                         ACCESS RADIOLOGY CORPORATION

                                1994 STOCK PLAN
                                ---------------

     1.   Purpose. The purpose of the ACCESS Radiology Corporation 1994 Stock
          -------
Plan (the "Plan") is to encourage superior performance by key employees of
ACCESS Radiology Corporation (the "Company") and of any present or future parent
or subsidiary of the Company (collectively, "Related Corporations") and other
individuals who render services to the Company or a Related Corporation, by
providing opportunities to participate in the ownership of the Company and its
future growth through (a) the grant of options which qualify as "incentive stock
options" ("ISOs") under Section 422(b) of the Internal Revenue Code of 1986, as
amended (the "Code"); (b) the grant of options which do not qualify as ISOs
("Non-Qualified Options"); (c) awards of stock in the Company ("Awards"); and
(d) opportunities to make direct purchases of stock in the Company
("Purchases"). Both ISOs and Non-Qualified Options are referred to hereafter
individually as an "Option" and collectively as "Options." Options, Awards and
authorizations to make Purchases are referred to hereafter collectively as
"Stock Rights." As used herein, the terms "parent" and "subsidiary" mean "parent
corporation" and "subsidiary corporation," respectively, as those terms are
defined in Section 424 of the Code.

     2.   Administration of the Plan.
          --------------------------

          A.   Board or Committee Administration. The Plan shall be administered
               ---------------------------------
     by the Board of Directors of the Company (the "Board") or by a committee
     appointed by the Board (the "Committee"); provided that the Plan shall be
     administered to the extent required by Rule 16b-3 promulgated under the
     Securities Exchange Act of 1934 (the "Exchange Act") or any successor
     provision ("Rule 16b-3"), by a disinterested administrator or
     administrators within the meaning of Rule 16b-3. Hereinafter, all
     references in this Plan to the "Committee" shall mean the Board if no
     Committee has been appointed. Subject to the ratification of the grant or
     authorization of each Stock Right by the Board (if so required by
     applicable state law), and subject to the terms of the Plan, the Committee
     shall have the authority to (i) determine to whom (from among the class of
     employees eligible under paragraph 3 to receive ISOs) ISOs shall be
     granted, and to whom (from among the class of individuals and entities
     eligible under paragraph 3 to receive Non-Qualified Options and
<PAGE>

     Awards and to make Purchases) Non-Qualified Options, Awards and
     authorizations to make Purchases may be granted; (ii) determine the time or
     times at which Options or Awards shall be granted or Purchases made; (iii)
     determine the purchase price of shares subject to each Option or Purchase,
     which prices shall not be less than the minimum price specified in
     paragraph 6; (iv) determine whether each Option granted shall be an ISO or
     a Non-Qualified Option; (v) determine (subject to paragraph 7) the time or
     times when each Option shall become exercisable, the conditions (if any)
     under which such exercisability may be accelerated, and the duration of the
     exercise period; (vi) extend the period during which outstanding Options
     may be exercised; (vii) determine whether restrictions such as repurchase
     options are to be imposed on shares subject to Options, Awards and
     Purchases and the nature of such restrictions, if any, and (viii) interpret
     the Plan and prescribe and rescind rules and regulations relating to it. If
     the Committee determines to issue a Non-Qualified Option, it shall take
     whatever actions it deems necessary, under Section 422 of the Code and the
     regulations promulgated thereunder, to ensure that such Option is not
     treated as an ISO. The interpretation and construction by the Committee of
     any provisions of the Plan or of any Stock Right granted under it shall be
     final unless otherwise determined by the Board. The Committee may from time
     to time adopt such rules and regulations for carrying out the Plan as it
     may deem advisable. No member of the Board or the Committee shall be liable
     for any action or determination made in good faith with respect to the Plan
     or any Stock Right granted under it.

          B.   Committee Actions. The Committee may select one of its members as
               -----------------
     its chairman, and shall hold meetings at such time and places as it may
     determine. A majority of the Committee shall constitute a quorum and acts
     of a majority of the members of the Committee at a meeting at which a
     quorum is present, or acts reduced to or approved in writing by all the
     members of the Committee (if consistent with applicable state law); shall
     be the valid acts of the Committee. From time to time the Board may
     increase the size of the Committee and appoint additional members thereof,
     remove members (with or without cause) and appoint new members in
     substitution therefor, fill vacancies however caused, or remove all members
     of the Committee and thereafter directly administer the Plan.

          C.   Grant of Stock Rights to Board Members. Subject to the provisions
               --------------------------------------
     of the first sentence of paragraph 2(A) above, if applicable, Stock Rights
     may be granted to members of the Board. All grants of Stock

                                      -2-
<PAGE>

     Rights to members of the Board shall in all other respects be made in
     accordance with the provisions of this Plan applicable to other eligible
     persons. Consistent with the provisions of the first sentence of Paragraph
     2(A) above, members of the Board who either (i) are eligible to receive
     grants of Stock Rights pursuant to the Plan or (ii) have been granted Stock
     Rights may vote on any matters affecting the administration of the Plan or
     the grant of any Stock Rights pursuant to the Plan, except that no such
     member shall act upon the granting to himself or herself of Stock Rights,
     but any such member may be counted in determining the existence of a quorum
     at any meeting of the Board during which action is taken with respect to
     the granting to such member of Stock Rights.

     3.   Eligible Employees and Others. ISOs may be granted only to employees
          -----------------------------
of the Company or any Related Corporation. Non-Qualified Options, Awards and
authorizations to make Purchases may be granted to any employee, officer or
director (whether or not also an employee) or consultant of the Company or any
Related Corporation, or any member of the Company's Medical and Technical
Advisory Board. The Committee may take into consideration a recipient's
individual circumstances in determining whether to grant a Stock Right. The
granting of any Stock Right to any individual or entity shall neither entitle
that individual or entity to, nor disqualify such individual or entity from,
participation in any other grant of Stock Rights.

     4.   Stock. The stock subject to Stock Rights shall be authorized but
          -----
unissued shares of Common Stock of the Company, par value $.01 per share (the
"Common Stock"), or shares of Common Stock reacquired by the Company in any
manner. The aggregate number of shares which may be issued pursuant to the Plan
is 4,950,000, subject to adjustment as provided in paragraph 13. If any Stock
Right granted under the Plan shall expire or terminate for any reason without
having been exercised in full or shall cease for any reason to be exercisable in
whole or in part or shall be repurchased by the Company, the shares of Common
Stock subject to such Stock Right shall again be available for grants of Stock
Rights under the Plan. Shares of Common Stock underlying Stock Rights granted in
assumption of, or in substitution for, outstanding options or other rights
previously granted by a company acquired by the Company or with which the
Company combines shall not, except in the case of shares with respect to which
Stock Rights are granted to employees who are officers or directors of the
Company for purposes of Section 16 of the Exchange Act, be counted against
shares of Common Stock available for the grant of Stock Rights under the Plan.

     5.   Granting of Stock Rights. Stock Rights may be
          ------------------------

                                      -3-
<PAGE>

granted under the Plan at any time on or after August 11, 1994 and prior to
August 10, 2004. The date of grant of a Stock Right under the Plan will be the
date specified by the Committee at the time it grants the Stock Right; provided,
however, that such date shall not be prior to the date on which the Committee
acts to approve the grant.

     6.   Minimum Option Price; ISO Limitations.
          -------------------------------------

          A.   Price for Non-Qualified Options, Awards and Purchases. The
               -----------------------------------------------------
     exercise price per share specified in the agreement relating to each Non-
     Qualified Option granted, and the purchase price per share of stock granted
     in any Award or authorized as a Purchase under the Plan shall in no event
     be less than the minimum legal consideration required therefor under the
     laws of any jurisdiction in which the Company or its successors in interest
     may be organized.

          B.   Price for ISOs. The exercise price per share specified in the
               --------------
     agreement relating to each ISO granted under the Plan shall not be less
     than the fair market value per share of Common Stock on the date of such
     grant. In the case of an ISO to be granted to an employee owning stock
     possessing more than ten percent (10%) of the total combined voting power
     of all classes of stock of the Company or any Related Corporation, the
     price per share specified in the agreement relating to such ISO shall not
     be less than one hundred ten percent (110%) of the fair market value per
     share of Common Stock on the date of grant. For purposes of determining
     stock ownership under this paragraph, the rules of Section 424(d) of the
     Code shall apply.

          C.   $100,000 Annual Limitation on ISO Vesting. Each eligible employee
               -----------------------------------------
     may be granted Options treated as ISOs only to the extent that, in the
     aggregate under this Plan and all incentive stock option plans of the
     Company and any Related Corporation, ISOs do not become exercisable for the
     first time by such employee during any calendar year with respect to stock
     having a fair market value (determined at the time the ISOs were granted)
     in excess of $100,000. The Company intends to designate any Options granted
     in excess of such limitation as Non-Qualified Options.

          D.   Determination of Fair Market Value. If, at the time an Option is
               ----------------------------------
     granted under the Plan, the Company's Common Stock is publicly traded,
     "fair market value" shall be determined as of the last business day for
     which the prices or quotes discussed in this sentence are available prior
     to the date such Option is granted and

                                      -4-
<PAGE>

     shall mean (i) the average (on that date) of the high and low prices of the
     Common Stock on the principal national securities exchange on which the
     Common Stock is traded, if the Common Stock is then traded on a national
     securities exchange; or (ii) the last reported sale price (on that date) of
     the Common Stock on the Nasdaq National Market, if the Common Stock is not
     then traded on a national securities exchange; or (iii) the closing bid
     price (or average of bid prices) last quoted (on that date) by an
     established quotation service for over-the-counter securities, if the
     Common Stock is not reported on the Nasdaq National Market. If the Common
     Stock is not publicly traded at the time an Option is granted under the
     Plan, "fair market value" shall mean the fair value of the Common Stock as
     determined by the Committee after taking into consideration all factors
     which it deems appropriate, including, without limitation, recent sale and
     offer prices of the Common Stock in private transactions negotiated at
     arm's length.

     7.   Option Duration. Subject to earlier termination as provided in
          ---------------
paragraphs 9 and 10 or in the agreement relating to such Option, each Option
shall expire on the date specified by the Committee, but not more than (i) ten
years from the date of grant in the case of Options generally and (ii) five
years from the date of grant in the case of ISOs granted to an employee owning
stock possessing more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or any Related Corporation, as determined
under paragraph 6(B). Subject to earlier termination as provided in paragraphs 9
and 10, the term of each ISO shall be the term set forth in the original
instrument granting such ISO, except with respect to any part of such ISO that
is converted into a Non-Qualified Option pursuant to paragraph 16.

     8.   Exercise of Option.  Subject to the provisions of paragraphs 9 through
          ------------------
 12, each Option granted under the Plan shall be exercisable as follows:

          A.   Vesting. Each Option shall be exercisable at such times and
               -------
     subject to such terms and conditions as the Committee may, in its sole
     discretion, specify in the agreement granting each Option or otherwise. The
     Committee may impose such conditions with respect to the exercise of
     Options, including without limitation any relating to the application of
     federal or state securities laws, as it may deem necessary or advisable.

          B.   Acceleration of Vesting. The Committee shall have the right to
               -----------------------
     accelerate the date that any installment of any Option becomes exercisable;
     provided that the Committee shall not, without the consent of an optionee,
     accelerate the permitted exercise date of any installment

                                      -5-
<PAGE>

     of any Option granted to any employee as an ISO (and not previously
     converted into a Non-Qualified Option pursuant to paragraph 16) if such
     acceleration would violate the annual vesting limitation contained in
     Section 422(d) of the Code, as described in paragraph 6(C).

     9.   Termination of Employment. If an ISO optionee ceases to be employed by
          -------------------------
the Company and all Related Corporations other than by reason of death or
disability as defined in paragraph 10, no further installments of his or her
ISOs shall become exercisable, and his or her ISOs shall terminate on the
earlier of (a) ninety (90) days after the date of termination of his or her
employment, or (b) their specified expiration dates, except to the extent that
such ISOs (or unexercised installments thereof) have been converted into Non-
Qualified Options pursuant to paragraph 16. For purposes of this paragraph 9,
employment shall be considered as continuing uninterrupted during any bona fide
leave of absence (such as those attributable to illness, military obligations or
governmental service) provided that the period of such leave does not exceed 90
days or, if longer, any period during which such optionee's right to
reemployment is guaranteed by statute. A bona fide leave of absence with the
written approval of the Committee shall not be considered an interruption of
employment under this paragraph 9, provided that such written approval
contractually obligates the Company or any Related Corporation to continue the
employment of the optionee after the approved period of absence. ISOs granted
under the Plan shall not be affected by any change of employment within or among
the Company and Related Corporations, so long as the optionee continues to be an
employee of the Company or any Related Corporation. Nothing in the Plan shall be
deemed to give any grantee of any Stock Right the right to be retained in
employment or other service by the Company or any Related Corporation for any
period of time.

     10.  Death; Disability.
          -----------------

          A.   Death. If an ISO optionee ceases to be employed by the Company
               -----
     and all Related Corporations by reason of his or her death, any ISO owned
     by such optionee may be exercised, to the extent otherwise exercisable on
     the date of death, by the estate, personal representative or beneficiary
     who has acquired the ISO by will or by the laws of descent and
     distribution, until the earlier of (i) the specified expiration date of the
     ISO or (ii) 180 days from the date of the optionee's death.

          B.   Disability. If an ISO optionee ceases to be employed by the
               ----------
     Company and all Related Corporations by reason of his or her disability,
     such optionee shall have the right to exercise any ISO held by him or her
     on the

                                      -6-
<PAGE>

     date of termination of employment, for the number of shares for which he or
     she could have exercised it on that date, until the earlier of (i) the
     specified expiration date of the ISO or (ii) 180 days from the date of the
     termination of the optionee's employment. For the purposes of the Plan, the
     term "disability" shall mean "permanent and total disability" as defined in
     Section 22(e)(3) of the Code or any successor statute.

     11.  Assignability. No Stock Right shall be assignable or transferable by
          -------------
the grantee except by will, by the laws of descent and distribution or, in the
case of Non-Qualified Options only, pursuant to a qualified domestic relations
order as defined by the Code or Title I of the Employee Retirement Income
Security Act, or the rules thereunder. The designation of a beneficiary by a
grantee does not constitute a transfer. Except as set forth in the previous
sentence, during the lifetime of a grantee each Stock Right shall be exercisable
only by such grantee.

     12.  Terms and Conditions of Options. Options shall be evidenced by
          -------------------------------
instruments (which need not be identical) in such forms as the Committee may
from time to time approve. Such instruments shall conform to the terms and
conditions set forth in paragraphs 6 through 11 hereof and may contain such
other provisions as the Committee deems advisable which are not inconsistent
with the Plan, including restrictions applicable to shares of Common Stock
issuable upon exercise of Options. The Committee may specify that any
Non-Qualified Option shall be subject to the restrictions set forth herein with
respect to ISOs, or to such other termination and cancellation provisions as the
Committee may determine. The Committee may from time to time confer authority
and responsibility on one or more of its own members and/or one or more officers
of the Company to execute and deliver such instruments. The proper officers of
the Company are authorized and directed to take any and all action necessary or
advisable from time to time to carry out the terms of such instruments.

     13.  Adjustments. In the event that the Committee determines that any
          -----------
dividend or other distribution (whether in the form of cash, Common Stock, other
securities, or other property), recapitalization, stock split, reverse stock
split, reorganization, merger, consolidation, split-up, spin-off, combination,
repurchase, or exchange of Common Stock or other securities of the Company,
issuance of warrants or other rights to purchase Common Stock or other
securities of the Company, or other similar corporate transaction or event
affects the Common Stock such that an adjustment is determined by the Committee
to be appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Plan, then the
Committee shall, in such manner as it may deem equitable, adjust

                                      -7-
<PAGE>

any or all of (i) the number of shares of Common Stock or other securities of
the Company (or number and kind of other securities or property) with respect to
which Stock Rights may be granted, (ii) the number of shares of Common Stock or
other securities of the Company (or number and kind of other securities or
property) subject to outstanding Stock Rights, and (iii) the grant or exercise
price with respect to any Stock Rights or, if deemed appropriate, make provision
for a cash payment to the holder of an outstanding Stock Right; provided, in
each case, that with respect to ISOs no such adjustment shall be authorized to
the extent that such authority would cause the Plan to violate Section 422(b)(1)
of the Code, as from time to time amended.

     14.  Means of Exercising Options. An Option (or any part or installment
          ---------------------------
thereof) shall be exercised by giving written notice to the Company at its
principal office address, or to such transfer agent as the Company shall
designate. Such notice shall identify the Option being exercised and specify the
number of shares as to which such Option is being exercised, accompanied by full
payment of the purchase price therefor either (a) in United States dollars in
cash or by check, (b) at the discretion of the Committee, through delivery of
shares of Common Stock having a fair market value equal as of the date of the
exercise to the cash exercise price of the Option (provided that any such shares
of stock acquired through exercise of options or otherwise as compensation from
the Company shall have been held for at least six months), (c) at the discretion
of the Committee, by delivery of the grantee's personal recourse note bearing
interest payable not less than annually at no less than 100% of the lowest
applicable Federal rate, as defined in Section 1274(d) of the Code, (d) at the
discretion of the Committee and consistent with applicable law, through the
delivery of an assignment to the Company of a sufficient amount of the proceeds
from the sale of the Common Stock acquired upon exercise of the Option and an
authorization to the broker or selling agent to pay that amount to the Company,
which sale shall be at the participant's direction at the time of the exercise,
or (e) at the discretion of the Committee, by any combination of (a), (b), (c)
above. If the Committee exercises its discretion to permit payment of the
exercise price of an ISO by means of the methods set forth in clauses (b), (c),
(d) or (e) of the preceding sentence, such discretion shall be exercised in
writing at the time of the grant of the ISO in question. The holder of an Option
shall not have the rights of a shareholder with respect to the shares covered by
such Option until the date of issuance of a stock certificate to such holder for
such shares. Except as expressly provided above in paragraph 13 with respect to
changes in capitalization and stock dividends, no adjustment shall be made for
dividends or similar rights for which the record date is before the date such
stock certificate is issued.

                                      -8-
<PAGE>

     15.  Term and Amendment of Plan. This Plan was adopted by the Board on
          --------------------------
August 11, 1994, subject, with respect to the validation of ISOs granted under
the Plan, to the approval of the Plan by the stockholders of the Company at the
next Meeting of Stockholders or, in lieu thereof, by written consent. If the
approval of stockholders is not obtained prior to August 11, 1995, any grants of
ISOs under the Plan made prior to that date will be rescinded. The Plan shall
expire at the end of the day on August 10, 2004 (except as to Options
outstanding on that date). Subject to the provisions of paragraph 5 above,
Options may be granted under the Plan prior to the date of stockholder approval
of the Plan. The Board may terminate or amend the Plan in any respect at any
time, except that, without the approval of the stockholders obtained within 12
months before or after the Board adopts a resolution authorizing any of the
following actions: (a) the total number of shares that may be issued under the
Plan may not be materially increased (except by adjustment pursuant to paragraph
13); (b) the benefits accruing to participants under the Plan may not be
materially increased; (c) the requirements as to eligibility for participation
in the Plan may not be materially modified; (d) the provisions of paragraph 3
regarding eligibility for grants of ISOs may not be modified; (e) the provisions
of paragraph 6(B) regarding the exercise price at which shares may be offered
pursuant to ISOs may not be modified (except by adjustment pursuant to paragraph
13); (f) the expiration date of the Plan may not be extended; and (g) the Board
may not take any action which would cause the Plan to fail to comply with Rule
16b-3. Except as otherwise provided in this paragraph 15, in no event may action
of the Board or stockholders alter or impair the rights of a grantee, without
such grantee's consent, under any Option previously granted to such grantee.

     16.  Conversion of ISOs into Non-Qualified Options. The Committee, at
          ---------------------------------------------
the written request or with the written consent of any optionee, may in its
discretion take such actions as may be necessary to convert such optionee's ISOs
(or any installments or portions of installments thereof) that have not been
exercised on the date of conversion into Non-Qualified Options at any time prior
to the expiration of such ISOs, regardless of whether the optionee is an
employee of the Company or a Related Corporation at the time of such conversion.
Such actions may include, but shall not be limited to, extending the exercise
period or reducing the exercise price of any portion of such ISOs. At the time
of such conversion, the Committee (with the consent of the optionee) may impose
such conditions on the exercise of the resulting Non-Qualified Options as the
Committee in its discretion may determine, provided that such conditions shall
not be inconsistent with this Plan. Nothing in the Plan shall be deemed to give
any optionee the right to have such optionee's ISOs converted into

                                      -9-
<PAGE>

Non-Qualified Options, and no such conversion shall occur until and unless the
Committee takes appropriate action.

     17.  Application of Funds. The proceeds received by the Company from the
          --------------------
sale of shares pursuant to Options granted and Purchases authorized under the
Plan shall be used for general corporate purposes.

     18.  Notice to Company of Disqualifying Disposition. By accepting an ISO
          ----------------------------------------------
granted under the Plan, each optionee agrees to notify the Company in writing,
immediately after such optionee makes a Disqualifying Disposition (as described
in Sections 421, 422 and 424 of the Code and regulations thereunder) of any
stock acquired pursuant to the exercise of ISOs granted under the Plan. A
Disqualifying Disposition is generally any disposition occurring on or before
the later of (a) the date two years following the date the ISO was granted or
(b) the date one year following the date the ISO was exercised.

     19.  Withholding of Additional Income Taxes. Upon the exercise of a
          --------------------------------------
Non-Qualified Option, the grant of an Award, the making of a Purchase of Common
Stock for less than its fair market value, the making of a Disqualifying
Disposition (as defined in paragraph 18), the vesting or transfer of restricted
stock or securities acquired on the exercise of an Option hereunder, or the
making of a distribution or other payment with respect to such stock or
securities, the Company may withhold taxes in respect of amounts that constitute
compensation includible in gross income. The Committee in its discretion may
condition (i) the exercise of an Option, (ii) the grant of any Award, (iii) the
making of a Purchase of Common Stock for less than its fair market value, or
(iv) the vesting or transferability of restricted stock or securities acquired
by exercising an Option, on the grantee's making satisfactory arrangement for
such withholding. Such arrangement may include payment by the grantee in cash or
by check of the amount of the withholding taxes or, to the extent (if any) of
minimum legal withholding requirements and at the discretion of the Committee,
by the grantee's delivery of previously held shares of Common Stock (provided
that any such shares of stock acquired through exercise of options or otherwise
as compensation from the Company shall have been held for at least six months)
or the withholding from the shares of Common Stock otherwise deliverable upon
exercise of an Option shares having an aggregate fair market value equal to the
amount of such withholding taxes.

     20.  Governmental Regulation. The Company's obligation to sell and deliver
          -----------------------
shares of the Common Stock under this Plan is subject to the approval of any

                  SERIES J PREFERRED STOCK PURCHASE AGREEMENT

     This Series J Preferred Stock Purchase Agreement (this "Agreement") is made
as of September 30, 1997 by and between Access Radiology Corporation, a Delaware
corporation (the "Company"), and each of the persons and entities listed on
Exhibit A (individually, an "Investor" and collectively, the "Investors").

     The parties agree as follows:

1.   Purchase And Sale Of Stock.

     1.1  Sale And Issuance Of Series J Preferred Stock.

          (a)  The Company will adopt and file with the Secretary of State of
the State of Delaware on or before the Initial Closing (as defined in Section
1.2(a)) an Amended and Restated Certificate of Incorporation in the form
attached hereto as Exhibit B (the "Restated Certificate").

          (b)  On the terms and subject to the conditions of this Agreement,
each Investor will purchase and the Company will sell and issue to each Investor
that number of shares of the Company's Series J Preferred Stock set forth
opposite each Investor's name on Exhibit A at a purchase price of $1.10 per
share. The Series J Preferred Stock will have the rights, preferences,
privileges and restrictions set forth in the Restated Certificate. The
obligations of the Investors under this Agreement are several and not joint.

     1.2  Closing.

          (a)  The purchase and sale of the Series J Preferred Stock, by the
Investors listed on Exhibit A as of the date hereof, will take place at the
offices of Cooley Godward LLP, One Maritime Plaza, 20th Floor, San Francisco,
California at 10:00 a.m. on the date hereof or at such other time and place as
the Company and Bedrock Capital Partners I, L.P. mutually agree, either orally
or in writing (which time and place are designated as the "Initial Closing"). In
addition, the purchase and sale of the Series J Preferred Stock by and to the
Additional Investors (as defined in Section 1.3) in accordance with Section 1.3
will take place at the offices of the Company or at such other places and at
such times as the Company and Additional Investors mutually agree, either orally
or in writing (together with the Initial Closing, each such time and place is
designated as a "Closing").

          (b)  At each Closing, the Company will deliver to each Investor a
certificate representing the shares of Series J Preferred Stock that such
Investor is purchasing at such

Closing against payment of the purchase price therefor by check, wire transfer
or as otherwise set forth on Exhibit A.

     1.3  Subsequent Sale of Series J Preferred Stock.

     If less than all of the authorized number of shares of Series J Preferred
Stock are sold at the Initial Closing, then, subject to the terms and conditions
of this Agreement, the Company may sell, on or before the 45th day after the
date hereof, up to the balance of the authorized but unissued Series J Preferred
Stock to such persons as the Board of Directors of the Company may determine at
the same price per share as the Series J Preferred Stock purchased and sold at
the Initial Closing. Any such sale shall be made upon the same terms and
conditions as those contained herein, and such persons or entities ("Additional
Investors") shall become parties to this Agreement and the Investors Rights
Agreement (as defined in Section 2.1), and will be an Investor for all purposes
hereunder and thereunder.

2.   REPRESENTATIONS AND WARRANTEES OF THE COMPANY.

     The Company hereby represents and warrants to each Investor that, except as
set forth on the schedule of exceptions attached as Exhibit C (the "Schedule of
Exceptions"):

     2.1  Organization; Good Standing; Qualification. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware, and is duly qualified and authorized to transact
business and is in good standing as a foreign corporation in each jurisdiction
in which the failure so to qualify would have a material adverse effect on the
business, properties or financial condition of the Company and its Subsidiaries
(as defined in Section 2.6) taken as a whole (a "Material Adverse Effect"). The
Company has no material assets or properties owned or leased by it situated in,
or employees or representatives authorized to bind it by contract resident in
jurisdictions other than Massachusetts, Georgia and Texas. The Company's sales
are made F.O.B. at the Company's principal offices in Massachusetts. Each of the
Subsidiaries is a corporation duly organized, validly existing and in good
standing under the laws of its state of incorporation, and is duly qualified and
authorized to transact business and is in good standing as a foreign corporation
in each jurisdiction in which the failure to so qualify would have a Material
Adverse Effect. Each of the Company and its Subsidiaries has all requisite
corporate power and authority to own and operate its properties and assets and
to carry on its business as now conducted and as presently proposed to be
conducted. The Company has all requisite corporate power and authority to
execute and deliver this Agreement and at each Closing will have all requisite
corporate power and authority to execute and deliver the Investors Rights
Agreement attached hereto as Exhibit D (the "Investors Rights Agreement"), to

Common Stock (as defined in Section 2.5) issuable upon conversion thereof and to
carry out the provisions of this Agreement, the Investors Rights Agreement and
the Restated Certificate.

<PAGE>

     2.2  Authorization. All corporate action on the part of the Company and its
officers, directors and stockholders necessary for the authorization, execution
and delivery of this Agreement and the Investors Rights Agreement, the
performance of all obligations of the Company hereunder and thereunder and the
authorization, issuance (or reservation for issuance), sale and delivery of the
Series J Preferred Stock being sold hereunder and the Common Stock issuable upon
conversion thereof has been taken or will be taken prior to the Initial Closing.
This Agreement and the Investors Rights Agreement, when executed and delivered,

applicable bankruptcy, reorganization, insolvency or other laws affecting
creditors' rights generally or by general principles of equity.

     2.3  Valid Issuance Of Preferred And Common Stock. The Series J Preferred

validly issued, fully paid and nonassessable and will be free of restrictions on
transfer other than restrictions on transfer under this Agreement and the
Investors Rights Agreement and under applicable state and federal securities
laws.

connection with the Company's execution, delivery or performance of this
Agreement or the Investors Rights Agreement, the offer, sale or issuance of the
Series J Preferred Stock by the Company or the issuance of Common Stock upon
conversion of the Series J Preferred Stock, except (a) the filing of the
Restated Certificate with the Secretary of State of the State of Delaware and
(b) such filings as have been made prior to the Initial Closing, except any
notices of sale required to be filed with the Securities and Exchange Commission
under Regulation D of the Securities Act of 1933, as amended (the "Securities
Act"), and such post-closing filings as may be required under applicable state
securities laws, all of which will be timely filed within the applicable periods
therefor.

     2.5  Capitalization And Voting Rights. The authorized capital of the
Company will consist immediately prior to the Initial Closing of:

          (a)  35,000,000 shares of common stock, par value $0.01 per share

     (d)  The outstanding shares of Common Stock and Preferred Stock have been

Securities Act and any relevant state securities laws or pursuant to valid

     (e)  Except for (1) the conversion privileges of the Preferred Stock, (2)
the rights provided in the Investors Rights Agreement and (3) currently
outstanding options to purchase 1,267,657 shares of Common Stock granted to
employees pursuant to the Company's 1994 Stock Plan (the "Option Plan") and
currently outstanding options to purchase 59,228 shares of Common Stock granted
to employees outside of the Option Plan, there are not outstanding any options,
warrants, rights (including conversion or preemptive rights and rights of first
refusal), proxy or stockholder agreements or agreements of any kind for the
purchase or acquisition from the Company of any of its securities. In addition
to the aforementioned options, the Company has reserved an additional 1,582,343
shares of its Common Stock for purchase upon exercise of options to be granted
in the future under the Option Plan. The Company is not a party or subject to
any agreement or understanding, and to the Company's knowledge there is no
agreement or understanding between any other persons, that affects or relates to
the voting or giving of written consents with respect to any security of the
Company or the voting by a director of the Company.

     2.6  Subsidiaries. Set forth in Section 2.6 of the Schedule of Exceptions
is a description of each corporation owned by the Company (collectively, the
"Subsidiaries") and the security ownership thereof. The Company does not own or
control, directly or indirectly, any interest in any other corporation,
partnership, limited liability company, association or other business entity.
The Company is not a participant in any joint venture, partnership or similar
arrangement. All of the outstanding equity securities (including securities or
instruments exercisable for or convertible into equity securities) of each of
the Subsidiaries are owned by the Company beneficially and of record and are not
subject to any mortgages, liens, claims or encumbrances. There are not
outstanding any options, warrants, rights (including conversion or preemptive
rights and rights of first refusal), proxy or stockholder agreements or
agreements of

                                      -4-
<PAGE>

any kind for the purchase or acquisition from the Company or any of the
Subsidiaries of any securities of any of the Subsidiaries.

     2.7  Contracts And Other Commitments. Neither the Company nor any of its
Subsidiaries has or is bound by any contract, agreement, lease or commitment,
written or oral, absolute or contingent, other than (a) contracts for the
purchase of supplies and services that were entered into in the ordinary course
of business, do not involve more than $50,000 and do not extend for more than
one year beyond the date hereof, (b) sales contracts entered into in the
ordinary course of business and (c) contracts terminable at will by the Company
on no more than 30 days' notice without cost or liability to the Company or one
of its Subsidiaries that are not material to the conduct of the business of the
Company and its Subsidiaries. For the purpose of this Section 2.7, employment
and consulting contracts, contracts with labor unions, license agreements and
any other agreements relating to the acquisition or disposition of Intangibles
(as defined in Section 2.18) other than standard end-user license agreements
will not be considered to be contracts entered into in the ordinary course of
business.

     2.8  Related Party Transactions. No employee, officer, consultant,
stockholder or director of the Company or any of its Subsidiaries or member of
his or her immediate family is indebted to the Company, nor is the Company or
any of its Subsidiaries indebted (or committed to make loans or extend or
guarantee credit) to any of them, other than for (a) payment of salary for
services rendered, (b) reimbursement for reasonable expenses incurred on behalf
of the Company or any of its Subsidiaries and (c) other standard employee
benefits made generally available to all employees (including stock option
agreements outstanding under the Option Plan). To the Company's knowledge
(without making an investigation as to persons who are not officers or
directors), none of such persons has any direct or indirect ownership interest
in any firm or corporation with which the Company or any of its Subsidiaries is
affiliated or with which the Company or any of its Subsidiaries has a business
relationship, or any firm or corporation that competes with the Company or any
of its Subsidiaries, except that employees, stockholders, consultants, officers
or directors of the Company or any of its Subsidiaries and members of their
immediate families may own stock in publicly traded companies that may compete
with the Company or any of its Subsidiaries. To the Company's knowledge, no
officer, director, consultant, employee or stockholder of the Company or any of
its Subsidiaries or any member of his or her immediate family is, directly or
indirectly, interested in any material contract with the Company or any of its
Subsidiaries (other than such contracts as relate to any such person's
employment with the Company or one of its Subsidiaries or ownership of capital
stock or other securities of the Company).

     2.9  Registration Rights. Except as provided in the Investors Rights
Agreement, the Company is presently not under any obligation and has not granted
any rights to register under the Securities Act any of its presently outstanding
securities or any of its securities that may subsequently be issued.

                                      -5-
<PAGE>

     2.10  Clearances, Approvals, Etc. The Company and its Subsidiaries have all
clearances, approvals, franchises, permits, licenses and any similar authority
including, without limitation, all approvals and clearances from the U.S. Food
and Drug Administration necessary for the conduct of their business as now being
conducted, and the Company believes they can obtain, without undue burden or
expense, any similar authority for the conduct of the business of the Company
and its Subsidiaries as presently proposed to be conducted. Neither the Company
nor any of its Subsidiaries is in default in any material respect under any of
such franchises, permits, licenses or other similar authority.

     2.11  Compliance With Other Instruments. Neither the Company nor any of its
Subsidiaries is in violation or default of (a) any provision of its certificate
of incorporation or bylaws, (b) any provision of any mortgage, indenture,
agreement, instrument or contract to which it is a party or by which it is bound
or (c) to the best of the Company's knowledge, any judgment, order, writ,
decree, statute, rule, regulation or restriction applicable to it including,
without limitation, the U.S. Federal Food, Drug and Cosmetic Act, as amended,
and regulations promulgated thereunder, which default or violation has had or
could reasonably be expected to have a Material Adverse Effect. The execution,
delivery and performance by the Company of this Agreement and the Investors
Rights Agreement and the consummation of the transactions contemplated hereby
and thereby will not result in any such violation or be in material conflict
with or constitute, with or without the passage of time or giving of notice,
either a material default under any such provision or an event that results in
the creation of any material lien, charge or encumbrance upon any assets of the
Company or any of its Subsidiaries or the suspension, revocation, impairment,
forfeiture or nonrenewal of any material franchise, permit, license or similar
authority applicable to the Company or any of its Subsidiaries, any of their
business or operations or any of their assets or properties.

     2.12  Litigation. There is no action, suit, proceeding or investigation
pending or, to the Company's knowledge, currently threatened against the Company
or any of its Subsidiaries that questions the validity of this Agreement or the
Investors Rights Agreement or the right of the Company to enter into such
agreements, or to consummate the transactions contemplated hereby or thereby, or
that might result, either individually or in the aggregate, in a Material
Adverse Effect or in any change in the current equity ownership of the Company.
Neither the Company nor any of its Subsidiaries is a party to or, to the best of
its knowledge, named in or subject to any order, writ, injunction, judgment or
decree of any court, government agency or instrumentality. There is no action,
suit, proceeding or investigation by the Company currently pending or that the
Company currently intends to initiate.

     2.13  Disclosure. The Company has provided each Investor with all
information reasonably available to it without undue expense that such Investor
has requested in writing for deciding whether to purchase the Series J Preferred
Stock. To the best of the Company's knowledge after reasonable investigation,
neither this Agreement nor the Investors Rights Agreement nor the other written
materials made or delivered in connection with the transactions contemplated
hereby, taken as a whole, contain any untrue statement of a material fact or
omit to

                                      -6-
<PAGE>

state a material fact necessary to make the statements herein or therein, in
light of the circumstances under which they were made or otherwise, not
misleading.

     2.14  Offering. Subject in part to the truth and accuracy of each
Investor's representations set forth in this Agreement, the offer, sale and
issuance of the Series J Preferred Stock as contemplated by this Agreement are
exempt from the registration requirements of the Securities Act, and neither the
Company nor any authorized agent acting on its behalf will take any action
hereafter that would cause the loss of such exemption.

     2.15  Title To Property And Assets; Leases. Except for (a) liens reflected
in the Financial Statements (as defined in Section 2.16), (b) liens for current
taxes not yet due or payable, (c) liens imposed by law and incurred in the
ordinary course of business for obligations not past due to carriers,
warehousemen, laborers, materialmen and the like, (d) liens in respect of
pledges or deposits under workers' compensation laws or similar legislation or
(e) minor defects in title, none of which, individually or in the aggregate,
materially interferes with the use of such property, the Company and its
Subsidiaries have good and marketable title to their property and assets free
and clear of all mortgages, liens, claims and encumbrances. With respect to the
property and assets they lease, the Company and its Subsidiaries are in
compliance with such leases and, to the best of the Company's knowledge, hold a
valid leasehold interest free of any mortgages, liens, claims or encumbrances,
subject to clauses (a)-(d) above.

     2.16  Financial Statements. The Company has delivered to each Investor its
audited consolidated financial statements (balance sheet and profit and loss
statement, statement of stockholders' equity and statement of cash flows
including notes thereto) at December 31, 1996 and for the fiscal years then
ended and its unaudited financial statements (balance sheet and profit and loss
statement and statement of cash flows) at June 30, 1997 and for the six months
then ended (the "Financial Statements"). The Financial Statements have been
prepared in accordance with generally accepted accounting principles applied on
a consistent basis throughout the periods indicated, except that the unaudited
Financial Statements omit notes thereto required by generally accepted
accounting principles. The Financial Statements fairly present the financial
condition and operating results of the Company and each of the Subsidiaries on a
consolidated basis as of the dates and for the periods indicated therein
(subject in the case of unaudited financial statements to normal year end
adjustments). Except as set forth in the Financial Statements, neither the
Company nor any of its Subsidiaries has any material liabilities, contingent or
otherwise, other than (a) liabilities incurred in the ordinary course of
business subsequent to June 30, 1997 and (b) obligations under contracts and
commitments incurred in the ordinary course of business and not required under
generally accepted accounting principles to be reflected in the Financial
Statements that in both cases, individually or in the aggregate, are not
material to the business, properties or financial condition of the Company and
its Subsidiaries, taken as a whole. Except as disclosed in the Financial
Statements, neither the Company nor any of its Subsidiaries is a guarantor or
indemnitor of any indebtedness of any other person or entity. Each of the
Company and its Subsidiaries maintains and will continue to

                                      -7-

maintain a standard system of accounting established and administered in
accordance with generally accepted accounting principles.

     2.17  Changes.  Since June 30, 1997 there has not been:

           (a)  any change in the assets, liabilities, financial condition or
operating results of the Company or any of its Subsidiaries from that reflected
in the Financial Statements, except changes in the ordinary course of business
that have not had a Material Adverse Effect;

           (b)  any damage, destruction or loss, whether or not covered by
insurance, that could reasonably be expected to have a Material Adverse Effect;

           (c)  any waiver or compromise by the Company or any of its
Subsidiaries of a valuable right or of a material debt owed to it;

           (d)  any satisfaction or discharge of any lien, claim or encumbrance

Effect;

           (e)  any material change to a material contract or arrangement by
which the Company or any of its Subsidiaries or any of their assets is bound or
subject;

           (f)  any material change in any compensation arrangement or agreement
with any employee, officer, consultant, director or stockholder of the Company
or any of its Subsidiaries;

           (g)  any sale, assignment or transfer of any material Intangibles of
the Company or any of its Subsidiaries;

order cancellation by, any major customer of the Company or any of its
Subsidiaries;

interest created by the Company or any of its Subsidiaries with respect to any
of its material properties or assets, except liens for taxes not yet due or
payable;

           (k)  any declaration, setting aside or payment of any dividend or
other distribution of the Company's assets in respect of any of the Company's
capital stock, or any direct or indirect redemption, purchase or other
acquisition of any of such stock by the Company;

                                      -8-
<PAGE>

           (l)  to the Company's knowledge, any other event or condition of any
character that could reasonably be expected to have a Material Adverse Effect;
or

           (m)  any agreement or commitment by the Company or any of its
Subsidiaries to do any of the things described in this Section 2.17.

     2.18  Intangibles. To the best of its knowledge, the Company and its
Subsidiaries own or possess sufficient legal rights to all patents, trademarks,
service marks, trade names, copyrights, trade secrets, licenses, information and
proprietary rights and processes (collectively, "Intangibles") necessary for
their business as now conducted and as proposed to be conducted without any
conflict with or infringement of the rights of others. Except for standard end-
user license agreements and licenses set forth in Section 2.18 of the Schedule
of Exceptions (the "Material Licenses"), there are no outstanding options,
licenses or agreements of any kind relating to the foregoing, nor is the Company
or any of its Subsidiaries bound by or a party to any options, licenses or
agreements of any kind with respect to the Intangibles of any other person or
entity. To the Company's knowledge, each Material License is valid and in full
force and effect, and is enforceable by the Company or one of its Subsidiaries
in accordance with its terms. To the Company's knowledge, no person or entity
has violated or breached, or declared or committed any default under, any
Material License. To the Company's knowledge, no event has occurred, and no
circumstance or condition exists, that might (with or without notice or lapse of
time) (a) result in a violation or breach of any of the provisions of any
Material License, (b) give any person or entity the right to declare a default
or exercise any remedy under any Material License, (c) give any person or entity
the right to accelerate the maturity or performance of any Material License or
(d) give any person or entity the right to cancel, terminate or modify any
Material License. Neither the Company nor any of its Subsidiaries has received
any communications alleging that the Company or any of its Subsidiaries has
violated or breached any provision of a Material License or misappropriated or
by conducting its business as proposed would misappropriate any of the
Intangibles of any other person or entity.

     2.19  Employees; Employee Compensation. To the best of the Company's
knowledge, there is no strike, labor dispute or union organization activities
pending or threatened between the Company or any of its Subsidiaries and any of
their employees. None of the employees of the Company or any of its Subsidiaries
belongs to any union or collective bargaining unit. To the best of the Company's
knowledge, the Company and its Subsidiaries have complied in all material
respects with all applicable state and federal equal opportunity and other laws
related to employment. To the best of the Company's knowledge, no employee of
the Company or any of its Subsidiaries is or will be in violation of any
judgment, decree or order, or any term of any employment contract, patent
disclosure agreement or other contract or agreement relating to the relationship
of any such employee with the Company or any of its Subsidiaries, or any other
party because of the nature of the business conducted or presently proposed to
be conducted by the Company or any of its Subsidiaries or to the use by the
employee of his or her best efforts with respect to such business. Neither the
execution nor delivery of this Agreement or the Investor Rights Agreement nor
the carrying on of the business of the Company and its

                                      -9-
<PAGE>

Subsidiaries by their employees nor the conduct of such business as proposed
will, to the Company's knowledge, conflict with or result in a breach of the
terms, conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any of such employees is now obligated.
Neither the Company nor any of its Subsidiaries is a party to or bound by any
currently effective employment contract, deferred compensation agreement, bonus
plan, incentive plan (other than the Option Plan), profit sharing plan,
retirement agreement or other employee compensation agreement. The Company is
not aware that any officer or key employee or consultant, or that any group of
key employees or consultants, of the Company or any of its Subsidiaries intends
to terminate their employment or service with the Company or any of its
Subsidiaries, nor does the Company or any of its Subsidiaries have a present
intention to terminate the employment or service of any of the foregoing.
Subject to general principles related to wrongful termination of employees, the
employment of each employee of the Company or any of its Subsidiaries is
terminable at the will of the employer.

     2.20  Tax Returns, Payments, And Elections. The Company and each of its
Subsidiaries have timely filed all tax returns and reports (federal, foreign,
state and local) as required by law. These returns and reports are true and
correct in all material respects. The Company and each of its Subsidiaries have
paid all takes and other assessments due, except those contested in good faith.
The provision for taxes as shown in the Financial Statements is adequate for
taxes due or accrued as of the dates thereof. Neither the Company nor any of its
Subsidiaries has elected pursuant to the Internal Revenue Code of 1986, as
amended (the "Code"), to be treated as an S corporation or a collapsible
corporation pursuant to Section 1362(a) or Section 341(f) of the Code, nor has
it made any other elections pursuant to the Code (other than elections that
relate solely to methods of accounting, depreciation, or amortization) that
would have a Material Adverse Effect. Neither the Company nor any of its
Subsidiaries has had any tax deficiency proposed or assessed against it or has
executed any waiver of any statute of limitations on the assessment or
collection of any tax or governmental charge. None of the income tax returns of
the Company or any of its Subsidiaries and none of their state income or
franchise tax or sales or use tax returns has ever been audited by governmental
authorities . Since the end of the Company's last fiscal year, the Company and
its Subsidiaries have made adequate provisions on its books of account for all
taxes, assessments and governmental charges with respect to their business,
properties and operations. The Company and its Subsidiaries have withheld or
collected from each payment made to each of its employees the amount of all
taxes including, but not limited to, federal income taxes, Federal Insurance
Contribution Act taxes and Federal Unemployment Tax Act taxes required to be
withheld or collected therefrom, and has paid the same to the proper tax
receiving officers or authorized depositaries.

     2.21  Insurance. The Company and its Subsidiaries have in full force and
effect fire and casualty insurance policies sufficient in amount (subject to
reasonable deductibles) to allow them to replace any properties that might be
damaged or destroyed, the loss of which, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect. The Company and its
Subsidiaries have in full force and effect products liability and errors and
omissions insurance in amounts customary for companies similarly situated.

                                      -10-
<PAGE>

     2.22  Environmental And Safety Laws. To the Company's knowledge, neither
the Company nor any of its Subsidiaries is in violation of any applicable
statute, law or regulation relating to the environment or occupational health
and safety, which violation has had or could reasonably be expected to have a
Material Adverse Effect. To the Company's knowledge, no material expenditures
are or will be required in order to comply with any such existing statute, law,
or regulation.

     2.23  Minute Books. The copy of the minute books of the Company provided to
Cooley Godward LLP contains minutes of all meetings of directors and
stockholders and all actions by written consent without a meeting by the
directors and stockholders since the date of incorporation and accurately
reflects all actions by the directors (and any committee of directors) and
stockholders with respect to all transactions referred to in such minutes in all
material respects.

3.   Representations And Warranties Of The Investors.

     Each Investor hereby represents and warrants to the Company that:

     3.1   Authorization. Such Investor has full power and authority to enter
into this Agreement and the Investors Rights Agreement, and this Agreement and
the Investors Rights Agreement, when executed and delivered, will constitute
valid and legally binding obligations of such Investor.

     3.2   Purchase Entirely For Own Account. The Series J Preferred Stock to be
purchased by such Investor and the Common Stock issuable upon conversion thereof
(collectively, the "Securities") will be acquired for investment for such
Investor's own account, not as a nominee or agent, and not with a view to the
resale or distribution of any part thereof, and that such Investor has no
present intention of selling, granting any participation in or otherwise
distributing the same. Such Investor does not have any contract, undertaking,
agreement or arrangement with any person or entity to sell, transfer or grant
participations to such person or to any third party with respect to any of the
Securities.

     3.3   Reliance Upon Investors' Representations. Such Investor understands
that the Series J Preferred Stock is not, and any Common Stock acquired on
conversion thereof at the time of issuance may not be, registered under the
Securities Act on the ground that the sale provided for in this Agreement and
the issuance of securities hereunder is exempt from registration under the
Securities Act pursuant to Section 4(2) thereof, and that the Company's reliance
on such exemption is predicated on the Investors' representations set forth
herein. Such Investor realizes that the basis for the exemption may not be
present if, notwithstanding such representations, the Investor has in mind
merely acquiring shares of the Series J Preferred Stock for a fixed or
determinable period in the future, or for a market rise, or for sale if the
market does not rise. Such Investor has no such intention.

                                      -11-
<PAGE>

     3.4   Receipt Of Information. Such Investor believes it has received all
the information such Investor considers necessary or appropriate for deciding
whether to purchase the Series J Preferred Stock. Such Investor has had an
opportunity to ask questions and receive answers from the Company regarding the
terms and conditions of the offering of the Series J Preferred Stock and the
business, properties, prospects and financial condition of the Company and to
obtain additional information (to the extent the Company possessed such
information or could acquire it without unreasonable effort or expense)
necessary to verify the accuracy of any information furnished to such Investor
or to which such Investor had access. The foregoing, however, does not limit or
modify the representations and warranties of the Company in Section 2 of this
Agreement or the right of the Investors to rely thereon.

     3.5   Investment Experience. Such Investor is experienced in evaluating and
investing in private placement transactions of securities of companies in a
similar stage of development and acknowledges that such Investor is able to fend
for itself, can bear the economic risk of such Investor's investment and has
such knowledge and experience in financial and business matters that such
Investor is capable of evaluating the merits and risks of the investment in the
Series J Preferred Stock. If other than an individual, such Investor has not
been organized for the purpose of acquiring the Series J Preferred Stock.

     3.6   Accredited Investor. Such Investor is an "accredited investor" as
defined in Rule 501 promulgated under the Securities Act.

     3.7   Restricted Securities. Such Investor understands that the Securities
may not be sold, transferred or otherwise disposed of without registration under
the Securities Act or an exemption therefrom, and that in the absence of an
effective registration statement covering the Securities or an available
exemption from registration under the Securities Act, the Securities must be
held indefinitely. In particular, such Investor is aware that the Securities may
not be sold pursuant to Rule 144 promulgated under the Securities Act unless all
of the conditions of that rule are met. Among the conditions for use of Rule 144
may be the availability of current information to the public about the Company.
Such information is not now available and the Company has no present plans to
make such information available.

<PAGE>

                                   Exhibit C

                            SCHEDULE OF EXCEPTIONS

     Capitalized terms used herein and not otherwise defined have the meanings
set forth in the Series J Preferred Stock Purchase Agreement, dated September
30, 1997, to which this Schedule of Exceptions is attached as Exhibit C.
Disclosure of any matter in any item of this Schedule is deemed to be disclosure
of such matter for purposes of all items with respect to which such matter is
required to be disclosed.  Disclosure of any matter in this Schedule does not,
by implication or otherwise, indicate that such matter is material.  Copies or
forms of all of the documents listed or described below have been provided to
Cooley Godward LLP and any summary below is qualified by reference to such
documents.

     2.5(c)  A list of the Company's shareholders has been provided to Cooley
Godward LLP.

     2.5(d)  The Company has issued a certificate for five shares of Series C
Preferred Stock to Joseph Tortorici, a holder who in fact subscribed and paid
for four shares. The Company is in the process of contacting Mr. Tortorici to
correct this error.

     2.5(e) The Company has outstanding warrants to purchase 255,482 shares of
Common Stock under various warrants issued in connection with private
placements of the Company's equity securities. The Company also has outstanding
an aggregate principal amount of $1,500,000 of Convertible Subordinated Notes
(the "Notes") that are expected to be converted into Series J Preferred Stock on
a dollar for dollar basis simultaneously with the Closing, and warrants to
purchase an additional 409,091 shares of Series J Preferred Stock at an exercise
price of $1.10 per share (the "Bridge Warrants"). The Bridge Warrants entitle
the holders of the Bridge Warrants, until June 30, 2002, to purchase from the
Company that amount of securities of the type issued in the Equity Financing
having an aggregate purchase price in the Equity Financing of $450,000. 10 for
an aggregate exercise price of $450,000.10.

     The Notes bear interest at the rate of 6% per annum, from the date of
issuance. If at any time prior to October 31, 1997, the Company completes an
Equity Financing (which for purposes of the Notes will be the sale of the
Company's Series J Preferred Stock pursuant to the Purchase Agreement), each
Note, effective on the closing of the Equity Financing, automatically converts
into the amount of securities that a purchaser in the Equity Financing would
receive upon payment of a purchase price equal to the outstanding principal and
accrued interest of such Note.

     Attached hereto as Exhibit C-1 are Post-Closing Capitalization Tables of
the Company which show the fully diluted Common Stock equivalent holdings of its
stockholders, assuming a $7,500,000 Series J Preferred Stock financing.

     2.8  Mr. Gary Sadow, a member of the Company's Medical and Technical
Advisory Board to whom stock options ha ve been granted, is an officer of
Sterling Diagnostic Imaging, Inc. ("Sterling"). The Company and Sterling have
entered into a letter of intent regarding the resale by Sterling of ACCESS
products. Mr. Sadow participated in the negotiation of definitive contractual
documentation.

     The Company was not in compliance with certain of the financial covenants
contained in the Fleet Loan documentation as of June 30, 1997. The Company has
obtained a written waiver from Fleet Bank. The Company expects that the
conditions giving rise to this non-compliance will be cured by the closing of
the financial contemplated by the Series J Preferred Stock Purchase Agreement
referenced above.

     2.12 The Company received a letter dated June 19, 1996 from counsel to
American Telemedicine International ("ATI"), written on behalf of ATI and
Massachusetts General Hospital ("MGH"). This letter states that ATI is
"associated . . . through merger" with RSTAR, Inc. ("RSTAR"), which is a former
employer of Howard Pinsky, an executive of the Company. The June 19th letter
asserts that U.S. Patent No. 5,469,353, issued to Mr. Pinsky and others and
assigned to the Company, is derived from proprietary information and trade
secrets of NIGH and RSTAR, has been improperly assigned and is currently
unenforceable due to incorrect ownership. The letter demands assignment of the
patent to ATI and the addition of a current ATI employee as an inventor. The
June 19th letter asserts that Mr. Pinsky had misappropriated proprietary
information and trade secrets relevant to the patent that were provided to him
while working for RSTAR. Counsel to ATI also made claims against Mr. Pinsky in a
separate letter addressed to Mr. Pinsky personally. The Company has agreed to
indemnify Mr. Pinsky against claims made against him in connection with this
dispute.

     The June 19th letter contained an offer to make documentation supporting
the claims of RSTAR and NIGH available to the Company.  In a responsive letter
dated July 3, 1996, patent counsel to the Company (Lahive & Cockfield) stated
that a preliminary investigation indicated that the assertions of the June 19th
letter were incorrect, and requested copies of the offered documentation.  In a
subsequent letter dated July 31, counsel to ATI stated that deliver of such
documentation would be conditioned on execution by the Company of an enclosed
"Confidential disclosure Agreement", the terms of which are unacceptable to the
Company.  The July 31 letter also requested that ATI receive documentation
relevant to the patent from the Company.  In a further response dated August 21,
counsel to the Company stated that the agreement proposed by ATI was not
acceptable, that in any event no confidentiality agreement should be required
for disclosure of material now included in an issued patent, and that the
Company was not prepared to deliver any material to ATI prior to receiving some
substantiation of ATI's claims.  The August 21 letter further stated the belief
of ACCESS that the claims of ATI and MGH are without merit.

     Subsequent to August 21, 1996, counsel to the Company and counsel to ATI
exchanged further letters and telephone calls regarding the terms on which ATI
would be willing to make

                                      -3-
<PAGE>

material supporting ATI's claims available to the Company. No resolution to this
matter was reached, and ATI and its counsel have not communicated with the
Company or its counsel since December 19, 1996, the date of the last letter that
counsel to the Company sent to counsel to ATI on this matter.

     The Company believes that the claims of ATI and NIGH are without merit and
intends to contest them vigorously.

     2.15    Fleet National Bank has a security interest in substantially all of
the Company's assets to secure loans outstanding under the Loan Agreement
referred to in Item 2.7.3.

     2.16    Reference is made to the matters disclosed in items 2.7 and 2.12.

     2.17(a) The Company issued $1,500,000 in principal amount of Convertible
Subordinated Notes, together with warrants to purchase 409,091 shares of Series
J Preferred Stock, in June 1997.

     The Company entered into a lease with Hartwell Group LLC for 25,404 square
feet in Lexington, Massachusetts on September 26, 1997.

     Reference is made to all other matters disclosed in response to Section
2.17.

     2.17(b) The Company is a party to a Vendor Program Agreement with DVI
Financial Services, Inc. ("DVI"), under which DVI had committed to provide
financing to qualified customers for the purchase of ACCESS products. The
Company has recently been informed that the business unit of DVI that provided
this financing has been discontinued, and that DVI is therefore no longer in a
position to continue the arrangements contemplated by the Vendor Program
Agreement. The Company does not plan to take any action with respect to this
matter.

     GE Medical Systems is a business unit of General Electric that succeeded
through an asset purchase to the business of Lockheed Martin Medical Imaging
("LMMIS") and the Purchase Agreement between the Company and LMMIS.  GE Medical
Systems has informed the Company that, as a matter of policy, GE Medical Systems
will not honor certain provisions of the LMMIS contract calling for rebates of
discounts granted by the Company if volume purchase targets are not met.  The
Company and GE Medical Systems are in the process of amending the LMMIS contract
to, among other things, eliminate these rebates.

     The Company has forgiven a loan of $10,000 to Dan Trott (Vice President of
Sales and Marketing).

     2.17(f) The Company has entered into employment contracts with Scott
Sheldon and Philip Holberton since June 30, 1997 (see item 2.7).

     2.18(h) Michael Schmertzler resigned as Chairman of the Board in July 1997.

     2.19    Reference is made to Item 2.7.

     2.20    The Company believes it is late in filing some of its state sales
tax returns. The Company does not believe that these filings will have a
Material Adverse Effect.
