          **1.04.     No Conflict.**  The execution and delivery of this Agreement and the other Operative Documents and the consummation of the transactions contemplated herein and therein do not and will not violate or constitute a breach or default under Tri-Link's organizational documents or under the terms and conditions of any documents, agreements or other writings to which it is a party or by which any of its properties or assets might be bound, which violation, breach or default could reasonably be expected to have a Material Adverse Effect on Tri-Link.

Upon any such conversion being effected, each installment amount thereafter payable in respect of the Purchase Price shall be reduced, to be equal to: (a) such installment amount as would otherwise have been payable in respect thereof, less (b) the amount in respect of which such conversion was effected divided by the number of installment payments remaining to be made at the time such conversion was effected.  Teltronics covenants that all of the securities that are issued to Tri-Link upon conversion being effected hereunder will be duly and validly issued and will be fully paid and non-assessable.
          **4.06.     Royalty Commitment.**  For the period commencing on the closing and ending on the fifth anniversary thereof, Teltronics shall pay to Tri-Link royalties as follows:
7
                    (a)     Four percent (4%) of "Net Revenue" derived from following components of the Vortex Technology: Vortex S.E. Controller Software, Vortex S.E. QSAP, SLIC and POTS, PC-Phone and Analog PSTN Gateway, all as defined in Exhibit C attached hereto;
                    (b)     Two percent (2%) of "Net Revenue" derived from the following components of the Vortex Technology: Digital PSTN Gateway, H.323 WAN Gateway and BRI Gateway, all as defined in Exhibit C attached hereto.
                    For purposes of this Agreement "Net Revenue" means monies actually received by Teltronics in connection with the sale, licensing, distribution or other exploitation of the Vortex Technology (as delineated in Sections 4.07 (a) and (b) above), but shall exclude sales and use taxes, returns, refunds, rebates, and separately stated shipping and handling costs or separately stated maintenance, support, and engineering fees.  The term "Net Revenue" shall not include any monies received by Teltronics in connection with the sale, licensing, distribution or other exploitation of its own products and services (including those products and services that interface, integrate or are compliant with the Vortex Technology), whether in existence as of the date hereof or developed in the future, provided that such products or services do not incorporate, use or comprise (otherwise than by way of interfacing, integrating or being compliant with) the Vortex Technology (or any portion or portions thereof).  Teltronics presently has no intention of offering the Vortex Technology as part of an integrated system with any of its products or services, however, in the event that Teltronics proposes to offer the Vortex Technology as part of an integrated system, it will do so pursuant to a published price list with a separate line item designation for the Vortex Technology component of the system.  In the event Tri-Link disagrees with the pricing allocations reflected in such price list, the dispute resolution provisions of Article VIII shall apply.  Teltronics shall maintain adequate records to verify all reports and payments to be made to Tri-Link pursuant to this Section 4.06 for a period of two (2) years following the date of its termination.  Tri-Link shall have the right to select an independent certified public accountant mutually agreeable to the parties to inspect no more frequently than annually the records of Teltronics on reasonable notice and during regular business hours to verify the reports and payments required hereunder.  If such inspection should disclose any underreporting, Teltronics shall pay Tri-Link such amount within thirty (30) days of the conclusion of such inspection.  The entire cost of such inspection shall be borne by Tri-Link; provided however, that if Teltronics is determined by such inspection to have underpaid royalties by five percent (5%) or more, then the cost of such audit shall be borne by Teltronics.  Each royalty payment shall be accompanied by a statement setting forth in sufficient detail the basis upon which royalties were calculated.
          **4.07.     Tri-Link Employees.**  Teltronics shall assume and be liable for the accrued vacation pay and other statutory obligations owed by Tri-Link to its employees from August 1, 2002 through the Closing Time.  In the event Teltronics fails to purchase the Purchased Assets in accordance with Section 4.01 hereof, Teltronics shall not, prior to May 1, 2004, solicit or seek to employ any person who was an employee of Tri-Link at any time during the term of this Agreement.

Indemnity for Pre-Agreement Actions.**  From and after the date hereof, Tri-Link shall indemnify, defend and hold harmless Teltronics, and its shareholders, officers, directors, agents, representatives, and employees (Tri-Link is referred to in this Section 6.01 as the "Indemnifying Party," and the party to whom such indemnification obligation is owed is referred to in this Section 6.01 as the "Indemnified Party"), from and against, any and all actions, claims, losses, costs, liabilities, and expenses (including reasonable attorneys' fees) resulting from or arising out of any act or omission (occurring entirely before the date hereof) of Tri-Link or any officer, employee, representative or agent of Tri-Link (collectively "Pre-closing Claims") and will promptly reimburse any Indemnified Party for all Pre-closing Claims as incurred in connection with the investigation of, preparation for or defense of any pending or threatened action or proceeding (collectively, "Proceeding"), whether or not such Indemnified Party is a formal party to any such Proceeding. An Indemnified Party shall not, without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld) settle, compromise or consent to the entry of any judgment in any pending or threatened Proceeding in respect of which indemnification may be sought hereunder (whether or not the Indemnified Party is an actual or potential party to such Proceeding), provided, however, that the Indemnified Party may execute such settlement, compromise or consent to the entry of judgment in any pending or threatened Proceeding if same includes an unconditional release of the Indemnifying Party hereunder from all liability arising out of such Proceeding.
          **6.02.     Indemnity under this Agreement.**  From and after the date hereof, Tri-Link shall indemnify, defend and hold harmless Teltronics and its shareholders, officers, directors, agents, representatives, and employees, and Teltronics shall indemnify, defend and hold harmless Tri-Link and its shareholders, officers, directors, agents, representatives, and employees (Tri-Link or Teltronics, as applicable, shall be referred to in this Section 6.02 as the case may be as the "Indemnifying Party" and the party to whom such indemnification obligation is owed is referred to in this Section 6.02 as the "Indemnified Party"), from and against any and all actions, claims, losses, costs, liabilities, and expenses (including reasonable attorneys' fees) resulting from or arising out of any breach by the Indemnifying Party of any representation, warranty, or covenant by such Indemnifying Party in this Agreement (collectively, for purposes of this Section 6.02 only, "Claims") and will promptly reimburse any Indemnified Party for all Claims as incurred in connection with the investigation of, preparation for, or defense of any pending or threatened action or proceeding (collectively, "Proceeding"), whether or not such Indemnified Party is a formal party to any such Proceeding.
11
Notwithstanding the foregoing, the Indemnifying Party shall not be liable (a) for any amount paid by or on behalf of an Indemnified Party in settlement of any Claim without the consent of the Indemnifying Party (which consent shall not be unreasonably withheld), or (b) in respect of any losses, claims, damages, liabilities or expenses that a court of competent jurisdiction shall have determined by final judgment resulted primarily from the bad faith, negligence, or willful misconduct of an Indemnified Party.  An Indemnified Party shall not, without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld), settle, compromise or consent to the entry of any judgment in any pending or threatened Proceeding in respect of which indemnification may be sought hereunder (whether or not the Indemnified Party is an actual or potential party to such Proceeding), provided, however, that the Indemnified Party may execute such settlement, compromise or consent to the entry of judgment in any pending or threatened Proceeding if the same includes an unconditional release of the Indemnifying Party hereunder from all liability arising out of such Proceeding.

          **6.03.     Procedure.**  Promptly after a party to whom an indemnification obligation is owed hereunder (an "Indemnified Party") receives notice of the commencement of any Proceeding in respect of which indemnification may be sought hereunder, the Indemnified Party will notify the party that is obligated to indemnify hereunder (an "Indemnifying Party"); but the omission to so notify the Indemnifying Party shall not relieve the Indemnifying Party from any obligation hereunder unless, and only to the extent that, such omission results in the Indemnifying Party's forfeiture of substantive rights or defenses.  If any such Proceeding shall be brought against the Indemnified Party, the Indemnifying Party shall, upon written notice given reasonably promptly following the Indemnified Party's notice to the Indemnifying Party of any such Proceeding, be entitled to assume the defense thereof at its own expense with counsel chosen by the Indemnifying Party and reasonably satisfactory to the Indemnified Party; provided; however, that any Indemnified Party may, at its own expense, retain separate counsel to participate in such defense.
          **6.04.     Limitation on Liability.**  IN NO EVENT SHALL ANY PARTY HERETO BE LIABLE TO THE OTHER UNDER ANY THEORY OF TORT, CONTRACT, STRICT LIABILITY, OR OTHER LEGAL OR EQUITABLE THEORY FOR ANY LOST PROFITS, EXEMPLARY, PUNITIVE, SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES, EACH OF WHICH IS HEREBY EXCLUDED BY AGREEMENT OF THE PARTIES REGARDLESS OF WHETHER ANY PARTY HERETO HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES; PROVIDED, HOWEVER, THAT THE FOREGOING DOES NOT PRECLUDE ANY PARTY FROM BEING INDEMNIFIED AGAINST THIRD-PARTY CLAIMS UNDER ANY OF THE FOREGOING THEORIES OR FOR ANY OF THE FOREGOING DAMAGES.
          **6.05.     Sole Remedies.**  Teltronics and Tri-Link, on behalf of themselves and their respective Affiliates, agree that from and after the date hereof their sole remedies for any breach of any representation, covenant or warranty contained in this Agreement shall be limited to the right of indemnification as and to the extent set forth in this Article VI and waive any and all other remedies available at law or in equity, provided, however, that this limitation shall not apply in respect of any action brought for fraud.

Each party shall appropriately notify each employee, contractor, or agent to whom Information is disclosed that any such disclosures are made in confidence and shall be kept in confidence by such employee, contractor, or agent, and shall require any third party contractor or agent to sign a written agreement to maintain the confidentiality of the Information.

**ARTICLE VIIICONCILIATION AND ARBITRATION OF DISPUTES**
          **8.01.     Conciliation.**  In the event of any dispute, claim, question or disagreement arising out of or relating to this Agreement or any of the other Operative Documents, other than a matter for which a dispute resolution mechanism is specifically provided in this Agreement (including but not limited to a party's right to seek specific performance, judicial remedies or injunctive relief as provided in Sections 7.01 or 7.02 hereof) the parties shall use commercially reasonable efforts to settle such dispute, claim, question or disagreement.  To this effect, they shall consult and negotiate with each other, in good faith, and, recognizing their mutual interests, attempt to reach a just and equitable solution satisfactory to both parties.  If settlement is not otherwise possible within a reasonable time (not to exceed 20 days), the Chief Executive Officers, Chief Financial Officers, or other comparable senior executive officers of Teltronics and Tri-Link shall become involved in such efforts.
          **8.02.     Arbitration.**  If the parties do not reach a solution within a period of thirty (30) days after a matter is referred for conciliation, as provided above, the dispute shall be submitted to final and binding arbitration as the sole and exclusive remedy for such dispute.  Unless prohibited by applicable law, any claim shall be made by filing a written demand for arbitration within one (1) year following the conduct, act or other event or occurrence first giving rise to the claim; otherwise, the right to any remedy shall be deemed forever waived and lost.  The right and duty of the parties to this Agreement to resolve any disputes by arbitration shall be governed exclusively by, and arbitration shall take place according to the commercial arbitration
14
rules of the American Arbitration Association in effect as of the date hereof.  The arbitration shall be held at a mutually acceptable time and place in Toronto, Ontario, Canada.  Each party will select one arbitrator and the two so chosen will select a third, and failing selection of an arbitrator by either party or by the two chosen by the parties, the arbitrator(s) shall be selected from a panel of neutral arbitrators provided by the American Arbitration Association and shall be chosen by the striking method.  The parties each shall bear all of their own costs of arbitration; however, the fees of the arbitrators shall be divided equally between the parties.  The arbitrators shall have no authority to amend or modify the terms of this Agreement or any of the other Operative Documents.  Each party further agrees that, unless such a limitation is prohibited by applicable law, the other party shall not be liable for punitive or exemplary damages and the arbitrators shall have no authority to award the same.  The award or decision by a majority of the arbitrators shall be final and binding on the parties and may be enforced by judgment or order of any court located in the Province of British Columbia or the State of Florida (an "Arbitration Jurisdiction Court") or by any other court having jurisdiction over the parties.  The parties consent to the exercise of personal jurisdiction over them by any Arbitration Jurisdiction Court and to the propriety of venue of any Arbitration Jurisdiction Court for the purpose of carrying out this provision; and they waive any objections that they would otherwise have to the same.  No arbitration under this Agreement shall include, by consolidation, joinder or in any other manner, any Person other than the parties hereto or thereto and any Person in privity with or claiming through, in the right of or on behalf of such a party, unless both of the parties consent in writing.  To the extent permitted by applicable law, no issue of fact or law shall be given preclusive or collateral estoppel effect in any arbitration hereunder, except to the extent such issue may have been determined in another proceeding between the parties or between either of the parties and any person in privity with or claiming through, in the right of or on behalf of the other party.

          **8.03.     Provisional Remedies.**  Each party shall have the right to seek from an appropriate court provisional remedies including, but not limited to, temporary restraining orders or preliminary injunctions before, during or after arbitration.  Neither party need await the outcome of the arbitration before seeking provisional remedies.  Seeking any such remedies shall not be deemed to be a waiver of either party's right to compel arbitration.  Any such action shall be brought by the party in any Arbitration Jurisdiction Court.  The parties consent to the exercise of personal jurisdiction over them by courts located there and to the propriety of venue in such courts for the purpose of carrying out this provision; they waive any objections that they would otherwise have to the same; and they waive the right to have any such action decided by a jury.
**ARTICLE IXTERM AND TERMINATION**

Effect of Termination.**  In the event of the termination of this Agreement pursuant to Section 9.02, this Agreement shall become void and have no effect, except that the provisions of Articles VI, VII, VIII and X and any other provision necessary to give effect to such surviving provisions, shall survive any such termination.
