Item 5.  Acquisition or Disposition of Assets

On September 9, 1998, Interleaf, Inc. (the "Company") entered into Stock 
Purchase Agreements effective as of August 31, 1998 (collectively the 
"Purchase Agreements") with each of Dona D. Ray, Davis K. Marksbury, Jr., and 
Donald J. Kloiber (the "Sellers"), the three owners of all of the capital 
stock of PDR Automated Systems & Publications, Inc., a Kentucky corporation 
("PDR").  PDR is a company engaged in the business of providing technical 
documentation services.

Pursuant to the terms of the Purchase Agreements, the Company acquired all of 
the capital stock of PDR as of August 31, 1998 for (i) approximately $2.7 
million in cash plus six month warrants to purchase 250,000 shares of Company 
common stock at an exercise price of $2.85 issued at closing, and (ii) an 
installment payment of $1.5 million on March 31, 1999 (subject to adjustment) 
and a second installment payment to bring the total to $3.0 million (also 
subject to adjustment) on September 30, 1999 (collectively, the "Installment 
Payments").  In addition, the Company agreed to pay the Sellers an aggregate 
of $75,000 in cash, payable 50% at the closing and 50% in February 1999, and 
to pay to them any amounts PDR receives with respect to certain accounts 
receivable.  

The first Installment Payment is subject to decrease (but not below $500,000 
in the aggregate) or increase (but not beyond $2.5 million in the aggregate) 
by differing percentages of the amount, if any, by which the revenues of PDR 
during the six-month period followed the closing derived from certain 
customer accounts exceed or are less than $1.5 million.  The second 
Installment Payment is subject to similar adjustment (with a zero floor and 
no ceiling) based upon the amount by which such revenues for the full 
12-month period following closing exceed or are less than $3 million.

Each Installment Payment is payable in the form of Company common stock 
having a market value (defined by reference to a trailing ten day average 
trading price) on the date of delivery equal to the dollar amount due on the 
Installment Payment, except that the Company has the option of paying in cash 
rather than stock if the market value of its common stock is less than $2.85 
per share or if, despite its reasonable efforts, the shares to be delivered 
have not been registered under the Securities Act of 1933, as amended, for 
resale by the Sellers.  The Company further agreed that to the extent that it 
makes an Installment Payment in the form of its common stock and the Sellers 
resell that stock in the public markets in the manner provided in the Stock 
Purchase Agreements and those sales result in the Sellers receiving less than 
90% of the dollar amount of the Installment Payment, the Company will make an 
additional cash payment to the Sellers to bring the amount received up to 90% 
and repurchase any remaining unsold shares.  

In connection with the execution of the Stock Purchase Agreements, the 
Company also entered into a one year employment agreement with Dona Ray and 
one year consulting agreements with the other two stockholders of PDR, each 
of which includes a noncompetition provision.  The aggregate amount payable 
under these three agreements is $225,000. 

                                          2

The assets of PDR acquired as a result of the stock purchases are

software programs, office leases and office furnishings and equipment.

The acquisition was financed out of the Company's working capital.

Article 10.

1.2    Adjustment of Installment Payments.  The Installment Payments payable 
under Sections 1.1(d) and (e) above shall be subject to adjustment as set 
forth below:

       (a)    The amount of the First Installment Payment shall be adjusted as 
follows:

         (i)  It shall be increased by 38% of the amount, if any, by which 
              Key Location Revenue recognized by Buyer during the First 
              Installment Period exceeds $1,500,000; provided, that the 
              First Installment Payment shall not be increased by more than 
              Seven Hundred Sixty Thousand Dollars ($760,000.00); and

       (ii)   It shall be reduced by 24% of the amount, if any, by which 
              Key Location Revenue recognized by Buyer during the First 
              Installment Period is less than $1,500,000; provided, that the 
              amount of the First Installment Payment shall not be reduced 
              below One Hundred Sixty Thousand Dollars ($160,000.00);

       (b)    The amount of the Second Installment Payment shall be the 
amount calculated as follows (but shall not be less than zero):  (i) 
calculate the amount by which Key Location Revenue is less than or more than 
$3,000,000 for the Combined Installment Period; (ii) multiply that amount by 
38% if it is a positive number or by 24% if it is a negative number; (iii) 
add that amount to $3,000,000 if it is positive or subtract it from 
$3,000,000 if it is negative; and (iv) subtract the amount of the First 
Installment Payment.

       (c)    The adjustment of any Installment Payment based upon the level 
of Key Location Revenues is premised upon compliance by both Buyer and Sellers 
with written agreement to be entered into (which shall constitute an Ancillary 
Agreement) in which they will agree on certain operational management issues 
during the Combined Installment Period.

either Installment Payment in the form of cash rather than Interleaf Shares 
if:

     (i)  on the due date for payment of such Installment Payment, 
          notwithstanding reasonable efforts by Buyer, a registration 
          statement under the Securities Act covering resale of such 
          Interleaf Shares shall not have been declared effective by the 
          SEC; or

     (ii) on the due date for payment of such Installment Payment or on any 
          one of the three trading days immediately preceding such due date, 
          the Market Value of Buyer's Common Stock is equal to or less than 
          $2.85 per share.

1.4  Procedures With Respect to Calculation of Adjustments to Installment 
Payments.

     (a)  Buyer will calculate the Key Location Revenue for each fiscal 
quarter of the Combined Installment Period (the quarters ended on the last 
day of November 1998 and February, May and August 1999) and Buyer's Chief 
Financial Officer shall deliver a report to Seller certifying as to the Key 
Location Revenues for that period not later than 20 calendar days after the 
end of the period.  

     (b)  Seller shall have the right by notice to Buyer within sixty (60) 
days after the end of either Installment Period to have an audit of the Key 
Location Revenue for either the First Installment Period or the Combined 
Installment Period performed by an independent public accounting firm of its 
choice, provided that it shall consider in good faith a proposal by 
PricewaterhouseCoopers LLC for such engagement.  The expenses of that audit 
will be borne by Seller and not by the Buyer, unless the amount owed to 
Seller as determined by such independent auditing firm is determined to be 
10% or more larger than the amount certified by Buyer's Chief Financial 
Officer; in which case Buyer shall reimburse Seller for the cost of the 
audit.

 1.5 Price and Liquidity Protection

     (a)  If the Seller receives Interleaf Shares as payment of either 
Installment Payment, the Seller agrees to attempt in good faith to sell such 
Interleaf Shares during the applicable Selling Period as follows:

     (i)  Seller shall coordinate his/her sales during the applicable Selling 
          Period with those of all other Sellers through a single registered 
          broker/dealer;

    (ii)  the Sellers collectively shall offer during each week of the 
          applicable Selling Period to sell between 5% and 10% of the 
          aggregate number of Interleaf Shares delivered to all Sellers at 
          the beginning of such Selling Period; provided, that the Sellers 
          collectively shall not, without Buyer's consent, offer to sell more 
          than either (A) 125% of the Average Daily Volume (measured on the 
          first trading day of that week) during any given week, or (B) the 
          lesser of (x) 5% of all Interleaf Shares delivered on the first day 
          of that Selling Period, or (y) 50% of the Average Daily Volume on 
          any given trading day;

   (iii)  the price at which any Interleaf Share are offered for sale shall 
          be not less than the volume-weighted average of the averages of the 
          high and low reported trading prices of Buyer Common Stock on the 
          Nasdaq National Market for the ten trading days preceding the day 
          that such Interleaf Shares are offered for sale; and

     (iv) none of the Sellers shall directly, indirectly or through any of 
          their respective family members, affiliates, employees or agents, 
          or anybody acting on their behalf, engage in any short sales, 
          swaps, purchasing of puts, or other hedging activities, that 
          involve the direct or indirect use of Buyer Common Stock or 
          securities derivative from Buyer Common Stock, for any reason.

     (b)  The inability of the Seller to sell any portion of the Interleaf 
Shares because of the price and volume limitations set forth in paragraph (a) 
above shall not constitute failure to comply with the obligation to endeavor 
to sell Seller's Interleaf Shares for purposes of this Section 1.5.

     (c)  If the Sellers reasonably comply with their obligations to sell the 
Interleaf Shares in the manner described above, and provided that the other 
terms and conditions of this Agreement are satisfied, Buyer agrees that on 
the first business day following the completion of the applicable Selling 
Period, Buyer will:

     (i)  pay to Seller an amount equal to ninety percent (90%) of (A) the 
          applicable Installment Payment minus the aggregate gross proceeds 
          received by the Seller from the sale of the his/her Interleaf 
          Shares during such Selling Period, multiplied by (B) the percentage 
          of Interleaf Shares in that Installment that were actually sold by 
          Seller; and 


                                        Page 4

<PAGE>

     (ii) offer to repurchase from Seller any Interleaf Shares which were not 
          sold during such Selling Period at a price per share equal to 
          the-then current Market Value for Buyer Common Stock; provided, 
          however, that such repurchase price shall not be less than 90% nor 
          more than 110% of the Market Value of the Buyer Common Stock on the 
          date of delivery of the Interleaf Shares as payment for that 
          Installment.

     (d)  Seller may, by written notice to Buyer before the close of business 
on the first trading day of any week, elect not to sell some or all of the 
Interleaf Shares otherwise to be offered during that week (such number to be 
not less than 5% or more than 10% of the aggregate number of Interleaf Shares 
delivered at the beginning of the applicable Selling Period).  Any shares so 
elected shall not be considered as sold for purposes of paragraph (c)(i) 
above and shall no longer be eligible for repurchase under paragraph (c)(ii) 
above.

     (e)  As security for Buyer's obligations under this Section 1.5, Buyer 
shall deliver to Seller at the time of making the First Installment Payment,  
and thereafter shall maintain in place until the payment of amounts due under 
Section 1.5(c), collateral to secure its obligations hereunder with a value 
equal to 25% of the amount of the Installment Payments remaining unpaid from 
time to time (without taking into account adjustment under Section 1.2), 
reduced by the Market Value of any Interleaf Shares removed from the selling 
programs under paragraph (d) above.  This collateral security shall be in the 
form of an irrevocable stand-by letter of credit or other form reasonably 
satisfactory to the Seller.

1.6  Time and Place of Closing.  The Closing shall be held at the offices of 
Brown, Rudnick, Freed & Gesmer at 10:00 a.m., on September 8, 1998, or at

(i) the net book value of the Company on the Closing Date would have been not 
less than $1,376,000, and (ii) cash and cash equivalents on the Closing would 
have been not less than $440,000.  The parties may agree on a holdback from 
the payment under Section 1.1(a) until the Closing Date Balance Sheet is 
delivered.

Closing, at the request of Buyer and without further consideration, shall

     (a)  The Company has duly and timely filed all Tax Returns with respect 
to all Taxes.  All of the Tax Returns are complete and correct in all 
respects.  The Federal and state Tax Returns filed by the Company for the 
most recent five (5) fiscal years are listed on Schedule 2.10 and have been 
delivered to the Buyer.  All Taxes shown to be due on such Tax Returns have 
been paid or are being contested in good faith by the Company and such 
contest is being diligently pursued, all of which contested Taxes are listed 
on Schedule 2.10.  With respect to all other Taxes for which no return is 
required or which have not yet accrued or otherwise become due, adequate 
provision has been made in the pertinent financial statements referred to in

only for calendar year 1994.  They have never been examined by the States of 
Kentucky, California, Massachusetts or North Carolina.  The Company is not 
aware of any intention on the part of any Governmental Authority to examine 
any of the Tax Returns.  No deficiencies have been asserted or assessments 
made against the Company, nor is the Internal Revenue Service nor any other 
Governmental Authority now asserting or, to the knowledge of the Company or 
any Seller, threatening to assert against the Company any deficiency or claim 
for additional taxes or interest thereon or penalties in connection 
therewith.  The Company has not extended the time for the filing of any Tax 
Return or the assessment of deficiencies or waived any statute of limitations 
for any year, which extension or waiver is still in effect.

     (c)  The Company has not filed a consent under Section 341(f) of the 
Code.

the Code, and the Company and its predecessors have at all times since its 
incorporation had, and at the time of Closing will have, valid Federal 
elections to be taxed as an S-Corporation and have never been subject to tax 
under Subchapter C of the Code.  The Company has had since its incorporation, 
and will have on the Closing Date, a valid S election in effect under the 
laws of the State of Kentucky.

     (a) Promptly after receipt of notice of any Third Party Action, any

the Indemnifying Person agrees (i) to promptly indemnify the Indemnified 
Person for its expenses to date, and (ii) to hold the Indemnified Person 
harmless from and against any and all Losses caused by or arising out of any 
settlement of the Third Party Action approved by the Indemnifying Person or 
any judgment in connection with that Third Party Action.  The Indemnifying 
Persons shall not in the defense of the Third Party Action enter into any 
settlement which does not include as a term thereof the giving by the third 
party claimant of an unconditional release of the Indemnified Person, or 
consent to entry of any judgment except with the consent of the Indemnified 
Person.

   (d) Upon assumption of control of the defense of a Third Party Action 
under paragraph (c) above, the Indemnifying Person will not be liable to the 
Indemnified Person  

                                       Page 33

hereunder for any legal or other expenses subsequently incurred in connection

rise to the applicable liability, payment, obligation or expense may have 
been previously disclosed to any such person unless expressly disclosed on 
each particular Schedule requiring such disclosure.

   (b) If any Loss is recoverable under more than one provision hereof, the 
Indemnified Person shall be entitled to assert a claim for such Loss until 
the expiration of the longest period of time within which to assert a claim 
for Loss under any of the provisions which are applicable.

   (c) Buyer may, at its option, recover any amount owing by the Sellers for 
indemnification hereunder by setoff against any amounts that may otherwise be 
due from the Buyer or the Company to the Seller whether hereunder or 
otherwise, to the extent provided in Section 11.2; provided that Buyer shall 
not be required to recover such claims in such manner and may proceed against 
the Indemnified Party at any time or times for recovery of indemnification 
claims.

8.5    Payment of Indemnification.

Claims for indemnification under this Article 8 shall be paid or otherwise

covenants and obligations herein or in any schedule, certificate or financial 
statement delivered by any party to another party incident to the 
transactions contemplated hereby are material, shall be deemed to have been 
relied upon by the other party and shall survive the Closing for the 
applicable periods set forth in Article 8 and shall be further actionable 
subject to the limitations set forth therein, regardless of any investigation 
and shall not merge in the performance of any obligation by either party 
hereto.

11.2   Right to Offset.  Buyer has the right to offset and credit any and/or 
all payments to be made by it under this Agreement to or for the benefit of 
the Sellers (other than the First Installment Payment, which shall not be

against Seller or the Company for indemnification pursuant to Section 8.1 
hereof.  If the Buyer does exercise its right of set-off hereunder, it shall 
give Seller ten calendar days advance written notice of that fact in 
accordance with the provisions hereof.  If Buyer does exercise its right of 
set-off, it shall do so for all Sellers pro rata to their ownership interests

(a "Reorganization Transaction") Buyer will use its best efforts to obtain an 
agreement of the other parties to the Reorganization Transaction either (i) 
to repurchase any remaining Interleaf Shares for an amount in cash equal to 
the net minimum obligation of Buyer under the price guaranty provided by 
Section 1.5(c) as of the date of such Reorganization Transaction, or (ii) to 
agree that the price and liquidity provisions set forth in Section 1.5 hereof 
are applicable to the securities of the acquiring or surviving entity  
received by the Seller in  the Reorganization Transaction.  Buyer shall not 
have the obligation under (ii) of the preceding sentence to obtain comparable 
price and liquidity protection for the benefit of the Seller if in Buyer's 
opinion such agreement would prevent the Buyer's use of a pooling of 
interests method of accounting; provided, that if the Seller does not receive 
comparable price and liquidity protections in connection with the 
Reorganization Transaction, then the Buyer shall offer on one occasion to 
repurchase Seller's Interleaf Shares at a price per share equal to not less 
than 90% nor more than 110% of the Market Value of the Interleaf Shares on 
the date of delivery of the Interleaf Shares being repurchased.

compliance by Buyer with applicable stock market rules or securities laws 
(and subject to applicable limitations contained in contracts to which the 
Company is a party), neither Buyer nor the Company shall issue nor approve 
any news release or other public announcement concerning this Agreement (or

release concerning the execution of this Agreement or consummation of the

and not disclose or divulge any confidential, proprietary or secret 
information which they may obtain from another party hereto in connection 
with the transactions contemplated herein, or pursuant to inspection rights 
granted hereunder, or reveal the financial or other terms and conditions of 
this Agreement unless such information is or hereafter becomes public 
information through means other than a default hereof by such party or is 
required to be disclosed by applicable law, including applicable securities 
laws or stock exchange rules or regulations; provided, however, that Buyer 
shall use its reasonable best efforts to obtain any consents of third parties 
or confidential treatment, as applicable, in connection with the disclosure 
of information relating to contracts to which the Company is a party as may 
be required by the terms of such contracts.  The obligations of this Section 
10.7 shall survive any termination of this Agreement.

11.8   Time Period.  The parties acknowledge that time is of the essence with 
respect to the fulfillment of the respective obligations of the parties 
hereto and the Closing of the Transaction as contemplated by this Agreement.

11.9   Entire Agreement.  This Agreement (including all exhibits or schedules

<PAGE>

the subject matter hereof and inducements to the making of this Agreement 
relied upon by any party hereto, have been expressed herein or in the 
documents incorporated herein by reference.

11.10  Severability.  The invalidity or unenforceability of any provision of 
this Agreement shall not affect the validity or enforceability of any other 
provision hereof.

11.11  Assignability.  This Agreement may not be assigned otherwise by 
operation of law or otherwise (a) by Buyer without the prior written consent 
of Sellers or (b) by Sellers without the prior written consent of Buyer.  
However, any or all rights of Buyer to receive performance (but not the 
obligations of Buyer to Sellers hereunder) and rights to assert claims 
against Sellers in respect of breaches of representations, warranties or 
covenants of Sellers hereunder, may be assigned by Buyer to any direct or 
indirect subsidiary or other affiliate of Buyer, but any such assignee of 
Buyer's rights hereunder shall take such rights subject to any defenses, 
counterclaims and rights of setoff to which Sellers might be entitled under 
this Agreement.  This Agreement shall inure to the benefit of and be binding 
upon the parties hereto and their respective successors and permitted assigns.

11.12  Amendment.  This Agreement may be amended only by a written agreement 
executed all parties hereto.

11.13  Governing Law. 

   (a) This Agreement shall be governed by and construed in accordance with 
the laws of The Commonwealth of Massachusetts (other than the choice of law 
principles thereof), except that any representations and warranties with 
respect to real and tangible property shall be governed by and construed in 
accordance with the laws of the jurisdiction where such property is situated.

   (b) Any claim, action, suit or other proceeding initiated by any party to 
this Agreement, under or in connection with this Agreement may be asserted, 
brought, prosecuted and maintained in any Federal or state court in The 
Commonwealth of Massachusetts, as the party bringing such action, suit or 
proceeding shall elect, having jurisdiction over the subject matter thereof, 
and the parties hereby waive any and all rights to object to the laying of 
venue in any such court and to any right to claim that any such court may be 
an inconvenient forum. Each of the Parties hereby submit themselves to the 
jurisdiction of each such court and agree that service of process on them in 
any such action, suit or proceeding may be effected by the means by which 
notices are to be given to it under this Agreement.

11.14  Remedies.  The parties hereto acknowledge that the remedy at law for 
any breach of the obligations undertaken by the parties hereto is and will be 
insufficient and inadequate and that the parties hereto shall be entitled to 
equitable relief, in addition to remedies at law.  In the event of any action 
to enforce the provisions of this Agreement, Sellers shall waive the defense 
that there is an adequate remedy at law.  Sellers acknowledge that the 
Company Shares are unique and cannot be obtained on the open market.  Without 
limiting any remedies Buyer may otherwise have hereunder or under applicable 
law, in the event Sellers refuse to perform their obligations under this 
Agreement, Buyer shall have, in addition to any other rights at law or 
equity, the right to specific performance.
