(b)                                 Holdings Restrictions.  Holdings agrees that it will not knowingly take or fail to take, or permit any Holdings Affiliate to knowingly take or fail to take, any action where such action or failure to act would be inconsistent with any material, information, covenant or representation that relates to facts or matters related to Holdings (or any Holdings Affiliate) or within the control of Holdings and is contained in an Officer’s Certificate, Tax Opinion  or Supplemental Tax Opinion (except where such material, information, covenant or representation was not previously disclosed to Holdings) other than as permitted in this Section 4.2.  For this purpose an action is considered inconsistent with a representation if the representation states that there is no plan or intention to take such action.  Holdings agrees that it will not take (and it will cause the Holdings Affiliates to refrain from taking) any position on a Tax Return that is inconsistent with the treatment of the Separation and Distribution as transactions in which no income, gain, or loss is recognized pursuant to sections 355 and 368(a)(1)(D) of the Code.

(c)                                  Certain Holdings Actions Following the Distribution.  Holdings agrees that, during the two (2) year period following the Distribution, without first obtaining, at Holdings’ own expense, a private letter ruling (a “PLR”) from the IRS or supplemental opinion from Tax Adviser that such action will not result in Separation Taxes (a “Supplemental Tax Opinion”), unless JDSU and Holdings agree otherwise in writing, Holdings shall not (1) sell all or substantially all of the assets of Holdings or any Holdings Affiliate , (2) merge Holdings, or any Holdings Affiliate with another entity, without regard to which party is the surviving entity (other than a merger with another entity within the Holdings Group), (3) transfer any assets of Holdings or Holdings Affiliate in a transaction described in section 351of the Code (other than a transfer to a corporation which files a consolidated return with Holdings and which is wholly-owned, directly or indirectly, by Holdings) or subparagraph (C) or (D) of section 368(a)(1) of the Code, (4) issue stock of Holdings or any Holdings Affiliate (or any instrument that is convertible or exchangeable into any such stock) in an acquisition or public or private offering (excluding any issuance pursuant to the exercise of employee stock options or other employment related arrangements having customary terms and conditions and that satisfy the requirements of Treasury Regulations section 1.355-7(d)(8), or any successor provision thereto), or (5) facilitate or otherwise participate in any acquisition of stock in Holdings that would result in any shareholder owning five percent (5%) or more of the outstanding stock of Holdings.  Holdings (or any Holdings Affiliate) shall only undertake any of such actions after JDSU’s receipt of such Supplemental Tax Opinion and pursuant to the terms and conditions of any such Supplemental Tax Opinion or as otherwise consented to in writing in advance by JDSU; provided, however, that if Holdings contemplates entering into a transaction described in this section and Holdings acknowledges in writing that it would have sole liability for any Separation Taxes under Section 4.1(b) that might arise from such transaction and can demonstrate to the

11

reasonable satisfaction of JDSU that it can satisfy its liability for any such Separation Taxes, JDSU shall consent to Holdings’ entering into such transaction without further restriction; and provided, further, that in the event that JDSU completes a transaction that results in a tax being imposed on JDSU under Section 355(e) of the Code,  after such completion, Holdings shall no longer be subject to the restrictions under clause (4) and clause (5) of the previous sentence.  The Parties hereby agree that they will act in good faith to take all reasonable steps necessary to amend this Section 4.2(c), from time to time, by mutual agreement, to (i) add certain actions to the list contained herein, or (ii) remove certain actions from the list contained herein, in either case, in order to reflect any relevant change in law, regulation or administrative interpretation occurring after the date of this Agreement.

(d)                                 Notice of Specified Transactions.  Not later than three (3) days after the public announcement regarding any of the transactions described in Section 4.2(c) (including a public announcement regarding Holdings’ intent to enter into any such transaction) Holdings shall provide written notice of such transaction to JDSU.

4.3                               Transfer Taxes.  JDSU and Holdings each shall be responsible for any Transfer Taxes incurred by the JDSU Group and the Holdings Group, respectively, as a result of the Contribution. If, under applicable Law, both the JDSU Group and the Holdings Group are liable for Transfer Taxes resulting from the Contribution, then JDSU and Holdings shall be equally responsible for such Transfer Taxes.

4.4                               Allocation of Tax Items.  All Tax computations for (1) any Pre-Distribution Periods ending on the Distribution Date and (2) the immediately following taxable period of Holdings or any Holdings Affiliate, shall be made pursuant to the principles of section 1.1502-76(b) of the Treasury Regulations or of a corresponding provision under the laws of other jurisdictions, as reasonably determined by JDSU, taking into account all reasonable suggestions made by Holdings with respect thereto.  Any Tax Items relating to the Separation and Distribution shall be treated, to the extent permitted, as extraordinary items described in section 1.1502-76(b)(2)(ii)(C) of the Treasury Regulations and shall (to the extent occurring on or prior to the Distribution Date) be allocated to Pre- Distribution Periods, and any Taxes related to such items shall be treated under section 1.1502-76(b)(2)(iv) of the Treasury Regulations as relating to such extraordinary item and shall (to the extent occurring on or prior to the Distribution Date) be allocated to Pre-Distribution Periods.

4.5                               Allocation of Tax Assets.

(a)                                 In General.  In connection with the Distribution, JDSU and Holdings have set forth on SCHEDULE 4.5(A) the Tax Assets allocated to JDSU and Holdings, and each of JDSU and Holdings agrees that each shall prepare all Tax Returns in a manner consistent with such allocation, unless otherwise required by law.  The parties hereby agree that to the extent that Tax Assets are not shown in SCHEDULE 4.5(A), such Tax Assets were incurred by JDSU and shall remain with JDSU.

(b)                                 Earnings and Profits.  JDSU will advise Holdings in writing of the decrease in JDSU earnings and profits attributable to the Distribution under section 312(h) of the Code on or before the first anniversary of the Distribution Date; provided, however, that JDSU shall provide Holdings with estimates of such amounts (determined in accordance with past practice) prior to such anniversary as reasonably requested by Holdings.

12

Article V

EMPLOYEE WAGES

At JDSU’s request, the Holdings Group shall assume the Form W-2 and Form W-3 reporting obligations (including the filing of all forms necessary to comply with magnetic media reporting requirements) of JDSU with respect to any employee of the Holdings Business that Holdings or any Holdings Affiliate employs during the calendar year which includes the Distribution Date consistent with the procedures set forth in section 5 of Rev. Proc. 2004-53, 2004-34 I.R.B. 320.

Article VI

INDEMNIFICATION

6.1                               In General.  JDSU and each member of the JDSU Group shall jointly and severally indemnify Holdings, each Holdings Affiliate, and their respective directors, officers and employees, and hold them harmless from and against any and all Taxes for which JDSU or any JDSU Affiliate is liable under this Agreement and any loss, cost, damage or expense, including reasonable attorneys’ fees and costs, that is attributable to, or results from, the failure of JDSU, any JDSU Affiliate or any director, officer or employee to make any payment required to be made under this Agreement.  Holdings and each member of the Holdings Group shall jointly and severally indemnify JDSU, each JDSU Affiliate, and their respective directors, officers and employees, and hold them harmless from and against any and all Taxes for which Holdings or any Holdings Affiliate is liable under this Agreement and any loss, cost, damage or expense, including reasonable attorneys’ fees and costs, that is attributable to, or results from, the failure of Holdings, any Holdings Affiliate or any director, officer or employee to make any payment required to be made under this Agreement.

6.2                               Inaccurate or Incomplete Information.  JDSU and each member of the JDSU Group shall jointly and severally indemnify Holdings, each Holdings Affiliate, and their respective directors, officers and employees, and hold them harmless from and against any cost, fine, penalty, or other expense of any kind attributable to the failure of JDSU or any JDSU Affiliate in supplying Holdings or any Holdings Affiliate with inaccurate or incomplete information, in connection with the preparation of any Tax Return.  Holdings and each member of the Holdings Group shall jointly and severally indemnify JDSU, each JDSU Affiliate, and their respective directors, officers and employees, and hold them harmless from and against any cost, fine, penalty, or other expenses of any kind attributable to the failure of Holdings or any Holdings Affiliate in supplying JDSU or any JDSU Affiliate with inaccurate or incomplete information, in connection with the preparation of any Tax Return.

6.3                               No Indemnification for Tax Items.  Nothing in this Agreement shall be construed as a guarantee of the existence or amount of any loss, credit, carryforward, basis or other Tax Item, whether past, present or future, of JDSU, any JDSU Affiliate, Holdings or any Holdings Affiliate.  In addition, for the avoidance of doubt, for purposes of determining any amount owed between the parties hereto, all such determinations shall be made without regard to any financial accounting tax asset or liability or other financial accounting items.

Article VII

PAYMENTS

7.1                               Estimated Tax Payments.  Not later than ten (10) business days after each Estimated Tax Installment Date with respect to a taxable period for which a Consolidated Return or a Combined

13

Return that includes a Holdings Separate Tax Amount will be filed, Holdings shall pay to JDSU on behalf of the Holdings Group an amount equal to the amount of any estimated Holdings Separate Tax Amount.

7.2                               True-Up Payments.  Not later than ten (10) business days after filing a Tax Return, Holdings shall pay to JDSU, or JDSU shall pay to Holdings, as appropriate, an amount equal to the difference, if any, between the Holdings Separate Tax Amount and the aggregate amount paid by Holdings with respect to such period under Section 7.1.

7.3                               Redetermination Amounts.  In the event of a redetermination of any Tax Item reflected on any Consolidated Return or Combined Return (other than Tax Items relating to Separation Taxes), as a result of a refund of Taxes paid, a Final Determination or any settlement or compromise with any Taxing Authority which in any such case would affect the Holdings Separate Tax Amount, JDSU shall prepare a revised pro forma Tax Return in accordance with Section 2.4(b) for the relevant taxable period reflecting the redetermination of such Tax Item as a result of such refund, Final Determination, settlement or compromise.  Holdings shall pay to JDSU, or JDSU shall pay to Holdings, as appropriate, an amount equal to the difference, if any, between the Holdings Separate Tax Amount reflected on such revised pro forma Tax Return and the Holdings Separate Tax Amount for such period as originally computed pursuant to this Agreement.

7.4                               Payments of Refunds and Credits.  If one party receives a refund or credit of any Tax to which the other party is entitled pursuant to Section 3.4, the party receiving such refund or credit shall pay to the other party the amount of such refund or credit pursuant to Section 7.5.

7.5                               Payments Under This Agreement.  In the event that one party (the “Owing Party”) is required to make a payment to another party (the “Owed Party”) pursuant to this Agreement, then such payments shall be made according to this Section 7.5.

(a)                                 In General.  All payments shall be made to the Owed Party or to the appropriate Taxing Authority as specified by the Owed Party within the time prescribed for payment in this Agreement, or if no period is prescribed, within ten (10) days after delivery of written notice of payment owing together with a computation of the amounts due.

(b)                                 Treatment of Payments.  Unless otherwise required by any Final Determination, the parties agree that any payments made by one party to another party pursuant to this Agreement (other than (i) payments for the Holdings Separate Tax Amount for the Post-Distribution Period, (ii) payments of After Tax Amounts pursuant to Section 7.5(d), and (iii) payments of interest pursuant to Section 7.5(e)) shall be treated for all Tax purposes as nontaxable payments (dividend distributions or capital contributions, as the case may be) made immediately prior to the Distribution and, accordingly, as not includible in the taxable income of the recipient or as deductible by the payor.

(c)                                  Prompt Performance.  All actions required to be taken (including payments) by any party under this Agreement shall be performed within the time prescribed for performance in this Agreement, or if no period is prescribed, such actions shall be performed promptly.

(d)                                 After Tax Amounts.  If pursuant to a Final Determination it is determined that the receipt or accrual of any payment made under this Agreement (other than payments of interest pursuant to Section 7.5(e)) is subject to any Tax, the party making such payment shall be liable for (a) the After Tax Amount with respect to such payment and (b) interest at the rate described in Section 7.5(e) on the amount of such Tax from the date such Tax accrues through the date of payment of such After Tax Amount.  A party making a demand for a payment pursuant to this Agreement and for a payment of an After Tax Amount with respect to such payment shall separately specify and compute such After Tax

14

Amount.  However, a party may choose not to specify an After Tax Amount in a demand for payment pursuant to this Agreement without thereby being deemed to have waived its right subsequently to demand an After Tax Amount with respect to such payment.

(e)                                  Interest.  Payments pursuant to this Agreement that are not made within the period prescribed in this Agreement (the “Payment Period”) shall bear interest for the period from and including the date immediately following the last date of the Payment Period through and including the date of payment at a per annum rate equal to the applicable rate under Section 6621 of the Code.  Such interest will be payable at the same time as the payment to which it relates and shall be calculated on the basis of a year of three hundred sixty-five (365) days and the actual number of days for which due.

Article VIII

TAX PROCEEDINGS

8.1                               In General.  Except as otherwise provided in this Agreement, the party responsible for preparing and filing a Tax Return pursuant to Article II (the “Filing Party”) shall have the exclusive right, in its sole discretion, to control, contest, and represent the interests of JDSU, any JDSU Affiliate, Holdings, and/or any Holdings Affiliate in any Audit relating to such Tax Return and to resolve, settle or agree to any deficiency, claim or adjustment proposed, asserted or assessed in connection with or as a result of any such Audit; provided, however, that for purposes of this Section 8, Holdings shall be treated as the Filing Party for all Tax Returns of foreign Holdings Affiliates.  The Filing Party’s rights shall extend to any matter pertaining to the management and control of an Audit, including execution of waivers, choice of forum, scheduling of conferences and the resolution of any Tax Item.  Any costs incurred in handling, settling, or contesting an Audit shall be borne by the Filing Party.

8.2                               Participation of non-Filing Party.  Except as provided in Section 8.4, the non-Filing Party shall, at its own expense, have control over decisions to resolve, settle or otherwise agree to any deficiency, claim or adjustment with respect to any Sole Responsibility Item.

8.3                               Notice.  Within ten (10) days after a party receives written notice of a proposed Audit adjustment that may give rise to an indemnification obligation under this Agreement, such party shall give notice to the other party of such issue (such notice shall contain factual information, to the extent known, describing any asserted tax liability in reasonable detail), and shall forward to the other party copies of all notices and material communications with any Taxing Authority relating to such issue.  Notwithstanding any provision in Section 9.12 to the contrary, if a party to this Agreement fails to provide the other party notice as required by this Section 8.3, and the failure results in a detriment to the other party then any amount which the other party is otherwise required to pay pursuant to this Agreement shall be reduced by the amount of such detriment.

8.4                               Control of Separation Tax Proceedings.   JDSU shall have the exclusive right, in its sole discretion, to control, contest, and represent the interests of JDSU, any JDSU Affiliate, Holdings, and/or any Holdings Affiliate in any Audits relating to Separation Taxes and to resolve, settle or agree to any deficiency, claim or adjustment proposed, asserted or assessed in connection with or as a result of any such Audit.  JDSU’s rights shall extend to any matter pertaining to the management and control of such Audit, including execution of waivers, choice of forum, scheduling of conferences and the resolution of any Tax Item.  Holdings may assume sole control of any Audits relating to Separation Taxes if it acknowledges in writing that it has sole liability for any Separation Taxes under Section 4.1(b) that might arise in such Audit and can demonstrate to the reasonable satisfaction of JDSU that it can satisfy its liability for any such Separation Taxes.  If Holdings is unable to demonstrate to the reasonable satisfaction of JDSU that it will be able to satisfy its liability for such Separation Taxes, but

15

acknowledges in writing that it has sole liability for any Separation Taxes under Section 4.1(b), Holdings and JDSU shall have joint control over the Audit.

Article IX

MISCELLANEOUS PROVISIONS

9.1                               Corporate Power; Facsimile Signatures.

9.2                               Cooperation and Separation of Information.

(a)                                 Cooperation.  Holdings and JDSU shall each cooperate fully (and each shall cause its respective affiliates to cooperate fully) with all reasonable requests from another party for information and materials not otherwise available to the requesting party in connection with the preparation and filing of Tax Returns, claims for refund, and Audits concerning issues or other matters covered by this Agreement or in connection with the determination of a liability for Taxes or a right to a refund of Taxes.  Such cooperation shall include:

(b)                                 Retention of Records.  Any party that is in possession of documentation of JDSU (or any JDSU Affiliate) or Holdings (or any Holdings Affiliate) relating to the Holdings Business, including books, records, Tax Returns and all supporting schedules and information relating thereto (the “Holdings Business Records”) shall retain such Holdings Business Records for a period of seven (7) years following the Separation Date.  Thereafter, any party wishing to dispose of Holdings Business Records in its possession (after the expiration of the applicable statute of limitations), shall provide written notice to the other party describing the documentation proposed to be destroyed or disposed of sixty (60) business days prior to taking such action.  The other party may arrange to take delivery of any or all of the documentation described in the notice at its expense during the succeeding sixty (60) day period.

(a)                                 General Provisions.  All communications between the parties or their representatives in connection with the attempted resolution of any Dispute shall be deemed to have been delivered in furtherance of a Dispute settlement and shall be exempt from discovery and production, and shall not be admissible into evidence for any reason (whether as an admission or otherwise), in any arbitral or other proceeding for the resolution of any Dispute.

WITH RESPECT TO ANY DISPUTE TO WHICH THIS SECTION 9.3 APPLIES OR OTHERWISE IN RESPECT OF THIS AGREEMENT, THE PARTIES EXPRESSLY WAIVE AND FOREGO ANY RIGHT TO EXEMPLARY, SPECIAL, PUNITIVE, INDIRECT, REMOTE, SPECULATIVE OR CONSEQUENTIAL DAMAGES (INCLUDING IN RESPECT OF LOST PROFITS OR REVENUES), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY (INCLUDING NEGLIGENCE), WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES (PROVIDED THAT LIABILITY FOR ANY SUCH DAMAGES WITH RESPECT TO ANY THIRD PARTY CLAIM AND ANY STATUTORY PENALTIES UNDER ENVIRONMENTAL LAW SHALL BE CONSIDERED DIRECT DAMAGES).

The specific procedures set forth in this Section 9.3, including the time limits referenced therein, may be modified by agreement of both of the parties in writing.  All applicable statutes of limitations and defenses based upon the passage of time shall be tolled while the procedures specified in this Section 9.3 are pending.  The parties will take any necessary or appropriate action required to effectuate such tolling.  Unless otherwise agreed in writing, the parties will continue to provide service and honor all other commitments under this Agreement during the course of resolution of a Dispute pursuant to the provisions of this Section 9.3 with respect to all matters not subject to such Dispute.

(b)                                 Consideration by Senior Executives.  If a Dispute is not resolved in the normal course of business at the operational level, the parties shall attempt in good faith to resolve the Dispute by negotiation among representatives of the parties at a senior level of management of the parties.  Either party may initiate such executive negotiation process by providing a written notice to the other (the “Initial Notice”).  Within thirty (30) days after delivery of the Initial Notice, the receiving party shall submit to the other a written response (the “Response”).  The Initial Notice and the Response shall include (i) a statement of the Dispute and of each party’s position and (ii) the name and title of the executive who will represent that party and of any other Person who will accompany the executive.  The

17

parties agree that such executives shall have full and complete authority to resolve any Disputes submitted pursuant to this section (or paragraph).  Such executives will meet in person or by teleconference or video conference within sixty (60) days of the date of the Initial Notice to seek a resolution of the Dispute.  In the event that the executives are unable to agree to a format for such meeting, the meeting shall be convened by teleconference.  In the event that the executives are unable to resolve such Dispute within ninety (90) days of the date of the Initial Notice, the parties may seek any and all other remedies as may be available to them at law or equity.

(c)                                  Mediation.  The parties may, by mutual consent, select a mediator to aid the parties in their discussions and negotiations.  Any opinion expressed by the mediator shall be strictly advisory and shall not be binding on the parties, nor shall any opinion expressed by the mediator be admissible in any arbitration proceeding.  Each party shall bear its own fees, costs and expenses and an equal share of the expenses of the mediation.  Each party shall designate a business executive to have full and complete authority to resolve the Dispute and to represent its interests in the mediation, and each party may, in its sole discretion, include any number of other Representatives in the mediation process.

9.4                               Confidentiality.  The parties shall comply with the confidentiality provisions in Section 5.4 of the SEPARATION AND DISTRIBUTION AGREEMENT.

9.5                               Setoff.  All payments to be made by any party under this Agreement may be netted against payments due to such party under this Agreement, but otherwise shall be made without setoff, counterclaim or withholding, all of which are hereby expressly waived.

9.6                               Governing Law; Submission to Jurisdiction; Waiver of Trial.

(a)                                 This Agreement shall be governed by and construed and interpreted in accordance with the Laws of the State of Delaware without giving effect to the principles of conflicts of law thereof.

(b)                                 Each party to this Agreement hereby irrevocably (i) agrees that any Dispute shall be subject to the exclusive jurisdiction of the state and federal courts located in the State of Delaware, (ii) waives any claims of forum non conveniens, and agrees to submit to the jurisdiction of such courts and (iii) agrees that service of any process, summons, notice or document by U.S. registered mail to its respective address set forth in Section 9.10 shall be effective service of process for any litigation brought against it in any such court or for the taking of any other acts as may be necessary or appropriate in order to effectuate any judgment of said courts.

9.7                               Survival of Covenants.  Except as expressly set forth in this Agreement, the covenants and other agreements contained in this Agreement, and liability for the breach of any obligations contained herein or therein, shall survive the Distribution.

9.8                               Waivers of Default.  A waiver by a party of any default by the other party of any provision of this Agreement shall not be deemed a waiver by the waiving party of any subsequent or other default, nor shall it prejudice the rights of the waiving party.  No failure or delay by a party in exercising any right, power or privilege under this Agreement shall operate as a waiver thereof, nor shall a single or partial exercise thereof prejudice any other or further exercise thereof or the exercise of any other right, power or privilege.  No waiver by any party of any provision of this Agreement shall be effective unless explicitly set forth in writing and executed by the party so waiving.

9.9                               Force Majeure.  No party (or any Person acting on its behalf) shall have any liability or responsibility for failure to fulfill any obligation (other than a payment obligation) under this Agreement

18

so long as and to the extent to which the fulfillment of such obligation is prevented, frustrated, hindered or delayed as a consequence of circumstances of Force Majeure.  A party claiming the benefit of this provision shall, as soon as reasonably practicable after the occurrence of any such event, (a) notify the other parties of the nature and extent of any such Force Majeure condition and (b) use due diligence to remove any such causes and resume performance under this Agreement as soon as feasible.

9.10                        Notices.  All notices, requests, claims, demands and other communications under this Agreement shall be in writing and shall be given or made (and shall be deemed to have been duly given or made upon receipt) by delivery in person, by overnight courier service, by facsimile or electronic transmission with receipt confirmed (followed by delivery of an original via overnight courier service) or by registered or certified mail (postage prepaid, return receipt requested) to the respective parties at the following addresses (or at such other address for a party as shall be specified in a notice given in accordance with this section):

9.11                        Termination.  Notwithstanding any provision to the contrary, this Agreement may be terminated and the Distribution abandoned at any time prior to the Distribution Effective Time by and in the sole discretion of JDSU without the prior approval of any Person, including Holdings.  In the event of such termination, this Agreement shall become void and no party, or any of its officers and directors shall have any liability to any Person by reason of this Agreement.  After the Distribution Effective Time, this Agreement may not be terminated except by an agreement in writing signed by each of the parties.

9.12                        Changes in Law.

(a)  Any reference to a provision of the Code or a law of another jurisdiction shall include a reference to any applicable successor provision or law.

(b)  If, due to any change in applicable law or regulations or their interpretation by any court of law or other governing body having jurisdiction subsequent to the date of this Agreement, performance of any provision of this Agreement or any transaction contemplated thereby shall become impracticable or impossible, the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such provision.

9.13                        Severability.  If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced under any Law or as a matter of public policy, all other conditions and provisions of this Agreement shall remain in full force and effect.  Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement be consummated as originally contemplated to the greatest extent possible.

9.14                        Entire Agreement.  Except as otherwise expressly provided in this Agreement, this Agreement constitutes the entire agreement of the parties with respect to the subject matter of this Agreement and supersedes all prior agreements and undertakings, both written and oral, between or on behalf of the parties with respect to the subject matter of this Agreement.

and remedies at law or in equity, and all such rights and remedies shall be cumulative.  The parties agree that the remedies at law for any breach or threatened breach, including monetary damages, may be inadequate compensation for any loss and that any defense in any action for specific performance that a remedy at law would be adequate is waived.  Any requirements for the securing or posting of any bond with such remedy are waived by each of the parties.
