Security and Issuer. This statement relates to shares of common stock, par value $0.10 per share (the "Common Stock"), of DI Industries, Inc., a Texas corporation ("DI"). The principal executive office of DI is located at 450 Gears Road, Suite 625, Houston, Texas 77067. Item 2. Identity and Background. The persons filing this statement are (i) Lucien Flournoy, Maxine E. Flournoy, F.C. West, and Byron W. Fields, as directors (the "Directors") of Flournoy Drilling Company ("FDC") and (ii) FDC. The Directors are also shareholders of FDC. Lucien Flournoy and Maxine E. Flournoy are married, and together they own beneficially approximately 57.4% of the issued and outstanding stock of FDC. This Schedule 13D is filed on behalf of the Directors and FDC pursuant to (i) Rule 13d-1(f)(1) promulgated by the Securities and Exchange Commission (the "SEC") under the Securities Exchange Act of 1934, as amended (the "1934 Act"), and (ii) the Joint Filing Agreement dated effective February 6, 1997, between the Directors and FDC (the "Filing Agreement"). A copy of the Filing Agreement is attached as an Exhibit to this Schedule 13D. FDC's place of organization is the United States, its principal business is drilling oil and gas wells, and the address of its principal business and office is 1909 East Main Street, Alice, Texas 78332. All of the Directors are United States citizens. The business address for Lucien Flournoy, Maxine E. Flournoy, and Byron W. Fields is 1909 East Main Street, Alice, Texas 78332. The business address for F. C. West is 1907 East Main Street, Alice, Texas 78332. Lucien Flournoy is president and a director of both FDC and Flournoy Production Company, which are located at 1909 East Main Street, Alice, Texas 78332. He is also a director of DI. Maxine E. Flournoy is a director, and also serves as executive vice president, secretary, and treasurer, of both FDC and Flournoy Production Company. Byron W. Fields is vice president and a director of both FDC and Flournoy Production Company. F. C. West is vice president and a director of FDC, and also serves as Vice President of Drillers, Inc., a subsidiary of DI. Neither FDC nor any of the Directors has, during the last five (5) years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction which (i) resulted in FDC or any of the Directors being subject to a judgment, decree, or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws, or (ii) resulted in a finding of a violation with respect to such laws. Item 3. Source and Amount of Funds or Other Consideration. On January 31, 1997, FDC acquired 12,426,000 shares of the Common Stock in a transaction in which Drillers, Inc. purchased the drilling company assets of FDC in exchange for such Common Stock and the assumption by Drillers, Inc. of approximately $800,000 of FDC bank debt. The highest price at which such Common Stock was traded on the American Stock Exchange on January 31, 1997 was $3.1875 per share. By this measure, the aggregate value of the consideration paid for such Common Stock was approximately $39,607,875. 2 Item 4. Purpose of Transaction. The Common Stock was acquired as consideration for the sale by FDC of substantially all its drilling company assets to Drillers, Inc., as described in Item 3 above. Except as indicated otherwise in the next paragraph of this Item, neither FDC nor the Directors have at this time any plans or proposals which relate to or would result in: (a) The acquisition by any person of additional securities of, or the disposition of securities of, DI; (b) An extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving DI or any of its subsidiaries; (c) A sale or transfer of a material amount of assets of DI or any of its subsidiaries; (d) Any change in the present board of directors or management of DI, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (e) Any material change in the present capitalization or dividend policy of DI; (f) Any other material change in DI's business or corporate structure; (g) Changes in DI's charter, bylaws, or instruments corresponding thereto or other actions which may impede the acquisition of control of DI by any person; (h) Causing a class of securities of DI to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system or a registered or national securities association; (i) A class of equity securities of DI becoming eligible for termination of registration pursuant to Section 12(g)(4) of the 1934 Act; or (j) Any action similar to any of those enumerated above. As noted in Item 2 above, Lucien Flournoy currently serves as a director of DI. It is contemplated that, within the next 30 days, FDC will distribute the Common Stock held by it to its shareholders, pro rata in accordance with their ownership of FDC's stock. Each of the shareholders of FDC has signed a Shareholder's Agreement with Drillers, Inc. and DI pursuant to which one-half of the shares to be received by them in the contemplated dissolution of FDC 3 shall be subject to an obligation on the part of DI to issue additional shares if the shareholders hold value less than $2.00 per share on January 31, 1998. See Item 6 below. Item 5. Interest in Securities of the Issuer. (a) The Directors and FDC are the beneficial owners of 12,426,000 shares of the Common Stock. Such number of shares constitutes approximately 9.0% of the outstanding shares of the Common Stock. (b) FDC and the Directors, as directors of FDC, have shared power to direct the voting and disposition of such shares. (c) Other than FDC's January 31, 1997 acquisition of the 12,426,000 shares of Common Stock described above, during the past 60 days neither FDC nor any of the Directors has acquired any shares of the Common Stock. (d) No person other than FDC and the Directors is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any such shares. (e) Non-applicable. Item 6. Contracts, Arrangements, Understandings, or Relationships with Respect to Securities of the Issuer. 1. Joint Filing Agreement. On February 6, 1997, FDC and the Directors entered into a Filing Agreement in which each party agreed that this Schedule 13D is to be filed on behalf of each of them. Under the Filing Agreement, each party warranted that (i) it is eligible to use this Schedule 13D and (ii) it is responsible for the timely filing of this Schedule 13D, and any amendments thereon, and for the completeness and accuracy of the information concerning it contained in this Schedule 13D. Neither FDC nor any of the Directors are responsible for the completeness or accuracy of the information concerning any other party making this filing, unless such person knows or has reason to believe that such information is inaccurate. A copy of the Filing Agreement is attached as an Exhibit to this Schedule 13D, and this summary is qualified in its entirety by reference to the Exhibit. 2. Shareholders' Agreements. Each of the Directors, in their capacities as shareholders of FDC, is a party to a Shareholder's Agreement with DI and Drillers, Inc. The other shareholders of FDC are also parties to Shareholder's Agreements with DI and Drillers, Inc. The Shareholder's Agreements are all substantially identical, except as discussed below. 4 Each Shareholder's Agreement contains a provision under which each shareholder of FDC personally guarantees FDC's covenants, agreements, obligations, and liabilities under the indemnity provisions of the asset purchase agreement pursuant to which FDC sold substantially all of its drilling company assets to Drillers, Inc. Each shareholder's obligations under these provisions are capped at a dollar amount equal to the percentage which his shares of FDC common stock constitute relative to the total number of issued and outstanding shares of FDC common stock, multiplied by $10,000,000. Each Shareholder's Agreement also contains provisions pursuant to which one-half of the shares of Common Stock of DI to be received by them in the contemplated dissolution of FDC (as discussed above) shall be subject to an obligation on the part of DI to issue additional shares if the shareholders hold value less than $2.00 per share on January 31, 1998. In addition to these provisions, the Shareholder's Agreement signed by Lucien Flournoy provides that, for three (3) years following January 31, 1997, Lucien Flournoy shall not engage in competition in the business of drilling oil and gas wells in the geographic areas in which FDC conducted its oil and gas well drilling business within one (1) year prior to December 31, 1996. During such period, Lucien Flournoy also has agreed not to (i) request any present or future customer or supplier of FDC or Drillers, Inc. to curtail or cancel its business with Drillers, Inc., or (ii) disclose to any person any confidential information of FDC or Drillers, Inc., or (iii) induce or attempt to influence any employee of Drillers, Inc. to terminate his or her employment. Lucien Flournoy's Shareholder's Agreement also contains a provision under which DI agrees that it shall nominate Mr. Flournoy to serve on its board of directors. As noted above, Mr. Flournoy currently serves as a director of DI. The summary of the Shareholder's Agreements provided above is qualified in its entirety by reference to the copies of the Shareholder's Agreements attached as Exhibits to this Schedule 13D. Item 7.

WHEREAS, Buyer and Flournoy Drilling Company (the "Company"), a Texas corporation, are parties to an Asset Purchase Agreement dated December 31, 1996 (the "Asset Purchase Agreement"), which provides, upon the terms and subject to the conditions thereof, for the acquisition by Buyer of substantially all of the assets of the Company ("Assets"); WHEREAS, in order to induce Buyer to consummate the transactions contemplated by the Asset Purchase Agreement, Shareholder has agreed to execute and deliver this Agreement as provided in Section 8.4 of the Asset Purchase Agreement; NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements set forth herein, the parties hereto agree as follows: 1. Guaranty of Company Indemnification Obligation. (a) The Shareholder hereby irrevocably and unconditionally guarantees to Buyer the prompt and full discharge by the Company of all of the Company's covenants, agreements, obligations and liabilities under Section 9.1 of the Asset Purchase Agreement including, without limitation, the due and punctual payment of all amounts which are or may become due and payable by the Company thereunder when and as the same shall become due and payable (collectively, the "Company Obligations"), in accordance with the terms hereof. The Shareholder acknowledges and agrees that, with respect to the Company Obligations, such guaranty shall be a guaranty of payment and performance and not of collection and shall not be conditioned or contingent upon the pursuit of any remedies against the Company. If the Company shall default in the due and punctual performance of any Company Obligation, including the full and timely payment of any amount due and payable pursuant to any Company Obligation, the Shareholder will forthwith perform or cause to be performed such Company Obligation and will forthwith make full payment of any amount due with respect thereto at its sole cost and expense. The liabilities and obligations of the Shareholder pursuant to this Agreement are unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by: (1) any acceleration, extension, renewal, settlement, compromise, waiver or release in respect of any Company Obligation by operation of law or otherwise; (2) the invalidity or unenforceability, in whole or in part, of this Agreement or the Asset Purchase Agreement; 1 (3) any modification or amendment of or supplement to this Agreement or the Asset Purchase Agreement; (4) any change in the corporate existence, structure or ownership of Buyer or the Company, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting either of them or their assets; or (5) any other act, omission to act, delay of any kind by any party hereto or any other person, or any other circumstance whatsoever that might, but for the provisions of this Section 1(a), constitute a legal or equitable discharge of the obligations of the Shareholder hereunder. (b) The Shareholder hereby waives any right, whether legal or equitable, statutory or non-statutory, to require Buyer to proceed against or take any action against or pursue any remedy with respect to the Company or any other person or make presentment or demand for performance or give any notice of nonperformance before Buyer may enforce its rights hereunder against the Shareholder. (c) The Shareholder's obligations hereunder shall remain in full force and effect until the Company Obligations shall have been performed in full. If at any time any performance by any Person of any Company Obligation is rescinded or must be otherwise restored or returned, whether upon the insolvency, bankruptcy or reorganization of the Company or otherwise, the Shareholder's obligations hereunder with respect to such Company Obligation shall be reinstated at such time as though such Company Obligation had become due and had not been performed. (d) Upon performance by the Shareholder of any Company Obligation, the Shareholder shall be subrogated to the rights of Buyer against the Company with respect to such Company Obligation; provided, that the Shareholder shall not enforce any Company Obligation by way of subrogation against the Company while any Company Obligation is due and unperformed by the Company. (e) Pursuant to Section 9.3 of the Asset Purchase Agreement, notwithstanding any other provisions to the contrary in this Agreement, the Shareholder's liability under this Section 1 shall be limited to the sum of $3,404,000 cash or, if the Company so elects, shares of DI Common Stock with a total value of $3,404,000 at the last reported sale price of DI Common Stock on the American Stock Exchange averaged for the ten trading days prior to the date of payment of such indemnified amount. 2. DI's Obligation to Issue Additional Shares. DI shall issue to the Shareholder after the Determination Date (as defined below) the number of shares of DI's Common Stock, par value $0.10 (the "Common Stock"), issuable to the Shareholder, if any, under the terms and subject to the conditions set forth in this Section 2 (the "Additional Shares"). The number of Additional Shares issuable to the Shareholder shall be equal to the number of shares of Common Stock calculated by dividing (i) the Shortfall Amount by (ii) 2 the Average DI Stock Price during the Measurement Period, as such terms are hereafter defined. Any fractional share resulting from such calculation shall be rounded up to the nearest whole share. (a) The term "SHORTFALL AMOUNT" shall mean with respect to each Shareholder one-half of the positive difference, if any, between (i) the product of (x) $2.00, multiplied by (y) the number of Distributed Shares, minus (ii) the sum of (A) the gross proceeds of all Public Dispositions (as such term is hereinafter defined), (B) the gross proceeds of all Private Dispositions (as such term is hereinafter defined) and (C) the product of (x) the Average DI Stock Price during the Measurement Period, multiplied by (y) the number of Distributed Shares that remain beneficially owned by Shareholder as of 5:00 p.m. New York, New York time on the Determination Date. (b) The term "DISTRIBUTED SHARES" shall mean, with respect to each Shareholder, the number of shares of Common Stock distributed to such Shareholder by the Company as a liquidating distribution. (c) The term "DISPOSITION" shall mean and include a sale, assignment, pledge, gift, transfer or other conveyance of some or all (or any undivided interest in some or all) of the Common Stock, or any contract or option to make any such sale, assignment, pledge, transfer or conveyance. The term "PUBLIC DISPOSITION" shall mean a Disposition effected by the sale of all or any portion of the Distributed Shares on the American Stock Exchange or such other principal trading market on which the Common Stock is then publicly traded. A Public Disposition shall be deemed to occur on the date such transaction occurs rather than the settlement date thereof. The term "PRIVATE DISPOSITION" shall mean any Disposition of Distributed Shares that is not a Public Disposition, and does not result in the Shareholder retaining beneficial ownership of the Distributed Shares. As used in this Agreement, gross proceeds of a Private Disposition shall mean the greater of: (i) the fair market value of all consideration given by the transferee(s) in such Private Disposition, and (ii) the product of (A) the Average DI Stock Price during the ten Trading Days (hereinafter defined) immediately preceding the date of the Private Disposition multiplied by (B) the number of Distributed Shares transferred in such Private Disposition. (d) The term "AVERAGE DI STOCK PRICE" shall mean the average of the last reported sale price regular way of the Common Stock on the American Stock Exchange or other principal trading market on which the Common Stock is then publicly traded calculated for the number of Trading Days over which such average is to be computed, or if the principal market on which the Common Stock is then traded does not report prices on the basis of sale transactions, the average of the closing bid and ask prices for the Common Stock over the applicable number of Trading Days. (e) The term "MEASUREMENT PERIOD" shall mean the first ten Trading Days immediately prior to and including the Determination Date on which none of the Shareholders or their respective Affiliates shall have sold or offered for sale any shares of the Common Stock in any public securities market on which the Common Stock is then 3 traded. In the event that any of the Shareholders or their respective Affiliates have sold or offered for sale Common Stock on a Trading Day that would otherwise be included in the Measurement Period, such Trading Day shall be excluded from the Measurement Period and in substitution for such day there shall be added to the beginning of the Measurement Period the next preceding Trading Day on which no such sales or offers were made by any of the Shareholders or their respective Affiliates. For purposes of this paragraph (e), an offer of Common Stock shall be deemed to have occurred in connection with an underwritten public offering only from the period from and including the effective date of the registration statement for the offering through and including the closing date of such public offering. No offer of Common Stock shall be deemed to have occurred for purposes of this paragraph (e) with respect to Common Stock covered by a shelf registration statement under Rule 415 under the Securities Act except on days on which orders for sales of Common Stock have been placed by any Shareholder or their respective Affiliates on the American Stock Exchange or other principal securities market on which the Common Stock may then be publicly traded. (f) A "TRADING DAY" shall mean a day on which the Common Stock is traded on the American Stock Exchange, or the principal trading market on which the Common Stock is then publicly traded if other than the American Stock Exchange. (g) The "DETERMINATION DATE" shall mean the one year anniversary of the Closing Date under the Asset Purchase Agreement, unless the Shareholder shall have sold all of the Shares before such anniversary date, in which event the Determination Date shall be the next Trading Day following the final sale of Shares.

(m) The Shareholder agrees that he will not engage in a Disposition within the ten Trading Days immediately prior to the one year anniversary of the Closing Date. Shareholder also acknowledges and agrees that he may be requested not to make a Disposition for a period of time by DI because of requirements by underwriters of DI securities or as a requirement of the Securities Act. It is understood and agreed that the period shall not exceed 90 days. 3. Non-Competition. In order to allow Buyer and DI to realize the full benefit of their bargain in connection with the purchase of the Assets, Shareholder will not, at any time, for a period of three years following the Closing Date, directly or indirectly, acting alone or as a member of a partnership or as a holder of in excess of 5% of any security of any class, or as a consultant to or representative of, any corporation or other business entity, a. engage in any business in competition with the Business as conducted by the Company at the date hereof in those geographic areas in which such Business is conducted or has been conducted within one year prior to the date of this Agreement; or 5 b. request any present or future customer or supplier of the Company or of the Business as conducted by Buyer to curtail or cancel its business with Buyer; or c. unless otherwise required by law, disclose to any person, firm or corporation any details of organization or business affairs of the Company or the Business, any names of past or present customers of the Company or any other non-public information concerning the Business, the Company or the Assets; or d. induce or attempt to influence any employee of Buyer assigned to the conduct of the Business to terminate his or her employment. The Shareholder acknowledges that in the event the scope of the covenants set forth in this Section 3 is deemed to be too broad in any proceeding, the court may reduce such scope to that which it deems reasonable under the circumstances. The parties hereto agree and acknowledge that Buyer and DI would not have any adequate remedy at law for the breach or threatened breach by the Shareholder or any of his affiliates of the covenants and agreements set forth in this Section 3 and, accordingly, the Company further agrees that Buyer or DI may, in addition to the other remedies which may be available to them hereunder, file suit in equity to enjoin the Shareholder from such breach or threatened breach and consent to the issuance of injunctive relief hereunder. Shareholder understands and agrees that the act of Buyer and DI in entering into this Agreement and the Asset Purchase Agreement, and Buyer's and DI's covenants and payments hereunder, shall and do constitute sufficient consideration for Shareholder to agree not to compete against Buyer and DI as set out in this Section 3. Notwithstanding the foregoing, nothing herein shall restrain Shareholder from contracting for the services of third party drilling contractors for the drilling of oil and gas wells or from engaging in and exploring for and developing oil and gas properties for the account of the Shareholder or any of his affiliates. 4. Nomination to Board. DI agrees that it shall nominate Shareholder to serve on its Board of Directors as soon as practicable after the date hereof. 5. Representation of Shareholder.

If the Company shall default in the due and punctual performance of any Company Obligation, including the full and timely payment of any amount due and payable pursuant to any Company Obligation, the Shareholder will forthwith perform or cause to be performed such Company Obligation and will forthwith make full payment of any amount due with respect thereto at its sole cost and expense. The liabilities and obligations of the Shareholder pursuant to this Agreement are unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by: (1) any acceleration, extension, renewal, settlement, compromise, waiver or release in respect of any Company Obligation by operation of law or otherwise; (2) the invalidity or unenforceability, in whole or in part, of this Agreement or the Asset Purchase Agreement; 1 (3) any modification or amendment of or supplement to this Agreement or the Asset Purchase Agreement; (4) any change in the corporate existence, structure or ownership of Buyer or the Company, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting either of them or their assets; or (5) any other act, omission to act, delay of any kind by any party hereto or any other person, or any other circumstance whatsoever that might, but for the provisions of this Section 1(a), constitute a legal or equitable discharge of the obligations of the Shareholder hereunder. (b) The Shareholder hereby waives any right, whether legal or equitable, statutory or non-statutory, to require Buyer to proceed against or take any action against or pursue any remedy with respect to the Company or any other person or make presentment or demand for performance or give any notice of nonperformance before Buyer may enforce its rights hereunder against the Shareholder. (c) The Shareholder's obligations hereunder shall remain in full force and effect until the Company Obligations shall have been performed in full. If at any time any performance by any Person of any Company Obligation is rescinded or must be otherwise restored or returned, whether upon the insolvency, bankruptcy or reorganization of the Company or otherwise, the Shareholder's obligations hereunder with respect to such Company Obligation shall be reinstated at such time as though such Company Obligation had become due and had not been performed. (d) Upon performance by the Shareholder of any Company Obligation, the Shareholder shall be subrogated to the rights of Buyer against the Company with respect to such Company Obligation; provided, that the Shareholder shall not enforce any Company Obligation by way of subrogation against the Company while any Company Obligation is due and unperformed by the Company.

West ("Shareholder"). WHEREAS, Buyer and Flournoy Drilling Company (the "Company"), a Texas corporation, are parties to an Asset Purchase Agreement dated December 31, 1996 (the "Asset Purchase Agreement"), which provides, upon the terms and subject to the conditions thereof, for the acquisition by Buyer of substantially all of the assets of the Company ("Assets"); WHEREAS, in order to induce Buyer to consummate the transactions contemplated by the Asset Purchase Agreement, Shareholder has agreed to execute and deliver this Agreement as provided in Section 8.4 of the Asset Purchase Agreement; NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements set forth herein, the parties hereto agree as follows: 1. Guaranty of Company Indemnification Obligation. (a) The Shareholder hereby irrevocably and unconditionally guarantees to Buyer the prompt and full discharge by the Company of all of the Company's covenants, agreements, obligations and liabilities under Section 9.1 of the Asset Purchase Agreement including, without limitation, the due and punctual payment of all amounts which are or may become due and payable by the Company thereunder when and as the same shall become due and payable (collectively, the "Company Obligations"), in accordance with the terms hereof. The Shareholder acknowledges and agrees that, with respect to the Company Obligations, such guaranty shall be a guaranty of payment and performance and not of collection and shall not be conditioned or contingent upon the pursuit of any remedies against the Company. If the Company shall default in the due and punctual performance of any Company Obligation, including the full and timely payment of any amount due and payable pursuant to any Company Obligation, the Shareholder will forthwith perform or cause to be performed such Company Obligation and will forthwith make full payment of any amount due with respect thereto at its sole cost and expense. The liabilities and obligations of the Shareholder pursuant to this Agreement are unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by: (1) any acceleration, extension, renewal, settlement, compromise, waiver or release in respect of any Company Obligation by operation of law or otherwise; (2) the invalidity or unenforceability, in whole or in part, of this Agreement or the Asset Purchase Agreement; (3) any modification or amendment of or supplement to this Agreement or the Asset Purchase Agreement; 1 (4) any change in the corporate existence, structure or ownership of Buyer or the Company, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting either of them or their assets; or (5) any other act, omission to act, delay of any kind by any party hereto or any other person, or any other circumstance whatsoever that might, but for the provisions of this Section 1(a), constitute a legal or equitable discharge of the obligations of the Shareholder hereunder. (b) The Shareholder hereby waives any right, whether legal or equitable, statutory or non-statutory, to require Buyer to proceed against or take any action against or pursue any remedy with respect to the Company or any other person or make presentment or demand for performance or give any notice of nonperformance before Buyer may enforce its rights hereunder against the Shareholder. (c) The Shareholder's obligations hereunder shall remain in full force and effect until the Company Obligations shall have been performed in full. If at any time any performance by any Person of any Company Obligation is rescinded or must be otherwise restored or returned, whether upon the insolvency, bankruptcy or reorganization of the Company or otherwise, the Shareholder's obligations hereunder with respect to such Company Obligation shall be reinstated at such time as though such Company Obligation had become due and had not been performed. (d) Upon performance by the Shareholder of any Company Obligation, the Shareholder shall be subrogated to the rights of Buyer against the Company with respect to such Company Obligation; provided, that the Shareholder shall not enforce any Company Obligation by way of subrogation against the Company while any Company Obligation is due and unperformed by the Company. (e) Pursuant to Section 9.3 of the Asset Purchase Agreement, notwithstanding any other provisions to the contrary in this Agreement, the Shareholder's liability under this Section 1 shall be limited to the sum of $1,000,000 cash or, if the Company so elects, shares of DI Common Stock with a total value of $1,000,000 at the last reported sale price of DI Common Stock on the American Stock Exchange averaged for the ten trading days prior to the date of payment of such indemnified amount. 2. DI's Obligation to Issue Additional Shares. DI shall issue to the Shareholder after the Determination Date (as defined below) the number of shares of DI's Common Stock, par value $0.10 (the "Common Stock"), issuable to the Shareholder, if any, under the terms and subject to the conditions set forth in this Section 2 (the "Additional Shares"). The number of Additional Shares issuable to the Shareholder shall be equal to the number of shares of Common Stock calculated by dividing (i) the Shortfall Amount by (ii) the Average DI Stock Price during the Measurement Period, as such terms are hereafter defined. Any fractional share resulting from such calculation shall be rounded up to the nearest whole share. 2 (a) The term "SHORTFALL AMOUNT" shall mean with respect to each Shareholder one-half of the positive difference, if any, between (i) the product of (x) $2.00, multiplied by (y) the number of Distributed Shares, minus (ii) the sum of (A) the gross proceeds of all Public Dispositions (as such term is hereinafter defined), (B) the gross proceeds of all Private Dispositions (as such term is hereinafter defined) and (C) the product of (x) the Average DI Stock Price during the Measurement Period, multiplied by (y) the number of Distributed Shares that remain beneficially owned by Shareholder as of 5:00 p.m. New York, New York time on the Determination Date.

The term "PUBLIC DISPOSITION" shall mean a Disposition effected by the sale of all or any portion of the Distributed Shares on the American Stock Exchange or such other principal trading market on which the Common Stock is then publicly traded. A Public Disposition shall be deemed to occur on the date such transaction occurs rather than the settlement date thereof. The term "PRIVATE DISPOSITION" shall mean any Disposition of Distributed Shares that is not a Public Disposition, and does not result in the Shareholder retaining beneficial ownership of the Distributed Shares. As used in this Agreement, gross proceeds of a Private Disposition shall mean the greater of: (i) the fair market value of all consideration given by the transferee(s) in such Private Disposition, and (ii) the product of (A) the Average DI Stock Price during the ten Trading Days (hereinafter defined) immediately preceding the date of the Private Disposition multiplied by (B) the number of Distributed Shares transferred in such Private Disposition. (d) The term "AVERAGE DI STOCK PRICE" shall mean the average of the last reported sale price regular way of the Common Stock on the American Stock Exchange or other principal trading market on which the Common Stock is then publicly traded calculated for the number of Trading Days over which such average is to be computed, or if the principal market on which the Common Stock is then traded does not report prices on the basis of sale transactions, the average of the closing bid and ask prices for the Common Stock over the applicable number of Trading Days. (e) The term "MEASUREMENT PERIOD" shall mean the first ten Trading Days immediately prior to and including the Determination Date on which none of the Shareholders or their respective Affiliates shall have sold or offered for sale any shares of the Common Stock in any public securities market on which the Common Stock is then traded. In the event that any of the Shareholders or their respective Affiliates have sold or offered for sale Common Stock on a Trading Day that would otherwise be included in the Measurement Period, such Trading Day shall be excluded from the Measurement Period and in substitution for such day there shall be added to the beginning of the 3 Measurement Period the next preceding Trading Day on which no such sales or offers were made by any of the Shareholders or their respective Affiliates. For purposes of this paragraph (e), an offer of Common Stock shall be deemed to have occurred in connection with an underwritten public offering only from the period from and including the effective date of the registration statement for the offering through and including the closing date of such public offering. No offer of Common Stock shall be deemed to have occurred for purposes of this paragraph (e) with respect to Common Stock covered by a shelf registration statement under Rule 415 under the Securities Act except on days on which orders for sales of Common Stock have been placed by any Shareholder or their respective Affiliates on the American Stock Exchange or other principal securities market on which the Common Stock may then be publicly traded. (f) A "TRADING DAY" shall mean a day on which the Common Stock is traded on the American Stock Exchange, or the principal trading market on which the Common Stock is then publicly traded if other than the American Stock Exchange. (g) The "DETERMINATION DATE" shall mean the one year anniversary of the Closing Date under the Asset Purchase Agreement, unless the Shareholder shall have sold all of the Shares before such anniversary date, in which event the Determination Date shall be the next Trading Day following the final sale of Shares.
