ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The Company's Amended and Restated Certificate of Incorporation provides
that the Company shall, to the fullest extent permitted by Section 145 of the
DGCL, as amended from time to time, indemnify its officers and directors.
 
    Section 145 of the DGCL permits a corporation, under specified
circumstances, to indemnify its directors, officers, employees or agents against
expenses (including attorney's fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by them in connection with any
action, suit or proceeding brought by third parties by reason of the fact that
they were or are directors, officers, employees or agents of the corporation, if
such directors, officers, employees or agents acted in good faith and in a
manner they reasonably believed to be in or not opposed to the best interests of
the corporation and, with respect to any criminal action or proceeding, had no
reason to believe their conduct was unlawful. In a derivative action, i.e., one
by or in the right of the corporation, indemnification may be made only for
expenses actually and reasonably incurred by directors, officers, employees or
agents in connection with the defense or settlement of any action or suit, and
only with respect to a matter as to which they shall have acted in good faith
and in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation, except that no indemnification shall be made if
such person shall have been adjudged liable to the corporation, unless and only
to the extent that the court in which the action or suit was brought shall
determine upon application that the defendant directors, officers, employees or
agents are fairly and reasonably entitled to indemnity for such expenses despite
such adjudication of liability.
 
    The Company's Amended and Restated Certificate of Incorporation contains a
provision which eliminates, to the fullest extent permitted by the DGCL,
director liability for monetary damages for breaches of the fiduciary duty of
care or any other duty as a director.
 
    The Company intends to purchase a policy of director's and officer's
insurance that would in certain instances provide the funds necessary for the
Company to meet its indemnification obligations under its Amended and Restated
Certificate of Incorporation.

    Reference is hereby made to Section  of the Underwriting Agreement, the form
of which is filed as Exhibit 1.1 hereto, in which the Company has agreed to
indemnify the Underwriters and certain other persons against certain
liabilities.

made in reliance on the exemption from registration provided by Section 4(2) of
the Securities Act of 1933, as amended, as transactions by an issuer not
involving a public offering.

ITEM 17. UNDERTAKINGS
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company 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 and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Company of expenses
incurred or paid by a director, officer or controlling person of the Company 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 Company 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 and will be governed by the final
adjudication of such issue.
 
    The undersigned registrant hereby undertakes to provide to the
Representatives of the Underwriters at the closing specified in the underwriting
agreements certificates in such denominations and registered in such names as
required by the Representatives of the Underwriters to permit prompt delivery to
each purchaser.
 
    The undersigned registrant hereby undertakes that:
 
        (1) For purposes of determining any liability under the Securities Act
    of 1933, the information omitted from the form of prospectus filed as part
    of this Registration Statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4)
    or 497(h) under the Securities Act shall be deemed to be part of this
    Registration Statement as of the time it was declared effective.
 
        (2) For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective amendment that contains a form of
    prospectus 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.

         The purposes for which the Corporation is formed are to engage in any
lawful act or activity for which corporations may be organized under the General

                                   ARTICLE IV
                                  CAPITAL STOCK

         The total number of shares of all classes of stock which the
Corporation shall have authority to issue is 37,800,000 shares, consisting of
(a) 300,000 shares of Series A Cumulative Preferred Stock, $1.00 par value
("Series A Preferred"), (b) 5,000,000 shares of preferred stock, $1.00 par
value, which shares shall be issued from time to time in one or more series, at
the discretion of the Board of Directors (the "Undesignated Preferred Stock"),
(c) 30,000,000 shares of Common Stock, $.01 par value ("Common Stock"), and (d)
2,500,000 shares of Non-Voting Common Stock, $.01 par value (the "Non-Voting
Common Stock"). Cross references in each Subdivision A through D of this ARTICLE
IV refer to the Sections within such Subdivision unless otherwise indicated.

         The following is a statement of the designations, and the powers,
preferences and rights, and the qualifications, limitations or restrictions
thereof, in respect of each class of stock of the Corporation:

                  A. SERIES A CUMULATIVE PREFERRED STOCK

         1.       DIVIDENDS.

                  (a) The holders of shares of Series A Preferred shall be
entitled to receive dividends at the rate of $8.00 per share per annum, and no
more, payable when and as declared by the Board of Directors of the Corporation
and out of funds legally available for the payment thereof. Such dividends shall
be cumulative and shall accrue from the date of issue whether or not declared
and whether or not there are any funds of the Corporation legally available for
the payment of dividends. Accrued but unpaid dividends shall not bear interest.
The Board of Directors of the Corporation may fix a record date for the
determination of holders of Series A Preferred entitled to receive payment of a
dividend declared thereon, which record date shall be no more than 60 days prior
to the date fixed for the payment thereof.

                  (b) As long as any shares of Series A Preferred shall remain
outstanding, in no event shall any dividend be declared or paid upon, nor shall
any distribution be made upon, any Junior Capital Stock, other than a dividend
or distribution payable solely in shares of Common Stock of the Corporation, nor
shall any shares of Junior Capital Stock be purchased or redeemed by the
Corporation, nor shall any moneys be paid to or made available for a sinking
fund for the purchase or redemption of shares 

                                       2

<PAGE>

of any Junior Capital Stock, unless, in each such case, (i) full cumulative
dividends on the outstanding shares of Series A Preferred shall have been
declared and paid and (ii) any arrears or defaults in any mandatory redemption
of shares of Series A Preferred shall have been cured; PROVIDED, however, that
this Section l(b) shall not apply to any repurchase by the Corporation of shares
of its Common Stock pursuant to the terms of any employment agreement, stock
rights agreement, stock purchase plan, stock option plan or similar arrangement
between the Corporation and its employees. For purposes hereof, the term "Junior
Capital Stock" means any shares of capital stock of the Corporation, including
the Corporation's Common Stock and Non-Voting Common Stock, other than shares of
the Corporation's capital stock permitted to rank on a parity with or senior to
the Series A Preferred pursuant to Section 3 hereof.

         2.       LIQUIDATION, DISSOLUTION OR WINDING UP.

                  (a) In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of shares of Series A
Preferred then outstanding shall be entitled to be paid out of the assets of the
Corporation available for distribution to its stockholders, before any payment
shall be made to the holders of shares of any Junior Capital Stock by reason of
their ownership thereof, an amount equal to $100 per share of Series A
Preferred, as the case may be, plus all accrued but unpaid dividends thereon
(whether or not declared), and no more. If upon any such liquidation,
dissolution or winding up of the Corporation the remaining assets of the
Corporation available for distribution to its stockholders (after making all
distributions to which holders of capital stock ranking senior to the Series A
Preferred shall be entitled) shall be insufficient to pay the holders of shares
of Series A Preferred the full amount to which they shall be entitled pursuant
to this Section 2(a), the holders of shares of Series A Preferred, and any other
shares ranking on a parity therewith, shall share ratably in any distribution or
the remaining assets and funds of the Corporation in proportion to the
respective amounts which would otherwise be payable in respect of the shares of
Series A Preferred held by them upon such distribution if all amounts payable on
or with respect to such shares were paid in full.

                  (b) After the payment of all amounts required to be paid
pursuant to Section 2(a) to the holders of shares of Series A Preferred, and any
other shares ranking on a parity therewith, upon the dissolution, liquidation or
winding up of the corporation, the holders of shares of Junior Capital Stock
then outstanding shall share in any distribution of the remaining assets and
funds of the Corporation in the manner provided by law, in the Certificate of
Incorporation of the Corporation, as amended, or as provided in any pertinent
Certificate of Designation of the Corporation, as the case may be.

                  (c) Neither the merger or consolidation of the Corporation
into or with any other corporation, nor the sale of all or substantially all the
assets of the Corporation, shall be deemed to be a liquidation, dissolution or
winding up of the corporation for purposes of this Section 2 (unless in
connection therewith the liquidation of the corporation is specifically
approved).

                                       3
<PAGE>

         3. VOTING. Except as provided herein or by law, holders of Series A
Preferred shall not have any voting rights. So long as shares of the Series A
Preferred are outstanding, without the consent of the holders of at least the
majority of the Series A Preferred at the time outstanding given in person or by
proxy, either in writing or at a special meeting called for that purpose at
which the holders of the Series A Preferred shall vote separately as a class,
the Corporation may not (i) effect or validate the amendment, alteration or
repeal of any provision hereof which would adversely affect the dividend,
voting, redemption or liquidation rights of the Series A Preferred set forth
herein, or (ii) create or authorize any additional class or series of stock
ranking senior to or on a parity with the Series A Preferred as to dividends or
as to rights upon mandatory redemption, liquidation, dissolution or winding up;
increase the authorized number of shares of the Series A Preferred or of any
other class or series of capital stock of the Corporation ranking senior to or
on a parity with the Series A Preferred as to dividends or as to rights upon
mandatory redemption, liquidation, dissolution or winding up, whether any such
creation or authorization or increase shall be by means of amendment hereof,
merger, consolidation or otherwise; or issue additional shares of Series A
Preferred in excess of the number of shares authorized herein.

         4. OPTIONAL REDEMPTION. Shares of Series A Preferred may be redeemed in
whole or from time to time in part at any time (in amounts which shall aggregate
1,000 shares or any higher integral multiple of 1,000 shares), at the option of
the Corporation, at the redemption price of $100 per share plus all accrued but
unpaid dividends thereon (whether or not declared) as of the date fixed for
redemption (the "Redemption Price"). If the Corporation redeems less than all
outstanding shares of Series A Preferred, whether pursuant to this Section 4 or
Section 5 hereof, such redemption shall be made ratably among the holders of
Series A Preferred.

         5. MANDATORY REDEMPTION.

                  (a) On May 31, 2004, the Corporation shall redeem, at the
Redemption Price, all of the shares of Series A Preferred then outstanding.

                  (b) Subject to the prior rights of any holders of the
Corporation's indebtedness, upon the consummation of any underwritten public
offering of the Corporation's common stock registered pursuant to the Securities
Act of 1933, as amended, the Corporation shall apply any net cash proceeds of
such sale received by it to redeem, at the Redemption Price, shares of Series A
Preferred then outstanding.

                  (c) In the event of a consolidation or merger of the
Corporation with or into any other corporation (other than a merger in which the
Corporation is the surviving corporation and which will not result in more than
50% in voting power of the equity securities of the Corporation having general
voting power outstanding immediately after the effective date of such merger
being owned beneficially other than by persons who were the beneficial owners of
such equity securities immediately prior to such merger, in 

                                       4
<PAGE>

substantially the same proportions) (a "Change of Control"), or in the case of a
sale of all or substantially all of the assets of the Corporation as an entirety
to any other person (a "Sale of Assets"), the Corporation shall, at least 35
days prior to the effective date of any such change of Control or Sale of
Assets, give notice thereof to the holder or holders of Series A Preferred in
the manner described in Section 6(a) below. In the event that within 30 days
after the receipt of such notice, any holders of Series A Preferred elect, by
written notice to the Corporation, to have any or all of their Series A
Preferred redeemed, the Corporation shall redeem the same at the Redemption
Price not later than the day prior to the effective date of such Change of
Control or Sale of Assets.

         6. PROCEDURE FOR REDEMPTION.

                  (a) For purposes of this Section 6, the term "Redemption Date"
means any date on which the corporation elects or is required to redeem shares
of Series A Preferred pursuant to Sections 4 or 5. At least 20 days (and not
more than 60 days) prior to any Redemption Date (except in the case of a notice
given in connection with a Change of Control or Sale of Assets as provided in
Section 5(c) above, which notice shall be given at least 35 days prior to such
Change of Control or Sale of Assets), written notice (a "Redemption Notice")
shall be mailed, by first class or registered mail, postage prepaid, to each
holder of record of Series A Preferred, at his or its address last shown on the
records of the transfer agent of the Series A Preferred (or the records of the
corporation, if it serves as its own transfer agent), notifying such holder of
the Redemption Date, the Redemption Price, (except in the case of a redemption
pursuant to Section 5(c) above) the total number of shares to be redeemed and
the number of shares to be redeemed from such holder, and calling upon such
holder to surrender (in the case of a redemption pursuant to Section 5(c) above,
if such holder elects to have shares redeemed pursuant thereto) to the
Corporation, in the manner and at the place designated, his or its certificate
or certificates representing the shares to be redeemed. In order to facilitate
the redemption of the Series A Preferred, the Board of Directors may fix a
record date for the determination of holders of the Series A Preferred, not more
than 60 days nor less than 10 days prior to the Redemption Date.

                  (b) If the Redemption Notice is being sent by the Corporation
pursuant to Section 5(c) above, then, in addition to the information required to
be included in the Redemption Notice pursuant to Section 6(a) above, the
Redemption Notice shall also state:

                           (i) that the Redemption Notice is being sent pursuant
         to Section 5(c) hereof;

                           (ii) the parties to and the terms of the transaction
         or transactions resulting in the Change of Control or Sale of Assets;
         and

                           (iii) such other information as the Corporation in
         its sole discretion deems appropriate.

                                       5
<PAGE>

                  (c) On or prior to any Redemption Date, all holders of shares
of Series A Preferred whose shares are to be redeemed in whole or in part on
such date shall surrender their certificates representing such shares to the
Corporation, in the manner and at the place designated in the Redemption Notice,
and against such surrender the Redemption Price of such shares shall be paid to
the order of the person, whose name appears on each such certificate as the
owner thereof. Each surrendered certificate shall be canceled, provided that if
less than all the shares represented by any such certificate are redeemed, a new
certificate shall be issued representing the unredeemed shares. From and after
any Redemption Date, unless there shall have been a default in payment of the
Redemption Price, all rights of the holders of the shares of Series A Preferred
designated for redemption in the Redemption Notice (or otherwise designated by
the holders thereof for redemption pursuant to Section 5(c) above) as holders of
such shares of Series A Preferred (except the right to receive the Redemption
Price without interest against surrender of their certificate or certificates)
shall cease with respect to such shares, and such shares shall not thereafter be
transferred on the books of the Corporation or be deemed to be outstanding for
any purpose whatsoever.

                  (d) If the funds of the Corporation legally available for
redemption of Series A Preferred on any Redemption Date are insufficient to
redeem the full number of shares of Series A Preferred required by Section 5 to
be redeemed on such date, those funds which are legally available shall be used
to redeem the maximum possible number of such shares of Series A Preferred
ratably from each holder whose shares are otherwise required to be redeemed. At
any time thereafter when additional funds of the Corporation become legally
available for the redemption of Series A Preferred, such funds will be used, at
the end of the next succeeding fiscal quarter, to redeem the balance of the
shares which the Corporation was theretofore obligated to redeem, ratably on the
basis set forth in the preceding sentence.

         7. REACQUIRED SHARES. Any shares of Series A Preferred, which are
redeemed or otherwise acquired by the Corporation in any manner whatsoever shall
be retired and canceled promptly after the acquisition thereof and the number of
authorized shares of Series A Preferred shall be reduced accordingly.

                         B. UNDESIGNATED PREFERRED STOCK

         After the Series A Preferred has been redeemed in full, the
Undesignated Preferred Stock may be issued from time to time in one or more
series. The Board of Directors is authorized, after redemption in full of the
Series A Preferred, to provide for the issuance of shares of Undesignated
Preferred Stock in series and, by filing a certificate pursuant to the DGCL
(hereinafter referred to as a "Preferred Stock Designation"), to establish from
time to time the number of shares to be included in each such series, and to fix
the designation, powers, privileges, preferences and rights of the shares of
each such series and the qualifications, limitations and restrictions thereof.
The authority of the 

                                       6
<PAGE>

Board of Directors with respect to each series shall include, but not be limited
to, determination of the following:

                  (i) the designation of the series, which may be by
distinguishing number, letter or title;

                  (ii) the number of shares of the series, which number the
Board of Directors may thereafter (except where otherwise provided in the
Preferred Stock Designation) increase or decrease (but not below the number of
shares thereof then outstanding);

                  (iii) whether dividends, if any, shall be cumulative or
noncumulative, and, in the case of shares of any series having cumulative
dividend rights, the date or dates or method of determining the date or dates
from which dividends on the shares of such series shall be cumulative;

                  (iv) the rate of any dividends (or method of determining such
dividends) payable to the holders of the shares of such series, any conditions
upon which such dividends shall be paid and the date or dates or the method for
determining the date or dates upon which such dividends shall be payable;

                  (v) the price or prices (or method of determining such price
or prices) at which, the form of payment of such price or prices (which may be
cash, property or rights, including securities of the same or another
corporation or other entity) for which, the period or periods within which and
the terms and conditions upon which the shares of such series may be redeemed,
in whole or in part, at the option of the Corporation or at the option of the
holder or holders thereof or upon the happening of a specified event or events,
if any;

                  (vi) the obligation, if any, of the Corporation to purchase or
redeem shares of such series pursuant to a sinking fund or otherwise and the
price or prices at which, the form of payment of such price or prices (which may
be cash, property or rights, including securities of the same or another
corporation or other entity) for which, the period or periods within which and
the terms and conditions upon which the shares of such series shall be redeemed
or purchased, in whole or in part, pursuant to such obligation;

                  (vii) the amount payable out of the assets of the Corporation
to the holders of shares of the series in the event of any voluntary or
involuntary liquidation, dissolution or winding up of the affairs of the
Corporation;

                  (viii) provisions, if any, for the conversion or exchange of
the shares of such series, at any time or times at the option of the holder or
holders thereof or at the option of the Corporation or upon the happening of a
specified event or events, into shares of any other class or 

                                       7
<PAGE>

classes or any other series of the same or any other class or classes of stock,
or any other security, of the Corporation, or any other corporation or other
entity, and the price or prices or rate or rates of conversion or exchange and
any adjustments applicable thereto, and all other terms and conditions upon
which such conversion or exchange may be made;

                  (ix) restrictions on the issuance of shares of the same series
or of any other class or series, if any; and

                  (x) the voting rights, if any, of the holders of shares of the
series.

                                 C. COMMON STOCK

         1. DIVIDENDS. The holders of shares of Common Stock shall be entitled
to receive such dividends as from time to time may be declared by the Board of
Directors of the Corporation, subject to the provisions of the Series A
Preferred and to the provisions of the Preferred Stock Designation of any
Undesignated Preferred Stock.

         2. LIQUIDATION. In the event of any voluntary or involuntary
liquidation, dissolution or winding up of the Corporation, after payment shall
have been made to holders of Series A Preferred of the full amounts to which
they shall be entitled, the holders of Common Stock shall be entitled, to the
exclusion of the holders of Series A Preferred, to share ratably according to
the number of shares of Common Stock held by them in all remaining assets of the
Corporation available for distribution to its stockholders, subject to the
provisions of the Preferred Stock Designation of any Undesignated Preferred
Stock.

         3. VOTING. Each holder of Common Stock shall be entitled to one vote
per share.

                           D. NON-VOTING COMMON STOCK

         1. VOTING RIGHTS. The holders of shares of Non-Voting Common Stock
shall not be entitled to vote on any matter to be voted on by the stockholders
of the Corporation.

         2. DIVIDENDS. No payment of dividends or distributions shall be made to
the holders of shares of Non-Voting Common Stock unless and until the holders of
shares of preferred stock receive any preferential amounts to which they are
entitled under the provisions of the Series A Preferred or under the provisions
of the Preferred Stock Designation of any Undesignated Preferred Stock. Subject
to the limitation set forth in the preceding sentence of this Section 2, the
holders of shares of Non-Voting Common Stock shall be entitled to receive such
dividends and distributions as may be declared upon such shares of Non Voting
Common Stock, from time to time by a resolution or resolutions adopted by the
Board of Directors. Such dividends shall be equal in amount per share to
dividends declared on Common Stock; provided, however, that in the event that
the 

                                       8
<PAGE>

holders of Common Stock receive a dividend payable in shares of Common Stock or
other securities convertible into or exchangeable for shares of Common Stock,
then holders of Non-Voting Common Stock shall receive a number of shares of
Non-Voting Common Stock or of such other securities which is equal to the number
of shares of Non-Voting Common Stock or such other securities which they would,
but for this proviso, have received pursuant to this Section 2.

         3. LIQUIDATION. In the event of any voluntary or involuntary
liquidation, dissolution or winding up of the Corporation after payment or
provision for payment of the debts and liabilities of the Corporation and
payment to holders of Series A Preferred of the full amounts to which they shall
be entitled, all remaining assets of the Corporation shall be shared pro rata
among the holders of the Common Stock and the Non-Voting Common Stock available
for distribution to its stockholders, to the exclusion of the holders of the
Series A Preferred, based upon the number of shares held by them, subject to the
provisions of the Preferred Stock Designation of any undesignated Preferred.

         4. CONVERSION.

                  (a) RIGHT TO CONVERT. Subject to the terms and conditions of
this Section 4, the holder of any share or shares of Non-Voting Common Stock
shall have the right, at its option, at any time, to convert any such shares of
Non-Voting Common Stock (except that upon any liquidation, dissolution or
winding up of the Corporation the right of conversion shall terminate at 5:00
p.m. (New York City time) on the last business day preceding the date fixed for
payment of the amount distributable on Non-Voting Common Stock) into an equal
number of fully paid and nonassessable whole shares of Common Stock; provided,
however, that such conversion will not be permitted hereunder, and the
Corporation shall not be required to convert any shares of Non-Voting Common
Stock into Common Stock, to the extent that, at the date upon which such
conversion is deemed to take place as provided in Subsection 4(b) below, the
WCAS Group (as hereinafter defined) would, but for the limitation contained in
this proviso, hold, or otherwise have voting control over, in aggregate, more
than 49% of the voting securities of the Corporation outstanding at such time,
after taking into account the shares of Common Stock issuable upon such
conversion. Such rights of conversion shall be exercised by the holder thereof
by giving written notice to the Secretary of the Corporation that the holder
elects to convert a stated number of shares of Non-Voting Common Stock into
Common Stock and by surrender of a certificate or certificates for the shares so
to be converted to the Corporation at its principal office (or such other office
or agency of the Corporation as the Corporation may designate by notice in
writing to the holder or holders of Non-Voting Common Stock) at any time during
its usual business hours on the date set forth in such notice, together with a
statement of the name or names (with address) in which the certificate or
certificates for shares of Common Stock shall be issued.

                  (b) ISSUANCE OF CERTIFICATES; TIME CONVERSION EFFECTED.
Promptly after the receipt of the written notice referred to in Subsection 4(a)
and surrender of the certificate or certificates for the share or shares of
Non-Voting Common Stock eligible to 

                                       9
<PAGE>

be converted under Subsection 4(a), the Corporation shall issue and deliver, or
cause to be issued and delivered, to the holder, registered in such name or
names as such holder may direct, a certificate or certificates for the number of
whole shares of Common Stock issuable upon the conversion of such share or
shares of Non-Voting Common Stock. To the extent permitted by law, such
conversion shall be deemed to have been effected at 5:00 p.m. (New York City
time) on the date on which such written notice shall have been received by the
Corporation and the certificate or certificates for such share or shares shall
have been surrendered as aforesaid, and at such time the rights of the holder of
such share or shares of Non-Voting Common Stock shall cease, and the person or
persons in whose name or names any certificate or certificates for shares of
Common Stock shall be issuable upon such conversion shall be deemed to have
become the holder or holders of record of the shares represented thereby.

                  (c) FRACTIONAL SHARES; DIVIDENDS; PARTIAL CONVERSION.
Fractional shares may be issued upon conversion of Non-Voting Common Stock into
Common Stock. No payment or adjustment shall be made upon any conversion on
account of any cash dividends on the Common Stock issued upon such conversion.
At the time of each conversion, the Corporation shall pay in cash an amount
equal to all dividends accrued and unpaid on the shares surrendered for
conversion to the date upon which such conversion is deemed to take place as
provided in Subsection 4(b) above. In case the number of shares of Non-Voting
Common Stock represented by the certificate or certificates surrendered pursuant
to Subsection 4(a) exceeds the number of shares converted, the Corporation
shall, upon such conversion, execute and deliver to the holder thereof, at the
expense of the Corporation, a new certificate or certificates for the number of
shares of Non-Voting Common Stock represented by the certificate or certificates
surrendered which are not to be converted.

                  (d) SUBDIVISION OR COMBINATION OF STOCK. In case the
Corporation shall at any time subdivide its outstanding shares of Common Stock
into a greater number of shares, then the Non-Voting Common Stock shall be
proportionately subdivided, and conversely, in case the outstanding shares of
Common Stock shall be combined into a smaller number of shares, then the number
of shares of Non-Voting Common Stock immediately prior to such combination shall
be proportionately reduced. Upon any such event, the Corporation shall give
written notice thereof, by first class mail, postage prepaid, addressed to each
holder of shares of Non-Voting Common Stock at the address of such holder as
shown on the books of the Corporation.

                  (e) REORGANIZATION OR RECLASSIFICATION. If any capital
reorganization or reclassification of the capital stock of the Corporation or
any consolidation or merger of the Corporation with another corporation, or the
sale of all or substantially all its assets to another corporation, shall be
effected in such a way that holders of Common Stock shall be entitled to receive
stock, securities or assets with respect to or in exchange for Common Stock,
then, as a condition of such reorganization, reclassification, consolidation,
merger or sale, lawful and adequate provisions shall be made whereby each holder
of a share or shares of Non-Voting Common Stock shall thereafter have the right

                                       10
<PAGE>

to receive, upon the basis and upon the terms and conditions specified herein
and in lieu of the shares of Common Stock immediately theretofore receivable
upon the conversion of such share or shares of Non-Voting Common Stock, such
shares of stock, securities or assets as may be issued or payable with respect
to or in exchange for a number of outstanding shares of Common Stock equal to
the number of shares of such stock immediately theretofore so receivable had
such reorganization, reclassification, consolidation, merger or sale not taken
place, and in any such case appropriate provision shall be made with respect to
the rights and interests of such holder to the end that the provisions hereof
(including, without limitation, provisions for adjustments of the number of
shares of Common Stock issuable upon conversion of Non-Voting Common Stock)
shall thereafter be applicable, as nearly as may be, in relation to any shares
of stock, securities or assets thereafter deliverable upon such conversion. In
the event of a merger or consolidation of the Corporation as a result of which a
greater or lesser number of shares of common stock of the surviving corporation
are issuable to holders of Common Stock outstanding immediately prior to such
merger or consolidation, the number of shares of Common Stock issuable upon
conversion of Non-Voting Common Stock in effect immediately prior to such merger
or consolidation shall be adjusted in the same manner as though there were a
subdivision or combination of all outstanding shares of Common Stock. The
Corporation will not effect any such consolidation, merger or sale, unless prior
to the consummation thereof the successor corporation (if other than the
Corporation) resulting from such consolidation or merger or the corporation
purchasing such assets shall assume, by written instrument executed and mailed
or delivered to each holder of Non-Voting Common Stock at the last address of
such holder appearing on the books of the Corporation, the obligation to deliver
to such holder such shares of stock, securities or assets as, in accordance with
the foregoing provisions, such holder may be entitled to receive.

                  (f) NOTICE OF ADJUSTMENT. Upon any adjustment made pursuant to
Subsection 4(e), then and in each such case the Corporation shall give written
notice thereof, by first class mail, postage prepaid, addressed to each holder
of shares of Non-Voting Common Stock at the address of such holder as shown on
the books of the Corporation, which notice shall state the stock, securities or
assets issuable upon conversion of the Non-Voting Common Stock resulting from
such adjustment, setting forth in reasonable detail the method of calculation
and the facts upon which such calculation is based.

                  (g) OTHER NOTICES. In case at any time:

                           (i) the Corporation shall declare any dividend upon
         its Common Stock payable in cash or stock or make any other
         distribution to the holders of its Common Stock;

                           (ii) the Corporation shall offer for subscription pro
         rata to the holders of its Common Stock any additional shares of stock
         of any class or other rights;

                                       11
<PAGE>

                           (iii) there shall be any capital reorganization or
         reclassification of the capital stock of the Corporation, or a
         consolidation or merger of the Corporation with, or a sale of all or
         substantially all its assets to, another corporation; or

                           (iv) there shall be a voluntary or involuntary
         dissolution, liquidation or winding up of the Corporation,

then, in any one or more of said cases, the Corporation shall give, by first
class mail, postage prepaid, addressed to each holder of any shares of
Non-Voting Common Stock at the address of such holder as shown on the books of
the Corporation, (A) at least 20 days' prior written notice of the date on which
the books of the Corporation shall close or a record shall be taken for such
dividend, distribution or subscription rights or for determining rights to vote
in respect of any such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation or winding up, and (B) in the case of any such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding up, at least 20 days' prior written notice of the date
when the same shall take place. Such notice in accordance with the foregoing
clause (A) shall also specify, in the case of any such dividend, distribution or
subscription rights, the date on which the holders of Common Stock shall be
entitled thereto, and such notice in accordance with the foregoing clause (B)
shall also specify the date on which the holders of Common Stock shall be
entitled to exchange their Common Stock for securities or other property
deliverable upon such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation or winding up, as the case may be.

                  (h) STOCK TO BE RESERVED. The Corporation will at all times
reserve and keep available out of its authorized Common Stock or its treasury
shares, solely for the purpose of issue upon the conversion of the Non-Voting
Common Stock as herein provided such number of shares of Common Stock as shall
then be issuable upon the conversion of all outstanding shares of Non-Voting
Common Stock. The Corporation covenants that all shares of Common Stock which
shall be so issued shall be duly and validly issued and fully paid and
nonassessable and free from all taxes, liens and charges with respect to the
issue thereof. The Corporation will take all such action as may be necessary to
assure that all such shares of Common Stock may be so issued without violation
of any applicable law or regulation, or of any requirements of any national
securities exchange upon which the Common Stock of the Corporation may be
listed. The Corporation will not take any action which results in any adjustment
of the number of shares of Common Stock issuable upon conversion of the
Non-Voting Common Stock if the total number of shares of Common Stock issuable
after such action and upon conversion of the Non-Voting Common Stock would
exceed the total number of shares of Common Stock then authorized by the
Corporation's Certificate of Incorporation.

                                       12
<PAGE>

                  (i) NO REISSUANCE OF NON-VOTING COMMON STOCK. Shares of
Non-Voting Common Stock which are converted into shares of Common Stock as
provided herein shall not be reissued.

                  (j) ISSUE TAX. The issuance of certificates for shares of
Common Stock upon conversion of the Non-Voting Common Stock shall be made
without charge to the holders thereof for any issuance tax in respect thereof,
provided that the Corporation shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than that of the holder of the Non-Voting Common
Stock which is being converted.

                  (k) CLOSING OF BOOKS. The Corporation will at no time close
its transfer books against the transfer of any Non-Voting Common Stock or of any
shares of Common Stock issued or issuable upon the conversion of any shares of
Non-Voting Common Stock in any manner which interferes with the timely
conversion of such Non-Voting Common Stock.

                  (l) TRANSFER OF NON-VOTING COMMON STOCK. Any shares of
Non-Voting Common Stock that are transferred to any Person that is not included
within the WCAS Group shall immediately and automatically convert to Common
Stock, and all conditions of such conversion shall be in accordance with this
Section 4 of this Article IV.D.

                               STOCKHOLDER ACTION

                                       13
<PAGE>

         At any time prior to the date on which the Company's registration
statement on Form S-1 filed under the Securities Act of 1933, as amended, is
declared effective by the Securities and Exchange Commission (the "IPO Date") in
connection with an initial underwritten offering to the public of its capital
stock, any action required by law, this Certificate of Incorporation or the
Bylaws of the Company to be taken at a meeting of stockholders of the Company,
may be taken without a meeting pursuant to the terms and conditions of Section
228 of the DGCL. From and after the IPO Date, any action required by law, this
Amended and Restated Certificate of Incorporation or the Bylaws of the Company
to be taken at a meeting of stockholders of the Company, may be taken without a
meeting only if a consent in writing setting forth the action so taken shall be
signed by all stockholders entitled to vote on the action.

                                   ARTICLE VI
                               BOARD OF DIRECTORS

         6.1. POWERS OF THE BOARD OF DIRECTORS. The business and affairs of the
Corporation shall be managed by or under the direction of its Board of
Directors. In furtherance, and not in limitation, of the powers conferred by the
laws of the State of Delaware, the Board of Directors is expressly authorized
to:

                  (a) adopt, amend, alter, change or repeal the Bylaws of the
Corporation as provided in and subject to Article X of this Certificate of
Incorporation

                  (b) determine the rights, powers, duties, rules and procedures
that affect the power of the Board of Directors to manage and direct the
business and affairs of the Corporation, including the power to designate and
empower committees of the Board of Directors, to elect, appoint and empower the
officers and other agents of the Corporation, and to determine the time and
place of, and the notice requirements for, Board meetings, as well as quorum and
voting requirements for, and the manner of taking, Board action; and

                  (c) exercise all such powers and do all such acts as may be
exercised or done by the Corporation, subject to the provisions of the DGCL this
Certificate of Incorporation, and the Bylaws of the Corporation.

         6.2. NUMBER OF DIRECTORS. The number of directors of the Corporation
shall be not less than five (5) or more than twelve (12). The exact number of
directors shall be determined within such minimum and maximum by resolution
adopted by an affirmative vote of at least two-thirds (2/3) of the total number
of directors then in office.

         6.3. CLASSIFICATION, TERMS AND ELECTION OF DIRECTORS. The directors of
the Corporation shall be divided by the Board of Directors of the Corporation
into three classes, designated Class I, Class II and Class III. Each class shall
consist, as nearly as may be possible, of one-third of the total number of
directors constituting the entire Board of Directors. At the first annual
meeting of stockholders of the Corporation after the 

                                       14
<PAGE>

Corporation completes an initial underwritten offering to the public of capital
stock of the Corporation pursuant to a registration statement on Form S-1 filed
under the Securities Act of 1933, as amended (the "First Meeting"), the initial
term of the Class I directors will expire. At the first annual meeting of
stockholders of the Corporation after the First Meeting, the initial term of the
Class II directors will expire. At the second annual meeting of stockholders of
the Corporation after the First Meeting, the initial term of the Class III
directors will expire. At each annual meeting of stockholders of the
Corporation, successors to the class of directors whose term expires at that
annual meeting shall be elected or reelected for a three-year term. Except as
provided in Section 6.5, a director shall be elected by a plurality of the votes
cast by holders of shares of the class of stock represented at the annual
meeting of stockholders at which the director stands for election and entitled
to elect such director.

         If the number of directors is changed, any increase or decrease shall
be apportioned by the Board among the classes so as to maintain the number of
directors in each class as nearly equal as possible. In no case shall a decrease
in the number of directors have the effect of shortening the term of an
incumbent director.

         Each director shall serve until his or her successor is elected and
qualified or until his or her earlier resignation, retirement, disqualification,
removal from office or death.

         6.4 REMOVAL. The entire Board or any individual director may be removed
from office only for cause by the affirmative vote of the holders of at least a
majority of the outstanding shares of capital stock of the Corporation then
entitled to vote at an election of directors. Removal action may be taken at any
stockholders' meeting with respect to which notice of such purpose has been
given, and a removed director's successor may be elected at the same meeting to
serve the unexpired term.

         6.5 VACANCIES. A vacancy occurring on the Board, however occurring,
whether by increase in the number of directors, death, resignation, retirement,
disqualification, removal from office or otherwise, may be filled, until the
next stockholder election of the class for which the director shall have been
designated by the affirmative vote of at least two-thirds (2/3rds) of the total
number of directors then remaining in office, though they may constitute less
than a quorum of the Board.

         6.6 ELECTION OF DIRECTORS BY HOLDERS OF PREFERRED STOCK.
Notwithstanding any of the foregoing provisions in this Article VI, whenever the
holders of any one or more classes of preferred stock or series thereof issued
by the Corporation shall have the right, voting separately by class or series,
to elect directors at an annual or special meeting of stockholders, the number
of such directors, and the election, term of office, filling of vacancies and
other features of each such directorship, shall be governed by the terms of this
Certificate of Incorporation and any Preferred Stock Designation applicable
thereto, except that such directors so elected shall not be divided into classes
pursuant to this Article VI.

                                       15
<PAGE>

         6.7 AMENDMENT OR REPEAL. Notwithstanding any other provisions of this
Certificate of Incorporation or the Bylaws of the Corporation or any provision
of any law which might otherwise permit a lesser vote or no vote, but in
addition to any affirmative vote of the holders of any particular class or
series of capital stock of the Corporation required by law, this Certificate of
Incorporation or any Preferred Stock Designation, the provisions set forth in
this Article VI may not be repealed or amended in any respect unless such action
is approved by the affirmative vote of the holders of not less than two-thirds
(2/3rds) of the outstanding shares of the capital stock of the Corporation then
entitled to vote at an election of directors.

                                   ARTICLE VII
                    AMENDMENT OF CERTIFICATE OF INCORPORATION

         The Corporation reserves the right at any time and from time to time to
amend, alter, change or repeal any provisions contained in this Certificate of
Incorporation. Any such amendment, alteration, change or repeal shall require
the affirmative vote of both (a) a majority of the members of the Board then in
office and (b) a majority of the voting power of all of the outstanding shares
of capital stock of the Company then entitled to vote at an election of
directors. Notwithstanding anything contained in this Certificate of
Incorporation to the contrary, the affirmative vote of the holders of not less
than two-thirds (2/3rds) of all of the outstanding shares of capital stock of
the Company then entitled to vote at an election of directors shall be required
to alter, amend, adopt any provision inconsistent with or repeal Article V, VI,
VIII or this sentence.

                                  ARTICLE VIII
                                 INDEMNIFICATION

         8.1 RIGHT TO INDEMNIFICATION. Each person who was or is made a party or
is threatened to be made a party to or is otherwise involved in any action, suit
or proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact:

                  (a) that he or she is or was a director or officer of the
Corporation, or

                  (b) that he or she, being at the time a director or officer of
the Corporation, is or was serving at the request of the Corporation as a
director, trustee, officer, employee or agent of another corporation or of a
partnership, joint venture, trust or other enterprise, including service with
respect to an employee benefit plan (collectively, "another enterprise" or
"other enterprise"), whether either in case (a) or in case (b) the basis of such
proceeding is alleged action or inaction (x) in an official capacity as a
director or officer of the Corporation, or as a director, trustee, officer,
employee or agent of such other enterprise, or (y) in any other capacity related
to the Corporation or such other enterprise while so serving as a director,
trustee, officer, employee or agent, shall be indemnified and held harmless by
the Corporation to the fullest extent not prohibited by Section 145 of the DGCL
(or any successor provision or 

                                       16
<PAGE>

provisions) as the same exists or may hereafter be amended (but, in the case of
any such amendment, with respect to alleged action or inaction occurring prior
to such amendment, only to the extent that such amendment permits the
Corporation to provide broader indemnification rights than permitted prior
thereto), against all expense, liability and loss (including without limitation
attorneys' fees and expenses, judgments, fines, ERISA excise taxes or penalties
and amounts paid in settlement) reasonably incurred or suffered by such person
in connection therewith. The persons indemnified by this Article VIII are
hereinafter referred to as "indemnitees." Such indemnification as to such
alleged action or inaction shall continue as to an indemnitee who has after such
alleged action or inaction ceased to be a director or officer of the
Corporation, or director, officer, employee or agent of such other enterprise,
and shall inure to the benefit of the indemnitee's heirs, executors and
administrators. Notwithstanding the foregoing, except as may be provided in the
Bylaws of the Corporation or by the Board, the Corporation shall not indemnify
any such indemnitee in connection with a proceeding (or portion thereof)
initiated by such indemnitee (but this prohibition shall not apply to a
counterclaim, cross-claim or third-party claim brought by the indemnitee in any
proceeding) unless such proceeding (or portion thereof) was authorized by the
Board. The right to indemnification conferred in this Article VIII: (i) shall be
a contract right; (ii) shall not be affected adversely to any indemnitee by any
amendment of this Certificate of Incorporation with respect to any alleged
action or inaction occurring prior to such amendment; and (iii) shall, subject
to any requirements imposed by law and the Bylaws of the Corporation, include
the right to be paid by the Corporation the expenses incurred in defending any
such proceeding in advance of its final disposition.

         8.2 RELATIONSHIP TO OTHER RIGHTS AND PROVISIONS CONCERNING
INDEMNIFICATION. The rights to indemnification and to the advancement of
expenses conferred in this Article VIII shall not be exclusive of any other
right which any person may have or hereafter acquire under this Certificate of
Incorporation, or any statute, bylaw, agreement, vote of stockholders or
disinterested directors or otherwise. The Bylaws of the Corporation may contain
such other provisions concerning indemnification, including provisions
specifying reasonable procedures relating to and conditions to the receipt by
indemnitees of indemnification, provided that such provisions are not
inconsistent with the provisions of this Article VIII.

         8.3 AGENTS AND EMPLOYEES. The Corporation may, to the extent authorized
from time to time by the Board, grant rights to indemnification, and to the
advancement of expenses, to any employee or agent of the Corporation (or any
person serving at the Corporation's request as a director, trustee, officer,
employee or agent of another enterprise) or to any person who is or was a
director, officer, employee or agent of any of the Corporation's affiliates,
predecessor or subsidiary corporations or a constituent corporation absorbed by
the Corporation in a consolidation or merger or who is or was serving at the
request of such affiliate, predecessor or subsidiary corporation or of such
constituent corporation as a director, officer, employee or agent of another
enterprise, in each case as determined by the Board to the fullest extent of the
provisions of this Article VIII in cases of the indemnification and advancement
of expenses of directors 

                                       17
<PAGE>

and officers of the Corporation, or to any lesser extent (or greater extent, if
permitted by law) determined by the Board.

                                   ARTICLE IX
                                LIMITED LIABILITY

                  No person shall be personally liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
PROVIDED, HOWEVER, that the foregoing shall not eliminate or limit the liability
of a director (i) for any breach of the director's duty of loyalty to the
Corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the DGCL or (iv) for any transaction from which the director
derived an improper personal benefit. If the DGCL is subsequently amended to
further eliminate or limit the liability of a director, then a director of the
Corporation, in addition to the circumstances in which a director is not
personally liable as set forth in the preceding sentence, shall not be liable to
the fullest extent permitted by the amended DGCL. For purposes of this Article
IX, "fiduciary duty as a director" shall include any fiduciary duty arising out
of serving at the Corporation's request as a director of another corporation,
partnership, joint venture or other enterprise, and "personal liability to the
Corporation or its stockholders" shall include any liability to such other
corporation, partnership, joint venture, trust or other enterprise, and any
liability to the corporation in its capacity as a security holder, joint
venturer, partner, beneficiary, creditor or investor of or in any such other
corporation, partnership, joint venture, trust or other enterprise.

                                    ARTICLE X
                                     BYLAWS

         The Bylaws may be amended, altered, or changed or repealed and new
Bylaws may be adopted (1) at any annual or special meeting of stockholders by
the affirmative vote of the holders of a majority of the voting power of the
stock issued and outstanding and entitled to vote thereat, provided, however,
that any proposed amendment, alteration, change or repeal of, or the adoption of
any Bylaw by such vote of the stockholders that is inconsistent with, Sections
3, 4, 11 or 12 of Article II or Section 3 of Article III of the Bylaws shall
require the affirmative vote of the holders of not less than two-thirds (2/3rds)
of the voting power of all of the capital stock then outstanding, and provided,
further, however, that, in the case of any such stockholder action at a special
meeting of stockholders, notice of the proposed amendment, alteration, change,
repeal or adoption of the new Bylaw or Bylaws must be contained in the notice of
such special meeting, or (2) by the affirmative vote of a majority of the Board
of Directors; PROVIDED, HOWEVER, that the stockholders entitled to vote may
prescribe that any Bylaw adopted by the stockholders may not be amended,
altered, changed or repealed by the Board of Directors; and PROVIDED, FURTHER,
that no Bylaws hereafter adopted shall invalidate any prior act of the directors
that would have been valid if such new Bylaws had not been adopted.

                          ACCREDO HEALTH, INCORPORATED
                            (a Delaware corporation)

                                    ---------

                                    ARTICLE I


                                     OFFICES

         The registered office of the Corporation in the State of Delaware shall
be located in the City of Wilmington, County of New Castle. The Corporation may
establish or discontinue, from time to time, such other offices within or
without the State of Delaware as may be deemed proper for the conduct of the
Corporation's business.


                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

         SECTION 1. PLACE OF MEETINGS. All meetings of stockholders shall be
held at such place or places, within or without the State of Delaware, as may
from time to time be fixed by the Board of Directors, or as shall be specified
in the respective notices, or waivers of notice, thereof.

         SECTION 2. ANNUAL MEETING. The annual meeting of stockholders for the
election of Directors and the transaction of other business shall be held on
such date and at such place as may be designated by the Board of Directors. At
each annual meeting the stockholders entitled to vote shall elect a Board of
Directors and may transact such other proper business as may come before the
meeting.

         SECTION 3. SPECIAL MEETINGS. A special meeting of the stockholders, or
of any class thereof entitled to vote, for any purpose or purposes, may be
called at any time by the Chairman of the Board, if any, or the Chief Executive
Officer or by order of the Board of Directors and shall be called by the
Secretary upon the written request of stockholders holding of record not less
than two-thirds of the outstanding shares of stock of the Corporation entitled
to vote at such meeting. Such written request shall state the purpose or
purposes for which such meeting is to be called. The only business which may be
conducted at such a meeting, other than procedural matters and matters relating
to the conduct of the meeting, shall be the matter or matters described in the
notice of the meeting.


<PAGE>

         SECTION 4. NOTICE OF MEETINGS. Except as otherwise provided by law,
written notice of each meeting of stockholders, whether annual or special,
stating the place, date and hour of the meeting shall be given not less than ten
days or more than sixty days before the date on which the meeting is to be held
to each stockholder of record entitled to vote thereat by delivering a notice
thereof to him personally or by mailing such notice in a postage prepaid
envelope directed to him at his address as it appears on the records of the
Corporation, unless he shall have filed with the Secretary of the Corporation a
written request that notices intended for him be directed to another address, in
which case such notice shall be directed to him at the address designated in
such request. Notice shall not be required to be given to any stockholder who
shall waive such notice in writing, whether prior to or after such meeting, or
who shall attend such meeting in person or by proxy unless such attendance is
for the express purpose of objecting, at the beginning of such meeting, to the
transactions of any business because the meeting is not lawfully called or
convened. Every notice of a special meeting of the stockholders, besides the
time and place of the meeting, shall state briefly the objects or purposes
thereof.

         SECTION 5. LIST OF STOCKHOLDERS. It shall be the duty of the Secretary
or other officer of the Corporation who shall have charge of the stock ledger to
prepare and make, at least ten days before every meeting of the stockholders, a
complete list of the stockholders entitled to vote thereat, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in his name. Such list shall be open to the examination of
any stockholder, for any purpose germane to the meeting, during ordinary
business hours, for a period of at least ten days prior to the meeting, either
at a place within the city where the meeting is to be held, which place shall be
specified in the notice of the meeting, or, if not so specified, at the place
where the meeting is to be held. The list shall be kept and produced at the time
and place of the meeting during the whole time thereof and subject to the
inspection of any stockholder who may be present. The original or duplicate
ledger shall be the only evidence as to who are the stockholders entitled to
examine such list or the books of the Corporation or to vote in person or by
proxy at such meeting.

         SECTION 6. QUORUM. At each meeting of the stockholders, the holders of
record of a majority of the issued and outstanding stock of the Corporation
entitled to vote at such meeting, present in person or by proxy, shall
constitute a quorum for the transaction of business, except where otherwise
provided by law, the Certificate of Incorporation or these By-laws. In the
absence of a quorum, any officer entitled to preside at, or act as Secretary of,
such meeting shall have the power to adjourn the meeting from time to time until
a quorum shall be constituted.

         SECTION 7.  ORGANIZATION AND PROCEDURE.

         (a) The Chairman of the Board, or, in the absence of the Chairman of
the Board, the Vice Chairman of the Board, or any other person designated by the
Board of Directors, shall preside at meetings of stockholders. The Secretary of
the Corporation 


                                      -2-
<PAGE>

shall act as secretary, but in the absence of the Secretary, the presiding
officer may appoint a secretary.

         (b) At each meeting of stockholders, the chairman of the meeting shall
fix and announce the date and time of the opening and the closing of the polls
for each matter upon which the stockholders will vote at the meeting and shall
determine the order of business and all other matters of procedure. Except to
the extent inconsistent with any such rules and regulations as adopted by the
Board of Directors, the chairman of the meeting may establish rules, which need
not be in writing, to maintain order for the conduct of the meeting, including,
without limitation, restricting attendance to bona fide stockholders of record
and their proxies and other persons in attendance at the invitation of the
chairman and making rules governing speeches and debates. Except to the extent
inconsistent with any rules and regulations adopted by the Board of Directors,
the chairman of the meeting acts in his or her absolute discretion and his or
her rulings are not subject to appeal.

         SECTION 8. VOTING. Every stockholder of record who is entitled to vote
shall at every meeting of the stockholders be entitled to one vote for each
share of stock held by him on the record date. At all meetings of the
stockholders, a quorum being present, all matters shall be decided by majority
vote of the shares of stock entitled to vote held by stockholders present in
person or by proxy, except as otherwise required by law or the Certificate of
Incorporation. Unless demanded by a stockholder of the Corporation present in
person or by proxy at any meeting of the stockholders and entitled to vote
thereat or so directed by the chairman of the meeting or required by law, the
vote thereat on any question need not be by written ballot. On a vote by written
ballot, each ballot shall be signed by the stockholder voting, or in his name by
his proxy, if there be such proxy, and shall state the number of shares voted by
him and the number of votes to which each share is entitled.

         SECTION 9. PROXIES. Each stockholder entitled to vote at a meeting of
stockholders or to express consent to corporate action in writing without a
meeting may authorize another person or persons to act for him by proxy. A proxy
acting for any stockholder shall be duly appointed by an instrument in writing
subscribed by such stockholder. No proxy shall be valid after the expiration of
three years from the date thereof unless the proxy provides for a longer period.

         SECTION 10. INSPECTORS. The Board of Directors by resolution shall, in
advance of any meeting of stockholders, appoint one or more inspectors, which
inspector or inspectors may include individuals who serve the Corporation in
other capacities, including, without limitation, as officers, employees, agents
or representatives of the Corporation, to act at the meeting and make a written
report thereof. One or more persons may be designated by the Board of Directors
as alternate inspectors to replace any inspector who fails to act. If no
inspector or alternate is able to act at a meeting of stockholders, the chairman
of the meeting shall appoint one or more inspectors to act at the meeting. Each
inspector, before discharging his or her duties, shall take and sign an 


                                      -3-
<PAGE>

oath faithfully to execute the duties of inspector with strict impartiality and
according to the best of his or her ability. The inspector(s) shall have the
duties prescribed by the Delaware General Corporation Law.

         SECTION 11. NOMINATIONS OF DIRECTORS. Nominations of candidates for
election as directors at any annual or special meeting of stockholders may be
made (i) by, or at the direction of, a majority of the Board of Directors or
(ii) by any stockholder of record entitled to vote at such meeting. Except to
the extent otherwise required by law, only persons nominated in accordance with
procedures set forth in this Section 11 shall be eligible for election as a
director at an annual or special meeting.

         Nominations, other than those made by, or at the direction of, a
majority of the Board of Directors, shall be made pursuant to timely notice in
writing to the Secretary of the Corporation as set forth in this Section 11. To
be timely, a stockholder's notice shall be delivered to, or mailed and received
at, the principal executive offices of the Corporation not less than sixty (60)
days nor more than ninety (90) days prior to the date of the scheduled annual or
special meeting, regardless of postponements, deferrals, or adjournments of that
meeting to a later date; provided, however, that if less than seventy (70) days'
notice or prior public disclosure of the date of the scheduled annual or special
meeting is given or made, notice by the stockholder to be timely must be so
delivered or received no later than the close of business on the tenth (10th)
day following the earlier of the day on which such notice of the date of the
scheduled annual or special meeting was mailed or the day on which such public
disclosure was made. Such stockholder's notice shall be set forth (i) as to each
person whom the stockholder proposes to nominate 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's equity securities which are Beneficially Owned (as defined
below) by such person on the date of such stockholder notice and (d) and any
other information relating to such person that would be required to be disclosed
pursuant to Regulation 13D under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), in connection with the acquisition of shares, and pursuant
to Regulation 14A under the Exchange Act, in connection with the solicitation of
proxies with respect to nominees for election as directors, regardless of
whether such person is subject to the provisions of such regulations, including,
but not limited to, information required to be disclosed by Items 4(b) and 6 of
Schedule A of Regulation 14A and information which would be required to be filed
on Schedule B of Regulation 14A with the Securities and Exchange Commission (as
such Items and Schedules are in effect on the date hereof and such additional
information as may be required by those provisions or successor provisions
adopted after the date thereof); and (ii) as to the stockholder giving the
notice (a) the name and address, as they appear on the Corporation's books, of
such stockholder and any other stockholder who is a record or Beneficial Owner
of any equity securities of the Corporation and who is known by such stockholder
to be supporting such nominee(s) and (b) the class and number of shares of the
Corporation's equity securities which are Beneficially Owned and owned of record
by such stockholder on the date of such stockholder notice and the number of
shares of the Corporation's equity securities 


                                      -4-
<PAGE>

Beneficially Owned and owned of record by any Person known by such stockholder
to be supporting such nominee(s) on the date of such stockholder notice. At the
request of a majority of the Board of Directors any person nominated by, or at
the direction of, the Board of Directors for election as a director at an annual
or special meeting shall furnish to the Secretary of the Corporation that
information required to be set forth in a stockholder's notice of nomination
which pertains to the nominee. Ballots bearing the names of all the persons who
have been nominated for election as directors at an annual or special meeting in
accordance with procedures set forth in this Section 11 shall be provided for
use at the annual meeting.

         A majority of the directors may reject any nomination by a stockholder
not timely made in accordance with the requirements of this Section 11. If a
majority of the directors determines that the information provided in a
stockholder's notice does not satisfy the informational requirements of this
Section 11 in any material respect, the Secretary of the Corporation shall
promptly notify such stockholder of the deficiency in the notice. The
stockholder shall have an opportunity to cure the deficiency by providing
additional information to the Secretary within such period of time, not to
exceed five (5) days, from the date such deficiency notice is given to the
stockholder, as a majority of the directors shall reasonably determine. If the
deficiency is not cured within such period, or if a majority of the directors
reasonably determine that the additional information provided by the
stockholder, together with the information previously provided, does not satisfy
the requirements of this Section 11 in any material respect, then a majority of
the directors may reject such stockholder's nomination. The Secretary of the
Corporation shall notify a stockholder in writing whether his nomination has
been made in accordance with the time and informational requirements of this
Section 11. Notwithstanding the procedure set forth in this Section 11, if the
majority of the directors does not make a determination as to the validity of
any nominations by a stockholder, the presiding officer of the annual or special
meeting shall determine and declare at the annual or special meeting whether a
nomination was not made in accordance with the terms of this Section 11. If the
presiding officer determines that a nomination was not made in accordance with
the terms of this Section 11, he shall so declare at the annual or special
meeting and the defective nomination shall be disregarded.

         For the purposes of this Section 11 and Section 12, a person shall be
considered the "Beneficial Owner" of any security (whether or not owned of
record):

         (a) with respect to which such person or any affiliate or associate (as
those term are defined under Rule 12b-2 of the General Rules and Regulations
under the Exchange Act) of such person directly or indirectly has or shares (i)
voting power, including the power to vote or to direct the voting of such
securities and/or (ii) investment power, including the power to dispose of or to
direct the disposition of such security;

         (b) which such person or any affiliate or associate of such person has
(i) the right or obligation to acquire (whether such right or obligation is
exercisable immediately or only after the passage of time) pursuant to any
agreement, arrangement or 


                                      -5-
<PAGE>

understanding (whether or not in writing) or upon the exercise of conversion
rights, exchange rights, warrants or options, or otherwise, and/or (ii) the
right to vote pursuant to any agreement, arrangement or understanding (whether
or not in writing and whether or not such right is exercisable immediately or
only after the passage of time); or

         (c) which is Beneficially Owned within the meaning of (a) or (b) of
this paragraph by any other person with which such first-mentioned person or any
of its affiliates or associates has any agreement, arrangement or understanding
(whether or not in writing), with respect to (x) acquiring, holding, voting or
disposing of such security or any security convertible into or exchangeable or
exercisable for such security, or (y) acquiring, holding or disposing of all or
substantially all of the assets or businesses of the Corporation or a subsidiary
of the Corporation.

         SECTION 12. NEW BUSINESS. At an annual or special meeting of
stockholders, only such new business shall be conducted, and only such proposals
shall be acted upon, as shall have been brought before the annual or special
meeting (a) by, or at the direction of, the majority of the Board of Directors
or (b) by any stockholder of the Corporation who complies with the notice
procedures set forth in this Section 12, except to the extent otherwise
requested by law. For the proposal to be properly brought before an annual or
special meeting by a stockholder, the stockholder must have given timely notice
thereof in writing to the Secretary of the Corporation. To be timely, a
stockholder's notice must be delivered to, or mailed and received at, the
principal executive offices of the Corporation not less than sixty (60) days nor
more than ninety (90) days prior to the scheduled annual or special meeting,
regardless of any postponement, deferrals or adjournments of that meeting to a
later date, provided, however, that if less than seventy (70) days' notice or
prior public disclosure of the date of the scheduled annual or special meeting
is given or made, notice by the stockholder, to be timely, must be so delivered
or received not later than the close of business on the tenth (10th) day
following the earlier of the day on which such notice of the date of the
scheduled annual or special meeting was mailed or the day on which such public
disclosure was made. A stockholder's notice to the Secretary shall set forth as
to each matter the stockholder proposes to bring before the annual or special
meeting (a) a brief description of the proposal desired to be brought before the
annual or special meeting and the reasons for conducting such business at the
annual or special meeting, (b) the name and address, as they appear on the
Corporation's books, of the stockholder proposing such business and any other
stockholder who is the record or Beneficial Owner of any equity security of the
Corporation known by such stockholder to be supporting such proposal, (c) the
class and number of shares of the Corporation's equity securities which are
Beneficially Owned and owned of record by the stockholder giving the notice on
the date of such stockholder notice and by, any other record or Beneficial
Owners of the Corporation's equity securities known by such stockholder to be
supporting such proposal on the date of such stockholder notice, and (d) any
financial or other interest of the stockholder in such proposal.

         A majority of the directors may reject any stockholder proposal not
timely made in accordance with the terms of this Section 12. If a majority of
the directors determine

that the information provided in a stockholder's notice does not satisfy the
informational requirements of this Section 12 in any material respect, the
Secretary of the Corporation shall promptly notify such stockholder of the

determine. If the deficiency is not cured within such period, or if the majority

the Certificate of Incorporation or these Bylaws, any action required or

                                 INDEMNIFICATION

         SECTION 1. INDEMNIFICATION PROVISIONS IN CERTIFICATE OF INCORPORATION.
The provisions of this Section VI are intended to supplement Article VIII of the
Certificate of Incorporation pursuant to Sections 8.2 and 8.3 thereof. To the
extent that this Section VII contains any provisions inconsistent with said
Article VIII, the provisions of the Certificate of Incorporation shall govern.
Terms defined in such Article VIII shall have the same meaning in this Section
VI.

         SECTION 2. INDEMNIFICATION OF EMPLOYEES. The Corporation may by
resolution of its Board of Directors indemnify and advance expenses to its
employees to the same extent as to its directors and officers, as set forth in
the Certificate of Incorporation and in this Section VI of the Bylaws of the
Corporation.

         SECTION 3. UNDERTAKINGS FOR ADVANCES OF EXPENSES. If and to the extent
the Delaware General Corporation Law requires, an advancement by the Corporation
of expenses incurred by an indemnitee pursuant to clause (iii) of the last
sentence of Section 8.1 of the Certificate of Incorporation (hereinafter an
"advancement of expenses") shall be made only upon delivery to the Corporation
of an undertaking (hereinafter an "undertaking"), by or on behalf of such
indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is no further right to
appeal (hereinafter a "final adjudication") that such indemnitee is not entitled
to be indemnified for such expenses under Article VIII of the Certificate of
Incorporation or otherwise.

         SECTION 4. CLAIMS FOR INDEMNIFICATION. If a claim for indemnification
under Section 8.1 of the Certificate of Incorporation is not paid in full by the
Corporation within 60 days after it has been received in writing by the
Corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be 20 days, the indemnitee may at any
time thereafter bring suit against the Corporation to recover the unpaid amount
of the claim. If successful in whole or in part in any such suit, or in a suit
brought by the Corporation to recover an advancement of expenses pursuant to the
terms of an undertaking, the indemnitee shall be entitled to be paid also the
expense 


                                      -13-
<PAGE>

of prosecuting or defending such suit. In any suit brought by the indemnitee to
enforce a right to indemnification hereunder (but not in a suit brought by the
indemnitee to enforce a right to an advancement of expenses) it shall be a
defense that, and in any suit by the Corporation to recover an advancement of
expenses pursuant to the terms of an undertaking the Corporation shall be
entitled to recover such expenses only upon a final adjudication that, the
indemnitee has not met the applicable standard of conduct set forth in Section
145 of the Delaware General Corporation Law (or any successor provision or
provisions). Neither the failure of the Corporation (including the Board of
Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such suit that indemnification of the
indemnitee is proper in the circumstances because the indemnitee has met the
applicable standard of conduct set forth in Section 145 of the Delaware General
Corporation Law (or any successor provision or provisions), nor an actual
determination by the Corporation (including the Board of Directors, independent
legal counsel, or its stockholders) that the indemnitee has not met such
applicable standard of conduct, shall create a presumption that the indemnitee
has not met the applicable standard of conduct or, in the case of such a suit
brought by the indemnitee, be a defense to such suit. In any suit brought by the
indemnitee to enforce a right to indemnification or to an advancement of
expenses hereunder, or by the Corporation to recover an advancement of expenses
pursuant to the terms of an undertaking, the burden of proving that the
indemnitee is not entitled to be indemnified, or to have or retain such
advancement of expenses, under Article VIII of the Certificate of Incorporation
or this Section VI or otherwise, shall be on the Corporation.

         SECTION 5. INSURANCE. The Corporation may maintain insurance, at its
expense, to protect itself and any director, trustee, officer, employee or agent
of the Corporation or another enterprise against any expense, liability or loss,
whether or not the Corporation would have the power to indemnify such person
against such expense, liability or loss under the Delaware General Corporation
Law.

         SECTION 6. SEVERABILITY. In the event that any of the provisions of
this Section VI (including any provision within a single section, paragraph or
sentence) is held by a court of competent jurisdiction to be invalid, void or
otherwise unenforceable, the remaining provisions are severable and shall remain
enforceable to the fullest extent permitted by law.

                                   ARTICLE VII
                            SHARES AND THEIR TRANSFER

         SECTION 1. CERTIFICATE FOR STOCK. Every stockholder of the Corporation
shall be entitled to a certificate or certificates, to be in such form as the
Board of Directors shall prescribe, certifying the number of shares of the
capital stock of the Corporation owned by him. No certificate shall be issued
for partly paid shares.

         SECTION 2. STOCK CERTIFICATE SIGNATURE. The certificates for such stock
shall be numbered in the order in which they shall be issued and shall be signed
by the Chairman 


                                      -14-
<PAGE>

Secretary or an Assistant Secretary or the Treasurer of the Corporation, and its
seal shall be affixed thereto. If such certificate is countersigned (1) by a
transfer agent other than the Corporation or its employee, or, (2) by a
registrar other than the Corporation or its employee, the signatures of such
officers of the Corporation may be facsimiles. In case any officer of the
Corporation who has signed, or whose facsimile signature has been placed upon,
any such certificate shall have ceased to be such officer before such
certificate is issued, it may be issued by the Corporation with the same effect
as if he were such officer at the date of issue.

         SECTION 3. STOCK LEDGER. A record shall be kept by the Secretary or by
any other officer, employee or agent designated by the Board of Directors of the
name of each person, firm or corporation holding capital stock of the
Corporation, the number of shares represented by, and the respective dates of,
each certificate for such capital stock, and in case of cancellation of any such
certificate, the respective dates of cancellation.

         SECTION 4. CANCELLATION. Every certificate surrendered to the
Corporation for exchange or registration of transfer shall be canceled, and no
new certificate or certificates shall be issued in exchange for any existing
certificate until such existing certificate shall have been so canceled, except,
subject to Section 7 of this Article VII, in cases provided for by applicable
law.

transfers of shares of the capital stock of the Corporation shall be made on the
books of the Corporation by the registered holder thereof, or by his attorney
thereunto authorized by power of attorney duly executed and filed with the
Secretary of the Corporation or with a transfer clerk or a transfer agent
appointed as in Section 6 of this Article VII provided, and on surrender of the
certificate or certificates for such shares properly endorsed and the payment of
all taxes thereon. The person in whose name shares of stock stand on the books
of the Corporation shall be deemed the owner thereof for all purposes as regards
the Corporation; PROVIDED, HOWEVER, that whenever any transfer of shares shall
be made for collateral security, and not absolutely, it shall be so expressed in
the entry of the transfer if, when the certificates are presented to the
Corporation for transfer, both the transferor and the transferee request the
Corporation to do so.

         SECTION 6. REGULATIONS. The Board of Directors may make such rules and
regulations as it may deem expedient, not inconsistent with the Certificate of
Incorporation or these Bylaws, concerning the issue, transfer and registration
of certificates for shares of the stock of the Corporation. It may appoint, or
authorize any principal officer or officers to appoint, one or more transfer
clerks or one or more transfer agents and one or more registrars, and may
require all certificates of stock to bear the signature or signatures of any of
them.

         SECTION 7. LOST, STOLEN, DESTROYED OR MUTILATED CERTIFICATES. Before
any certificates for stock of the Corporation shall be issued in exchange for
certificates which 


                                      -15-
<PAGE>

shall become mutilated or shall be lost, stolen or destroyed, proper evidence of
such loss, theft, mutilation or destruction shall be procured for the Board of
Directors, if it so requires.

         SECTION 8. RECORD DATES. For the purpose of determining the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a date as a
record date for any such determination of stockholders. Such record date shall
not be more than sixty or less than ten days before the date of such meeting, or
more than sixty days prior to any other action.

                                  ARTICLE VIII
                            MISCELLANEOUS PROVISIONS

         SECTION 1. CORPORATE SEAL. The Board of Directors shall provide a

seal. The Board of Directors may authorize a duplicate seal to be kept and used
by any other officer.

Directors may authorize any person on behalf of the Corporation to attend, vote

(except the Corporation) in which the Corporation may hold stock.

         SECTION 3. DIVIDENDS. Subject to the provisions of the Certificate of
Incorporation, the Board of Directors may, out of funds legally available
therefore, at any regular or special meeting declare dividends upon the capital
stock of the Corporation as and when they deem expedient. Before declaring any
dividend there may be set apart out of any funds of the Corporation available
for dividends such sum or sums as the Directors from time to time in their
discretion deem proper for working capital or as a reserve fund to meet
contingencies or for equalizing dividends or for such other purposes as the
Board of Directors shall deem conducive to the interests of the Corporation.

                                   ARTICLE IX
                                   AMENDMENTS

         The Bylaws may be amended, altered, changed or repealed and new Bylaws
may be adopted (1) at any annual or special meeting of stockholders by the
affirmative vote of the holders of a majority of the voting power of the stock
issued and outstanding and entitled to vote thereat, provided, however, that any

                          ACCREDO HEALTH, INCORPORATED
                          1999 LONG-TERM INCENTIVE PLAN

                                    ARTICLE I
                                     PURPOSE

         1.1 GENERAL. The purpose of the Accredo Health, Incorporated 1999
Long-Term Incentive Plan (the "Plan") is to promote the success, and enhance the
value, of Accredo Health, Incorporated (the "Corporation"), by linking the
personal interests of its employees, officers, consultants and directors to
those of Corporation stockholders and by providing such persons with an
incentive for outstanding performance. The Plan is further intended to provide
flexibility to the Corporation in its ability to motivate, attract, and retain
the services of employees, officers, consultants and directors upon whose
judgment, interest, and special effort the successful conduct of the
Corporation's operation is largely dependent. Accordingly, the Plan permits the
grant of incentive awards from time to time to selected employees, officers,
directors, and consultants; provided, however, to the extent necessary to
preserve the employee benefits plan exemption under applicable state blue sky
laws, no non-employee director or consultant of the Corporation will be eligible
to receive Awards under the Plan until such time, if any, as the Corporation's
common stock shall be traded on a national securities exchange or on the Nasdaq
National Market.

                                    ARTICLE 2
                                 EFFECTIVE DATE

         2.1 EFFECTIVE DATE. The Plan shall be effective as of the date upon
which it shall be approved by the Board. However, the Plan shall be submitted to
the stockholders of the Corporation for approval within 12 months of the Board's
approval thereof. No Incentive Stock Options granted under the Plan may be
exercised prior to approval of the Plan by the stockholders and if the
stockholders fail to approve the Plan within 12 months of the Board's approval
thereof, any Incentive Stock Options previously granted hereunder shall be
automatically converted to Non-Qualified Stock Options without any further act.
In the discretion of the Committee, Awards may be made to Covered Employees
which are intended to constitute qualified performance-based compensation under
Code Section 162(m). Any such Awards shall be contingent upon the stockholders
having approved the Plan.

                                    ARTICLE 3
                                   DEFINITIONS

the Board. The Committee shall consist of two or more members of the Board. It

"non-employee directors" (within the meaning of Rule 16b-3 promulgated under the
1934 Act) and "outside directors" (within the meaning of Code Section 162(m) and
the regulations thereunder) to the extent that Rule 16b-3 and, if necessary for
relief from the limitation under Code Section 162(m) and such relief is sought
by the Corporation, Code Section 162(m), respectively, are applicable. However,
the mere fact that a Committee member shall fail to qualify under either of the
foregoing requirements shall not invalidate any Award made by the Committee
which Award is otherwise validly made under the Plan. The members of the
Committee shall be appointed by, and may be changed at any time and from time to
time in the discretion of, the Board. During any time that the Board is acting

Committee shall constitute a quorum. The acts of a majority of the members
present at any meeting at which a quorum is present, and acts approved
unanimously in writing by the members of the Committee in lieu of a meeting,
shall be deemed the acts of the Committee. Each member of the Committee is
entitled to, in good faith, rely or act upon any report or other information
furnished to that member by any officer or other employee of the Corporation or
any Parent or Subsidiary, the Corporation's independent certified public
accountants, or any executive compensation consultant or other professional

         forfeiture restrictions or restrictions on the exercisability of an

                  (g) Prescribe the form of each Award Agreement, which need not

         5.1. NUMBER OF SHARES. Subject to adjustment as provided in Section
14.1, the aggregate number of shares of Stock reserved and available for Awards
or which may be used to provide a basis of measurement for or to determine the

Restricted Stock or unrestricted Stock Awards.

         5.2. LAPSED AWARDS. To the extent that an Award is canceled,

Award will again be

<PAGE>

available for the grant of an Award under the Plan and shares subject to SARs or

maximum number of shares of Stock with respect to one or more Options and/or
SARs that may be granted during any one calendar year under the Plan to any one
Participant shall be 500,000. The maximum fair market value (measured as of the

any one Participant (less any consideration paid by the Participant for such
Award) during any one calendar year under the Plan shall be $2,000,000.

         6.1. GENERAL. Awards may be granted only to individuals who are
employees, officers, consultants or directors of the Corporation or a Parent or
Subsidiary; provided, however, that to the extent necessary to preserve the
employee benefits plan exemption under applicable state blue sky laws, no
non-employee director or consultant of the Corporation will be eligible to
receive Awards under the Plan until such time, if any, as the Corporation's
common stock shall be traded on a national securities exchange or on the Nasdaq
National Market.

                                  STOCK OPTIONS

         7.1. GENERAL. The Committee is authorized to grant Options to
Participants on the following terms and conditions:

                  (a) EXERCISE PRICE. The exercise price per share of Stock
         under an Option shall be determined by the Committee, provided that the
         exercise price for any Option shall not be less than the Fair Market
         Value as of the date of the grant.

                  (b) TIME AND CONDITIONS OF EXERCISE. The Committee shall
         determine the time or times at which an Option may be exercised in
         whole or in part. The Committee also shall determine the performance or
         other conditions, if any, that must be satisfied before all or part of
         an Option may be exercised. The Committee may waive any exercise
         provisions at any time in whole or in part based upon factors as the
         Committee may determine in its sole discretion so that the Option
         becomes exerciseable at an earlier date.



                                      -8-
<PAGE>

                  (c) PAYMENT. The Committee shall determine the methods by
         which the exercise price of an Option may be paid, the form of payment,
         including, without limitation, cash, shares of Stock, or other property
         (including "cashless exercise" arrangements), and the methods by which
         shares of Stock shall be delivered or deemed to be delivered to
         Participants; provided that if shares of Stock surrendered in payment
         of the exercise price were themselves acquired otherwise than on the
         open market, such shares shall have been held by the Participant for at
         least six months.

                  (d) EVIDENCE OF GRANT. All Options shall be evidenced by a
         written Award Agreement between the Corporation and the Participant.
         The Award Agreement shall include such provisions, not inconsistent
         with the Plan, as may be specified by the Committee.

                  (e) ADDITIONAL OPTIONS UPON EXERCISE. The Committee may, in
         its sole discretion, provide in an Award Agreement, or in an amendment
         thereto, for the automatic grant of a new Option to any Participant who
         delivers shares of Stock as full or partial payment of the exercise
         price of the original Option. Any new Option granted in such a case (i)
         shall be for the same number of shares of Stock as the Participant
         delivered in exercising the original Option, (ii) shall have an
         exercise price of 100% of the Fair Market Value of the surrendered
         shares of Stock on the date of exercise of the original Option (the
         grant date for the new Option), and (iii) shall have a term equal to
         the unexpired term of the original Option.

         7.2. INCENTIVE STOCK OPTIONS. The terms of any Incentive Stock Options
granted under the Plan must comply with the following additional rules:

                  (a) EXERCISE PRICE. The exercise price per share of Stock
         shall be set by the Committee, provided that the exercise price for any
         Incentive Stock Option shall not be less than the Fair Market Value as
         of the date of the grant.

                  (b) EXERCISE. In no event may any Incentive Stock Option be
         exercisable for more than ten years from the date of its grant.

                  (c) LAPSE OF OPTION. An Incentive Stock Option shall lapse
         under the earliest of the following circumstances; provided, however,
         that the Committee may, prior to the lapse of the Incentive Stock
         Option under the circumstances described in paragraphs (3), (4) and (5)
         below, provide in writing that the Option will extend until a later
         date, but if the Option is exercised after the dates specified in
         paragraphs (3), (4) and (5) below, it will automatically become a
         Non-Qualified Stock Option:



                                      -9-
<PAGE>

                           (1) The Incentive Stock Option shall lapse as of the
                  option expiration date set forth in the Award Agreement.

                           (2) The Incentive Stock Option shall lapse ten years
                  after it is granted, unless an earlier time is set in the
                  Award Agreement.

                           (3) If the Participant terminates employment for any
                  reason other than as provided in paragraph (4) or (5) below,
                  the Incentive Stock Option shall lapse, unless it is
                  previously exercised, three months after the Participant's
                  termination of employment; provided, however, that if the
                  Participant's employment is terminated by the Corporation for
                  cause or by the Participant without the consent of the
                  Corporation, the Incentive Stock Option shall (to the extent
                  not previously exercised) lapse immediately.

                           (4) If the Participant terminates employment by
                  reason of his Disability, the Incentive Stock Option shall
                  lapse, unless it is previously exercised, one year after the
                  Participant's termination of employment.

                           (5) If the Participant dies while employed, or during
                  the three-month period described in paragraph (3) or during
                  the one-year period described in paragraph (4) and before the
                  Option otherwise lapses, the Option shall lapse one year after
                  the Participant's death. Upon the Participant's death, any
                  exercisable Incentive Stock Options may be exercised by the
                  Participant's estate.

                  Unless the exercisability of the Incentive Stock Option is
         accelerated as provided in Article 13, if a Participant exercises an
         Option after termination of employment, the Option may be exercised
         only with respect to the shares that were otherwise vested on the
         Participant's termination of employment.

                  (d) INDIVIDUAL DOLLAR LIMITATION. The aggregate Fair Market
         Value (determined as of the time an Award is made) of all shares of
         Stock with respect to which Incentive Stock Options are first
         exercisable by a Participant in any calendar year may not exceed
         $100,000.00.

                  (e) TEN PERCENT OWNERS. No Incentive Stock Option shall be
         granted to any individual who, at the date of grant, owns stock
         possessing more than ten percent of the total combined voting power of
         all classes of stock of the Corporation or any Parent or Subsidiary
         unless the exercise price per share of such Option is at least 110% of
         the Fair Market Value per share of Stock at the date of grant and the
         Option expires no later than five years after the date of grant.

                  (f) EXPIRATION OF INCENTIVE STOCK OPTIONS. No Award of an
         Incentive Stock Option may be made pursuant to the Plan after the day
         immediately prior to the tenth anniversary of the Effective Date.



                                      -10-
<PAGE>

                  (g) RIGHT TO EXERCISE. During a Participant's lifetime, an
         Incentive Stock Option may be exercised only by the Participant or, in
         the case of the Participant's Disability, by the Participant's guardian
         or legal representative.

                  (h) DIRECTORS. The Committee may not grant an Incentive Stock
         Option to a non-employee director. The Committee may grant an Incentive
         Stock Option to a director who is also an employee of the Corporation
         or Parent or Subsidiary but only in that individual's position as an
         employee and not as a director.

                            STOCK APPRECIATION RIGHTS

         8.1. GRANT OF SARS. The Committee is authorized to grant SARs to
Participants on the following terms and conditions:

                  (a) RIGHT TO PAYMENT. Upon the exercise of a Stock
         Appreciation Right, the Participant to whom it is granted has the right
         to receive the excess, if any, of:

                          (1) The Fair Market Value of one share of Stock on
                 the date of exercise; over

                          (2) The grant price of the Stock Appreciation Right as
                 determined by the Committee, which shall not be less than the
                 Fair Market Value of one share of Stock on the date of grant.

                  (b) OTHER TERMS. All awards of Stock Appreciation Rights shall
         be evidenced by an Award Agreement. The terms, methods of exercise,
         methods of settlement, form of consideration payable in settlement, and
         any other terms and conditions of any Stock Appreciation Right shall be
         determined by the Committee at the time of the grant of the Award and
         shall be reflected in the Award Agreement.

                                    ARTICLE 9
                                PERFORMANCE UNITS

         9.1. GRANT OF PERFORMANCE UNITS. The Committee is authorized to grant
Performance Units to Participants on such terms and conditions as may be
selected by the Committee. The Committee shall have the complete discretion to
determine the number of Performance Units granted to each Participant. All
Awards of Performance Units shall be evidenced by an Award Agreement.



                                      -11-
<PAGE>

         9.2. RIGHT TO PAYMENT. A grant of Performance Units gives the
Participant rights, valued as determined by the Committee, and payable to, or
exercisable by, the Participant to whom the Performance Units are granted, in
whole or in part, as the Committee shall establish at grant or thereafter. The
Committee shall set performance goals and other terms or conditions to payment
of the Performance Units in its discretion which, depending on the extent to
which they are met, will determine the number and value of Performance Units
that will be paid to the Participant.

         9.3. OTHER TERMS. Performance Units may be payable in cash, Stock, or
other property, and have such other terms and conditions as determined by the
Committee and reflected in the Award Agreement.

                                   ARTICLE 10
                             RESTRICTED STOCK AWARDS

         10.1. GRANT OF RESTRICTED STOCK. The Committee is authorized to make
Awards of Restricted Stock to Participants in such amounts and subject to such
terms and conditions as may be selected by the Committee. All Awards of
Restricted Stock shall be evidenced by a Restricted Stock Award Agreement.

         10.2. ISSUANCE AND RESTRICTIONS. Restricted Stock shall be subject to
such restrictions on transferability and other restrictions as the Committee may
impose (including, without limitation, limitations on the right to vote
Restricted Stock or the right to receive dividends on the Restricted Stock).
These restrictions may lapse separately or in combination at such times, under
such circumstances, in such installments, upon the satisfaction of performance
goals or otherwise, as the Committee determines at the time of the grant of the
Award or thereafter.

         10.3. FORFEITURE. Except as otherwise determined by the Committee at
the time of the grant of the Award or thereafter, upon termination of employment
during the applicable restriction period or upon failure to satisfy a
performance goal during the applicable restriction period, Restricted Stock that
is at that time subject to restrictions shall be forfeited and reacquired by the
Corporation; provided, however, that the Committee may provide in any Award
Agreement that restrictions or forfeiture conditions relating to Restricted
Stock will be waived in whole or in part in the event of terminations resulting
from specified causes, and the Committee may in other cases waive in whole or in
part restrictions or forfeiture conditions relating to Restricted Stock.

         10.4. CERTIFICATES FOR RESTRICTED STOCK. Restricted Stock granted under
the Plan may be evidenced in such manner as the Committee shall determine. If
certificates representing shares of Restricted Stock are registered in the name
of the Participant, certificates must bear an appropriate legend referring to
the terms, conditions, and restrictions applicable to such Restricted Stock.

                              DIVIDEND EQUIVALENTS

         11.1 GRANT OF DIVIDEND EQUIVALENTS. The Committee is authorized to
grant Dividend Equivalents to Participants subject to such terms and conditions
as may be selected by the Committee. Dividend Equivalents shall entitle the
Participant to receive payments equal to dividends with respect to all or a
portion of the number of shares of Stock subject to an Award, as determined by
the Committee. The Committee may provide that Dividend Equivalents be paid or
distributed when accrued or be deemed to have been reinvested in additional
shares of Stock, or otherwise reinvested.

                                   ARTICLE 12
                            OTHER STOCK-BASED AWARDS

         12.1. GRANT OF OTHER STOCK-BASED AWARDS. The Committee is authorized,
subject to limitations under applicable law, to grant to Participants such other
Awards that are payable in, valued in whole or in part by reference to, or
otherwise based on or related to shares of Stock, as deemed by the Committee to
be consistent with the purposes of the Plan, including without limitation shares
of Stock awarded purely as a "bonus" and not subject to any restrictions or
conditions, convertible or exchangeable debt securities, other rights
convertible or exchangeable into shares of Stock, and Awards valued by reference
to book value of shares of Stock or the value of securities of or the
performance of specified Parents or Subsidiaries. The Committee shall determine
the terms and conditions of such Awards.

                                   ARTICLE 13
                         PROVISIONS APPLICABLE TO AWARDS

         13.1. STAND-ALONE, TANDEM, AND SUBSTITUTE AWARDS. Awards granted under
the Plan may, in the discretion of the Committee, be granted either alone or in
addition to, in tandem with, or in substitution for, any other Award granted
under the Plan. If an Award is granted in substitution for another Award, the
Committee may require the surrender of such other Award in consideration of the
grant of the new Award. Awards granted in addition to or in tandem with other
Awards may be granted either at the same time as or at a different time from the
grant of such other Awards.

         13.2. EXCHANGE PROVISIONS. The Committee may at any time offer to
exchange or buy out any previously granted Award for a payment in cash, Stock,
or another Award (subject to Section 14.1), based on the terms and conditions
the Committee determines and communicates to the Participant at the time the
offer is made and after taking into account the tax, securities and accounting
effects of such an exchange.

         13.3. TERM OF AWARD. The term of each Award shall be for the period as
determined by the Committee, provided that in no event shall the term of any
Incentive



                                      -13-
<PAGE>

Stock Option or a Stock Appreciation Right granted in tandem with the Incentive
Stock Option exceed a period of ten years from the date of its grant (or, if
Section 7.2(e) applies, five years from the date of its grant).

         13.4. FORM OF PAYMENT FOR AWARDS. Subject to the terms of the Plan and
any applicable law or Award Agreement, payments or transfers to be made by the
Corporation or a Parent or Subsidiary on the grant or exercise of an Award may
be made in such form as the Committee determines at or after the time of grant,
including without limitation, cash, Stock, other Awards, or other property, or
any combination, and may be made in a single payment or transfer, in
installments, or on a deferred basis, in each case determined in accordance with
rules adopted by, and at the discretion of, the Committee.

         13.5. LIMITS ON TRANSFER. No right or interest of a Participant in any
unexercised or restricted Award may be pledged, encumbered, or hypothecated to
or in favor of any party other than the Corporation or a Parent or Subsidiary,
or shall be subject to any lien, obligation, or liability of such Participant to
any other party other than the Corporation or a Parent or Subsidiary. No
unexercised or restricted Award shall be assignable or transferable by a
Participant other than by will or the laws of descent and distribution or,
except in the case of an Incentive Stock Option, pursuant to a domestic
relations order that would satisfy Section 414(p)(1)(A) of the Code if such
Section applied to an Award under the Plan; provided, however, that the
Committee may (but need not) permit other transfers where the Committee
concludes that such transferability (i) does not result in accelerated taxation,
(ii) does not cause any Option intended to be an incentive stock option to fail
to be described in Code Section 422(b), and (iii) is otherwise appropriate and
desirable, taking into account any factors deemed relevant, including without
limitation, any state or federal tax or securities laws or regulations
applicable to transferable Awards.

         13.6. STOCK CERTIFICATES. All Stock certificates delivered under the
Plan are subject to any stop-transfer orders and other restrictions as the
Committee deems necessary or advisable to comply with federal or state
securities laws, rules and regulations and the rules of any national securities
exchange or automated quotation system on which the Stock is listed, quoted, or
traded. The Committee may place legends on any Stock certificate to reference
restrictions applicable to the Stock.

         13.7 ACCELERATION UPON DEATH, RETIREMENT OR DISABILITY. Notwithstanding
any other provision in the Plan or any Participant's Award Agreement to the
contrary, upon the Participant's death, Retirement or Disability during his
employment or service as a consultant or director, all outstanding Options,
Stock Appreciation Rights, and other Awards in the nature of rights that may be
exercised shall become fully exercisable and all restrictions on outstanding
Awards shall lapse. Any Option or Stock Appreciation Rights Awards shall
thereafter continue or lapse in accordance with the other provisions of the Plan
and the Award Agreement. To the extent that this provision causes Incentive
Stock Options to exceed the dollar limitation set forth in Section 7.2(d), the
excess Options shall be deemed to be Non-Qualified Stock Options.



                                      -14-
<PAGE>

         13.8. ACCELERATION UPON A CHANGE IN CONTROL. Except as otherwise
provided in the Award Agreement, upon the occurrence of a Change in Control, all
outstanding Options, Stock Appreciation Rights, and other Awards in the nature
of rights that may be exercised shall become fully exercisable and all
restrictions on outstanding Awards shall lapse; provided, however that such
acceleration will not occur if, in the opinion of the Corporation's accountants,
such acceleration would preclude the use of "pooling of interest" accounting
treatment for a Change in Control transaction that (a) would otherwise qualify
for such accounting treatment, and (b) is contingent upon qualifying for such
accounting treatment. To the extent that this provision causes Incentive Stock
Options to exceed the dollar limitation set forth in Section 7.2(d), the excess
Options shall be deemed to be Non-Qualified Stock Options.

         13.9. ACCELERATION UPON CERTAIN EVENTS NOT CONSTITUTING A CHANGE IN
CONTROL. In the event of the occurrence of any circumstance, transaction or
event not constituting a Change in Control (as defined in Section 3.1) but which
the Board of Directors deems to be, or to be reasonably likely to lead to, an
effective change in control of the Corporation of a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of the 1934
Act, the Committee may in its sole discretion declare all outstanding Options,
Stock Appreciation Rights, and other Awards in the nature of rights that may be
exercised to be fully exercisable, and/or all restrictions on all outstanding
Awards to have lapsed, in each case, as of such date as the Committee may, in
its sole discretion, declare, which may be on or before the consummation of such
transaction or event. To the extent that this provision causes Incentive Stock
Options to exceed the dollar limitation set forth in Section 7.2(d), the excess
Options shall be deemed to be Non-Qualified Stock Options.

         13.10. ACCELERATION FOR ANY OTHER REASON. Regardless of whether an
event has occurred as described in Section 13.8 or 13.9 above, the Committee may
in its sole discretion at any time determine that all or a portion of a
Participant's Options, Stock Appreciation Rights, and other Awards in the nature
of rights that may be exercised shall become fully or partially exercisable,
and/or that all or a part of the restrictions on all or a portion of the
outstanding Awards shall lapse, in each case, as of such date as the Committee
may, in its sole discretion, declare. The Committee may discriminate among
Participants and among Awards granted to a Participant in exercising its
discretion pursuant to this Section 13.10.

         13.11 EFFECT OF ACCELERATION. If an Award is accelerated under Section
13.8 or 13.9, the Committee may, in its sole discretion, provide (i) that the
Award will expire after a designated period of time after such acceleration to
the extent not then exercised, (ii) that the Award will be settled in cash
rather than Stock, (iii) that the Award will be assumed by another party to the
transaction giving rise to the acceleration or otherwise be equitably converted
in connection with such transaction, or (iv) any combination of the foregoing.
The Committee's determination need not be uniform and



                                      -15-
<PAGE>

may be different for different Participants whether or not such Participants are
similarly situated.

         13.12. PERFORMANCE GOALS. The Committee may (but need not) determine
that any Award granted pursuant to this Plan to a Participant (including, but
not limited to, Participants who are Covered Employees) shall be determined
solely on the basis of (a) the achievement by the Corporation or a Parent or
Subsidiary of a specified target return, or target growth in return, on equity
or assets, (b) the Company's total shareholder return (stock price appreciation
plus reinvested dividends) relative to a defined comparison group or target over
a specific performance period, (c) the Corporation's, Parent's or Subsidiary's
stock price, (d) the achievement by an individual or a business unit of the
Corporation, Parent or Subsidiary of a specified target, or target growth in,
revenues, net income or earnings per share, (e) the achievement of objectively
determinable goals with respect to service or product delivery, service or
product quality, customer satisfaction, meeting budgets and/or retention of
employees or (f) any combination of the goals set forth in (a) through (e)
above. If an Award is made on such basis, the Committee shall establish goals
prior to the beginning of the period for which such performance goal relates (or
such later date as may be permitted under Code Section 162(m) or the regulations
thereunder) and the Committee may for any reason reduce (but not increase) any
Award, notwithstanding the achievement of a specified goal. Any payment of an
Award granted with performance goals shall be conditioned on the written
certification of the Committee in each case that the performance goals and any
other material conditions were satisfied.

         13.13. TERMINATION OF EMPLOYMENT. Whether military, government or other
service or other leave of absence shall constitute a termination of employment
shall be determined in each case by the Committee at its discretion, and any
determination by the Committee shall be final and conclusive. A termination of
employment shall not occur in a circumstance in which a Participant transfers
from the Corporation to one of its Parents or Subsidiaries, transfers from a
Parent or Subsidiary to the Corporation, or transfers from one Parent or
Subsidiary to another Parent or Subsidiary.

                                   ARTICLE 14
                          CHANGES IN CAPITAL STRUCTURE

         14.1. GENERAL. In the event a stock dividend is declared upon the
Stock, the authorization limits under Section 5.1 and 5.4 shall be increased
proportionately, and the shares of Stock then subject to each Award shall be
increased proportionately without any change in the aggregate purchase price
therefor. In the event the Stock shall be changed into or exchanged for a
different number or class of shares of stock or securities of the Corporation or
of another corporation, whether through reorganization, recapitalization,
reclassification, share exchange, stock split-up, combination of shares, merger
or consolidation, the authorization limits under Section 5.1 and 5.4 shall be
increased proportionately, and there shall be substituted for each such share of
Stock then subject to each Award the number and class of shares into which each
outstanding share of Stock



                                      -16-
<PAGE>

shall be so exchanged, all without any change in the aggregate purchase price
for the shares then subject to each Award, or, subject to Section 15.2, there
shall be made such other equitable adjustment as the Committee shall approve.

                                   ARTICLE 15
                     AMENDMENT, MODIFICATION AND TERMINATION

         15.1. AMENDMENT, MODIFICATION AND TERMINATION. The Board or the
Committee may, at any time and from time to time, amend, modify or terminate the
Plan without stockholder approval; provided, however, that the Board or
Committee may condition any amendment or modification on the approval of
stockholders of the Corporation if such approval is necessary or deemed
advisable with respect to tax, securities or other applicable laws, policies or
regulations.

         15.2 AWARDS PREVIOUSLY GRANTED. At any time and from time to time, the
Committee may amend, modify or terminate any outstanding Award without approval
of the Participant; provided, however, that, subject to the terms of the
applicable Award Agreement, such amendment, modification or termination shall
not, without the Participant's consent, reduce or diminish the value of such
Award determined as if the Award had been exercised, vested, cashed in or
otherwise settled on the date of such amendment or termination. No termination,
amendment, or modification of the Plan shall adversely affect any Award
previously granted under the Plan, without the written consent of the
Participant.

                                   ARTICLE 16
                               GENERAL PROVISIONS

         16.1. NO RIGHTS TO AWARDS. No Participant or any eligible participant
shall have any claim to be granted any Award under the Plan, and neither the
Corporation nor the Committee is obligated to treat Participants or eligible
participants uniformly.

         16.2. NO STOCKHOLDER RIGHTS. No Award gives the Participant any of the
rights of a stockholder of the Corporation unless and until shares of Stock are
in fact issued to such person in connection with such Award.

         16.3. WITHHOLDING. The Corporation or any Parent or Subsidiary shall
have the authority and the right to deduct or withhold, or require a Participant
to remit to the Corporation, an amount sufficient to satisfy federal, state, and
local taxes (including the Participant's FICA obligation) required by law to be
withheld with respect to any taxable event arising as a result of the Plan. With
respect to withholding required upon any taxable event under the Plan, the
Committee may, at the time the Award is granted or thereafter, require that any
such withholding requirement be satisfied, in whole or in part, by withholding
shares of Stock having a Fair Market Value on the date of withholding equal to
the amount required to be withheld for tax purposes, all in accordance with such
procedures as the Committee establishes.



                                      -17-

         16.4. NO RIGHT TO CONTINUED SERVICE. Nothing in the Plan or any Award
Agreement shall interfere with or limit in any way the right of the Corporation
or any Parent or Subsidiary to terminate any Participant's employment or status
as an officer, director or consultant at any time, nor confer upon any
Participant any right to continue as an employee, officer, director or
consultant of the Corporation or any Parent or Subsidiary.

         l6.5. UNFUNDED STATUS OF AWARDS. The Plan is intended to be an
"unfunded" plan for incentive and deferred compensation. With respect to any
payments not yet made to a Participant pursuant to an Award, nothing contained
in the Plan or any Award Agreement shall give the Participant any rights that
are greater than those of a general creditor of the Corporation or any Parent or
Subsidiary.

         16.6. INDEMNIFICATION. To the extent allowable under applicable law,
each member of the Committee shall be indemnified and held harmless by the
Corporation from any loss, cost, liability, or expense that may be imposed upon
or reasonably incurred by such member in connection with or resulting from any
claim, action, suit, or proceeding to which such member may be a party or in
which he may be involved by reason of any action or failure to act under the
Plan and against and from any and all amounts paid by such member in
satisfaction of judgment in such action, suit, or proceeding against him
provided he gives the Corporation an opportunity, at its own expense, to handle
and defend the same before he undertakes to handle and defend it on his own
behalf. The foregoing right of indemnification shall not be exclusive of any
other rights of indemnification to which such persons may be entitled under the
Corporation's Certificate of Incorporation or Bylaws, as a matter of law, or
otherwise, or any power that the Corporation may have to indemnify them or hold
them harmless.

         16.7. RELATIONSHIP TO OTHER BENEFITS. No payment under the Plan shall
be taken into account in determining any benefits under any pension, retirement,
savings, profit sharing, group insurance, welfare or benefit plan of the
Corporation or any Parent or Subsidiary unless provided otherwise in such other
plan.

         16.8. EXPENSES. The expenses of administering the Plan shall be borne
by the Corporation and its Parents or Subsidiaries.

         16.9. TITLES AND HEADINGS. The titles and headings of the Sections in
the Plan are for convenience of reference only, and in the event of any
conflict, the text of the Plan, rather than such titles or headings, shall
control.

         16.10. GENDER AND NUMBER. Except where otherwise indicated by the
context, any masculine term used herein also shall include the feminine; the
plural shall include the singular and the singular shall include the plural.



                                      -18-
<PAGE>

         16.11. FRACTIONAL SHARES. No fractional shares of Stock shall be issued
and the Committee shall determine, in its discretion, whether cash shall be
given in lieu of fractional shares or whether such fractional shares shall be
eliminated by rounding up.

         16.12. GOVERNMENT AND OTHER REGULATIONS. The obligation of the
Corporation to make payment of awards in Stock or otherwise shall be subject to
all applicable laws, rules, and regulations, and to such approvals by government
agencies as may be required. The Corporation shall be under no obligation to
register under the 1933 Act, or any state securities act, any of the shares of
Stock paid under the Plan. The shares paid under the Plan may in certain
circumstances be exempt from registration under the 1933 Act, and the
Corporation may restrict the transfer of such shares in such manner as it deems
advisable to ensure the availability of any such exemption.

         16.13. GOVERNING LAW. To the extent not governed by federal law, the
Plan and all Award Agreements shall be construed in accordance with and governed
by the laws of the State of Tennessee.

         16.14 ADDITIONAL PROVISIONS. Each Award Agreement may contain such
other terms and conditions as the Committee may determine; provided that such
other terms and conditions are not inconsistent with the provisions of this
Plan.

         16.15 CODE SECTION 162(M). The deduction limits of Code Section 162(m)
and the regulation thereunder do not apply to the Corporation until such time,
if any, as any class of the Corporation's common equity securities is registered
under Section 12 of the 1934 Act or the Corporation otherwise meets the
definition of a "publicly held corporation" under Treasury Regulation
1.162-27(c) or any successor provision. Upon becoming a publicly held
corporation, the deduction limits of Code Section 162(m) and the regulations
thereunder shall not apply to compensation payable under this Plan until the
expiration of the reliance period described in Treasury Regulation 1.162-27(f)
or any successor regulation.

         The foregoing is hereby acknowledged as being the Accredo Health,
Incorporated 1999 Long-Term Incentive Plan as adopted by the Board of Directors
of the Corporation on April __, 1999 and approved by the stockholders of the
Corporation on _______________, 1999.

                                   ARTICLE III
                          ELIGIBILITY AND PARTICIPATION

         3.1 ELIGIBILITY. Each Employee who is an Employee regularly scheduled
to work at least 20 hours each week and at least five months each calendar year
shall be eligible to participate in the Plan as of the later of:

         (a) the Offering Date immediately following the Employee's last date of
hire by an Employer; or

         (b) the Effective Date.

         On each Offering Date, Options will automatically be granted to all
Employees then eligible to participate in the Plan; provided, however, that no
Employee shall be granted an Option for an Offering Period if, immediately after
the grant, the Employee would own stock, and/or hold outstanding options to
purchase stock, possessing five percent or more of the total combined voting
power or value of all classes of stock of the Corporation or any Subsidiary. For
purposes of this Section, the attribution rules of Code Section 424(d) shall
apply in determining stock ownership of any Employee. If an Employee is granted
an Option for an Offering Period and such Employee does not participate in the
Plan for such Offering Period, such Option will be deemed never to have been
granted for purposes of applying the $25,000 annual limitation described in
Section 5.2.

         3.2 INITIAL PARTICIPATION. An Eligible Employee having been granted an
Option under Section 3.1 may submit a Request Form to the Administrator to
participate in the Plan for an Offering Period. The Request Form shall authorize
a regular payroll deduction from the Employee's Compensation for the Offering
Period, subject to the limits and procedures described in Article VI. A
Participant's Request Form authorizing a regular payroll deduction shall remain
effective from Offering Period to Offering Period until amended or canceled
under Section 6.3.

         3.3 LEAVE OF ABSENCE. For purposes of Section 3.1, an individual on a
leave of absence from an Employer shall be deemed to be an Employee for the
first 90 days of such leave. For purposes of this Plan, such individual's
employment with the Employer shall be deemed to terminate at the close of
business on the 90th day of the leave, unless the individual has returned to
regular employment with an Employer before the close of business on such 90th
day. Termination of any individual's leave of absence by an Employer, other than
on account of a return to employment with an Employer, shall be deemed to
terminate an individual's employment with the Employer for all purposes of the
Plan.

                                   ARTICLE IV
                                 STOCK AVAILABLE

         4.1 IN GENERAL. Subject to the adjustments in Sections 4.2 and 4.3, an
aggregate of 135,000 shares of Common Stock shall be available for purchase by
Participants pursuant to the provisions of the Plan. These shares may be
authorized and unissued shares or may be shares issued and subsequently acquired
by the Corporation. If an Option under the Plan expires or terminates for any
reason without having been exercised in whole or part, the shares subject to
such Option that are not purchased shall again be available for subsequent
Option grants under the Plan. If the total number of shares of Common Stock for
which Options are exercised on any Purchase Date exceeds the maximum number of
shares then available under the Plan, the Committee shall make a pro rata
allocation of the shares available in as nearly a uniform manner as shall be
practicable and as it shall determine to be equitable; and the balance of the
cash credited to Participants' Contribution Accounts shall be distributed to the
Participants as soon as practicable.

         4.2 ADJUSTMENT IN EVENT OF CHANGES IN CAPITALIZATION. In the event of a
stock dividend, stock split or combination of shares, recapitalization or other
change in the Corporation's capitalization, or other distribution with respect
to holders of the Corporation's Common Stock other than normal cash dividends,
an automatic adjustment shall be made in the number and kind of shares as to
which outstanding Options or portions thereof then unexercised shall be
exercisable and in the available shares set forth in Section 4.1, so that the
proportionate interest of the Participants shall be maintained as before the
occurrence of such event. This adjustment in outstanding Options shall be made
without change in the total price applicable to the unexercised portion of such
Options and with a corresponding adjustment in the Purchase Price per share;
provided, however, that in no event shall any adjustment be made that would
cause any Option to fail to qualify as an option pursuant to an employee stock
purchase plan within the meaning of Section 423 of the Code.

         4.3 DISSOLUTION, LIQUIDATION, OR MERGER. Upon the dissolution or
liquidation of the Corporation, or upon a reorganization, merger, or
consolidation of the Corporation with one or more corporations in which the
Corporation is not the surviving corporation, or upon a sale of substantially
all of the property or stock of the Corporation 

                                       5
<PAGE>

to another corporation, the holder of each Option then outstanding under the
Plan shall be entitled to receive at the next Purchase Date upon the exercise of
such Option for each share as to which such Option shall be exercised, as nearly
as reasonably may be determined, the cash, securities, or property which a
holder of one share of the Common Stock was entitled to receive upon and at the
time of such transaction. The Board shall take such steps in connection with
these transactions as the Board deems necessary or appropriate to assure that
the provisions of this Section shall thereafter be applicable, as nearly as
reasonably may be determined, in relation to the cash, securities, or property
which the holder of the Option may thereafter be entitled to receive. In lieu of
the foregoing, the Committee may terminate the Plan in accordance with Section
8.2.

                                OPTION PROVISIONS

         5.1 PURCHASE PRICE. The Purchase Price of a share of Common Stock
purchased for a Participant pursuant to each exercise of an Option shall be the
lesser of:

         (a) 85 percent of the Fair Market Value of a share of Common Stock on
the Offering Date; or

         (b) 85 percent of the Fair Market Value of a share of Common Stock on
the Purchase Date.

         5.2 CALENDAR YEAR $25,000 LIMIT. Notwithstanding anything else
contained herein, no Employee may be granted an Option for any Offering Period
which permits such Employee's rights to purchase Common Stock under this Plan
and any other qualified employee stock purchase plan (within the meaning of Code
Section 423) of the Corporation and its Subsidiaries to accrue at a rate which
exceeds $25,000 of Fair Market Value of such Common Stock for each calendar year
in which an Option is outstanding at any time. For purposes of this Section,
Fair Market Value shall be determined as of the Offering Date.

         5.3 OFFERING PERIOD LIMIT. Notwithstanding anything else contained
herein, the maximum number of shares of Common Stock that an Eligible Employee
may purchase in any Offering Period is 2,500 shares.

                                   ARTICLE VI
                             PURCHASING COMMON STOCK

         6.1 PARTICIPANT'S CONTRIBUTION ACCOUNT. The Administrator shall
establish a book account in the name of each Participant for each Offering
Period. As discussed in Section 6.2 below, a Participant's payroll deductions
shall be credited to the Participant's Contribution Account, without interest,
until such cash is withdrawn, distributed, or used to purchase Common Stock as
described below.

                                       6
<PAGE>

         During such time, if any, as the Corporation participates in a Direct
Registration System, shares of Common Stock acquired upon exercise of an Option
shall be directly registered in the name of the Participant. If the Corporation
does not participate in a Direct Registration System, then until distribution is
requested by a Participant pursuant to Article VII, stock certificates
evidencing the Participant's shares of Common Stock acquired upon exercise of an
Option shall be held by the Corporation as the nominee for the Participant.
These shares shall be credited to the Participant's Stock Account. Certificates
shall be held by the Corporation as nominee for Participants solely as a matter
of convenience. A Participant shall have all ownership rights as to the shares
credited to his or her Stock Account, and the Corporation shall have no
ownership or other rights of any kind with respect to any such certificates or
the shares represented thereby.

         All cash received or held by the Corporation under the Plan may be used
by the Corporation for any corporate purpose. The Corporation shall not be
obligated to segregate any assets held under the Plan.

         6.2 PAYROLL DEDUCTIONS; DIVIDENDS.

         (a) PAYROLL DEDUCTIONS. By submitting a Request Form at any time before
an Offering Period in accordance with rules adopted by the Committee, an
Eligible Employee may authorize a payroll deduction to purchase Common Stock
under the Plan for the Offering Period. The payroll deduction shall be effective
on the first pay period during the Offering Period commencing after receipt of
the Request Form by the Administrator. The payroll deduction shall be in any
whole percentage up to a maximum of ten percent (10%) of such Employee's
Compensation payable each pay period, and at any other time an element of
Compensation is payable. A Participant's payroll deduction shall not be less
than one percent (1%) of such Employee's Compensation payable each payroll
period.

         (b) DIVIDENDS. Cash dividends paid on Common Stock which is credited to
a Participant's Stock Account as of the dividend payment date shall be credited
to the Participant's Stock Account and paid to the Participant as soon as
practicable.

         6.3 DISCONTINUANCE. A Participant may discontinue his or her payroll
deductions for an Offering Period by filing a new Request Form with the
Administrator. This discontinuance shall be effective on the first pay period
commencing at least 30 days after receipt of the Request Form by the
Administrator. A Participant who discontinues his or her payroll deductions for
an Offering Period may not resume participation in the Plan until the following
Offering Period.

         Any amount held in the Participant's Contribution Account for an
Offering Period after the effective date of the discontinuance of his or her
payroll deductions will either be refunded or used to purchase Common Stock in
accordance with Section 7.1.

<PAGE>

         6.4 LEAVE OF ABSENCE; TRANSFER TO INELIGIBLE STATUS. If a Participant
either begins a leave of absence, is transferred to employment with a Subsidiary
not participating in the Plan, or remains employed with an Employer but is no
longer eligible to participate in the Plan, the Participant shall cease to be
eligible for payroll deductions to his or her Contribution Account pursuant to
Section 6.2. The cash standing to the credit of the Participant's Contribution
Account shall become subject to the provisions of Section 7.1.

         If the Participant returns from the leave of absence before being
deemed to have ceased employment with the Employer under Section 3.3, or again
becomes eligible to participate in the Plan, the Request Form, if any, in effect
immediately before the leave of absence or disqualifying change in employment
status shall be deemed void and the Participant must again complete a new
Request Form to resume participation in the Plan.

         6.5 AUTOMATIC EXERCISE. Unless the cash credited to a Participant's
Contribution Account is withdrawn or distributed as provided in Article VII, his
or her Option shall be deemed to have been exercised automatically on each
Purchase Date, for the purchase of the number of full shares of Common Stock
which the cash credited to his or her Contribution Account at that time will
purchase at the Purchase Price. If there is a cash balance remaining in the
Participant's Contribution Account at the end of an Offering Period representing
the exercise price for a fractional share of Common Stock, such balance shall be
retained in the Participant's Contribution Account for the next Offering Period,
unless the Participant requests that it be refunded, without interest. Any other
cash balance remaining in the Participant's Contribution Account at the end of
an Offering Period shall be refunded to the Participant, without interest. The
amount of cash that may be used to purchase shares of Common Stock may not
exceed the Compensation restrictions set forth in Section 6.2.

         If the cash credited to a Participant's Contribution Account on the
Purchase Date exceeds the applicable Compensation restrictions of Section 6.2 or
exceeds the amount necessary to purchase the maximum number of shares of Common
Stock available during the Offering Period, such excess cash shall be refunded
to the Participant. The excess cash may not be used to purchase shares of Common
Stock nor retained in the Participant's Contribution Account for a future
Offering Period.

         Each Participant shall receive a statement on an annual basis
indicating the number of shares credited to his or her Stock Account under the
Plan.

         6.6 LISTING, REGISTRATION, AND QUALIFICATION OF SHARES. The granting of
Options for, and the sale and delivery of, Common Stock under the Plan shall be
subject to the effecting by the Corporation of any listing, registration, or
qualification of the shares subject to that Option upon any securities exchange
or under any federal or state law, or the obtaining of the consent or approval
of any governmental regulatory body deemed necessary or desirable for the
issuance or purchase of the shares covered.

         7.1 DISCONTINUANCE OF DEDUCTIONS; LEAVE OF ABSENCE; TRANSFER TO
INELIGIBLE STATUS. In the event of a Participant's complete discontinuance of
payroll deductions under Section 6.3 or a Participant's leave of absence or
transfer to an ineligible status under Section 6.4, the cash balance then
standing to the credit of the Participant's Contribution Account shall be--

         (a) returned to the Participant, in cash, without interest, as soon as
practicable, upon the Participant's written request received by the
Administrator at least 30 days before the next Purchase Date; or

         (b) held under the Plan and used to purchase Common Stock for the
Participant under the automatic exercise provisions of Section 6.5.

         7.2 IN-SERVICE WITHDRAWALS. During such time, if any, as the
Corporation participates in a Direct Registration System, shares of Common Stock
acquired upon exercise of an Option shall be directly registered in the name of
the Participant and the Participant may withdraw certificates in accordance with
the applicable terms and conditions of such Direct Registration System. If the
Corporation does not participate in a Direct Registration System, (i) a
Participant may, while an Employee of the Corporation or any Subsidiary,
withdraw certificates for some or all of the shares of Common Stock credited to
his or her Stock Account at any time, upon 30 days' written notice to the
Administrator, and (ii) each Participant shall be permitted only one withdrawal
under this Section during each Offering Period. If a Participant requests a
distribution of only a portion of the shares of Common Stock credited to his or
her Stock Account, the Administrator will distribute the oldest securities held
in the Participant's Stock Account first, using a first in-first out
methodology.

         7.3 TERMINATION OF EMPLOYMENT FOR REASONS OTHER THAN DEATH. If a
Participant terminates employment with the Corporation and the Subsidiaries for
reasons other than death, the cash balance in the Participant's Contribution
Account shall be returned to the Participant in cash, without interest, as soon
as practicable. Certificates for the shares of Common Stock credited to his or
her Stock Account shall be distributed to the Participant as soon as
practicable, unless the Corporation then participates in a Direct Registration
System, in which case, the Participant shall be entitled to evidence of
ownership of such shares in such form as the terms and conditions of such Direct
Registration System permit.

         7.4 DEATH. In the event a Participant dies, the cash balance in his or
her Contribution Account shall be distributed to the Participant's estate, in
cash, without interest, as soon as practicable. Certificates for the shares of
Common Stock credited to the Participant's Stock Account shall be distributed to
the estate as soon as practicable, unless the Corporation then participates in a
Direct Registration System, in which case, 

                                       9
<PAGE>

the estate shall be entitled to evidence of ownership of such shares in such
form as the terms and conditions of such Direct Registration System permit.

         7.5 REGISTRATION. Whether represented in certificate form or by direct
registration pursuant to a Direct Registration System, shares of Common Stock
acquired upon exercise of an Option shall be directly registered in the name of
the Participant or, if the Participant so indicates on the Request Form, (a) in
the Participant's name jointly with a member of the Participant's family, with
the right of survivorship, (b) in the name of a custodian for the Participant
(in the event the Participant is under a legal disability to have stock issued
in the Participant's name), or (c) in a manner giving effect to the status of
such shares as community property. No other names may be included in the Common
Stock registration. The Corporation shall pay all issue or transfer taxes with
respect to the issuance or transfer of shares of such Common Stock, as well as
all fees and expenses necessarily incurred by the Corporation in connection with
such issuance or transfer.

                                  ARTICLE VIII

made, unless required by law, or

         (b) unless previously approved by the stockholders of the Corporation,
where such approval is necessary to satisfy federal securities laws, the Code,
or rules of any stock exchange on which the Corporation's Common Stock is
listed-

                  (1) in any manner materially affect the eligibility
         requirements set forth in Sections 3.1 and 3.3, or change the
         definition of Employer as set forth in Section 2.13,

                  (2) increase the number of shares of Common Stock subject to
         any options issued to Participants (except as provided in Sections 4.2

         Plan.

         8.2 TERMINATION. The Committee may terminate the Plan at any time in
its sole and absolute discretion. The Plan shall be terminated by the Committee
if at any time the number of shares of Common Stock authorized for purposes of
the Plan is not sufficient to meet all purchase requirements, except as
specified in Section 4.1.

         Upon termination of the Plan, the Administrator shall give notice
thereof to Participants and shall terminate all payroll deductions. Cash

accounts shall be promptly distributed to them; and any Common Stock
certificates issued and delivered to Participants prior to such date shall
remain the property of the Participants.

         9.2 EMPLOYMENT RIGHTS. Neither the establishment of the Plan, nor the
grant of any Options thereunder, nor the exercise thereof shall be deemed to

Subsidiary to discharge any Employee or otherwise modify the employment
relationship at any time.

         9.3 TAX WITHHOLDING. The Administrator may make appropriate provisions

     discuss in good faith the level of discount, if any, applicable to the 
     new list prices. In the event of changes in any laws or regulations of 
     any jurisdiction relating to the promotion, sale or pricing of

2.3  Shipment Replacement Requirements.

     (a) Within three (3) business days of receipt of a prescription, Nova
     Factor will undertake an initial insurance verification for each new
     patient for whom Genentech HGH has been prescribed and will attempt to
     obtain all necessary prior authorizations as required by the involved
     third party payer. In performing such verification, Nova Factor will
     obtain and provide prescribing physician letters of medical necessity
     to third party payers and attempt to obtain verification of insurance
     coverage from such third party payers. Nova Factor must compete the
     Benefits/Coverage Insurance Verification form attached as EXHIBIT C at
     the time of obtaining such verification of insurance coverage. For
     purposes of this entire SECTION 2.3, "third party payer" shall mean a
     private third party health insurance payer that does not specifically
     exclude human growth hormone or injectable drugs from coverage but
     shall not include Government Programs.

     (b) If Nova Factor is not able to verify such third party payer
     coverage or obtain prior authorization within that three (3) business
     day period, Nova Factor will provide *. Thereafter, Nova Factor may
     provide *.

     (c) For each patient who does not have third party payer coverage or
     for whom insurance coverage is in doubt, Nova Factor shall promptly
     instruct and assist that patient in efforts to gain eligibility for
     COBRA, if applicable, or Government Programs as appropriate.

     (d) If during the time of this Agreement, a third party payer denies
     authorization or payment to Nova Factor for Genentech HGH that has been
     dispensed by Nova Factor to a patient in accordance with this
     Agreement, Nova Factor will thereafter request that the third party
     payer provide the basis for that denial in writing. *

     (e) If Nova Factor determines that insurance coverage, COBRA benefits,
     or coverage under a Government Program is not available, Nova Factor
     shall promptly contact such patient to determine the patient's ability
     to pay for the Genentech's HGH with his or her individual funds, and,
     if appropriate, refer such patient to Genentech's Uninsured Patients'
     Program, with prescriptions for Genentech HGH.

     (f) Nova Factor will bill payers and patients for all Genentech HGH
     dispensed. Subject to the limitations and requirements of this SECTION
     2.3, * for the time period commencing on the first date of dispensing
     Genentech HGH following initiation of such patient's Genentech HGH
     therapy or following the date of a Coverage Interruption and ending *;
     provided, however, that in no event will Genentech provide *.

     (g) Genentech shall not *. Genentech shall not * to Nova Factor in
     accordance with the terms of this SECTION 2.3 *, which states are
     listed on EXHIBIT E as such EXHIBIT E may be updated by written notice

        audits, and Nova Factor shall cooperate fully with the persons 
        conducting the audit, including full access to the necessary 
        facilities and records at all reasonable times, and copies, at 
        Genentech's expense, of all relevant records, provided; however, that 
        Genentech's audit right shall be limited to (i) bi-annual audits or 
        (ii) such other audits as Genentech may deem necessary, in its 
        reasonable judgment, to investigate quality assurance problems that 
        constitute material trends.

Section 3.  Distribution of Genentech HGH

3.1  Dispensing Obligation. Subject to Section 4.1 of this Agreement and to 
the extent in accordance with applicable laws and regulations, Nova Factor 
shall evaluate the reimbursement status of, and dispense Genentech HGH to, 
all patients with a prescription for Genentech HGH who are referred by any 
person or entity to Nova Factor. Within three (3) business days of Nova 
Factor's receipt of each prescription or other appropriate shipment request, 
Nova Factor shall dispense Genentech HGH to patients without regard to third 
party payer coverage of such patient's Genentech HGH; provided, however, that 
if the patient or physician specifically requests a delay in dispensing or if 
prior authorization is required for a Government Program patient, both as 
documented by written records of Nova Factor, said (3) day time frame 
shall not apply, and Nova Factor shall use its commercially reasonable best 
efforts to ship the requested Genentech HGH within thirty (30) days of such 
prescription or shipment request.

3.2  Exceptions. Notwithstanding Section 3.1 above, Nova Factor shall not be 
obligated to dispense Genentech HGH to patients:

     (a) having no insurance or other third party payer coverage (or coverage 
     equal to an amount less than * percent (*%) of Nova Factor's 
     acquisition cost for Genentech HGH for such patient) for Genentech HGH 
     after a duly diligent evaluation by Nova Factor of such patient's 
     eligibility for all reasonable payer sources, including, without 
     limitation, a Government Program, or

     (b) where the patient, physician or payer repeatedly and consistently 
     refuses to assist with the reimbursement process, to complete the 
     required documentation necessary to process the reimbursement request, 
     or to process a request for coverage, as demonstrated by: (i) a failure 
     to respond to at least three (3) consecutive Nova Factor contacts, at 
     least one (1) of which is a written contact and all of which are 
     documented in Nova Factor's written records; or (ii) a failure to 
     substantially comply with the material requirements of a contract 
     between the payer and the patient or physician; or (iii) a failure by 
     the patient to pay Nova Factor within a reasonable time frame. Nova 
     Factor agrees that it shall use its commercially reasonable best efforts 
     to remedy the refusal, including, without limitation, contacting and 
     cooperating with Genentech to resolve the issue with the patients, payer 
     or provider, and exhausting all legal options under the federal, state, 
     ERISA or other applicable reimbursement standards to resolve the 
     coverage or claim request; provided, however, that the number of 
     patients denied service by Nova Factor each calendar year under this 
     Section 3.2(b) shall not exceed two percent (2%) of the total number of 
     patients with prescriptions or

     statements of medical necessity for Genentech HGH who are referred to, 
     or dispensed or serviced by, Nova Factor during such year. In the event 
     that such number of patients exceeds or threatens to exceed two percent 
     (2%) because of factors beyond the reasonable control of the Parties, 
     then the Parties shall meet to discuss methods to remedy such problems.

3.3  Notice to Genentech. Promptly (which means Nova Factor shall use its 
commercially reasonable best efforts to notify within three (3) business 
days) after Nova Factor learns that a patient either lacks or is not 
eligible for any third party payer coverage for Genentech HGH, or at least 
fifteen (15) business days prior to Nova Factor terminating or electing not 
to ship to a patient during Appeals or due to a refusal to cooperate or 
otherwise, Nova Factor shall notify Genentech of such patient and the reasons 
for such patient's non-eligibility or lack of coverage, or for Nova Factor's 
refusal to service, as the case may be, and Genentech may provide Genentech 
HGH to such patient through its Uninsured Patient's Program or in any other 
manner Genentech chooses.

3.4  Delivery Obligations. Nova Factor shall deliver Genentech HGH to the 
home of each patient or to such other delivery point as may be designated by 
the patient. Nova Factor may distribute Genentech HGH through its Affiliates 
and, with the prior written approval of Genentech, which approval may be 
withheld at Genentech's sole discretion, other third parties; provided, 
however, that Nova Factor hereby guarantees compliance by such Affiliates and 
third parties with the terms of this Agreement.

3.5  Appeals and Collections. Nova Factor shall use its commercially 
reasonable best efforts to obtain reimbursement from the patient and/or the 
third party payer or other payer, including in the event of a denial of 
insurance coverage, prosecuting all Appeals. Said Appeals shall include at 
least the following steps unless such step is not available: (a) obtaining a 
written denial of payment which sets forth the rationale for such denial; (b) 
sending a written appeal to the third party payer setting forth 
comprehensively the nature of the appeal and providing all relevant support 
for the appeal; and (c) sending a written appeal to the next higher level of 
appeal at that third party payer. As a general matter, Nova Factor will ship 
on first level Appeals, and on second level Appeals when the clinical 
information of the patient falls within reasonable medical review criteria 
for treating growth hormone inadequacy. Nova Factor is not required to ship 
on patients with pre-existing clauses, lack of coverage for injectables, or 
no Rx coverage.

3.6  Government Programs and UPP. For each patient who does not have third 
party payer coverage or for who insurance coverage is in doubt, Nova Factor 
will promptly and diligently assess that patient's eligibility for coverage 
of Genentech HGH under all appropriate Government Programs. Nova Factor shall 
use its best


                                        10

<PAGE>

efforts to inform patients about meeting, and for patients with Government 
Program coverage, maintaining eligibility and coverage by Government 
Programs. If third party payer or Government Program coverage for Genentech 
HGH is not available, Nova Factor shall promptly contact such patient to 
determine the patient's ability to pay for the Genentech HGH with his or her 
individual funds. In the event that such patient is unable to pay for the 
Genentech HGH individually, Nova Factor shall promptly advise Genentech so 
that Genentech may consider the patient for Genentech's Uninsured Patients 
Program.

3.7  Patient Assistance Program. Nova Factor shall develop and administer a 
patient assistance program in accordance with applicable law and regulations 
to assist patients financially unable to afford Genentech HGH therapy; 
provided, however, that Nova Factor shall not have any obligation related to 
patients having no third party payer coverage for Genentech HGH therapy as 
described in Section 3.2(b), which patients may be eligible for Genentech's 
Uninsured Patients Program. Nova Factor shall develop its own financial 
criteria for patients and shall review each patient's financial status on a 
case-by-case basis, all in conformance with applicable laws, rules and 
regulations.

Section 4.  Distribution Relationship

4.1  Exclusivity. In consideration of the benefits provided to Nova Factor 
under this Agreement, Nova Factor agrees for itself not to sell and shall 
cause its Affiliates not to sell during the term of this Agreement without 
Genentech's prior written consent any product (other than Genentech HGH) 
containing human growth hormone or an analog of human growth hormone, or 
whose principal effect is that of human growth hormone, whether 
naturally-occurring or manufactured by any process. Notwithstanding the 
foregoing, Nova Factor shall have the right to distribute or sell any third 
party's human growth hormone product measured in 2x5 mg unit cartons (or 
their equivalent) (a "Third Party Unit") in a volume equal to * percent 
(*%) of the combined Nova Factor and Affiliate sales volume, in 10 mg 
equivalent units of Genentech HGH, for the preceding year. This sales volume 
shall be adjusted, in a manner mutually agreed to by Genentech and Nova 
Factor, to account for current and future Affiliate sales, in 10 mg 
equivalent units of Genentech HGH, for the preceding year, payer formulary 
restrictions, and sales of competitive product for indications for which 
Genentech HGH does not have FDA approval. Said amount may be revised upward 
or downward upon mutual agreement of Genentech and Nova Factor. At the end of 
each calendar quarter, Nova Factor shall provide a statement to Genentech 
setting forth the number of Third Party Units distributed by Nova Factor and 
its Affiliates, which amount shall be subject to audit by Genentech in 
accordance with Section 2.7(a)(9). In the event that in any year, based upon 
such quarterly reports, Nova Factor and its Affiliates distribute Third Party 
Units above the * percent (*%) limit described in

the second sentence of this paragraph, Nova Factor shall pay to Genentech 85% 
of Nova Factor's average purchase price of Genentech HGH during that year for 
each Third Party Unit distributed by Nova Factor or its Affiliates during 
such year in excess of said amount. Nova Factor also agrees and shall cause 
its Affiliates not to distribute or sell Genentech HGH during the term of 
this Agreement outside of the United States or its territories or possessions 
without the prior written consent of Genentech, which consent shall be given 
or withheld in Genentech's sole discretion.

4.2  Substitution and Counter-Detailing of Human Growth Hormone Products. 
Except as may be required by applicable law, Nova Factor agrees that it shall 
not substitute, generically or therapeutically, any other human growth 
hormone product(s) for prescriptions written for Genentech HGH to patients 
covered under this Agreement, but specifically excluding patients who are 
covered under a Government Program. Nova Factor and its Affiliates shall not 
counter-detail Genentech HGH. Nova Factor and its Affiliates agree not to (1) 
promote against, counter-detail, or disparage the Genentech Single Point of 
Contact system to be administered by Genentech or its subcontractor for 
patients with prescriptions of Genentech HGH, (2) promote against, 
counter-detail, or disparage the Genentech Managed Distribution System 
operated by Healthcare Delivery Systems, Inc. and implemented by Genentech 
for the distribution of Genentech HGH through a network of pharmacies 
licensed to dispense Genentech HGH ("GMDS"), or (3) promote GMDS. Nova Factor 
may inform its customers of its status as an authorized dispensing pharmacy 
within GMDS; provided, however, that Nova Factor shall not so inform its 
customers in writing unless Genentech has previously approved, in writing, 
such written materials, which approval shall not be unreasonably withheld. 
Nova Factor and its Affiliates shall not convert or attempt to convert 
patients referred to Nova Factor as a GMDS provider to another delivery 
option. Nova Factor agrees that it shall make no representation, guarantee or 
warranty about Genentech HGH, whether in writing or orally, except as is 
contained in written materials delivered to Nova Factor by Genentech for use 
in promoting and selling Genentech HGH or as may otherwise be agreed to by 
Genentech in writing. Genentech shall have the right to approve Nova Factor 
promotional materials which contain pertinent facts relative to Genentech HGH 
and all such materials shall comply with applicable regulatory requirements 
and shall not contain misrepresentations, either about Genentech HGH or a 
competitive product, or disparage a competitive product.

Section 5.  Term; Termination

5.1  Term. The term of this Agreement shall commence as of the Effective Date 
and continue through December 31, 1999, unless extended by mutual agreement 
of the Parties for additional one-year periods.


                                       12

<PAGE>

5.2  Termination Events. The foregoing notwithstanding, this Agreement may be 
terminated by a Party: (a) upon any material breach of this Agreement by the 
other Party which breach is not cured within sixty (60) days of notice by the 
non-breaching Party; or (b) immediately upon giving notice (i) upon the 
institution by or against the other Party of insolvency, receivership or 
bankruptcy proceedings or any other proceedings for the settlement of the 
other Party's debts, (ii) upon the other Party's making an assignment for the 
benefit of its creditors, or (iii) upon the other Party's dissolution. This 
Agreement may also be terminated upon mutual agreement of the Parties hereto.

5.3  Effect of Termination. Upon termination, if requested by Genentech, Nova 
Factor shall return all unused Genentech HGH to Genentech and shall be 
reimbursed by Genentech for the reasonable shipping expenses of the return 
and the purchase price of the Genentech HGH returned if the purchase price 
was previously paid by Nova Factor. If Genentech does not request such unused 
Genentech HGH to be returned, Nova Factor may sell such unused Genentech HGH 
to patients or return it to Genentech for credit. Nova Factor shall also 
return, if so requested by Genentech, all sales aids and other associated 
material supplied to Nova Factor by Genentech. Termination shall not relieve 
either Party of obligations incurred prior to termination, including Nova 
Factor's obligation to pay for Genentech HGH ordered by and delivered to it 
under this Agreement, provided that Genentech has not requested return of 
that Genentech HGH, and Genentech's obligations of reimbursements accrued as 
of the termination date under the programs described in Section 2 above, 
which obligations of reimbursement shall first be set off against obligations 
of Nova Factor to Genentech, and if any reimbursement credits remain after 
set-off after a reasonable period for reconciliation of all outstanding 
claims, shall be paid in cash. The provisions of Sections 6.6 and 6.14 shall 
survive any termination of this Agreement.

5.4  Change In Control. If Nova Factor or any of its Affiliates or all or 
substantially all of either of their assets are to be acquired by whatever 
means, including merger with or into, another entity, including an Affiliate 
(the "Acquiring Entity") Nova Factor shall so notify Genentech in writing at 
least ninety (90) days prior to the date of occurrence of such event, and 
Genentech shall have the right to terminate this Agreement at any time until 
ninety (90) days after Genentech's receipt of written notice from Nova

terminates this Agreement, Nova Factor agrees for itself, its Affiliates and 
for any such entity that, without Genentech's prior written consent, neither 
it nor the Acquiring Entity nor any party affiliated with either of them 
shall sell to any patient receiving Genentech HGH at the time of said

Inventory during each calendar quarter; provided that, Nova Factor agrees 
that at the option of Genzyme it will purchase adequate amounts of 
Cerezyme-TM- to bring the Combined Inventory to a *-day level prior to the 
end of any such calendar quarter, however, in no event will such purchase 
cause the inventory to exceed an average of * days for such calendar 
quarter; provided further that in no event shall Nova Factor be required to 
have on hand Combined Inventory in excess of * dollars.  The 
calculation of inventory will be based upon the average of the unit sales 
volume for the previous month, the projected unit sales volume for the 
current month, and the projected sales volume for the next month as described

its replacement (i.e., market) value against fire, theft, loss or 
destruction, and such other risks as are customarily insured against by 
prudent persons in a similar line of business, with an insurance carrier

permit Nova factor to file claims with a third party payor, if any, or to 
submit invoices to the appropriate Cerezyme-TM- Customer.

     3.6  Distribution and Pharmacy Services.

single or multiple doses, but only if such does(s) are to be administered to 
an Approved Patient(s).  Nova Factor shall not provide Cerezyme-TM- to any 
Cerezyme-TM- Customer without the prior authorization of Genzyme.

          (c)  Pharmacy Records.  Nova Factor shall maintain such pharmacy 
records as are required by applicable federal and state laws, regulations and

or other similar method of shipment selected by Nova Factor.

          (d)  Return of Cerezyme-TM-.  In the event that a shipment of 
Cerezyme-TM- is refused or rejected by the Cerezyme-TM- Customer, Nova Factor 
will cause the shipment of Cerezyme-TM- to be returned to the Warehouse at

                     (i)   Nova Factor shall assume responsibility for and 
         shall indemnify and hold Genzyme harmless and defend Genzyme from 
         all losses (including claims for injuries to employees of Nova

         of Nova Factor, its agents or employees; or (C) any 
         misrepresentation or breach of any representation or warranty made 
         herein by Nova Factor; provided, however, that Nova Factor shall 
         have no liability to Genzyme for loss of profits to Genzyme in the 
         event Nova Factor is unable, through no fault of Nova Factor's, to 
         ship Cerezyme-TM- to a Cerezyme-TM- Customer; and

                     (ii)  Genzyme shall assume responsibility for and shall 
         indemnify and hold Nova Factor harmless and defend Nova Factor from 
         all losses (including claims for injuries to employees of Nova

         this Agreement; (B) the negligent acts or omissions or wrongful acts
         of Genzyme, its agents or employees; (C) any misrepresentation or

                                       20
<PAGE>

other party. In the event of such cancellation, termination, reduction or 
change of the coverage described herein, the party maintaining such insurance 
shall immediately obtain substitute or replacement coverage. Failure to

termination of this Agreement.

         4.2   Term, Renewal and Termination.

               (a)   Initial Term. Unless otherwise terminated pursuant to 
subsection (c) below, this Agreement shall be for an initial term expiring on 
December 31, 1995 (the "Initial Term").

               (b)   Renewal. Unless otherwise terminated pursuant to 
subsection (c) below, this Agreement will automatically renew at the 
expiration of the Initial Term for an additional period of one year and shall 
thereafter automatically renew from year to year for additional one-year 
periods, unless either party shall give written notice of cancellation to the 
other party at least 90 days prior to the end of the Initial Term or the 
expiration of any extension.

               (c)   Termination. This Agreement shall automatically 
terminate (i) upon the mutual agreement of the parties, (ii) at any time upon
sixty (60) days prior notice by either party hereto, (iii) upon the insolvency 
or bankruptcy of either party, the making by either party of an assignment 
for the benefit of creditors, the consent by either party to the appointment 
of a trustee or receiver, or the appointment without its consent, of a 
trustee or receiver for it or for a substantial part of its property, or (iv) 
upon the institution by or against either party of bankruptcy, 
reorganization, arrangement or insolvency proceedings. In addition, if either 
party hereto shall breach the terms of this Agreement, the nonbreaching party

Agreement shall at the option of the nonbreaching party be terminated

                                       21
<PAGE>

immediately upon the conclusion of such 30 day period. Late payment by Nova 
Factor under the terms of Section 3.2(c) hereof shall not constitute a breach 
of the terms of this Agreement sufficient to give rise to termination of this 
Agreement.

               (d)   Return of Cerezyme-TM-. In the event of termination of 
this Agreement, Nova Factor shall cause the inventory of Cerezyme-TM- then in

for the amount due from Nova Factor for that unit, except any units which are 
destroyed or damaged for which Nova Factor shall bear the risk of loss in 
accordance with Section 3.3(d) hereof. The services fees earned by Nova 
Factor for any Cerezyme-TM- returned to Genzyme pursuant to this Section 
4.2(c) shall be offset against such credit. To the extent the amount credited 
to Nova Factor pursuant to this paragraph exceeds the amount owed by Nova 
Factor to Genzyme at such time, such excess shall be promptly paid by Genzyme 
to Nova Factor.

               (e)   Survival of Obligations. Termination of this Agreement 
shall not relieve either party from any liability or obligation it had 
incurred prior to the date of such termination including, but not limited to, 
obligations to pay any outstanding unpaid amounts due pursuant to this 
Agreement and to accept returns of Cerezyme-TM- in accordance with the 
provisions of this Agreement. It is the express intention and agreement of 
the parties hereto that all the covenants, agreements, warranties and 
indemnities contained in Sections 4.1, 4.5 and 4.7 shall survive the 
termination of this Agreement.

         4.3   Force Majeure. Neither party shall be liable to the other for 
failure or delay in the performance of any of its obligations under this 
Agreement for the time, and to the extent, such failure or delay is caused by 
riots, civil commotion, wars, hostilities between nations, embargoes, acts of 
God, earthquakes, storms, fires, strikes, sabotage, explosions, shortages of 
raw materials or power, or

                                       22
<PAGE>

any other matter which is beyond the reasonable efforts of the party to 
control. This provision shall not excuse, or apply to, obligations of a party

<PAGE>

violate the restrictions st out in Section 4.5 hereof, or interfere with the 
performance of Nova Factor's obligations hereunder.

          4.9  Records. To the extent required by Section 1861(b)(1)(I) of 
the Social Security Act, Nova Factor shall, upon proper request, allow the

and for an additional period of four (4) years following the last date 
services are furnished under this Agreement.

         4.10  Specific Performance. The parties acknowledge that violation 
of Sections 4.5 and 4.7 hereof could cause irreparable damage to the party 
against whom the violation is committed which would not adequately be 
remedied by an action at law for damages. The parties agree that, in the 
event of a breach or threatened breach of either of these sections, the party 
alleging such breach shall be entitled to injunctive relief prohibiting such 
breach or threatened breach in any court of the United States or of any 
state or other political subdivision thereof.

under other agreements and as provided by law. Nothing contained herein shall 
preclude a party from seeking equitable relief, where appropriate.

all or substantially all of the assets of

limited period of time, it may be necessary for Nova Factor to arrange for 
the performance of certain of its obligations under this Agreement by a third 
party pursuant to an agreement between Nova Factor and such third party. Nova 
Factor shall not enter into such agreement without the prior written consent 
of Genzyme, which shall not be unreasonably withheld, provided that Nova 
Factor may enter into such an agreement with PharmaThera, Inc. without the 
consent of Genzyme.

         4.13  Applicable Law. This Agreement shall be construed in 
accordance with the laws of the State of Tennessee (excluding the choice of 
law rules thereof), and the laws of the State of Tennessee shall govern the 
rights, duties, liabilities and responsibilities created hereunder.

         4.14  Headings. All headings used herein are for ease of reference 
only and shall in no way be construed as interpreting, decreasing or 
enlarging the provisions of this Agreement.

         4.15  Effect. Subject to any provisions hereof restricting 
assignment, this Agreement shall be binding upon and shall inure to the 
benefit of the parties hereto, their successors, administrators, trustees and 
permitted assigns.

constitute the entire agreement and understanding between the parties hereto 
in respect to the transactions contemplated herein and supersede all prior 
written or oral agreements, arrangements and understanding relating to the

                             SECURITY AGREEMENT



     THIS SECURITY AGREEMENT (the "Security Agreement") is made as of the 30th 
day of September, 1994 by and between NOVA FACTOR, INC., a Tennessee 
corporation ("Nova Factor") and GENZYME CORPORATION, a Delaware corporation 
("Secured Party").


                                  RECITALS:


     WHEREAS, Nova Factor and Secured Party have entered into a certain 
Distribution Agreement dated the date hereof (the "Distribution Agreement") 
pursuant to which Secured Party has agreed to sell to Nova Factor and Nova 
Factor has agreed to purchase from Secured Party quantities of the 
prescription drug known as Cerezyme-TM- on the terms and conditions set forth 
therein; and

     WHEREAS, in order to secure (i) the amounts payable to Secured Party 
under Section 3.2(c)of the Distribution Agreement, (ii) the fulfillment of 
the other obligations of Nova Factor under the Distribution Agreement and 
(iii) the fulfillment of the obligations of Nova Factor hereunder 
(collectively, the "Secured Obligations"), Nova Factor is required to enter 
into this Security Agreement and to grant to Secured Party a security 
interest in the Collateral (as hereinafter defined).

     NOW, THEREFORE, in consideration of the foregoing and of the mutual 
covenants and agreements herein contained, the parties hereto hereby agree as 
follows:

     1.   SECURITY INTEREST.

     1.1  COLLATERAL. As security for the Secured Obligations, Nova Factor 
hereby grants to Secured Party a security interest in and lien on, and 
assigns and pledges to Secured Party, all of the following (the "Collateral"):

          (a) all Cerezyme-TM- sold by Secured Party to Nova Factor from time 
to time pursuant to Article III of the Distribution Agreement, which 
Cerezyme-TM- shall be held for sale by Nova Factor to third parties in 
accordance with the terms of the Distribution Agreement (the "Inventory");

<PAGE>


          (b) all accounts, chattel paper, instruments and general 
intangibles (as such terms are defined in Article 9 of the Uniform Commercial 
Code as in effect from time to time in the State of Tennessee), accounts 
receivable and other obligations of any kind, whether or not evidenced by an 
instrument or chattel paper (collectively, the "Accounts") of Nova Factor 
representing or arising from the sale of Cerezyme-TM- by Nova Factor from the 
Inventory; and

          (c) any and all additions to any of the foregoing, and any and all 
replacements, products and proceeds (including insurance proceeds) of any of 
the foregoing.

     1.2  RIGHT OF SECURED PARTY TO PAY TAXES OR COSTS RELATING TO 
COLLATERAL. Secured Party shall have the right, but not the obligation, to 
pay any taxes or levies on the Collateral or any costs to preserve the 
Collateral, which payment shall constitute a part of the Secured Obligations; 
provided, however, that no taxes payable by Secured Party pursuant to the 
Distribution Agreement shall be deemed part of the Secured Obligations.

     1.3  FINANCING STATEMENTS. At the request of Secured Party, Nova Factor 
will promptly join with Secured Party in executing financial statements, 
continuation statements, assignments, certificates and other documents with 
respect to the Collateral pursuant to the Uniform Commercial Code and 
otherwise as may be necessary to enable Secured Party to perfect or from time 
to time continue the security interests granted hereby, including without 
limitation such financing statements, continuation statements, certificates 
and other documents as may be necessary to perfect a security interest in any 
Cerezyme-TM- acquired by Nova Factor subsequent to the date hereof pursuant 
to the terms of the Distribution Agreement or in any replacements or proceeds 
thereof, in form satisfactory to Secured Party, and Secured Party will pay 
the cost of filing the same in all public offices wherever Secured Party 
deems filing to be necessary or desirable. Nova Factor grants Secured Party 
the right, at Secured Party's option, to file any or all such financing 
statements, continuation statements and other documents pursuant to the 
Uniform Commercial Code and otherwise, without Nova Factor's signature, and 
irrevocably appoints Secured Party as Nova Factor's attorney in fact to 
execute any such statements and documents in Nova Factor's name and to 
perform all other acts which Secured Party reasonably deems appropriate to 
perfect and continue the security interests conferred by this Security 
Agreement.

     1.4  INJURY TO COLLATERAL: STORAGE OF INVENTORY. No injury to, or loss or 
destruction of, the Collateral shall relieve Nova Factor of any of the 
Secured Obligations. Nova Factor shall handle and store the Inventory in the 
manner required by the Distribution Agreement except as otherwise provided 
herein.


                                   -2-

     1.5  COLLECTING AND SERVICING ACCOUNTS. Nova Factor is authorized to 
collect and service the Accounts, provided that Secured Party may, without 
cause or notice, upon the default of Nova Factor hereunder, terminate such 
authority at any time.

     1.6  NOTICE OF PAST DUE ACCOUNTS. Nova Factor will promptly notify 
Secured Party if any Account owned by it in excess of Fifty Thousand Dollars 
($50,000) is not paid within one hundred and twenty (120) days after the 
date of shipment by Nova Factor of the Inventory to which such Account 
relates, or if an Account debtor thereof disputes liability, exercises a right 
of set-off or counterclaim, becomes insolvent, fails, or goes out of business.

     2.   REPRESENTATIONS, WARRANTIES, AGREEMENTS AND COVENANTS OF NOVA 
FACTOR. Nova Factor represents, warrants, agrees and covenants that:

     2.1  Unless Secured Party shall otherwise agree in writing, Nova Factor 
will not grant or permit to exist, nor shall there exist, any security 
interest in, or any lien, attachment, levy or encumbrance upon, any of the 
Collateral, except for the security interest granted to Secured Party 
hereunder and except for any encumbrance (as hereafter defined) in existence 
at the time Nova Factor acquired or acquires the Collateral that has been 
subordinated to the lien created by this Security Agreement and has been 
approved, in writing by Secured Party, or, subject to the approval of Secured 
Party, which shall not be unreasonably withheld, any lien credited subsequent 
to the date hereof that is subordinate to the lien of Secured Party. Nova 
Factor has not signed or filed or authorized the signing or filing of, a 
financing statement (other than one naming Secured Party as the secured 
party) under the Uniform Commercial Code of any jurisdiction with respect to 
the Collateral or any portion thereof, except for financing statements naming 
First Tennessee Bank National Association as secured party, if agreed to in 
writing by Secured Party. For the purposes of this Section 2, "encumbrance" 
shall mean any mortgage, deed of trust, pledge, security interest, 
hypothecation, assignment, assigned deposit, arrangement, encroachment, 
claim, option, reservation, right of way, easement, covenant, lease, purchase 
right, condition, restriction, charge or defect of any kind, or any 
preference, priority or security agreement or other preferential arrangement 
of any kind or nature whatsoever (including, without limitation, any 
conditional sale or title retention agreement, any capitalized lease 
obligation having substantially the same economic effect as any of the 
foregoing, and the filing of any financing statement under the Uniform 
Commercial Code or comparable law of any jurisdiction).

     2.2  Nova Factor is a corporation duly organized, validly existing and 
in good standing under the laws of the State of Tennessee and has the full 
and unrestricted power and authority to enter into and perform the terms of 
this Security Agreement and the transactions contemplated hereby. The 
execution,


                                 -3-

<PAGE>

delivery and performance of this Security Agreement have been duly authorized 
by all necessary corporate action of Nova Factor and this Security Agreement 
has been duly executed on behalf of Nova Factor.

     2.3  This Security Agreement constitutes a legal, valid and binding 
obligation of Nova Factor, enforceable against Nova Factor in accordance with 
its terms, except to the extent enforceability may be limited by bankruptcy, 
insolvency or other similar laws affecting the rights of creditors generally. 
The execution, delivery, and performance of this Security Agreement and of 
all other instruments or agreements executed in connection herewith will not 
(i) violate, conflict with, or constitute a default under any law, 
regulation, order or any other requirement of any governmental authority or 
arbitrator, any terms of the Articles or Certificate of Incorporation or 
bylaws of Nova Factor, or any contract, agreement or other arrangement 
binding upon or affecting Nova Factor or any of its properties, (ii) result 
in the creation, imposition or acceleration of any indebtedness of any nature 
upon, or with respect to, Nova Factor or any of its properties, (iii) have a 
material adverse effect on the conduct of Nova Factor's business as it is now 
being conducted and as proposed to be conducted while this Security Agreement 
is in effect, or (iv) otherwise impair the value of the security interests 
granted to Secured Party hereunder.

     2.4 Nova Factor will (i) execute and deliver any and all documents, or 
cause the execution and delivery of any and all documents, reasonably 
necessary for Secured Party to create, perfect, preserve, validate or 
otherwise protect its security interest in the Collateral; (ii) maintain, or 
cause to be maintained, at all times, Secured Party's security interest in 
the Collateral; (iii) after the occurrence of an Event of Default hereunder, 
immediately upon learning thereof, report to Secured Party any reclamation, 
return or repossession of any of their Inventory, any claim or dispute 
asserted by any debtor or other obligor of Nova Factor, and any other matters 
affecting the value or enforceability or collectibility of any of the 
Collateral; (iv) after the occurrence of an Event of Default hereunder, 
defend the Collateral against all claims and demands of all persons at any 
time claiming the same or any interest therein adverse to Secured Party and 
pay all costs and expenses (including attorneys' fees and expenses) incurred 
in connection with such defense; and (v) at Nova Factor's sole cost and 
expense (including attorneys' fees and expenses), settle any and all such 
claims and disputes referenced in paragraph 2.4(iv) above and indemnify and 
protect Secured Party against any liability, loss or expense arising 
therefrom or out of any such reclamation, return (except as otherwise 
provided in Section 3.7(d) of the Distribution Agreement) or repossession of 
any of the Collateral; provided, however, if Secured Party shall so elect, it 
shall have the right following the occurrence of an Event of Default 
hereunder to settle, compromise, adjust, or litigate all claims or disputes 
directly with the debtor or other obligor of Nova Factor upon such reasonable 
terms and conditions as Secured Party deems advisable, and to charge all 
costs and expenses thereof (including

                                     -4-


<PAGE>

attorneys' fees and expenses) to Nova Factor's account and to add them to the 
Secured Obligations.

     2.5 Nova Factor's principal place of business and its chief executive 
office are located at the address for Nova Factor set forth in Section 10 
hereof, and Nova Factor shall not change such location unless Nova Factor 
shall have provided to Secured Party at least (30) days' prior notice of any 
changes in the location of Nova Factor's principal place of business and Nova 
Factor's chief executive office. Notwithstanding anything in the Distribution 
Agreement to the contrary, the Inventory shall be located at Nova Factor's 
warehouse in Memphis, Tennessee and the records and books of account relating 
to the Collateral shall be located at Nova Factor's chief executive office, 
and Nova Factor shall not change such locations unless with the prior written 
consent of Secured Party given no less than thirty (30) days in advance of 
any relocation of the Inventory or the books and records.

     2.6 Nova Factor will (i) promptly notify Secured Party in writing of any 
compromise, settlement or adjustment with respect to an Account; (ii) 
maintain accurate and complete records of the Accounts and make the same 
available to Secured Party at reasonable times during normal business hours 
after receipt of notice from Secured Party, except after the occurrence of an 
Event of Default in which case no notice shall be required; (iii) if 
requested by Secured Party and desirable for the protection of Secured 
Party's interest in the Collateral, stamp, in form and manner satisfactory to 
Secured Party, its accounts receivable ledger and other books and records 
pertaining to the Accounts, with an appropriate reference to the security 
interest of Secured Party in the Accounts; (iv) upon Secured Party's 
reasonable request, furnish Secured Party original or other papers relating 
to the sale of Cerazyme-TM- which created any Account; and (v) promptly 
notify Secured Party in writing of the return or rejection of any 
Cerezyme-TM- represented by the Accounts.

      2.7 For any transaction governed by Article II of the Distribution 
Agreement, from time to time as Secured Party may require, Nova Factor will 
deliver to Secured Party schedules of all outstanding Accounts as Secured 
Party may reasonably request. Such schedules shall be in form satisfactory to 
Secured Party and shall show the age of such Accounts in intervals of not more 
than 30 days, and contain such other information and be accompanied by such 
reasonably supporting documents as Secured Party may from time to time 
reasonably prescribe. Nova Factor shall also deliver to Secured Party copies 
of Nova Factor's invoices, evidences of shipment or delivery and such other 
schedules and information as Secured Party may reasonably request. For any 
transaction governed by Article III of the Distribution Agreement, Nova 
Factor shall prepare, maintain and deliver the records and books and other 
materials in the manner provided in Section 3.11 of the Distribution 
Agreement. The items to be provided

                                      -5-
<PAGE>

under this Section are to be prepared and delivered to Secured Party from 
time to time solely for its convenience in maintaining records of the 
Collateral and Nova Factor's failure to give any of such items to Secured 
Party shall not affect, terminate, modify or otherwise limit Secured Party's 
security interest granted herein.

     2.8 Nova Factor will (i) sell or dispose of the Inventory only in 
accordance with the terms of the Distribution Agreement or otherwise in the 
ordinary course of business; and (ii) immediately notify Secured Party at 
least thirty (30) days prior to any change in location of any of the 
Inventory other than in the event of sales to third parties in accordance 
with the Distribution Agreement or in the ordinary course of business and, 
prior to any such change, execute and deliver to Secured Party such financing 
statements satisfactory to Secured Party as Secured Party may request.

     2.9 [Reserved]

     2.10 Except to the extent Section 3.3(d) of the Distribution Agreement 
applies, Nova Factor shall insure all of the Inventory for its replacement 
(i.e., market) value against fire, theft, loss or destruction, and such other 
risks as are customarily insured against by prudent persons in a similar line 
of business, with an insurance carrier qualified to do business in the State 
of Tennessee (or such other place as Secured Party shall authorize). Nova 
Factor shall provide Secured Party with certificates of such insurance upon 
request.

     3. EVENTS OF DEFAULT. The occurrence of one or more of the following 
events shall constitute an Event of Default hereunder (each, an "Event of 
Default"):

     condition, covenant or agreement contained in this Security Agreement or 
     in the Distribution Agreement and the continuance of such failure for 
     thirty (30) days after the receipt of written notice thereof in the case 
     of such failure. Late payment by Nova Factor to Secured Party under the 
     terms of Section 3.2(c) of the Distribution Agreement shall not 
     constitute an Event of Default but shall cause the late payment charges 
     to come into effect;

          (ii) The breach of any representation, warranty, covenant or 
     agreement by Nova Factor made in Section 2 hereof and continuance of 
     such breach for thirty (30) days after the receipt of written notice

expressly waived by Nova Factor, anything contained herein to the contrary 
notwithstanding; and (b) to exercise any one or more of the rights and 
remedies exercisable by a secured party under the Code (subject to any rights 
of Nova Factor to redeem the Collateral provided therein) or under any other 
applicable law. Upon the occurrence of any Event of Default, and without 
limiting the generality of the foregoing, Secured Party shall have the right 
to sell the Collateral at public or private sale. All reasonable attorneys' 
fees and disbursements and all other costs, charges, premiums and other 
expenses incurred in connection with any such sale shall be charged against 
and deducted from the proceeds thereof, with the balance, if any, applied in 
reduction of the Secured Obligations of Nova Factor to Secured Party, and in 
the event there is a deficiency, said deficiency shall be payable forthwith 
by Nova Factor to Secured Party (except as otherwise provided in Section 3.2 
of the Distribution Agreement). Notice of public or private sale, if given, 
shall be sufficiently given for all purposes if published once in any 
newspaper of general circulation distributed in the City of Memphis, 
Tennessee, not less than ten days prior to sale. It is agreed that ten days' 
written notice of any such sale to Nova Factor or any other person shall be 
sufficient for all purposes and is commercially reasonable. Secured Party may 
itself purchase the whole, or any part of the Collateral or any interest 
therein, free from any right of redemption on the part of Nova Factor, which 
right of redemption on the part of Nova Factor is hereby waived and released, 
but only to the extent such waiver and release is permitted by applicable law.

     Secured Party shall not be liable for failure to collect or demand 
payment of, or to protest, or give notice of nonpayment of, the Collateral or 
any part thereof, or for any delay in so doing, nor shall Secured Party be 
under any obligation to foreclose on or sell any Collateral or to take any 
other action whatsoever in regard to the Collateral or any part thereof, 
except that Secured Party hereby agrees to credit against the outstanding 
aggregate invoice price of all Inventory an amount equal to the outstanding 
aggregate invoice price of all properly stored Inventory which is returned by 
Nova Factor to Secured Party in original, sealed packaging and having not 
less than thirty (30) days remaining shelf life.

     5. TRANSFER OF COLLATERAL. Nova Factor shall not sell, lease, transfer, 
assign, mortgage, pledge or otherwise dispose of all or any portion of the

                                      -8-
<PAGE>

Collateral except in accordance with the Distribution Agreement or when 
authorized by the Secured Party in writing.


     6. RELEASE OF COLLATERAL. Promptly following payment in full or 
satisfaction of the Secured Obligations, the security interest created 
hereby shall terminate, and Secured Party shall execute and deliver such 
documents as are necessary to release Secured Party's security interest in 
the Collateral, whether such security interest was created hereby or 
otherwise; it being the intention of the parties hereto that, upon payment in 
full or satisfaction of the Secured Obligations, Nova Factor shall hold the 
Collateral free and clear of all liens, claims, charges, security interests, 
mortgages or encumbrances of Secured Party or any assignee or subrogee of 
Secured Party.

     7. BENEFIT; GOVERNING LAW. This Security Agreement shall benefit and 
bind the successors, and permitted assigns of the parties hereto, and shall 
be governed by and construed in accordance with the laws of the State of 
Tennessee (but not including the choice-of-law rules thereof).


     8. WAIVER. No delay or failure on the part of any party hereto in 
exercising any right, power or privilege under this Security Agreement or 
under any other instruments given in connection with or pursuant to this 
Security Agreement shall impair any such right, power or privilege or be 
construed as a waiver or default or any acquiescence therein. No waiver 
shall be valid against any party hereto unless make in writing and signed by 
the party against whom enforcement of such waiver is sought and then only to 
the extent expressly specified therein.

     9. ASSIGNMENT. Nova Factor shall not assign this Security Agreement, in 
whole or in part, whether by operation of law or otherwise, without the prior 
written consent of Secured Party.

    10. NOTICES. All notices, demands, requests, or other communications 
which may be or are required to be given, served, or sent by any party to any

2.   APPOINTMENT AS PREFERRED DISTRIBUTOR

2.1  Subject to the terms and conditions contained in this Agreement, Biogen 
     hereby appoints Nova Factor and Nova Factor hereby accepts appointment 
     as a nonexclusive, preferred distributor of Product to Home Delivery
     Customers. Nova Factor shall not sell Product other than to Home Delivery
     Customers without the prior written consent of Biogen. Biogen expressly
     reserves the right to appoint other distributors, to sell Product to 
     wholesalers, pharmacy benefit managers and other third parties and to 
     sell Product directly. Biogen shall provide Nova Factor with written 
     notice at least thirty (30) days prior to the effective date of any 
     agreement between Biogen and a third party under which Biogen grants the 
     third party the right to sell Product to Home Delivery Customers which 
     such notice shall specify the name of the third party.

3.   ORDERS, DELIVERY, FORECASTS

3.1  The parties hereto agree that, commencing upon Commercial Launch and 
     continuing during the term of this Agreement, Nova Factor shall purchase 
     Product from Biogen at the prices set forth in Section 8, and, subject 
     to the right of Biogen to allocate supplies of Product under Section 3.6,
     Biogen shall supply Product to Nova Factor, for sale and distribution to
     Home Delivery Customers. Nova Factor shall order Product from Biogen in 
     such quantities as are necessary to meet the demand for Product from 
     Nova Factor's Home Delivery Customers. On average during any month, Nova 
     Factor shall submit orders not more frequently than once per week. All 
     orders shall be firm and Nova Factor shall not change or cancel an order 
     without prior approval from Biogen. All purchases of Product by Nova 
     Factor shall be on the terms and conditions set forth in this Agreement.
     No purchase order, invoice or other form shall be deemed to vary the 
     terms of this Agreement. To assist Biogen in managing its manufacturing 
     operations, Nova Factor shall furnish to Biogen, on the first day of each
     month, a nonbinding forecast of Nova Factor's anticipated needs for 
     Product for such month and the following five months. Biogen shall assist
     Nova Factor in preparing forecasts for the first three months after 
     Commercial Launch. Each forecast shall represent Nova Factor's good faith
     best estimate of its Product needs. Notwithstanding anything herein to 
     the contrary, if Biogen receives an order in any month which would cause 
     the total amount ordered for such month to exceed the amount shown on 
     the first forecast for such month, Biogen shall have the right, in its 
     sole discretion, to reject the order. As soon as Nova Factor's inventory
     falls to a one-week supply of Product, Nova Factor shall submit an order 
     to Biogen for an additional two (2) weeks' supply of Product, based on 
     Nova Factor's most recent forecast. Biogen shall notify Nova Factor of 
     receipt from the FDA of approval to manufacture Product at Biogen's 
     Cambridge facility and of approval to market and sell Product in the 
     Territory and of the date of Commercial Launch.

3.2  Biogen shall ship Product to Nova Factor not more frequently than weekly 
     FOB Biogen's warehouse facility. Biogen shall ship Product to Nova 
     Factor by means of transportation




                                       3



<PAGE>


     (commercial truck or better) determined by Biogen and at Biogen's cost. 
     While Biogen shall use reasonable efforts to avoid any delay in 
     delivering Product on the delivery dates agreed upon by the parties, 
     failure to deliver Product by the agreed upon date will not be sufficient
     cause for termination of this Agreement by Nova Factor as long as the 
     delay does not extend beyond two (2) weeks from the agreed upon delivery
     date, nor will Biogen be liable to Nova Factor for late delivery.

3.3  Nova Factor shall unload each shipment of Product immediately upon 
     receipt from Biogen in accordance with the applicable SOP. The parties 
     acknowledge that preparation of the SOPs will continue after execution 
     of this Agreement and Biogen and Nova Factor shall each use reasonable 
     efforts and shall each cooperate with the other to develop a set of 
     mutually agreeable SOPs within three (3) months after execution of this 
     Agreement. Nova Factor shall store Product in a refrigerated storage 
     area at the Facility. Nova Factor shall notify Biogen prior to moving 
     Product to another location for storage and distribution. Nova Factor 
     shall use storage facilities and storage conditions for Product which 
     comply with applicable SOPs. Nova Factor shall at all times handle and 
     store Product in accordance with applicable SOPs. Nova Factor shall not 
     alter Product packaging without Biogen's consent (except to remove 
     Product from the shipping containers) and shall not alter Product 
     labeling except to add a prescription label to Product. Nova Factor 
     shall at all times comply with the information and recommendations 
     communicated by Biogen in writing with respect to the storage, handling 
     and shipment of Products, provided that if such information and 
     recommendations are materially different than those included in the SOPs 
     or otherwise set forth in this Agreement and result in a material 
     increase in the costs incurred by Nova Factor in performing its 
     obligations under this Agreement, the parties shall negotiate in good 
     faith *. Nova Factor shall be responsible for all costs associated with 
     storage, handling and shipment from the Facility of Product.

3.4  Nova Factor shall carefully examine Products upon delivery and shall 
     notify Biogen within one (1) business day of any nondelivery of a 
     portion of a shipment or any defect in any Product which is reasonably 
     discoverable upon visual inspection of the Product without unloading 
     individual shipping units. Along with notice of any defect, Nova Factor 
     shall furnish to Biogen a detailed description of the nature of the 
     defect. Upon receipt of notice of any defect or nondelivery, Biogen, at 
     its option, shall replace or repair any defective Product or issue Nova 
     Factor a credit in the amount of the purchase price paid for any 
     defective Product or replace or issue Nova Factor a credit in the amount 
     of purchase price paid for any undelivered Product. Except as set forth 
     in Section 16, the preceding sentence sets forth Biogen's sole liability 
     with respect to Product defects reasonably discoverable upon visual 
     inspection of the Product without unloading individual shipping units or 
     with respect to Product that is not in accordance with Nova Factor's 
     order and Section 9.1 sets forth Biogen's sole liability with respect to 
     other Product defects and Biogen shall not be otherwise liable to Nova 
     Factor. In the absence of written notice from Nova Factor to Biogen in 
     accordance with the terms of this Section 3.4, a shipment of Products 
     shall be deemed to have been delivered and accepted by Nova

* Omitted information is the subject of a request for confidential treatment 
  pursuant to Rule 406 under the Securities Act of 1933 and has been filed 
  separately with the Securities Exchange Commission.

     Factor as complete and in satisfactory condition. Nova Factor shall, at 
     Biogen's request and expense, follow Biogen's instructions to return to 
     Biogen or Biogen's third party disposal company any Products delivered 
     to Nova Factor which are not in compliance with the Specifications. Nova 
     Factor shall cooperate with Biogen in investigating the cause of any 
     defect in Product.

3.5  Title to Product shall transfer to Nova Factor upon delivery of Product 
     to the carrier for shipment to the Facility. Risk of loss of Product 
     shall transfer to Nova Factor upon delivery of Product to the Facility.

3.6  Notwithstanding anything herein to the contrary, in the event of a 
     shortage of Product, Biogen reserves the right to allocate available 
     supplies of Product in its sole discretion. If Biogen is not able to 
     supply Product to Nova Factor in the quantities ordered by Nova Factor 
     for more than twelve (12) weeks on any occasion during the term of this 
     Agreement because of a Product shortage, Nova Factor shall have the right
     to terminate this Agreement for material breach under Section 14.3 
     excluding the thirty (30) day cure period.

4.   CUSTOMER ORDERS AND HOME DELIVERY

4.1  Marketing and sales literature distributed by Biogen's sales force will 
     contain a Biogen toll-free number as the point of contact for all
     potential customers for Product. Biogen's customer service 
     representatives shall include Nova Factor in their description to 
     potential customers of various purchase and delivery options for 
     Product, and, if a potential customer expresses interest in Nova 
     Factor's home delivery program, the Biogen customer service 
     representative shall forward the call or direct the customer to Nova 
     Factor. Biogen and Nova Factor shall mutually agree on the description 
     of Nova Factor to be used by Biogen's customer service representatives. 
     Biogen shall provide Nova Factor with a copy of the script used by 
     Biogen's customer service representatives in describing Product 
     distribution options to potential customers. Nova Factor shall maintain 
     a telephone line dedicated to calls transferred from Biogen and to calls 
     from customers for Product. Nova Factor shall answer all calls from 
     customers for Product in accordance with a script mutually agreeable to 
     Biogen and Nova Factor. If the customer has volunteered information to 
     Biogen or has previously been in contact with Biogen's third party 
     reimbursement agency, Biogen or the agency shall transmit the 
     information to Nova Factor. At Biogen's request, Nova Factor shall 
     assist Biogen in developing a standard intake form for initial customer 
     contact. Nova Factor shall direct to Biogen's customer service operation 
     all potential users of Product who contact Nova Factor directly in 
     accordance with a script mutually agreeable to Biogen and Nova Factor.

4.2  Nova Factor shall ship Product to customers at their homes or to any 
     other residence, office or similar location designated by customer, not 
     including pharmacies, via Federal Express standard overnight delivery 
     service or another mutually agreed to overnight carrier. Nova Factor 
     shall package Products for shipment in insulated shipping units in


                                       5


<PAGE>

     accordance with the applicable SOP. Nova Factor shall use its best 
     efforts to ship Products such that Product having the earliest 
     expiration date is shipped first from available inventory. Nova Factor 
     shall track each shipment of Product to customer and confirm receipt. If 
     product is not received by the intended customer, Nova Factor shall use 
     reasonable efforts to track the missing shipment until found and, if 
     found, shall retrieve the missing shipment. Any shipment not delivered 
     to the intended recipient which is found shall be retrieved by Nova 
     Factor and, if determined by Nova Factor to be unusable, shall be 
     disposed of by Nova Factor.

4.3  Except for initial shipments made to a customer's home or designated 
     location and except where the customer's payor requires preapproval of 
     subsequent shipments. Nova Factor shall, subject to Product 
     availability, ship Product to a customer within 48 hours of receipt of 
     an order. Nova Factor shall use reasonable efforts to obtain 
     reimbursement clearance, if necessary, for anticipated subsequent orders 
     from a customer prior to actual receipt of the subsequent order. Nova 
     Factor shall ship each initial order and any subsequent order which 
     requires reimbursement clearance to a customer's home or designated 
     location within 48 hours of reimbursement clearance unless Biogen and 
     Nova Factor have agreed upon a first shipment program. At Biogen's 
     request, Biogen and Nova Factor shall work together to develop a first 
     shipment program to allow shipment of initial quantities of Product to a 
     patient prior to reimbursement clearance. If the parties have agreed 
     upon a first shipment program, Nova Factor shall comply with the 
     timelines for delivery of Product contained in the program.

4.4  Nova Factor shall be responsible for all billing and collection in 
     connection with its sales of Product. Nova Factor shall not bundle sales 
     of Product with other products or services, provided that Nova Factor 
     may list Product on the same invoice with other products for the same 
     customer, if required by the customer's insurance provider, as long as 
     the Product price and any negotiated discount from or allowance taken 
     with respect to the Product price are listed separately. Nova Factor may 
     bundle shipments of Product with other products for delivery to the same 
     customer, provided that such bundling is covered by an SOP.

4.5  Nova Factor shall be responsible for all costs associated with 
     distribution and delivery of Products to its customers.

     customers, provide the following services for each potential or existing 
     Nova Factor customer who contacts Nova Factor for home delivery of 
     Product:

     (i)     Nova Factor shall collect the relevant insurance information 
             from each new customer who has insurance and shall obtain 
             confirmation of the existence and extent of insurance coverage 
             for Product from the customer's insurance provider or other 
             third party payor. Nova Factor shall use its best efforts to 
             confirm reimbursement coverage within one (1) week of receipt of 
             an order from a customer. Biogen understands that, despite Nova 
             Factor's best efforts, confirmation of reimbursement coverage 
             will often take longer than one (1) week.

     (ii)    Nova Factor shall accept assignment of benefits from each 
             customer with reimbursement coverage unless the customer's 
             insurance provider or other third party payor does not allow 
             assignment of benefits. To effect the assignment of benefits, 
             Nova Factor shall, within two (2) business days of initial 
             contact with each customer, provide to the customer the 
             applicable forms and instructions for assignment of benefits and 
             shall file the forms with the customer's insurance provider or 
             other third party payor at the time of Product shipment and 
             billing.

     (iii)   Upon receipt of the appropriate approval, Nova Factor shall bill 
             and submit the appropriate claims to each customer's insurance 
             provider, third party payor or other responsible party, 
             including Medicaid, but not including Medicare.

     (iv)    Consistent with applicable law and Nova Factor's standard 
             collection policy, a copy of which is attached hereto as 
             Schedule C (the "Nova Factor Collection Policy"). Nova Factor 
             shall use its best efforts to collect the amount allowed from 
             each customer's insurance provider or other third party payor, 
             and shall work with customers and negotiate with providers and 
             third party payors to maximize reimbursement coverage.

     (v)     Nova Factor shall bill patient co-payments, self-pays or 
             deductibles and shall use reasonable good faith efforts to 
             collect such payments consistent with applicable law and the 
             Nova Factor Collection Policy. Nova Factor shall provide Biogen 
             with a copy of any changes to the Nova Factor Collection Policy 
             prior to implementation of such changes.

     (vi)    Nova Factor shall make the intake coordinator function available 
             from 9:00 a.m. to 8:00 p.m., E.S.T, Monday through Friday, 
             except Nova Factor holidays, to answer customer, insurance 
             provider, third party payor and prescriber reimbursement 
             questions. Biogen will, in its sales and marketing material, 
             list Biogen's toll-free number as the number for users of the 
             Product to call with reimbursement questions. When Biogen 
             receives a telephone call from a Nova Factor customer with a 
             reimbursement question, the Biogen customer service 
             representative will transfer the telephone call to Nova Factor.

     (vii)   Nova Factor shall use its best efforts to resolve reimbursement 
             issues of customers who would like to purchase Product from Nova 
             Factor. If Biogen has engaged


                                       7

             to such third party and share relevant information with such 
             third party, as specified in guidelines established by Biogen.

     (viii)  Biogen shall furnish to Nova Factor the criteria for 
             eligibility in Biogen's financial assistance program, and Nova 
             Factor shall direct potential customers who meet the criteria to 
             Biogen's customer service department.

5.2  Nova Factor shall not deny Product to customers who do not have insurance
     or who have insufficient insurance coverage if the customer has the
     ability to self-pay.

5.3  Nova Factor shall be responsible for all costs associated with the 
     services provided under this Section 5.

5.4  Nova Factor shall be responsible for assuring that the services provided 
     under this Section are carried out in a manner consistent with 
     applicable federal and state laws.

     Biogen shall designate.

               confidentiality laws prohibit transfer of the customers' name 
               to the designated distributor, Nova Factor shall transfer the 
               Database and customer information using customer numbers instead
               of names.

               (v)   Nova Factor's obligation to order additional Product 
               when its inventory falls to a one-week supply shall cease and

               Factor on the date of termination at the price paid for the 
               Product by Nova Factor.

         After receipt of the termination notice and during the period 
         thereafter ending six months after termination, Nova Factor shall 
         use reasonable efforts to cooperate with Biogen in ensuring the 
         smooth transition of the services provided by Nova Factor under this

         after termination of this Agreement, Biogen shall reimburse Nova 
         Factor for its reasonable out-of-pocket, non-

       which shall be binding on the other party, except as may be explicitly 
       provided for herein or authorized in writing.

22.7   Except as required by law, neither party shall use the name of the

       not to affect the validity or enforceability of this Agreement, except

       reformation or deletion in which case this Agreement shall terminate.

22.9   Failure of either party to enforce a right under this Agreement shall 
       not act as a waiver of that right or the ability to later assert that 
       right relative to the particular situation involved or to terminate 
       this Agreement as a result of any subsequent default or breach.

22.10  This Agreement shall be construed and enforced in accordance with the 
       laws of the Commonwealth of Massachusetts.

22.11  Unless waived by the parties, any dispute, controversy or claim 
       between the parties arising out of or relating to this Agreement 
       either during or after the term hereof (including the question as to 
       whether any particular matter is arbitrable) shall be solely and 
       finally settled by arbitration conducted in Memphis, Tennessee, if the 
       arbitration is initiated by Nova Factor or in the Boston, 
       Massachusetts metropolitan area, if the arbitration is initiated by 
       Biogen, in accordance with the Commercial Arbitration Rules of the 
       American Arbitration Association then in force (the "Rules"). The 
       party requesting arbitration shall serve upon the other party to the 
       controversy, dispute or claim a written demand for arbitration stating 
       the substance of the controversy, dispute or claim, the contention of 
       the party requesting arbitration, and the name and address of the 
       arbitrator appointed by it. The recipient of such demand shall within 
       twenty (20) days after such receipt appoint an arbitrator and notify 
       the party requesting arbitration of the identity of the arbitrator so 
       selected, and the two arbitrators shall appoint a third, and the 
       decision or award of any two arbitrators shall be final and binding 
       upon the parties. In the event that the two arbitrators fail to 
       appoint a third arbitrator within twenty (20) days of the appointment 
       of the second arbitrator, either arbitrator, or any party to the 
       arbitration, may apply to a judge of the United States District Court 
       for the district in which the arbitration is held for the appointment 
       of the third arbitrator and the appointment of such arbitrator by such 
       judge or such application shall have precisely the same force and 
       effect as if such arbitrator had been appointed by the two 
       arbitrators. If for any reason the third arbitrator cannot be 
       appointed in the manner prescribed by the preceding sentence, either 
       regularly appointed arbitrator, or either party to the arbitration, 
       may apply to the American Arbitration Association for appointment of 
       the third arbitrator in accordance with the Rules. If the parties upon 
       whom the demand for arbitration has been served fail or refuse to 
       appoint an arbitrator within twenty (20) days, the single arbitrator 
       shall have the right to decide alone, and such arbitrator's decision 
       or award shall be final and binding upon the parties. The decision of 
       the arbitrator shall be in writing and shall set forth the basis 
       therefor. The parties shall abide by all awards rendered in 
       arbitration proceedings, and all such awards may be enforced and 
       executed in any court having jurisdiction over the party against whom 
       enforcement of such award is sought. The party losing the dispute 
       which was submitted to arbitration shall pay the administrative 
       charges, arbitrator's fees, and related expenses of arbitration, and 
       each parties legal fees incurred in connection with any such 
       arbitration. This agreement to arbitrate shall be specifically 
       enforceable under the prevailing arbitration law.

                                   ARTICLE II
               AREA OF OPERATION OF PARTNERSHIP AND RELATED RIGHTS
                         AND OBLIGATIONS OF THE PARTNERS


     2.01 Definitions. For purposes of this Agreement, the following terms shall
have the following respective meanings:

     (a) "Target Provider" means all health Caregivers listed on Exhibit A.

     (b) "Caregiver" means the provider of health care at which, or from whom,
the patient is, at the time of any determination made pursuant to the provisions
of this Article II, receiving care, as either an outpatient or inpatient" for
the condition or illness which necessitates the use of goods or services offered

shall be the area encompassed within the 50 mile radius of Dallas, Texas and 
within the city limits of Lubbock, Texas.

     2.03 Non-Competition.

     (a) Restriction on Partner's Activities With Respect to Patients. Each
Partner agrees that, during the term of this Agreement, it shall not compete
with the Partnership by providing therapies, services, supplies or goods which
are encompassed within the definition of the business purposes of the
Partnership (as set forth in Article I of this Agreement) to any patient who has
his principal residence in the Service Area or whose Caregiver is either located
in the Service Area or a Target Provider ("Restricted Patient"). From time to
time, either Partner may, but shall have no obligation to, refer non-restricted
Patients to the Partnership from outside the Service Area.

     (b) Notwithstanding the preceding provisions of this Article II, the
restrictions or activities contained in this Article II shall not apply to
Restricted Patients as defined in the Operating Agreement for the Campus Home
Health L.L.C. formed between the Partners and Zale Lipshy University Hospital,

<PAGE>

question being offered by the Partnership. However, if a Partner wishes to
provide therapies, services, supplies or goods of a type which is encompassed
within the business purposes of the Partnership (as set out in Article I) but
which is not then currently being offered by the Partnership, to Restricted
Patients, the Partner shall first notify the Partnership of its intentions. The
Partnership shall then have * days within which to notify the Partner in
writing that it elects to offer the therapy, services, supplies or goods. During
such * day period the proposing Partner shall not compete with the Partnership
and shall disclose any information reasonably requested by the Partnership as
being necessary to reach a decision as to whether the Partnership should provide
the new therapies, services, supplies or goods. If the Partnership elects to
offer such therapy, services, supplies or goods, the restrictions on competition
shall apply to the therapy, services, supplies or goods for so long as the
Partnership continues such election.

     (c) Neither Partner shall be in violation of this Article II if it has made
reasonable inquiry of the patient and the patient has denied having a principal
residence or Caregiver which would cause the patient to be covered by these
restrictions. However, if the correct information is subsequently discovered
such that the patient should not have been provided therapies, services,
supplies or goods, the Partner shall so advise the patient and shall use

reasonable efforts to encourage the patient to have such therapies, services,
supplies or goods, as the case may be, provided by the Partnership, consistent

termination of the Partnership.

                                   ARTICLE III

agreement of the Partners.

                                   ARTICLE IV
                 PARTNERSHIP INTERESTS AND CAPITAL CONTRIBUTIONS

     4.01. Partnership Interests. The percentage interest (the "Partnership
Percentage") of each Partner in the assets, liabilities, profits, losses, income
and expenses of the Partnership shall be fifty percent (50%).

     4.02. Initial Capital Contribution. Each Partner shall contribute to the
capital of the Partnership the sum of $ . Such contributions shall be in cash
and shall constitute the

                                      - 6 -

<PAGE>



initial capital of the Partnership. Such contributions shall be made within a
reasonable period of time following execution of this Agreement as agreed upon
by the Partners.

     4.03. Additional Capital Contributions. In the event that at one time (or
from time to time) funds in excess of retained operating revenues and any
Partnership borrowings are required by the Partnership for or in respect of its
business or any of its obligations, expenses, costs, liabilities or expenditures
(including, without limitation, operating deficits), the Partners shall
contribute cash to the capital of the Partnership in such amounts as are
determined ("Additional Capital Contribution"), and on such dates as are set
(the "Contribution Date") by the unanimous vote of all members of the Steering
Committee. Each Partner shall contribute its share of such amounts based on its
Partnership Percentage.

     4.04. Failure To Make Additional Capital Contribution. In the event that a
Partner fails to make an Additional Capital Contribution as required under
Section 4.03 hereof, the amount of Additional Capital Contribution made by the
other Partner (the "Contributing Partner") shall not be treated as a Capital
Contribution but shall instead be treated as a loan from the Contributing
Partner to the Partnership. Such loan shall be evidenced in the manner deemed
appropriate by the Contributing Partner and shall be secured by a security
interest in the

<PAGE>

Partnership Receipts (as defined in Section 5.02). Such loan shall bear interest
at an annual rate equal to the lower of: (i) four percent (4%) more than the
prime rate, as set by the Chase Manhattan Bank, N.A., One Chase Manhattan Plaza,
New York, New York 10081, in effect on the Contribution Date; or (ii) the
maximum rate permitted under applicable law; and said loan, principal and
interest, shall be repaid on a quarterly basis from the Partnership Receipts
before distributions are made to the Partners. The amount of the loan to be
repaid each quarter shall be determined by the Steering Committee, provided
however, that the loan shall be repaid as promptly as possible taking into
account the reasonable needs of the Partnership to retain cash for the operation
of the business of the Partnership. All repayments shall be first applied
against interest due before reducing the principal balance of the loan.

     4.05. Interest on Capital Contributions. No interest shall accrue or be
paid the Partners on Capital Contributions and Additional Capital Contributions.

provided in Section 11.02 hereof where there is a Delinquent Partner (as defined
in Section 11.02).

     4.07. No Third Party Benefit. The provisions of Section 4.03 hereof are not
intended to be for the benefit of any creditor or other person (other than a
Partner in his capacity as a Partner) to whom any debts, liabilities or
obligations are owed by, or who otherwise has any claim against, the Partnership
or any of the Partners; and no such creditor or other person shall by reason of
any such foregoing provisions make any claim in respect of any debt, liability
or obligation (or otherwise) against the Partnership or any of the Partners.

Additional Capital Contributions made by such Partner pursuant to Section 4.03
hereafter and (iii) such Partner's Partnership Percentage of the net profits of

Partnership in accordance with the approved Partnership Budget (as described in
Section 7.03 hereof).

     5.03. Allocation of Income and Losses. The net profits and losses of the

allocated to and between the Partners in proportion to their respective
Partnership Percentages.

     6.01. CMC Patients. Partnership will arrange for homecare services to
individual patients discharged from Children Medical Center of Dallas ("CMC")
based upon the assumption that homecare services remain as they are currently
provided by the Partnership. If new homecare services are developed, the
partners will review the situation to arrive at a mutually satisfactory position
on care.

     6.02. Best Efforts Obligations of Partners. The Partners agree to use their
best efforts to promote the sale of services and supplies offered by the
Partnership to Restricted Patients. However, both Partners are in the same
business as Partnership and unless a Partner's actions would violate the
restrictions contained in Article II, the Partners may compete with the
Partnership without such competition constituting a breach of loyalty or other
duty owed by a Partner to the Partnership.

                                   ARTICLE VII
                             PARTNERSHIP MANAGEMENT

     7.01. Steering, Committee. The overall management and control of the
business and affairs of the Partnership shall be vested in the Steering
Committee. The Steering Committee will consist of two persons designated by ACS,

                                     - 11 -

<PAGE>


Committee member will serve at the pleasure of the Partner designating such
member and may be replaced, with or without cause, at any time by such Partner,
except that the member chosen by the Steering Committee itself will serve at the
pleasure of both Partners and shall be replaced, with or without cause, at any
time at the request of either Partner. In the event that the Steering Committee
member selected by the Committee must be replaced, the remaining Steering
Committee members, by unanimous vote, will select a successor. Except with
respect to Partnership Major Decisions as set forth in Section 7.02, approval of
the Partnership Budget or as otherwise provided in this Section with respect to
Steering Committee membership selection, the act of a majority of the members of
the Steering Committee shall constitute the act of the entire Committee, so long
as each member is given written notice at least three days in advance of a
Steering Committee meeting (unless such notice is waived in writing by a member
at any time) of all actions proposed to be taken at that meeting by the Steering
Committee. The presence of a quorum of the Steering Committee members shall be
necessary at any meeting for the transaction of business. A quorum shall consist
of four members of the Steering Committee provided however that any Steering
Committee member appointed by a Partner may be represented by a substitute
designated by the Partner which designated the Steering Committee member who is
to be represented by the substitute.

of the Committee. Meetings of the Steering Committee may, upon the request of
any two members and as otherwise agreed, be held by means of conference
telephone or similar communications equipment by means of which all members
participating in a meeting can hear and speak to each other. The members of the
Steering Committee shall elect a chairman to preside at all the meetings of the
Steering Committee, which chairman will be responsible for providing notice for
meetings and proposed actions to be taken by the Steering Committee, and for
maintaining minutes of Steering Committee meetings.

the Steering Committee, approve in accordance with Section 7.02 hereof a budget
("Partnership Budget") setting forth the estimated receipts and expenditures
(capital, operating and other) of the Partnership for the period covered by the
Partnership Budget. The first Partnership Budget shall be developed from a

Partnership Budget has been approved, the Steering Committee, the members
thereof, and any officers appointed by the Steering Committee in accordance with
Section 7.04 hereof, shall in good faith use their best effort to implement the
Partnership Budget and shall be authorized, without the need for further
approval of the Partners, to make expenditures and incur the obligations as
provided in the Partnership Budget.

     7.04. Officers. The Steering Committee shall be authorized to appoint a
General Manager, and such other officers or agents of the Partnership, with such
titles and responsibilities, as the Steering Committee shall from time to time
designate in accordance with Section 7.01 hereof. To the extent that such duties
have not been contractually delegated to a third party, the Steering Committee
may authorize officers of the Partnership to exercise any of the powers or to
carry out any of the responsibilities of the Steering Committee set forth in
Section 7.01(b) hereof, provided, however, that the Steering Committee may not
delegate to any officer or officers of the Partnership the responsibility (i)
for making Partnership Major Decisions, or (ii) to carry out any of the
responsibilities of the Steering Committee described in Section 7.01(b)(x)
hereof. Any officer appointed by the Steering Committee may be removed at any
time from such office, with or without cause, by the Steering Committee, by
written notice to such officer, as provided in Section 7.01(b) hereof.

     7.05. Audit. Either Partner may at its discretion, request a consolidated

                                  ARTICLE VIII
                            OPERATIONS AND EMPLOYEES

                                     - 21 -

<PAGE>


     8.01. Operations. Notwithstanding the restriction that the Partnership
shall not enter into any separate agreement with either Partner without the
written consent of the Partner which is not a party to such agreement, both
Partners consent and agree that as needed the Partnership may contract with NF
or its parent, Southern Health Systems, Inc. ("SHS") for certain supplies,
equipment, solutions and other materials and for the performance of certain
services as may be needed and reasonably available from NF or SHS. Consent of
the Steering Committee shall be required for entering into these contracts.

     8.02. Employee Protection. During the term of this Agreement and for a
period of eighteen (18) months following termination of this Agreement, each
Partner agrees that neither it, nor any entity associated with it or under its
control will hire any employee of the Partnership who, immediately prior to
employment by the Partnership, was an employee of the other Partner (or its
corporate affiliates or subsidiaries). This limitation will be subject to waiver
based on written consent of both Partners.

     8.03. Proprietary Information. Each Partner is currently engaged in the
same business as the Partnership and each Partner has developed, or may develop
during the term hereof, certain formulas, products, methods of doing business,
customer lists and other proprietary information which the Partner deems to be

                                     - 22 -

<PAGE>


confidential and a trade secret. Some of these formulae, products, methods and
other proprietary information will be made available to the Partnership, and
thus become known to the other Partner. It is contemplated that each employee or
agent of the Partnership who will be exposed to such confidential information
will be required to execute a confidentiality agreement. Each Partner also
agrees that it will not duplicate, make use of, or disclose, in any manner
whatsoever, any information which is deemed to be confidential by the other
Partner, either during or after the term of this Agreement, without the express
prior written consent of the other Partner. Each Partner further agrees that it
will cause its employees and agents who will have access to such information to
execute a confidentiality agreement similar to that executed by employees and
agents of the Partnership.

     In the event that any information deemed to be confidential by a Partner is
provided to the Partnership or its employees or agents in writing, the Partner
providing same shall mark the writing as "confidential". In the event that such
information is provided in non-written form such as orally, by audio tape,
videotape or computer software or disc, the Partner claiming such information to
be confidential shall furnish to the other Partner and/or the Partnership's
employees and agents a written list containing a brief description of such item
and designating such item as confidential. Upon termination of this Agreement
all copies of any information hereunder deemed, or designated as, confidential
by a 

                                     - 23 -

<PAGE>



Partner shall be returned to the Partner who supplied the information, or who
designated same as confidential. Notwithstanding the preceding provisions the
following types of information provided by a Partner shall always be deemed
confidential whether or not so designated: Patient records; prescription files;
lists of patient names, addresses or phone numbers; lists of referring
practitioner names, addresses or phone numbers; costs of goods and supplies; and
financial records of the Partner.

     It is recognized and acknowledged that damages caused by a Partner's breach
of this Section would be difficult to ascertain and would not adequately
compensate the other Partner for its losses. Therefore, both Partners agree that
the Partner claiming a breach of this Section shall be entitled to injunctive
relief to restrain the commission or continued commission of said breach either
through the arbitration procedures set out herein or, at the injured Partner's
discretion, by seeking such relief from a court of competent jurisdiction.

     Notwithstanding the preceding paragraphs of this Section, this restriction
shall not apply to (i) any information which is not deemed confidential
hereunder, or which has not been designated as confidential in the manner
specified herein, (ii) any information which was known to a Partner prior to its
disclosure by the other Partner, (iii) any information which is or becomes
public knowledge 

                                     - 24 -

<PAGE>


through no failure of a party bound by this Agreement, or (iv) any information
which is independently developed by a party hereto.

     It is further contemplated that each Partner will execute a confidentiality
agreement with the Partnership by which, subject to Sections 11.04 and 14.01
herein, each will agree not to disclose during the term of the Partnership
confidential information developed by the Partnership.

                                   ARTICLE IX
                                   ACCOUNTING

     9.01. Fiscal Year. The fiscal year of the Partnership for purposes of
accounting and federal and local income and other taxes shall begin on January 1
and end on December 31 of each year of the term.

     9.02. Books and Records. The Steering Committee shall establish, maintain
and keep accurate, full and complete books of account and records (the
"Partnership Books") showing the assets and liabilities, revenues and
expenditures, and all other aspects of the operations, transactions and
financial condition of the Partnership (including changes in the respective
capital accounts of the Partners). The Partnership Books shall be maintained at
the principal office of the Partnership or at such other place reasonably
designated by the Steering Committee, and each Partner and its authorized
representatives shall have access to the 

                                     - 25 -

<PAGE>


Partnership Books during ordinary business hours. The Partnership Books shall be
maintained in accordance with generally accepted accounting principles,
consistently applied.

     9.03. Financial Reports. The Steering Committee shall cause to be prepared
and submitted to each Partner, within one hundred fifty (150) days after the end
of each fiscal year, unaudited financial statements for the fiscal year showing
the revenues and expenditures, and the assets and liabilities, of the
Partnership. In addition, the Steering Committee shall cause to be prepared and
submitted to each Partner, within thirty (30) days after the end of each month,
an unaudited financial statement for that month, showing the revenues and
expenditures, and the assets and liabilities, of the Partnership for such month.

     9.04. Bank Accounts. All receipts, funds and income of the Partnership
shall be deposited in an account or accounts in the name of the Partnership in
such bank or banks as shall be designated by the Steering Committee. All such
bank accounts shall be owned by both Partners, and the signatories for such bank
accounts shall be duly authorized representatives selected by both Partners,
together with such other persons as the Partners may jointly designate for
specific accounts. No check to one Partner shall be issued without the signature
of a representative of the other Partner. There shall be no commingling of the
monies and funds of the Partnership with monies and funds of any other entity,

                                     - 26 -

<PAGE>



and such monies and funds shall be maintained in separate and distinct accounts
of the Partnership.

     9.05. Tax Status and Tax Returns. Each of the Partners hereby recognizes
that, for United States federal income tax purposes, the Partnership will be
subject to all provisions of Subchapter K of Chapter 1 of Subtitle A of the
United States Internal Revenue Code of 1986, as amended. The Steering Committee
shall prepare the informational U.S. federal, state and municipal tax returns
required to be filed by the Partnership, and all other tax returns required to
be filed by the Partnership; provided, however, that the filing of U.S. federal,
state, municipal and other tax returns shall not be construed to extend the
purposes of the Partnership or expand the obligations or liabilities of the
Partners.

                                    ARTICLE X
                      RESTRICTIONS ON TRANSFER OF INTERESTS
                     IN PARTNERSHIP, RIGHT OF FIRST REFUSAL


     10.01. Restrictions on Transfer. During the term of this Agreement, neither
Partner may, directly or indirectly sell, transfer, assign, give, pledge,
syndicate, hypothecate, encumber, alienate or otherwise dispose of (voluntarily
or involuntarily, by operation of law or otherwise) all or any part of its
interest in the Partnership without the prior consent of the other Partner,
except that either Partner may transfer not less than all of its interest in the
Partnership (a) to a corporation which is wholly

                                     - 27 -

<PAGE>


owned by such Partner, or which acquires substantially all of the assets and
assumes substantially all of the liabilities of such Partner (including
specifically assuming in writing all of the Partner's obligations under this
Agreement) or (b) in the manner provided in Section 10.02 hereof. If a loan to
the Partnership from a Partner who desires to sell its Partnership interest
remains outstanding at the time of sale, all of the selling Partner's rights in
said loan must be sold as part of the selling Partner's Partnership interest.

     10.02. Right of First Refusal. This Section sets forth a procedure by which
a Partner may sell all of its interest in the Partnership, but does not
authorize a Partner to sell less than all of its interest in the Partnership
without the consent of the other Partner. In the event a Partner desires to sell
all (but not a part) of its interests in the Partnership, it shall first notify
and fully inform the other Partner in writing of the identity of the proposed
buyer ("Buyer") and the proposed terms and conditions of such proposed sale
("Notice of Proposed Sale") and shall afford the non-selling Partner the
opportunity, within thirty (30) days after receiving such notice, to elect to
purchase such interests in accordance with such proposed terms and conditions by
delivery of written notice to this effect to the selling Partner. In the event
the non-selling Partner shall so elect to make a purchase of such interests on
such terms and conditions, the closing on the purchase will take place according
to the proposed terms and conditions of 

                                     - 28 -

<PAGE>




the sale, or, if not specified, within a reasonable period (but not more than
ninety (90) days) after such election to purchase is made. In the event the
non-selling Partner does not so elect, within the 30 days period to purchase
such interests so offered, the selling Partner will then be free to sell to the
proposed Buyer all (but not part) of such interests on terms no less favorable
to the selling Partner than the proposed terms and conditions specified in the
Notice of Proposed Sale within a period of one hundred and twenty (120) days
after the end of such 30 day period. In the event that the sale does take place
to the proposed Buyer in compliance with this Section within the 120 day period,
the selling Partner shall give written notice to this effect to the non-selling
Partner no later than the date of the closing thereof. At any time following
receipt of the Notice of Proposed Sale and prior to expiration of 30 days
following the closing thereof, the nonselling Partner shall have the right (by
delivering notice to the selling Partner or to the Buyer (if the sale has
closed)) to terminate this Agreement. In the event a sale of such interests is
not made by the selling Partner to the proposed Buyer during such 120 day
period, any sale by that Partner of its interests in the Partnership will
require compliance anew with the provisions of this Section.

                                   TERMINATION

     11.01. Partnership Termination. The Partnership shall terminate upon the
first to occur of the following events:

     (a) upon the written agreement of the Partners to terminate this Agreement:

     (b) upon written notice by either Partner (the "Non-Defaulting Partner"),
if the other Partner (the "Defaulting Partner") shall fail to perform its
obligations hereunder, including without limitation the failure to make its
share of Additional Contributions as required by Section 4.03 hereof (the
"Default"), and such Default shall continue for a period of at least forty-five
(45) days after written notice of such Default from the Non-Defaulting Partner
to the Defaulting Partner;

     (c) upon the permanent cessation or abandonment of the business of the
Partnership;

     (d) upon 12 months written notice of termination by either Partner;
provided, however, that neither Partner may request termination under this

Partners in an amount equal to their respective Partnership Percentage in the
Partnership. If assets other than cash are distributed, such assets shall be

                                   ARBITRATION

     Except as otherwise provided in Section 8.03, any dispute, controversy or
claim between the Partners arising out of or relating to this Agreement either
during or after the term thereof (including the question as to whether any
particular matter is arbitrable) shall be solely and finally settled by
arbitration conducted in Dallas, Texas, in accordance with the Commercial
Arbitration Rules of the American Arbitration Association then in force (the
"Rules"). The Partner requesting arbitration shall serve upon the other Partner
to the controversy, dispute or claim a written demand for arbitration, stating
the substance of the controversy, dispute or claim, the contention of the
Partner requesting arbitration, and the name and address of the arbitrator

                                     - 34 -

<PAGE>



appointed by it. The recipient of such demand shall within 20 days after such
receipt appoint an arbitrator and notify the other Partner of the identity of
the arbitrator so selected, and the two arbitrators shall appoint a third, and
the decision or award of any two arbitrators shall be final and binding upon the
parties. In the event that the two arbitrators fail to appoint a third
arbitrator within 20 days of the appointment of the second arbitrator, either
arbitrator, or either party to the arbitration, may apply to a judge of the
United States District Court located in or nearest to Dallas, Texas for the
appointment of the third arbitrator, and the appointment of such arbitrator by
such judge on such application shall have precisely the same force and effect as
if such arbitrator had been appointed by the two arbitrators. If for any reason
the third arbitrator cannot be appointed in the manner prescribed by the
preceding sentence, either regularly appointed arbitrator, or either party to
the arbitration, may apply to the American Arbitration Association for
appointment of the third arbitrator in accordance with the Rules. Should the
party upon whom the demand for arbitration has been served fail or refuse to
appoint an arbitrator within 20 days, the single arbitrator shall have the right
to decide alone, and such arbitrator's decision or award shall be final and
binding upon the parties. The decision of the arbitrator shall be in writing and
shall set forth the basis therefor. The Partners shall abide by all awards
rendered in arbitration proceedings, and all such awards may be enforced and
executed upon in any court having jurisdiction over 

                                     - 35 -

<PAGE>



the party against whom enforcement of such award is sought. The Partners shall
divide equally the administrative charges, arbitrator's fees, and related
expenses of arbitration, but each Partner shall pay its own legal fees incurred
in connection with any such arbitration. This agreement to arbitrate shall be
specifically enforceable under the prevailing arbitration law and the parties
stipulate that this Agreement involves interstate commerce.

hereinafter set forth;

     NOW, THEREFORE, for and in consideration of the mutual promises contained
herein and for other good and valuable consideration, the receipt and adequacy
of which is hereby acknowledged, the parties hereto agree as follows:

<PAGE>

         1.        Services to be Provided by SHS.  During the term of this

Agreement, SHS agrees to provide or arrange for the provision of, the following
services to THPR:

         A. Billing, Reimbursement, Collection and Financial Counseling
Services.

                  (i) Services. SHS shall provide such billing, reimbursement,
                  collection and financial counseling services as are required,
                  or reasonably requested, by THPR in conducting its Drug
                  Distribution Business, including the preparation, transmitting
                  and monitoring of all bills to patients of THPR's Drug

                  requests or otherwise assisting patients of THPR's Drug
                  Distribution Business in seeking reimbursement from all third
                  party payors for the services provided to such patients by
                  THPR, collecting amounts due THPR from patients or third
                  parties, and counseling patients regarding the options
                  available to them in paying for the Drugs and related services
                  provided to them by THPR. THPR shall establish all patient
                  charges for 

                                           2

<PAGE>

                  such Drugs and related services provided by THPR to the 
                  patients.

                  (ii) Clearance of Patients. SHS agrees that it will not commit
                  to provide Drugs or related services to any patient until such
                  patient is approved by THPR. THPR shall promptly notify SHS as
                  to any potential patient and shall obtain such patient data as
                  shall be specified by SHS. SHS agrees to promptly investigate
                  a potential patient's insurance coverage and financial ability
                  to pay and to notify THPR as to the patient's financial
                  ability to pay for Drugs or related services from THPR. THPR
                  shall thereafter obtain all documentation necessary to file
                  claims with third party payors and forward same to SHS. SHS
                  shall have no liability for relying upon information provided
                  by third party payors concerning coverage in the event that
                  such information shall subsequently prove to be incorrect.

                  (iii) Collection and Disbursement. SHS shall monitor and
                  coordinate collection, for and on behalf of THPR, of all
                  monies due to THPR from patients and/or third party payors for
                  Drugs and related services. SHS shall deposit said funds into
                  a bank account designated by 

                                           3

<PAGE>

                  THPR. SHS shall not have authority to disburse funds from
                  said bank account. However, funds from said Account, in an
                  amount determined by THPR, shall be deposited in a separate
                  operating account, and SHS shall have authority to disburse
                  funds from this operating account as necessary to carry out 
                  the management functions specified herein. Collections of all
                  accounts are performed by SHS on behalf of THPR and SHS shall
                  not be responsible for any failure to collect such accounts. 
                  SHS hall use reasonable efforts to collect said accounts 
                  (but not greater than those efforts used in the collection of
                  its own accounts), but SHS shall not be required to institute
                  suit for collection or incur any extraordinary expenses in 
                  attempting to collect these receivables unless such action is
                  approved by the Steering Committee and the costs are paid by 
                  THPR.

     B. Accounting and Financial Reporting. SHS shall provide the following

appropriate invoices, applying credits to patient accounts and applying
write-offs and adjustments approved by THPR) and (iv) reconciliation of the Drug
Distribution Business bank account statements of THPR. SHS shall not make
provision for any annual audit of THPR, and such audit if desired by THPR shall
be the responsibility of THPR and shall be conducted by such independent
accounting firm as THPR may select. SHS agrees to cooperate with the accounting
firm in the conduct of the audit of THPR or any other accounting procedure for
which the accounting firm may be engaged by THPR. THPR shall make available to
SHS such information and documentation as may be needed to enable SHS to prepare
the tax returns and financial reports specified herein.

                  (i) Responsibilities. THPR hereby appoints SHS to manage and
                  supervise the operation of THPR's day-to-day operations of its

                  day-to-day operations of THPR's Drug Distribution Business.

                  be subject to the direction, input and general guidance of 
                  the Steering Committee. The Steering Committee shall 
                  communicate to SHS all decisions of that Committee which

                  Business and upon the direction of the Steering Committee, SHS
                  personnel shall perform sales calls and other related
                  marketing activities. Such marketing materials and procedure

                  for review by THPR at SHS's offices.

                  (iii) Personnel. SHS shall designate certain SHS personnel to

                  Distribution Business. Subject to the reimbursement provisions
                  set out in

<PAGE>

                  Section 2 hereinbelow, SHS shall solely be responsible for 
                  all costs associated with such employment, including without 
                  limitation, its employees' salaries, federal and state income
                  tax withholding, Social Security tax withholding, workmen's 
                  compensation benefits and fringe benefits.

                  (iv) Steering Committee. The overall management and control of
                  the business and affairs of THPR's Drug Distribution Business
                  shall be vested in a Steering Committee as described in the
                  THPR Partnership Agreement.

     2. Compensation. THPR shall pay a monthly fee to SHS for the reimbursement,
accounting, management and computer services specified herein as set out on
Exhibit A attached hereto and made a part hereof, plus an amount equal to *
percent (*%) of net patient revenues of THPR during that month. Net patient
revenue shall be determined in accordance with generally accepted accounting
principles. SHS will bill THPR for all charges for services and employment costs
on a monthly basis. All charges shall be due and payable by THPR * (*)
days from the end of the month in which the changes reflected on SHS's invoice
to THPR were earned by SHS.

         Notwithstanding any provision herein to the contrary, the * percent
of net patient revenues when added to similar fees (excluding reimbursement,
accounting, management and computer service fees as described on Exhibit A) paid
to SHS by all other partnerships between an SHS affiliate and Alternative Care
Systems, Inc. shall not exceed for fiscal year July 1, 1994 through June 30,
1995 the sum of $*. If the total should exceed this amount, SHS shall
determine which of the fees paid by these partnerships to SHS shall be reduced.
The management fees are based on the assumption that the homecare reimbursement
market remains relatively stable. If significant changes in the Texas Medicaid
levels of reimbursement or other unforeseen material changes occur, then the
parties to this Agreement will mutually review other options for compensation.
The management fees set out in this section will be effective from July 1, 1994
to June 30, 1995 unless one of the unforeseen events referenced hereinabove
should occur. Both parties will review the previous years fees and their
reasonableness on an annual basis and resolve outstanding issues and agree to
the fees and cap on fees for the following year. In the event that the parties
cannot agree, the management fees shall remain the same as for the prior fiscal
year ending June 30.

     3. THPR Costs. It is agreed and understood that during the term of this
Agreement, THPR shall also be responsible for

the costs incurred by SHS in providing the services which it is obligated to
provide under Sections 1A, 1B and 1C hereunder (including without limitation,
telephone, travel, office supplies and postage). In addition to the preceding
provision, THPR shall be responsible for the costs of salaries and fringe
benefits for THPR's employees, if any; outside auditor fees; acquisition of
Drugs; facility lease costs; capital expenditures; principal and interest on
loans; payroll taxes for its employees, if any; and the cost of preparing
Federal and state Income Tax returns, and all sales taxes on sales to patients.
THPR shall contract for all such expenses for and in the name of THPR, without
basing the same upon SHS's credit, and SHS shall not be liable to third party
providers for the costs of such goods and services. SHS shall file for and on
behalf of THPR all sales and use tax returns necessary in the operation of
THPR's Drug Distribution Business.

     4. Subcontracting. The parties to this Agreement recognize that SHS may
provide to THPR certain of the services which it is obligated to provide under
this Agreement by means of subcontracts with third parties. However, no such
subcontract shall release SHS from its duties and responsibilities under this
Agreement with respect to the services so subcontracted.

     5. Term. This Agreement shall be for a term beginning on July 1, 1994 and
ending on March 31, 1999, unless otherwise terminated in accordance with this
section. This Agreement shall automatically terminate upon (i) SHS or THPR
ceasing to exist, (ii)either party ceasing to be licensed to sell Drugs, (iii)
either party permanently ceasing to engage in the Drug Distribution Business,
(iv) the mutual agreement of the parties, (v) the insolvency or bankruptcy of

against either party of bankruptcy, reorganization, arrangement or insolvency
proceedings. In addition, if either party hereto shall breach the terms of this
Agreement, the nonbreaching party may give written notice of the breach to the
breaching party, and if said breach is not cured within 21 calendar days
following the giving of said notice, this Agreement shall at the option of the
nonbreaching party be terminated. Furthermore, notwithstanding any other
provision of this Agreement, either party may terminate this Agreement upon
giving 90 days prior written notice to the other party.

     6. Force Majeure. The obligations of SHS hereunder shall be excused during
any period of delay caused by matters such as 

                                           10
<PAGE>

strikes, acts of God, shortages of raw materials or power, inability to obtain
product, governmental action or compliance with governmental requirements,
whether voluntary or pursuant to order, or any other matter which is beyond the
reasonable efforts of SHS to control.

     7. Severability. If any one or more of the provisions of this Agreement
shall for any reason be held illegal or invalid, such illegality or invalidity
shall not affect any other provision of this Agreement and this Agreement shall
be enforced as if such illegal or invalid provision had not been contained
herein.

     8. Confidentiality. Each party has developed or may during the term hereof
develop certain formulae, products, methods of doing business, customer lists
and other proprietary information which that party deems to be confidential and
a trade secret. In the course of fulfilling their respective obligations
hereunder, some of these formulae, products, methods and other proprietary
information will become known to the other party hereto. It is contemplated that
each employee or agent of the parties who will be exposed to such confidential
information will be required to execute a confidentiality agreement with each
party hereto. Each party also agrees that it will not duplicate, make use of, or
disclose, in any manner whatsoever, any 

                                           11
<PAGE>

information which is deemed to be confidential by the other party, either during
or after the term of this Agreement, without the express prior written consent
of the other party hereto.

      In the event that any information deemed to be confidential by a party is
provided to the other party or its employees or agents in writing, the party
providing same shall mark the writing as "confidential." In the event that such
information is provided in non-written form such as orally, by audiotape,
videotape or computer software or disc, the party claiming such information to
be confidential shall furnish to the other party a written list containing a
brief description of such item and designating such item as confidential. Upon
termination of this Agreement, all copies of any information hereunder deemed,
or designated by a party as, confidential shall be returned to the party who
supplied the information, or who designated same as confidential.
Notwithstanding the preceding provision, the following types of information
provided by a party shall always be deemed confidential, whether or not so
designated: patient records; prescription files; costs of goods and supplies;
and financial records of the party.

     Notwithstanding the preceding sections, this restriction shall not apply
(i) to any information which is not deemed confidential hereunder, or which has
not been designated as 

                                           12
<PAGE>

confidential in the manner specified herein, (ii) to any information which was
known to a party prior to its disclosure by the other party, (iii) to any
information which is or becomes public knowledge through no failure of a party
bound by this Agreement, (iv) to any information which is independently
developed by a party hereto, or (v) to the extent that such restrictions
conflict with the terms of the THPR Partnership Agreement.

     It is recognized and acknowledged that damages caused by a party's breach
of this Section would be difficult to ascertain and would not adequately
compensate the other party for its losses. Therefore, both parties agree that
the party claiming a breach of this Section shall be entitled to injunctive
relief to restrain the commission or continued commission of said breach by
seeking such relief from a court of competent jurisdiction.

         9.   Service to Other Businesses.  THPR acknowledges that

SHS offers its services to other business, and THPR agrees that no provision
contained herein shall restrict or prohibit SHS from providing services to
others in addition to THPR as long as the performance of said services does not
interfere with the performance of SHS's obligations hereunder.

Social Security Act, SHS shall, upon proper request, allow the United States
Department of Health and Human Services, the Comptroller General of the United
States and their duly authorized representatives, access to this Agreement and
to all books, documents and records necessary to verify the nature and extent of
the costs of the services provided by SHS under this Agreement at any time
during the term of this Agreement and for an additional period of four (4) years
following the last date services are furnished under this Agreement.

         11. Nonassignability. The rights, duties and responsibilities of the
parties hereto are personal in nature and shall not be assigned without the
express written consent of the other party except that SHS may subcontract with
other parties to perform some or all of its duties hereunder.

     12. Applicable Law. This Agreement shall be construed in accordance with
the laws of the State of Tennessee and the laws of the State of Tennessee shall
govern the rights, duties, liabilities and responsibilities created hereunder.

         18. Fairness. The parties hereto recognize that Nova Factor, Inc. is a
general partner of THPR. Each party acknowledges that the terms of this
Agreement are fair and reasonable to both parties and that it is in the best
interest of each party to enter into this Agreement. Each party further
acknowledges that the terms of this Agreement were negotiated and that the

                                      FEES TO NFI

In exchange for the goods and services provided by NFI under this Agreement, 
the Partnership agrees to pay to NFI the following amounts:

     A.   * of the Partnership in exchange for computer services.

     B.   * of the Partnership for reimbursement services.

     C.   * per month for accounting and reporting services.

     D.   Reimbursement on a monthly basis for all employment costs incurred 
          by NFI in providing NFI personnel to perform the services set out 
          herein. Employment costs shall mean the salary, payroll and FICA 
          taxes, and the cost of all fringe benefits paid to or for the 
          employee by NFI, plus all incremental costs incurred by NFI for and 
          on behalf of the Partnership, such as workers' compensation 
          insurance, automobile insurance, and incremental costs of property 
          and casualty insurance coverage. In the event that any NFI employee 
          devotes only a portion of his or her time to the performance of 
          services for the Partnership, the employment costs for that 
          employee, which is charged to the Partnership, shall be a prorated 
          portion of the total employment costs determined by multiplying the 
          total costs by a fraction, the numerator of which is the time spent 
          by the employee for the Partnership and the denominator of which is 
          the total hours worked by the employee during that month.

     E.   In exchange for pharmaceutical solutions supplied by NFI, the 
          Partnership will pay on a monthly basis to NFI an amount equal to 
          NFI's * said medical equipment, services and supplies. NFI's * 
          shall mean the * by NFI to its supplier for the medical equipment, 
          services and supplies, plus taxes and freight.

For purposes of this Agreement, the Partnership's * shall mean all charges 
made by the Partnership in a given month, determined on an accrual basis, 
regardless of whether such accounts are actually collected, and * shall not 
be reduced for *; taxes, depreciation, principal payment on loans, 
distributions to Partners, other reserves, fees paid to NFI hereunder, or any 
other expenses.

The fees due to NFI shall be determined on a monthly basis by NFI and NFI 
shall submit monthly invoices to the Partnership setting out the amounts due 
NFI for said month. The invoices for NFI's services shall be due thirty (30) 
days from the receipt of same by the Partnership.

Southern Health Systems, Inc., a Tennessee corporation ("SHS"), Texas Health 
Pharmaceutical Resources, a Tennessee general partnership (hereinafter 
referred to "THPR"), and Nova Factor, Inc., a Tennessee corporation 
(hereinafter referred to "NFI").

                           WITNESSETH

         WHEREAS, SHS and THPR entered into a Drug Distribution Business 
Management and Service Agreement dated           , 1995 ("Service 
Agreement"); and

         WHEREAS, THPR is engaged in the business of providing distribution 
of drugs and SHS is in the process of withdrawing from that business; and

         WHEREAS, THPR, NFI and SHS desire to amend the Service Agreement to 
substitute NFI for SHS and to provide that SHS's obligations thereunder shall 
hereinafter be performed by NFI.

         NOW THEREFORE, for and in consideration of the mutual promises 
contained herein and for other good and valuable consideration, the receipt 
and adequacy of which is hereby acknowledged, the Service Agreement is 
amended, effective as of the date hereof ("Effective Date"), as follows:

         1.       Except as set out in Section 4 hereof, THPR, SHS and
                  NFI agree that from and after the Effective Date, all
                  privileges, rights, duties and obligations of SHS under
                  the Service Agreement shall be and hereby are assigned
                  and transferred to NFI and that the Service Agreement
                  shall, from the Effective Date, be an agreement solely
                  by and between NFI and THPR.

         2.       Except as set out in Section 4 hereof, NFI hereby
                  accepts the assignment and transfer of all rights,
                  privileges, duties and obligations of SHS under the
                  Service Agreement, and from and after the Effective
                  Date, agrees to carry out the duties and obligations of
                  SHS set forth in the Service Agreement.

         3.       All references to SHS in the Service Agreement shall be
                  deleted and NFI shall be substituted therefor.

         4.       From and after the Effective Date, SHS shall have no
                  further liability or responsibility under the Service
                  Agreement, and THPR shall have no further obligation

                  were to be performed by THPR or SHS and all rights and
                  privileges which accrued in favor of SHS or THPR, prior
                  to the Effective Date, shall continue to be in effect,
                  including the indemnity contained in the Service
                  Agreement for matters occurring prior to the Effective
                  Date.  In addition, SHS and THPR agree to continue to
                  observe the confidentiality provisions of the Service
                  Agreement, as well as their respective obligations to
                  maintain records, all as concern information and
                  records generated prior to the Effective Date.  All
                  monies earned or owed to SHS or THPR under the Service
                  Agreement prior to the Effective Date shall promptly be
                  paid in accordance with the terms of the Service
                  Agreement as in effect prior to the Effective Date.

                  Agreement entitled Compensation is amended to delete
                  the reference to "* of THPR
                  during that month" and to substitute in place thereof
                  the following:  "* of THPR
                  during that month."  In addition, Section 2 is amended
                  to provide that if the total sum of $* is
                  exceeded, the excess shall be split among NFI,
                  PharmaThera, Inc., HealthEffects, Inc. and CliniCall,
                  Inc. in a manner agreed upon by those four parties.  It
                  is further agreed that these changes in Section 2 of
                  the Service Agreement shall be in effect until June 30,
                  1996, at which time, NFI and THPR will negotiate a new
                  fee arrangement mutually acceptable to both parties.

         6.       All provisions of the Service Agreement shall
                  hereinafter be in full force and effect by and between
                  NFI and THPR except as otherwise specifically stated
                  herein.

         7.       NFI and SHS also entered into a Drug Distribution
                  Management and Services Subcontract dated             ,
                  1995 (the "Subcontract").  The parties hereby agree
                  that said Subcontract shall be, and is, terminated and
                  cancelled as of the Effective Date.

         IN WITNESS WHEREOF, each of the parties hereto have caused this 
Amendment to be executed by their duly authorized officers this    day of     
       , 1996.

                  Company shall inform THPR, in writing, within 2 days of the

                  such engagement. For this purpose, Company hereby 
                  constitutes and appoints THPR as Company's agent and 
                  attorney in fact with full power of sub-stitution or 
                  revocation, and hereby grants to THPR the rights and powers 
                  enumerated herein, for the purpose of taking any action or

                  Company's provider number, for the limited purposes of 
                  billing Company's patients, filing claims with the 
                  applicable third party payors to effectuate payment for 
                  Hemophilia Therapy Goods, and collecting and depositing 
                  accounts receivable. Bills shall be on the appropriate 
                  standardized form (i.e., 1500 claim form) or through 
                  electronic filing if available.

                  4. Collection and Disbursement. THPR shall monitor and 
                  coordinate collection of all monies due to the Company from 
                  patients and/or third party payors for Hemophilia Therapy 
                  Goods and related services. THPR shall deposit all Company 
                  funds received by it into the bank account designated by 
                  the Company. THPR shall not have authority to disburse 
                  funds from said bank account. Collections of all accounts 
                  are performed by THPR on behalf of the Company and THPR 
                  shall not be responsible for any failure to collect such 
                  accounts. THPR shall use reasonable efforts to collect said 
                  accounts (but not greater than those efforts used in the 
                  collection of its own accounts) but THPR shall not be 
                  required to institute suit for collection or incur any 
                  extraordinary expenses in attempting to collect these 
                  receivables unless such action is approved by the Company 
                  and the costs are paid by the Company.

                  warehouse for Outpatient Drugs ordered by Company until 
                  such time as THPR receives a request from Company to 
                  dispense outpatient drugs to an Approved Patient of the 
                  Company and that Company retains legal title to such

                  or her freedom to choose a pharmacy provider on a form

                  the patient does not elect to use the contracted services 
                  of THPR, the patient may obtain the prescription from the 
                  Company and then obtain the Hemophilia Therapy Goods from

                  property of THPR; however, copies will be made available to 
                  Company to the extent allowed by law.

         G. Prohibition of Drug Diversion. THPR and Company agree that they 
         will not resell or transfer Hemophilia Therapy Goods purchased at 
         section 340B pricing to an individual who is not a Approved Patient 
         of Company. Company understands that it can be removed from the list 
         of covered entities because of its participation in drug diversion, 
         a 340B(a)(5) prohibition, and no longer be eligible for 340B 
         pricing. Company understands that Agreement is contingent upon it 
         maintaining its Covered Entity status and agrees to inform THPR (no 
         later than one (1) business day after becoming aware of same) of the 
         loss of its status as a Covered Entity.

                  1.       Dispensing of Hemophilia Therapy Goods.  THPR will 
                           dispense Hemophilia Therapy Goods only in the 
                           following circumstances:

                           a. Upon presentation of a prescription bearing 
                           Company's name, the eligible patient's name, a 
                           designation that the patient is an eligible 
                           patient, and the signature of a legally qualified 
                           health care provider affiliated with Company; or

                           b. Receipt of a prescription ordered by 

                                       12

<PAGE>

                           telephone on behalf of an eligible patient by a 
                           legally qualified health care provider affiliated 
                           with Company who states that the prescription is 
                           for an eligible patient. Company will furnish a 
                           list to THPR of all such qualified health care 
                           providers and will update the list of providers to 
                           reflect any changes. If THPR is found to have 
                           violated the drug diversion prohibition, THPR will 
                           pay Company the amount of the discount in question 
                           so that Company can reimburse the manufacturer.

                  2.       Patient Eligibility.

                           a. Company and THPR will develop a system to 
                           verify patient eligibility. As used in the context 
                           of this Agreement, an individual is a "patient" of 
                           Company (with the exception of State-operated or 
                           funded AIDS drug purchasing assistance programs) 
                           only if:

                                    1.      Company has established a 
                                    relationship with the individual, such 
                                    that Company maintains records of the 
                                    individual's health care; and

                                    2.       the individual receives health 
                                    care services from a health care 
                                    professional who is either employed by 
                                    Company or provides

                                       13

<PAGE>

                                    health care under contractual or other 
                                    arrangements (e.g. referral for 
                                    consultation) such that responsibility 
                                    for the care provided remains with 
                                    Company; and

                                    3. the individual receives a health care 
                                    service or range of services from Company 
                                    which is consistent with the service or 
                                    range of services for which grant funding 
                                    or Federally-qualified health center 
                                    look-alike status has been provided to 
                                    Company.

                           b. An individual is not a "patient" of Company for
                           purposes of 340B if the only health care service
                           received by the individual from Company is the
                           dispensing of a drug or drugs for subsequent
                           self-administration or administration in the home
                           setting.

                           c. An individual registered in a State-operated or
                           funded AIDS drug purchasing assistance program
                           receiving financial assistance under title XXVI of
                           the Public Health Services Act will be considered a
                           "patient" of Company for purposes of this
                           definition if so registered as eligible by the
                           State program.

                                       14

         H. Tracking Service. THPR, with the assistance of Company, will
         establish and maintain a tracking system suitable to prevent diversion
         of section 340B discounted drugs to individuals who are not Approved
         Patients of the Company. For example, such a tracking system might
         include quarterly sample comparisons of eligible patient prescriptions
         to the dispensing records and a six (6) month comparison of 340B drug
         purchasing and dispensing records as is routinely done in other
         reconciliation procedures. Customary business records may be used for
         this purpose.

                  Company will verify, using THPR's (readily retrievable)
         customary business records, that a tracking system exists which will
         ensure that any Hemophilia Therapy Goods purchased under the Veteran's
         Health Care Act of 1992 are not diverted to individuals who are not
         Approved Patients of Company. Such records may include: prescription
         files, velocity reports, and records of ordering and receipt. These
         records will be maintained for the period of time required by State law
         and regulations.

                  Prior to THPR providing pharmacy services pursuant to this
         Agreement, Company will have the opportunity, upon reasonable notice
         and during business hours, to examine the tracking system. Company will
         establish a process for a periodic random (sample) comparison of its
         prescribing

                                       15

<PAGE>

         records with THPR's dispensing records to detect potential
         irregularities. THPR will permit Company or its duly authorized
         representatives to have reasonable access to THPR's facilities and
         records during the term of this Agreement in order to make periodic
         checks regarding the efficacy of such tracking systems. THPR agrees to
         make any and all adjustments to the tracking system which Company
         advises are reasonably necessary to prevent diversion of the Hemophilia
         Therapy Goods to individuals who are not Approved Patients of the
         Company.

         I. Handling and Labeling. THPR agrees that all Hemophilia Therapy Goods
         provided by Company shall be labeled in accordance with applicable
         Federal, State and local law and that said Hemophilia Therapy Goods
         shall be stored, shipped and handled by THPR in accordance with
         recognized professional standards for handling and storage of such
         products and in accordance with Company's policies and procedures to
         the extent that same do not contradict the requirements of Federal,
         State and local law. As part of preparing Hemophilia Therapy Goods for
         shipment, THPR shall pack the goods in cartons or other suitable
         packaging with such cooling packs, insulation, or other packing
         materials as necessary. All Hemophilia Therapy Goods shall be 
         delivered to Company's patients on behalf of Company, by Federal 
         Express or other acceptable courier, with the cost of said 

                                       16

<PAGE>

         delivery to be paid by THPR.

         J. Other Services. Regardless of the fact that THPR has agreed in this
         Agreement to provide services other than Contract Pharmacy Services to
         Company, access to 340B pricing will always be restricted to only
         Approved Patients of the Company.

         III. Compensation. In exchange for the services provided by THPR under
Sections IIA through IIJ of this Agreement, the Company agrees to pay THPR a
monthly fee as set out on Exhibit B. Said fee shall be determined on a monthly
basis by THPR and THPR shall at the end of each calendar month during the term
of this Agreement submit invoices to the Company setting out the amounts due
THPR for said month. The invoices for THPR's services shall be due and payable
* (*) days from the receipt of same by the Company, except that the first
months invoice will be due in * (*) days. Both parties acknowledge and
agree that the fees established for the Contracted Pharmacy Services have been
set in advance, are consistent with fair market value derived in an arms-length
transaction, and have not been determined in a manner that takes into account
the volume or value of any referrals or business otherwise generated between the
parties.

         IV. Company Costs. It is agreed and understood that during the term of
this Agreement, THPR shall be responsible for the 

                                       17

<PAGE>

costs incurred in providing the services which it is obligated to provide
hereunder, and that THPR shall pay such costs out of its compensation received
under Section III. Notwithstanding the preceding provision, the Company shall be
responsible for the costs of salaries and fringe benefits for the Company's
employees, if any; cost of goods; outside auditor fees; interest expense; state
taxes; principal on Company loans; depreciation; and payroll taxes for its
employees, if any, and the cost of preparing the Company's Federal and State
Income tax returns. All such expenses shall be contracted for and in the name of
the Company, based solely upon the Company's credit, and THPR shall not be
liable to third party providers for the costs of such goods and services.

         V. Subcontracting. The parties to this Agreement recognize that THPR
may provide to the Company certain of the goods and services which it is
obligated to provide under this Agreement by means of subcontracts with third
parties, provided however that the use of subcontractors shall not relieve THPR
of its obligations hereunder.

         VI. Indemnity and Insurance. THPR and Company hereby agree that:

         A. THPR shall assume responsibility for and shall indemnify and hold
         Company harmless and defend Company from all losses (including claims
         for injuries to employees of THPR or of Company), expenses, attorneys'
         fees, damages, 

                                       18

<PAGE>

         claims and judgments awarded to third parties resulting solely from
         the negligent acts or omissions or wrongful acts of THPR, its agents
         or employees;

         B. Company shall assume responsibility for and shall indemnify and hold
         THPR harmless and defend THPR from all losses (including claims for
         injuries to employees of THPR or of Company), expenses, attorneys'
         fees, damages, claims and judgments awarded to third parties resulting
         solely from the negligent acts or omissions or wrongful acts of
         Company, its agents or employees.

         The indemnities and assumptions of liabilities and obligations herein
provided for shall continue in full force and effect notwithstanding the
termination of this Agreement whether by expiration of time, by operation of law
or otherwise. Each party hereto agrees to reimburse the other party for its
attorneys fees incurred in enforcing the provisions of this Agreement. This
obligation shall only apply when the party seeking to recover attorneys fees has
obtained a final non-appealable judgment from a court of competent jurisdiction
holding that a breach of this Agreement has occurred and awarding dollar damages
as a result of said breach. THPR, during the term of this Agreement, will
provide through a related entity at its sole cost and expense, general public
liability, products liability and property damage insurance in limits of not
less than $1,000,000.00 per incident; 

                                       19

<PAGE>

and $3,000,000.00 per annum aggregate. All policies insuring against liability
for bodily injury or death or damage to property shall include coverage for
malpractice if such exposure exists and shall insure THPR against the matters
covered by THPR's contractual duty to indemnify the Company set out hereinabove.

         THPR will provide Company with certificates evidencing the insurance
required hereunder, and all such policies shall provide that notice of
cancellation or termination thereof shall be provided in advance to Company. In
the event of cancellation or termination of the coverage described herein, THPR
shall immediately obtain substitute or replacement coverage.

         VII. Term. This Agreement shall be for a term beginning on the date of
the execution hereof and expiring on March 31, 1999, unless otherwise terminated
in accordance with this section. This Agreement shall automatically terminate
upon (a) THPR or the Company ceasing to exist or upon either party ceasing to be
licensed to sell Hemophilia Therapy Goods or upon either party permanently
ceasing to engage in the Hemophilia Therapy Business, (b) the mutual agreement
of the parties, (c) upon notice by either party hereto given twelve months prior
to the effective date of termination, (d) upon the insolvency or bankruptcy of
either party, the making by either party of an assignment for the benefit of
creditors, the consent by either party to the appointment of a trustee or
receiver, or the appointment without its consent, of a 

                                       20

<PAGE>

trustee or receiver, for it or for a substantial part of its property, or (e)
the institution by or against either party of bankruptcy, reorganization,
arrangement or insolvency proceedings.

 In addition, if either party hereto shall breach the terms of this Agreement,
the nonbreaching party may give written notice of the breach to the breaching
party, and if said breach is not cured within fourteen (14) business days
following the giving of said notice, this Agreement shall at the option of the
nonbreaching party be terminated. Notwithstanding the above, this Agreement
shall be terminated immediately in the event that Company loses its status as a
Covered Entity as defined herein, or if any federal or state law is enacted
which could make this Agreement impractical including, but not limited to, a law
which limits the Company's ability to bill third party payors in excess of the
Company's acquisition cost plus a dispensing fee for outpatient drugs purchased
under Section 340B of the Public Health Services Act.

         VIII. Applicable Patients. This Agreement only applies to individuals
who are patients of the Company and who are covered under the Chronically Ill
and Disabled Children's Services Program or Medicare or who pay with private
insurance or personal funds. This Agreement does not apply to patients who are
covered under the state Medicaid program.

         IX. Force Majeure. The obligations of THPR hereunder shall 

                                       21

<PAGE>

be excused during any period of delay caused by matters such as strikes, acts of
God, shortages of raw materials or power, governmental action or compliance with
governmental requirements, whether voluntary or pursuant to order, or any other
matter which is beyond the reasonable efforts of THPR to control.

         X. Independent Contractor. It is agreed that THPR shall be an
independent contractor, and not an employee of the Company.

 THPR shall have sole control and discretion in the manner of performing its
obligations under this Agreement and the Company shall not be responsible for
the acts of THPR while THPR is performing services under this Agreement. THPR is
solely responsible for its employees' salaries, federal and state income
withholding, social security tax withholding, workmen's compensation benefits
and fringe benefits.

         XI. Severability. If any one or more of the provisions of this
Agreement shall for any reason be held illegal or invalid, such illegality or
invalidity shall not affect any other provision of this Agreement and this
Agreement shall be enforced as if such illegal or invalid provision had not been
contained herein.

         XII. Confidentiality. Each party has developed or may during the term
hereof develop certain products, methods of doing business, customer lists and
other proprietary information which that party deems to be confidential and a
trade secret. In the 

                                       22

<PAGE>

course of fulfilling their respective obligations hereunder, some of these
products, methods and other proprietary information will become known to the
other party hereto. Each party agrees that it will not duplicate, make use of,
or disclose, in any manner whatsoever, any information which is deemed to be
confidential by the other party, either during or after the term of this
Agreement, without the express prior written consent of the other party hereto.

         In the event that any information deemed to be confidential by a party
is provided to the other party or its employees or agents in writing, the party
providing same shall mark the writing as "confidential." In the event that such
information is provided in non-written form such as orally, by audiotape,
videotape or computer software or disc, the party claiming such information to
be confidential shall furnish to the other party a written list containing a
brief description of such item and designating such item as confidential. Upon
termination of this Agreement, all copies of any information hereunder deemed,
or designated by a party as, confidential shall be returned to the party who
supplied the information, or who designated same as confidential.
Notwithstanding the preceding provision, the following types of information
provided by a party shall always be deemed confidential, whether or not so
designated: patient records; prescription files; lists of patient names,
addresses or phone

                                       23

<PAGE>

numbers; lists of referring practitioner names, addresses or phone numbers;
costs of goods and supplies; and financial records of the party.

         It is recognized and acknowledged that damages caused by a party's
breach of this Section would be difficult to ascertain and would not adequately
compensate the other party for its losses. Therefore, both parties agree that
the party claiming a breach of this Section shall be entitled to injunctive
relief to restrain the commission or continued commission of said breach by
seeking such relief from a court of competent jurisdiction.

         Notwithstanding the preceding paragraphs, this restriction shall not
apply (a) to any information which is not deemed confidential hereunder, or
which has not been designated as confidential in the manner specified herein,
(b) to any information which was known to a party prior to its disclosure by the
other party, (c) to any information which is or becomes public knowledge through
no failure of a party bound by this Agreement, (d) any information which is
independently developed by a party hereto, or (e) to the extent that such
restrictions conflict with the terms of the Company Agreement evidencing the
Company.

         XIII. Service to Other Businesses. Company acknowledges that THPR
offers its services to other businesses and Company agrees that no provision
contained herein shall restrict or prohibit THPR from providing services to
others in addition to the Company as

                                       24

<PAGE>

long as the performance of said services does not interfere with the performance
of THPR's obligations hereunder.

         XIV. Records. To the extent required by Section 1861(b)(1)(1) of the
Social Security Act, THPR shall, upon proper request, allow the United States
Department of Health and Human Services, the Comptroller General of the United
States and their duly authorized representatives, access to this Agreement and
to all books, documents and records necessary to verify the nature and extent of
the costs of the services provided by THPR under this Agreement at any time
during the term of this Agreement and for an additional period of four (4) years
following the last date services are furnished under this Agreement. Upon
request, a copy of this Agreement will be provided to a participating
manufacturer which sells covered outpatient drugs to Company. All confidential
proprietary information shall be deleted from the Agreement prior to disclosure
to a manufacturer.

         XV. Nonassignability. The rights, duties and responsibilities of the
parties hereto are personal in nature and, except as stated herein, shall not be
assigned without the express written consent of the other party.

         XVI. Applicable Law. This Agreement shall be construed in accordance
with the laws of the State of Tennessee and the laws of the State of Tennessee
shall govern the rights, duties, 

                                       25

<PAGE>

liabilities and responsibilities created hereunder.

         XVII. Compliance With The Law. THPR and Company will adhere to all
Federal, State, and local laws and requirements. Both THPR and the Company are
aware of the potential for civil or criminal penalties if Company and/or THPR
violate Federal or State law.

         XVIII. Headings. All headings under herein are for each of reference
only and shall in no way be construed as interpreting, decreasing or enlarging
the provisions of this Agreement.

         XIX.  Effect.  This Agreement shall be binding upon and shall
inure to the benefit of the parties hereto, their successors,
administrators, trustees and assigns.

         XX. Modification. This Agreement may be changed or modified only with
the written consent of both parties.

         XXI. Notices. All notices, demands, requests, consents, reports,
approvals, or other communications which may be or are required to be given,
served, or sent pursuant to this Agreement shall be in writing and shall be
mailed by first class, registered or certified mail, return receipt requested,
postage prepaid, or transmitted by telegram, addressed as set out below. Each
party may designate by notice in writing a new address to which any notice,
demand, request, consent, report, approval or

                                       26

<PAGE>

communication may thereafter be so given, served or sent. Each notice, demand,
request, consent, report, approval or communication which shall be mailed in the
manner described above, or which shall be delivered to a telegraph company,
shall be deemed sufficiently given, served, sent or received for all purposes at
such time as it is delivered to the addressee (with the return receipt or the
delivery receipt being deemed conclusive evidence of such delivery) or at such
time as delivery is refused by the addressee upon presentation.

         XXII.   Licenses.  THPR is a licensed pharmacy under the laws
of Texas.  THPR agrees to maintain all licenses and permits
necessary to fulfill its obligations hereunder.

         XXIII.  Waivers.  A waiver of the breach of any provision of
this Agreement shall not be deemed a waiver of any other breach of
the same or any other provision hereof.

         XXIV. Provider. Company represents that it does not have access to
appropriate "in-house" pharmacy services as that term is used by the PHS in its
Contracted Pharmacy Service guidelines. Company understands and agrees that THPR
is the provider of Contracted Pharmacy Services to Approved Patients of the
Covered Entity during the term of this Agreement.
