The unaudited Consolidated Financial Statements have been prepared in
accordance with generally accepted accounting principles and with

B.  ACQUISITION:

On July 1, 1998, the Company, through its Research and Diagnostics Systems,
Inc. subsidiary, acquired the research products business of Genzyme
Corporation.  Assets acquired were as follows:

     Inventories          $ 5,660,000
     Equipment                320,000
     Customer list         17,000,000
                          -----------
                          $22,980,000
                          ===========

The purchase price paid and payable for the acquisition is as follows:
$24.76 million cash, 987,206 shares of Techne common stock valued at $17
million and $18.84 million of royalties (present value of an estimated
$23.7 million payable over five years) on the Company's biotechnology
sales.  The excess of the consideration (including acquisition costs) over
the fair market value of the assets acquired has been recorded as goodwill
and is being amortized on a straight-line basis over six years.  The
customer list is being amortized on a declining basis over an estimated
economic life of five years.

Pro forma financial information for the quarter and six months ended
December 31, 1997, presented as if the acquisition had occurred on July 1,
1997, are as follows (in 000's except earnings per share data):

D.  SUBSEQUENT EVENT:

On January 22, 1999, the Company entered into agreements to acquire real
estate which its wholly-owned subsidiary, R&D Systems, currently occupies
in Minneapolis, Minnesota.  The purchase price of the properties is
approximately $28 million, which will be paid through the issuance of
100,000 shares of Common Stock and cash of approximately $25.8 million.  A
substantial portion of the cash requirement will be obtained through
mortgage financing.  The closing of the purchase transaction is expected to 
be in July, 1999.

In addition to agreements to purchase the currently occupied properties,
the Company has acquired options on property adjacent to its R&D Systems'
facility to provided future expansion space for the Company.




        ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                    CONDITION AND RESULTS OF OPERATIONS

   Results of Operations Quarter and Six Months Ended December 31, 1998
            vs. Quarter and Six Months Ended December 31, 1997

Techne Corporation (Techne) has two operating subsidiaries:  Research and
Diagnostic Systems, Inc. (R&D Systems) located in Minneapolis, Minnesota
and R&D Systems Europe Ltd. (R&D Europe) located in Abingdon, England.  R&D
Systems has two divisions:  Biotechnology and Hematology.  The Biotechnology 
Division manufactures purified cytokines (proteins), antibodies and assay 
kits which are sold primarily to biomedical researchers and clinical research 
laboratories.  The Hematology Division develops and manufactures whole blood 
hematology controls and calibrators which are sold to hospital and clinical 
laboratories to check the performance of their hematology instruments to 
assure the accuracy of hematology test results.  R&D Europe sells R&D 
Systems' biotechnology products in Europe, both directly and through a sales 
subsidiary in Germany.  The Company has a foreign sales corporation, Techne 
Export Inc.

In November 1997, January 1998 and July 1998, Techne purchased a total of
$3 million of preferred stock of ChemoCentryx, Inc. (CCX), representing
approximately 37% of issued and outstanding voting shares.  In addition,
Techne is obligated to purchase up to an additional $2 million of preferred
stock over the next year upon CCX's achievement of certain milestones.  After 
purchase of the additional preferred shares, Techne will own approximately 
49% of the issued and outstanding voting shares (assuming no investment by 
other parties).  Techne has consolidated CCX into its financial statements 
due to the limited amount of cash consideration provided by the holders of 
the common shares of CCX.  CCX is a new technology and drug development 
company working in the area of chemokines.  Chemokines are cytokines which 
regulate the trafficking patterns of leukocytes, the effector cells of the 
human immune system.  In conjunction with the equity investment and joint 
research efforts, Techne obtains exclusive worldwide research and diagnostic 
marketing rights to chemokine proteins, antibodies and receptors discovered 
or developed by CCX or R&D Systems.

Net Sales

Net sales for the quarter ended December 31, 1998 were $21,464,259, an
increase of $5,991,402 (39%) from the quarter ended December 31, 1997.
Sales for the six months ended December 31, 1998 increased $11,789,451
(38%) from $31,010,000 to $42,799,451.  R&D Systems sales increased
$4,368,189 (40%) and $8,732,439 (38%) for the quarter and six months ended
December 31, 1998, respectively.  R&D Europe sales increased $1,623,213
(37%) and $3,057,012 (37%) for the quarter and six months ended December
31, 1998, respectively.

The increase in sales for the quarter and six months was due, in part, to
the acquisition of Genzyme Corporation's research products business on July
1, 1998.  Sales of these products were $1,701,770 and $4,164,797 for the
quarter and six months ended December 31, 1998, respectively.  In addition,
the increase in consolidated sales for the quarter and six months was due
to increased sales of R&D Systems' cytokines, antibodies and immunoassay
kits to both R&D Systems customers and to former Genzyme customers as they
are converted from Genzyme products to R&D Systems products.

Gross Margins

Gross margins, as a percentage of sales, increased slightly from the prior
year.  Margins for the second quarter of fiscal 1999 were 71.0% compared to
68.4% for the same quarter in fiscal 1998.  Margins for the six months
ended December 31, 1998 were 70.0% compared to 69.6% for the same period in
fiscal 1998.

R&D Europe gross margins decreased from 48.6% to 46.4% for the quarter and
from 50.6% to 46.6% for the six months ended December 31, 1998 as a result
of the conversion from both manufacturing and sales activities to a sales
only function through the transfer of all manufacturing activities to R&D
Systems during fiscal 1998.  Hematology Division gross margins increased
from 42.2% to 47.2% for the quarter and from 45.5% to 46.6% for the six
months ended December 31, 1998 as a result of changes in product mix and
increased volumes.  Biotechnology Division gross margins increased from
70.9% to 72.11% for the quarter, but decreased slightly from 72.0% to 71.0%
for the six months ended December 31, 1998.  The decrease in Biotechnology
Division gross margins for the six months was a result of lower gross
profit levels on the inventory acquired from Genzyme during the first
quarter of fiscal 1999.  In the second quarter, the lower gross profit on
Genzyme products was offset by the increased sales of higher margin R&D
Systems products.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $617,988 (16%) from
the second quarter of fiscal 1998 to  the second quarter of fiscal 1999.
These expenses also increased $1,045,679 (13%) for the first six months of
fiscal 1999.  The majority of the increase for the quarter and six months
was due to additional sales personnel added in the U.S. and Europe as a
result of the Genzyme acquisition.

Research and Development Expenses

Research and development expenses increased $426,328 (17%) and $712,605
(14%) for the quarter and six months ended December 31, 1998.  The increase
related to products currently under development, many of which have been or
will be released in fiscal 1999.  Products currently under development
include both biotechnology and hematology products.

Amortization Expense

Amortization expense increased $2,384,999 and $4,737,190 for the quarter
and six months ended December 31, 1998 as a result of the customer list and 
goodwill associated with the Genzyme acquisition.

Net Earnings

Earnings before income taxes increased $1,163,863 from $4,497,984 in the
second quarter of fiscal 1998 to $5,661,847 in the second quarter of fiscal
1999.  Earnings before taxes for the six months increased $1,795,325 from
$9,221,366 to $11,016,691.  The increase in earnings before income taxes
was due mainly to an increase in Biotechnology Division earnings of $867,983 
and $1,722,086, an increase in R&D Europe earnings of $306,745 and $366,627, 
and an increase in Hematology Division earnings of $232,478 and $205,050 for 
the quarter and six months ended December 31, 1998.  These increases were 
reduced by a net loss by CCX in the second quarter and first six months of 
fiscal 1999.

Income taxes for the quarter and six months ended December 31, 1998 were
provided at a rate of approximately  37% and 35% of consolidated pretax
earnings compared to 30% and 31% for the prior year.  The increase in the
tax rate is due to the net loss by CCX in the second quarter and first six
months of fiscal 1999 for which no tax benefit has been provided.  U.S.
federal taxes have been reduced by the credit for research and development
expenditures and the benefit of the foreign sales corporation.  Foreign
income taxes have been provided at rates which approximate the tax rates in
the United Kingdom and Germany.
                                     
                                    
                      Liquidity and Capital Resources

At December 31, 1998, cash and cash equivalents and short-term investments
were $25,751,886 compared to $42,694,280 at June 30, 1998.  The decrease
from June 30, 1998 was due to the cash outlay for the Genzyme acquisition.
The Company believes it can meet its future cash, working capital and
capital addition requirements (excluding real estate to be acquired in July, 
1999) through currently available funds, cash generated from operations
and maturities of short-term investments.  The Company has an unsecured
line of credit of $750,000.  The interest rate on the line of credit is at
prime.  There were no borrowings on the line in the prior or current fiscal
years.

Cash Flows From Operating Activities

The Company generated cash of $11,027,874 from operating activities in the
first six months of fiscal 1999 compared to $8,926,641 for the first six
months of fiscal 1998.  The increase was mainly the result of increased net
earnings adjusted for noncash expenses partially offset by increased accounts 
receivable.

Cash Flows From Investing Activities

On July 1, 1998 the Company acquired the research products business of
Genzyme Corporation for $24.76 million cash, $17 million common stock and
royalties on the Company's biotechnology sales for five years.  Cash and
cash equivalents at June 30, 1998 and maturities of short-term investments
were used to finance the cash portion of the acquisition.

During the six months ended December 31, 1998 short-term investments
decreased by $3,221,224.  During the six months ended December 31, 1997,
the Company increased short-term investments by $6,340,884.  The Company's
investment policy is to place excess cash in short-term tax-exempt bonds.
The objective of this policy is to obtain the highest possible return with
the lowest risk, while keeping the funds accessible.

Capital additions were $1,525,295 for the first six months of fiscal 1999,
compared to $1,648,881 for the first six months of fiscal 1998.  Included
in the fiscal 1999 and 1998 additions were $683,000 and $721,000 for
leasehold improvements related to remodeling of facilities by R&D Systems.
The remaining additions in fiscal 1999 and 1998 were for laboratory and
computer equipment.  Total expenditures for capital additions planned for
the remainder of fiscal 1999 are expected to cost approximately $4.5
million and are expected to be financed through currently available funds
and cash generated from operating activities.

Cash Flows From Financing Activities

Cash of $752,894 and $367,796 was received during the six months ended
December 31, 1998 and 1997, respectively, for the exercise of options for
158,420 and 46,540 shares of common stock.  During the first six months of
fiscal 1998, options for 24,506 shares of common stock were exercised by
the surrender of 7,624 shares of the Company's common stock with a fair
market value of $126,194.

During the first six months of fiscal 1999 and 1998, the Company purchased
and retired 138,600 and 20,000 shares, respectively, of Company common
stock at market values of $2,075,683 and $280,000.  The Board of Directors
has authorized the Company, subject to market conditions and share price,
to purchase and retire up to $10 million of its common stock.  Through
February 1, 1999, 575,600 shares have been purchased at a market value of
$6,887,547.

The Company has never paid cash dividends and has no plans to do so in
fiscal 1999.
                                     
                                     

    ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

At December 31, 1998, the Company had an investment portfolio of fixed
income securities, excluding those classified as cash and cash equivalents,
of $12,100,711.  These securities, like all fixed income instruments, are
subject to interest rate risk and will decline in value if market interest
rates increase.  However, the Company has the ability to hold its fixed
income investments until maturity and therefore the Company would not
expect to recognize an adverse impact in income or cash flows.

The Company operates internationally, and thus is subject to potentially
adverse movements in foreign currency rate changes.  The Company does not
enter into foreign exchange forward contracts to reduce its exposure to
foreign currency rate changes on intercompany foreign currency denominated
balance sheet positions.  Historically, the effect of movements in the
exchange rates haS been immaterial to the consolidated operating results of
the Company.



                       Y2K AND EURO CURRENCY ISSUES

The Company must take steps to ensure that it is not adversely affected by
Y2K software failures which may arise in software applications where two-
year digits are used to define the applicable year. The Company is
conducting a review of all of its computer systems (information technology
as well as embedded systems) to identify those areas that could be affected
by Year 2000 noncompliance. The Company plans to complete the process of
upgrading those systems which may not be Y2K compliant by mid 1999 and does
not believe the cost of any such upgrades will be material. The Company is
in the process of developing contingency plans should systems fail. The
Company has also communicated with many of its suppliers and service
providers regarding compliance with Y2K requirements. As a result of such
inquiries, no significant deficiencies have been identified. The Company
will continue to monitor these third parties for Y2K compliance.

There can be no assurance, however, that there will not be a delay in, or
increased costs associated with, upgrading the Company's computer systems,
which could have a material adverse effect on the operations and financial
position of the Company. In addition, there can be no assurances that the
Company's customers and suppliers will not be adversely affected by their
own Y2K issues, which may indirectly adversely affect the Company. 

The Company has implemented new accounting and operational software at its
European subsidiary which accommodated the conversion on January 1, 1999 to
a common currency, the "euro," by members of the European Union.  The
software is also Y2K compliant.

     provide to Buyer copies of or allow Buyer access to the 
     following items within two (2) days from the execution of this

          the remainder of the Property;

               (ii) complete copies of all service and maintenance 
          contracts currently affecting the Property ("Other 
          Agreements");

               (iii) copies of all permits or authorizations, if 
          any, in Seller's possession, required to be issued by 
          any governmental body having jurisdiction in connection 
          with any state of facts or activity presently existing or 
          being carried on with respect to the Property;

               (iv) copies of all warranties and guaranties, if any,

          or any portion thereof ("Warranties");

               (v)  inventory of the Personal Property owned by the

     ("Current Uses") without being in violation of any zoning 
     classification, land use classification, environmental

     authority having legal jurisdiction or authority thereover.

          (c)  All utilities, including but not limited to

          (f)  Buyer's approval of the License Agreement, Parking 
     Easement and Management Agreement as defined in Sections XVIII 
     and XXV hereof.

     This Purchase Agreement shall be deemed terminated and neither party 
liable to the other herein unless Buyer affirmatively accepts or waives the 
foregoing conditions by paying to the Escrow Agent the Deposit by February 26, 
1999 at 12:01 p.m. as required by Section II.  Seller acknowledges that
Buyer's election not to purchase the Property may be based upon Buyer's 
unwillingness to accept the condition of the properties covered by the 2101 
Kennedy Option and the Phase II Option, including but not limited to 
environmental.  Notwithstanding the foregoing, Buyer may elect to terminate 
this Purchase Agreement between February 26, 1999 and the date of closing in

Section V hereof reveal contamination not previously known on February 26, 
1999, or (ii) a change in any item referred to in (b) above occurs between 
February 26, 1999 and the date of closing so as to prohibit the use of the 
Property for Current Uses.  Upon any such termination of this Purchase 
Agreement by Buyer, the Deposit (other than the interest earned thereon) shall
be returned to Buyer as provided in Section III hereof and all parties hereto 
shall be released from all duties and obligations to each other contained 
herein.

                            SECTION V

                 ENVIRONMENTAL AUDITS AND SURVEY

     A.   Environmental Audits.  Seller has provided to Buyer environmental 
reports ("Environmental Reports") for the Property at no cost or expense to 
Buyer which are described in Exhibit C hereto attached and that except for the 
Exhibit D information, to the best of Seller's knowledge, such material 
constitutes all of the environmental reports in Seller's possession or control.
Buyer shall have the right to do additional environmental audits and/or soil 
tests subject to the reasonable prior written approval of Seller regardless of 
the cost as long as Buyer pays for all of such costs; provided, however, no 
such additional testing shall be done beyond February 26, 1999 unless the 
testing is based on new information not previously known to Buyer.  Buyer
agrees to indemnify and hold Seller harmless from all mechanic's liens 
liability and other costs and expenses arising from Buyer's doing such 
additional environmental audits and/or soil tests.

     B.   Survey.  Seller has provided Buyer with a survey ("Survey") of the 
Property.

     C.   Copies of Documents.  To the extent not already done, Seller shall 
promptly deliver to Buyer or make available to Buyer copies of all soil tests, 
environmental audits, surveys and other documents relating to the physical 
properties of the Property which are within Seller's control and Buyer agrees 
to promptly deliver to Seller copies of all of such items which are within
Buyer's control.  Buyer will deliver to Seller, at the closing, copies of all 
the contents of the "RREEF Box" hereafter defined.
    
    D.   RREEF Box Documents.  The parties acknowledge that Seller has 
provided to Buyer an unopened box ("RREEF Box") allegedly containing due 
diligence materials for the Property prepared by RREEF, as hereafter defined.  
Attached hereto as Exhibit D is a list of the materials in the RREEF Box 
relating to the Environmental Reports of the Property.  Seller makes no
representations or warranties as to the accuracy of the contents of the RREEF 
Box nor shall any of Seller's representations and warranties regarding the 
sale of the Property or the sale of the properties covered by the 2101 Kennedy 
Option and/or the Phase II Option be in any manner considered based on such 
contents except for the Environmental Reports described in Exhibit D.


                           SECTION VI

                         TITLE EVIDENCE

     A.   Seller, at Seller's expense, will provide Buyer prior to February 
15, 1999 with a commitment(s) (the "Commitment") for an Owner's Policy of 
Title Insurance for the Property issued by Title.  Buyer shall pay at closing 
the premium for the actual title insurance policy, if any, to be purchased by 
Buyer.  The Commitment shall include appurtenant coverage for Buyer's rights
under the Parking Easement as not subordinate to any prior interest, unless 
approved by Buyer, waiver of standard exceptions, a zoning and comprehensive 
endorsements and a contiguity endorsement as to each of Parcel 1 and Parcel 2 
and shall include legible copies of all documents, maps, or plats set
forth therein as affecting the Property and shall be issued through Title in 
its capacity as a title insurance company by its local office or by its local 
agent (the "Title Company") situated in the county where the Property is 
located.  The Commitment shall be issued in the name of Buyer, Techne 
Corporation and Buyer's lender.

     B.   By February 26, 1999, Buyer shall deliver to Seller a written 
statement containing any objection Buyer has to the state of title, including 
Survey objections and objections to Permitted Encumbrances.  Buyer 
acknowledges that simultaneously with the closing, Seller will terminate the 
Declaration of Easement dated December 21, 1995, filed January 4, 1996, as 
Document No. 2665870 with Hennepin County Registrar of Titles office 
("Declaration"). If such statement of objection is not delivered by February 
26, 1999, title shall be deemed approved by Buyer except for Schedule B, 
Section 1 requirements of the commitment ("Requirements") which Seller agrees 
to satisfy at closing.  If any objection other than the Requirements is not 
cured or removed by February 26, 1999, Buyer, at its option, may, prior to
February 26, 1999, either (i) accept title as it is, subject to Seller's 
obligations to satisfy the Requirements; or (ii) terminate this Purchase 
Agreement.  Seller shall have no obligation to cure any of the Permitted 
Encumbrances.  Upon any such termination all parties shall be released from 
all duties or obligations contained herein and the Deposit (other than the
interest earned thereon) shall be returned to Buyer as provided for in 
Section III hereof.


                           SECTION VII

                          1031 EXCHANGE

     At either party's request, the other party agrees to cooperate with the 
requesting party in a deferred or simultaneous 1031 like kind exchange(s) of 
all or any portion of the Property as long as the other party is not required 
to take title to any other property or to incur any further cost, expense, 
liability or delay.


                          SECTION VIII

                WAIVER OF RIGHT OF FIRST REFUSAL

     If this Purchase Agreement is terminated pursuant to either Section IV 
(by failing to pay to Escrow Agent the Deposit by 12:01 p.m. on February 26, 
1999), or Section VI hereof, Buyer agrees that such termination shall 
constitute a waiver of its Right of First Refusal only with respect to a 
sale of the Property to RREEF (as hereafter defined) as hereinafter provided
and that Seller shall be free to sell the Property (along with Seller's 
interest in other properties which are the subject of option agreements of 
even date herewith between Seller and Buyer relating to 2101 Kennedy and 2001 
Kennedy and related parking areas) to RREEF Venture Capital Fund L.P., or a 
related or affiliated entity ("RREEF") provided such sale is consummated
prior to October 15, 1999.  Buyer agrees, not later than January 29, 1999, to 
execute an estoppel certificate in favor of RREEF with respect to the Lease 
for use by RREEF and to deliver the original of same to Title on or before 
January 29, 1999 to be held by Title in escrow pending RREEF's acquisition of 
title to the Property prior to October 15, 1999.  Title shall provide a copy 
of the same to Seller upon receipt but shall retain the original.  If this 
Purchase Agreement is not terminated, or, if it is and the RREEF transaction 
is not consummated by October 15, 1999, the original certificate shall be 
returned to Buyer.  This section shall survive the termination of this 
Purchase Agreement.


                           SECTION IX

                           WARRANTIES

     Seller warrants and represents to Buyer that the following statements

     the date of closing any deferred tax or assessment, including, 
     but not limited to, those referred to in Minnesota Statutes

     Agreement have been, or will be on or before the date of closing, 
     duly and validly authorized, executed and delivered by Seller and 
     the obligations of Seller hereunder and thereunder are or will 
     be valid and legally binding, and this Purchase Agreement and the 
     documents, instruments and agreements to be executed and delivered 
     by Seller pursuant to this Purchase Agreement are or will be upon 
     such execution and delivery enforceable against Seller in 
     accordance with their respective terms.

          (h)  Except as shown by the materials described in Exhibit C

     cure any violations of law or municipal ordinance, orders or

          (r)  Seller will execute such documents including indemnitees 
     as are necessary for Title to issue an early start endorsement for 
     Buyer and Buyer's lender; provided, however, such documents will 
     not guarantee payment by Buyer to Seller of any contract amounts.

               2201               $20,500,000.00

     None of the foregoing warranties shall be construed as a warranty 
     as to the sufficiency of parking, it being understood that parking 
     requirements are dependent on the usage of the Property by the Buyer.
     
     Except for the foregoing warranties, Buyer acknowledges that it 
     is purchasing the Property in its "as is" condition relying solely 
     on its knowledge of the Property in its capacity as tenant under 
     the Lease and on its inspection of the quantity and quality of the
     Property including the floor, the structural portions of the 
     Property and the roof.  The foregoing representations and 
     warranties will survive until December 31, 1999 ("Final Action 
     Date").  The parties agree that all actions commenced by Buyer 
     against Seller based on such representations and warranties
     shall be deemed time barred unless such actions have been commenced 
     prior to the Final Action Date, or such claims are based on fraud, 
     it being understood that except for claims based on fraud, Buyer 
     shall be deemed to have released Seller for any claims based on such
     representations and warranties unless an action based thereon is 
     commenced prior to Final Action Date.

Rejection or refusal to accept or the inability to deliver notice hereunder 
because of changed address of which no notice was given shall be deemed to 
be receipt of the notice, demand or request.  Any party shall have the right 
from time to time and at any time upon at least ten (10) days' written notice

                           SECTION XVI

                          CONDEMNATION

     In the event any portion of the Property is condemned or access thereto 
shall be taken, or in either case threatened, prior to the closing, and the 
taking renders the Property remaining unsuitable for the Buyer's current 
and/or anticipated use of the Property and Buyer notifies Seller in writing 
that it wishes to terminate this Purchase Agreement within thirty (30)
days after written notice to Buyer of such condemnation action, then this 
Purchase Agreement shall terminate, neither party to this Agreement shall have 
any further liability to the other parties (except for Buyer's indemnity in 
Section IV(a) hereof), and the Deposit (exclusive of any interest earned 
thereon) shall be returned to Buyer.

     If the Purchase Agreement is not terminated pursuant to the preceding 
sentence, the Purchase Price of the Property shall not be affected, it being 
agreed that if the award is paid prior to the closing of this transaction, 
such amount, insofar as it pertains to the Property, shall be held in escrow 
and delivered to Buyer at the time of closing; and if the award has not been
paid prior to the closing of this transaction, then at the closing Seller 
shall assign to Buyer all of its right, title and interest with respect to 
such award and shall further execute any other instrument requested by Buyer 
to assure that such award is paid to Buyer.  If Buyer fails to timely close 
the transaction and this agreement is terminated by Seller, any escrowed
condemnation proceeds will be paid to Seller.

     If Buyer does not terminate this Purchase Agreement, it shall have the 
right to contest the condemnation and/or the award resulting therefrom but 
such right shall terminate if Seller terminates this Purchase Agreement as a 
result of Buyer's default hereunder.  If this Purchase Agreement is not 
terminated, the parties shall cooperate in defending any such taking and/or
maximizing the amount of the award.  Neither party will take any action 
relating to the taking, without the other party's written consent prior to 
closing.

                           SECTION XVII

                DAMAGE OCCURRING PRIOR TO CLOSING

     If, prior to the closing date, all or any part of the Property is 
substantially damaged by fire, casualty, the elements or any other cause, 
Seller shall immediately give notice to Buyer of such fact and at Buyer's 
option (to be exercised with thirty (30) days after Seller's notice), this 
Purchase Agreement shall terminate, in which event neither party will have 
any further obligations under this Purchase Agreement and the Deposit
(exclusive of any interest earned thereon) shall be returned to Buyer.  
If Buyer fails to elect to terminate despite such damage, Seller (whether the 
damage is "substantial" or not) to the extent reasonably possible shall 
promptly commence to repair such damage or destruction to the Property's 
prior condition and to mitigate further damages using the quality of materials 
and workmanship existing prior to the date of the casualty.  If such damage 
shall be completely repaired prior to the closing date, then there shall be 
no reduction in the Purchase Price and Seller shall retain the proceeds of all 
insurance related to such damage.  If such damage shall not be completely 
repaired prior to the closing date, at Buyer's election, (i) Seller shall 
assign to Buyer all right to receive the proceeds of all insurance related to 
such damage, less costs incurred by Seller in mitigating damage or making 
repairs that are reimbursable by insurance then in force, and the Purchase 
Price shall remain the same, or (ii) the closing shall be postponed pending 
complete restoration of the damage by Seller.  For purposes of this Section,
