the "Company Financial Statements").  All of the Company Financial
Statements fairly present the financial condition and the results of operations
of the Company as at the respective dates thereof and for the periods referred
to therein, all in accordance


                                          15
<PAGE>

with GAAP (except for the absence of notes thereto and statements of changes in
stockholders' equity and cash flow).  The Company Financial Statements reflect
the consistent application of GAAP throughout the periods involved  (except for
the absence of notes thereto and statements of changes in stockholders' equity
and cash flow).

    Section 5.06  ABSENCE OF CERTAIN CHANGES.  Except as set forth in Schedule
5.06, since March 31, 1996, it has not taken any of the actions set forth in
Sections 6.01(b) to (h), suffered any Material Adverse Effect, or entered into
any transaction, or conducted its business or operations, other than in the
ordinary and usual course of business and consistent with past practice.

    Section 5.07  NO UNDISCLOSED LIABILITIES.  At March 31, 1996, the Company
did not have any material liabilities except those reflected in the Company
Financial Statements for the period ending on such date.  Since March 31, 1996,

operations or financial condition, except liabilities incurred in the ordinary
and usual course of business and consistent with past practice and liabilities
incurred in connection with this Agreement and the transactions contemplated
herein.

    Section 5.08  INFORMATION IN REGISTRATION STATEMENT.  None of the
information with respect to the Company referenced in the Registration Statement
will, at the time the Registration Statement is filed with the SEC and at the
time it becomes effective under the Securities Act, contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein not misleading.  Any
Information/Proxy Statement of the Company used in connection with any meeting
of shareholders to be held in connection with the Merger will, at the date
mailed to shareholders and at the time of the meeting of shareholders to be held
in connection with the Merger, not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they are made, not misleading.  The Registration Statement will
comply in all material respects with the provisions of the Securities Act
(including that it will not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make statements therein not misleading), except that no representation is made
by the Company with respect to statements made therein based on information
supplied by any Predecessor Company in writing for inclusion or incorporation by
reference in the Registration Statement.

    Section 5.09  NO DEFAULT.  The Company is not in default or violation (and
no event has occurred which with notice or the lapse of time or both would
constitute a default or violation) of any term, condition or provision of
(a) its Articles of Incorporation or Regulations (b) any Contract to which the
Company is a party or by which it or any of its properties or assets may be
bound or (c) any order, writ, injunction, decree, statute, rule or regulation
applicable to the Company, which defaults or violations would, in the aggregate,
have a Material Adverse Effect or which would prevent or delay the consummation
of the transactions contemplated hereby.

    Section 5.10  LITIGATION.  There is no action, suit, or proceeding pending,
or to the best Knowledge of the Company threatened, involving it, at law or in
equity, or before any Governmental Authority.

    Section 5.11  COMPLIANCE WITH APPLICABLE LAW.  The Company holds all
permits, licenses, variances, exemptions, orders and approvals of all
Governmental Entities necessary for the lawful conduct of its  businesses (the
"Company Permits"), except for failures to hold such Company  Permits which
would not, in the aggregate, have a Material Adverse Effect.  The Company is in
compliance with the terms of the Company Permits, except where the failure so to
comply would not have a Material Adverse Effect.  The businesses of the Company
are not being conducted in violation of any applicable law, ordinance, rule,
regulation, decree or order of any Governmental Authority, except for violations
which in the aggregate do not and would not have a Material Adverse Effect.

    Section 5.12  TAXES.  The Company has duly filed all material federal,
state, local and foreign tax returns required to be filed by it, and it has duly
paid, caused to be paid or made adequate provision for the payment of all Taxes
required to be paid in respect of the periods covered by such returns and has
made adequate provision for payment of all Taxes anticipated to be payable in
respect of all fiscal periods since the periods covered by such returns.  All
deficiencies and assessments asserted as a result of such examinations or other
audits by federal, state, local or foreign taxing authorities have been paid,
fully settled or adequately provided for in the Company Financial Statements,
and no issue or claim has been asserted for Taxes by any taxing authority for
any prior period, other than those heretofore paid or provided for.  There are
no outstanding agreements or waivers extending the statutory period of
limitation applicable to any federal income tax return of the Company.

    Section 5.13  ERISA.

          (a)  With respect to each employee benefit plan (including any
"employee benefit plan", as defined in Section 3(3) of ERISA), and any material
bonus, pension, profit sharing, deferred compensation, incentive compensation,
stock ownership, stock purchase, stock option, phantom stock, retirement,
vacation, severance, disability, death benefit, hospitalization, insurance or
other plan, arrangement or understanding (whether or not legally binding) (all
the foregoing being herein called "Company Benefit Plans"), maintained or
contributed to by it, the Company has made available to the Predecessor
Companies a true and correct copy of, where applicable, (i) the most recent
annual report (Form 5500) filed with the IRS, (ii) such Company Benefit Plan,
(iii) each trust agreement and group annuity contract, if any, relating to such
Company Benefit Plan and (iv) the most recent actuarial report or valuation
relating to a Company Benefit Plan subject to Title IV of ERISA.  None of the
Company Benefit Plans are multiemployer plans within the meaning of
Section 3(37) of ERISA.  Each of the Company Benefit Plans covered by ERISA (i)
has been operated in all material respects in accordance with ERISA, (ii) has
not engaged in any prohibited transactions (as such term is defined in
Section 406 of ERISA) and (iii) has met the minimum funding standards of
Section 412 of the Code.  No material Reportable Event (within the meaning


                                          17
<PAGE>

of Section 4043 of ERISA) has occurred and is continuing with respect to any of
the Company Benefit Plans.  The Company has not terminated any pension plan or
withdrawn from any multiemployer pension plan.

         (b)  With respect to the Company Benefit Plans, in the aggregate, no
event has occurred, and to the Knowledge of the Company there exists no
condition or set of circumstances which are reasonably likely to occur, in
connection with which it would be subject to any liability, that would have a
Material Adverse Effect (except liability for benefits claims and funding
obligations payable in the ordinary course), under ERISA, the Code or any other
applicable law.

         (c) With respect to the Company Benefit Plans, in the aggregate, there
are no funded benefit obligations for which contributions have not been made or
properly accrued and there are no unfunded benefit obligations which have not
been accounted for by reserves, or otherwise properly footnoted in accordance
with GAAP, on its financial statements referenced in Section 5.05, which
obligations are reasonably likely to have a Material Adverse Effect.

    Section 5.14  INTELLECTUAL PROPERTY.  Except as shown on Schedule 5.14, no
claim is pending or, to the Knowledge of the Company is threatened, to the
effect that the present or past operations of the Company infringe upon or
conflict with the rights of others with respect to any Intellectual Property,
and no claim is pending or threatened to the effect that any of the Company
Intellectual Property is invalid or unenforceable.  No Contract with any party
exists which would impede or prevent the continued use by the Surviving
Corporation of the entire right, title and interest of the Company in and to the
Company Intellectual Property.

    Section 5.15  CHANGE IN CONTROL.  The Company is not a party to any
Contract which contains a "change in control" or "potential change in control"

practice.

entering into credit agreements, lines of credit or similar arrangements until
borrowings are made under such arrangements) any indebtedness for borrowed money
or guarantee any such indebtedness or issue or sell any debt securities or
warrants or rights to acquire any debt securities of such party or guarantee (or

ordinary course of business consistent with prior practice.

         (g)  No party shall pay, discharge or satisfy any claims, liabilities
or obligations (absolute, accrued, asserted or unasserted, contingent or
otherwise), other than the payment, discharge or satisfaction in the ordinary
course of business consistent with past practice or in accordance with their
terms, of liabilities reflected or reserved against in, or contemplated by, the

satisfied.

         (j)  Each of the parties shall give prompt notice to the other parties
of: (i) any notice of, or other communication relating to, a default or event
which, with notice or the lapse of time or both, would become a default,
received by it subsequent to the date of this Agreement and prior to the
Effective Time, under any Contract material to its financial condition,
properties, businesses or results of operations; (ii) any notice or other
communication from any third party alleging that the consent of such third party
is or may be required in connection with the transactions contemplated by this
Agreement, which consent, if required, would breach the representations
contained in Articles IV and V; and (iii) any event or circumstance which may
have a Material Adverse Effect.

         (k)  The parties shall consult with each other before issuing any
press releases or otherwise making public statements with respect to the

state governmental or regulatory agency or with any national securities exchange
with respect thereto, and shall also comply with Section 9.09 with respect
thereto.

         (l)  None of the parties hereto or the Surviving Corporation shall at
any time hereafter take or agree to take any action that (without giving effect
to any action taken or agreed to be taken by the other parties hereto or any of
their Affiliates) would prevent the Surviving Corporation from accounting for
the business combination to be effected by the Merger as a reorganization  or a
pooling of interests.

any manner the compensation or fringe benefits of any director, officer or
employee or pay any benefit not required by any plan and arrangement as in
effect as of the date hereof or enter into any Contract to do any of the
foregoing.

    Section 6.08 [Reserved]

    Section 6.09  INDEMNIFICATION AND INSURANCE.  (a)  In the event of any
threatened or actual claim, action, suit, proceeding or investigation, whether
civil, criminal or administrative, including any such claim, action, suit,
proceeding or investigation in which any of the present or former officers or
directors (the "Managers") of the Predecessor Companies is, or is threatened to
be, made a party by reason of the fact that he is or was a director, officer,
employee or agent of a Predecessor Company or an Affiliate thereof, or is or was
serving at the request of a Predecessor Company or an Affiliate thereof as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, whether before or after the Effective Time,
the parties hereto agree to cooperate and use their best efforts to defend
against and respond thereto.  It is understood and agreed that (i) prior to the
Effective Time a Manager's Predecessor Company shall indemnify and hold him
harmless, and from and after the Effective Time the Surviving Corporation shall
indemnify and hold him harmless, as and to the full extent permitted by
applicable law (including by advancing expenses promptly as statements therefor
are received), against any losses, claims, damages, liabilities, costs, expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement in
connection with any claim, action, suit, proceeding or investigation described
in the first sentence of this Section 6.09, and (ii) in the event of any such
claim, action, suit, proceeding or investigation (whether arising before or
after the Effective Time), the Managers may retain counsel satisfactory to them,
and the relevant Predecessor Company prior to the Effective Time, or the
Surviving Corporation after the Effective Time, shall pay all fees and expenses
of such counsel for the Managers promptly, as statements therefor are received,
and will use its respective best efforts to assist in the vigorous defense of
any such matter; provided that no Predecessor Company nor the Surviving
Corporation shall be liable for any settlement effected without its prior
written consent (which consent shall not be unreasonably withheld); and provided
further that no party shall have any obligation hereunder to any Manager when
and if a court of competent jurisdiction shall ultimately determine, and such
determination shall have become final and non-appealable, that indemnification
of such Manager in the manner contemplated hereby is prohibited by applicable
law.  Any Manager wishing to claim indemnification under this Section 6.09(a),
upon learning of any such claim, action, suit, proceeding or investigation,
shall notify the relevant


                                          22
<PAGE>

Predecessor Company and the Company prior to the Effective Time, and after the
Effective Time the Surviving Corporation, thereof (provided that the failure to
give such notice shall not affect any obligations hereunder, unless the
indemnifying party is actually and materially prejudiced thereby).

         (b)  The Company agrees that all rights to indemnification existing in
favor of any Manager as provided in a Predecessor Company's Articles of

         for their Predecessor Company Shares will be the same as the federal
         income tax basis of the Predecessor Company Shares surrendered in
         exchange therefor; and

              (v)  The holding period for the Surviving Corporation Shares

approving the execution and delivery of this Agreement and all other necessary
or proper corporate action to enable it to comply with the terms of this

              (iii)   Such party has taken all required corporate action to
         approve and adopt this Agreement and this Agreement is a valid and
         binding obligation of such party, enforceable in accordance with its
         terms, subject to the Enforceability Exceptions.

         In rendering the foregoing opinion, such counsel may rely on

    Section 8.01  TERMINATION.  This Agreement may be terminated at any time
prior to the Effective Time, whether before or after approval of the matters
presented in connection with the Merger, by the shareholders of the Company or
any or all of the Predecessor Companies:

         (a)  by mutual consent of all of the parties;

         (b)  by any of the parties if the Merger shall not have been
consummated before September 30, 1996 (unless the failure to consummate the
Merger by such date shall be due to the action or failure to act of the party
seeking to terminate this Agreement);


                                          26
<PAGE>

         (c)  by any party if any permanent injunction or other order of a
court or other competent authority preventing the consummation of the Merger
shall have become final and non-appealable;

         (d)  by any party if any required approval of the shareholders of such
party or any other party shall not have been obtained by reason of the failure
to obtain the required vote upon a vote held at a duly held meeting of
shareholders or at any adjournment thereof for the purpose of obtaining such
vote; or

         (e)  by a vote of a majority of the Advisory Board.

    Section 8.02  EFFECT OF TERMINATION.  In the event of the termination and
abandonment of this Agreement pursuant to Section 8.01, this Agreement shall
forthwith become void and have no effect, without any liability on the part of
any party hereto or its Affiliates, directors, officers or shareholders, other
than the provisions of Sections 6.04, 6.12, 8.05 and 9.08.  Nothing contained in
this Section 8.02 shall relieve any party from liability for any breach of this
Agreement.

    Section 8.03  AMENDMENT.  This Agreement may be amended by the parties
hereto, by action taken or authorized by their respective Boards of Directors,
at any time before or after approval of the matters presented in connection with
the Merger by the shareholders of the parties but, after any such approval, no
amendment shall be made which by law requires further approval by such
shareholders without such further approval.  This Agreement may not be amended
except by an instrument in writing signed on behalf of each of the parties
hereto.

    Section 8.04  EXTENSION; WAIVER.  At any time prior to the Effective Time,
the parties hereto may, to the extent legally allowed, (a) extend the time for
the performance of any of the obligations or other acts of the other parties
hereto, (b) waive any inaccuracies in the representations and warranties
contained herein or in any document delivered pursuant hereto and (c) waive

agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in a written instrument signed on behalf of such party.

    Section 8.05  TERMINATION PAYMENT.  In the event that (a) the Merger is not
consummated by reason of a party's breach of this Agreement, or (b) a party
fails to obtain the required approval of the Merger by the shareholders of such
party (in either case, a "Defaulting Party), and this Agreement is thereafter
terminated by any party hereto, in addition to bearing its pro-rata share of
expenses pursuant to Section 9.08 of this Agreement, the Defaulting Party shall
within thirty (30) days of the termination of this Agreement pay to the other
parties the sum of Five Hundred Thousand Dollars ($500,000.00), which shall be
shared among the other parties in proportion to the number of Surviving
Corporation Shares which would have been owned by the shareholders of each such
party immediately after the Effective Time had the Merger been consummated.  The
parties agree that such payment shall constitute liquidated damages, and not a
penalty, and that such


                                          27
<PAGE>

payment shall be in lieu of any money damages suffered by any party by reason of
the Defaulting Party's breach of this Agreement or failure to obtain shareholder
approval.

                    "Non-Voting Preferred Stock").     

          B.   COMMON STOCK

          The holders of the Common Stock are entitled at all times to one vote
          for each share of Common Stock and to such dividends as the Board of
          Directors may in its discretion from time to time legally declare,
          subject, however, to the voting and dividend rights, if any, of the
          holders of the Voting Preferred Stock and the Non-Voting Preferred
          Stock.  In the event of any liquidation, dissolution or winding up of

          the Voting Preferred Stock and the Non-Voting Preferred Stock then
          outstanding.  The Common Stock is subject to all of the terms and
          provisions of the Voting Preferred Stock and the Non-Voting Preferred
          Stock as fixed by the Board of Directors as hereinafter provided.

          each such series, to fix the designation, powers, preferences and
          rights of the shares of each such series and any qualifications,
          limitations or restrictions

                                       -2-

               (g)  the right, if any, of the shares of such series to be
               converted into shares of any other series or class and the terms
               and conditions of such conversion; and

               (h)  any other relative rights, preferences, and limitations of
               that series.

          The holders of Voting Preferred Stock shall be entitled at all times

               converted into shares of any other series or class and the terms
               and conditions of such conversion; and

               (h)  any other relative rights, preferences, and limitations of
               that series.

          Except as otherwise required by law, no holders of Non-Voting
          Preferred Stock shall be entitled to vote on any matter submitted to
          the shareholders of the Corporation.

          
     FIFTH:    The Corporation, through its Board of Directors, shall have the
right and power to repurchase any of its outstanding shares at such times, for
such considerations and upon such terms and conditions as may be agreed upon
between the Corporation and the selling shareholder or shareholders.

     SIXTH:    No holders of shares of the Corporation shall have any pre-
emptive right to subscribe for or to purchase any shares of the Corporation of
any class, whether now or hereafter authorized.
               
     SEVENTH:  The affirmative vote of the holders of the shares entitling 
them to exercise two-thirds of the voting power of the Corporation shall be 
required for the approval or authorization of any (i) merger or consolidation 
or (ii) sale, lease, exchange or other disposition of all or substantially 
all of the assets of the Corporation to or with any other corporation, person 
or other entity; provided, however, that such two-thirds voting requirement 
shall not be applicable if the Board of Directors of the Corporation shall 
have approved such a transaction described in clause (i) or (ii) by 
resolutions adopted by two-thirds of the members of the Board of Directors. 
Except as otherwise expressly provided in this Article Seventh, or elsewhere 
in these Articles, or in the Regulations of the Corporation, and 
notwithstanding any provision of the Ohio Revised Code now

                                      -4-

<PAGE>


or hereafter in force, requiring for any purpose the vote or consent of the 
holders of shares entitling them to exercise two-thirds, or any other 
proportion, of the voting power of the Corporation or of any class or classes 
of shares thereof, such action may be taken by the vote or consent of the 
holders of shares entitling them to exercise a majority of the voting power 
of the Corporation or of such class or classes of shares thereof.     

     EIGHTH:   The Board of Directors shall base the response of the 
Corporation to any "Acquisition Proposal" on the Board of Directors' 
evaluation of what is in the best interest of the Corporation.  In evaluating 
what is in the best interest of the Corporation, the Board of Directors shall 
consider all relevant factors including, without limitation:

          (1)  The best interest of the shareholders which, for this purpose,
     requires the Board of Directors to consider, among other factors, not only
     the consideration offered in the Acquisition Proposal in relation to the
     then current market price of the Corporation's shares, but also in relation
     to the current value of the Corporation in a freely negotiated transaction
     and in relation to the Board of Directors' then estimate of the future
     value of the Corporation as an independent entity or as the subject of a
     future Acquisition Proposal; and

          (2)  Such other factors as the Board of Directors determines to be
     relevant, including, among other factors, the long-term and short-term
     interests of the Corporation and its subsidiaries and their businesses and
     properties and the social, legal, and economic effects upon the employees,
     suppliers, customers, creditors, and other affected persons, firms, and
     corporations and on the communities and geographical areas in which the
     Corporation and its subsidiaries operate or are located.

     "Acquisition Proposal" means any proposal for the consolidation or 
merger of the Corporation with or into another corporation, any share 
exchange involving the Corporation's outstanding capital stock, any 
liquidation or dissolution of the Corporation, any transfer of all or a 
material portion of the assets of the Corporation, and any tender offer or 
exchange offer for any of the Corporation's outstanding capital stock.

     NINTH:    The Corporation shall indemnify any director, officer,
incorporator or any former director or officer of the Corporation and any person
who is or has served at the request of the Corporation as a director, officer or
trustee of another corporation, partnership, joint venture, trust or other
enterprise (and his or her heirs, executors and administrators) against
expenses, including attorney fees, judgments, fines and amounts paid in
settlement, actually and reasonably incurred by him or her by reason of the fact
that he or she is or was such director, officer, incorporator or trustee in
connection with any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative, or investigative, to the full extent
and according to the procedures and requirements set forth in the Ohio General
Corporation Law as the same may be in effect from time to time.  The
indemnification provided herein shall not be deemed to restrict the right of the
Corporation to (i) indemnify employees, agents and others as permitted by law,
(ii) purchase and maintain insurance or provide similar protection on behalf of
the directors, officers or

                                       -5-

<PAGE>

such other persons against liabilities asserted against them or expenses 
incurred by them arising out of their service to the Corporation as 
contemplated herein, and (iii) enter into agreements with such directors, 
officers, incorporators, employees, agents or others indemnifying them 
against any and all liabilities asserted against them or incurred by them 
arising out of their service to the Corporation as contemplated herein.

     TENTH:    No shareholder shall have the right to vote cumulatively in the
election of directors pursuant to and in accordance with Section 1701.69(B)(10)
of the Ohio Revised Code.

     ELEVENTH:     These Articles may be amended by the affirmative vote of the
holders of shares entitling them to exercise a majority of the voting power of
the Corporation on the proposal; provided, however, that the provisions set
forth in Articles Eighth, Ninth, and Tenth, and this Article Eleventh, may not
be altered, repealed or amended in any respect, and any new provisions
inconsistent therewith may not be adopted, unless such action is approved by the
affirmative vote of the holders of at least eighty percent (80%) of the
outstanding shares of capital stock of the Corporation present in person or
represented by proxy and entitled to vote on such matter at a meeting of
shareholders called for that purpose, except that if the Board of Directors, by
an affirmative vote of at least sixty-six and two-thirds percent (66-2/3%) of
the entire Board of Directors, recommends approval of such amendment to these
Articles to the shareholders, such approval may be effected by the affirmative
vote of the holders of at least a majority of the Corporation's outstanding
shares of capital stock of the Corporation present in person or represented by
proxy and entitled to vote on such matter at a meeting of shareholders called
for that purpose.
     
     TWELFTH:  These Amended and Restated Articles of Incorporation take the
place of  and supersede the existing Articles of Incorporation of the
Corporation.

                            Meetings of Shareholders

     Section 1.01.  ANNUAL MEETINGS.  The annual meeting of shareholders of 
the Corporation shall be held at such time and on such business day as the 
Board of Directors may determine each year.  The annual meeting shall be held 
at the principal office of the Corporation or at such other place within or 
without the State of Ohio as the Board of Directors may determine.  The 
directors shall be elected thereat and such other business transacted as may 
properly be brought before the meeting.

     Section 1.02.  SPECIAL MEETINGS.  Special meetings of the shareholders 
of the Corporation may be called at any time by the Chairman of the Board, 
President or Chief Executive Officer or, in cases of such officers' absence 
from the United States, death or disability, any Vice President who is 
authorized in such circumstances to exercise the authority of the President, 
or by the Board of Directors by action at a meeting or by a majority of the 
directors acting without a meeting, or by shareholders holding fifty percent 
(50%) or more of the voting power of the then-outstanding shares entitled to 
vote in an election of directors.  Such meetings may be held within or 
without the State of Ohio at such time and place as may be specified in the 
notice thereof.

     Section 1.03.  NOTICE OF MEETINGS.  Written notice of every annual or 
special meeting of the shareholders of the Corporation stating the time, 
place and purposes thereof shall be given to each shareholder entitled to 
notice as provided by law, not less than seven (7) nor more than ninety (90) 
days before the date of the meeting.  Such notice may be given by or at the 
direction of the Chairman of the Board or Secretary of the Corporation, or 
such other officer as is designated by the Board of Directors, by personal 
delivery or by mail addressed to the shareholder at his last address as it 
appears on the records of the Corporation.  Any shareholder may waive in 
writing notice of any meeting, either before or after the holding of such 
meeting, and, by attending any meeting without protesting the lack of proper 
notice prior to or at the commencement of the meeting, shall be deemed to 
have waived notice thereof.

<PAGE>

     Section 1.04.  PERSONS BECOMING ENTITLED BY OPERATION OF LAW OR 
TRANSFER. Every person who, by operation of law, transfer or any other means 
whatsoever, shall become entitled to any shares, shall be bound by every

and address on the records of the Corporation shall have been duly given to 
the persons from whom he derives his title to such shares.

     Section 1.05.  QUORUM AND ADJOURNMENTS.  Except as may be otherwise 
required by law or by the Articles of Incorporation or these Regulations, the 
holders of a majority of the shares entitled to vote at a meeting, present in 
person or by proxy, shall constitute a quorum; provided that any meeting duly 
called, whether a quorum is present or otherwise, may, by vote of the holders 
of the majority of the shares represented and entitled to vote thereat, 
adjourn from time to time, in which case no further notice of any such 
adjourned meeting need be given.

     Section 1.06.  PRESIDING OFFICER.  The Chairman of the Board, or such 
other member of the Board or officer as is designated by the Board of 
Directors, shall preside over meetings of the shareholders.  The Secretary of 
the Corporation shall act as Secretary of the shareholders' meeting and shall 
record all of the proceedings of such shareholders' meeting provided that, in 
the absence of such officer, the presiding officer shall appoint another 
officer of the Corporation to act as Secretary of the meeting.

     Section 1.07.  SHAREHOLDER PROPOSALS.  At an annual or special meeting 
of shareholders, only such business shall be conducted, and only such 
proposals shall be acted upon, as shall have been properly brought before 
such meeting. To be properly brought before a meeting of shareholders, 
business must be (i) in the case of a special meeting, specified in the 
notice of the special meeting (or any supplement thereto), (ii) properly 
brought before the meeting by or at the direction of the Board of Directors, 
or (iii) otherwise properly brought before the meeting by a shareholder.  For 
business to be properly brought before a meeting of shareholders by a 
shareholder, the shareholder must have given timely notice thereof in writing 
to the Secretary of the Corporation.  To be timely, a shareholder's notice 
must be delivered to or mailed and received at the principal executive 
offices of the Corporation not less than thirty (30) days nor more than sixty 
(60) days prior to the meeting of shareholders; provided, however, that, if 
less than forty (40) days' notice or prior public disclosure of the date of 
the meeting is given or made to the shareholders, notice by the shareholder 
to be timely must be so delivered or received not later than the close of 
business on the tenth day following the  earlier of (i) the day on which such 
notice of the date of the meeting was mailed, or (ii) the day on which such 
public disclosure was made.

               A shareholder's notice to the Secretary shall set forth, as to 
each matter the shareholder proposes to bring before a meeting of 
shareholders, (i) a brief description of the business desired to be brought 
before the meeting and the reasons for conducting such business at the 
meeting, (ii) the name and address, as they appear on the Corporation's 
books, of the shareholder proposing such business and any shareholders known 
by such shareholder to be supporting such proposal, (iii) the class and 
number of shares of the Corporation which are beneficially owned by the 
shareholder on the date of such shareholder's notice and by any other 
shareholders known by

                                       -2-

<PAGE>

such shareholder to be supporting such proposal on the date of such 
shareholder's notice, and (iv) any material interest of the shareholder in 
such proposal.

               Notwithstanding anything in these Regulations to the contrary, 
no business shall be conducted at a meeting of shareholders except in 
accordance with the procedures set forth in this Section 1.07.  The presiding 
officer of the meeting of  shareholders shall, if the facts warrant, 
determine and declare to the meeting that the business was not properly 
brought before the meeting in accordance with the procedures prescribed by 
these Regulations, and if he should so determine, he shall so declare to the 
meeting and any such business not properly brought before the meeting shall 
not be transacted.

     Section 1.08.  CONDUCT OF VOTING.  At all meetings of shareholders, 
unless the voting is conducted by inspectors, the proxies and ballots shall 
be received, and all questions relating to the qualification of voters, the 
validity of proxies and the acceptance or rejection of votes shall be 
decided, by the presiding officer of the meeting.  If demanded by 
shareholders, present in person or by proxy, entitled to cast ten percent 
(10%) in number of votes entitled to be cast, or if ordered by the presiding 
officer of the meeting, the vote upon any election or question shall be taken 
by ballot and, upon like demand or order, the voting shall be conducted by 
two inspectors appointed by the presiding officer, in which event the proxies 
and ballots shall be received, and all questions relating to the 
qualification of voters, the validity of proxies and the acceptance or 
rejection of votes shall be decided, by such inspectors.  Unless so demanded 
or ordered, no vote need be by ballot and voting need not be conducted by 
inspectors.  No candidate for election as a director at a meeting shall serve 
as an inspector.

     Section 1.09.  ACTION WITHOUT A MEETING.  Anything contained in the 
Regulations to the contrary notwithstanding, any action which may be 
authorized or taken at a meeting of the shareholders may be authorized or 
taken without a meeting with the affirmative vote, or approval, and in a 
writing or writings signed by, all of the shareholders who would be entitled 
to notice of a meeting of the shareholders held for such purpose, which 
writings shall be filed with or entered upon the records of the Corporation.

                                   ARTICLE II

                                    Directors

     Section 2.01.  AUTHORITY.  The business and affairs of the Corporation 
shall be managed by and under the direction of the Board of Directors.  The 
Board of Directors may exercise all such authority and powers of the 
Corporation and do all such lawful acts and things as are not by statute or 
these Regulations directed or required to be exercised or done by the 
shareholders.

     Section 2.02.  NUMBER.  The number of directors may be determined by the 
vote of the holders of a majority of the voting power of the shares 
represented at any annual meeting or special meeting called for the purpose 
of electing directors or by resolutions adopted at a meeting of the Board of 
Directors by affirmative vote of a majority of the directors then in office, 
provided that: (i) the number of directors shall in no event be fewer than 
six (6) nor more than fifteen (15); (ii) no decrease in the number of 
directors shall have the effect of shortening the terms of any incumbent 
director and the class of directors to which he is elected; and (iii) no 
action shall be taken (whether through amendment of these Regulations or 
otherwise) to increase the number of directors  provided in these Regulations 
from time to time unless at least sixty-six and two-thirds percent (66-2/3%) 
of the entire Board of Directors shall concur in such action.  

     Section 2.03.  CLASSES AND TERMS OF DIRECTORS.  The directors shall be 
classified in respect of the time for which they severally hold office by 
dividing them into three (3) classes, each class consisting of one-third of 
the whole number of the board of directors with any number not evenly 
divisible by three (3) assigned to such class as the board of directors may 
direct.  At the first election at which directors are divided into three (3) 
classes, the directors of the first class shall be elected for a term of one 
(1) year, the directors of the second class shall be elected for a term of 
two (2) years, and the directors of the third class shall be elected for a 
term of three (3) years.

      If at any time the full authorized board of directors should consist of 
less than nine (9) persons, the directors shall be classified into two (2) 
classes, each class consisting of one-half of the whole number of the board 
of directors, with a number not evenly divisible by two (2) assigned to such 
class as the board of directors may direct.  At the first election at which 
directors are divided into two (2) classes, the directors of the first class 
shall be elected for a term of one (1) year and the directors of the second 
class shall be elected for a term of two (2) years.

          At each annual election thereafter at which directors are elected 
by class, the successors to the directors of the class whose terms expire in 
that year shall be elected to hold office for a term of years equal to the 
number of classes that there are to be, so that the term of office of one 
class of directors expires in each year.  Each director shall serve until his 
successor shall be elected, or until his earlier resignation, removal from 
office or death.

                                       -4-

<PAGE>

     In the event a change in the authorized number of directors causes a 
disparity to exist in the number of persons in the classes of directors, the 
board of directors shall designate the classes to which directors shall be 
elected so as to equalize the classes as nearly as feasible.

     Section 2.04.  NOMINATION.  Only persons who are nominated in accordance 
with the following procedures shall be eligible for election as directors. 
Nominations of persons for election as directors of the Corporation may be 
made at a meeting of shareholders by or at the direction of the directors, by 
any nominating committee or person appointed by the directors, or by any 
shareholder of the Corporation entitled to vote for the election of directors 
at the meeting who complies with the notice procedures set forth in this 
Section 2.04.  Such nominations, other than those made by or at the direction 
of the directors, shall be made pursuant to timely notice in writing to the 
Secretary of the Corporation.  To be timely, a shareholder's notice shall be 
delivered to or mailed and received at the principal executive offices of the 
Corporation not less than thirty (30) days nor more than sixty (60) days 
prior to the meeting; provided, however, that ,in the event that less than 
forty (40) days' notice or prior public disclosure of the date of the meeting 
is given or made to shareholders, notice by the shareholder to be timely must 
be so received not later than the close of business on the tenth day 
following the earlier of the day on which such notice of the date of the 
meeting was mailed or such public disclosure was made.  Such shareholder's 
notice shall set forth (i) as to each person who is not an incumbent director 
whom the shareholder proposes to nominate for election as a director, (a) the 
name, age, business address and residence address of such person; (b) the 
principal occupation or employment of such person; (c) the class and number 
of shares of the Corporation which are beneficially owned by such person; and 
(d) any other information relating to such person that is required to be 
disclosed in solicitations for proxies for election of directors pursuant to

Corporation may require any proposed nominee to furnish such other 
information as may be reasonably required by the Corporation to determine the 
qualifications of such proposed nominee to serve as a director of the 
Corporation.

          The presiding officer of the meeting shall, if the facts warrant, 
determine and declare to the meeting that a nomination was not made in

determine, the defective nomination shall be disregarded.

of the Articles of Incorporation or these Regulations (and notwithstanding the
fact that some lesser percentage may be specified by  the General Corporation
Law of the State of Ohio, the Articles of Incorporation or these Regulations),

or represented by proxy and entitled to vote on the election of directors at 
a meeting of shareholders called for that purpose, except that if the Board 
of Directors, by an affirmative vote of at least sixty-six and two-thirds 
percent (66-2/3%) of the entire Board of Directors, recommends removal of a 
director to the shareholders, such removal may be effected by the affirmative 
vote of the holders of at least a majority of the outstanding shares of 
capital stock of the Corporation present in person or represented by proxy 
and entitled to vote on the election of directors at a meeting of 
shareholders called for that purpose.

directors so chosen shall hold office for a term expiring at the annual 
meeting of shareholders at which the term of the class to which they have 
been elected expires and until their successors are duly elected and 
qualified.  If there are no directors in office, then an election of 
directors may be held in the manner provided by the General Corporation Law 
of the State of Ohio.

     Section 2.07.  QUORUM AND ADJOURNMENT.  A majority of the directors in 
office at the time shall constitute a quorum, provided that any meeting duly 
called, whether a quorum is present or otherwise, may, by vote of a majority 
of the directors present, be adjourned.  At any meeting at which a quorum is 
present, all questions and business shall be determined by the affirmative 
vote of not less than a majority of the directors present, except as 
otherwise provided in the Articles of Incorporation or these Regulations or 
as otherwise authorized by law.  Any action required or permitted to be taken 
at a meeting of the Board of Directors may be taken without a meeting if a 
unanimous written consent which sets forth the action is signed by each 
member of the Board of Directors and filed with the minutes of the 
proceedings of the Board of Directors.

     Section 2.08.  REGULAR MEETINGS.  After each annual meeting of 
shareholders at which directors shall have been elected, the Board of 
Directors shall meet as soon as practicable for the purpose of organization 
and the transaction of other business.  Such first regular meeting shall be 
held at any place as may be designated by the Chairman of the Board or by 
action of the Board of Directors, or in default of such designation at the 
place of the holding of the immediately preceding meeting of shareholders.  
Any other regular meeting of the Board of Directors shall be held on such 
date and at any place as may be designated from time to time by the Chairman 
of the Board or by action of the Board of Directors.  No notice of such 
regular meetings shall be necessary if held as hereinabove provided.

Chairman of the Board, President, or Chief Executive Officer or, in the case 
of such officers' absence from the United States, death or disability, such 
other officer who is authorized in such circumstances to exercise the 
authority of the President, or by action of the Board of Directors or any 
three (3) members thereof.

it is delivered personally to him, left at his residence or usual place of

that notice of a special meeting which is called by the Chairman of the 
Board, President or Chief Executive Officer is given to a director when it is 
delivered personally to him or sent by telegraph or telephone at least 
twenty-four (24) hours before the time of the meeting.  Unless these 
Regulations or a resolution of the Board of Directors provides otherwise, the 
notice need not state the business to be transacted at or the purposes of any 
regular or special meeting of the Board of Directors.  No notice of any 
meeting of the Board of Directors need be given to any director who attends, 
or to any director who, in a writing executed and filed with the records of 
the meeting either before or after the holding thereof, waives such notice.  
Any regular or special meeting of the Board of Directors may be adjourned 
from time to time and be reconvened at the same or some other place and no 
notice need be given of any such adjourned meeting.

     Section 2.11.  MEETING BY CONFERENCE TELEPHONE.  Members of the Board of 
Directors may participate in a meeting by means of a conference telephone or 
similar communications equipment if all persons participating in the meeting 
can hear each other at the same time.  Participation in a meeting by these 
means constitutes presence in person at a meeting.

     Section 2.12.  COMPENSATION.  The Board of Directors shall have the 
authority to fix the compensation of the directors.  The directors may be 
paid their expenses, if any, of attendance at each regular and special

resolution of the Board of Directors, a stated annual retainer and/or a fixed 
sum for attendance at each regular or special meeting of the Board of 
Directors or committees thereof, and other compensation for their services as 
such, may be paid to directors.  A director who serves the Corporation in any 
other capacity also may receive compensation for such other services if 
approved by the Board of Directors.

     Section 3.02.  COMMITTEE PROCEDURE.  The Board of Directors shall have 
the power to prescribe the manner in which proceedings of each committee 
shall be held.  Unless the Board of Directors shall otherwise provide, the 
actions of each committee shall be governed by the following rules of 
procedure.  A majority of the members of a committee shall constitute a 
quorum for the transaction of business and the act of a majority of those 
present at a meeting at which a quorum is present shall be the act of the 
committee.  The members of a committee present at any meeting, whether or not 
they constitute a quorum, may appoint a director to act in the place of an 
absent member.  Any action required or permitted to be taken at a meeting of 
a committee may be taken without a meeting, if a unanimous written consent 
which sets forth the action is signed by each member of the committee and 
filed with the minutes of the committee.  The members of a committee may 
conduct any meeting thereof by conference telephone or similar communications 
equipment if all persons participating in the meeting can hear each other at 
the same time.  Participation in a meeting by these means constitutes 
presence in person at a meeting.  In the absence of any prescription by the 
Board of Directors or any applicable provision of these Regulations, each 
committee may prescribe the manner in which its proceedings shall be 
conducted.

acting shall have the powers of the President.  If there be more than one 
Vice President, the Board of Directors may determine which one or more of the

bond sufficient to indemnify the Corporation and any transfer agent and/or 
registrar against any claim that may be made against it or them on account of

to place the word "Seal" adjacent to the signature of the person authorized 
to sign the document on behalf of the Corporation.

     Section 7.03.  VOTING UPON SHARES IN OTHER CORPORATIONS. Stock of other

                                   (the "Office") re-examination of the
                                   patents which relate to the System.  On
                                   May 2, 1995, the Office granted a request
                                   to re-examine three of the four patents
                                   relating to the System.  The Office is
                                   relying on a third party's claim that
                                   prior patents and printed publications
                                   raise substantial new questions of
                                   patentability.  Office actions dealing
                                   with two of the three patents have been
                                   received.  For one patent, a number of
                                   claims were confirmed patentable and
                                   other claims were initially rejected. 
                                   With respect to the other patent, all
                                   claims were initially rejected.  There
                                   has been no action to date on the third
                                   patent.  There is no certainty as to the
                                   ultimate outcome of any re-examination by
                                   the Office.

                                NATURE OF CLAIMS 

     As a licensee for the Papnet Testing System (the "System"), the Company 
is subject to the United States Patent and Trademark Office (the "Office") 
re-examination of the patents which relate to the System.  On May 2, 1995, 
the Office granted a request to re-examine three of the four patents relating 
to the System.  The Office is relying on a third party's claim that prior 
patents and printed publications raise substantial new questions of 
patentability.  Office actions dealing with two of the three patents have 
been received.  For one patent, a number of claims were confirmed patentable 
and other claims were initially rejected.  With respect to the other patent, 
all claims were initially rejected.  There has been no action to date on the 
third patent.  There is no certainty as to the ultimate outcome of any 
re-examination by the Office. 

     The FDA recently warned the Company that certain promotional materials 
relating to the PAPNET-Registered Trademark-System appearing on the 
Company's World Wide Web site failed to comply with certain FDA premarket 
approval regulations.  The FDA cited specific claims made in these materials 
and advised the Company that it should review these and other promotional 
materials to ensure compliance with the regulations.  While the Company 
believes that the materials comply in all respects with applicable 
regulations, it has suspended access to these materials on its Web site 
pending FDA's evaluation of its detailed response to the warning letter.

               SECTION 1701.85 OF THE OHIO GENERAL CORPORATION LAW

     @ 1701.85 QUALIFICATION AND PROCEDURES FOR DISSENTING SHAREHOLDERS 

   (A)(1) A shareholder of a domestic corporation is entitled to relief as a 
dissenting shareholder in respect of the proposals described in sections 
1701.74, 1701.76, and 1701.84 of the Revised Code, only in compliance with 
this section. 

   (2) If the proposal must be submitted to the shareholders of the 
corporation involved, the dissenting shareholder shall be a record holder of 
the shares of the corporation as to which he seeks relief as of the date 
fixed for the determination of shareholders entitled to notice of a meeting 
of the shareholders at which the proposal is to be submitted, and such shares 
shall not have been voted in favor of the proposal. Not later than ten days 
after the date on which the vote on the proposal was taken at the meeting of 
the shareholders, the dissenting shareholder shall deliver to the corporation 
a written demand for payment to him of the fair cash value of the shares as 
to which he seeks relief, which demand shall state his address, the number 
and class of such shares, and the amount claimed by him as the fair cash 
value of the shares. 

   (3) The dissenting shareholder entitled to relief under division (C) of 
section 1701.84 of the Revised Code in the case of a merger pursuant to 
section 1701.80 of the Revised Code and a dissenting shareholder entitled to 
relief under division (E) of section 1701.84 of the Revised Code in the case 
of a merger pursuant to section 1701.801 [1701.80.1] of the Revised Code 
shall be a record holder of the shares of the corporation as to which he 
seeks relief as of the date on which the agreement of merger was adopted by 
the directors of that corporation. Within twenty days after he has been sent 
the notice provided in section 1701.80 or 1701.801 [1701.80.1] of the Revised 
Code, the dissenting shareholder shall deliver to the corporation a written 
demand for payment with the same information as that provided for in division 
(A)(2) of this section. 

   (4) In the case of a merger or consolidation, a demand served on the 
constituent corporation involved constitutes service on the surviving or the 
new entity, whether the demand is served before, on, or after the effective 
date of the merger or consolidation. 

   (5) If the corporation sends to the dissenting shareholder, at the address
specified in his demand, a request for the certificates representing the shares
as to which he seeks relief, the dissenting shareholder, within fifteen days
from the date of the sending of such request, shall deliver to the corporation
the certificates requested so that the corporation may forthwith endorse on them
a legend to the effect that demand for the fair cash value of such shares has
been made. The corporation promptly shall return such endorsed certificates to
the dissenting shareholder. A dissenting shareholder's failure to deliver such
certificates terminates his rights as a dissenting shareholder, at the option of
the corporation, exercised by written notice sent to the dissenting

                                     B-1

<PAGE>

shareholder within twenty days after the lapse of the fifteen-day period, 
unless a court for good cause shown otherwise directs. If shares represented 
by a certificate on which such a legend has been endorsed are transferred, 
each new certificate issued for them shall bear a similar legend, together 
with the name of the original dissenting holder of such shares. Upon 
receiving a demand for payment from a dissenting shareholder who is the 
record holder of uncertificated securities, the corporation shall make an 
appropriate notation of the demand for payment in its shareholder records. If 
uncertificated shares for which payment has been demanded are to be 
transferred, any new certificate issued for the shares shall bear the legend 
required for certificated securities as provided in this paragraph. A 
transferee of the shares so endorsed, or of uncertificated securities where 
such notation has been made, acquires only such rights in the corporation as 
the original dissenting holder of such shares had immediately after the 
service of a demand for payment of the fair cash value of the shares. A 
request under this paragraph by the corporation is not an admission by the 
corporation that the shareholder is entitled to relief under this section. 

   (B) Unless the corporation and the dissenting shareholder have come to an 
agreement on the fair cash value per share of the shares as to which the 
dissenting shareholder seeks relief, the dissenting shareholder or the 
corporation, which in case of a merger or consolidation may be the surviving 
or new entity, within three months after the service of the demand by the 
dissenting shareholder, may file a complaint in the court of common pleas of 
the county in which the principal office of the corporation that issued the 
shares is located or was located when the proposal was adopted by the 
shareholders of the corporation, or, if the proposal was not required to be 
submitted to the shareholders, was approved by the directors. Other 
dissenting shareholders, within that three-month period, may join as 
plaintiffs or may be joined as defendants in any such proceeding, and any two 
or more such proceedings may be consolidated. The complaint shall contain a 
brief statement of the facts, including the vote and the facts entitling the 
dissenting shareholder to the relief demanded. No answer to such a complaint 
is required. Upon the filing of such a complaint, the court, on motion of the 
petitioner, shall enter an order fixing a date for a hearing on the complaint 
and requiring that a copy of the complaint and a notice of the filing and of 
the date for hearing be given to the respondent or defendant in the manner in 
which summons is required to be served or substituted service is required to 
be made in other cases. On the day fixed for the hearing on the complaint or 
any adjournment of it, the court shall determine from the complaint and from 
such evidence as is submitted by either party whether the dissenting 
shareholder is entitled to be paid the fair cash value of any shares and, if 
so, the number and class of such shares. If the court finds that the 
dissenting shareholder is so entitled, the court may appoint one or more 
persons as appraisers to receive evidence and to recommend a decision on the 
amount of the fair cash value. The appraisers have such power and authority 
as is specified in the order of their appointment. The court thereupon shall 
make a finding as to the fair cash value of a share and shall render judgment 
against the corporation for the payment of it, with interest at such rate and 
from such date as the court considers equitable. The costs of the proceeding, 
including reasonable compensation to the appraisers to be fixed by the court, 
shall be assessed or apportioned as the court considers equitable. The 
proceeding is a special proceeding and final orders in it may be vacated, 
modified, or reversed on appeal

                                     B-2

<PAGE>

pursuant to the Rules of Appellate Procedure and, to the extent not in 
conflict with those rules, Chapter 2505. of the Revised Code. If, during the 
pendency of any proceeding instituted under this section, a suit or 
proceeding is or has been instituted to enjoin or otherwise to prevent the 
carrying out of the action as to which the shareholder has dissented, the 
proceeding instituted under this section shall be stayed until the final 
determination of the other suit or proceeding. Unless any provision in 
division (D) of this section is applicable, the fair cash value of the shares 
that is agreed upon by the parties or fixed under this section shall be paid 
within thirty days after the date of final determination of such value under 
this division, the effective date of the amendment to the articles, or the 
consummation of the other action involved, whichever occurs last. Upon the 
occurrence of the last such event, payment shall be made immediately to a 
holder of uncertificated securities entitled to such payment. In the case of 
holders of shares represented by certificates, payment shall be made only 
upon and simultaneously with the surrender to the corporation of the 
certificates representing the shares for which the payment is made. 

   (C) If the proposal was required to be submitted to the shareholders of 
the corporation, fair cash value as to those shareholders shall be determined 
as of the day prior to the day on which the vote by the shareholders was 
taken and, in the case of a merger pursuant to section 1701.80 or 1701.801 
[1701.80.1] of the Revised Code, fair cash value as to shareholders of a 
constituent subsidiary corporation shall be determined as of the day before 
the adoption of the agreement of merger by the directors of the particular 
subsidiary corporation. The fair cash value of a share for the purposes of 
this section is the amount that a willing seller who is under no compulsion 
to sell would be willing to accept and that a willing buyer who is under no 
compulsion to purchase would be willing to pay, but in no event shall the 
fair cash value of a share exceed the amount specified in the demand of the 
particular shareholder. In computing such fair cash value, any appreciation 
or depreciation in market value resulting from the proposal submitted to the 
directors or to the shareholders shall be excluded. 

   (D)(1) The right and obligation of a dissenting shareholder to receive 
such fair cash value and to sell such shares as to which he seeks relief, and 
the right and obligation of the corporation to purchase such shares and to 
pay the fair cash value of them terminates if any of the following applies: 

     (a) The dissenting shareholder has not complied with this section, 
unless the corporation by its directors waives such failure; 

     (b) The corporation abandons the action involved or is finally enjoined 
or prevented from carrying it out, or the shareholders rescind their adoption 
of the action involved; 

     (c) The dissenting shareholder withdraws his demand, with the consent of 
the corporation by its directors; 

                                     B-3

<PAGE>

     (d) The corporation and the dissenting shareholder have not come to an 
agreement as to the fair cash value per share, and neither the shareholder 
nor the corporation has filed or joined in a complaint under division (B) of 
this section within the period provided in that division. 

     (2) For purposes of division (D)(1) of this section, if the merger or 
consolidation has become effective and the surviving or new entity is not a 
corporation, action required to be taken by the directors of the corporation 
shall be taken by the general partners of a surviving or new partnership or 
the comparable representatives of any other surviving or new entity. 

   (E) From the time of the dissenting shareholder's giving of the demand 
until either the termination of the rights and obligations arising from it or 
the purchase of the shares by the corporation, all other rights accruing from 
such shares, including voting and dividend or distribution rights, are 
suspended. If during the suspension, any dividend or distribution is paid in 
money upon shares of such class or any dividend, distribution, or interest is 
paid in money upon any securities issued in extinguishment of or in 
substitution for such shares, an amount equal to the dividend, distribution, 
or interest which, except for the suspension, would have been payable upon 
such shares or securities, shall be paid to the holder of record as a credit 
upon the fair cash value of the shares. If the right to receive fair cash 
value is terminated other than by the purchase of the shares by the 
corporation, all rights of the holder shall be restored and all distributions 
which, except for the suspension, would have been made shall be made to the 
holder of record of the shares at the time of termination.

                                       OF
                              PAPNET OF OHIO, INC.

     The undersigned, a citizen of the United States, desiring to form a 
corporation, for profit, under Sections 1701.01 et seq. of the Revised Code 
of Ohio, does hereby certify:

     FIRST:  NAME.  The name of the corporation shall be PAPNET OF OHIO, INC.

     SECOND:  PRINCIPAL OFFICE.  The place in Ohio where its, principal 
office is to be located is 6472 Moors Place West, Dublin, Franklin County, 
Ohio, 43226.

     THIRD:  PURPOSE.  The purpose for which it is formed is to engage in any 
lawful act or activity for which corporations may be formed under Sections 
1701.01 to 1701.98, inclusive, of the Ohio Revised Code.

     FOURTH:  Shares. The maximum number of shares which the corporation is 
authorized to have outstanding is nine hundred (900) shares, all of which 
shall be common shares without par value.

     FIFTH:  REPURCHASE OF SHARES.  The corporation, through its Board of 
Directors, shall have the right and power to repurchase any of its 
outstanding shares at such price and upon such terms as may be agreed upon 
between the corporation and the selling shareholder or shareholders.

     SIXTH:  CONFLICT OF INTEREST.  A director or officer of the corporation 
shall not be disqualified by his office from dealing or contracting with the 
corporation as a vendor, purchaser, employee, agent or otherwise; nor shall 
any transaction, contract or act of the corporation be void or voidable or in 
any way affected or invalidated by reason of the fact that any director or 
officer or any firm of which of which such director or officer is a 
shareholder, director or officer, is in any way interested in such 
transaction, contract or act, provided the fact that such director, officer, 
firm or corporation

<PAGE>

is so interested shall be disclosed or shall be known to the Board of 
Directors or such members thereof as shall be present at any meeting of the 
Board of Directors, at which action upon any such contract, transaction or 
act shall be taken; nor shall any such director or officer be accountable or 
responsible to the corporation for or in respect of any such transaction, 
contract or act of the corporation, or for any gains or profits realized him 
by reason of the fact that he or any firm of which he is a member, or any 
corporation of which he is a shareholder, officer or director, is interested 
in such transaction, contract or act and any such director or officer, if 
such officer is a director, may be counted in determining the existence of a 
quorum at any meeting of the Board of Directors of the corporation which 
shall authorize or take action in respect of any such contract, transaction 
or act and may vote thereat to authorize, ratify or approve any such 
contract, transaction or act, with like force and effect as if he or any firm 
of which he is a member, or any corporation of which he is a shareholder, 
officer or director, were not interested in such transaction, contract or act.

     SEVENTH:  INDEMNIFICATION.  Every person who is director, officer, or 
employee of the corporation or a former director, officer or employee of the 
corporation, or a person who is serving or has served at the request of the 
corporation as a director, officer or employee of another corporation is 
hereby indemnified against expenses, judgments, decrees, fines, penalties or 
amounts paid in settlement in connection with the defense of any pending or 
threatened action, suit, or proceeding, criminal or civil, to which he is or 
may be made a party by reason of being or having been such director, officer 
or employee, provided he is determined by the directors of the corporation 
acting at a meeting at which a quorum consisting of directors who are not 
parties to or threatened with any such action, suit or proceeding is present 
(a) not to have been negligent or guilty of misconduct in the performance of 
his duty to the corporation of which he is such director, officer or

                                     2

<PAGE>

employee; (b) to have acted in good faith in what he reasonably believed to 
be the best interest of such corporation; and (c) in any matter the subject 
of a criminal action, suit, or proceeding, to have had no reasonable cause to 
believe that his conduct was unlawful; provided, however, no director who is 
a party to or threatened with any such action, suit or proceeding shall be 
qualified to vote on such matter. Alternatively such determinations may be 
made (a) by a court of competent jurisdiction, (b) by the shareholders of the 
corporation at a meeting held for such purpose by the affirmative vote of the 
holders of shares entitling them to exercise a majority of voting power of 
the corporation on such proposal or (c) adopted by the shareholders of the 
corporation without a meeting by the written consent of the holders of share 
entitling them to exercise two-thirds of the voting power on such proposal.

     Such indemnification shall not be deemed exclusive of any other rights 
to which such director, officer or employee may be entitled including, 
without limiting the generality of the foregoing, any insurance purchased by 
the corporation.

     EIGHTH:  STATED CAPITAL.  The amount of stated capital with which the 
corporation shall begin business is not less than Five Hundred Dollars 
($500.00).

     IN WITNESS WHEREOF, I have hereunto subscribed my name this 25th day of 
October, 1989.

                                   /s/ David J. Richards

                  (a)  RIGHT AND INDEMNIFICATION.  Each Director, officer and
member of a committee of this corporation, and any person who may have served at
the request of this corporation as a Director, officer or member of a committee
of any other corporation in which this corporation is a creditor, his heirs,
executors and administrators, shall be indemnified by the corporation against
all costs and expenses reasonably incurred by him concerning, or in connection
with, the defense of any claim asserted or suit or proceeding brought against
him by reason of his conduct or actions as a Director, officer or member of a
committee of this corporation, or a Director, officer or member of a committee
of such other corporation, whether or not he continues to be a Director, officer
or member of a committee at the time of incurring such costs or expenses, except
costs and expenses



                                      12
<PAGE>

incurred in relation to matters as to which such Director, officer or member 
of a committee shall have been willfully derelict in the performance of his 
duty as such Director, officer or member of a committee. Such costs and 
expenses shall include the costs of reasonable settlements (with or without 
suit), judgments, attorneys' fees, costs of suit, fines and penalties and 
other liabilities (other than amounts paid by any such person to this 
corporation or any such other corporation).

                  (b)  DEFINITION OF PERFORMANCE.  For the purposes of this
Article, a Director, officer or member of a committee shall conclusively be
deemed not to have been willfully derelict in the performance of his duty as
such Director, officer or member of a committee:

                       (1) DETERMINATION BY SUIT.  In a matter which shall have
been the subject of a suit or proceeding in which he was a party which is
disposed of by adjudication on the merits, unless he shall have been finally
adjudged in such suit or proceeding to have been willfully derelict in the
performance of his duty as such Director, officer or member of a committee; or 

                       (2) DETERMINATION BY COMMITTEE.  In a matter not falling
within (1) next preceding if either a majority of disinterested members of the
Board of Directors or a majority of a committee of disinterested shareholders of
the corporation, (excluding therefrom any Director, officer or member of a
committee) selected as hereinafter provided shall determine that he was not
willfully derelict.  Such determination shall be made by the disinterested
members of the Board of Directors except where such members shall determine that
such matter should be referred to said committee of disinterested shareholders.

                       (c) SELECTION OF COMMITTEE.  The selection of a
committee of shareholders provided above may be made by the Majority vote of the
disinterested Directors or, if there be no disinterested Director or Directors,
by the chief executive officer of the corporation.  A Director or


                                      13
<PAGE>

shareholder shall be deemed disinterested in a matter if he has no interest 
therein other than as a Director or shareholder of the corporation as the 
case may be.  The corporation shall pay the fees and expenses of the 
shareholders or Directors, as the case may be, incurred in connection with 
making a determination as above provided.

                       (d) NON-COMMITTEE DETERMINATION.  In the event that a
Director, officer or member of a committee shall be found by some other method
not to have been willfully derelict in the performance of his duty as such
Director, officer or member of a committee, then such determination as to
dereliction shall not be questions on the ground that it was made otherwise than
as provided above.

    Re:Merger of Predecessor Companies Into Papnet of Ohio, Inc.

Gentlemen:

    This opinion is furnished with respect to the Registration Statement on
Form S-4 (the "Registration Statement") being filed by Papnet of Ohio, Inc.
("Papnet") with the Securities and Exchange Commission related to the
registration of 4,850,033 shares of Papnet common stock, no par value (the
"Stock"), to be issued in connection with the proposed merger (the "Merger") of
Cytology Indiana, Inc., Indiana Cytology Review Company, ER Group, Inc., CCWP
Partners, Inc., and Carolina Cytology, Inc. (collectively "Predecessor
Companies"), with and into Papnet.

    We are counsel for Papnet and have participated in the preparation of the
Registration Statement.  We have reviewed the Agreement and Plan of Merger,
dated as of July 5, 1996, among Papnet and the Predecessor Companies (the
"Merger Agreement"), Papnet's Articles of Incorporation and Code of Regulations,
the proposed Amended and Restated Articles of Incorporation and Regulations of
Papnet, the corporate action taken to date in connection with the Registration
Statement and the issuance and sale of the Stock, and such other documents and
authorities as we deem relevant for the purpose of this opinion.

    Based upon the foregoing, we are of the opinion that:

    (a)  upon the proper approval of the Merger Agreement by the shareholders
         of Papnet and the Predecessor Companies and its filing with the Ohio
         Secretary of State;

    (b)  upon the proper approval of the Amended and Restated Articles of
         Incorporation of Papnet by the shareholders of Papnet and its filing
         with the Ohio Secretary of State;

<PAGE>

Papnet of Ohio, Inc.
______, 1996
Page -2-


    (c)  upon compliance with the Securities Act of 1933, as amended, and with
         the Securities or "blue sky" laws of the states in which the Stock is
         to be offered for sale; and

    (d)  upon satisfaction of all of the conditions stated in the Merger
         Agreement and at the "Effective Time," as defined in the Merger
         Agreement;

the Stock, when issued and delivered as provided in the Merger Agreement in
accordance with the resolutions heretofore adopted by the Board of Directors and
shareholders of Papnet, will be legally issued, fully paid, and nonassessable.

    We consent to the filing of this opinion as an exhibit to the Registration
Statement.

                                       Very truly yours,

                                __________, 1996

Papnet of Ohio, Inc.
6059 Memorial Drive
Dublin, Ohio  43017

Gentlemen:

     We have acted as counsel in connection with the proposed merger (the
"Merger") of  Cytology Indiana, Inc., an Ohio corporation, Indiana Cytology
Review Corporation, an Ohio corporation, ER Group, Inc., an Ohio corporation,
CCWP Partners, Inc., an Ohio corporation, and Carolina Cytology, Inc., an Ohio
corporation,  (the foregoing companies referred to individually as a
"Predecessor Company" and collectively as the "Predecessor Companies") with and
into Papnet of Ohio, Inc., an Ohio corporation (the "Company"), pursuant to
which the stockholders of the Predecessor Companies will receive shares of
common stock, without par value, of the Company ("Company Shares") subject to
the Agreement and Plan of Merger, dated as of July 5, 1996, by and among the
Predecessor Companies and the Company (the "Merger Agreement") in exchange for
their shares of the outstanding common stock of the Predecessor Companies.  At
your request, and pursuant to Section 7.01(h) of the Merger Agreement, we are
rendering our opinion concerning certain federal income tax consequences of the
Merger.

     In that connection, we have examined and relied upon originals, or copies
certified or otherwise identified to our satisfaction, of such records,
documents and other instruments, and such  other matters of fact and law, as we
have considered necessary or appropriate for the purposes of this opinion,
including an examination of: (i) the Merger Agreement and the other documents
and agreements referred to therein;  and (ii) the Information
Statement/Prospectus (the "Prospectus") relating to the Merger and included in
the Registration Statement of the Company on Form S-4 filed by the Company with
the Securities and Exchange Commission.  In our examination, we have assumed the
legal capacity of all natural persons, the genuineness of all signatures, the
authenticity of all documents submitted to us as originals, the conformity to
the original documents of all documents submitted to us as certified or
photostatic copies, and the authenticity of the originals of such latter
documents.

     For purposes of the opinions set forth below, we have assumed the accuracy
and completeness of the statements and representations (which statements and
representations we have neither investigated nor verified and upon which we are
entitled to rely) contained, respectively, in certain certificates of the
officers of the Company and the Predecessor Companies and certain stockholders
of the Predecessor Companies, and that the certificates will be executed as of
the Effective Time as defined in the Merger Agreement.  We have also assumed
that the transactions


<PAGE>

Papnet of Ohio, Inc.
______________, 1996
Page 2

contemplated by the Merger Agreement have been consummated in accordance with
the Merger Agreement, the Merger constitutes a merger pursuant to the applicable
provisions of the laws of the State of Ohio, and the facts, statements and other
information contained in the Prospectus relating to the Merger are true, correct
and complete in all material respects.

     The opinions set forth below are based upon, and the section numbers cited
herein refer to, the Internal Revenue Code of 1986, as amended (the "Code"), the
Treasury Regulations promulgated thereunder, the administrative interpretations
thereof and the judicial decisions with respect thereto, all as currently in
effect, and are further based upon the assumption that the documents,
certifications and representations referred to in the two preceding paragraphs
have been finalized and executed at the Effective Time.

     In reliance on the assumptions and the representations set forth above and
the continued accuracy and completeness of the statements and certifications
identified above, and further assuming that the stockholders of the Predecessor
Companies do not, for a sufficient period of time to meet the continuity of
interest requirements for a reorganization, sell, exchange, transfer by gift or
otherwise dispose of a number of Company Shares received in the Merger that
would reduce the ownership of Company Shares by the former stockholders of the
Predecessor Companies to a number of shares having a value, as of the date of
the Merger, of less than 50 percent of the total value of all the formerly
outstanding stock of the Predecessor Companies as of the same date, we are of
the opinion that:


     (1)  The Merger of the Predecessor Companies with and into the Company will
          constitute a reorganization within the meaning of Section 368(a) of
          the Code.

     (2)  The Predecessor Companies and the Company will each be "a party to a
          reorganization" within the meaning of Section 368(b) of the Code.

     (3)  None of the Predecessor Companies nor the Company will recognize gain
          or loss (except for the inclusion in income of amounts resulting from
          any required change in accounting methods or similar items) as a
          result of the Merger.

     (4)  No gain or loss will be recognized by the stockholders of the
          Predecessor Companies upon the exchange of their respective shares of
          a Predecessor Company stock for Company Shares pursuant to the Merger,
          except that a stockholder of a Predecessor Company  will recognize
          gain, if any, upon receipt of cash in payment of dissenter's rights of
          appraisal.


<PAGE>

Papnet of Ohio, Inc.
______________, 1996
Page 3

     (5)  The federal income tax basis of the Company Shares received by the
          stockholders of the Predecessor Companies in exchange for their
          Predecessor Company stock will be the same federal income tax basis of
          the Predecessor Company stock surrendered in the exchange therefor.

     (6)  The holding period for the Company Shares received by the stockholders
          of the Predecessor Companies in exchange for their Predecessor Company
          stock will include the period for which the Predecessor Company stock
          exchanged therefor were held, provided the exchanged Predecessor
          Company stock was held as a capital asset by such stockholder on the
          date of the Merger.

     We have given this opinion pursuant to Section 7.01(h) of the Agreement in
connection with the transactions contemplated thereby and such opinion is not to
be relied upon for any other purpose.  This opinion may not be applicable to:
(1) a Predecessor Company stockholder whose Predecessor Company stock is not
held as a capital asset; (2)  a Predecessor Company stockholder who is subject
to special treatment under the Code, including without limitation, insurance
companies, dealers in securities, financial institutions, tax-exempt investors
or non-United States citizens; or (3) the extent that the Company and/or the
Predecessor Companies are investment companies within the meaning of Section 368
of the Code.  This opinion assumes that no Predecessor Company was formed, and
no stockholder acquired stock in any Predecessor Company, in contemplation of or
to effectuate the Merger.

     In addition to the assumptions and exclusions above, no opinion is
expressed herein concerning the tax treatment of the Merger under other
provisions of the Code and the Treasury Regulations issued thereunder,
including, without limitation: (1) the exchange of any shares of a Predecessor
Company in the Merger that were acquired by the holder thereof pursuant to any
employee stock option or employee stock purchase plan or otherwise as
compensation; (2) the effect of Section 731(c) on any subsequent distribution of
the Company Shares by a Predecessor Company stockholder; and (3) the effect of
state, local, and foreign tax laws.  Furthermore, no opinion is expressed herein
about the tax treatment of any conditions existing at the time of, or effects
resulting from, the transaction that are not specifically addressed by the
foregoing opinion.

     You should be aware that this opinion represents our conclusions as to the
application of existing law and is based on the certifications and
representations given as of the date hereof.  The statutory provisions,
regulations, interpretations, and other authorities upon which our opinion is
based are subject to change, and such changes could apply retroactively.  In
addition, no advance ruling has been obtained from the Internal Revenue Service,
and there can be no assurance that positions contrary to those stated in our
opinion will not be taken by the Internal Revenue Service.  No person other than
the addressee named herein may rely on this opinion for any purpose.

                       AMENDED AND RESTATED AGREEMENT


     THIS AMENDED AND RESTATED AGREEMENT, dated as of _________________, 
1995, is by and between NEUROMEDICAL SYSTEMS, INC., a Delaware corporation 
("NSI"), with its principal place of business at Two Executive Boulevard, 
Suffern, New York  10901, and ____________, a Delaware corporation 
("Licensee"), with its principal place of business at ____________________ 
(this "Agreement").  This Agreement supersedes and replaces any and all prior 
agreements by and between NSI and Licensee and any of its 
predecessors-in-interest, including, without limitation, Papnet of Ohio, 
Inc., an Ohio corporation ("Papnet of Ohio"), Papnet Indiana Limited 
Partnership, an Ohio limited partnership, Papnet West Limited Partnership, an 
Ohio limited partnership, ER Group, Inc., an Ohio corporation, Carolina 
Cytology Licensing Company, an Ohio general partnership, Cytology West, Inc., 
a Delaware corporation, and Papnet Utah, Inc., a Nevada corporation.

     WHEREAS, NSI has designed, developed and produces the PAPNET-Registered 
Trademark- Testing System ("PAPNET-Registered Trademark-," "PAPNET-Registered 
Trademark- System" or "PAPNET-Registered Trademark- Testing"), which is a 
semi-automated system for the review of cell, tissue or body fluid specimens 
("Slides") including, but not limited to, cervical cytology specimens; 

     WHEREAS, the PAPNET-Registered Trademark- System consists of a scanning 
system (the "Scanner"), which processes Slides and stores digital images of 
certain portions of such Slides on a digital tape ("PAPNET-Registered 
Trademark-Images"), and a proprietary review station (the "Review Station"), 
which, among other things, permits a cytotechnologist trained by NSI to 
review the images stored on the digital tape; 

     WHEREAS, NSI markets and sells PAPNET-Registered Trademark- Testing as a 
service, by which end-user laboratories submit Slides to one of NSI's central 
facilities for processing on a Scanner ("Scanning Centers"), and NSI returns 
such Slides and the related digital tape containing PAPNET-Registered 
Trademark-Images to such laboratories so that NSI-trained cytotechnologists 
employed by such laboratories may review the Slides and the related 
PAPNET-Registered Trademark- Images using a licensed, leased or purchased 
Review Station (the scanning of Slides and the use of the Review Station 
(whether by license, lease or purchase) are collectively referred to herein 
as the "PAPNET-Registered Trademark- Service");

     WHEREAS, NSI has been granted patents #4,965,725, #5,287,182, 
#5,287,272, and _______ by the United States government, covering the use of 
neural networks for the classification of cell, tissue or body fluid 
specimens, and has certain other patents and patent applications issued and 
pending in the United States and elsewhere and has or will have certain other 
patents in development relating to the PAPNET-Registered Trademark- System or 
the PAPNET-Registered Trademark-Service (the "Patents"); and 
 
     WHEREAS, NSI has used the trademarks and trade names "Neuromedical 
Systems", "NSI", "PAPNET-Registered Trademark-" and its "box" logo and may 
use other names or marks to identify or describe the PAPNET-Registered 
Trademark-Service (the Patents and all pending and future worldwide patents 
and patent rights, copyrights, trademarks, trade names, trade secrets, 
know-how, utility models, improvements thereon

<PAGE>

and other intellectual property rights in and to the PAPNET-Registered 
Trademark- System or the PAPNET-Registered Trademark-Service, including 
without limitation, all applications and registrations with respect thereto, 
are collectively referred to as the "Intellectual Property"); and

     WHEREAS, Licensee acknowledges NSI's exclusive right in and to the 
Intellectual Property and the use thereof and NSI acknowledges Licensee's 
limited rights to use the Intellectual Property as provided herein; and 

     WHEREAS, NSI wishes to enter into this Agreement with Licensee to amend 
and restate its previous agreement with Licensee and any of its 
predecessors-in-interest and to reflect the business combination into 
Licensee of Papnet of Ohio, Inc. Papnet Indiana Limited Partnership, Papnet 
West Limited Partnership, Cytology West, Inc., Carolina Cytology Licensing 
Company, ER Group, Inc., and Papnet Utah, Inc., which were formerly licensees 
of NSI; and

covenants herein contained, and for other good and valuable consideration, 
the receipt and sufficiency of which are hereby acknowledged, it is hereby 
agreed as follows:

percent (10%) or more of their annual Slide volume originating from patients 
located within the Licensed Territory.   The parties will annually evaluate 
the Slide volumes of clinical laboratory companies in the United States to 
identify the laboratory companies that meet this definition.

Licensee hereunder shall not prohibit NSI from conducting sales activities in 
the Licensed Territory directly through NSI's national sales force and 
marketing in the Licensed Territory, provided that NSI gives Licensee 
reasonable advance notice of such activities.

     2.2  MARKETING AND SALES. 

     (a) Licensee agrees to use reasonable efforts to promote and sell the 
PAPNET-Registered Trademark- Service within the Licensed Territory.  Licensee 
will conduct such activities as it undertakes in accordance with marketing 
and sales policies and procedures of uniform national application promulgated 
from time to time by NSI's Vice President of Marketing and Sales, its 
Director of Sales, or such other person as NSI shall appoint for such 
purpose. Licensee will provide periodic sales reports and other sales-related 
information and internal reports to NSI as provided in such uniform policies 
adopted by NSI from time to time, and otherwise on the same basis as such 
information and reports are provided to Licensee's management, including 
assistance to NSI's Director of Sales in the preparation of monthly master 
production schedules.  Licensee's Sales Manager shall also have access to 
such NSI sales data on the same basis as NSI's Director of Sales and shall 
promptly receive copies of internal NSI reports related to same. 
Notwithstanding the foregoing, NSI data relating to regions outside of the 
Licensed Territory (including aggregate national data) for any fiscal period 
of NSI shall not be required to be made available to Licensee until after NSI 
has filed its applicable periodic report as required under Section 13 of the 
Securities Exchange Act of 1934, and any  material nonpublic sales 
information of Licensee for any fiscal period of Licensee shall not be 
required to be made available to NSI until after Licensee has filed its

under this Section 2.2(a) shall be received by such other party subject to 
reasonable policies of the providing party regarding the use and disclosure 
of confidential information as the same are applicable to the providing 
party's officers and employees.
     
      (b) NSI shall have authority over the marketing and selling materials and
methods relating

                                        5

to the PAPNET-Registered Trademark- Service. Licensee shall provide only 
NSI-approved marketing materials to Clients. NSI shall make available to 
Licensee, for a charge not to exceed NSI's actual per-unit incremental cost 
(exclusive of charges for design and other creative services), all such 
brochures, pamphlets, reprints and other marketing and sales materials as are 
available to NSI, in sufficient quantities for Licensee to conduct efficient 
marketing activities in the Licensed Territory; provided, however, that if 
use of any such materials is mandated by NSI, NSI shall bear the entire costs 
thereof.  Licensee may also reproduce marketing materials obtained from NSI 
for use in conducting Licensee's marketing activities, provided that such 
reproduction shall be of equal or better quality.  As requested by Licensee, 
NSI will use reasonable efforts to make available to Licensee other 
information, data, reprints and public speakers to aid in the promotion of 
the PAPNET-Registered Trademark- Service within the Licensed  Territory, on 
reasonable terms and conditions.  

     (c) Licensee shall obtain prior written approval from NSI for the use of 
any marketing materials for the PAPNET-Registered Trademark- Service which 
may be independently developed by Licensee.  Any such request shall be made 
in writing to NSI's Vice President of Marketing, with a copy to NSI's General 
Counsel.  NSI will promptly respond in writing to any such request; failure 
to respond within 30 days of receipt of any such request which has been 
delivered by certified mail shall constitute approval by NSI of such 
materials.  NSI will have the ability to approve or deny use of such 
materials in the exercise of its reasonable discretion.  All marketing 
materials independently developed by Licensee incorporating the Intellectual 
Property or relating to the PAPNET-Registered Trademark- System or the 
PAPNET-Registered Trademark- Service shall clearly indicate Licensee's 
relationship with NSI.

     (d) Should NSI engage in advertising in visual,  audio or print media or 
direct mail or direct response campaigns, or other similar methods of 
promoting the PAPNET-Registered Trademark- Service, which are substantially 
national in scope and tenor, NSI shall conduct a level of  such promotional 
efforts in the Licensed Territory proportionate to the level of population 
within the Licensed Territory.  NSI shall bear the cost of any such 
advertising or promotional activities which it conducts within the Licensed 
Territory.  

     (e)  NSI agrees to use reasonable efforts to inform Licensee of its 
marketing and sales efforts in the Licensed Territory.  NSI will use 
reasonable efforts to provide Licensee the opportunity to participate in the 
implementation of marketing policies, strategies, and programs and will use 
its reasonable efforts to provide a representative of Licensee the 
opportunity to attend, either by phone or in person, all relevant meetings 
and other programs of NSI that relate to implementation of such policies, 
strategies and programs, or to any marketing, sales or customer relations 
activities in the Licensed Territory.

     (f)  NSI agrees to cooperate with Licensee and to provide without charge 
its facilities and employees in arranging and conducting product 
demonstrations, tours of NSI facilities, meetings with NSI executives, and 
similar activities in connection with Licensee's marketing, sales and public 
relations efforts, upon reasonable prior notice and during normal business 
hours.

     2.4  SALES PERSONNEL.   Licensee will consult with and give reasonable
consideration to NSI's

                                       6

<PAGE>

evaluations and recommendations regarding the employment and retention of 
sales representatives of Licensee who market and sell the PAPNET-Registered 
Trademark- Service, and such evaluations and recommendations will be based 
upon criteria similar to those employed by NSI in the hiring and retention of 
its own sales force.  NSI shall provide without cost to Licensee initial and 
periodic training of Licensee's sales personnel to the same extent and on the 
same basis that such training is provided to NSI's sales personnel, and shall 
keep Licensee's sales personnel updated with appropriate sales materials and 
other  information.  Licensee agrees to cause its sales personnel to 
participate in periodic marketing or sales meetings and conference calls 
conducted by NSI for its national sales force, and NSI will bear the costs of 
travel and lodging for meetings or other programs at which attendance by 
Licensee's sales personnel is requested by NSI.

adopt concerning the use of NSI's copyrights, trademarks and trade names by 
NSI personnel, distributors and other representatives.  Licensee shall have 
the right to reproduce NSI's trademarks and logos on its business cards, 
letterhead stationery, and corporate communications, provided that such 
materials indicate Licensee's relationship with NSI. Licensee shall not use 
NSI's copyrights, trademarks or trade names in a disparaging manner.  
Licensee shall not take any action which is inconsistent with NSI's ownership 
of its copyrights, trademarks and trade names, and agrees that each of the 
foregoing shall inure to the benefit of NSI.  NSI agrees to include correct 
trademark, trade name, copyright, trade secret and patent notices for the 
PAPNET-Registered Trademark- System and the PAPNET-Registered Trademark- 
Service on all materials and equipment where appropriate.  Licensee shall not 
remove, alter, cover, obfuscate or otherwise deface any NSI trademark, trade 
name, patent, trade secret or copyright notice on the PAPNET-Registered 
Trademark- System or any part thereof or on any promotional or advertising 
material used in conjunction with or for the PAPNET-Registered Trademark- 
System or the PAPNET-Registered Trademark- Service.  The foregoing provisions 
shall also apply to any other NSI Technology licensed to Licensee hereunder.  
Licensee agrees not to represent that any product or service sold by it in 
conjunction with the PAPNET-Registered Trademark- System or the 
PAPNET-Registered Trademark- Service, and which is not licensed by NSI, is a 
product or service manufactured, provided or endorsed by NSI.

     2.6  NATURE AND SCOPE OF APPOINTMENT.   Licensee shall not knowingly 
market, distribute, sell or license the PAPNET-Registered Trademark- System 
or the PAPNET-Registered Trademark- Service outside of the Licensed Territory 
or for any  use, other than as permitted by NSI; provided, however, that 
activities of Licensee outside the Licensed Territory reasonably incidental 
to marketing and sales activities within the Licensed Territory shall not be 
a violation of this Section 2.6.   Licensee shall not, nor shall it encourage 
or assist any third party to, make use of the PAPNET-Registered Trademark- 
System other than as permitted or recommended by NSI and indicated by the 
PAPNET-Registered Trademark- System's labeling.  Nothing contained in this 
Agreement shall prohibit NSI from making, using, licensing, distributing, 
selling or granting any rights in and to the PAPNET-Registered Trademark- 
System or the PAPNET-Registered Trademark- Service outside of the Licensed 
Territory so long as there is no material effect on Licensee's exclusive 
rights within the Licensed Territory. 

                                       7

<PAGE>

     2.7  REGULATORY COMPLIANCE. NSI agrees to promptly advise Licensee in 
writing of its policies with regard to governmental regulations affecting the 
PAPNET-Registered Trademark- System or the PAPNET-Registered Trademark- 
Service and any changes in such policies which may occur from time to time.  
Licensee agrees that any marketing or use of the PAPNET-Registered Trademark- 
System or the PAPNET-Registered Trademark- Service shall conform to NSI's 
practices or policies with respect to compliance with governmental 
regulations.  Licensee agrees to use its reasonable efforts to cause its 
sales force to operate in strict compliance with NSI's policies and 
practices, and generally with all applicable governmental regulations 
applicable to their activities.

     2.8  GOVERNMENTAL RESTRICTIONS.  To the extent that any court, 
governmental body or regulatory agency with jurisdiction over NSI or Licensee 
restricts or prohibits the marketing, distribution, provision or licensing of 
the PAPNET-Registered Trademark- System or the PAPNET-Registered Trademark-

such restriction or prohibition without liability to NSI of any type or 
nature except as expressly provided herein to the contrary.

Technology" hereunder. 

3.  ROYALTIES.

     3.1  AMOUNT AND PAYMENT.   

          (a) With respect to each fiscal month during the Term of this 
Agreement NSI shall be obligated to pay Licensee Royalties equal to fifty 
percent (50%) of the amount by which Territory Gross Revenues recognized by 
NSI during such month exceeds the sum of the Lease Service Costs and Slide 
Transportation Costs associated with the Slides processed during such month; 
provided, however, that the total amount of Royalties payable under this 
Section 3.1(a) with respect to any fiscal year of NSI shall not exceed the 
amount of Royalties determined with respect to Territory Gross Revenues 
recognized by NSI from the processing of the first 12,175,000 Revenue Slides 
for such fiscal year which originate in the Licensed Territory.  

          (b) Notwithstanding the provisions of Section 3.1(a),  in the event 
that the aggregate amount of monthly Royalties paid with respect to any 
fiscal year of NSI shall be less than four and fifteen hundredths percent 
(4.15%) of NSI's Worldwide Gross Revenues for such fiscal year, NSI shall pay 
to Licensee as additional Royalties the amount of such difference; provided, 
however,  that the total amount of Royalties payable under this Section 
3.1(b) with respect to any fiscal year of NSI shall not exceed an amount 
equal to (i) Twenty Three Million Dollars ($23,000,000), less (ii) the total 
amount of Royalties payable under Section 3.1(a) with respect to such fiscal 
year.

          (c)  The Royalties due with respect to any fiscal month shall be
reported by NSI to Licensee within fifteen (15) days after the conclusion of
such month, and shall be paid by NSI to

                                       8

<PAGE>

Licensee as soon as possible, but not later than thirty (30) days, after the 
conclusion of such month.  Any additional Royalties payable pursuant to 
Section 3.1(b) shall be reported and paid by NSI to Licensee not later than 
ninety (90) days after the end of the fiscal year with respect to which such 
additional Royalties are due.   Royalty reports furnished by NSI to Licensee 
pursuant to this Section 3.1(c) shall set forth the calculation of the 
Royalties in reasonable detail so that Licensee can determine the accuracy 
thereof.  Royalties shall be paid by check or wire transfer.
               
          (d) NSI's obligation to pay any Royalties due under this Section 
3.1 shall not be subject to any conditions or limitations other than as 
provided in this Section.
          
          (e)  For purposes of determining Licensee's share of Territory 
Gross Revenues during any applicable period, there shall be included in 
Territory Gross Revenues during such period a proportionate share of gross 
revenues recognized by NSI arising directly or indirectly from the sale, 
licensing or use of the PAPNET-Registered Trademark- System, 
PAPNET-Registered Trademark-Service, and/or any NSI Technology to Multistate 
National Laboratories, without any allowances, credits or deductions (other 
than such as would constitute price rebates, in the form of  discounts or 
other reductions in the effective price per Slide charged to Clients), 
regardless of whether the Revenue Slides attributable to such Multistate 
National Laboratories actually originate in the Licensed Territory.  Such 
proportionate share  shall be equal to the ratio which the population of the 
Licensed Territory bears to the population of the United States, as 
determined from time to time from the most recently available United States 
census data.  As of the date of this Agreement, such ratio is ___ percent.  
In determining the amount of Royalties payable during any applicable period 
with respect to such proportionate share of gross revenues, an amount 
representing Lease Service Costs and Slide Transportation Costs will be 
deducted from Territory Gross Revenues.  Such costs shall be determined by 
multiplying the average per Revenue Slide Lease Service Costs and Slide 
Transportation Costs in the Licensed Territory times the number of Revenue 
Slides represented by the proportionate share of gross revenues from 
Multistate National Laboratories included in the Territory Gross Revenues.

          (f)  In the event that the PAPNET-Registered Trademark- System, 
PAPNET-Registered Trademark- Service, and/or any NSI Technology is ever 
applied by NSI to the processing of Slides other than cervical cytology 
specimens (I.E.,"PAP" smears), the parties will in good faith negotiate an 
increase in the Royalties cap contained in Section 3.1(a) above to accord 
Licensee a share of the additional Territory Gross Revenues attributable to 
such new Slide processing business, which is proportionate to the ratio which 
the population in the Licensed Territory bears to the total population of the 
United States at the time.

     3.2  BOOKS AND RECORDS.  NSI agrees to keep full and accurate books and 
records showing all billings, Territory Gross Revenues, Worldwide Gross 
Revenues. Lease Service Costs, Slide Transportation Costs and Revenue Slide 
geographic origin in sufficient detail to enable Royalties to be determined 
and paid by it under this Article 3.  NSI further agrees that Licensee and 
its representatives shall be permitted to inspect such books and records from 
time to time during regular business hours and to make such copies thereof as 
reasonably appropriate.  Licensee shall be entitled to have such books and 
records audited by a certified public accountant at Licensee's expense, and 

                                       9

<PAGE>

NSI agrees to place at the disposal of Licensee's accountant all books and 
records necessary or desirable in connection with such audit and to give such 
auditor reasonable assistance and cooperation.  The cost of any such 
inspection or audit shall be borne by Licensee.  

     3.3  CALCULATION OF GROSS REVENUES.  The determination of NSI's 
independent auditor as to Worldwide Gross Revenues for any fiscal year shall 
be deemed presumptively correct.  If disputed, Licensee shall have the right 
to make reasonable inquiry as to the method by which Worldwide Gross Revenues 
have been calculated and NSI shall instruct its auditor to provide a prompt 
and thorough response to such inquiry.  Any and all disputes concerning the 
determination of Territory Gross Revenues or Worldwide Gross Revenues shall 
be subject to arbitration as provided in Section 13 of this Agreement.

     3.4  REMEDY FOR NON-PAYMENT OF ROYALTIES. Without limiting any other 
rights or remedies to which Licensee may be entitled hereunder, in the event 
of the failure of NSI to pay Licensee any Royalties when required to be paid 
under Section 3.1(c), interest thereon shall accrue monthly at the rate of 
1.5% (18% per annum).

4. CONTRACT TERMS AND PROCEDURES; CLIENT TRAINING AND SERVICE.

     4.1 GENERAL.  NSI shall provide Licensee with its standard form or forms 
of End User License and other forms of contracts to be executed between NSI 
and Clients, which shall be used by Licensee and NSI in the Licensed 
Territory. Licensee and NSI shall cooperate in negotiating the definitive 
terms of such contracts between NSI and Clients in the Licensed Territory.  
NSI agrees to comply with the terms of any End User License it enters into

     4.2 CONTRACTING OBLIGATIONS OF NSI.  NSI shall enter into contracts with

added customer benefits, and exceptions as it does in the remainder of the

contract with a Client in the Licensed Territory except upon grounds stated 
in NSI's written policies and procedures of uniform national application 
which have been provided to Licensee.  In the event of such a delay or 
refusal, NSI shall promptly provide written notice to Licensee of such delay 
or refusal and the detailed grounds therefor, and shall cooperate with 
Licensee's efforts to remedy any noted deficiencies.                      

     4.3  NONDISCRIMINATION.  NSI agrees that pricing, discounts and
concessions, delivery schedules, and other contract terms of the PAPNET-
Registered Trademark- Service provided to Clients within the Licensed Territory,
as well as the quality and timeliness of service to them, will be no less
favorable to such Clients than for laboratories, insurance companies or other
purchasers in any other region or locality within the United States, except to
the extent that NSI can demonstrate that any variance in pricing, discounts and
concessions, or other contract terms is proportionate to differences in the cost
of servicing a particular customer.  Notwithstanding the foregoing, if NSI shall
enter into agreements with laboratories, insurance companies or other purchasers
on economic or business terms materially different than provided to Clients
within the Licensed Territory, at Licensee's

                                      10

<PAGE>

request, NSI shall extend such differing terms to Clients in the Licensed 
Territory with comparable costs of service.  In order to assess NSI's 
compliance with this Section 4.3, NSI will permit Licensee to inspect, during 
normal business hours, NSI's contract files for Clients located outside of 
the Licensed Territory.  The provisions of this Section 4.3 shall not impose 
any obligation on NSI to extend pricing, discounts, concessions, or other 
contract terms applicable to Multistate National Laboratories to Clients in 
the Licensed Territory.

     4.4 TRAINING AND REVIEW STATIONS.  NSI shall provide training in the 
operation and maintenance of the Review Station and the evaluation of 
PAPNET-Registered Trademark- Images to personnel of Clients in the Licensed 
Territory, on terms and schedules comparable to those offered to Clients 
outside the Licensed Territory.  NSI will notify Licensee of any anticipated 
delays in the delivery of Review Stations or in training of Client personnel 
of greater than thirty (30) days after execution and delivery of the End User 
License and other standard contract forms required by NSI.

acknowledges and agrees that NSI is the sole and exclusive owner of the 
Intellectual Property embodied in the PAPNET-Registered Trademark- System, 
all information, materials, clinical and test data reports and filings 
produced in connection with any required regulatory approvals, permits and 
licenses, and all information, reports, specifications, source code, object 
code, documentation, diagrams, flow charts and any other tangible or 
intangible materials of any type whatsoever relating to the PAPNET-Registered 
Trademark- System and derived or produced by  or on behalf of NSI 
(collectively, the "Proprietary Materials"). No provision contained in this 
Agreement shall be construed to transfer to Licensee any title or ownership 
interest in the Proprietary Materials or any Intellectual Property embodied 
in  the PAPNET-Registered Trademark- System or the PAPNET-Registered 
Trademark- Service.  

     9.2  SCOPE OF USE.  Licensee shall not, and shall not knowingly assist 
any third party to, (a) modify or alter, create or attempt to create, by 
reverse engineering or otherwise, translate or decompile, translate or 
transfer, or otherwise attempt to derive the source code, structure or 
algorithms of, the PAPNET-Registered Trademark- System or any part thereof, 
(b) use or adapt the PAPNET-Registered Trademark- System or any part thereof 
in any way, otherwise than in connection with the marketing or sale of the 
PAPNET-Registered Trademark- Service, (c) use the PAPNET-Registered 
Trademark- System or any part thereof to create a derivative work of the 
PAPNET-Registered Trademark- System or (d) rent, lease or otherwise provide 
temporary access to the PAPNET-Registered Trademark- System or any part 
thereof,  except as incidental to marketing and sales activities otherwise 
permitted under this Agreement.

     9.3  CONTROL OF INTELLECTUAL PROPERTY PROTECTION.  NSI shall at all 
times retain the sole and exclusive right to pursue, secure, maintain, 
protect and enforce its Intellectual Property rights in and to, or arising 
out of or related to, the PAPNET-Registered Trademark- System or the 
PAPNET-Registered Trademark-Service.

     9.4  PAPNET-Registered Trademark- SYSTEM NAME.  NSI shall have the right 
in its sole discretion to select and include any trademark or trade name to 
identify the PAPNET-Registered Trademark- System, provided that Licensee will 
have only the same rights with respect to any such trademark or trade name as 
it does to other trademarks and trade names of NSI hereunder.

     9.5  PROTECTION OF INTELLECTUAL PROPERTY.  Licensee shall use its
reasonable efforts to protect and maintain the protection of the Intellectual
Property, as the same may be modified, upgraded or enhanced from time to time. 
Upon NSI's request, Licensee shall, at NSI's sole cost and expense, assist NSI
in securing, maintaining and enforcing NSI's Intellectual Property rights in and
to the

                                      13

<PAGE>

PAPNET-Registered Trademark- System or the PAPNET-Registered 
Trademark-Service, including, but not limited to, undertaking any and all 
necessary and appropriate actions in accordance with NSI's requests.  

     9.6  NOTICE OF INFRINGEMENT.  Licensee shall promptly notify NSI of any 
infringement of any Intellectual Property right of NSI with respect to the 
PAPNET-Registered Trademark- System or the PAPNET-Registered Trademark- 
Service which is known to Licensee.  Upon reasonable notice of infringement, 
NSI shall have the right, but not the obligation, to bring any suit or action 
for infringement of its Intellectual Property at its own expense.  Licensee 
shall, if requested by NSI, actively assist in the prosecution of such 
action.  All costs for such assistance shall be paid by NSI.  

     9.7  INFRINGEMENT.  If, as a result of any claim of infringement, 
Licensee or NSI is permanently enjoined from selling the PAPNET-Registered 
Trademark-Service or using the PAPNET-Registered Trademark- System, as the 
case may be, by a final, nonappealable decree of a court of competent 
jurisdiction, NSI shall, if possible, replace or modify the PAPNET-Registered 
Trademark- System or PAPNET-Registered Trademark- Service so that the  
PAPNET-Registered Trademark-Service or PAPNET-Registered Trademark- System is 
non-infringing, or procure for Licensee the right to continue to sell the 
PAPNET-Registered Trademark- Service or use the PAPNET-Registered Trademark- 
System that is subject to such decree. In the event that Licensee or NSI is 
either preliminarily or permanently enjoined from marketing and distributing 
the PAPNET-Registered Trademark-Service in the Licensed Territory, but NSI is 
legally free to offer the PAPNET-Registered Trademark- Service in other parts 
of the United States or the world, then Licensee shall continue to be 
entitled for the period it is so enjoined during the Term of this Agreement 
to Royalties as provided in Section 3.1(b) of this Agreement.  Except for the 
indemnification provided in Section 10.1(ii), the foregoing states the entire 
liability of Licensee or NSI, as the case may be, to the other with respect 
to infringement of any proprietary rights of any third party, and Licensee 
and NSI hereby expressly waive any other such liabilities that each may have 
against the other and its directors, officers, employees, agents, 
representatives and affiliates. 

10.  INDEMNIFICATION.  

     10.1  INDEMNIFICATION BY NSI.  NSI shall, at its sole cost and expense, 
indemnify and hold  Licensee and its directors, officers, employees, agents, 
representatives and affiliates harmless with respect to any liabilities, 
damages, losses, costs and expenses, including reasonable attorney's fees 
(any or all of the foregoing being hereinafter referred to as a "Loss"), 
insofar as such Loss arises out of or is based upon (i) a misrepresentation 
or breach (or alleged misrepresentation or breach) by NSI of its warranties, 
covenants and agreements contained herein, (ii) a claim that the 
PAPNET-Registered Trademark-System, the PAPNET-Registered Trademark- Service, 
the Intellectual Property, the Patents, or the NSI Technology licensed 
hereunder, as used within the scope of this Agreement, infringes or violates 
any proprietary rights of any third party; or (iii) any injury to person or 
property resulting from use of the PAPNET-Registered Trademark- System, the 
PAPNET-Registered Trademark- Service, or other NSI Technology, except to the 
extent that such injury is proximately caused by the gross negligence or 
intentional misconduct of Licensee or Licensee's employees.

     10.2  INDEMNIFICATION BY LICENSEE.   Licensee shall, at its sole cost 
and expense, indemnify and hold NSI and its directors, officers, employees, 
agents, representatives and affiliates harmless

                                      14

<PAGE>

with respect to any liabilities, damages, losses, costs and expenses, 
including reasonable attorney's fees (any or all of the foregoing being 
hereinafter referred to as a "Loss"), insofar as such Loss arises out of or 
is based upon a misrepresentation or breach (or alleged misrepresentation or 
breach) by the Licensee of its warranties, covenants and agreements contained 
herein. 

     10.3  NOTICE OF CLAIM; DEFENSE.  Each person indemnified under Sections 
10.1 and 10.2 above (an "Indemnified Person")  agrees that, upon the service 
of a summons or other initial legal process upon the Indemnified Person in 
any action or proceeding, or upon the Indemnified Person's receipt of written 
notification of the commencement of any investigation, inquiry, or proceeding 
in respect of which indemnity may be sought by the Indemnified Person under 
Section 10.1 or 10.2 above, the Indemnified Person will promptly give written 
notice (the "Notice") of such service or notification to the party from whom 
indemnification may be sought hereunder (the "Indemnifying Party").  No 
indemnification provided for in Section 10.1 or 10.2 above shall be available 
to any Indemnified Person who shall fail so to give the Notice, if the 
Indemnifying Party to whom such Notice was not given was unaware of the 
action, suit, investigation, inquiry or proceeding to which the Notice would 
have related, to the extent the Indemnifying Party was prejudiced by the 
failure to give the Notice; but the omission so to notify such Indemnifying 
Party of any such service or notification shall not relieve such Indemnifying 
Party from any liability which it may have to any Indemnified Person for 
contribution or otherwise than on account of such Sections.  An Indemnifying 
Party shall be entitled at its own expense to participate in the defense of 
any action, suit or proceeding against, or investigation or inquiry of, an 
Indemnified Person.  An Indemnifying Party shall be entitled, if it so elects 
within a reasonable amount of time after receipt of the Notice, by giving 
written notice (herein called the "Notice of Defense") to all Indemnified 
Persons, to assume the entire defense of such action, suit, investigation, 
inquiry or proceeding, in which event such defense shall be conducted, at the 
expense of the Indemnifying Party, by counsel chosen by the Indemnifying 
Party reasonably satisfactory to the Indemnified Persons; PROVIDED, HOWEVER, 
that (i) if any Indemnified Person reasonably determines  that there may be a 
conflict between the positions of the Indemnifying Party and of such 
Indemnified Person in conducting the defense of such action, suit, 
investigation, inquiry or proceeding or that there may be legal defenses 
available to such Indemnified Person different from or in addition to those 
available to the Indemnifying Party, then counsel for the Indemnified Person 
shall be entitled to conduct the defense to the extent reasonably determined 
by such counsel to be necessary to protect the interests of the Indemnified 
Person and (ii) in any event, the Indemnified Person shall be entitled to 
have counsel chosen by such Indemnified Person participate in, but not 
conduct, the defense.  If, within a reasonable time after receipt of the 
Notice, an Indemnifying Party gives a Notice of Defense and the counsel 
chosen by the Indemnifying Party is reasonably satisfactory to the 
Indemnified Person, the Indemnifying Party  will not be liable under Section 
10.1 or 10.2 for any legal or other expenses subsequently incurred by the 
Indemnified Person in connection with the defense of the action, suit, 
investigation, inquiry or proceeding, except that (A) the Indemnifying Party 
shall bear the legal and other expenses incurred in connection with the 
conduct of the defense as referred to in clause (i) of the proviso to the 
preceding sentence and (B) the Indemnifying Party shall bear such other 
expenses as it has authorized to be incurred by the Indemnified Person.  If, 
within a reasonable time after receipt of the Notice, no Notice of Defense 
has been given, the Indemnifying Party shall be responsible for any

                                      15

<PAGE>


legal or other expenses incurred by the Indemnified Persons in connection 
with the defense of the action, suit, investigation, inquiry or proceeding.  
No Indemnifying Party will, without the prior written consent of an 
Indemnified Person, settle or compromise or consent to the entry of any 
judgment in any pending or threatened claim, action, suit or proceeding in 
respect of which indemnification may be sought hereunder unless such 
settlement, compromise or consent includes an unconditional release of such 
Indemnified Person and each controlling person thereof from all liability 
arising out of such claim, action, suit or proceeding.

11.  CONFIDENTIALITY.  

     During the Term of this Agreement and thereafter, each of NSI and 
Licensee shall keep strictly confidential all information of the other which 
is secret and proprietary.  The parties shall not reveal or disclose the same 
to any person or entity without the prior written consent of the other party; 
provided, however, that either party may disclose such information pursuant 
to a subpoena, order, statute, rule or other legal requirement promulgated or 
imposed by a court or by a judicial, regulatory or legislative body or agency 
in which such party is involved; and provided, further, that either party may 
disclose to the extent its counsel determines in good faith that such 
disclosure is necessary to comply with applicable securities laws.  In the 
event that either party discloses such confidential information in accordance 
with the previous sentence, such party shall immediately notify the other 
party.

12.  TERM AND TERMINATION.

     (a)  The initial Term of this Agreement shall continue from the date 
hereof until December 31, 2025.  The Term of this Agreement may be extended 
by the Licensee for an additional twenty (20) year Term upon written notice 
to NSI within six (6) months preceding the expiration of the initial Term, 
and the payment to NSI of a renewal fee equal to the net present value of 
twenty (20) years of annual Royalties at the average monthly rate payable in 
the twelve months immediately preceding the date of the notice, determined by 
using a discount rate equal to the prevailing prime rate on the date of the 
notice, as published in the Wall Street Journal.

     (b)  This Agreement may not be terminated or cancelled except upon the 
expiration of its  initial or additional Term other than by written agreement 
of the parties.

     (c)  Upon termination of this Agreement (i) Licensee shall, at its 
expense, return to NSI any of NSI's marketing literature, packaging or 
Confidential Information and all copies thereof in its possession and certify 
in writing that the same have been returned and deliver to NSI all 
information as is necessary and useful for NSI to market the 
PAPNET-Registered Trademark- Service, including, without limitation, 
information in possession of Licensee relating to Clients, (ii) Licensee 
shall immediately cease representing itself as authorized to sell NSI 
products and services, and (iii) the parties shall otherwise cooperate in 
order to effect an orderly termination.

13.  ARBITRATION.  

                                      16

<PAGE>

     Except as otherwise provided herein, the parties hereto agree that the 
sole and exclusive remedy for any dispute between the parties arising out of 
or relating to this Agreement shall be resolved by arbitration conducted in 
The City of Columbus,  Ohio in accordance with the Commercial Arbitration 
Rules then obtaining of the American Arbitration Association, except that the 
arbitrators shall have no power to alter or modify any express provision of 
this Agreement, or to render any award which by its terms effects any such 
alteration or modification.  Judgment upon the award rendered may be entered 
by any court having jurisdiction in the State of Ohio.  If any action or 
proceeding is brought to enforce the decision of the arbitrators, the 
prevailing party shall be entitled to recover its reasonable attorney's fees 
and other costs incident to such action or proceeding.  The provisions of 
this Article 13 shall not affect the right of any party to seek provisional 
legal or equitable remedies. The law of Ohio  shall be applied to any dispute 
under arbitration. The parties warrant and represent that the filing of an 
arbitration demand will not prevent, allow, or excuse the parties from 
meeting their obligations under this Agreement during the time any such 
dispute is being resolved. Day to day business functions will continue 
uninterrupted during the arbitration period.

     Trademark- System, the PAPNET-Registered Trademark- Service and the NSI
     Technology;

          (iii) that each term of this Agreement will be construed, wherever
     reasonable, in a

                                      17

<PAGE>

     manner consistent with the understanding of the term by the parties as

hereto are acting hereunder as independent contractors and not joint 
venturers, and under no circumstances shall any of the employees of one party 
be deemed the employees of the other for any purpose.  This Agreement shall 
not be construed as authority for either party to act for the other party in 
any agency or other capacity, or to make commitments of any kind for the 
account of or on behalf of the other except to the extent and for the 
purposes expressly provided for and set forth herein.

     14.4  ASSIGNMENT; SUBLICENSING.  This Agreement and the licenses herein

that Licensee may assign this Agreement to any corporation which is a 
wholly-owned subsidiary of Licensee without such consent. Neither party may 
pledge or otherwise grant a security interest in this Agreement or the 
licenses granted hereby, but may grant a security interest in any payments to 
which it is entitled hereunder. This Agreement shall be binding upon and 
inure to the benefit of the parties and their respective successors and 
permitted assigns.

     14.5  WAIVER; REMEDIES.  No failure on the part of any party to 
exercise, and no delay in exercising, any right hereunder shall operate as a 
waiver thereof, nor shall any single or partial exercise of any right 
hereunder preclude any other or further exercise thereof or the exercise of 
any other right.  The remedies herein provided are cumulative and not 
exclusive of any remedies provided by law. 

     14.6  SEVERABILITY.  If any provision of this Agreement is determined by

governed by and construed in accordance with the laws of the State of  Ohio 
(without giving effect to principles of conflicts of laws).

                              3753 Howard Hughes Parkway
                                      Suite 200
                               Las Vegas, Nevada 89109


                                   February 1, 1995


To: Each of the Target Entities
    (as identified on Exhibit A annexed hereto)

Gentlemen:

    This letter of intent summarizes the understanding reached in discussions
which have occurred among Cytology West, Inc., a Delaware corporation ("CWI"),
and each of the Licensee Corporations and Licensee Partnerships identified on
EXHIBIT A annexed hereto (collectively, the "Target Entities") concerning a
proposed acquisition (the "Proposed Acquisition") by CWI of the Target Entities.

     1.  PROPOSED ACQUISITION.  CWI will issue shares of its common stock as
the consideration in the Proposed Acquisition, with the specific form and
structure of the Proposed Acquisition (e.g., stock for assets, stock for equity
interests, merger) to be agreed upon by CWI and each of the Target Entities
(collectively, the "Parties") after review of tax, accounting, regulatory,
contract, consent, diligence and other appropriate issues.  An S-4 Registration
Statement will be filed by CWI with, and be declared effective by, the
Securities and Exchange Commission (the "SEC") in connection with the Proposed
Acquisition as required by the Securities Act of 1933, as amended (the "1933
Act"), and applicable state Blue Sky laws.  The common stock of CWI will
concurrently be registered under the Securities Exchange Act of 1934, as amended
(the "1934 Act").  It is contemplated that the common stock of CWI will, upon
declaration by the SEC of the effectiveness of the registrations and the
consummation of the Proposed Acquisition, be traded on NASDAQ.

     2.  VALUATION.  Upon consummation of the Proposed Acquisition, the then
existing equity holders of CWI will then own, and the holders of each of the
Target Entities will receive in exchange for their equity interests In their
respective Target Entity and thereafter own, common stock of CWI in an aggregate
amount for CWI and each Target Entity which reflects the relative values of each
of the Parties immediately prior to the consummation of the Proposed Acquisition
(the "Relative Values").  The Parties have preliminarily determined their
Relative Values by the following formula (the "Relative Valuation Formula"):

         RV   =     LV + AV + WV
                   ---------------
                   TLV + TAV + TWV

         Where:    RV   =    the Relative Value in dollars of a Party;

                   LV   =    the dollar value of a Party's license with
                             Neuromedical Systems, Inc. (an "NSI License"),
                             determined by multiplying $0.81 times the
                             population (based on 1994 census data) of the
                             territory covered by the NSI License, which dollar
                             value in shown in column 3 of the table on EXHIBIT
                             B annexed hereto (the "License Value");
                   AV   =    the dollar value of the sum of the following
                             assets and liabilities of a Party immediately
                             existing prior to the consummation of the Proposed
                             Acquisition and which are in the case of a Target
                             Entity, acquired by CWT upon consummation of the
                             Proposed Acquisition:  (a) the cash of the Party
                             plus (b) the book value of all other assets of the
                             Party other than the NSI License and NSI Warrants
                             (as defined below), if any, and any other
                             intangible assets of the Party, less (c) the
                             amount of any liabilities of the Party (the
                             "Assets Value");
                   WV   =    the dollar value of any warrants to purchase
                             shares of common stock of Neuromedical Systems,
                             Inc. ("NSI") ("NSI Warrants") held by a Party
                             immediately existing prior to the consummation of
                             the Proposed Acquisition and which are in the case
                             of a Target Entity, acquired by CWI upon
                             consummation of the Proposed Acquisition (the
                             "Warrant Value").  The Warrant Value is determined
                             by multiplying (a) the aggregate number of shares
                             of NSI common stock into which the NSI warrants
                             are exercisable by (b) an amount equal to the
                             difference between (i) $2.50, the agreed per share
                             fair market value of NSI common stock (the "NSI
                             Per Share Value,), and (ii) the warrant exercise
                             price for each share of NSI common stock into
                             which the NSI Warrants are exercisable;

                   TLV  =    the total License Values of the Parties, as shown
                             in column 3 of the table on EXHIBIT B;

                   TAV  =    the total Assets Values of the Parties; and

                   TWV  =    the total Warrant Values of the Parties.

    The Parties' preliminary determination of Relative Values is set forth in
column 11 of the table on EXHIBIT B, and assumes for purposes of such
preliminary determination that the represented territory populations are
accurate and that the Warrant Values and Assets Values with respect to each of
the Parties will be as set forth in columns 8 and 9, respectively, of such
table.

    The Definitive Agreements (as hereinafter defined) will get forth the
agreed Assets Value of each of the Parties for purposes of determining the Final
Formula Derived Relative Values (as provided below), which agreed upon Assets
Value shall also be the minimum Assets Value actually acquired by CWI from the
Party at the time of the consummation of the Proposed Acquisition.  The
Definitive Agreements will permit each Target Entity to determine, prior to
consummation of the Proposed Acquisition, whether or not to include any NSI
Warrants held by such Target Entity in the assets to be acquired  by CWI.
However, each Target Entity presently anticipates that it would so include all
of its NSI Warrants.

    The Relative Values of the Target Entities will be determined as of the
consummation of the Proposed Acquisition (and following the determination with
regard to the Assets Values and NSI Warrants to be included in the Proposed
Acquisition) by the Relative Valuation Formula, using the License Values and
the NSI Per Share Value as set forth on EXHIBIT B and the then actual warrant
exercise price in effect for the applicable NSI Warrants (the "Final Formula
Derived Relative Values").

    Prior to the consummation of the Proposed Acquisition, CWI and Papnet of
Ohio, Inc. will retain an investment banking firm acceptable to each of the
parties to render an opinion to CWI and Papnet of Ohio, Inc. that the terms of
the Proposed Acquisition, it based upon the Final Formula Derived Relative
Values, are fair from the standpoint of the equity holders of CWI and Papnet of
Ohio, Inc. (the "Fairness Opinion").  Subject to the rendering of the Fairness
Opinion, the Relative Values for purposes of allocating ownership of the CWI
common stock shall be the Final Formula Derived Relative Values and not the
Final Formula Derived Relative Values, shall be a final and conclusive
determination binding upon all of the parties to the Proposed Acquisition.  If
the Fairness Opinion is not rendered without material qualification, any Party
will be permitted to withdraw from the Proposed Acquisition.

    The Proposed Acquisition will be structured from a tax standpoint so that
(a) the existing equity holders of the Target Entities will not recognize gain
or loss for income tax purposes upon consummation of the Proposed Acquisition
and (b) the consummation of the Proposed Acquisition will not result in the
imposition of any material tax liability on CWI.  From an accounting standpoint,
consideration will be given to structuring the Proposed Acquisition to account
for it as a "pooling of interests."

     3.  CONDITIONS.  The obligation of each of the Parties to consummate the
Proposed Acquisition will be subject to satisfaction of the requirements set
forth in sections 1 and 2 and to the

<PAGE>

February 1, 1995
Page 4


following conditions precedent, in addition to any other conditions contained
herein or in the Definitive Agreements:

         (a)  POST-CLOSING GOVERNANCE OF CWI.  The Certificate of Incorporation
and Bylaws of CWI will be in a form mutually acceptable to the Parties (as
reflected in exhibits to the Definitive Agreements).  The Board of Directors of
CWI an of the Closing will consist of seven persons, and will include Richards,
Dawson, Genberg and Kennedy, and three additional persons chosen one each by
Carolina Cytology, ER Group and Missouri from among Kelley, Petitti, Ferger and
Kinsey.  CWI will attempt to obtain Directors' and Officers' insurance in
amounts and containing coverage acceptable to the Board of Directors of CWI.
Genberg shall have agreed to be employed by and serve as the Chief Executive
officer of CWI on terms and conditions mutually acceptable to Genberg and CWI.

         (b)  MARKET MAKER.  Each of the Parties shall be reasonably assured
that at least one reputable investment banking firm acceptable to each of the
Parties will make a market in CWI common stock upon consummation of the Proposed
Acquisition.  The Ohio Company, McDonald & Company and Advest each has been
deemed acceptable by each of the Parties.

         (c)  NSI MATTERS.  NSI shall have consented to the Proposed
Acquisition and agreed to modify its license agreements with each of the
Parties, effective on or before consummation of the Proposed Acquisition, into
either a single license agreement with CWI (if modified upon consummation of the
Proposed Acquisition) or separate modified license agreements with each of the
Parties (if modified before consummation of the Proposed Acquisition)
(collectively, the "Modified License Agreement").  The Modified License
Agreement shall be acceptable in form and substance to each of the Parties.  The
Parties contemplate that the Modified License Agreement will improve business
relations without materially changing the aggregate economics of the license
agreements presently in effect.

         (d)  DEFINITIVE AGREEMENTS.  All of the Parties shall have entered
into definitive agreements among all of them (the "Definitive Agreements") with
respect to the Proposed Acquisition containing mutually acceptable
representations, warranties, covenants, closing conditions and other provisions.

         (e)  BOARD AND SHAREHOLDER APPROVALS.  The Boards of Directors (or
comparable governing bodies) of each of the Parties shall have approved the
execution and delivery of the Definitive Agreements and the consummation of the
Proposed Acquisition.  In addition, all requisite approvals of the shareholders
(or other equity holders) of each of the Parties shall have been obtained and no
dissenters, rights (or comparable rights) shall have been asserted by any such
shareholder or other such equity holder.

         (f)  ACQUISITION OF ALL TARGET ENTITIES.  The Proposed Acquisition
shall be consummated simultaneously with respect to each of the Target Entities.

         (g)  NSI WARRANTS.  The Parties shall have reached mutual agreement
regarding the timing and method for exercise of the NSI Warrants to be held by
CWI following consummation of the Proposed Acquisition.

     4.  INTERIM PERIOD; EXECUTION OF DEFINITIVE AGREEMENTS.

         (a)  PRELIMINARY NSI MATTERS.  Following execution of this letter of
intent, each of the Parties, through Genberg, Richards and Kinsey, each of whom
is hereby appointed by the Parties for such purposes, shall exercise reasonable
efforts to obtain, prior to February 28, 1995, preliminary consent from NSI to
the Proposed Acquisition and to undertake negotiations with NSI with regard to
the form of Modified License Agreement.

         (b)  DEFINITIVE AGREEMENT.  Upon receipt of the preliminary approval
of NSI described in subsection (a) above, the Parties will use reasonable
efforts to complete their negotiations and due diligence with respect to the
Proposed Acquisition.  Subject to the mutual satisfaction of the Parties with
the results of such due diligence, the Parties will prepare and execute
Definitive Agreements with regard to the Proposed Acquisition, with the
intention of entering into the Definitive Agreements as promptly as practicable.

         (c)  DUE DILIGENCE.  Prior to the execution of Definitive Agreements,
the Parties will complete their review of any and all matters that any of them
deem necessary or appropriate, including, without limitation, all material
contracts, books and records, title to and condition of assets, legal and
regulatory issues, environmental compliance and labor and employment matters.
The Parties recognize that certain financial and non-financial information will
be required of each of them in connection with the contemplated registrations
and agree to provide such information and other cooperation which may he
reasonably requested in connection therewith.

         (d)  CONFIDENTIALITY.  None of the Parties shall disclose to any
person (other than its employees, officers, directors, equity holders and
representatives who need to know such information for purposes of pursuing the
Proposed Acquisition) (i) the fact that discussions or negotiations are taking
place concerning a Proposed Acquisition, (ii) any of the terms, conditions or
other facts with respect to the Proposed Acquisition, including the status
thereof, or (iii) any other non-public information furnished to any of the
Parties pursuant to this letter of intent; provided, however, that Papnet of
Ohio, Inc. may make such disclosures as it determines in good faith are required
to be made under applicable federal and state securities laws.  Prior to
delivery, by any of the Parties to any of the other Parties, of information for
which the delivering Party seeks confidential treatment, the Parties receiving
such information shall, at the request of the delivering

<PAGE>

Page 6


Party, enter into a non-disclosure agreement containing additional terms and
conditions relating to confidentiality.

     5.  COSTS AND EXPENSES.  Certain costs and expenses will be incurred by or
on behalf of some or all of the Parties in connection with the negotiation and
consummation of the Proposed Acquisition, including, without limitation,
accounting, legal, underwriting, fairness opinion and other coats and expenses
(collectively, the "Transaction Expenses").  Each of the Parties does hereby (a)
authorize Genberg, Richards and Kinsey to incur Transaction Expenses on behalf
of the Parties (or any of them) and (b) agree to pay (either directly or by
reimbursement, as directed by Genberg, Richards or Kinsey) its "Pro Rata Share,
(as defined below) of any Transaction Expenses approved in advance of incurrence
by Genberg, Richards or Kinsey in the event that, for any reason, the Proposed
Acquisition is not consummated; provided, however, that in no event shall any
Party be required to bear any Transaction Expenses incurred after it provides
written notice to the other Parties of termination as provided for in Section 6.
For purposes of this section 5, the "Pro Rata Share" of each Party is equal to
its preliminary Relative Value set forth in column 11 of the table on EXHIBIT B.
If the Proposed Acquisition is consummated, those Transaction Expenses which are
reasonably incurred and approved in advance of incurrence by Genberg, Richards
or Kinsey shall be borne by CWI.

     6.  EXPIRATION.  This letter of intent shall expire, and be of no force or
effect, unless fully executed by each of the Target Entities by February  7,
1995.  Any of the Parties may for any reason terminate its proposed
participation in the Proposed Acquisition at any time prior to the execution by
it of the Definitive Agreements by giving written notice thereof to the other
Parties.

     7.  GOVERNING LAW.  This letter of intent shall be governed by and
construed in accordance with the internal laws, and not the laws pertaining to
conflicts of laws, of the State of Nevada.

     8.  COUNTERPARTS.  This latter of intent may be signed in multiple
counterparts, any one of which need not contain the signatures of more than CWI
and one Target Entity, but all such counterparts taken together shall constitute
one and the same agreement.

     9.  INTEGRATION; AMENDMENTS.  This letter of intent sets forth the
complete and entire understanding of the Parties with respect to the subject
matter hereof, and may not be amended except in writing by all of the Parties.

    10.  NON-BINDING NATURE OF LETTER; BINDING PROVISIONS.  Except as
hereinafter provided with respect to the binding nature of certain provisions
hereof, (a) this letter of intent is intended only to express the mutual good
faith intentions of the Parties and is not intended to constitute a binding
agreement, (b) any of the Parties may at any time and in its sole discretion
discontinue discussions concerning the Proposed Acquisition and/or terminate its
proposed participation in the Proposed

Acquisition as provided in section 6 and (c) each of the Parties reserves the
right at any time prior to execution of the Definitive Agreements to refuse to
enter into the Definitive Agreements.  The Parties understand that no contract,
agreement, arrangement or understanding providing for the acquisition (or offer
to acquire) any of the Target Entities or for the purchase (or offer to
purchase) or for voting of any of the equity securities of any of the Target
Entities shall be deemed to exist between or among CWI and any of the Target
Entities or their respective equity holders unless and until each of the Parties
and all other necessary parties have executed fully and delivered mutually
acceptable Definitive Agreements containing such covenants, representations,
warranties, closing conditions and other provisions as the Parties may agree
upon.  Notwithstanding any provision contained in this Section 10 or elsewhere
in this letter of intent to the contrary, upon execution of this letter of
intent by each of the Target Entities pursuant to Section 6, the provisions of
Sections 4(d), 5, 6, 7, 8, 9 and 10 shall represent the binding agreements of
each of the Parties and shall survive any termination of this letter of intent
or the discussions concerning the Proposed Acquisition.

    If this letter of intent accurately sets forth the understanding of the
Parties, please so indicate by executing this original letter of intent and the
enclosed duplicate original letters of intent where provided below and returning
each of them to me.  I will distribute an original fully executed letter of
intent to each of the Target Entities for its files.

                                  Very truly yours,

                                SIDE LETTER AGREEMENT


Re:     Cytology West Inc. Letter of Intent dated February 1, 1995

The parties below have signed a Letter of Intent to effect a combination.  A
deadline of February 28, 1995, is given to Neuromedical Systems, Inc. to
complete negotiations and finalize a new License Agreement for all of the
parties.  It is the intent of the parties to continue to operate under the
non-binding Letter of Intent until such time as any party provides written
notice of withdrawal as provided for in the Letter of Intent that they no longer
are interested in pursuing the merger.  The February 28, 1995, date is put into
the agreement for the sole purpose of providing a deadline against which NSI
will operate.

The parties also agree to give Tom Kelly veto power over any expense to be
incurred prior to the time when a new license agreement is reached.  Any expense
so incurred will have to be approved by the Kinsey, Richards, Genberg committee
and also by Tom Kelly before they are incurred.


APPROVED, ACCEPTED AND AGREED:

                                VOTING AGREEMENT

     This Voting Agreement, dated as of July 5, 1996, by and among Papnet of 
Ohio, Inc., an Ohio corporation (the "Company"), Cytology Indiana, Inc., an 
Ohio corporation ("CIN"), Indiana Cytology Review Company, an Ohio 
corporation ("INC"), ER Group, Inc., an Ohio corporation ("ERG"), CCWP 
Partners, Inc., an Ohio corporation ("CCWP") and Carolina Cytology, Inc., an 
Ohio corporation ("CCI") (the Company, CIN, INC, ERG, CCWP and CCI are 
hereinafter collectively referred to as the "Constituent Corporations") and 
each of the individual shareholders of the Constituent Corporations executing 
this Agreement ("Shareholders").

                                    RECITALS

     A.   The Constituent Corporations have agreed to a merger in which the 
Company will be the surviving corporation (the "Merger"), pursuant to an 
Agreement and Plan of  Merger dated as of July 5, 1996 (the "Merger 
Agreement").

     B.   The persons executing this Agreement as Shareholders own 
substantial blocks of voting shares in one or more of the Constituent 
Corporations ("Shares") and were parties to a Voting Agreement, dated May 31, 
1996, which has been terminated.

     C.   In order to facilitate the Merger and its approval by the other 
shareholders of the Constituent Corporations, the Shareholders have agreed to 
vote their shares in favor of the Merger.

                             STATEMENT OF AGREEMENT

     In consideration of their mutual promises therein, and as additional 
consideration and inducement to the Constituent Corporations to perform their 
obligations under the Merger Agreement, the parties agree as follows:

     1.   VOTING AGREEMENT.  Each Shareholder severally agrees and covenants 
with the Constituent Corporations and each of the other Shareholders that at 
any meeting of the shareholders of any of the Constituent Corporations called 
to vote upon the Merger and the Merger Agreement or at any adjournment 
thereof or in any other circumstance upon which a vote, consent or other 
approval with respect to the Merger and the Merger Agreement is sought, such 
Shareholder shall vote (or cause to be voted) such Shareholder's Shares in 
favor of the Merger, the approval of the Merger Agreement and each of the 
other transactions contemplated by the Merger Agreement.

     2.   COVENANTS.  Each Shareholder severally agrees and covenants with 
the Constituent Corporations and each of the other Shareholders that such 
Shareholder shall not (a) grant any proxy, power-of-attorney or other 
authorization in or with respect to his Shares, except to vote such Shares as 
provided in this Agreement, or (b) deposit such Shares into a voting trust or 
enter into a voting agreement or arrangement with respect to such Shares.

<PAGE>

     3.   GRANT OF IRREVOCABLE PROXY.  Each Shareholder irrevocably grants 
to, and appoints John P. Kennedy and Cecil J. Pettiti, and each of them 
individually, such Shareholder's proxy and attorney-in-fact (with full power 
of substitution), for and in the name, place and stead of such Shareholder, 
to vote such Shareholder's Shares in each Constituent Corporation, or grant a 
consent or approval with respect to such Shares, in favor of the Merger, the 
approval of the Merger Agreement and each of the other transactions 
contemplated by the Merger Agreement, and hereby revokes any proxies 
heretofore given.

     4.   SECURITIES LAWS.  Each of the obligations of Shareholder under this 
Agreement is conditioned upon the filing and effectiveness of a registration 
statement on Form S-4 under the Securities Act of 1933, as amended, covering 
the offering and sale of the Surviving Corporation Shares (as such term is 
defined in the Merger Agreement) to be issued in the Merger.

     5.   TERMINATION.  This Agreement, and all rights and obligations of the 
parties hereunder, shall terminate upon the first to occur of the Effective 
Time (as such term is defined in the Merger Agreement) or the date upon which 
the Merger Agreement is terminated in accordance with its terms.

     6.   REMEDIES.  Each Shareholder agrees that irreparable damage would 
occur and that the Constituent Corporations and the other Shareholders would 
not have an adequate remedy at law in the event that such Shareholder failed 
to perform his obligations hereunder or otherwise breaches this Agreement.  
It is accordingly agreed that any party seeking to enforce this Agreement 
shall be entitled to an injunction or injunctions to prevent breaches by any 
Shareholder and to enforce specifically the terms and provisions of this 
Agreement in any state or federal court located in Franklin County, Ohio, 
this being in addition to any other remedy which may be available at law or 
in equity.  In addition, each of the parties hereto (a) consents to submit to 
the personal jurisdiction of any state or federal court located in Franklin 
County in the event any dispute arises out of this Agreement or any of the 
transactions contemplated hereby; (b) agrees that such party will not attempt 
to deny or defeat such personal jurisdiction by motion or other request;  and 
(c) agrees that such party will not bring any action relating to this 
Agreement or the transactions contemplated hereby in any court other than a 
state or federal court located in Franklin County, Ohio.

          IN WITNESS WHEREOF, the parties have executed this Agreement as of 
the date first set forth above.

                                 LOAN AGREEMENT

     This Agreement, dated as of July 5, 1996, by and among Papnet of Ohio, 
Inc., an Ohio corporation ("Papnet"),  Cytology Indiana, Inc., an Ohio 
corporation ("CIN"), Indiana Cytology Review Company, an Ohio corporation 
("INC"), ER Group, Inc., an Ohio corporation ("ERG"), CCWP Partners, Inc., an 
Ohio corporation ("CCWP") and Carolina Cytology, Inc., an Ohio corporation 
("CCI").  CIN, INC, ERG, CCWP and CCI are hereinafter sometimes collectively 
referred to as the "Borrowers" and individually as a "Borrower." 

                                    RECITALS

     A.   Papnet and the Borrowers were parties to a Loan Agreement, dated as 
of March 14, 1996, which has been terminated (the "Initial Loan Agreement"). 
Papnet made advances to the Borrowers under the Initial Loan Agreement in the 
amounts set forth opposite their respective names on Exhibit A attached 
hereto and incorporated herein (the "Initial Advances").

     B.   Pursuant to an Agreement and Plan of Merger of even date (the 
"Merger Agreement"), the parties have agreed that CIN, INC, ERG, CCWP and CCI 
will merge with and into Papnet (the "Merger").  Certain capitalized terms 
not otherwise defined herein shall have the meanings as defined in the Merger 
Agreement.

     C.   Pending the effectiveness of the Merger, Papnet has agreed, subject 
to the terms and conditions contained in this Agreement, to make certain 
advances (hereinafter called an "Advance" or "Advances") on behalf of the 
Borrowers to pay certain expenses of the Merger and to fund business 
operations of the Borrowers.

     D.   The parties wish to set forth in this Agreement the terms and 
conditions on which the Initial Advances will be repaid and the Advances made 
under this Agreement will be made and repaid.

                             STATEMENT OF AGREEMENT

     1.   ADVANCES OF MERGER AND OFFERING EXPENSES.  Through the Effective 
Date, Papnet agrees to make such Advances on behalf of each Borrower as are 
necessary to pay such Borrower's pro-rata share of expenses incurred in 
connection with the Merger.  Papnet may incur and pay legal, accounting, 
printing, filing, travel, meeting and other expenses in connection with the 
Merger, or may pay such expenses reasonably incurred by any Borrower, and 
shall allocate a pro-rata share of all of such expenses to each Borrower in 
the proportion provided in the Merger Agreement.  Such amounts will be 
considered an Advance to each Borrower hereunder, in the proportion provided 
in the Merger Agreement, as of the date that such amounts are actually paid 
by Papnet.  Papnet shall keep adequate books and records of such expenses 
which shall be available for inspection by any Borrower during normal 
business hours upon reasonable prior notice. 

     2.   ADVANCES OF OPERATING EXPENSES.   Through the Effective Date, 
Papnet agrees to make such Advances to or on behalf of each Borrower 
individually as are necessary to pay

<PAGE>

reasonable expenses of ordinary business operations of such Borrower, as 
approved by Papnet.  Each such Advance shall be made to or on behalf of a 
Borrower upon receipt of the Borrower's application therefor and disbursement 
instructions, which shall be in a form as Papnet shall reasonably prescribe, 
and will be considered an Advance to such Borrower hereunder.  The 
reasonableness of any expenses for which Advances are requested, and the 
amount of any Advance, shall be determined by Papnet in its sole discretion.

     3.   REPAYMENT.  The total amount of the Initial Advances and the 
Advances hereunder to or on behalf of a Borrower shall be repaid, with 
interest at the rate of seven percent (7.00%) per annum, sixty days after the 
Termination Date, as defined in Section 5.  Each Borrower may pay the unpaid 
principal amount of any Advance made to or on behalf of it in whole or in 
part at any time and from time to time.  Each such payment of principal may 
be made without the payment of accrued and unpaid interest thereon.   
Interest shall be calculated on the basis of a 360-day year for the actual 
number of days the principal balance is unpaid. After maturity, whether such 
maturity occurs by lapse of time or acceleration, interest on the unpaid 
balance of any Initial Advances Advances (and interest thereon accrued 
through maturity) shall accrue at the rate of twenty four percent (24.00%) 
per annum until all Advances and accrued interest are repaid in full. The 
Initial Advances and Advances to each Borrower shall be evidenced by one or 
more promissory notes in the form of Exhibit B to this Agreement, or by one 
or more notes subsequently executed in substitution therefor.  

     4    STATEMENTS.  On the 25th day of each month during the term of this 
Agreement, Papnet shall deliver to each Borrower a statement showing, for the 
immediately preceding month, all Advances made to or on behalf of such 
Borrower, all payments or partial payments of the principal amount of 
Advances by the Borrower, the accrued and unpaid interest on the Advances, if 
any, and such other information as may be necessary or appropriate.   Each 
Borrower hereto agrees that it will immediately notify Papnet of any error in 
any monthly statement delivered to it, and the failure to do so within five 
(5) business days shall be deemed to be a waiver of any claimed error.  
Papnet's allocation of Advances to any Borrower shall be presumed correct, 
and in the event of any dispute concerning the amount, manner of calculation 
or allocation of any Advance as shown on any statement, the party disputing 
the statement shall have the burden of demonstrating any error.

     5.   TERMINATION.  Papnet's right and ability to make Advances hereunder 
shall terminate upon a date (the "Termination Date") which is the earlier to 
occur of (a) the closing of the Merger, or (b) the termination of the Merger 
Agreement as provided in Article VIII thereof.

     6.   SECURITY.  As security for the Initial Advances and Advances to or 
on behalf of  it hereunder, each Borrower shall pledge to Papnet  all of the 
common shares of Neuromedical Systems, Inc. currently owned by it, pursuant 
to the terms of a Security Agreement in the form attached hereto as Exhibit C.

     7.   REPRESENTATIONS AND WARRANTIES OF BORROWERS.  In addition to the 
representations and warranties of each Borrower contained in the Merger 
Agreement, upon which each Borrower agrees

                                      2

<PAGE>

that Papnet may rely for purposes of this Agreement, each Borrower represents 
and warrants to Papnet that:

     (a)  The Board of Directors of the Borrower has duly authorized the 
execution and delivery of this Agreement and of the documents contemplated 
herein, and this Agreement and such documents constitute valid and binding 
obligations of the Borrower enforceable in accordance with their terms, 
subject to the Enforceability Exceptions.

     (b)  The execution of this Agreement and related  documents and the 
compliance by the Borrower with all the provisions thereof:

          (i)  are within the corporate powers of the Borrower; and

          (ii) will not conflict with, result in any breach in any of the
               provisions of, constitute a default under, or result in the
               creation of any lien or encumbrance upon any property of the
               Borrower under the provisions of, any agreement, charter
               instrument, bylaw, or other instrument to which the Borrower is a
               party or by which it may be bound.

     8.   EVENTS OF DEFAULT.  An "Event of Default" with respect to a 
Borrower shall exist if any of the following occurs and is continuing:

     (a)  the Borrower fails to pay any amount hereunder when due, or fails 
to perform or observe any covenant contained in Article VI of the Merger 
Agreement;

     (b)  any warranty, representation or other statement by or on behalf of 
the Borrower contained in this Agreement, the Merger Agreement, or in any 
instrument furnished in compliance with or in reference to this Agreement is 
false or misleading in any material respect;

     (c)  the Borrower becomes insolvent or bankrupt, or makes an assignment 
for the benefit of creditors, or consents to the appointment of a trustee, 
receiver or liquidator; or

     (d)  bankruptcy, reorganization, arrangement, insolvency or liquidation 
proceedings are instituted by or against the Borrower.

     9.   DEFAULT REMEDIES.

     (a)  ACCELERATION.  If an Event of Default exists with respect to a 
Borrower, Papnet may immediately exercise any right, power or remedy  
permitted to it by law, and shall have, in particular, without limiting the 
generality of the foregoing, the right to declare the entire principal and 
all interest accrued on all Advances then outstanding to or on behalf of such 
Borrower pursuant to this Agreement to be forthwith due and payable, without 
any presentment, demand, protest or other notice of any kind, all of which 
are hereby expressly waived by each Borrower.

                                      3

<PAGE>

     (b)  NONWAIVER.  No course of dealing on the part of Papnet nor any 
delay or failure on the part of Papnet to exercise any right shall operate as 
a waiver of such right or otherwise prejudice Papnet's rights, powers and 
remedies.

     10.  MISCELLANEOUS.

     (a)  NOTICES.  All communications under this Agreement  shall be in 
writing and shall be mailed by first class mail, postage prepaid.  Any notice 
so addressed and mailed shall be deemed given when so mailed.

     (b)  SUCCESSORS AND ASSIGNS.  This Agreement shall inure to the benefit 
of and be binding upon the heirs, successors and assigns of each of the 
parties.

     (c)  AMENDMENT AND WAIVER. This Agreement may be amended, and the 
observance of any term of this Agreement may be waived, with (and only with) 
the written consent of the parties hereto. 

     (d)  DUPLICATE ORIGINALS.     Duplicate originals of this Agreement may 
be signed by the parties, each of which shall be an original but all of which 
together shall constitute one and the same instrument.

     (e)  GOVERNING LAW.  This Agreement shall be governed by and construed 
in accordance with the laws of the State of Ohio applicable to contracts made

                                                                 Columbus, Ohio

     FOR VALUE RECEIVED, the undersigned promises to pay to the order of 
PAPNET OF OHIO, INC. (hereinafter called the "Lender," which term shall 
include any holder hereof) at such place as the Lender may designate or, in 
the absence of such designation, at any of the Lender's offices, the sum of 
$                or so much of such sum as shall have been advanced by the 
Lender at any time and not hereafter repaid (hereinafter referred to as 
"Advances") pursuant to the Loan Agreement of even date (the "Agreement") 
together with interest provided and payable at the time(s) and in the 
manner(s) provided in the Agreement.  Each such Advance shall be made to the 
undersigned upon receipt by the Lender of the undersigned's application 
therefor and disbursement instructions, which shall be in such form as the 
Lender shall from time to time reasonably prescribe.  The Lender shall be 
entitled to rely on any oral or telephonic communication requesting an 
Advance and/or providing disbursement instructions hereunder, which shall be 
received by it in good faith from anyone reasonably believed by the Lender to 
be the undersigned, or the undersigned's authorized agent.  Each request for 
an Advance shall constitute a warranty and representation by the undersigned 
that no event of default hereunder, under the Agreement, or under any related 
loan documents has occurred and is continuing and that no event or 
circumstance which would constitute such an event of default, but for the 
requirement that notice be given or time elapse or both, has occurred and is 
continuing.  The undersigned agrees that all Advances made by the Lender will 
be evidenced by entries made by the Lender into records maintained by the 
Lender.  The undersigned further agrees that the sum or sums shown such 
records shall be rebuttably presumptive evidence of the amount of the 
Advances and of the amount of any accrued interest.  

INTEREST

     Interest will accrue on the unpaid balance of the Advances until paid at 
the rate of 7% per annum.  Upon maturity, whether by acceleration or 
otherwise, interest will accrue on the unpaid balance of the Advances and 
unpaid interest, if any, until paid at the rate of 24% per annum.

     All interest shall be calculated on the basis of a 360 day year for the 
actual number of days the Advances or any part thereof remain unpaid.  There 
shall be no penalty for prepayment.

MANNER OF PAYMENT

     The Advances and accrued interest thereon shall be due and payable sixty 
days after the Termination Date, as defined in the Agreement, and at 
maturity, whether by acceleration or otherwise.


<PAGE>

SECURITY

     The obligations of the undersigned hereunder are secured by a Security 
Agreement of even date, granting Lender a security interest in certain 
property of the undersigned (the "Collateral").   The Lender shall not be 
bound to take any steps necessary to preserve any rights in the Collateral 
against prior parties.  If any obligation evidenced by this Note is not paid 
when due, the Lender may, at its option, demand, sue for, collect or make any 
compromise or settlement it deems desirable with reference to the Collateral, 
and shall have the rights of a secured party under the laws of the State of 
Ohio, and the undersigned shall be liable for any deficiency.

DEFAULT

     Upon the occurrence of any of the events of default set forth in the 
Agreement, then the Lender may, at its option, without notice or demand, 
accelerate the maturity of the obligations evidenced hereby, which 
obligations shall become immediately due and payable.  In the event the 
Lender shall institute any action for the enforcement or collection of the 
obligations evidenced hereby, the undersigned agrees to pay all costs and 
expenses of such action, including reasonable attorneys' fees, to the extent 
permitted by law.

GENERAL PROVISIONS

     The undersigned, and any indorser, surety, or guarantor, hereby 
severally waive presentment, notice of dishonor, protest, notice of protest, 
and diligence in bringing suit against any of them, and consent that, without 
discharging any of them, the time of payment may be extended an unlimited 
number of times before or after maturity without notice.  The Lender shall 
not be required to pursue the undersigned, including any guarantor, or to 
exercise any rights against any Collateral herefor before exercising any 
other such rights.

     The obligations evidenced hereby may from time to time be evidenced by 
another note or notes given in substitution, renewal or extension hereof.  
Any security interest which secures the obligations evidenced hereby shall 
remain in full force and effect notwithstanding any such substitution, 
renewal, or extension.

     The captions used herein are for references only and shall not be deemed 
a part of this Note.  If any of the terms or provisions of this Note shall be 
deemed unenforceable, the enforceability of the remaining terms and 
provisions shall not be affected.  This Note shall be governed by and 
construed in accordance with the laws of the State of Ohio.

WAIVER OF RIGHT TO TRIAL BY JURY

     THE UNDERSIGNED ACKNOWLEDGES THAT, AS TO ANY AND ALL DISPUTES THAT MAY
ARISE BETWEEN THE UNDERSIGNED AND THE LENDER, THE COMMERCIAL NATURE OF THE
TRANSACTION OUT OF WHICH THIS NOTE ARISES
                                       2

<PAGE>

WOULD MAKE ANY SUCH DISPUTE UNSUITABLE FOR TRIAL BY JURY.  ACCORDINGLY, THE 
UNDERSIGNED HEREBY WAIVES ANY RIGHT TO TRIAL BY JURY AS TO ANY AND ALL 
DISPUTES THAT MAY ARISE RELATING TO THIS NOTE OR TO ANY OF THE OTHER 
INSTRUMENTS OR DOCUMENTS EXECUTED IN CONNECTION HEREWITH.

WARRANT OF ATTORNEY

     The undersigned authorizes any attorney at law to appear in any Court of 
Record in the State of Ohio or in any state or territory of the United States 
after the above indebtedness becomes due, whether by acceleration or 
otherwise, to waive the issuing and service of process, and to confess 
judgment against undersigned in favor of the Lender for the amount then 
appearing due together with costs of suit, and  thereupon to waive all errors 
and all rights of appeal and stays of execution.  The attorney at law 
authorized hereby to appear for the undersigned may be an attorney at law 
representing the Lender, and the undersigned hereby expressly waives any 
conflict of interest that may exist by virtue of such representation.

WARNING-BY SIGNING THIS PAPER YOU GIVE UP YOUR RIGHT TO NOTICE AND COURT 
TRIAL. IF YOU DO NOT PAY ON TIME A COURT JUDGMENT MAY BE TAKEN AGAINST YOU 
WITHOUT YOUR PRIOR KNOWLEDGE AND THE POWERS OF A COURT CAN BE USED TO COLLECT 
FROM YOU REGARDLESS OF ANY CLAIMS YOU MAY HAVE AGAINST THE CREDITOR WHETHER 
FOR RETURNED GOODS, FAULTY GOODS, FAILURE ON HIS PART TO COMPLY WITH THE 
AGREEMENT, OR ANY OTHER CAUSE.

                               CERTIFICATED STOCK

     The undersigned (hereinafter called "Debtor" whether one or more), for 
valuable consideration, the receipt and sufficiency of which are hereby 
acknowledged, hereby grants, pledges and assigns to Papnet of Ohio, Inc. 
(hereinafter called "Lender"), a security interest in the following stock, 
whether Debtor's interest therein be now owned or existing or hereafter 
arising or acquired, together with all substitutions, replacements, 
exchanges, reissues and additions therefor or thereto, all books and records 
relating thereto, all dividends and distributions arising therefrom, payable 
thereon or distributed in respect thereto, whether in cash, property, stock 
or otherwise, and whether now or hereafter declared, paid or made, and 
together with the right to receive and receipt therefor, and all cash and 
non-cash proceeds thereof including, but not limited to, notes, drafts, 
checks, instruments and deposit and money market accounts:

        Common Shares,
$.0001 par value              Neuromedical Systems, Inc.

</TABLE>

(all of the foregoing hereinafter sometimes called the "Collateral").  Except 
as otherwise provided in this agreement, Debtor shall have the right to 
receive all dividends arising with respect to the Collateral paid in cash or 
in other property, but Debtor shall have no right to receive any dividend in 
respect of the Collateral paid in stock of the Issuer or in the stock of 
corporations other than the Issuer or paid out of the proceeds of the sale or 
condemnation of any property of the Issuer or upon or in the course of 
dissolution or liquidation (whether partial or otherwise) or winding up of 
the Issuer or which in any way shall be chargeable to or payable out of 
capital, capital surplus or paid in surplus.  Debtor shall not have the right 
to receive any dividends arising with respect to the Collateral if a default 
exists in the observance and performance of any of the terms of this 
agreement, or of any of the Obligations, or if ownership of the Collateral 
has been registered in the name of Lender or any nominee of Lender or any 
sub-agent appointed by Lender pursuant to paragraph 7 of this agreement, and 
all dividends arising under such circumstances shall be paid to Lender and, 
at Lender's option, may be applied to the Obligations in such order as Lender 
may elect or be held as security therefor.

     The security interest hereby granted is to secure the prompt and full
payment and complete performance of all Obligations of Debtor to Lender.  The
word "Obligations" is used in its most comprehensive sense and includes, without
limitation, all indebtedness, debts and liabilities (including principal,
interest, late charges, collection costs, attorneys' fees to the extent
permitted by law, and the like) of Debtor to Lender, whether now existing or
hereafter arising, either created by Debtor alone or together with another or
others, primary or secondary, secured or unsecured,

<PAGE>

absolute or contingent, liquidated or unliquidated, direct or indirect, 
whether evidenced by note, draft, application for letter of credit or 
otherwise, and any and all renewals of or substitutes therefor.  The word 
"Obligations" shall include, BUT NOT BE LIMITED TO, all indebtedness owed by 
Debtor to Lender by reason of credit extended or to be extended to Debtor 
pursuant to a Loan Agreement of even date and related documents.

     It is Debtor's express intention that this agreement and the continuing 
security interest granted hereby, in addition to covering all present 
Obligations of Debtor to Lender, shall extend to all future Obligations of 
Debtor to Lender, whether or not such Obligations are reduced or entirely 
extinguished and thereafter increased or reincurred, whether or not such 
Obligations are related to the indebtedness identified above by class, type 
or kind and whether or not such Obligations are specifically contemplated by 
Debtor and Lender as of the date hereof.  The absence of any reference to 
this agreement in any documents, instruments or agreements evidencing or 
relating to any Obligation secured hereby shall not limit or be construed to 
limit the scope or applicability of this agreement.

      1.  GENERAL COVENANTS.  Debtor represents, warrants and covenants as
follows:

          (a)  Unless Lender compels registration of ownership of the 
Collateral in the name of Lender or any nominee of Lender or any sub-agent 
appointed by Lender pursuant to paragraph 7 of this agreement, Debtor is and 
shall remain the sole owner and registered holder of the Collateral.

          (b)  Except for the security interest granted hereby, the 
Collateral is and shall remain free from any and all security interests, 
liens, encumbrances, claims and interests.

          (c)  The Issuer is duly organized, validly existing and is in good 
standing, and each share of stock comprising the Collateral is or, upon 
delivery to Lender shall be, duly authorized, authenticated, issued and 
delivered and enforceable in accordance with its terms and not in default.

          (d)  Each share of stock comprising the Collateral is fully paid 
and nonassessable and, except as otherwise indicated in the certificates 
representing the shares, is transferable in its present form upon delivery 
without restriction or limitation on the books and records of its Issuer.

          (e)  Debtor shall, at Debtor's expense, perform, do, make, procure, 
execute and deliver all acts, things, writings and other assurances as Lender 
may at any time request or require to protect, assure or enforce Lender's 
interests, rights and remedies created by, provided in or emanating from this 
agreement.

          (f)  Debtor shall not create, permit or suffer to exist, and shall 
take such action as is necessary to remove, any claim to or interest in or 
lien or encumbrance upon the Collateral, other than the security interest 
granted hereby, and shall defend the right, title and interest of Lender in 
and to the Collateral against all claims and demands of all persons and 
entities at any time claiming the same or any interest therein.

                                     -2-

<PAGE>

          (g)  Subject to any limitation stated therein or in connection 
therewith, all information furnished by Debtor concerning the Collateral or 
otherwise in connection with the Obligations, is or shall be at the time the 
same is furnished, accurate, correct and complete in all material respects.

      2.  VOTING.  With respect to any Collateral not registered in the name 
of Lender or Lender's nominee or sub-agent pursuant to paragraph 7 of this 
agreement, during the term of this agreement, and so long as (i) there is no 
default in the observance and performance of any of the terms of this 
agreement or of any of the Obligations, and (ii) Lender has not notified 
Debtor of Lender's election to exercise any voting rights relating to the 
Collateral, Debtor shall have the right to exercise such voting rights on all 
corporate questions.

      3.  SUBSTITUTED AND ADDITIONAL SECURITIES.  If during the term of this 
agreement any stock dividend, exchange, conversion, reclassification, 
readjustment or other change is paid, declared or made with respect to the 
Collateral, all new, substituted and additional securities issued in respect 
to the Collateral shall be deemed pledged to Lender under the terms of this 
agreement in the same manner as the Collateral originally pledged hereunder.

      4.  WARRANTS AND OPTIONS.  If during the term of this agreement 
subscription warrants or options are issued in connection with the Collateral 
or any other securities at the time pledged to Lender hereunder, such 
warrants and options shall be immediately assigned by Debtor to Lender, and 
all new securities acquired by Debtor in connection therewith shall be 
immediately assigned to Lender under the terms of this agreement in the same 
manner as the Collateral originally pledged hereunder.

      5.  PRESERVATION AND DISPOSITION OF COLLATERAL.

          (a)  Debtor shall advise Lender promptly, in writing and in 
reasonable detail, (i) of any material encumbrance upon or claim asserted 
against any of the Collateral; and (ii) of the occurrence of any event that 
would have a material effect upon the aggregate value of the Collateral or 
upon the security interest of Lender.

          (b)  Debtor shall pay promptly when due all taxes, assessments, 
charges or levies upon the Collateral or in respect to the income or profits 
therefrom or the transfer or registration thereof.

          (c)  At its option, Lender may discharge taxes, liens, security 
interests or other encumbrances at any time levied or placed on or arising in 
connection with the Collateral.  Debtor agrees to reimburse Lender upon 
demand for any payment made or any expense incurred (including reasonable 
attorneys' fees to the extent permitted by law) by Lender pursuant to the 
foregoing authorization.  Should Debtor fail to pay said sum to Lender upon 
demand, interest shall accrue thereon, from the date of demand until paid in 
full, at the highest rate set forth in any document or instrument evidencing 
any of the Obligations.

                                      -3-               

<PAGE>

      6.  EXTENSIONS AND COMPROMISES.  With respect to any Collateral pledged 
to Lender as security for the Obligations, Debtor assents to all extensions 
or postponements of the time of payment thereof or any other indulgence in 
connection therewith, to each substitution, exchange or release of 
Collateral, to the addition or release of any party primarily or secondarily 
liable, to the acceptance of partial payments thereon and to the settlement, 
compromise or adjustment thereof, all in such manner and at such time or 
times as Lender may deem advisable.  Lender shall have no duty as to the 
collection or protection of Collateral or any income therefrom, nor as to the 
preservation of any right pertaining thereto, beyond the safe custody of 
Collateral in the possession of Lender.

      7.  LENDER'S APPOINTMENT AS ATTORNEY-IN-FACT.  Debtor hereby 
irrevocably constitutes and appoints Lender and any officer or agent thereof, 
with full power of substitution, as Debtor's true and lawful attorney-in-fact 
with full irrevocable power and authority in the place and stead of Debtor 
and in the name of Debtor or in Lender's own name, from time to time in 
Lender's discretion, for the purpose of carrying out the terms of this 
agreement, to take any and all appropriate action and to execute any and all 
documents and instruments that may be necessary or desirable to accomplish 
the purpose of this agreement.

          Debtor hereby ratifies all that said attorneys shall lawfully do or 
cause to be done by virtue hereof.  This power of attorney is a power coupled 
with an interest and shall be irrevocable.

          Lender may, in its discretion, register ownership of any of the 
Collateral in the name of Lender or any nominee of Lender or any sub-agent 
appointed by Lender, or may designate a nominee or sub-agent for the purpose 
of retaining physical possession of the instruments, certificates and similar 
writings representing any of the Collateral, indorsed or assigned in blank or 
in favor of Lender or Lender's nominee or sub-agent.

          Debtor hereby consents and agrees that the Issuer or any obligor in 
respect of the Collateral or any registrar or transfer agent or trustee for 
any of the Collateral shall be entitled to accept the provisions hereof as 
conclusive evidence of the rights of Lender to effect any transfer pursuant 
to this paragraph 7, notwithstanding any other notice or direction to the 
contrary heretofore or hereafter given.

          The powers conferred upon Lender hereunder are solely to protect 
its interests in the Collateral and shall not impose any duty upon Lender to 
exercise any such powers.  Lender shall be accountable only for amounts that 
Lender actually receives as a result of the exercise of such powers and 
neither Lender nor any of its officers, directors, employees or agents shall 
be responsible to Debtor for any act or failure to act, except for Lender's 
own gross negligence or willful misconduct.

      8.  DEFAULT.  If any event of default in the payment  of any of the 
Obligations or in the performance of any of the terms, conditions, or 
provisions of any instrument or document evidencing the Obligations secured 
by this agreement or in the performance of any covenant contained herein 
shall occur and be continuing; or if any warranty, representation or 
statement made or furnished to Lender by Debtor proves to have been false in 
any material respect when made or furnished; or if

                                      -4-

Lender shall for any reason deem itself insecure as to the prospect of 
payment of any of the Obligations:

          (a)  Lender may, at its option and without notice, declare the 
unpaid balance of any or all of the Obligations immediately due and payable 
and this agreement and any or all of the Obligations in default.

          (b)  All payments received by Debtor under or in connection with 
any of the Collateral shall be held by Debtor in trust for Lender, shall be 
segregated from other funds of Debtor and shall forthwith upon receipt by 
Debtor be turned over to Lender in the same form as received by Debtor (duly 
indorsed by Debtor to Lender, if required).  Any and all such payments so 
received by Lender (whether from Debtor or otherwise) may, in the sole 
discretion of Lender, be held by Lender as collateral security for, and/or 
then or at any time thereafter be applied in whole or in part by Lender 
against, all or any part of the Obligations in such order as Lender may 
elect.  Any balance of such payments held by Lender and remaining after 
payment in full of all the Obligations shall be paid over to Debtor or to 
whomsoever may be lawfully entitled to receive the same.  Nothing set forth 
in this subparagraph (b) shall authorize or be construed to authorize Debtor 
to sell or otherwise dispose of any Collateral.

          (c)  Lender and its nominees and sub-agents shall have the rights 
and remedies of a secured party under this agreement, under any other 
instrument or agreement securing, evidencing or relating to the Obligations 
and under the law of the State of Ohio.  To the extent permitted by 
applicable law, Debtor waives all claims, damages and demands against Lender 
arising out of the repossession, retention, sale or disposition of the 
Collateral.  Debtor agrees that Lender need not give more than seven (7) 
days' notice (which notification shall be deemed given when mailed, postage 
prepaid, addressed to Debtor at Debtor's address set forth at the beginning 
of this agreement, or when telecopied or telegraphed to that address or when 
telephoned or otherwise communicated orally to Debtor or any agent of Debtor 
at that address), if any, of the time and place of any public sale or of the 
time after which a private sale may take place and that such notice is 
reasonable notification of such matters.  Debtor shall remain liable for any 
deficiency if the proceeds of any sale or disposition of the Collateral are 
insufficient to pay all amounts to which Lender is entitled. Debtor shall 
also be liable for the costs of collecting any of the Obligations or 
otherwise enforcing the terms thereof or of this agreement including 
reasonable attorneys' fees to the extent permitted by law.

      9.  GENERAL.  Any provision of this agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.  Lender shall not be deemed to have waived any of its rights
hereunder or under any other agreement, instrument or paper signed by Debtor
unless such waiver be in writing and signed by Lender.  No delay or omission on
the part of Lender in exercising any right shall operate as a waiver of such
right or any other right.  All of Lender's rights and remedies, whether

                                      -5-                            

<PAGE>

evidenced hereby or by any other agreement, instrument or paper, shall be 
cumulative and may be exercised singularly or concurrently.  Any written 
demand upon or written notice to Debtor shall be effective when deposited in 
the mails addressed to Debtor at the address shown at the beginning of this 
agreement. This agreement and all rights and obligations hereunder, including 
matters of construction, validity and performance, shall be governed by the 
law of the State of Ohio.  The provisions hereof shall, as the case may 
require, bind or inure to the benefit of, the respective heirs, successors, 
legal representatives and assigns of Debtor and Lender.

     IN WITNESS WHEREOF, Debtor has signed this agreement this       day of 
March, 1996.

                                     DEBTOR:

<PAGE>

                                    LOAN AGREEMENT

    This Agreement, dated as of March 14, 1996, by and among Papnet of Ohio,
Inc., an Ohio corporation ("Papnet"),  Cytology West, Inc., a Delaware
corporation ("CWI"), Cytology Indiana, Inc., an Ohio corporation ("CIN"),
Indiana Cytology Review Corporation, an Ohio corporation ("INC"), ER Group,
Inc., an Ohio corporation ("ERG"), CCWP Partners, Inc., an Ohio corporation
("CCWP"), Carolina Cytology, Inc., an Ohio corporation ("CCI"), and Papnet Utah,
Inc., a Nevada corporation ("PUI").  CWI, CIN, INC, ERG, CCWP, CCI and PUI are
hereinafter sometimes collectively referred to as the "Borrowers" and
individually as a "Borrower."

                                       RECITALS

    A.   Pursuant to an Agreement and Plan of Merger of even date (the "Merger
Agreement"), the parties have agreed that Papnet, CIN, INC, ERG, CCWP, CCI and
PUI will merge with and into CWI (the "Merger").  Certain capitalized terms not
otherwise defined herein shall have the meanings as defined in the Merger
Agreement.

    B.   Pending the effectiveness of the Merger, Papnet has agreed, subject to
the terms and conditions contained in this Agreement, to make certain advances
(hereinafter called an "Advance" or "Advances") on behalf of the Borrowers to
pay certain expenses of the Merger and an anticipated Initial Public Offering by
the Surviving Corporation, and to fund business operations of the Borrowers.

    C.   The parties wish to set forth in this Agreement the terms and
conditions on which such Advances will be made and repaid.

                                STATEMENT OF AGREEMENT

    1.   ADVANCES OF MERGER AND OFFERING EXPENSES.  Through the Effective Date,
Papnet agrees to make such Advances on behalf of each Borrower as are necessary
to pay such Borrower's pro-rata share of expenses incurred in connection with
the Merger or the Initial Public Offering.  Papnet may incur and pay legal,
accounting, printing, filing, travel, meeting and other expenses in connection
with the Merger or the Initial Public Offering, or may pay such expenses
reasonably incurred by any Borrower, and shall allocate a pro-rata share of all
of such expenses to each Borrower in the proportion provided in the Merger
Agreement.  Such amounts will be considered an Advance to each Borrower
hereunder, in the proportion provided in the Merger Agreement, as of the date
that such amounts are actually paid by Papnet.  Papnet shall keep adequate books
and records of such expenses which shall be available for inspection by any
Borrower during normal business hours upon reasonable prior notice.

    2.   ADVANCES OF OPERATING EXPENSES.   Through the Effective Date, Papnet
agrees to make such Advances to or on behalf of each Borrower individually as
are necessary to pay reasonable expenses of ordinary business operations of such
Borrower, as approved by Papnet. In the case of CWI, such expenses shall include
reasonable expenses necessary to the development of technologies acquired from
GDP Technologies, Inc. Each such Advance shall be made to or on

<PAGE>

behalf of a Borrower upon receipt of the Borrower's application therefor and
disbursement instructions, which shall be in a form as Papnet shall reasonably
prescribe, and will be considered an Advance to such Borrower hereunder.  The
reasonableness of any expenses for which Advances are requested, and the amount
of any Advance, shall be determined by Papnet in its sole discretion.

    3.   REPAYMENT.  The total amount of Advances to or on behalf of a Borrower
shall be repaid, with interest at the rate of seven percent (7.00%) per annum,
sixty days after the Termination Date, as defined in Section 5.  Each Borrower
may pay the unpaid principal amount of any Advance made to or on behalf of it in
whole or in part at any time and from time to time.  Each such payment of
principal may be made without the payment of accrued and unpaid interest
thereon.   Interest shall be calculated on the basis of a 360-day year for the
actual number of days the principal balance is unpaid.  After maturity, whether
such maturity occurs by lapse of time or acceleration, interest on the unpaid
balance of any Advances (and interest thereon accrued through maturity) shall
accrue at the rate of twenty four percent (24.00%) per annum until all Advances
and accrued interest are repaid in full. Advances to each Borrower shall be
evidenced by one or more promissory notes in the form of Exhibit A to this
Agreement, or by one or more notes subsequently executed in substitution
therefor.

    4    STATEMENTS.  On the 25th day of each month during the term of this
Agreement, Papnet shall deliver to each Borrower a statement showing, for the
immediately preceding month, all Advances made to or on behalf of such Borrower,
all payments or partial payments of the principal amount of Advances by the
Borrower, the accrued and unpaid interest on the Advances, if any, and such
other information as may be necessary or appropriate.   Each Borrower hereto
agrees that it will immediately notify Papnet of any error in any monthly
statement delivered to it, and the failure to do so within five (5) business
days shall be deemed to be a waiver of any claimed error.  Papnet's allocation
of Advances to any Borrower shall be presumed correct, and in the event of any
dispute concerning the amount, manner of calculation or allocation of any
Advance as shown on any statement, the party disputing the statement shall have
the burden of demonstrating any error.

    5.   TERMINATION.  Papnet's right and ability to make Advances hereunder
shall terminate upon a date (the "Termination Date") which is the earlier to
occur of (a) the closing of the Merger, or (b) the termination of the Merger
Agreement as provided in Article VIII thereof.

    6.   SECURITY.  As security for Advances to or on behalf of  it hereunder,
each Borrower other than CWI shall pledge to Papnet  all of the common shares of
Neuromedical Systems, Inc. currently owned by it, pursuant to the terms of a
Security Agreement in the form attached hereto as Exhibit B.  As security for
Advances to or on behalf of it, CWI shall grant Papnet a security interest in
its assets pursuant to the terms of a Security Agreement in the form attached
hereto as Exhibit C.

    7.   REPRESENTATIONS AND WARRANTIES OF BORROWERS.  In addition to the
representations and warranties of each Borrower contained in the Merger
Agreement, upon which each Borrower agrees that Papnet may rely for purposes of
this Agreement, each Borrower represents and warrants to Papnet that:


                                          2

    (a)  The Board of Directors of the Borrower has duly authorized the

compliance by the Borrower with all the provisions thereof:

         (i)  are within the corporate powers of the Borrower; and

              provisions of, constitute a default under, or result in the
              creation of any lien or encumbrance upon any property of the
              Borrower under the provisions of, any agreement, charter
              instrument, bylaw, or other instrument to which the Borrower is a
              party or by which it may be bound.

    8.   EVENTS OF DEFAULT.  An "Event of Default" with respect to a Borrower
shall exist if any of the following occurs and is continuing:

    (a)  the Borrower fails to pay any amount hereunder when due, or fails to
perform or observe any covenant contained in Article VI of the Merger Agreement;

    (b)  any warranty, representation or other statement by or on behalf of the
Borrower contained in this Agreement, the Merger Agreement, or in any instrument
furnished in compliance with or in reference to this Agreement is false or
misleading in any material respect;

    (c)  the Borrower becomes insolvent or bankrupt, or makes an assignment for
the benefit of creditors, or consents to the appointment of a trustee, receiver
or liquidator; or

    (d)  bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings are instituted by or against the Borrower.

    9.   DEFAULT REMEDIES.

    (a)  ACCELERATION.  If an Event of Default exists with respect to a
Borrower, Papnet may immediately exercise any right, power or remedy  permitted
to it by law, and shall have, in particular, without limiting the generality of
the foregoing, the right to declare the entire principal and all interest
accrued on all Advances then outstanding to or on behalf of such Borrower
pursuant to this Agreement to be forthwith due and payable, without any
presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived by each Borrower.


                                          3

<PAGE>

    (b)  NONWAIVER.  No course of dealing on the part of Papnet nor any delay
or failure on the part of Papnet to exercise any right shall operate as a waiver
of such right or otherwise prejudice Papnet's rights, powers and remedies.

    10.  MISCELLANEOUS.

    (a)  NOTICES.  All communications under this Agreement  shall be in writing
and shall be mailed by first class mail, postage prepaid.  Any notice so
addressed and mailed shall be deemed given when so mailed.

observance of any term of this Agreement may be waived, with (and only with) the
written consent of the parties hereto.

    (d)  DUPLICATE ORIGINALS.     Duplicate originals of this Agreement may be
signed by the parties, each of which shall be an original but all of which
together shall constitute one and the same instrument.

    (e)  GOVERNING LAW.  This Agreement shall be governed by and construed in
accordance with the laws of the State of Ohio applicable to contracts made and
performed entirely within such state, without regard to principles of conflicts
of laws.

    (f)  CONSENT TO JURISDICTION AND WAIVER OF OBJECTION TO VENUE.  Each party
agrees that any legal action or proceeding with respect to this Agreement or the
notes or the transactions contemplated hereby may be brought in the Court of
Common Pleas of Franklin County, Ohio, or in the United States District Court
for the Southern District of Ohio, Eastern Division, and each party hereby
irrevocably submits to and accepts generally and unconditionally the
jurisdiction of those courts with respect to its person, property and revenues
and irrevocably consents to service of process in any such action or proceeding
by the mailing thereof by U.S. mail to such party at the address set forth in
the Merger Agreement.  Each party hereby irrevocably waives any objection to the
laying of venue of any such suit or proceeding in the above described courts,
and unconditionally waives and agrees not to plead or claim that any such suit
or proceeding brought in any such court has been brought in an inconvenient
forum.

    (g)  WAIVER OF JURY TRIAL.  THE PARTIES ACKNOWLEDGE THAT, AS TO ANY AND ALL
DISPUTES THAT MAY ARISE BETWEEN THE PARTIES, THE COMMERCIAL NATURE OF THE
TRANSACTION OUT OF WHICH THIS AGREEMENT ARISES WOULD MAKE ANY SUCH DISPUTE
UNSUITABLE FOR TRIAL BY JURY.  ACCORDINGLY, EACH OF THE PARTIES TO THIS
AGREEMENT HEREBY WAIVES ANY RIGHT TO TRIAL BY JURY AS TO ANY AND ALL DISPUTES
THAT MAY ARISE

                                                           Columbus, Ohio
$585,000.00                                                April  5, 1996


    FOR VALUE RECEIVED, the undersigned promises to pay to the order of PAPNET
OF OHIO, INC. (hereinafter called the "Lender," which term shall include any
holder hereof) at such place as the Lender may designate or, in the absence of
such designation, at any of the Lender's offices, the sum of $585,000.00 or so
much of such sum as shall have been advanced by the Lender at any time and not
hereafter repaid (hereinafter referred to as "Advances") pursuant to the Loan
Agreement dated as of March 14, 1996 (the "Agreement") together with interest
provided and payable at the time(s) and in the manner(s) provided in the
Agreement.   Each such Advance shall be made to the undersigned upon receipt by
the Lender of the undersigned's application therefor and disbursement
instructions, which shall be in such form as the Lender shall from time to time
reasonably prescribe.  The Lender shall be entitled to rely on any oral or
telephonic communication requesting an Advance and/or providing disbursement
instructions hereunder, which shall be received by it in good faith from anyone
reasonably believed by the Lender to be the undersigned, or the undersigned's
authorized agent.  Each request for an Advance shall constitute a warranty and
representation by the undersigned that no event of default hereunder, under the
Agreement, or under any related loan documents has occurred and is continuing
and that no event or circumstance which would constitute such an event of
default, but for the requirement that notice be given or time elapse or both,
has occurred and is continuing.  The undersigned agrees that all Advances made
by the Lender will be evidenced by entries made by the Lender into records
maintained by the Lender.  The undersigned further agrees that the sum or sums
shown such records shall be rebuttably presumptive evidence of the amount of the
Advances and of the amount of any accrued interest.

INTEREST

    Interest will accrue on the unpaid balance of the Advances until paid at
the rate of 7% per annum.  Upon maturity, whether by acceleration or otherwise,
interest will accrue on the unpaid balance of the Advances and unpaid interest,
if any, until paid at the rate of 24% per annum.

    All interest shall be calculated on the basis of a 360 day year for the
actual number of days the Advances or any part thereof remain unpaid.  There
shall be no penalty for prepayment.

<PAGE>

pursuant to the Settlement Agreement among the Debtor, NSI and certain other
parties dated as of December 5, 1996 (hereinafter sometimes called the
"Intellectual Property")

(all of the foregoing hereinafter sometimes called the "Collateral").

    The security interest hereby granted is to secure the prompt and full
payment and complete performance of all Obligations.  The word "Obligations"
means all indebtedness owed by Debtor to Lender by reason of Advances made to or
on behalf of Debtor pursuant to a Loan Agreement of even date and related
documents.

    It is Debtor's express intention that this agreement and the continuing
security interest granted hereby, in addition to covering all present
Obligations of Debtor to Lender, shall extend to all future Obligations of
Debtor to Lender, whether or not such Obligations are reduced or entirely
extinguished and thereafter increased or reincurred, whether or not such
Obligations are related to the indebtedness identified above by class, type or
kind and whether or not such Obligations are specifically contemplated by Debtor
and Lender as of the date hereof.  The absence of any reference to this
agreement in any documents, instruments or agreements evidencing or relating to
any Obligation secured hereby shall not limit or be construed to limit the scope
or applicability of this agreement.

     1.  GENERAL COVENANTS.  Debtor represents, warrants and covenants as
follows:

         (a)  Except for the security interest granted hereby, (i) Debtor is,
or as to Collateral arising or to be acquired after the date hereof, shall be,
the sole and exclusive owner of the Collateral, and the Collateral is and shall
remain free from any and all liens, security interests, encumbrances, claims and
interests; and (ii) no security agreement, financing statement, equivalent
security or lien instrument or continuation statement covering any of the
Collateral is on file or of record in any public office.

         (b)  Debtor shall not create, permit or suffer to exist, and shall
take such action as is necessary to remove, any claim to or interest in or lien
or encumbrance upon the Collateral, other than the security interest granted
hereby, and shall defend the right, title and interest of Lender in and to the
Collateral against all claims and demands of all persons and entities at any
time claiming the same or any interest therein.

         (c)  Debtor's principal place of business/chief executive office is
located at the address set forth at the beginning of this agreement and Debtor
has no other place of business; and, unless Lender consents in writing to a
change in the location of the Equipment, Inventory or Debtor's records
concerning the Receivables prior to such a change in location, the Equipment,
Inventory and Debtor's records concerning the Receivables shall be kept at that
address .

         (d)  At least thirty (30) days prior to the occurrence of any of the
following events, Debtor shall deliver to Lender written notice of such
impending events:  (i) a change in Debtor's 


                                         -2-

<PAGE>

principal place of business or chief executive office; (ii) the opening or
closing of any place of business; or (iii) a change in Debtor's name, identity
or corporate structure.

         (e)  Subject to any limitation stated therein or in connection
therewith, all information furnished by Debtor concerning the Collateral or
otherwise in connection with the Obligations, is or shall be at the time the
same is furnished, accurate, correct and complete in all material respects.

         (f)  The Collateral is and shall be used primarily for business
purposes.

     2.  COLLECTION OF RECEIVABLES.  Debtor shall, unless otherwise directed by
Lender, collect all of Debtor's Receivables.  With respect to any Receivables
collected by the Lender, Debtor authorizes Lender to indorse the name of Debtor
upon any checks or other items received in payment of any Receivable and to do
any and all things necessary in order to reduce the same to money.  All amounts
received by Lender representing payment of Receivables may be applied by Lender
to the payment of the Obligations in such order of preference as Lender may
determine, or Lender may, at its option, impound all or any portion of such
amounts and retain said amounts as security for the payment of the Obligations,
with the right on the part of Debtor, upon approval by Lender, to obtain the
release of all or part of such impounded amounts. Lender may, however, at any
time, apply all or any part of such impounded amounts as aforesaid.  If so
directed by Lender, Debtor shall hold all payments of any Receivable in trust
for Lender and shall forthwith deliver the same to Lender in the form received
by Debtor without commingling with any funds of Debtor.  Debtor also authorizes
Lender at any time, without notice, to appropriate and apply any balances,
credits, property, deposits, accounts or money of or owing to Debtor in Lender's
possession, custody or control to the payment of any of the Obligations.

         If any of Debtor's Receivables arise out of contracts with or orders
from the United States or any State or any department, agency or instrumentality
thereof, Debtor shall immediately notify Lender thereof in writing and shall
execute  any instrument and take any steps required by Lender in order that all
money due and to become due under such contract or order shall be assigned to
Lender and due notice thereof given to the appropriate governmental agency.

         Debtor agrees to execute, deliver, file and record all such notices,
affidavits, assignments, financing statements and other instruments as shall in
the judgment of Lender be necessary or desirable to evidence, validate and
perfect the security interest of Lender in the Receivables.  Lender shall have
the right to notify any persons or entities owing any Receivables and to demand
and receive payment, but Lender shall have no duty so to do.  Upon request of
Lender at any time, Debtor shall notify such account debtors and shall indicate
on all invoices to such account debtors that the accounts are payable to Lender.

     3.  INSURANCE.  Debtor shall have and maintain insurance at all times with
respect to all Equipment and Inventory (i) insuring against risks of fire
(including so-called extended coverage), explosion, theft, sprinkler leakage and
such other casualties as Lender may designate, and (ii) 


                                         -3-

<PAGE>

insuring against liability for personal injury and property damage relating to
the Equipment and Inventory, containing such terms, in such form, for such
periods and written by such companies as may be satisfactory to Lender, such
insurance to be payable to Lender and Debtor as their interests may appear.  

     4.  INSPECTION.  Debtor shall at all times keep accurate and complete
records of the Receivables and Debtor shall, at all reasonable times and from
time to time, allow Lender, by or through any of its officers, agents, attorneys
or accountants, to examine, inspect and make extracts from Debtor's books and
records and to arrange for verification of the Receivables directly with account
debtors or by other methods and to examine and inspect the Collateral wherever
located.

     5.  FURTHER ASSURANCES.  Debtor shall perform, do, make, execute and
deliver all such additional and further acts, things, deeds, assurances and
instruments as Lender may require to more completely vest in and assure to
Lender its rights hereunder and in or to the Collateral.

     6.  PRESERVATION AND DISPOSITION OF COLLATERAL.

         (a)  Debtor shall advise Lender promptly, in writing and in reasonable
detail, (i) of any material encumbrance upon or claim asserted against any of
the Collateral; (ii) of any material change in the composition of the
Collateral; and (iii) of the occurrence of any other event that would have a
material effect upon the aggregate value of the Collateral or upon the security
interest of Lender.

         (b)  Debtor shall not sell or otherwise dispose of the Collateral;
provided, however, that until default, Debtor may use the Equipment and
Inventory in any lawful manner not inconsistent with this agreement or with the
terms or  conditions of any policy of insurance thereon and may also sell or
otherwise dispose of the Inventory in the ordinary course of Debtor's business. 
A disposition in the ordinary course of business shall not include a transfer in
partial or total satisfaction of a debt.

         (c)  Debtor shall keep the Collateral in good condition and shall not
misuse, abuse, secrete, waste or destroy any of the same.

         (d)  Debtor shall not use the Collateral in violation of any statute,
ordinance, regulation, rule, decree or order.

         (e)  Debtor shall pay promptly when due all taxes, assessments,
charges or levies upon the Collateral or in respect to the income or profits
therefrom, except that no such charge need be paid if (i) the validity thereof
is being contested in good faith by appropriate proceedings; (ii) such
proceedings do not involve any danger of sale, forfeiture or loss of any
Collateral or any interest therein; and (iii) such charge is adequately reserved
against in accordance with generally accepted accounting principles.


                                         -4-

<PAGE>

         (f)  At its option, Lender may discharge taxes, liens, security
interests or other encumbrances at any time levied or placed on the Collateral
and may pay for the maintenance and preservation of the Collateral.  Debtor
agrees to reimburse Lender upon demand for any payment made or any expense
incurred (including reasonable attorneys' fees to the extent permitted by law)
by Lender pursuant to the foregoing authorization.  Should Debtor fail to pay
said sum to Lender upon demand, interest shall accrue thereon, from the date of
demand until paid in full, at the highest rate set forth in any document or
instrument evidencing any of the Obligations.

         (g)  Upon Lender's request at any time or times, Debtor shall assign
and deliver to Lender any Collateral and shall furnish to Lender additional
collateral of value and character satisfactory to Lender as security for the
Obligations.

     7.  EXTENSIONS AND COMPROMISES.  With respect to any Collateral held by
Lender as security for the Obligations, Debtor assents to all extensions or
postponements of the time of payment thereof or any other indulgence in
connection therewith, to each substitution, exchange or release of Collateral,
to the addition or release of any party primarily or secondarily liable, to the
acceptance of partial payments thereon and to the settlement, compromise or
adjustment thereof, all in such manner and at such time or times as Lender may
deem advisable.  Lender shall have no duty as to the collection or protection of
Collateral or any income therefrom, nor as to the preservation of rights against
prior parties, nor as to the preservation of any right pertaining thereto,
beyond the safe custody of Collateral in the possession of Lender.

     8.  FINANCING STATEMENTS.  At the request of Lender, Debtor shall join
with Lender in executing one or more financing statements in a form satisfactory
to Lender and shall pay the cost of filing the same in all public offices
wherever filing is deemed by Lender to be necessary or desirable.  A carbon,
photographic or other reproduction of this agreement or of a financing statement
shall be sufficient as a financing statement.

     9.  LENDER'S APPOINTMENT AS ATTORNEY-IN-FACT.  Debtor hereby irrevocably
constitutes and appoints Lender and any officer or agent thereof, with full
power of substitution, as Debtor's true and lawful attorney-in-fact with full
irrevocable power and authority in the place and stead of Debtor and in the 
name of Debtor or in Lender's own name, from time to time in Lender's
discretion, for the purpose of carrying out the terms of this agreement, to take
any and all appropriate action and to execute any and all documents and
instruments that may be necessary or desirable to accomplish the purposes of
this agreement and, without limiting the generality of the foregoing, hereby
grants to Lender the power and right, on behalf of Debtor, without notice to or
assent by Debtor:

         (a)  To execute, file and record all such financing statements,
certificates of title and other certificates of registration and operation and
similar documents and instruments including, but not limited to, those relating
to aircraft or marine vessels, as Lender may deem necessary or desirable to
protect, perfect and validate Lender's security interest.


                                         -5-

<PAGE>

         (b)  Upon the occurrence and continuance of any event of default under
paragraph 10 hereof, (i) to sign and indorse any invoices, freight or express
bills, bills of lading, storage or warehouse receipts, drafts against debtors,
assignments, verifications and notices in connection with accounts and other
documents relating to the Collateral; (ii) to commence and prosecute any suits,
actions or proceedings at law or in equity in any court of competent
jurisdiction to collect the Collateral or any part thereof and to enforce any
other right in respect of any Collateral; (iii) to defend any suit, action or
proceeding brought against Debtor with respect to any Collateral; (iv) to
settle, compromise or adjust any suit, action or proceeding described above and,
in connection therewith, to give such discharges or releases as Lender may deem
appropriate; and (v) generally, to sell, transfer, pledge, make any agreement
with respect to or otherwise deal with any of the Collateral as fully and
completely as though Lender were the absolute owner thereof for all purposes,
and to do, at Lender's option and Debtor's expense, at any time or from time to
time, all acts and things which Lender deems necessary to protect, preserve or
realize upon the Collateral and Lender's security interest therein, in order to
effect the intent of this agreement, all as fully and effectively as Debtor
might do.

         Debtor hereby ratifies all that said attorneys shall lawfully do or
cause to be done by virtue hereof.  This power of attorney is a power coupled
with an interest and shall be irrevocable.

         The powers conferred upon Lender hereunder are solely to protect its
interests in the Collateral and shall not impose any duty upon Lender to
exercise any such powers.  Lender shall be accountable only for amounts that
Lender actually receives as a result of the exercise of such powers and neither
Lender nor any of its officers, directors, employees or agents shall be
responsible to Debtor for any act or failure to act, except for Lender's own
gross negligence or willful misconduct.

    10.  DEFAULT.  If any event of default in the payment of any of the
Obligations or in the performance of any of the terms, conditions, or provisions
of any instrument or document evidencing the Obligations secured by this
agreement or in the performance of any covenant contained herein shall occur and
be continuing; or if any warranty, representation or statement made or furnished
to Lender by Debtor proves to have been false in any material respect when made
or furnished:

         (a)  Lender may, at its option and without notice, declare the unpaid
balance of any or all of the Obligations immediately due and payable and this
agreement and any or all of the Obligations in default.

         (b)  All payments received by Debtor under or in connection with any
of the Collateral shall be held by Debtor in trust for Lender, shall be
segregated from other funds of Debtor and shall forthwith upon receipt by Debtor
be turned over to Lender in the same form as received by Debtor (duly indorsed
by Debtor to Lender, if required).  Any and all such payments so received by
Lender (whether from Debtor or otherwise) may, in the sole discretion of Lender,
be held by Lender as collateral security for, and/or then or at any time
thereafter be applied in whole or in part by Lender against, all or any part of
the Obligations in such order as Lender may elect.  Any balance of such payments
held by Lender and remaining after payment in full of all the Obligations shall
be 


                                         -6-

<PAGE>

paid over to Debtor or to whomsoever may be lawfully entitled to receive the
same.  Nothing set forth in this subparagraph (b) shall authorize or be
construed to authorize Debtor to sell or otherwise dispose of any Collateral
except as provided in subparagraph 6(b) hereof.

         (c)  Lender shall have the rights and remedies of a secured party
under this agreement, under any other instrument or agreement securing,
evidencing or relating to the Obligations and under the laws of the States of
Ohio and Nevada.  Without limiting the generality of the foregoing, Lender shall
have the right to take possession of the Collateral and all books and records
relating to the Collateral and for that purpose Lender may enter upon any
premises on which the Collateral or books and records relating to the Collateral
or any part thereof may be situated and remove the same therefrom.  Debtor
expressly agrees that Lender, without demand of performance or other demand,
advertisement or notice of any kind (except the notices specified below of time
and place of public sale or disposition or time after which a private sale or
disposition is to occur) to or upon Debtor or any other person or entity (all
and each of which demands, advertisements and/or notices are hereby expressly
waived), may forthwith collect, receive, appropriate and realize upon the
Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give
option or options to purchase or sell or otherwise dispose of and deliver the
Collateral (or contract to do so), or any part thereof, in one or more parcels
at public or private sale or sales, at any of Lender's offices or elsewhere at
such prices as Lender may deem best, for cash or on credit or for future
delivery without assumption of any credit risk.  Lender shall have the right
upon any such public sale or sales, and, to the extent permitted by law, upon
any such private sale or sales, to purchase the whole or any part of the
Collateral so sold, free of any right or equity of redemption in Debtor.  Debtor
further agrees, at Lender's request, to assemble the Collateral and to make it
available to Lender at such places as Lender may reasonably select, whether at
Debtor's premises or elsewhere.  Debtor further agrees to allow Lender to use or
occupy Debtor's premises, without charge, for the purpose of effecting Lender's
remdies in respect of the Collateral.  Lender shall apply the net proceeds of
any such collection, recovery, receipt, appropriation, realization or sale,
after deducting all reasonable costs and expenses of every kind incurred in
connection therewith or incidental to the care or safekeeping of any or all of
the Collateral or in any way relating to the rights of Lender hereunder,
including reasonable attorneys' fees to the extent permitted by law and
reasonable legal expenses, to the payment in whole or in part of the
Obligations, in such order as Lender may elect, and only after so paying over
such net proceeds and after the payment by Lender of any other amount required
by any provision of law, need Lender account for the surplus, if any, to 
Debtor.  To the extent permitted by applicable law, Debtor waives all claims, 
damages and demands against Lender arising out of the repossession, retention, 
sale or disposition of the Collateral.  Debtor agrees that Lender need not 
give more than  seven (7) days' notice (which notification shall be deemed 
given when mailed, postage prepaid, addressed to Debtor at Debtor's address 
set forth at the beginning of this agreement or when telecopied or telegraphed 
to that address or when telephoned or otherwise communicated orally to Debtor 
or any agent of Debtor at that address) of the time and place of any public 
sale or of the time after which a private sale may take place and that such 
notice is reasonable notification of such matters.  Debtor shall remain 
liable for any deficiency if the proceeds of any sale or disposition of the 
Collateral are insufficient to pay all amounts to which Lender is entitled.  
Debtor shall also be liable for the costs of collecting any of the Obligations 
or otherwise enforcing 


                                         -7-

<PAGE>

the terms thereof or of this agreement including reasonable attorneys' fees to
the extent permitted by law.

         (d)  In the event of a default, in lieu of exercising its remedies
with respect to the Collateral provided in this Section 10, Lender may apply the
amount of the outstanding Obligations secured hereby to the purchase of common
shares of Debtor at a price of $8.50 per share (the "Conversion Price"), and 
Debtor agrees to sell such number of shares to Lender.  Debtor agrees to
maintain sufficient authorized and unissued shares sufficient to discharge its
obligations under this paragraph, and that upon issuance to Lender as provided
herein, such shares shall be duly authorized, validly issued, fully paid and
nonassessable, and free of any lien, claim, preemptive right or other
restriction, except for restrictions on transfer necessary to comply with
applicable securities laws.  If subsequent to the date of this Agreement the
Debtor issues common stock representing more than 1% of the outstanding common
equity of Debtor on a fully diluted basis for a consideration per share with a
value of less than $8.50, other than upon the exercise of stock options or
warrants outstanding on the date hereof, then the Conversion Price shall be
reduced to a price equal to such value.   In case the Debtor shall (i) pay a
dividend on its common stock in common stock, (ii) subdivide its outstanding
shares of common stock, or (iii) combine its outstanding shares of common stock
into a small number of shares, then, in such an event, the Conversion Price in
effect immediately prior thereto shall be adjusted proportionately so that the
adjusted Conversion Price will bear the same relation to the Conversion Price in
effect immediately prior to any such event as the total number of shares of
common stock outstanding immediately prior to any such event shall bear to the
total number of shares of common stock outstanding immediately after such event.


    11.  GENERAL.  Any provision of this agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.  Lender shall not be deemed to have waived any of its rights
hereunder or under any other agreement, instrument or paper signed by Debtor
unless such waiver be in writing and signed by Lender.  No delay or omission on
the part of Lender in exercising any right shall operate as a waiver of such
right or any other right.  All of Lender's rights and remedies, whether
evidenced hereby or by any other agreement, instrument or paper, shall be
cumulative and may be exercised singularly or concurrently.  Any written demand
upon or written notice to Debtor shall be effective when deposited in the mails
addressed to Debtor at the address shown at the beginning of this agreement. 
This agreement and all rights and obligations hereunder, including matters of
construction, validity and performance, shall be governed by the law of the
State of Ohio.  The provisions hereof shall, as the case may require, bind or
inure to the benefit of, the respective successors and assigns of Debtor and
Lender.

                                       GUARANTY


    For the purpose of inducing Papnet of Ohio, Inc. (hereinafter referred to
as "Lender") to lend money or advance credit to, or renew, extend or forbear
from demanding immediate payment of the Obligations (as such term is defined
below) of Cytology West, Inc. (hereinafter referred to as "Debtor") the
undersigned (hereinafter referred to as "Guarantor"), hereby unconditionally
guarantees the prompt and full payment to Lender when due, whether by
acceleration or otherwise, of all Obligations for which Debtor is now or may
hereafter become liable to Lender.

    The word "Obligations" means all indebtedness, debts and liabilities
(including principal, interest, late charges, collection costs, attorneys' fees
and the like) of  Debtor to Lender pursuant to that certain Loan Agreement and
related loan documents dated March 14, 1996.

    Guarantor hereby promises that if the Obligations are not paid promptly
when due, upon request of Lender he will pay the Obligations to Lender,
irrespective of any action or lack of action on Lender's part in connection with
the acquisition, perfection, possession, enforcement or disposition of any or
all Obligations or any or all security therefor or otherwise, and further
irrespective of any invalidity in any or all Obligations, the unenforceability
thereof or the insufficiency, invalidity or unenforceability of any security
therefor.

    Guarantor waives notice of any and all acceptances of this Guaranty.
Lender's rights hereunder shall be reinstated and revived, and this Guaranty
shall be fully enforceable, with respect to any amount at any time paid on
account of the Obligations which thereafter shall be required to be restored or
returned by Lender as a result of the bankruptcy, insolvency or reorganization
of Debtor, Guarantor, or any other person, or as a result of any other fact or
circumstance, all as though such amount had not been paid.

    Guarantor waives presentment, demand, protest, notice of protest and notice
of dishonor or other nonpayment of any and all Obligations and further waives
notice of sale or other disposition of any collateral or security now held or
hereafter acquired by Lender.  Guarantor agrees that no extension of time,
whether one or more, nor any other indulgence granted by Lender to Debtor, or to
Guarantor, and no omission or delay on Lender's part in exercising any right
against, or in taking any action to collect from or pursue Lender's remedies
against Debtor or Guarantor, will release, discharge or modify the duties of
Guarantor.  Guarantor agrees that Lender may, without notice to or further
consent from Guarantor, release or modify any collateral, security or other
guaranties now held or hereafter acquired, or substitute other collateral,
security or other guaranties, and no such action will release, discharge or
modify the duties of Guarantor hereunder.  Guarantor further agrees that Lender
will not be required to pursue or exhaust any of its rights or remedies against
Debtor or Guarantor, with respect to payment of any of the Obligations, or to
pursue, exhaust or preserve any of its rights or remedies with respect to any
collateral, security or other guaranties given to secure the Obligations, or to
take any action of any sort, prior to demanding payment from or pursuing its
remedies against Guarantor.

<PAGE>

    Guarantor shall not be liable to Lender hereunder for more than $300,000 
in principal amount of the Obligations, plus interest, late charges,
collection costs, attorneys' fees and the like as provided for in the
Obligations.  Nothwithstanding the foregoing limitation, Lender may permit the
Obligations of Debtor to exceed the liability of Guarantor to Lender hereunder.

    Guarantor agrees that any legal suit, action or proceeding arising out of
or relating to this Guaranty may be instituted in a state or federal court of
appropriate subject matter jurisdiction in the State of Ohio; waive any
objection which he may have now or hereafter to the venue of any such suit,
action or proceeding; and irrevocably submits to the jurisdiction of any such
court in any such suit, action or proceeding.

WAIVER OF RIGHT TO TRIAL BY JURY

GUARANTOR ACKNOWLEDGES THAT, AS TO ANY AND ALL DISPUTES THAT MAY ARISE BETWEEN
GUARANTOR AND LENDER, THE COMMERCIAL NATURE OF THE TRANSACTION OUT OF WHICH THIS
GUARANTY ARISES WOULD MAKE ANY SUCH DISPUTE UNSUITABLE FOR TRIAL BY JURY.
ACCORDINGLY, GUARANTOR HEREBY WAIVES ANY RIGHT TO TRIAL BY JURY AS TO ANY AND
ALL DISPUTES THAT MAY ARISE RELATING TO THIS GUARANTY OR TO ANY OF THE OTHER
INSTRUMENTS OR DOCUMENTS EXECUTED IN CONNECTION HEREWITH.

    Guarantor hereby authorizes any attorney at law to appear for him in any
action on any or all Obligations guaranteed hereby at any time after such
Obligations become due, whether by acceleration or otherwise, in any court of
record in or of the State of Ohio or elsewhere, to waive the issuing and service
of process against, and confess judgment against Guarantor in favor of Lender
for the amount that may be due, including interest, late charges, collection
costs, attorneys' fees and the like as provided for in said Obligations, and
costs of suit, and to waive and release all errors in said proceedings and
judgments, and all petitions in error and rights of appeal from the judgments
rendered.  The attorney at law authorized hereby to appear for the Guarantor may
be an attorney at law representing the Lender, and Guarantor hereby expressly
waives any conflict of interest that may exist by virtue of such representation.

    If any Obligation of Debtor is assigned by Lender, this Guaranty will inure
to the benefit of Lender's assignee, and to the benefit of any subsequent
assignee, to the extent of the assignment or assignments, provided that no
assignment will operate to relieve Guarantor from any duty to Lender hereunder
with respect to any unassigned Obligation.  In the event that any one or more of
the provisions contained in this Guaranty or any application thereof shall be
determined to be invalid, illegal or unenforceable in any respect, the validity,
legality and enforceability of the remaining provisions contained herein and any
other applications thereof shall not in any way be affected or impaired thereby.
This Guaranty shall be construed in accordance with the laws of the State of
Ohio.

    As security for payment by Guarantor hereunder, Guarantor has, by a
Security Agreement of even date,  granted Lender a security interest in certain
property of  (hereinafter the


                                          2

"Collateral").Lender shall not be bound to take any steps necessary to preserve
any rights in the Collateral against prior parties.  If any Obligations
hereunder are not paid when due, Lender may, at its option, demand, sue for,
collect or make any compromise or settlement it deems desirable with reference
to the Collateral, and shall have the rights of a secured party under the law of
the State of Ohio.  Guarantor shall be liable for any deficiency.

    Executed and delivered at Las Vegas, Nevada this 4th day of April, 1996.


                               GUARANTOR:

                                  CERTIFICATED STOCK

    The undersigned (hereinafter called "Debtor"), for valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, hereby grants,
pledges and assigns to Papnet of Ohio, Inc. (hereinafter called "Lender"), a
security interest in the following stock, whether Debtor's interest therein be
now owned or existing or hereafter arising or acquired, together with all
substitutions, replacements, exchanges, reissues and additions therefor or
thereto, all books and records relating thereto, all dividends and distributions
arising therefrom, payable thereon or distributed in respect thereto, whether in
cash, property, stock or otherwise, and whether now or hereafter declared, paid
or made, and together with the right to receive and receipt therefor, and all
cash and non-cash proceeds thereof including, but not limited to, notes, drafts,
checks, instruments and deposit and money market accounts:

No. of Shares                                                   Certificate
and Class                              Issuer              Number(s)
- ---------------                         ------              ---------

17,150 Common Shares,
$.0001 par value             Neuromedical Systems, Inc.         121


(all of the foregoing hereinafter sometimes called the "Collateral").  Except as
otherwise provided in this agreement, Debtor shall have the right to receive all
dividends arising with respect to the Collateral paid in cash or in other
property, but Debtor shall have no right to receive any dividend in respect of
the Collateral paid in stock of the Issuer or in the stock of corporations other
than the Issuer or paid out of the proceeds of the sale or condemnation of any
property of the Issuer or upon or in the course of dissolution or liquidation
(whether partial or otherwise) or winding up of the Issuer or which in any way
shall be chargeable to or payable out of capital, capital surplus or paid in
surplus.  Debtor shall not have the right to receive any dividends arising with
respect to the Collateral if a default exists in the observance and performance
by Debtor of any of the terms of this agreement, or of any of the Obligations,
or if ownership of the Collateral has been registered in the name of Lender or
any nominee of Lender or any sub-agent appointed by Lender pursuant to paragraph
7 of this agreement, and all dividends arising under such circumstances shall be
paid to Lender and, at Lender's option, may be applied to the Obligations in
such order as Lender may elect or be held as security therefor.

    The security interest hereby granted is to secure the prompt and full
payment and complete performance of all Obligations of Debtor to Lender.  The
word "Obligations" means all indebtedness owed by Debtor to Lender by reason of
a certain Guaranty executed and delivered by Debtor to Lender of even date,
which guarantees payment of certain Advances made by Lender to or on behalf of
Cytology West, Inc., a Delaware corporation, pursuant to a Loan Agreement and
related documents dated March 14, 1996.

<PAGE>

          1.  GENERAL COVENANTS.  Debtor represents, warrants and covenants as
follows:

         (a)  Unless Lender compels registration of ownership of the Collateral
in the name of Lender or any nominee of Lender or any sub-agent appointed by
Lender pursuant to paragraph 7 of this agreement, Debtor is and shall remain the
sole owner and registered holder of the Collateral.

         (b)  Except for the security interest granted hereby, the Collateral
is and shall remain free from any and all security interests, liens,
encumbrances, claims and interests.

         (c)  Each share of stock comprising the Collateral is fully paid and
nonassessable and, except as otherwise indicated in the certificates
representing the shares, is transferable in its present form upon delivery
without restriction or limitation on the books and records of its Issuer.

         (d)  Debtor shall, at Debtor's expense, perform, do, make, procure,
execute and deliver all acts, things, writings and other assurances as Lender
may at any time request or require to protect, assure or enforce Lender's
interests, rights and remedies created by, provided in or emanating from this
agreement.

         (e)  Debtor shall not create, permit or suffer to exist, and shall
take such action as is necessary to remove, any claim to or interest in or lien
or encumbrance upon the Collateral, other than the security interest granted
hereby, and shall defend the right, title and interest of Lender in and to the
Collateral against all claims and demands of all persons and entities at any
time claiming the same or any interest therein.

         (f)  Subject to any limitation stated therein or in connection
therewith, all information furnished by Debtor concerning the Collateral or
otherwise in connection with the Obligations, is or shall be at the time the
same is furnished accurate, correct and complete in all material respects.

     2.  VOTING.  With respect to any Collateral not registered in the name of
Lender or Lender's nominee or sub-agent pursuant to paragraph 7 of this
agreement, during the term of this agreement, and so long as (i) there is no
default by Debtor in the observance and performance of any of the terms of this
agreement or of any of the Obligations, and (ii) Lender has not notified Debtor
of Lender's election to exercise any voting rights relating to the Collateral,
Debtor shall have the right to exercise such voting rights on all corporate
questions.

     3.  SUBSTITUTED AND ADDITIONAL SECURITIES.  If during the term of this
agreement any stock dividend, exchange, conversion, reclassification,
readjustment or other change is paid, declared or made with respect to the
Collateral, all new, substituted and additional securities issued in respect to
the Collateral shall be deemed pledged to Lender under the terms of this
agreement in the same manner as the Collateral originally pledged hereunder.


                                         -2-

<PAGE>

     4.  WARRANTS AND OPTIONS.  If during the term of this agreement
subscription warrants or options are issued in connection with the Collateral or
any other securities at the time pledged to Lender hereunder, such warrants and
options shall be immediately delivered and pledged by Debtor to Lender, and all
new securities acquired by Debtor in connection therewith shall be immediately
delivered and pledged to Lender under the terms of this agreement in the same
manner as the Collateral originally pledged hereunder.

     5.  PRESERVATION AND DISPOSITION OF COLLATERAL.

         (a)  Debtor shall advise Lender promptly, in writing and in reasonable
detail, (i) of any material encumbrance upon or claim asserted against any of
the Collateral; and (ii) of the occurrence of any event that would have a
material effect upon the aggregate value of the Collateral or upon the security
interest of Lender.

         (b)  Debtor shall pay promptly when due all taxes, assessments,
charges or levies upon the Collateral or in respect to the income or profits
therefrom or the transfer or registration thereof.

         (c)  At its option, Lender may discharge taxes, liens, security
interests or other encumbrances at any time levied or placed on or arising in
connection with the Collateral.  Debtor agrees to reimburse Lender upon demand
for any payment made or any expense incurred (including reasonable attorneys'
fees to the extent permitted by law) by Lender pursuant to the foregoing
authorization.  Should Debtor fail to pay said sum to Lender upon demand,
interest shall accrue thereon, from the date of demand until paid in full, at
the highest rate set forth in any document or instrument evidencing any of the
Obligations.

     6.  EXTENSIONS AND COMPROMISES.  With respect to any Collateral pledged to
Lender as security for the Obligations, Debtor assents to all extensions or
postponements of the time of payment thereof or any other indulgence in
connection therewith, to each substitution, exchange or release of Collateral,
to the addition or release of any party primarily or secondarily liable, to the
acceptance of partial payments thereon and to the settlement, compromise or
adjustment thereof, all in such manner and at such time or times as Lender may
deem advisable.  Lender shall have no duty as to the collection or protection of
Collateral or any income therefrom, nor as to the preservation of any right
pertaining thereto, beyond the safe custody of Collateral in the possession of
Lender.

     7.  LENDER'S APPOINTMENT AS ATTORNEY-IN-FACT.  Debtor hereby irrevocably
constitutes and appoints Lender and any officer or agent thereof, with full
power of substitution, as Debtor's true and lawful attorney-in-fact with full
irrevocable power and authority in the place and stead of Debtor and in the name
of Debtor or in Lender's own name, from time to time in Lender's discretion, for
the purpose of carrying out the terms of this agreement, to take any and all
appropriate action and to execute any and all documents and instruments that may
be necessary or desirable to accomplish the purpose of this agreement.


                                         -3-

<PAGE>

         Debtor hereby ratifies all that said attorneys shall lawfully do or
cause to be done by virtue hereof.  This power of attorney is a power coupled
with an interest and shall be irrevocable.

         In the event of any default by Debtor in the observance and
performance of any of the terms of this agreement or any of the Obligations,
Lender may at any time thereafter, in its discretion, register ownership of any
of the Collateral in the name of Lender or any nominee of Lender or any
sub-agent appointed by Lender, or may designate a nominee or sub-agent for the
purpose of retaining physical possession of the instruments, certificates and
similar writings representing any of the Collateral, indorsed or assigned in
blank or in favor of Lender or Lender's nominee or sub-agent.

         Debtor hereby consents and agrees that the Issuer or any obligor in
respect of the Collateral or any registrar or transfer agent or trustee for any
of the Collateral shall be entitled to accept the provisions hereof as
conclusive evidence of the rights of Lender to effect any transfer pursuant to
this paragraph 7, notwithstanding any other notice or direction to the contrary
heretofore or hereafter given.

         The powers conferred upon Lender hereunder are solely to protect its
interests in the Collateral and shall not impose any duty upon Lender to
exercise any such powers.  Lender shall be accountable only for amounts that
Lender actually receives as a result of the exercise of such powers and neither
Lender nor any of its officers, directors, employees or agents shall be
responsible to Debtor for any act or failure to act, except for Lender's own
gross negligence or willful misconduct.

     8.  DEFAULT.  If any event of default in the payment  of any of the
Obligations or in the performance of any of the terms, conditions, or provisions
of any instrument or document evidencing the Obligations secured by this
agreement or in the performance of any covenant contained herein shall occur and
be continuing; or if any warranty, representation or statement made or furnished
to Lender by Debtor proves to have been false in any material respect when made
or furnished:

         (a)  Lender may, at its option and without notice, declare the unpaid
balance of any or all of the Obligations immediately due and payable and this
agreement and any or all of the Obligations in default.

         (b)  All payments received by Debtor under or in connection with any
of the Collateral shall be held by Debtor in trust for Lender, shall be
segregated from other funds of Debtor and shall forthwith upon receipt by Debtor
be turned over to Lender in the same form as received by Debtor (duly indorsed
by Debtor to Lender, if required).  Any and all such payments so received by
Lender (whether from Debtor or otherwise) may, in the sole discretion of Lender,
be held by Lender as collateral security for, and/or then or at any time
thereafter be applied in whole or in part by Lender against, all or any part of
the Obligations in such order as Lender may elect.  Any balance of such payments
held by Lender and remaining after payment in full of all of the Obligations
shall be paid over to Debtor or to whomsoever may be lawfully entitled to
receive the same.  Nothing set forth in this subparagraph (b) shall authorize or
be construed to authorize Debtor to sell or otherwise dispose of any Collateral.


                                         -4-

<PAGE>

         (c)  Lender and its nominees and sub-agents shall have the rights and
remedies of a secured party under this agreement, under any other instrument or
agreement securing, evidencing or relating to the Obligations and under the laws
of the State of Ohio.  To the extent permitted by applicable law, Debtor waives
all claims, damages and demands against Lender arising out of the repossession,
retention, sale or disposition of the Collateral.  Debtor agrees that Lender
need not give more than ten (10) days' notice (which notification shall be
deemed given when mailed, postage prepaid, addressed to Debtor at Debtor's
address set forth at the beginning of this agreement, or when telecopied or
telegraphed to that address or when telephoned or otherwise communicated orally
to Debtor or any agent of Debtor at that address), if any, of the time and place
of any public sale or of the time after which a private sale may take place and
that such notice is reasonable notification of such matters.  Debtor shall
remain liable for any deficiency if the proceeds of any sale or disposition of
the Collateral are insufficient to pay all amounts to which Lender is entitled.
Debtor shall also be liable for the costs of collecting any of the Obligations
or otherwise enforcing the terms thereof or of this agreement including
reasonable attorneys' fees to the extent permitted by law.

     9.  GENERAL.  Any provision of this agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.  Lender shall not be deemed to have waived any of its rights
hereunder or under any other agreement, instrument or paper signed by Debtor
unless such waiver be in writing and signed by Lender.  No delay or omission on
the part of Lender in exercising any right shall operate as a waiver of such
right or any other right.  All of Lender's rights and remedies, whether
evidenced hereby or by any other agreement, instrument or paper, shall be
cumulative and may be exercised singularly or concurrently.  Any written demand
upon or written notice to Debtor shall be effective when deposited in the mails
addressed to Debtor at the address shown at the beginning of this agreement.
This agreement and all rights and obligations hereunder, including matters of
construction, validity and performance, shall be governed by the laws of the
State of Ohio.  The provisions hereof shall, as the case may require, bind or
inure to the benefit of the respective successors and assigns of Debtor and
Lender.

         IN WITNESS WHEREOF, Debtor has signed this agreement this 4th day of
April, 1996.

                                 PAPNET OF OHIO, INC.

                                 AMENDED AND RESTATED

                                1995 STOCK OPTION PLAN


     1.  PURPOSE.  This plan (the "Plan") is intended as an incentive and to
encourage stock ownership by certain key associates, officers, directors,
consultants and advisers who render services to PAPNET OF OHIO, INC., an Ohio
corporation (the "Company"), and any current or future subsidiaries or parent of
the Company (the "Company Group"), by the granting of stock options (the
"Options") as provided herein.  By encouraging such stock ownership, the Company
seeks to attract, retain and motivate employees, officers, directors,
consultants and advisers of training, experience and ability.  The Options
granted under the Plan may be either incentive stock options ("ISOs") which meet
the requirements of Section 422 of the Internal Revenue Code of 1986, as amended
(the "Code"), or options which do not meet such requirements ("Non-statutory
Options").  

     2.  EFFECTIVE DATE.  The Plan shall become effective on September 28,
1995, the date the Plan was approved by a majority of the shares of common stock
of the Company entitled to vote thereon (the "Effective Date"). 

     3.  ADMINISTRATION.

         (a)  The Plan shall be administered by the Board of Directors of the
Company (the "Board"), which may, to the full extent permitted by law, delegate
all or any of its powers under the Plan to a committee (the "Committee") which
consists of not fewer than two members of the Board.  If the Committee is so
appointed and to the extent such powers are delegated, all references to the
Board in the Plan shall mean and relate to the Committee.  If any class of
equity securities of the Company is registered under section 12 of the
Securities Exchange Act of 1934, as amended (the "1934 Act"), all members of the
Committee will be "disinterested persons" as defined in Rule 16b-3(c)(2)(i)
promulgated under the 1934 Act (or any successor rule of like tenor and effect)
and "outside directors" as defined in section 162(m) of the Code and the
regulations promulgated thereunder.

         (b)  Subject to the provisions of the Plan, the Board is authorized to
establish, amend and rescind such rules and regulations as it may deem
appropriate for its conduct and for the proper administration of the Plan, to
make all determinations under and interpretations of, and to take such actions
in connection with, the Plan or the Options granted thereunder as it may deem
necessary or advisable.  All actions taken by the Board under the Plan shall be
final and binding on all persons.  No member of the Board shall be liable for
any action taken or determination made relating to the Plan, except for gross
negligence or willful misconduct.

<PAGE>

         (c)  Each member of the Board shall be indemnified by the Company
against costs, expenses and liabilities (other than amounts paid in settlements
to which the Company does not consent, which consent shall not be unreasonably
withheld) reasonably incurred by such member in connection with any action taken
in relation to the Plan to which he or she may be a party by reason of service
as a member of the Board, except in relation to matters as to which he or she
shall be adjudged in such action to be personally guilty of gross negligence or
willful misconduct in the performance of his or her duties.  The foregoing right
to indemnification shall be in addition to such other rights as the Board member
may enjoy as a matter of law, by reason of insurance coverage of any kind, or
otherwise.

     4.  ELIGIBILITY.  

         (a)  ISOs and Non-statutory Options may be granted to such key
associates of the Company Group, and Non-statutory Options only may be granted
to directors who are not employees of and to consultants and advisers who render
services to the Company Group, as the Board shall select from time to time (the
"Optionees").  More than one Option may be granted to an individual under the
Plan.

         (b)  No ISO may be granted to an individual who, at the time an ISO is
granted, is considered under Section 422(b)(6) of the Code to own stock
possessing more than 10 percent of the total combined voting power of all
classes of stock of the Company or of its parent or any subsidiary corporation;
PROVIDED, HOWEVER, this restriction shall not apply if at the time such ISO is
granted the option price per Share of such ISO shall be at least 110% of the
fair market value of such Share, and such ISO by its terms is not exercisable
after the expiration of five years from the date it is granted.  This
subparagraph 4(b) has no application to Options granted under the Plan as
Non-statutory Options.

         (c)  The aggregate fair market value (determined as of the date the
ISO is granted) of Shares with respect to which ISOs are exercisable for the
first time by any Optionee during any calendar year under the Plan or any other
ISO plan of the Company or the Company Group may not exceed $100,000.  If an ISO
which exceeds the $100,000 limitation of this subparagraph 4(c) is granted, the
portion of such Option which is exercisable for Shares in excess of the $100,000
limitation shall be treated as a Non-statutory Option pursuant to Section 422(d)
of the Code.  Except as otherwise expressly provided in the immediately
preceding sentence, this subparagraph 4(c) has no application to Options granted
under the Plan as Non-statutory Options.
 
     5.  STOCK SUBJECT TO PLAN.  The stock subject to Options under the Plan
shall be shares of the common stock, no par value, of the Company ("Shares"). 
The Shares issued pursuant to Options granted under the Plan may be authorized
and unissued Shares, Shares purchased on the open market or in a private
transaction, or Shares held as treasury stock.  The aggregate number of Shares
for which Options may be granted under the Plan shall not exceed 150,000 shares,
subject to adjustment in accordance with the terms of paragraph 12 hereof.  Any
Shares subject to an Option which for any reason expires or is terminated
unexercised as to such Shares and any Shares reacquired by the Company pursuant
to any forfeiture or any repurchase right hereunder may again be the subject of
an Option under the Plan.  The Board, in its sole discretion, may permit the
exercise of any Option as to full Shares or fractional Shares.  Proceeds from
the sale of Shares under Options shall constitute general funds of the Company.

     6.  TERMS AND CONDITIONS OF OPTIONS.

         (a)  At the time of grant, the Board shall determine whether the
Options granted are to be ISOs or Non-statutory Options and shall enter into
stock option agreements with the recipients accordingly.  All Options granted
shall be authorized by the Board and, within a reasonable time after the date of
grant, shall be evidenced by stock option agreements in writing ("Stock Option
Agreements"), in such form and containing such terms and conditions not
inconsistent with the provisions of this Plan as the Board shall from time to
time determine.  Any action under paragraph 12 may be reflected in an amendment
to or restatement of such Stock Option Agreements.

         (b)  The Board may grant Options having terms and provisions which
vary from those specified in the Plan if such Options are granted in
substitution for, or in connection with the assumption of, existing options
granted by another corporation and assumed or otherwise agreed to be provided
for by the Company pursuant to or by reason of a transaction involving a
corporate merger, consolidation, acquisition of property or stock, separation,
reorganization or liquidation to which the Company is a party.

     7.  PRICE.  The option price per Share (the "Option Price") of each Option
granted under the Plan shall be determined by the Board; PROVIDED, HOWEVER, the
Option Price of each ISO granted under the Plan shall not be less than the fair
market value (determined without regard to any restrictions other than a
restriction which, by its terms, will never lapse) of a Share on  the date of
grant of such Option.  An Option shall be considered granted on the date the
Board acts to grant the Option or such later date as the Board shall specify.

     8.  OPTION PERIOD.  The period during which the Option may be exercised
(the "Option Period") shall be determined by the Board; PROVIDED, HOWEVER, any
ISO granted under the Plan shall have an Option Period which does not exceed 10
years from the date the ISO is granted.

     9.  NON-TRANSFERABILITY OF OPTIONS.  An Option shall not be transferable
by the Optionee otherwise than by will or the laws of descent and distribution
and may be exercised, during the lifetime of the Optionee, only by him or by his
guardian or legal representative.  Notwithstanding the foregoing, an Optionee
may transfer a Non-Statutory Option to members of his or her immediate family
(as defined in Rule 16a-1 promulgated under the 1934 Act), to one or more trusts
for the benefit of such family members or to partnerships in which such family
members are the only partners if (a) the stock option agreement with respect to
such Non-Statutory Option as approved by the Committee expressly so provides and
(b) the Optionee does not receive any consideration for the transfer. 
Non-Statutory Options held by such transferees are subject to the same terms and
conditions that applied to such Non-Statutory Options immediately prior to
transfer.

    10.  EXERCISE OF OPTIONS.  

         (a)  Options granted hereunder will be exercisable upon the terms and
conditions and in accordance with the vesting percentages determined by the
Board in its sole discretion.  Notwithstanding the foregoing or the terms and
conditions of any Stock Option Agreement to the


                                          3

<PAGE>

contrary, (i) in the event of the Optionee's termination of employment as
specified in subparagraph 11(a), the Options shall be exercisable to the extent
and for the period specified in subparagraph 11(a); (ii) in the event of the
Optionee's termination of employment as a result of disability or death as
specified in subparagraph 11(b), the Options shall be exercisable to the extent
and for the period specified in subparagraph 11(b); (iii) in the event of a
merger, reorganization or sale of all or substantially all of the assets of the
Company as specified in subparagraph 12(c), the Options shall be exercisable to
the extent and for the period specified in subparagraph 12(c); and (iv) in the
event of a change in control, as defined herein, all Options held by Optionee
shall become exercisable for the period specified in subparagraph 12(d).  

         (b)  An Option shall be exercisable only upon delivery of a written
notice to the Board, any member of the Board, the Company's Treasurer, or any
other officer of the Company designated by the Board to accept such notices on
its behalf, specifying the number of Shares for which it is exercised.

         (c)  Within five business days following the date of exercise of an
Option, the Optionee or other person exercising the Option shall make full
payment of the Option Price (i) in cash; (ii) with the consent of the Board, by
tendering previously acquired Shares (valued at their fair market value as of
the date of tender); (iii) with the consent of the Board, and to the extent
permitted by applicable law, with a full recourse promissory note of the
Optionee for the portion of the Option Price in excess of the par value of
Shares subject to the  Option, under terms and conditions determined by the
Board and in cash for the par value of the Shares; (iv) with the consent of the
Board, any combination of (i), (ii), or (iii); or (v) with the consent of the
Board, if the Shares subject to the Option have been registered under the
Securities Act of 1933, as amended (the "1933 Act"), and there is a regular
public market for the Shares, by delivering to the Company on the date of
exercise of the Option written notice of exercise together with:

              (A)  written instructions to forward a copy of such
         notice of exercise to a broker or dealer as defined in
         Section 3(a)(4) and 3(a)(5) of the Securities Exchange Act
         of 1934, as amended (the "1934 Act"), and designated in such
         notice ("Broker"), and to deliver to the specified account
         maintained with the Broker by the person exercising the
         Option a certificate for the Shares purchased upon the
         exercise of the Option, and

              (B)  a copy of irrevocable instructions to the Broker
         to deliver promptly to the Company a sum equal to the
         purchase price of the Shares purchased upon exercise of the
         Option.

         (d)  The Optionee or other person exercising such Option shall pay to
the Company an amount equal to the withholding amount required to be made less
any amount withheld by the Company under paragraph 17.

    If previously acquired Shares are to be used to pay the exercise price of
an ISO, the Company prior to such payment must be furnished with evidence
satisfactory to it that the acquisition of such Shares and their transfer in
payment of the exercise price satisfy the requirements of Section 422 of the
Code and other applicable laws.

    11.  TERMINATION OF EMPLOYMENT.

         (a)  Upon termination of an Optionee's employment with the Company
Group, other than termination of employment by reason of disability or death or
for cause, the Optionee shall have 30 days after the date of termination of
employment (but not later than the expiration date of the Stock Option
Agreement) to exercise all Options held by him or her to the extent the same
were exercisable on the date of termination; PROVIDED, HOWEVER, if such
termination is due to the Optionee's retirement with the consent of the Company,
such Option shall then be exercisable to the extent of 100% of the Shares
subject thereto.  The Board shall determine in each case whether a termination
of employment shall be considered a retirement with the consent of the Company
and, subject to applicable law, whether a leave of absence shall be considered a
termination of employment.  The Board may cancel an Option during the 30-day 
period after termination of employment referred to in this paragraph if the
Optionee engages in employment or activities contrary, in the sole opinion of
the Board, to the best interests of the Company or any parent or subsidiary of
the Company.

         (b)  Upon termination of an Optionee's employment by reason of
disability, as defined in subparagraph 27(a) of this Plan, or death, the
Optionee or the Optionee's personal representative, or the person or persons to
whom his or her rights under the Options pass by will or the laws of descent or
distribution, shall have one year after the date of termination of employment by
reason of disability or death (but not later than the expiration date of the
Stock Option Agreement) to exercise all Options held by Optionee to the extent
the same were exercisable on the date of the Optionee's termination of
employment; PROVIDED, HOWEVER, the Board may, but shall not be required to,
permit, in its discretion, the exercise of all or any portion of any Option
granted to such Optionee not otherwise exercisable.

         (c)  Upon termination of an Optionee's employment for cause, as
defined herein, all Options held by such Optionee shall terminate effective on
the date of termination of employment.

    12.  STOCK SPLITS; MERGERS; REORGANIZATIONS; SALE OF ASSETS.

         (a)  In the event of a stock split, stock dividend, combination or
exchange of shares, exchange for other securities, reclassification,
reorganization, redesignation or other change in the Company's capitalization,
the aggregate number of Shares for which Options may be granted under this Plan,
the number of Shares subject to outstanding Options and the Option Price of the
Shares subject to outstanding Options shall be proportionately adjusted or
substituted to reflect the same.  The Board shall make such other adjustments to
the Options, the provisions of the Plan and the Stock Option Agreements as may
be appropriate and equitable, which adjustments may provide for the elimination
of fractional Shares.

         (b)  In the event of a change of the Common Stock resulting from a
merger or similar reorganization as to which the Company is the surviving
corporation, the number and kind of Shares which thereafter may be purchased
pursuant to an Option under the Plan and the number and kind of Shares then
subject to Options granted hereunder and the price per Share thereof shall


                                          5

<PAGE>

be appropriately adjusted in such manner as the Board may deem equitable to
prevent dilution or enlargement of the rights available or granted hereunder.  
 
         (c)  Except as otherwise determined by the Board, a merger or a
similar reorganization which the Company does not survive (other than a merger
or similar reorganization involving only a change in the state of incorporation
or an internal reorganization not involving a change in control as defined
herein), or a sale of all or substantially all of the assets of the Company,
shall cause every Option hereunder to terminate, to the extent not then
exercised, unless any surviving entity agrees to assume the obligations
hereunder; provided, however, that, in the case of such a merger or similar
reorganization, or such a sale of all or substantially all of the assets of the
Company, if there is no such assumption, the Board may provide that some or all
of the unexercised portion of any one or more of the outstanding Options shall
be immediately exercisable and vested as of such date prior to such merger,
similar reorganization or sale of assets as the Board determines.

         (d)  If a change in control, as defined herein, occurs, all
outstanding options granted under this Plan shall then be immediately
exercisable to the extent of 100% of the Shares subject thereto notwithstanding
any contrary waiting or vesting periods specified in this Plan or in any
applicable Stock Option Agreement.

    13.  SALE OF OPTION SHARES.  If any class of equity securities of the
Company is registered pursuant to Section 12 of the 1934 Act, any Optionee or
other person exercising the Option who is subject to Section 16 of the 1934 Act
by virtue of his or her relationship to the Company shall not sell or otherwise
dispose of the Shares subject to Option unless at least six months have elapsed
from the date of grant of the Option.

    14.  RIGHTS AS SHAREHOLDER.  The Optionee shall have no rights as a
shareholder with respect to any Shares covered by an Option until the date of
issuance of a stock certificate to the Optionee for such Shares.

    15.  NO CONTRACT OF EMPLOYMENT.  Nothing in the Plan or in any Option or
Stock Option Agreement shall confer on any Optionee any right to continue in the
employ or service of the Company or any parent or subsidiary of the Company or
interfere with the right of the Company to terminate such Optionee's employment
or other services at any time.  The establishment of the Plan shall in no way,
now or hereafter, reduce, enlarge or modify the employment relationship between
the Company or any parent or subsidiary of the Company and the Optionee. 
Options granted under the Plan shall not be affected by any change of duties or
position of the Optionee with the Company.

    16.  AGREEMENTS AND REPRESENTATIONS OF OPTIONEES.  As a condition to the
exercise of an Option,  the Board may, in its sole determination, require the
Optionee to represent in writing  that the Shares being purchased are being
purchased only for investment and without any present intent at the time of the
acquisition of such Shares to sell or otherwise dispose of the same.

    17.  WITHHOLDING TAXES.  The Company's obligation to deliver Shares upon
exercise of an Option shall be subject to the Optionee's satisfaction of all
applicable federal, state or local tax withholding obligations.  The Company
shall have the right to withhold from any salary, wages,


                                          6

<PAGE>

or other compensation for services payable by the Company to or with respect to
an Optionee, amounts sufficient to satisfy any federal, state or local
withholding tax liability attributable to such Optionee's (or any beneficiary's
or personal representative's) receipt or disposition of Shares purchased under
any Option or to take any such other action as it deems necessary to enable it
to satisfy any such tax withholding obligations.  The Board, in its sole
discretion, may permit Optionees to elect to have Shares that would be acquired
upon exercise of Options (valued at their fair market value as of the date of
exercise) withheld by the Company in satisfaction of such Optionees' withholding
tax liabilities.

    18.  EXCHANGES.  The Board may permit the voluntary surrender of all or a
portion of any Option granted under the Plan to be conditioned upon the granting
to the Optionee of a new Option for the same or a different number of Shares as
the Option surrendered, or may require such voluntary surrender as a condition
precedent to a grant of a new Option to such Optionee.  Subject to the
provisions of the Plan, such new Option shall be exercisable at the same price,
during such period and on such other terms and conditions as are specified by
the Board at the time the new Option is granted.  Upon surrender, the Options
surrendered shall be cancelled and the Shares previously subject to them shall
be available for the grant of other Options.

    19.  REPURCHASE OF SHARES BY THE COMPANY.  Any Shares purchased or acquired
upon exercise of an Option may, in the sole discretion of the Board, be subject
to repurchase by or forfeiture to the Company if and to the extent and at the
repurchase price, if any, specifically set forth in the Stock Option Agreement
pursuant to which the Shares were purchased or acquired.  Certificates
representing Shares subject to such repurchase or forfeiture may be subject to
such escrow and stock legending provisions as may be set forth in the Stock
Option Agreement pursuant to which the Shares were purchased or acquired.  

    20.  CONFIDENTIALITY AGREEMENTS.  Upon the Company's request, each Optionee
shall execute, prior to or contemporaneously with the grant of any Option
hereunder, the  Company's then standard form of agreement relating to
nondisclosure of confidential information, noncompetition and/or assignment of
inventions and related matters.  

    21.  COMPLIANCE WITH LAWS AND REGULATIONS.  The Plan, the grant and
exercise of Options thereunder, and the obligation of the Company to sell and
deliver the Shares under such Options, shall be subject to all applicable
federal and state laws, rules and regulations and to such approvals by any
government or regulatory agency as may be required.  Options issued under the
Plan shall not be exercisable prior to (i) the date upon which the Company shall
have registered the Shares for which Options may be issued hereunder under the
1933 Act, and (ii) the completion of any registration or qualification of such
Shares under state law, or any ruling or regulation of any governmental body
which the Company shall, in its sole discretion, determine to be necessary or
advisable in connection therewith, or alternatively, unless the Company shall
have received an opinion from counsel to the Company stating that the exercise
of such Options may be effected without registering the Shares subject to such
Options under the l933 Act, or under state or other law.

    22.  ASSUMPTION.  The Plan may be assumed by the successors and assigns of
the Company.


                                          7

<PAGE>

    23.  EXPENSES.  All expenses and costs in connection with administration of
the Plan shall be borne by the Company.

    24.  AMENDMENT, MODIFICATION AND TERMINATION OF THE PLAN.  The Board may
terminate, amend or modify the Plan at any time without further action on the
part of the shareholders of the Company; PROVIDED, HOWEVER, that (a) in no event
shall any amendment be made to the Plan which would cause the ISOs granted
hereunder to fail to qualify as incentive stock options under the Code; (b) any
amendment to the Plan which requires the approval of the shareholders of the
Company under the Code or the regulations promulgated thereunder shall be
subject to approval by the shareholders of the Company in accordance with the
Code or such regulations; and (c) any amendment to the Plan which requires the
approval of the shareholders of the Company under the rules promulgated under
Section 16 of the 1934 Act shall be subject to the approval of the shareholders
of the Company in accordance with such rules.  No amendment, modification or
termination of the Plan shall in any manner adversely affect any Option
previously granted to an Optionee under the Plan without the consent of the
Optionee or the transferee of such Option.

    With the consent of the Optionee affected, the Board may amend outstanding
Options or related agreements in a manner not inconsistent with the Plan.  The
Board shall have the right to amend or modify the terms and provisions of the
Plan and of any  outstanding ISO's granted under the Plan to the extent
necessary to qualify any or all such Options for such favorable federal income
tax treatment (including deferral of taxation upon exercise) as may be afforded
incentive stock options under Section 422 of the Code.

    25.  TERM OF PLAN.  The Plan shall become effective on the Effective Date. 
The Plan shall terminate on the tenth anniversary of the Effective Date, or such
earlier date as may be determined by the Board.  Termination of the Plan,
however, shall not affect the rights of Optionees under Options previously
granted to them, and all unexpired Options shall continue in force and operation
after termination of the Plan except as they may lapse or be terminated by their
own terms and conditions.

    26.  LIMITATION OF LIABILITY.  The liability of the Company under this Plan
or in connection with any exercise of an Option is limited to the obligations
expressly set forth in the Plan and in any Stock Option Agreements, and no term
or provision of this Plan or of any Stock Option Agreements shall be construed
to impose any further or additional duties, obligations or costs on the Company
not expressly set forth in the Plan or the Stock Option Agreements.

    27.  DEFINITIONS.

         (a)  DISABILITY.  "Disability," as used herein, shall mean a physical
or mental condition resulting from bodily injury, disease, or mental disorder
which renders the Optionee incapable of continuing the Optionee's usual and
customary employment or service with the Company Group.

         (b)  FAIR MARKET VALUE.  If the Shares are publicly traded, the term
"fair market value" as used in this Plan shall mean (a) the closing price quoted
in the NASDAQ National Market System, if the shares are so quoted, (b) the last
quote reported by NASDAQ for small-cap


                                          8

<PAGE>

issues, if the shares are so quoted, (c) the mean between the bid and asked
prices as reported by NASDAQ, if the Shares are so quoted, or (d) if the Shares
are listed on a securities exchange, the closing price at which the Shares are
quoted on such exchange, in each case at the close of the date immediately
before the Option is granted or, if there be no quotation or sale on that date,
the next previous date on which the Shares were quoted or traded.  In all other
cases, the fair market value shall be determined by and in accordance with
procedures established in good faith by the Board and with respect to ISOs,
conforming to regulations issued by the Internal Revenue Service regarding
incentive stock options.
 
         (c)  KEY ASSOCIATES.  The term "key associates" shall include those
executive, administrative, operational and managerial employees who are
determined by the Board to be eligible for Options under the Plan.

         (d)  PARENT AND SUBSIDIARY.  The terms "subsidiary" and "parent" as
used in the Plan shall have the respective meanings set forth in sections 424(f)
and (e) of the Code.

         (e)  TERMINATION FOR CAUSE.  The term "termination of employment for
cause" shall mean termination of employment for (a) the commission of an act of
dishonesty, including but not limited to misappropriation of funds or property
of the Company; (b) the engagement in activities or conduct injurious to the
reputation of the Company; (c) the conviction or entry of a guilty or no contest
plea to a misdemeanor involving an act of moral turpitude or a felony; (d) the
violation of any of the terms and conditions of any written agreement the
Optionee may have from time to time with the Company Group (following 30 days'
written notice from the Company specifying the violation and the employee's
failure to cure such violation within such 30-day period); or (e) any refusal to
comply with the written directives, policies or regulations established from
time to time by the Board.

         (f)  CHANGE IN CONTROL.  A "change in control" shall be deemed to have
taken place if, as a result of a tender offer, merger, consolidation, sale of
assets or contested election, or any combination of the foregoing transactions
(a "Transaction"), the persons who were directors of the Company immediately
before the Transaction shall cease to constitute a majority of the Board of
Directors of the Company or of any successor to the Company; provided, however,
that any Transaction shall not be deemed to be a change in control if the
Transaction causing such change shall have been approved by the affirmative vote
of at least a majority of the members of the Board of Directors of the Company
in office immediately prior to the change in control.
