Stock after the date of this Agreement), IDX shall cause any IDX Designee then
serving as a director of Allscripts to resign immediately unless otherwise
requested by Allscripts.

          (b)  The director initially designated by IDX as the IDX Designee is
R.E.T.  Allscripts shall provide IDX with 30 days' prior written notice of any
intended mailing of a notice to stockholders for a meeting at which directors
are to be elected.  IDX shall give written notice to Allscripts, no later than
10 days prior to such mailing, of the Person designated pursuant to Section
2.2(a) as nominee for election as director.  Allscripts agrees to nominate and
recommend for election as director the individual designated, or to be
designated, pursuant to Section 2.2(a).  If IDX shall fail to give notice to
Allscripts as provided above, it shall be deemed that the IDX Designee then
serving as director shall be the IDX Designee for election.

          (c)  Except as otherwise provided herein, at all times (i) when there
is an IDX Designee on Allscripts' Board of Directors and IDX and its Affiliates
shall Beneficially Own 5,623,379 or more shares of Common Stock (subject to
equitable adjustment in the event of any stock split, stock dividend, reverse
stock split or similar event affecting the Allscripts Common Stock after the
date of this Agreement), and (ii) such designee is R.E.T., the IDX Designee
shall be elected as the sole Vice Chairman of the Allscripts Board of Directors,
which shall be a non-executive position.

          (d)  In the event that any IDX Designee shall cease to serve as a
director for any reason (other than as set forth in Section 2.2(a)), the vacancy
resulting thereby shall be filled by the remaining directors of Allscripts in
accordance with its Certificate of Incorporation, Bylaws and applicable law by a
new IDX Designee and such new IDX Designee shall thereafter serve until the
expiration of the term of the IDX Designee replaced by such new IDX Designee.

          (e)  Notwithstanding anything to the contrary contained herein, no IDX
Designee may be a Person who previously has been a director of Allscripts and
was properly removed for cause from the Board of Directors of Allscripts or a
Person who has been convicted of a felony or a crime involving moral turpitude.

          (f)  The IDX Designee will be furnished with all information that is
provided to all other directors of Allscripts (in their capacities as such) at
the same time as such information is furnished to such other directors (in their
capacities as such).

                                       8

          (g)  IDX shall cause the IDX Designee serving as a director of
Allscripts to comply with the retirement policies of Allscripts as in effect on
the date hereof (a copy of which is attached as Exhibit A) or as hereafter
amended or modified from time to time by the Board of Directors of Allscripts or
its stockholders; provided, however, that no such amendment or modification to
such policies shall be binding upon IDX or the IDX Designee unless the IDX
Designee shall have voted in favor of such amendment or modification at the
meeting, or in the action in lieu of a meeting, of the Board of Directors of
Allscripts at or in which it is considered.

          (h)  IDX shall make the initial IDX Designee reasonably available for
initial marketing ("road show") efforts undertaken by Allscripts in connection
with the Merger Agreement and for subsequent meetings with customers of the
Channelhealth business (which shall occur not less frequently than once per
month).

     2.3  LIMITATION ON ACQUISITION OF ADDITIONAL VOTING SHARES BY IDX

          (a)  From and after the date hereof, IDX shall not acquire any
Allscripts Voting Shares, other than the IDX Shares owned by IDX as of the date
hereof and after giving effect to the Closing, (i) without the prior written
consent of a majority of the Allscripts Continuing Directors or (ii) pursuant to
Article III of the Merger Agreement; provided, however, that nothing in this
Section 2.3(a) shall limit IDX's power and right (A) to purchase or acquire
shares as a result of any stock dividend or stock split, reclassification of the
Allscripts Common Stock, or the exercise or conversion of any security received
by IDX from Allscripts in respect of the IDX Shares, or (B) to acquire shares of
Allscripts Common Stock or any Allscripts Exchangeable Security pursuant to
Section 2.6 or to convert, exchange or exercise any such Allscripts Exchangeable
Security.

          (b)  From and after the date hereof, Allscripts shall not acquire any
IDX Voting Shares without the prior written consent of a majority of the IDX
Continuing Directors; provided, however, that nothing in this Section 2.3(b)
shall limit Allscripts' power and right (i) to purchase or acquire shares as a
result of any stock dividend or stock split, reclassification of the IDX Common
Stock, or the exercises or conversion of any security received by Allscripts
from IDX in respect of any IDX securities that Allscripts may hold or (ii) to
acquire shares of IDX Common Stock, or the exercise or conversion of any
security received by Allscripts in respect of any IDX securities that Allscripts
may hold or any IDX Exchangeable Security pursuant to Section 2.6 or to convert,
exchange or exercise any such IDX Exchangeable Security.

          (c)  Notwithstanding anything to the contrary contained herein, in the
event IDX shall effect a sale of any IDX Shares, IDX shall be entitled to
acquire additional Voting Shares, without the necessity of obtaining prior
written consent, up to an aggregate amount that would cause IDX to hold the same
amount of Voting Shares as IDX held after giving effect to the Closing, and the
obligations of Allscripts set forth in Section 2.2 shall be reinstated, if
applicable; provided, however, that (i) IDX may not undertake to acquire such
additional Voting Shares until the end of the six month period immediately
following any such sale, (ii) in no event will IDX be entitled to reinstate the
obligations of Allscripts set forth in Section 2.2(b) once such obligations are
terminated and (iii) IDX will be restricted from making any further sales of IDX

                                       9
<PAGE>

acquisition of any additional Voting Shares pursuant to this Section 2.3(c).

     2.4  RESTRICTIONS ON TRANSFER. From and after the date hereof until the
termination of this Agreement, IDX and its Affiliates shall not sell, transfer,

Voting Shares subject to Allscripts Exchangeable Securities), without the prior
written consent of a majority of the Allscripts Continuing Directors, except
that, in any event, any and all of the following Transfers shall be permitted:

Allscripts (pursuant to a tender offer or otherwise).

          (c)  One or more Transfers pursuant to a merger, consolidation or
compulsory share exchange, in which Allscripts is a constituent corporation.

          (d)  One or more Transfers made as a pro rata dividend or distribution
to the holders of the common stock of IDX or its Affiliates; provided, however,
unless such dividend or distribution is to the public stockholders of IDX, such
holders agree in writing with Allscripts to be bound by the same restrictions as
IDX hereunder.

          (e)  One or more Transfers to any Person (other than IDX or any of its
Affiliates) who shall have commenced a tender or exchange offer for shares of
Allscripts Common Stock if, at the time of public announcement of the tender or

</TABLE>

          *These time restrictions and percentages will also apply
          to any shares of Allscripts Common Stock acquired by IDX
          and its Affiliates pursuant to Article III of the Merger
          Agreement, which will result in additional IDX Shares that
          can be Transferred based on the percentage limitations
          being applied to a greater number of IDX Shares.

In any month, no more than 16.6667% of the IDX Shares eligible to be Transferred
during the then current year may be sold by IDX and its Affiliates pursuant to
this Section 2.4(f). IDX and its Affiliates shall not be permitted to cumulate,
or carry forward for Transfer in subsequent periods, either (i) unsold maximum
monthly eligible share Transfer amounts from month to month during any
particular year or (ii) unsold maximum annual eligible share Transfer amounts
from year to year.

          (g)    Subject to Section 2.4(f), one or more Transfers in accordance
with Rule 144; provided, however, that no Transfers shall be permitted pursuant
to Rule 144 except through one of the market makers in Allscripts' Common Stock
listed on Schedule II or as otherwise previously approved in writing by
Allscripts.

          (h)(i) During each of the periods (A) from and after the first
anniversary of the date hereof through the second anniversary of the date hereof
and (B) from and after the third anniversary of the date hereof through the
fourth anniversary of the date hereof, IDX may deliver a written notice to
Allscripts that IDX desires to Transfer in a single transaction either 50% or
100% of the maximum aggregate number of its IDX Shares that it would be
permitted to Transfer in that period, which notice (the "Notice of Proposed
Transfer") must set forth (A) the number of IDX Shares that IDX desires to
Transfer (which number must equal either 50% or 100% of the maximum aggregate
number of shares that it would be permitted to Transfer in that period) and (B)
the price at which IDX would be willing to Transfer such shares (the "Target
Price"). The Notice of Proposed Transfer shall constitute an offer by IDX, which
shall be irrevocable for a period of 10 days following receipt of such notice by
Allscripts, to permit Allscripts to arrange for the purchase of such shares by a
purchaser selected by Allscripts in its sole discretion for cash at a price per
share equal to the average of the Per Share Market Value of such shares for the
five Trading Days immediately preceding (and excluding) the date that Allscripts
delivers a written notice to IDX (the "Notice of Arranged Transfer") that
Allscripts has arranged for such purchase at such price per share (the "Market
Price"); provided, however, that

                                       11
<PAGE>

IDX shall have no obligation to Transfer any of its IDX Shares to the proposed
purchaser if the proposed purchase price per share does not equal at least 90%
of the Target Price.

               (ii)   The consummation of such purchase shall take place on such
date, not later than 10 days after receipt of the Notice of Arranged Transfer by
IDX, as Allscripts and IDX shall select. Upon the consummation of such purchase,
(A) IDX shall deliver the certificate or certificates evidencing the IDX Shares
so purchased duly endorsed in blank for transfer or accompanied by written
instruments of transfer in form satisfactory to the purchaser duly executed by
IDX, free and clear of any liens, encumbrances and claims and (B) the purchaser
shall simultaneously with the delivery of the certificate or certificates
evidencing the IDX Shares so purchased pay to IDX the aggregate Market Price of
such shares.

               (iii)  Allscripts shall have no obligation to deliver a Notice of
Arranged Transfer in response to any Notice of Proposed Transfer delivered by
IDX, and the decision as to whether to deliver any Notice of Arranged Transfer
shall be made by Allscripts in the exercise of its sole discretion.  In the
event that Allscripts shall have received a Notice of Proposed Transfer from IDX
but shall not have given a Notice of Arranged Transfer to IDX with respect
thereto prior to the expiration of the 10-day period following receipt of such
Notice of Proposed Transfer, nothing in this Section 2.4(h) shall limit the
right of IDX to Transfer any IDX Shares that are not to be purchased pursuant to
a Notice of Arranged Transfer, but otherwise subject to and in accordance with
the time, percentage and other restrictions set forth in Section 2.4(f).

       (i) (i) From and after the fifth anniversary of the date hereof, IDX
agrees not to effect any Transfer of IDX Shares in any single transaction
involving a number of such shares representing in excess of 2.5% of the then
issued and outstanding shares of Allscripts Common Stock unless and until IDX
delivers a written notice to Allscripts that IDX intends to effect such
Transfer, which notice (a "Notice of Block Transfer") must set forth (A) the
number of IDX Shares that IDX desires to Transfer, or maximum and minimum number
of, such shares and (B) the price per share at which IDX would be willing to
Transfer such shares (the "Specified Price"). The Notice of Block Transfer shall
constitute an offer by IDX, which shall be irrevocable for a period of 10 days
following receipt of such notice by Allscripts, to permit Allscripts to arrange
for the purchase of the maximum number (but not fewer than the minimum number)
of such shares by a purchaser selected by Allscripts in its sole discretion for
cash at a price per share equal to the average of the Per Share Market Value of
such shares for the five Trading Days immediately preceding (and excluding) the
date that Allscripts delivers a written notice to IDX (the "Notice of Block
Purchase") that Allscripts has arranged for such purchase at such price per
share (the "Current Price"); provided, however, that IDX shall have no
obligation to Transfer any of its IDX Shares to the proposed purchaser if the
Current Price does not equal at least 90% of the Specified Price offered in the
Notice of Block Transfer.

               (ii)   The consummation of such purchase shall take place on such
date, not later than 10 days after receipt of the Notice of Block Purchase by
IDX , as Allscripts and IDX shall select. Upon the consummation of such
purchase, (A) IDX shall deliver the certificate or certificates evidencing the
IDX Shares so purchased duly endorsed in blank for transfer or accompanied by
written instruments of transfer in form satisfactory to the purchaser duly
executed by IDX, free and clear of any liens, encumbrances and claims and (B)
the purchaser

                                       12
<PAGE>

shall simultaneously with the delivery of the certificate or certificates
evidencing the IDX Shares so purchased pay to IDX the aggregate Current Price of
such shares.

               (iii)  Allscripts shall have no obligation to deliver a Notice of
Block Purchase in response to any Notice of Block Transfer delivered by IDX, and
the decision as to whether to deliver any Notice of Block Purchase shall be made
by Allscripts in the exercise of its sole discretion.  In the event that
Allscripts shall have received a Notice of Block Transfer from IDX but shall not
have given a Notice of Block Purchase to IDX with respect thereto prior to the
expiration of the 10-day period following receipt of such Notice of Block
Transfer, nothing in this Section 2.4(i) shall limit the right of IDX to
Transfer any IDX Shares that are not to be purchased pursuant to a Notice of
Block Purchase.

       (j) (i) During the period from and after the third anniversary of the
date hereof through the fourth anniversary of the date hereof, if Allscripts
proposes to file a registration statement under the Securities Act with respect
to a primary firm commitment underwritten public offering of Allscripts Common
Stock (a "Piggyback Registration"), it shall give written notice of such
proposed filing to IDX as soon as practicable, but in no event fewer than 20
days before the anticipated filing date. Allscripts shall include in such
registration all IDX Shares with respect to which Allscripts has received a
written request for inclusion within 10 days after the giving of Allscripts'
notice (a "Piggyback Registration Request"); provided, however, that Allscripts
may in its sole discretion restrict the number of IDX Shares so requested for
inclusion to the maximum aggregate number of such shares that IDX would be
permitted to sell in such period after the date that Allscripts gives notice of
its intention to effect a Piggyback Registration.

               (ii)   If the managing underwriters of the Piggyback Registration
advise IDX that, in their opinion, the number of shares requested to be included
in such registration exceeds the maximum number that can be included in such
offering without adversely affecting the marketability of the offering (the
"Maximum Number"), IDX will limit the number of shares included in such
registration to the Maximum Number, and the shares registered shall be selected
in the following order of priority: (A) first, the shares of Allscripts Common
Stock Allscripts proposes to Transfer, and (B) second, the IDX Shares covered by
the Piggyback Registration Request and other shares requested to be included in
such registration based upon rights under agreements outstanding on the date
hereof; provided, however, that if shares of Common Stock are being offered for
the account of Persons other than IDX, the proportion by which the amount of IDX
Shares intended to be offered for the account of IDX is reduced shall not exceed
the proportion by which the amount of shares of Allscripts Common Stock intended
to be offered for the account of such other Persons is reduced.

               (iii)  IDX may not participate in any Piggyback Registration
unless it (A) agrees to sell its shares of Allscripts Common Stock on the basis
provided in any underwriting arrangements approved by Allscripts, (B) completes
and executes all questionnaires, powers of attorney, custody arrangements,
indemnities, underwriting agreements and other documents reasonably required
under the terms of such underwriting arrangements and this Agreement, and (C)
furnishes in writing to Allscripts such information regarding IDX and other
information as Allscripts may from time to time request or as may be legally
required in connection with such registration; provided, however, that IDX shall
not be required to make any

                                       13
<PAGE>

representations or warranties in connection with any such registration other
than representations and warranties as to (x) its ownership of its IDX Shares to
be Transferred free and clear of all liens, encumbrances and claims, (y) IDX's
power and authority to effect such Transfer, and (z) such matters pertaining to
compliance with securities laws as may be reasonably requested; provided
further, however, that the obligation of IDX to indemnify pursuant to any such
underwriting agreements shall be several, not joint and several, among such
Persons selling securities, and the liability of IDX will be in proportion to,
and provided further that such liability will be limited to, the net amount
received by IDX from the sale of the IDX Shares pursuant to such registration.

               (iv)  In connection with any Piggyback Registration, Allscripts
will enter into such agreements (including an underwriting agreement) as are
customary in transactions of the kind contemplated by the intended method or
methods of distribution set forth in the Piggyback Registration Statement and
reasonably acceptable to Allscripts, and take such other actions as are
reasonably necessary in connection therewith in order to expedite or facilitate
the Piggyback Registration; and (A) make such representations and warranties
with respect to the Piggyback Registration Statement or any post-effective
amendment or supplement thereto, prospectus or any amendment or supplement
thereto, and documents incorporated by reference, if any, to IDX and the
underwriters of the Piggyback Registration in form, substance, and scope as are
customary in connection with transactions of such kind; (B) if requested by the
managing underwriters of the Piggyback Registration, obtain an opinion of
outside counsel to Allscripts in customary form and covering matters of the type
customarily covered by such an opinion, addressed to such underwriters named in
the underwriting agreement and dated the date of the closing of the sale of the
shares covered by the Piggyback Registration Statement; (C) if requested by the
managing underwriters of the Piggyback Registration, obtain a "comfort" letter
(or, if a "comfort" letter may not be delivered under applicable accounting
pronouncements or standards, a single "procedures" letter) and a single update
thereof from each of the independent certified public accountants who have
certified the most recent audited financial statements that are incorporated by
reference in the Piggyback Registration Statement, which letters shall be
addressed to the underwriters of the Piggyback Registration, such letter or
letters to be in customary form and covering such matters of the type
customarily covered by "comfort" letters of such type; (D) deliver such
documents and certificates as may be reasonably requested by IDX and the
underwriters of the Piggyback Registration to evidence compliance with any
conditions contained in the underwriting agreement or other agreements entered
into by Allscripts; and (E) undertake such obligations relating to expense
reimbursement as provided in Section 2.4(j)(v) and indemnification and
contribution obligations for the benefit of IDX of the type customarily
undertaken by issuers in connection with "piggyback" registrations.

               (v)   In connection with any Piggyback Registration, Allscripts
agrees to bear and to pay, or cause to be paid, promptly upon request being made
therefor, all expenses incident to Allscripts' performance of, or compliance
with, this Section 2.4(j), including, without limitation: (A) all SEC and any
National Association of Securities Dealers registration and filing fees and
expenses, (B) all fees and expenses in connection with the qualification of the
shares covered by any Piggyback Registration Statement for offering and sale
under state securities or "blue sky" laws, including reasonable fees and
disbursements of counsel for any underwriter in connection with such
qualifications, (C) all expenses relating to the preparation, printing,
distribution and reproduction of any Piggyback Registration Statement, each
prospectus included

                                       14

such Piggyback Registration Statement and all other documents relating hereto,
(D) internal expenses of Allscripts, including, without limitation, all salaries
and expenses of Allscripts' officers and employees performing legal or
accounting duties, (E) fees, disbursements and expenses of Allscripts' counsel
and its other advisors and experts and independent certified public accountants
of Allscripts (including the expenses of any opinions or "comfort" letters
required by or incident to such performance and compliance) and (F) the fees and
expenses incurred in connection with the listing of the shares covered by the
Piggyback Registration Statement on the Nasdaq Stock Market, Inc. or any other
stock exchange or dealer quotation system on which the Allscripts Common Stock
shall at such time be listed or traded (collectively, the "Expenses"). To the
extent that any Expenses are incurred, assumed or paid by IDX or any underwriter
of shares covered by the Piggyback Registration Statement, Allscripts shall
reimburse IDX for the full amount of the Expenses so incurred, assumed or paid
promptly after receipt of a written request therefor, which shall specify in
reasonable detail the nature and amount of the Expenses. Notwithstanding the
foregoing, IDX shall pay, or cause to be paid, as appropriate, (A) all
underwriting discounts and commissions attributable to the sale of the shares
covered by the Piggyback Registration Statement by or on behalf of IDX, (B) the
fees, disbursements and expenses of its counsel in connection with the offering

     2.5  VOTING OF IDX SHARES.  Except as provided below, during the term of
this Agreement, IDX and its Affiliates shall be entitled to vote on all matters
all of its or their IDX Shares in its or their complete discretion.
Notwithstanding the foregoing, IDX and its Affiliates shall vote all such shares
in accordance with the recommendation of the majority of the Allscripts
Continuing Directors on any matter that (i) constitutes an Allscripts Business
Combination Transaction, (ii) would involve a change of control of Allscripts
(for purposes of this section a change in control shall mean the acquisition by
a Person other than IDX or its Affiliates of Beneficial Ownership of more than
50% of the then outstanding Allscripts Voting Shares), (iii) involves the
issuance by Allscripts of securities for its own account for cash, or (iv)
involves any acquisition by Allscripts, whether through merger, share exchange,
purchase of assets or otherwise unless (A) the average of the Per Share Market
Value for Allscripts' Common Stock for the 90 Trading Days immediately preceding
(and excluding) the date on which the matter is voted upon is less than $14.5625
per share (such amount to be appropriately adjusted to give effect to stock
splits, reverse splits, stock dividends, reclassifications and share exchanges
since the date hereof) and (B) there shall exist no continuing and uncured
default by IDX of any of its obligations under this Agreement, the Merger
Agreement, the Strategic Alliance Agreement, the Facilities Lease Agreement or
the Cross License Agreement (as such terms are defined in the Merger Agreement),
which default shall have resulted in a material adverse effect on the business,
properties, results of operations, prospects, condition (financial or otherwise)
or Per Share Market Value of Allscripts' Common Stock in which case, if both
conditions described in subclauses (A) and (B) are satisfied, IDX and its
Affiliates shall be entitled to vote on each matter described in the foregoing
clauses (i) through (iv) all of its or their IDX Shares in its or their complete
discretion.

     2.6  RIGHT TO PARTICIPATE IN CERTAIN ISSUANCES BY ALLSCRIPTS.

          (a)  If, when, and for so long as, IDX and its Affiliates Beneficially
Own shares of Allscripts Common Stock that would constitute, after giving effect
to the proposed transaction (but not prior to the proposed transaction), less
than the Applicable Percentage of the then outstanding shares of Allscripts
Common Stock, Allscripts shall not issue any shares of Allscripts Common Stock
or any Allscripts Exchangeable Securities, for any consideration or in any type
of transaction, unless Allscripts shall have first complied with, in the case of
an issuance other than pursuant to a Public Offering, the provisions of Section
2.6(b) or, in the case of a Public Offering, the provisions of Section 2.6(c).

          (b)  If Allscripts determines to issue any shares of Allscripts Common
Stock or any Allscripts Exchangeable Security, other than in a Public Offering,
then Allscripts shall provide written notice of such determination to IDX, which
notice shall include all the terms of such issuance and shall offer to IDX the
right to purchase, at the same price and on the same terms as Allscripts
proposes to issue such shares of Allscripts Common Stock or Allscripts
Exchangeable Security to others (or, if Allscripts proposes to issue such shares
of Allscripts Common Stock or any Allscripts Exchangeable Security other than
for cash, at a cash price equal to the current market price of the Allscripts
Common Stock or if an Allscripts Exchangeable Security, such value to be
determined by agreement between Allscripts or IDX, or if the parties are unable
to agree, by an investment banking firm or other asset valuation firm of
national reputation selected by IDX from Schedule I attached hereto (as such
Schedule I may be amended in writing from time to time by both Allscripts and
IDX) with the consent of a majority of the Allscripts Continuing Directors,
which consent shall not be unreasonably withheld, the cost of which shall be
borne by Allscripts) a number or amount of the shares of Allscripts Common Stock
or Allscripts Exchangeable Securities proposed to be issued determined by
dividing the aggregate number of outstanding shares of Allscripts Common Stock
then Beneficially Owned by IDX by the total number of shares of Allscripts
Common Stock then outstanding (the "Offer Notice"). If IDX determines to accept
the offer contained in the Offer Notice, IDX shall deliver a written notice to
Allscripts indicating its acceptance within 10 days after its receipt of the
Offer Notice, which notice shall indicate whether IDX has accepted such offer in
whole or in part, and, if accepted in part, the number or amount of shares of
Allscripts Common Stock or Allscripts Exchangeable Securities as to which such

     placement agent(s), at the applicable offering price, a number or amount of
     the Allscripts Voting Shares, Allscripts Exchangeable Securities or other
     securities proposed to be issued that, if purchased by IDX, would permit
     IDX and its Affiliates to Beneficially Own a number of Voting Shares
     determined by dividing the aggregate number of outstanding shares of
     Allscripts Common Stock then Beneficially Owned by IDX by the total number
     of shares of Allscripts Common Stock then outstanding.

                                                      -----------------
          injuries to or deaths of persons or loss of or damage to property
          arising out of: (i) the Indemnifying Party's products or services as
          marketed by the Indemnified Parties, unless the Indemnified Parties
          shall have acted outside the scope of their rights under this
          Agreement; and (ii) the Indemnifying Party's performance or willful
          misconduct of the Indemnifying Party, its employees, officers, or
          agents in connection with the Indemnifying Party's performance of this
          Agreement, except to the extent caused by the negligence of any
          Indemnified Party.

          11.7.1    The Indemnifying Party's obligations under this Section 12
                    will survive the termination of this Agreement.

          11.7.2    Each Indemnified Party shall give an Indemnifying Party
                    prompt written notice of any Third Party Claim of which such
                    Indemnified Party has knowledge concerning any Losses as to
                    which such Indemnified Party may request indemnification
                    hereunder. If the Indemnifying Party acknowledges in writing
                    its obligation to indemnify the Indemnified Party hereunder
                    against any Losses that may result from such Third Party
                    Claim, then the Indemnifying Party shall be entitled to
                    assume and control the defense of such Third Party Claim at
                    its expense and through counsel of its choice if it gives
                    notice of its intention to do so to the Indemnified Party
                    within five (5) days of the receipt of such notice from the
                    Indemnified Party; provided, however, that if there exists
                                       --------  -------
                    or is reasonably likely to exist a conflict of interest that
                    would make it inappropriate in the judgment of the
                    Indemnified Party, in its sole and absolute discretion, for
                    the same counsel to represent both the Indemnified Party and
                    the Indemnifying Party, then the Indemnified Party shall be
                    entitled to retain its own counsel, at the expense of the
                    Indemnifying Party.  In the event the Indemnifying Party
                    exercises the right to undertake any such defense against
                    any such Third Party Claim as provided above, the
                    Indemnified Party shall cooperate with the Indemnifying
                    Party in such defense and make available to the Indemnifying
                    Party, at the Indemnifying Party's expense, all witnesses,
                    pertinent records, materials and information in the

                                       20
<PAGE>

                    Indemnified Party's possession or under the Indemnified
                    Party's control relating thereto as is reasonably required
                    by the Indemnifying Party.  Similarly, in the event the
                    Indemnified Party is, directly or indirectly, conducting the
                    defense against any such Third Party Claim, the Indemnifying
                    Party shall cooperate with the Indemnified Party in such
                    defense and make available to the Indemnified Party, at the
                    Indemnified Party's expense, all such witnesses, records,
                    materials and information in the Indemnifying Party's
                    possession or under the Indemnifying Party's control
                    relating thereto as is reasonably required by the
                    Indemnified Party.  No such Third Party Claim may be settled
                    by the Indemnifying Party without the prior written consent
                    of the Indemnified Party.

          11.7.3    In no event shall the Indemnifying Party be liable to an
                    Indemnified Party for any indirect, incidental, special,
                    punitive, exemplary or consequential damages arising out of
                    or otherwise relating to this Agreement, even if the
                    Indemnifying Party has been advised of the possibility or
                    likelihood of such damages.

          11.7.4    Notwithstanding the foregoing, with respect to any claim
                    that would otherwise be subject to indemnification by a
                    party pursuant to this Agreement, if indemnification with
                    respect to such claim is governed by the License Agreement,
                    then no indemnification shall be available under this
                    Agreement.

     11.8  Expenses.  Except as otherwise specified in this Agreement, all
           --------

           disbursements of counsel, financial advisors and accountants,
