In no event, however, may the Closing be postponed by a party to a date later than July 24, 1996 by reason of failure of satisfaction of or failure to waive a condition or conditions to a party's obligations hereunder, unless all parties mutually agree in writing. 1.4 EXECUTION AND DELIVERY OF CLOSING DOCUMENTS.

Subject to the terms and conditions of this Article 9, Interphase hereby agrees to indemnify, defend and hold harmless Sellers and (unless the transactions contemplated hereby are consummated) Synaptel from and against all Damages (as hereinafter defined) asserted against or incurred by any or all of the Sellers and (if applicable) Synaptel by reason of or resulting from the existence of any facts or circumstances that would cause or render any representation or warranty contained herein, or in any agreement, document or instrument executed pursuant hereto or thereto, by Interphase to be untrue or incorrect, or the breach or failure of compliance of any covenant herein or therein contained by Interphase. For purposes of Section 9.2 "Damages" means all liabilities, losses, costs, damages, penalties, assessments, demands, claims, causes of action, including, without limitation, reasonable attorneys', accountants' and consultants' fees and expenses, court costs incurred by an indemnified party specifically referenced hereunder, and amounts that the indemnified party may incur or be required to pay in order to obtain the economic benefit of the transactions contemplated by this Agreement and the other agreements and instruments to be executed and delivered pursuant hereto, in each case less any tax benefits and any insurance or third party recoveries received by the indemnified party with respect to such item. 9.3 CONDITIONS OF INDEMNIFICATION. The obligations and liabilities of Interphase to the parties to be indemnified under Section 9.2 hereof with respect to claims resulting from the assertion of liability by third parties shall be subject to the following terms and conditions: (a) Promptly after receipt of notice of commencement of any action evidenced by service of process or other legal pleading, or within 30 days (or such shorter period as may be necessary in order that the rights of Interphase will not be prejudiced) after the assertion in writing of any other claim by a third party, the party to be indemnified shall give Interphase written notice thereof together with a copy of such claim, process or other legal pleading, and Interphase shall have the right to undertake the defense thereof by representatives of its own choosing and at its own expense; PROVIDED, HOWEVER, that the party to be indemnified may participate in the defense with counsel of its own choice and at its own expense. 8 (b) If Interphase, by the 30th day after its receipt of notice of any such claim (or, if earlier, by the 5th day preceding the day on which an answer or other pleading must be served in order to prevent judgment by default in favor of the person asserting such claim), does not notify the party to be indemnified that it has elected to defend against such claim, the party to be indemnified will have the right to undertake the defense, compromise or settlement of such claim on behalf of and for the account and risk of Interphase and at Interphase's expense, subject to the right of Interphase to assume the defense of such claims at any time prior to settlement, compromise or final determination thereof. The party to be indemnified will notify Interphase of any proposed settlement no later than three days before such settlement is effected. (c) Anything in this Section 9.3 to the contrary notwithstanding, Interphase shall not settle any claim without the consent of the party to be indemnified unless such settlement involves only the payment of money and the claimant provides to the party to be indemnified, in form and substance satisfactory to that party, a release from all liability in respect of such claim. If the settlement of the claim involves more than the payment of money, Interphase shall not settle the claim without the prior written consent of the party to be indemnified. (d) The party to be indemnified and Interphase will each cooperate with all reasonable requests of the other. (e) The failure of a party seeking indemnity hereunder to provide any notice required hereunder shall not relieve Interphase from any liability it would otherwise have hereunder, except to the extent that Interphase has been materially prejudiced thereby. 9.4 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. (a) Except as provided in (b) below or in SCHEDULE 4.1 hereto, all representations and warranties in this Agreement or in any agreement, document, certificate, schedule, exhibit or other instrument delivered by or on behalf of a party hereto and the indemnification obligations of the parties hereto relating to such representations and warranties shall survive for a period of 2 years after the Closing; provided, however, that with respect to any claim made by any party hereto on or before the expiration of the period, the representations and warranties that are the subject of such claim and indemnification obligations with respect thereto shall continue in effect, insofar as they relate or allegedly relate to the claim, until the claim is finally resolved. (b) Except as provided in SCHEDULE 4.1 all representations and warranties in this Agreement or in any agreement, document, certificate, schedule, exhibit or other instrument delivered by or on behalf of a party hereto which relate to administrative matters and the indemnification obligations of the parties hereto relating to such representations and warranties shall survive for a period of 3 1/2 years after the Closing; provided, however, that with respect to any claim made by any party hereto on or before the expiration of the period, the representations and warranties that are the subject of such claim and indemnification obligations with respect thereto shall continue in effect, insofar as they relate or allegedly relate to the claim, until the claim is finally resolved. 9 ARTICLE 10 TERMINATION 10.1 TERMINATION. This Agreement and the transactions contemplated hereby may be terminated at any time on or before the Closing: (a) by mutual written consent of the parties hereto; (b) by Interphase, if there has been a material misrepresentation or breach of warranty in the representations and warranties of Sellers herein or if there has been any material failure on the part of Sellers to comply with their obligations hereunder; (c) by Sellers if there has been a material misrepresentation or breach of warranty in the representations and warranties of Interphase herein or if there has been any material failure on the part of Interphase to comply with its obligations hereunder; (d) by Interphase or Sellers if the conditions precedent to their respective obligations to close the transactions contemplated by this Agreement have not been satisfied or waived by them at or before the Closing or if the transactions contemplated by this Agreement to be consummated on or before the Closing Date have not been consummated by July 24, 1996, unless such failure of satisfaction or consummation is due to the failure of the terminating party to perform or observe the covenants, agreements and conditions hereof to be performed or observed by it at or before the Closing; or (e) by Interphase or Sellers, if the consummation of the transactions contemplated hereby would violate any law, non-appealable final order, decree or judgment of any court or governmental body or agency having competent jurisdiction. No such termination shall affect any rights that the parties have against each other as a result of a material misrepresentation or breach of warranty by a party or a material failure by a party to comply with its obligations hereunder. If any of the Sellers purport to terminate this Agreement as to one or more but not all of them, Interphase shall have the right either to proceed with the consummation of this Agreement with respect to the non-terminating parties or to terminate this Agreement with respect to all parties and transactions contemplated hereby. 10 ARTICLE 11 MISCELLANEOUS 11.1 AMENDMENT.

The provisions of the earn-out (the "Earn-Out") are as follows: (a) The cash component of the Earn-Out will be $3,500,000, subject to adjustment as set forth in Paragraph 9 below. Upon attainment by Synaptel of the targets set forth herein, the cash component of the Earn-Out will be paid to the persons and in the percentages set forth in SCHEDULE 1.2 B of the Agreement (the "Beneficiaries"). The Earn-Out will be tied to achievement by Synaptel of the following Revenue (hereinafter defined) and Operating Income (hereinafter defined) targets during the following periods: Period Revenue Operating Income ------ ------- ---------------- 3rd quarter - 1996 $ 4,020,000 $ 320,000 4th quarter - 1996 $ 6,570,000 $ 1,200,000 1997 $ 25,000,000 $ 3,750,000 1998 $ 40,000,000 $ 7,150,000 (b) The cash component of the Earn-Out (the "Payment") will be paid by the later of either (i) 60 days after the target is attained or (ii) the last day for filing with the U.S. Securities and Exchange Commission the applicable Form 10-Q or 10-K Report for the period in which the target is attained. 2. The periods for which the Payment will be determined are the 3rd quarter of 1996, 4th quarter of 1996, fiscal 1997 and fiscal 1998 (together, the "Earn-Out Period"). 3. Interphase shall provide financing to Synaptel during the Earn-Out Period in accordance with the following schedule: Time Period Amount of Funding ----------- ----------------- 4. The cash component of the Earn-Out for each period stands by itself. There will be no carryovers or carrybacks. 5. All calculations of Synaptel's performance against the Earn-Out targets are to be calculated in accordance with United States generally accepted accounting principles ("GAAP"). (a) "Revenue" shall mean gross revenues less applicable returns and allowances, customs, insurance and freight, computed according to GAAP. (b) "Operating Income" shall mean revenues less cost of sales and operating expenses, computed according to GAAP. (c) Any sales by Interphase of Synaptel products, less commissions and selling costs, shall be treated as sales by Synaptel for purpose of computing Synaptel's performance against the Earn-Out targets. (d) Any sales by Synaptel of Interphase products shall be excluded from Synaptel's sales for purposes of computing Synaptel's performance against the Earn-Out targets. (e) However, for purposes of computing actual Operating Income performance against the Earn-Out targets described in Paragraph 1(a) above, the excess of the R&D tax credit over the R&D expenses eligible to be capitalized according to French tax laws shall be added to actual Operating Income. 6. In the event of a dispute between the parties with regard to the computation of Synaptel's performance against targets, each of Interphase and the Beneficiaries, at their own expense, shall appoint one representative from a "Big Six" accounting firm to resolve the dispute. If the two appointed representatives are unable to agree on a resolution to the dispute, the two representatives shall jointly agree on a third representative from a third "Big Six" accounting firm to resolve the dispute. The expense in connection with a third representative shall be divided equally between the parties. The resolution reached by the appointed representatives shall be final and binding on the parties. Disputes relating to the Earn-Out, other than disputes relating to the computation of Synaptel's performance against the Earn-Out targets, shall be settled by binding arbitration to be held in Geneva, Switzerland. All matters contained herein shall be governed by Texas law and all dispute resolutions, including arbitration, shall be conducted in English. 7. The cash component of the Earn-Out for each period is to be divided as set forth in Paragraphs 8 below, such that 65% is dependent upon the achievement of Revenue targets and 35% is dependent upon the achievement of Operating Income targets. These are to be paid independently of each other to reflect the view that while profitability of the target is important, growth is even more so. 8. The allocation of the cash component of the Earn-Out is to be spread among the periods as follows: Attributable to: ---------------- Period Total Revenue Operating Income ------ ----- ------- ---------------- 3rd quarter - 1996 $ 400,000 $ 260,000 $ 140,000 4th quarter - 1996 $ 600,000 $ 390,000 $ 210,000 1997 $1,600,000 $ 1,040,000 $ 560,000 1998 $ 900,000 $ 585,000 $ 315,000 Earn-Out Page 2 The early periods are weighted more heavily to emphasize the importance of building momentum early so that even greater growth can be achieved in the following years. 9. The Payment will individually be increased or decreased if performance is either more or less than the specific target set for each Revenue and Operating Income level on a period by period basis as follows Amount of targeted cash Performance level component to be awarded ----------------- ----------------------- less than 75% of target = zero 75% of target 50% of the Payment 76% thru 99% of target = the Payment is decreased 2% for every 1% below target 100% of target = 100% of the Payment 101% and more of target = the Payment is increased 2.5% for every 1% performance is above target The potential upside from exceeding targets is greater than the potential downside from underachieving targets. 10. Interphase shall have the right to buy out the remaining eligible cash component of the Earn-Out if Synaptel does not achieve at least 40% of any one target for any one period. For purposes of this provision, the 3rd and 4th quarters of 1996 shall be treated as one period. The purchase price of such buy-out shall equal 25% of the remaining cash component (determined by assuming future performance would have equaled 100% of target performance). The buy-out right must be exercised by written notice to the Sellers set forth in SCHEDULE 1.2 B within six months after the end of the period of underachievement. 11. Interphase, in its sole judgment and discretion, shall have the right from time to time to buy out any one individual, any combination of individuals or all individuals covered under the Earn-Out by paying cash for the full remaining balance (determined by assuming future performance would have equaled 100% of target performance) plus a 15% premium. 12. Interphase will cause the financial records to be maintained such that the Revenue and Operating Income, as herein defined, for Synaptel and its business will be determinable as if it had continued as a separate business throughout the entire term of the Earn-Out period unless Interphase shall have exercised its buy-out rights under paragraphs 10 or 11 herein. SCHEDULE 2.2 A 1. The provisions for the earn-out stock option grants are as follows: (a) Upon attainment by Synaptel of the targets set forth herein, grants will be made to the persons and in the proportions set forth in SCHEDULE 2.2 B and SCHEDULE 2.2 C of the Agreement (the "Option Beneficiaries"). The grants will be tied to achievement by Synaptel of the following Revenue (hereinafter defined) and Operating Income (hereinafter defined) targets (the "Targets") during the following periods: Period Revenue Operating Income ------ ------- ---------------- 3rd quarter - 1996 $ 4,020,000 $ 320,000 4th quarter - 1996 $ 6,570,000 $ 1,200,000 1997 $ 25,000,000 $ 3,750,000 1998 $ 40,000,000 $ 7,150,000 (b) Upon attainment by Synaptel of the Targets set forth in (a) above, Interphase will grant to the key Synaptel employees named and in the proportions set forth in SCHEDULE 2.2 B and SCHEDULE 2.2 C of the Agreement non-qualified stock options for up to 450,000 shares of Interphase Common Stock, subject to adjustment as set forth in Paragraph 7 below. The exercise price of the options will be $18.50, which is the same price used for the initial Purchase Price. The SCHEDULE 2.2 B options will be in accordance with the terms set forth in EXHIBITS 2.2 A-D of the Agreement, and the SCHEDULE 2.2 C options will be in accordance with the terms set forth in EXHIBIT 2.2 E of the Agreement. (c) The stock options will be granted by the later of either (i) 60 days after the target is attained or (ii) the last day for filing with the U.S. Securities and Exchange Commission the applicable Form 10-Q or 10-K Report for the period in which the Target is attained. 2. The stock options for each period stand by themselves. There will be no carryovers or carrybacks. 3. All calculations of Synaptel's performance against the Targets are to be calculated in accordance with United States generally accepted accounting principles ("(GAAP"). (a) "Revenue" shall mean gross revenues less applicable returns and allowances, customs, insurance and freight, computed according to GAAP. (b) "Operating Income" shall mean revenues less cost of sales and operating expenses, computed according to GAAP. (c) Any sales by Interphase of Synaptel products, less commissions and selling costs, shall be treated as sales by Synaptel for purposes of computing Synaptel's performance against the Targets. (d) Any sales by Synaptel of Interphase products shall be excluded from Synaptel's sales for purposes of computing Synaptel's performance against the Targets. (e) However, for purposes of computing actual operating Income performance against the Targets described in Paragraph 1(a) above, the excess of the R&D tax credit over the R&D expenses eligible to be capitalized according to French tax laws shall be added to actual Operating Income. 4. In the event of a dispute between the parties with regard to the computation of Synaptel's performance against Targets, each of Interphase and the Option Beneficiaries, at their own expense, shall appoint one representative from a "Big Six" accounting firm to resolve the dispute. If the two appointed representatives are unable to agree on a resolution to the dispute, the two representatives shall jointly agree on a third representative from a third "Big Six" accounting firm to resolve the dispute. The expense in connection with a third representative shall be divided equally between the parties. The resolution reached by the appointed representatives shall be final and binding on the parties. Disputes relating to the option grants, other than disputes relating to the computation of Synaptel's performance against the Targets, shall be settled by binding arbitration to be held in Geneva, Switzerland. All matters contained herein shall be governed by Texas law and all disputes resolutions, including arbitration, shall be conducted in English. 5. The stock options for each period are to be divided as set forth in Paragraph 6 below, such that 65% is dependent upon the achievement of Revenue targets and 35% is dependent upon the achievement of Operating Income targets. These are to be paid independently of each other to reflect the view that while profitability of the Target is important, growth is even more so. 6. The allocation of the stock options is to be spread among the periods as follows: Attributable to: Period Total Revenue Operating Income ------ ----- ------- ---------------- 3rd quarter-1996 27,000 18,000 9,000 4th quarter-1996 40,500 26,100 14,400 1997 157,500 102,600 54,900 1998 225,000 146,700 78,300 Grants are more heavily weighted to the later years to emphasize the longer term success of the combined entities. Stock Option Grant Page 2 7. The number of options will individually be increased or decreased if performance is either more or less than the specific Target set for each Revenue and Operating Income level on a period by period basis as follows: Amount of targeted Performance level stock options to be awarded ----------------- --------------------------- less than 75% of target = zero 75% of target = 50% of the number of options 76% thru 99% of target = the number of options is decreased 2% for every 1% below target 100% of target = 100% of the number of options 101% and more of target = the number of options is increased 2.5% for every 1% performance is above target. The potential upside from exceeding Targets is greater than the potential downside from underachieving Targets. 8. Interphase shall have the right to buy out the remaining stock options if Synaptel does not achieve at least 40% of any one Target for any one period. For purposes of this provision, the 3rd and 4th quarters of 1996 shall be treated as one period. The buy-out shall be effectuated by granting options equal to 25% of all remaining, eligible stock options (determined by assuming future performance would have equaled 100% of target performance). The buy-out right must be exercised by written notice to the persons set forth in SCHEDULE 2.2. B and SCHEDULE 2.2 C within six months after the end of the period of underachievement. 9. Interphase, in its sole judgment and discretion, shall have the right from time to time to buy out any one individual, any combination of individuals or all individuals covered in SCHEDULE 2.2. B and SCHEDULE 2.2 C by granting options for the full remaining balance (determined by assuming future performance would have equaled 100% of target performance) plus a 15% premium. 10. Interphase will cause the financial records to be maintained such that the Revenue and Operating Income, as herein defined, for Synaptel and its business will be determinable as if it had continued as a separate business throughout the entire term of the earn-out period unless Interphase shall have exercised its buy-out rights under paragraphs 8 or 9 herein.
