Item 2.  Acquisition or Disposition of Assets
         ------------------------------------

     On October 30, 1996, Polaroid Corporation (the "Company") announced the
     sale, which was completed on November 26, 1996, of its Helios medical
     diagnostic imaging equipment product line to Sterling Dry Imaging Systems,
     Inc. ("SDIS"), a new subsidiary of SDI Holding Corp. ("Sterling").  The
     Company is also acquiring a minority investment in Sterling and SDIS.
     Earlier in 1996, Sterling, through another subsidiary, acquired the
     medical diagnostic imaging business of E.I. du Pont de Nemours, therefore
     the Helios transaction constitutes a product line extension by Sterling.
     
     In connection with the Helios sale, the Company received a cash payment of
     $29.5 million and 10% of the Common Stock of SDIS.  The Company retains
     the Helios film product line and has entered into a long-term requirements
     contract to manufacture and supply Helios medical diagnostic film
     exclusively to SDIS.  The Company and SDIS have also entered into a laser
     diode supply agreement, a technology research and development agreement
     and related arrangements intended to support SDIS in developing and
     expanding the Helios medical diagnostic imaging equipment product line.
     The Company has also agreed to a non-competition restriction.  The Company
     expects to record a pre-tax charge of $25.0 million  in the fourth quarter
     of 1996 for severance, inventory and fixed assets write offs and other
     costs related to the Helios transaction.
     
     As part of this transaction, the Company is investing $35.0 million ($20.0
     million at closing and $15.0 million after one year) in SDIS 12.5 %
     preferred stock (nonvoting).  The SDIS preferred stock will begin to
     accrue dividends, which may be in the form of further shares of such
     preferred stock, when SDIS accumulates $15.0 million of tangible net worth
     as determined on a GAAP basis.  The SDIS preferred stock does not have a
     scheduled redemption date.  While the Company believes SDIS currently has
     limited common equity, the ultimate value of SDIS stock will depend on its
     future results.
     
     Further, the Company is also purchasing 50,000 shares of Sterling
     Convertible Preferred Stock (convertible into 50,000 shares of Sterling
     Common Stock) at a cost of $150 per share.  The Company has also been
     granted the right to purchase a total of 25,000 shares of Sterling Common
     Stock (which it intends to exercise) at a cost of $250 per share from
     Sterling and Sterling stockholders.
     
     The Company believes the potential value of these transactions will be
     primarily reflected in its equity in Sterling and SDIS, which are
     privately owned companies, rather than through the sale of Helios film
     under the film supply contract.

Item 5.  Other Events
         ------------

     In addition to the disposition of the assets of Helios, the Company
     expects to record a pre-tax charge of approximately $15.0 million in the
     fourth quarter of 1996 to write down parts and capital equipment under
     development for a printer project and other costs.  The Company has
     shifted its strategy relating to the development of desktop printers
     for the home and office market to emphasize alliances with leading
     printer manufacturers.  An example of this new approach was the Company's
     announcement on September 5, 1996 of an alliance with Lexmark
     International Inc. to pursue joint marketing and development of
     color image printers and consumables for the home and office on 
     a worldwide basis.



Item 7.  Financial Statements, Pro Forma Financial Information and Exhibits
         ------------------------------------------------------------------

     (b)  Pro Forma Financial Information
          ------------------------------
       The following unaudited pro forma condensed consolidated financial
       information with respect to the disposition of the Company's Helios
       medical diagnostic imaging equipment product line should be read in
       conjunction with historical financial statements contained in the
       Company's Fiscal 1995 Annual Report on Form 10-K; and the Quarterly
       Report on Form 10-Q for the quarter ended  September 29, 1996.  The
       following pro forma information is presented for illustrative purposes
       only and is not necessarily indicative of the operating results or
       financial position that would have occurred had the disposition of the
       Company's Helios medical diagnostic imaging equipment product line been
       consummated in accordance with the assumptions set forth below, nor is
       it necessarily indicative of future operating results or financial
       position.
       
       Basis of Presentation
       ---------------------
       The unaudited pro forma condensed consolidated balance sheet presents
       the Company's consolidated financial position assuming that the
       disposition of the Helios medical diagnostic imaging equipment product
       line occurred on September 29, 1996.  The unaudited pro forma condensed
       consolidated statements of earnings for the year ended December 31,
       1995 and for the nine months ended September 29, 1996 present the
       Company's consolidated results of operations assuming that the
       disposition of the Company's Helios medical diagnostic imaging
       equipment product line occurred as of January 1, 1995.  The disposition
       of the Company's Helios medical diagnostic imaging equipment product
       line was completed on November 26, 1996.  The unaudited pro forma
       condensed consolidated statements of earnings do not include the effect
       of the nonrecurring pre-tax charge of $25.0 million related to the
       Helios transaction.

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

     Subject to the terms and conditions of this Agreement, in
consideration of the sale, conveyance, assignment, transfer and delivery by
Seller and its Subsidiaries, of the Assets to Buyer, Buyer, Sterling,
Parent and Seller agree as follows:

     3.1  Assumption of Liabilities.  Except as provided in Section 3.02,
Buyer shall assume and agree to pay, discharge and perform when due all
obligations (whether known or unknown, fixed or contingent) to the extent
(but only to the extent) that they relate to events or conditions arising
after the Closing under the Contracts assigned by Seller or its
Subsidiaries to Buyer in accordance with this Agreement (the "Assumed
Liabilities"), including, but not limited to, (i) obligations to sell
products and equipment under such Contracts, (ii) warranty obligations
under such Contracts with respect to goods sold or services rendered under
such Contracts, and (iii) obligations to service equipment purchased or
leased from Buyer after the Closing Date, unless a Contract is terminated
by the other party thereto due to an improper assignment by Seller;
provided that, upon receipt of an invoice from Buyer, Seller shall promptly
reimburse Buyer or its Affiliates for all costs and expenses incurred by
Buyer or Buyer's Affiliates in performing the obligations set forth in
subsections (ii) and (iii) above with respect to Laser Imagers and Laser
Film sold by Seller prior to the Closing Date.

     3.2  Excluded Liabilities. Except for the Assumed Liabilities, neither
Buyer, Sterling nor Parent shall assume or be responsible for any
liabilities or obligations (whether known or unknown, fixed or contingent)
of Seller or of any of its Subsidiaries, or of any prior owner or operator
of any of the Assets, the Equipment Product Lines or any other assets or
properties owned, operated or maintained by Seller or any of its
Subsidiaries (such liabilities and obligations being sometimes referred to
herein as the "Excluded Liabilities").

     3.3  Purchase Price.

          (a)  The aggregate purchase price (the "Purchase Price") for the
Assets (and for the covenant not to compete provided in Section 13.05) and
for all other rights and obligations contemplated hereunder shall be the
aggregate of the following and shall be subject to adjustment as provided
in Section 3.08:  (i) 111 shares of common stock, $.01 par value, of Buyer
(the "Buyer Common Stock"), (ii) cash in the amount of the Inventory Value,

(iii) the assumption of the Assumed Liabilities.



                                    -10-
<PAGE>



          (b)  At Closing, subject to pre-closing adjustment as provided in
Section 3.08, Buyer shall deliver to Seller the Buyer Common Stock and cash
in the amount of the Estimated Initial Inventory Value.

          (c)  On or prior to the Closing Date, the Parties shall agree on
a schedule to allocate the Purchase Price among the various categories of
Assets and other rights to be transferred to or otherwise acquired by Buyer
pursuant to this Agreement. Such allocation shall be used by the Parties in
reporting the transactions contemplated by this Agreement for all tax
purposes.  No Party shall take any position on any of its tax returns that
is inconsistent with such allocation and each Party shall file U.S.
Internal Revenue Service Form 8594, and equivalent forms in other
countries, if necessary, in a manner consistent with this allocation.

     3.4  Initial Inventory Value.  The Parties have agreed that the
initial Inventory Value as of September 30, 1996, is $31,000,000 (the
"Initial Inventory Value").  The Initial Inventory Value multiplied by 95%
is $29,450,000, and such amount shall be referred to herein as the
"Estimated Initial Inventory Value ".

     3.5  Post-Closing Purchase Price Adjustment.

          (a)  Within 120 days after the Closing Date, Seller shall
prepare, with the assistance of Buyer's employees, and deliver a statement
(the "Preliminary Statement"), as of the Closing Date, updating the Initial
Inventory Value so that it reflects the Inventory Value as of the Closing
Date based only on a roll forward basis from September 30, 1996, with no
changes other than to update the Initial Inventory Value from September 30,
1996, using the identical principles, procedures, estimates, judgments,
pricing and other practices used in determining the Initial Inventory Value
as of September 30, 1996.  Subject to the limitations of Section 3.05(e),
if Buyer has any objections to the Preliminary Statement, Buyer must
deliver to Seller within 30 days after delivery of the Preliminary
Statement (but such delivery shall not be required earlier than 90 days
after Closing) a detailed statement describing such objections thereto (the
"Buyer's Statement").  If a Buyer's Statement is not delivered to Seller
within such time period, the determination of the Inventory Value set forth
in the Preliminary Statement will be final, binding, and non-appealable by
the Parties.  The Parties will negotiate in good faith to resolve any such
objections, but if they do not reach a final resolution within 30 days
after Seller has received the Buyer's Statement, such matter shall be
resolved as provided in Section 3.05(b).  Buyer's representatives shall be
entitled to observe all physical inventories that are conducted in
connection with and/or inspect all work papers,  calculations and documents
related to Seller's  updating of the Initial Inventory Value, and to
inspect all work papers, schedules and other supporting materials relating
to, the preparation of the Preliminary Statement.



                                    -11-
<PAGE>




          (b)  In the event any objections to the Preliminary Statement are
not resolved by Seller and Buyer within the 30 day period following
delivery of the Buyer's Statement pursuant to Section 3.05(a), such
unresolved objections shall be submitted for resolution to an
internationally recognized independent certified public accountant located
in Boston, Massachusetts, or New York, New York, selected by the mutual
agreement of Seller and Buyer within 20 days after the end of such 30 day
period.  If Seller and Buyer are unable to mutually agree upon an
internationally recognized certified public accountant within such 20 day
period, then Seller and Buyer shall each select an internationally
recognized certified public accountant and within five days of their
selection those two accountants shall select a third internationally
recognized certified public accountant located in Boston, Massachusetts, or
New York, New York, which third accountant shall arbitrate the claim in
question.  In such event, each of Seller and Buyer must select its
accountant within 10 days after the end of the 20 day period described
above, and if any Party shall fail to select an accountant within such 10
day period, the accountant selected by the other such Party shall select
another internationally recognized certified public accountant, and such
two accountants shall select the third accountant, all within 20 days after
the end of such 10 day period.  The accountant arbitrating a dispute (as
the sole arbitrator) shall be required to submit its decision to Seller and
Buyer within 30 days of appointment, which decision shall be final and
binding on the Parties and shall constitute an arbitral award that is
final, binding and unappealable and upon which a judgment may be entered by
any court having jurisdiction thereof.  The reasonable fees of the
accountant that settles the claim in question and any accountant selected
by an accountant selected by a Party when the other Party has failed to
select an accountant shall be borne by either or both Seller and Buyer in
inverse proportion to the degree of success of such Party by virtue of said
decision as determined by the accountant settling the claim.  The
reasonable fees of  any other accountant selected by a particular Party
shall be borne by such Party.

          (c)  The Inventory Value, as finally determined in accordance
with Sections 3.05(a) or 3.05(b) is referred to herein as the "Actual
Inventory Value."

          (d)  If the Actual Inventory Value is:

               (i)  less than the Estimated Initial Inventory Value, Seller
     shall deliver to Buyer, within three (3) business days after the date
     on which the Actual Inventory Value is finally determined pursuant to
     Sections 3.05(a) and 3.05(b), in immediately available funds, the
     amount of such deficiency, together with interest thereon from the
     Closing Date through the date of payment, computed at the prime rate
     as announced by Bankers Trust Company as of the Closing Date;

               (ii) greater than the Estimated Initial Inventory Value,
     Buyer shall deliver to Seller, within three business days after the
     date on which the Actual Inventory Value is finally determined
     pursuant to Sections 3.05(a) and 3.05(b), in immediately available
     funds, the amount of such excess, together with interest thereon from
     the Closing Date through the date of payment, computed at the prime
     rate announced by Bankers Trust Company as of the Closing Date.



                                    -12-
<PAGE>




            (e)    Notwithstanding anything in this Agreement to the
contrary, Buyer  objections with respect to the Preliminary Statement shall
be limited to objections regarding the updating of the Initial Inventory
Value.

     3.6    Additional Equity Investments.  Contemporaneously with the
Closing, Seller shall also:

            (a)    Purchase 20,000 shares of preferred stock of Buyer (the
"Buyer Preferred Stock"), $20,000,000 aggregate liquidation value, for
$20,000,000 in cash, having the terms set forth in and pursuant to a
Subscription Agreement substantially in the form attached hereto as Exhibit
A (the "Subscription Agreement"), under which Seller shall also commit to
purchase an additional 15,000 shares of Buyer Preferred Stock, $15,000,000
liquidation value, for $15,000,000 in cash on the first anniversary of the
Closing Date;

            (b)    Purchase 50,000 shares of preferred stock, Series B, of
Parent, convertible into 50,000 shares of common stock of Parent, having
the terms set forth in and pursuant to the Subscription Agreement for $150
per share in cash (the "Parent Preferred Stock");

            (c)    Purchase one share of common stock of Parent for $100
in cash, pursuant to the Subscription Agreement (the "Parent Common
Stock"); and

            (d)    Enter into Option Acquisition Agreements in a form
mutually agreeable to the parties thereto (the "Option Acquisition
Agreements") with certain stockholders of Parent pursuant to which such
stockholders will  agree to deliver or cause to be delivered to Seller
options (the "Parent Stockholder Options") to purchase 25,000 shares of
common stock of Parent for the cash purchase price of $250 per share, on
the terms and conditions set forth in the Option Acquisition Agreements.

     3.7    Sales, Use, Transfer and Similar Taxes and Charges.  Seller
shall bear and pay all sales, use or stamp taxes and any transfer, transfer
gain, documentation, gross receipts, custom duties, value added,
withholding tax, recording, filing and registration fees and other taxes
and charges, as well as all interest and penalties thereon payable upon or
with respect to the sale or transfer of the Assets by Seller to Buyer
pursuant to this Agreement (collectively the "Transfer Charges").
Notwithstanding the foregoing, Buyer or Buyer's Affiliates shall be
required to pay all Transfer Charges for which a refund, recoupment or
credit is available to Buyer or Buyer's Affiliates, and Buyer or Buyer's
Affiliates, as the case may be, shall be entitled to obtain and keep such
refund, recoupment or credit; provided, however, that Seller shall
reimburse Buyer for any Transfer Charges paid by Buyer or its Affiliates
for which a refund, recoupment or credit is available but which is not
recovered or recouped by Buyer or Buyer's Affiliates, as the case may be,
within twelve (12) months of the Closing Date.  If Buyer thereafter
receives a refund, recoupment or credit of all or any portion of any
Transfer Charge for which Seller has reimbursed Buyer, Buyer shall
reimburse Seller in an amount equal to such refund, recoupment or credit.
Subject to the foregoing sentence, to the extent any applicable law or
regulation imposes upon a Party the obligation to pay Transfer Charges to
be borne by a Party pursuant to the preceding sentences and such Transfer
Charges are paid by such other Party, the Party responsible for such
Transfer Charges pursuant to the two preceding sentences shall promptly
reimburse such paying Party therefor upon receipt of such paying Party's
invoice for the amount of such payments.

     3.8    Purchase Price Adjustment.  In the event there shall be an
inaccuracy in any of the representations or warranties of Seller or a
breach by Seller of one or more covenants to be performed by Seller prior
to Closing, which inaccuracy or breach is Material and such inaccuracy or
breach does not constitute a failure of the conditions to Buyer's
obligation to close as set forth in Section 12.02(a), or there shall be a
Material loss or damage to any of the Assets as a result of fire or other
casualty and Seller does not elect to restore such Assets as provided in
Section 8.09, the Parties shall use all reasonable efforts to agree prior
to Closing to a downward adjustment to the Purchase Price in an amount
equal to the decline in value of any of the Assets resulting from such
inaccuracy, breach, loss or damage.  In this regard, the decline in value
shall be on a dollar-for-dollar basis for balance sheet items and, with
respect to other items affecting value, shall be as mutually agreed by the
Parties.  If the Parties are unable to agree on the amount of the Purchase
Price adjustment prior to Closing, and all of the conditions to the
obligations of the Parties to close have been satisfied or waived, the
Parties shall proceed to close the transaction contemplated hereby and the
disagreement regarding the amount of the Purchase Price adjustment shall be
resolved in accordance with the dispute resolution procedure described in
Section 3.05(b), with the 30-day period referred to in the first sentence
thereof beginning on the Closing Date.  Once such disagreement is resolved,
Seller shall then pay to Buyer the amount of such adjustment, if any, with
interest at the rate provided in Section 3.05(d)(i) from the Closing Date
through the date of payment.  Notwithstanding anything herein to the
contrary, no downward adjustment in the Purchase Price shall be made under
this Section 3.08 to the extent that the amount thereof is subject to
adjustment under the Inventory evaluation procedures elsewhere in this
Article 3.

also provide to Buyer, Sterling and Parent such other information regarding
the Equipment Product Lines, the marketing and sale by Seller of Laser
Films and the Assets as may reasonably be requested by Buyer, Sterling  or
Parent.

     8.9    Risk of Loss.  Prior to the Closing and the delivery of
possession of the Assets to Buyer in accordance with this Agreement, all
risk of loss to any of the Assets (whether by casualty or otherwise) shall
be borne by Seller.  In the event that any Material loss or damage to any
of the Assets shall occur prior to the Closing Date as a result of fire or
other casualty, Seller shall give Buyer immediate written notice of such
loss or damage.  If, prior to Closing and the delivery  of possession of
the Assets to Buyer in accordance with this Agreement, there is a Material
casualty loss or casualty damage to any of the Assets, Seller shall have
the right to (a) restore such Assets to the condition immediately prior to
the loss or damage and the Closing shall be adjourned for a reasonable
period to allow Seller to effect the necessary repair or reconstruction or
(b) invoke the provisions of Section 3.08 of this Agreement, which also may
be invoked by Buyer.  Seller covenants, if Seller elects to restore, to
proceed diligently with all repairs hereunder in a workmanlike manner.
Notwithstanding the foregoing, if in order to effect the repairs as
aforesaid, the Closing Date would have to be extended by more than 120
days, as reasonably estimated by Buyer, Buyer shall have the right to
terminate this Agreement by written notice to Seller.

that would make any representation, warranty or statement of Seller
contained herein, in light of the circumstances in which it was made,
misleading in any material respect or (ii) the failure by Seller to satisfy
any covenant in this Agreement.  Buyer, Sterling and/or Parent, as the case
may be, shall notify Seller immediately after becoming aware of  (i) the

and/or Parent to satisfy any covenant in this Agreement.

Buyer, Sterling or Parent, as the case may be, may extend the time for the
performance of any of the obligations or other acts of Seller, Buyer,
Sterling or Parent, respectively.  Any agreement by the Parties to any such
extension or waiver shall be valid if set forth in an instrument in writing
signed on behalf of such Parties by duly authorized officers.

Closing, the Parties will, if necessary, draft separate agreements
governing the transfer by Seller and its Subsidiaries to Buyer and its

                    EMPLOYEE BENEFIT MATTERS
                    ------------------------

     9.1    Offer of Employment.  Seller has provided to Buyer as of the
date hereof a list of employees of Seller associated with the Equipment
Product Lines or any of the Assets setting forth the status of such
employees and their compensation, who will be full-time, active employees
on the Closing Date, including those on temporary leave for jury duty,
family and short-term medical leave, vacation or annual two-week military
duty.  Buyer shall provide to Seller at least 10 days prior to the Closing
Date a list of such employees to whom Buyer or its Affiliates will offer
employment (the "Employee List").  Seller shall use all reasonable efforts
(which does not include the increase in any benefits under any employee
benefit program, plan or arrangement) to cause such employees to accept
Buyer's or its Affiliates' offers of employment.  Reasonable efforts for
the purpose of this Article shall mean communicating the benefits to such
employees and the benefits set forth in this Article to encourage their
employment with the Buyer.  Reasonable efforts shall neither preclude the
Seller from retaining those employees who do not accept employment offers
from the Buyer; nor require the Seller to provide any payment or benefit
which is not set forth in this Agreement.  Prior to any employee's
acceptance or rejection of an offer of employment from the Buyer, Seller
shall not provide any incentive for any employee to remain in the
employment of the Seller. Those employees who accept such offers of
employment and become employees of the Buyer or its Affiliates prior to
February 14, 1997 shall be referred to herein as "Transferred Employees".
Employees listed on the Employee List who as of the Closing Date are on
short term medical leave shall not be deemed Transferred Employees if they
do not report for work within six (6) months of the commencement of such
leave and shall remain the responsibility of Seller.

ERISA) that is maintained by Seller (collectively, the "Seller Welfare
Plans") shall cease to do so and (ii) except as otherwise provided in
Sections 9.03(c), 9.08 and 9.09, such Transferred Employee and dependents
shall commence participation in any "employee welfare benefit plan" (as

Welfare Plans") upon the satisfaction of any eligibility requirements as
set forth in the Buyer Welfare Plan.

payment of claims incurred by eligible Transferred Employees, except as
otherwise provided by this Section 9.  The Seller Welfare Plans shall be

of claims of eligible Transferred Employees and their eligible dependents
for expenses incurred under the Buyer Welfare Plans on or after the date
the Transferred Employee becomes an employee of the Buyer or its
Affiliates, notwithstanding the fact that any such expense may be related
to another expense that was paid or is eligible for payment under the terms
of any of the Seller Welfare Plans or was related to any treatment for any
condition diagnosed or existing prior to the Closing Date.

            (e)    The post-retirement welfare benefits for Transferred

satisfaction of any eligibility requirements set forth in the Buyer Pension
Plans.

     9.5    Workers' Compensation.  With respect to Transferred Employees,

claims of Transferred Employees or employees of Seller arising out of their
employment with Seller including, but not limited to, claims arising out of

     9.7    Wage Reporting.  Buyer and Seller will follow the "standard"
IRS procedure (as outlined in Section 4 of Revenue Procedure 84-77, 1984-2
C.B. 753) with regards to reporting of wages on form W-2 and disposition of
forms W-4 and W-5.  Under the standard procedure, the predecessor performs
all reporting duties for wages and other compensation it pays.  The
successor reports only its own payments of wages and other compensation.
Also,  Transferred Employees must provide the successor employer with new
forms W-4 and W-5 for the current year.  Both the predecessor and successor
must provide the employees with form W-2 by January 31 of the next year.
However, if requested by the employee, the predecessor must furnish the
form W-2 within 30 days of the request or within 30 days after the final
payment of wages, whichever is later.  Additionally, the predecessor must
retain on file all the forms W-4 and W-5 provided by its former employees.

     9.8    Vacation.  Seller shall discharge its liability to any
Transferred Employee for vacation accrued through the date a Transferred
Employee's employment with the Seller terminates.  With respect to a

last day of employment with Seller in the calculation of the amount of
vacation a Transferred Employee has accrued under Buyer's or its
Affiliate's vacation policy.

     9.9    Severance.  Seller shall discharge its liability to any
Transferred Employee for severance  benefits accrued through the date a
Transferred Employee's employment with the Seller terminates.  With respect
to a Transferred Employee, Buyer or its Affiliates shall credit all service
recognized under Seller's severance policy through a Transferred Employee's
last day of employment with Seller in the calculation of the amount of
severance benefit a Transferred Employee has accrued under Buyer's or its
Affiliate's severance policy or program.

     13.5   Non Competition.

            (a)    Except as provided in this Section 13.05, for six years
after the Closing Date neither Seller nor any of its Subsidiaries shall,
directly or indirectly, through equity ownership, contract or otherwise,
engage in any business that competes in any part of the world with the
Business of Parent; provided, however, that neither the foregoing
prohibition nor anything else in this Agreement to the contrary shall
prevent the Seller or any of its Subsidiaries from, (i) manufacturing,
marketing or selling any products or services that are manufactured,
marketed, sold or provided by Seller or any of its Subsidiaries for their
own behalf immediately after the Closing (the "Existing Products") or from
manufacturing, marketing or selling any enhancements or improvements of any
Existing Products that are developed after the Closing Date,  (ii)
acquiring (by merger or otherwise) securities or assets of a business if
the gross revenue of such acquired business that is attributable to a
business that competes in any part of the world with the Business of Parent
constitutes less than 10% of the total gross revenues of such acquired
business (or if greater than 10%, such portion over 10% is disposed of by
Seller within six (6) months after such acquisition), (iii) engaging
anywhere in the world in the activities listed on Schedule 13.05, or (iv)
manufacturing, marketing or selling any product resulting from a technology
with respect to which Buyer has waived its rights pursuant to the
Technology, Research and Development Agreement.

            (b)    The Parties acknowledge and agree that the restrictions
contained in this Section 13.05 are fair and reasonable and necessary to
accomplish the full transfer of the technology and other intangible assets
contemplated hereby and the licensing to Buyer of exclusive rights to
technology and other Intellectual Property Rights.  If, at the time of
enforcement of any provision of this Section 13.05, a court or other
tribunal shall hold that the restrictions therein are unreasonable or
unenforceable under circumstances then existing, the Parties agree that the
maximum period, scope or geographical area reasonable under such
circumstances shall be substituted for the stated period, scope or area.

            (c)    The Parties agree that in the event of any breach by
Seller or any of its Subsidiaries of any of the provisions of this Section
13.05, money damages would be inadequate and Buyer, Sterling and Parent
would have no adequate remedy at law.  Accordingly, notwithstanding
anything to the contrary contained in this Agreement, the Parties agree
that Buyer, Sterling and Parent, or any of them,  shall have the right, in
addition to any other rights and the obligations under this Section 13.05,
to seek an adequate remedy for such breach, not only by an action for
damages but also by an action or actions for specific performance,
injunction and/or other equitable relief in order to enforce or prevent any
violations (whether anticipatory, continuing or future) of the provisions
of this Section 13.05.

     13.6   Buyer Debt.  After the Closing and for so long as Seller owns
any equity interest in the Buyer, Buyer shall not incur any debt for
borrowed money other than (i) pursuant to an working capital line of credit
in an amount up to $30,000,000, which shall contain reasonable and
customary terms and conditions, shall be secured by Buyer's accounts
receivable and inventory, shall provide for borrowings, repayments and
reborrowings from time to time as required in connection with the operation
of Buyer's business, shall be limited in amount to customary percentages of
account receivables and inventory securing such line of credit and shall be
provided by a financial institution or an Affiliate of Buyer, (ii) other
loans or credit facilities to be provided by Affiliates of Buyer in the
discretion of such Affiliates and Buyer, which shall be repaid on a pari
passu basis with cash payments on the Buyer Preferred Stock and (iii) other
loans and credit facilities satisfactory to Buyer and Seller.  To the
extent Buyer's working capital needs exceed $30,000,000, the Parties agree
to meet and discuss in good faith possible modifications to the foregoing
limitations.

     13.7   Confidentiality.

            (a)  In addition to any obligations of confidentiality
pursuant to other agreements between the Parties or Affiliates of the
Parties, without the prior written consent of the other Party, each Party
shall hold in confidence and not disclose to any third party (i) any
confidential information received by it from the other Party, and (ii) the
specific terms, conditions and information contained in this Agreement and
any of the Related Documents (collectively, "Confidential Material").

            (b)    Each Party agrees that it shall only use the
Confidential Material for the purposes of carrying out the transactions
contemplated by this Agreement and the Related Documents.

            (c)    For the purposes of this Agreement, Confidential
Material shall not include information:

               (i)  that is or becomes part of the public domain or is
otherwise generally  available to the public other than through breach of
this Agreement or the Related Documents or through the fault of the
receiving Party;

               (ii)  that is or becomes available to the other Party, from
an unaffiliated source, which source has no obligation of secrecy to either
Party;

               (iii)  that is disclosed (a) in any SEC filing; or (b) that
is required to be disclosed by law or governmental regulation or order or
upon the advice of counsel, provided that the Party disclosing such
information shall give the other parties to this Agreement reasonable
advance notice of such disclosure; or



                                    -45-
<PAGE>



               (iv)  that the Parties mutually agree in writing to
disclose.

            (d)    The foregoing obligation of confidentiality shall be
effective from the date of this Agreement and continuing for a period of
six (6) years following the termination of the last to terminate of this
Agreement or the Related Documents.

            (e)    The Parties agree that in the event of any breach by
either Party of  any of the provisions of this Section 8.01, money damages
would be inadequate and that the non-breaching Party would have no adequate
remedy at law.  Accordingly, notwithstanding anything to the contrary
contained in this Agreement, the Parties agree that the Parties shall have
the right, in addition to any other rights and the obligations under this
Section 8.01, to seek an adequate remedy for such breach, not only by an
action for damages but also by an action or actions for specific
performance, injunction and/or other equitable relief in order to enforce
or prevent any violations (whether anticipatory, continuing or future) of
the provisions of this Section 8.01.

must be made within two years after the Closing Date and claims against
Buyer, Sterling or Parent for breach of any of their representations and
warranties in 5.01(b) and (d)(i), 5.02(b) and 5.03(b) and (d)(i) may be

                                    -46-
<PAGE>



            (b)    Any ongoing claims, actions or demands commenced prior
to expiration of the claim period set forth in Section 15.01(a) for breach
of representation or warranty may be pursued to conclusion and such
representation or warranty shall not expire with respect to such claims
even if final disposition of such matter occurs after the claim period has

the indemnification by an indemnifying Party under Articles 6 or 7 for
breach of a representation or warranty shall be limited to such Losses that
exceed $25,000 on an individual claim for indemnification, and exceed
$250,000 in the aggregate for all claims made for indemnification by the
indemnified Party (the "Indemnifier's Basket").  If the Losses for breaches
of representations or warranties claimed exceed the $250,000 Indemnifier's
Basket, the indemnified Party shall be entitled to recover all the Losses
within the Indemnifier's Basket.  These limitations shall not apply to
indemnification claims that are not claims for breach of a representation
or warranty.

     15.3   Limit.  Buyer, Sterling and Parent shall not be required to
indemnify the Seller Indemnified Parties for breach of a representation or
warranty pursuant to Article 6 and Seller shall not be required to
indemnify the Buyer Indemnified Parties for breach of a representation or
warranty pursuant to Article 7 for Losses which exceed $10,000,000, in the
aggregate, provided that such limitation shall not apply to Losses arising
from breaches of Seller's covenants in Section 13.05, Seller's
indemnification obligations pursuant to Article 14, Excluded Liabilities,
Assumed Liabilities or other indemnification claims that are not claims for
breach of representation or warranty.

     15.4   Not a Release of Other Obligations. Notwithstanding the
limitations in this Article 15, such limits are not intended to terminate
or in any way modify or reduce the obligation of Seller to be responsible
for the payment of all of and performance of all of its obligations
relating to Excluded Liabilities or arising under Seller Related Documents
and the obligations of Buyer, Sterling and Parent to be responsible for the
payment of all of and performance of all of their obligations relating to
Assumed Liabilities or arising under the Buyer Related Documents.

     15.5   Procedure. The Person or entity claiming indemnification
hereunder (the "Indemnified Party") shall give prompt written notice to the
Party against which indemnification is claimed (the "Indemnifying Party")
of each claim for indemnification hereunder specifying that indemnification
is sought pursuant to this Agreement, the amount (to the extent known), and
the nature of and event giving rise to the claim.  In the event such
indemnification claim is the result of a claim by a third party (a "Third
Party Claim"), the Indemnifying Party shall have the right to control, at
the expense of the Indemnifying Party, the defense of any such matter or
its settlement, or the Indemnifying Party may authorize the Indemnified
Party to take over the defense of such matter for the account of and at the
risk of the Indemnifying Party so long as such defense is expeditious.
Failure to give timely notice of a matter which may give rise to an
indemnification claim shall not affect the rights of the Indemnified Party
to collect such claim from the Indemnifying Party except to the extent such
failure to so notify materially adversely affects the Indemnifying Party's
ability to defend the Third Party Claim giving rise to such indemnification
claim.  No Indemnifying Party, in the defense of any Third Party Claim,
shall, except with the consent of the Indemnified Party, which consent
shall not be unreasonably withheld or delayed, consent to entry of any

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

be at liberty to issue a press release or public announcement following
execution and delivery of this Agreement with respect to the transactions
contemplated by this Agreement with the prior written consent of the other

shall consult each other in advance on the form and content of such
releases or announcements.  Notwithstanding the foregoing, a Party may

except in writing, signed by the Parties.

17.4Successors.  No Party shall assign, convey, transfer or otherwise
dispose of all or any portion of its rights and obligations under this

connection herewith without the prior written consent of the other Parties,
which consent shall not be unreasonably withheld; provided,  however, that
at and after the Closing Date, Buyer, Sterling or Parent may assign,
convey, transfer or otherwise dispose (subject to the performance
obligations of Buyer, Sterling or Parent, as the case may be) of all or any
portion of their respective interests in, or their respective rights and
obligations under, this Agreement and such other documents and instruments
to any financial institution (acting on its own behalf or as agent for one
or more financial institutions) financing or refinancing the transactions
contemplated hereby or otherwise extending credit to Buyer or any of its
Affiliates; and provided further, that upon the foreclosure, sale in lieu
of foreclosure, deed in lieu of foreclosure, or deed of the Assets or a
substantial portion thereof by or to any such financial institution, any of

<PAGE>


performance of all obligations of Buyer, Sterling  or Parent, as the case
may be) and subject to any defense, estoppel, waiver, setoff or claim which
Seller may have with respect to Buyer, Sterling or Parent (arising before
or after such assignment or foreclosure)).  Any assignment, conveyance,
transfer or other disposition made or attempted in violation of this
Section 17.04 shall be void and of no effect.  Notwithstanding an
assignment by Buyer, Parent or Sterling of all or any portion of their
respective interests in, or their respective rights and obligations under,
this Agreement to any financial institution or in connection with a
foreclosure, sale in lieu of foreclosure, deed in lieu of foreclosure, or
deed of the Assets or a substantial portion thereof by or to any such
financial institution, Seller shall be entitled to look to Buyer, Sterling
or Parent, as the case may be, for all purposes hereunder until such time,
and this Agreement and the other Related Agreements can be amended,
modified or waived by agreement among the Parties (without the concurrence
of the assignee) unless and until, Seller has received a written notice of
default from the assignee of such interests, rights and obligations.
Notwithstanding anything in this Agreement to the contrary, (i) Buyer,
Sterling or Parent may assign their respective rights and obligations under
this Agreement to (a) Parent or any of its Subsidiaries except Direct
Radiography Corp., or (b) to any person who acquires substantially all the
assets of Parent, Sterling or Buyer, and (ii) Seller may assign its rights
or obligations under this Agreement to any Person who acquires
substantially all the assets of Seller related to the Products covered in
the Film Supply Agreement.

            Notwithstanding any provision in this Section 17.04 to the
contrary, Seller shall remain liable for and with respect to all
obligations of Seller hereunder after any assignment by Seller or any
permitted assign of all or any portion of Seller's interest in this
Agreement or such other documents and instruments or its rights and
obligations hereunder or thereunder, and Buyer, Sterling and Parent shall
remain liable for and with respect to all obligations of Buyer, Sterling
and Parent hereunder after any assignment by Buyer, Sterling or Parent or
any permitted assign of all or any portion of its interest in this
Agreement or such other documents and instruments or its rights and
obligations hereunder or thereunder.

            Except as set forth in this Section 17.04, and except to the
extent that the Buyer Indemnified Parties and the Seller Indemnified
Parties shall be entitled to the benefits of the indemnities set forth
herein, no Person not a party to this Agreement shall have any rights under
this Agreement as a third-party beneficiary or otherwise.


     17.5   Non-Waiver of Remedy.  The failure of any Party to insist, in
any one or more instances, upon the strict performance of any of the terms,
conditions or covenants of this Agreement shall not be construed as a
waiver or relinquishment for the future of such term, condition or
covenant. A receipt by Seller, Buyer, Sterling or Parent of any money with
knowledge of the breach of any term, condition or covenant of this
Agreement, shall not be deemed a waiver of such breach, and no waiver,
change, modification or discharge by any Party hereto of any provision in
this Agreement shall be deemed to have been made or shall be effective
unless expressed in writing and signed by all Parties.  In addition to the
other remedies provided in this Agreement, the Parties shall be entitled to
the restraint by injunction of the violation, or attempted or threatened
violation of any of the terms, conditions or covenants of this Agreement,
or to a decree compelling performance of any of such term, condition or
covenant.

connection therewith, Sections 3.01, 3.04, 3.07 and 3.08 are hereby deleted
in  their  entirety  and  are hereby replaced in their  entirety  with  the
following:

         3.1  Assumption of Liabilities.  Except as provided in Section
    3.02,  Buyer  shall assume and agree to pay, discharge and  perform
    when  due  all  obligations (whether known  or  unknown,  fixed  or

    receipt of an invoice from Buyer, Seller or its Subsidiaries  shall

         3.04  Initial Inventory Value.  The Parties have  agreed  that
    the   initial  Inventory  Value  as  of  September  30,  1996,   is
    $29,209,875 (the "Initial Inventory Value").  The Initial Inventory
    Value  multiplied by 95% is $27,749,382, and such amount  shall  be
    referred to herein as the "Estimated Initial Inventory Value."

        3.07  Sales,  Use,  Transfer  and Similar  Taxes  and  Charges.
    Seller  shall  bear and pay all sales, use or stamp taxes  and  any
    transfer,  transfer  gain, documentation,  gross  receipts,  custom
    duties,  value  added,  withholding  tax,  recording,  filing   and
    registration  fees  and other taxes and charges,  as  well  as  all
    interest and penalties thereon payable upon or with respect to  the
    sale or transfer of the U. S. Assets by Seller to Buyer pursuant to
    this    Agreement    (collectively   the    "Transfer    Charges").
    Notwithstanding the foregoing, Buyer shall be required to  pay  all
    Transfer  Charges  for  which a refund,  recoupment  or  credit  is
    available to Buyer, and Buyer shall be entitled to obtain and  keep
    such  refund, recoupment or credit; provided, however, that  Seller
    shall  reimburse Buyer for any Transfer Charges paid by  Buyer  for
    which a refund, recoupment or credit is available but which is  not
    recovered  or  recouped by Buyer within twelve (12) months  of  the
    Closing Date.  If Buyer thereafter receives a refund, recoupment or
    credit  of  all  or  any portion of any Transfer Charge  for  which
    Seller  has  reimbursed Buyer, Buyer shall reimburse Seller  in  an
    amount equal to such refund, recoupment or credit.  Subject to  the
    foregoing  sentence, to the extent any applicable law or regulation
    imposes upon a Party the obligation to pay Transfer Charges  to  be
    borne  by  a  Party  pursuant to the preceding sentences  and  such
    Transfer   Charges  are  paid  by  such  other  Party,  the   Party
    responsible for such Transfer Charges pursuant to the two preceding
    sentences shall promptly reimburse such paying Party therefor  upon
    receipt  of  such  paying Party's invoice for the  amount  of  such
    payments.

        3.08  Purchase Price Adjustment.  In the event there  shall  be
    an inaccuracy in any of the representations or warranties of Seller
    or  a breach by Seller of one or more covenants to be performed  by
    Seller   prior  to  Closing  or  an   inaccuracy  in  any  of   the
    representations  or warranties of any Subsidiary  of  Seller  or  a
    breach  by  a Subsidiary of Seller of one or more covenants  to  be
    performed by such Subsidiary herein or in any documents executed by
    such  Subsidiary  in connection with the transactions  contemplated
    hereby,  which inaccuracy or breach is Material and such inaccuracy
    or  breach  does  not  constitute a failure of  the  conditions  to
    Buyer's  or its Subsidiaries' obligations to close as set forth  in
    Section  12.02(a), or there shall be a Material loss or  damage  to
    any  of the Assets as a result of fire or other casualty and Seller
    does  not elect to restore such Assets as provided in Section 8.09,
    the  Parties  shall use all reasonable efforts to  agree  prior  to
    Closing to a downward adjustment to the Purchase Price in an amount
    equal  to the decline in value of any of the Assets resulting  from
    such  inaccuracy,  breach, loss or damage.   In  this  regard,  the
    decline  in value shall be on a dollar-for-dollar basis for balance
    sheet items and, with respect to other items affecting value, shall
    be as mutually agreed by the Parties.  If the Parties are unable to
    agree  on  the  amount  of the Purchase Price adjustment  prior  to
    Closing,  and  all  of  the conditions to the  obligations  of  the
    Parties  to close have been satisfied or waived, the Parties  shall
    proceed  to  close  the  transaction contemplated  hereby  and  the
    disagreement regarding the amount of the Purchase Price  adjustment
    shall  be  resolved  in  accordance  with  the  dispute  resolution
    procedure  described  in Section 3.05(b), with  the  30-day  period
    referred to in the first sentence thereof beginning on the  Closing
    Date.    Once  such  disagreement  is  resolved,  Seller,  or   its
    Subsidiary,  as the case may be, shall then pay to  Buyer,  or  its
    Subsidiary,  as the case may be, the amount of such adjustment,  if
    any,  with interest at the rate provided in Section 3.05(d)(i) from
    the  Closing  Date  through  the date of payment.   Notwithstanding
    anything  herein  to the contrary, no downward  adjustment  in  the
    Purchase Price shall be made under this Section 3.08 to the  extent
    that  the  amount  thereof  is  subject  to  adjustment  under  the
    Inventory evaluation procedures elsewhere in this Article 3.

Agreement.  In connection therewith, Paragraph (c) of Section 3.03 is hereby
deleted  in  its  entirety and is hereby replaced in its entirety  with  the

    contemplated by this Agreement constitutes a taxable  sale  of  the
    Assets by the Seller and a purchase of the Assets by the Buyer, and
    Buyer  and  Seller shall report such transaction on  all  of  their
    income  tax  returns  in a manner consistent with  such  intention.

10.  Employee Benefit Matters.

    The parties to this Amendment desire to amend Sections 9.01, 9.02, 9.04,
9.06,  9.08  and  9.09  of  the Agreement to provide  for  the  transfer  of
employees  of  Subsidiaries of Seller to Buyer or Subsidiaries of  Sterling.
In  connection therewith, Sections 9.01, 9.02, 9.04, 9.06, 9.08 and 9.09 are
hereby  deleted in their entirety and are hereby replaced in their  entirety
with the following:

              9.01  Offer  of Employment.  Seller has provided  to
        Buyer  as of the date hereof a list of employees of Seller
        and   its   Subsidiaries  associated  with  the  Equipment
        Product  Lines  or  any of the Assets  setting  forth  the
        status of such employees and their compensation, who  will
        be  full-time,  active  employees  on  the  Closing  Date,
        including  those on temporary leave for jury duty,  family
        and  short-term medical leave, vacation or annual two-week
        military duty.  Buyer shall provide to Seller at least  10
        days  prior  to the Closing Date a list of such  employees
        to  whom  Buyer  or  its  Affiliates  or  Subsidiaries  of
        Sterling  will  offer  employment (the  "Employee  List").
        Seller  shall use all reasonable efforts and  shall  cause
        its  Subsidiaries  to  use all reasonable  efforts  (which
        does  not  include the increase in any benefits under  any
        employee  benefit program, plan or arrangement)  to  cause
        such  employees  to accept Buyer's or its  Affiliates'  or
        Subsidiaries   of   Sterling's   offers   of   employment.
        Reasonable  efforts for the purpose of this Article  shall
        mean communicating the benefits to such employees and  the
        benefits  set  forth  in this Article to  encourage  their
        employment  with Buyer, its Affiliates or Subsidiaries  of
        Sterling.   Reasonable efforts shall neither preclude  the
        Seller  or its Subsidiaries from retaining those employees
        who  do  not accept employment offers from the Buyer;  nor
        require  the  Seller or its Subsidiaries  to  provide  any
        payment  or  benefit  which  is  not  set  forth  in  this
        Agreement.    Prior  to  any  employee's   acceptance   or
        rejection  of  an  offer  of employment  from  the  Buyer,
        Seller   or   its  Subsidiaries  shall  not  provide   any
        incentive for any employee to remain in the employment  of
        the  Seller  or  its  Subsidiaries.  Those  employees  who
        accept  such offers of employment and become employees  of
        the  Buyer  or its Affiliates prior to February  14,  1997
        shall  be  referred to herein as "Transferred  Employees".
        Employees  listed  on the Employee  List  who  as  of  the
        Closing Date are on short term medical leave shall not  be
        deemed  Transferred Employees if they do  not  report  for
        work  within  six (6) months of the commencement  of  such
        leave  and  shall remain the responsibility of  Seller  or
        its Subsidiaries.

        otherwise   provided  in  this  Article   9,   Transferred
        Employees  shall  not be credited for their  service  with
        Seller  or its Subsidiaries for purposes of participation,
        eligibility  and  vesting  under  the  benefit  plans  and
        programs provided by Buyer or its Affiliates.
        
              9.04  Pension  Benefits.  On the date a  Transferred
        Employee  becomes  an  employee of Buyer  or  any  of  its
        Affiliates  as  set  forth  in  Section  9.01,   (i)   the
        Transferred  Employee that participates in  any  "employee
        pension  benefit  plan" (as defined  in  Section  3(2)  of
        ERISA)  that  is maintained by Seller or its  Subsidiaries
        (collectively, "Seller Pension Plans") shall cease  to  do
        so  and  (ii)  such  Transferred Employee  shall  commence
        participation  in any "employee pension benefit  plan"  of
        Buyer  or its Affiliates for individuals employed by Buyer
        of  its  Affiliates (collectively, "Buyer Pension  Plans")
        upon the satisfaction of any eligibility requirements  set

        Employees  or  employees of Seller arising  out  of  their
        employment with Seller or its Subsidiaries including,  but
        not  limited  to,  claims  arising  out  of  any  employee
        benefit  plan maintained by Seller or its Subsidiaries  or
        for   retiree  medical  benefits  promised,  provided   or
        subsidized  by  Seller  after the Closing  Date  (as  such
        employee  benefit  plans  of Seller  or  its  Subsidiaries
        exist  when  claims  are  to be  paid  by  Seller  or  its
        Subsidiaries  and  recognizing that such employee  benefit
        plans  of  Seller  or  its Subsidiaries  may  be  amended,
        modified or terminated).

                   (b)   Except for liabilities assumed by  Seller
        or  its  Subsidiaries under this Article 9, Buyer  or  its
        Affiliates  shall discharge all liabilities to and  claims
        of  Transferred  Employees or employees of  Buyer  or  its
        Affiliates arising out of their employment with  Buyer  or
        its  Affiliates including, but not limited to, any  claims
        arising  out  of any employee benefit plan  maintained  by
        Buyer or its Affiliates.

              9.08  Vacation.   Seller or its  Subsidiaries  shall
        discharge  its liability to any Transferred  Employee  for
        vacation   accrued   through  the   date   a   Transferred
        Employee's  employment with the Seller or its Subsidiaries
        terminates.   With  respect  to  a  Transferred  Employee,
        Buyer   or   its  Affiliates  shall  credit  all   service
        recognized  under  Seller's or its Subsidiaries'  vacation
        policy  through  a  Transferred  Employee's  last  day  of
        employment  with  Seller  or  its  Subsidiaries   in   the
        calculation  of  the  amount  of  vacation  a  Transferred
        Employee  has  accrued under Buyer's  or  its  Affiliate's
        vacation policy.

              9.09   Severance.    Seller  shall   discharge   its
        liability   to  any  Transferred  Employee  for  severance
        benefits   accrued   through  the   date   a   Transferred
        Employee's  employment with the Seller or its Subsidiaries
        terminates.   With  respect  to  a  Transferred  Employee,
        Buyer   or   its  Affiliates  shall  credit  all   service
        recognized  under Seller's or its Subsidiaries'  severance
        policy  through  a  Transferred  Employee's  last  day  of
        employment  with  Seller  or  its  Subsidiaries   in   the
        calculation   of  the  amount  of  severance   benefit   a
        Transferred  Employee  has accrued under  Buyer's  or  its
        Affiliate's severance policy or program.

11.   The parties to this Amendment desire to amend Paragraph (a) of Section
9.03  of  the  Agreement  to  provide  for  the  transfer  of  employees  of
Subsidiaries of Seller to Buyer or Subsidiaries of Sterling.  In  connection
therewith,  Paragraph (a) of Section 9.03 is hereby deleted in its  entirety
and is hereby replaced in its entirety with the following:

                   (a)  On the date a Transferred Employee becomes

        Subsidiaries  (collectively, the "Seller  Welfare  Plans")
        shall  cease  to  do  so  and  (ii)  except  as  otherwise
        provided   in  Sections  9.03(c),  9.08  and  9.09,   such
        Transferred   Employee  and  dependents   shall   commence
        participation in any "employee welfare benefit  plan"  (as
        defined  by Section 3(1) of ERISA) maintained by Buyer  or
        its  Affiliates for individuals employed by Buyer  or  its

    The  parties  to  this Amendment desire to amend Section  13.07  of  the
Agreement  to  provide for the protection of Confidential  Material  by  the

therewith,  Section 13.07 is hereby deleted in its entirety  and  is  hereby
replaced in its entirety with the following:

    13.07     Confidentiality.

        (a)    In   addition  to  any  obligations  of  confidentiality
    pursuant   to  other  agreements  between  the  Parties  or   their
    Affiliates,  without the prior written consent of the other  Party,
    each  Party  shall  and  shall cause its Subsidiaries  to  hold  in
    confidence and not disclose to any third party (i) any confidential
    information   received  by  it  from  the  other   Party   or   its
    Subsidiaries,   and  (ii)  the  specific  terms,   conditions   and
    information  contained  in  this  Agreement,  any  of  the  Related
    Documents  and  any other documents contemplated in this  Agreement
    (collectively, "Confidential Material").

        (b)   Each  Party  agrees that it shall  and  shall  cause  its
    Subsidiaries to use the Confidential Material only for the purposes
    of  carrying  out the transactions contemplated by this  Agreement,
    the  Related Documents and any other documents contemplated in this
    Agreement.
        (c)   For the purposes of this Agreement, Confidential Material
    shall not include information:

              (i)   that is or becomes part of the public domain or  is
    otherwise  generally  available to the public  other  than  through
    breach  of  this Agreement, the Related Documents or any  documents
    contemplated  in  this  Agreement  or  through  the  fault  of  the
    receiving Party or its Subsidiaries;

              (ii)   that is or becomes available to another  Party  or
    its Subsidiaries, from an unaffiliated source, which source has  no
    obligation of secrecy to the Parties or their Subsidiaries;



                                    -23-
<PAGE>



              (iii)   that is disclosed (a) in any SEC filing;  or  (b)
    that  is required to be disclosed by law or governmental regulation
    or  order or upon the advice of counsel, provided that the Party or
    its  Subsidiary  disclosing such information shall give  the  other
    Parties  to  this  Agreement  reasonable  advance  notice  of  such
    disclosure; or

              (iv)  that the Parties mutually agree in writing to disclose.

    Party or any Party's Subsidiaries of any of the provisions of  this
    Section  8.01, money damages would be inadequate and that the  non-
    breaching Party would have no adequate remedy at law.  Accordingly,
    notwithstanding  anything  to  the  contrary  contained   in   this
    Agreement, the Parties agree that the Parties shall have the right,
    in  addition  to  any other rights and the obligations  under  this
    Section 8.01, to seek an adequate remedy for such breach, not  only
    by  an  action  for damages but also by an action  or  actions  for
    specific  performance, injunction and/or other equitable relief  in
    order  to  enforce or prevent any violations (whether anticipatory,
    continuing or future) of the provisions of this Section 8.01.

Agreement  to provide for the inclusion of the Subsidiaries of the  Parties.

    other  agreements  contemplated in this Agreement,  no  conditions,
    usage of trade, course of dealing or performance, understanding  or
    agreement  purporting to modify, vary, explain  or  supplement  the
    terms or conditions of this Agreement shall be binding unless  made
