Exhibit 10.3
 
SUBLEASE TERMINATION AND RELEASE
 
THIS SUBLEASE TERMINATION AND RELEASE (“Agreement”) is hereby entered into
effective the 31st day of May, 2002 (“Effective Date”) by and between EON
COMMUNICATIONS CORPORATION, a Delaware corporation (f/k/a Cortelco Systems,
Inc.) (“Tenant”) and TC FOREST HILL DEVELOPMENT, LP, a Delaware limited
partnership (successor in interest to Trammell Crow Tennessee Development, Inc.)
(“Landlord”).
 
R E C I T A L S
 
1.  Landlord and Tenant entered into a Lease Agreement dated May 7, 1999, as
amended, by which Landlord has leased the premises (the “Premises”) more
particularly described therein to Tenant; and
 
2.  At Tenant’s request, Landlord conveyed the Premises to The Industrial
Development Board of the City of Memphis and County of Shelby, Tennessee (the
“IDB”), and the IDB, in turn, leased the Premises back to Landlord pursuant to
that certain Real Property Lease Agreement (“Pilot Lease”) effective December
31, 1999, by and between the IDB, as lessor, and Landlord, as lessee (“PILOT
Transaction”);
 
3.  As a result of the PILOT Transaction, the aforesaid Lease Agreement between
the parties was converted into a sublease (hereinafter, the “Sublease”); and
 
4.  Landlord and Tenant desire to terminate the Sublease prior to the end of the
term stated in the Sublease and agree to release each other from any further
liability in connection therewith except as set forth below, on the terms and
conditions set forth below.
 
NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties hereto hereby agree as follows:
 
1.  Termination of Sublease.    Subject to satisfaction of all Termination
Conditions (defined below) and to Section 7 below, the parties agree that the
Sublease shall terminate at 12:00 a.m. on June 1, 2002 (“Termination Date”), and
thereafter the Sublease and all rights and obligations of the parties thereunder
shall be deemed to have expired and terminated as fully and completely and with
the same force and effect as if such date were the termination date set forth in
the Sublease. In such event, Tenant shall be liable for and shall pay all sums
due under the Sublease as rent or otherwise through and including the
Termination Date, which are more particularly set forth on Exhibit A attached
hereto and incorporated herein by reference (“Final Sublease Payment”). After
payment of the Final Sublease Payment as expressly set forth on Exhibit A,
Tenant shall have no further liability for any common area maintenance charges
under the Sublease (including, but not limited to, Tenant’s obligations under
the Sublease to pay its proportionate share of Operating Costs, as defined in
the Sublease). Tenant shall pay the Final Sublease Payment to Landlord by wire
transfer for receipt by Landlord on or before the Termination Date in accordance
with the wire transfer instructions that have been separately provided by
Landlord to Tenant. Tenant shall in addition be liable for any Tenant
obligations under the Sublease that expressly survive termination of the
Sublease (including without

--------------------------------------------------------------------------------

limitation Tenant’s obligations under Section 27.01 of the Sublease). Unless and
until the Sublease is terminated as set forth in this Agreement, the Sublease is
and shall remain in full force and effect according to its original terms and
conditions and nothing contained in this Agreement shall be construed as a
waiver by the Landlord or Tenant of any of their rights and remedies under the
Sublease.
 
2.  Termination Conditions.    Landlord’s agreement to terminate the Sublease in
Section 1 above is conditioned upon and subject to strict satisfaction by Tenant
of each of the following conditions, time being of the essence with respect to
each such condition (“Termination Conditions”):
 
(a)  Tenant shall pay to Landlord a termination fee of One Million Six Hundred
Fifty Thousand Dollars ($1,650,000.00) payable as follows:
 
(i)  Tenant shall pay to Landlord Two Hundred Fifty Thousand and No/100 Dollars
($250,000.00) by wire transfer for receipt by Landlord on or before the
Termination Date, in accordance with the wire transfer instructions provided by
Landlord to Tenant;
 
(ii)  Tenant shall execute and deliver to Landlord a Promissory Note in the
principal amount of One Million Four Hundred Thousand and No/100 Dollars
($1,400,000) in the form attached hereto as Exhibit B (“Note”) on or before the
Termination Date;
 
(b)  Tenant shall cause to be delivered to Landlord the Letter of Credit
(defined below) securing Tenant’s obligations under the Note and this Agreement
on or before the Termination Date. Upon delivery of the new Letter of Credit to
Landlord and satisfaction of the other Termination Conditions, Landlord shall
promptly surrender to Tenant the existing $750,000 letter of credit in favor of
Landlord so that it may be terminated; and
 
(c)  The Premises shall be delivered to Landlord in accordance with Section 5
hereof on or before the Termination Date and Tenant shall have performed all of
its other obligations under the Sublease and/or this Agreement through the
Termination Date.
 
3.  Letter of Credit.    As a security for Tenant’s obligations under this
Agreement and the Note, Tenant shall deliver to Landlord an irrevocable Letter
of Credit substantially in the form set forth on Exhibit C attached hereto in
the amount of One Million Four Hundred Thousand and No/100 Dollars ($1,400,000)
(subject to adjustment as set froth below) naming Landlord as Beneficiary
(“Letter of Credit”). The Letter of Credit (or a replacement or renewal Letter
of Credit in the required amount and form) must remain in full force and effect
until ninety-one (91) days after payment in full of all sums due from Tenant to
Landlord under this Agreement and the Note. The issuer of the Letter of Credit
(the “Issuer”) must remain at all times acceptable to Landlord in its sole
discretion. An issuer which is rated A- or better by Standard & Poors or A3 or
better by Moodys shall be deemed acceptable. If Landlord reasonably objects to
the creditworthiness of the Issuer, Landlord shall give Tenant written notice of
said objection and within thirty (30) days Tenant shall replace the Letter of
Credit with a Letter of Credit of substantially identical terms issued by a bank
acceptable to Landlord. The

2

--------------------------------------------------------------------------------

face amount of the Letter of Credit may be reduced on June 15, September 15,
December 15 and March 15 of each year during the term of the Note to an amount
equal to the then current balance of the Note (as of each such applicable date)
plus One Hundred Seventy Five Thousand No/100 Dollars ($175,000). For example,
if the outstanding balance of the Note on March 15, 2003 is $875,000, the face
amount of the Letter of Credit could be reduced at that time to $1,050,000.
 
4.  Release and Indemnity.    Tenant, on behalf of itself, its successors and
assigns, hereby releases, indemnifies and holds harmless Landlord and its
current or former officers, members, shareholders, managers, partners,
employees, agents, attorneys, mortgagees, predecessors in interest, successors,
affiliates, heirs or assigns of any of them, from and against any liabilities,
losses, claims, demands, damages or expenses (including, without limitation,
reasonable attorneys fees) whatsoever, in law or in equity which Tenant ever
had, now has or hereafter can, shall or may have arising out of or related to
the Sublease or Tenant’s occupancy at the Premises, including without limitation
any claims, damages or expenses related to any casualty loss to Tenant’s
property, interruption of Tenant’s business related thereto or any third party
claims arising out of facts or circumstances that occurred prior to the
Effective Date of this Agreement.
 
5.  Condition of Premises.    Tenant shall have until the Termination Date to
remove its personalty, equipment and trade fixtures from the Premises, as and to
the extent permitted by the Sublease. On the Termination Date, Tenant shall
deliver the Premises to Landlord in the condition required pursuant to the terms
and provisions of the Sublease concerning termination of the Sublease (including
without limitation Section 7.01(b) of the Sublease).
 
6.  Representations and Warranties.
 
(a)  The parties represent and warrant to each other that they have not assigned
or transferred and shall not assign or transfer any of their respective rights
under the Sublease to any other party prior to the Termination Date.
 
(b)  Landlord hereby represents that it has full power and authority to enter
into this Agreement. This Agreement constitutes the valid and binding agreement
of Landlord, enforceable against Landlord in accordance with its terms.
 
(c)  Tenant hereby represents that it has full corporate power and authority to
enter into this Agreement. All actions required by the Board of Directors or
shareholders of Tenant to authorize the execution and delivery by Tenant of this
Agreement and the consummation by Tenant of the transactions contemplated hereby
have been taken. This Agreement constitutes the valid and binding agreement of
Tenant, enforceable against Tenant in accordance with its terms.
 
7.  Unconditional Obligations.    In the event Landlord is required to
relinquish or return any payments made by or on behalf of Tenant pursuant to
this Agreement or the Note or any proceeds of the Letter of Credit received by
Landlord, in whole or in part, by reason of a proceeding arising under the
United States Bankruptcy Code, or for any other reason, then, at Landlord’s sole
option, either (i) this Agreement and the Note shall continue to be effective or
be reinstated, as the case may be, at any time any such payment or proceeds
received by Landlord are rescinded or must be returned for any reason, or (ii)
all Tenant’s obligations under the

3

--------------------------------------------------------------------------------

Sublease shall automatically be reinstated and shall continue to be effective
notwithstanding any previous cancellation or release effected by Landlord
pursuant to this Agreement, as if no termination had occurred, and in such event
Landlord shall apply all sums received and retained by Landlord pursuant to this
Agreement against Tenant’s obligations under the Lease in such order as Landlord
shall elect in its sole discretion.
 
8.  PILOT Transaction.    Landlord may, at any time after the Termination Date,
request that the IDB revoke the PILOT Transaction and convey fee simple title to
the Premises to Landlord. At Landlord’s request, Tenant shall cooperate with
Landlord and the IDB to effectuate such revocation. In the event that the PILOT
Transaction is revoked, Landlord may obtain (i) an endorsement to any existing
leasehold title policy issued to Landlord for the Premises through Landlord’s
counsel, with such endorsement reflecting the conversion of Landlord’s leasehold
interest in the Premises into a fee interest as a result of the revocation of
the PILOT Transaction and the reconveyance of the Premises from the IDB to
Landlord and insuring Landlord’s fee simple interest on the Premises in the
amount of $7,500,000, or (ii) an Owner’s Title Policy issued by a title company
satisfactory to Landlord, through Landlord’s counsel, in the amount of
$7,500,000, and Tenant shall pay all premiums, costs and expenses related to (i)
or (ii). However, Landlord agrees to use commercially reasonable efforts to
pursue and obtain the lowest cost option [as between either (i) or (ii) above],
provided that Landlord’s fee interest in the Premises is reasonably insured in
the amount of $7,500,000. Except as a result of Landlord’s gross negligence or
willful misconduct, Tenant, on behalf of itself, its successors and assigns,
hereby indemnifies and holds harmless Landlord and its current or former
officers, members, shareholders, managers, partners, employees, agents,
attorneys, mortgagees, predecessors in interest, successors, affiliates, heirs
or assigns of any of them, from and against any liabilities, losses, claims,
demands, damages or expenses (including, without limitation, reasonable
attorneys fees) whatsoever, in law or in equity arising out of or related to the
PILOT Transaction, the revocation of the PILOT Transaction by Landlord, or
Tenant’s failure to comply with any of the documents, instruments or agreements
relating to or evidencing the Pilot Transaction (including without limitation,
Recapture Payments (as such term is defined in Section 9.04(d) and/or Section
9.08 of the Pilot Lease) due for any period prior to the Effective Date hereof,
and any other payment or expense due to the IDB pursuant to the Pilot Lease or
any other document, instrument or agreement whatsoever evidencing or relating to
the Pilot Transaction). It is understood and agreed that Tenant shall not be
responsible for Recapture Payments due to the IDB under the Pilot Lease that are
attributable solely to periods after the Effective Date.
 
9.  Loan Documentation.    In connection with termination of the Sublease and/or
the Pilot Transaction as set forth in this Agreement, Tenant agrees to reimburse
Landlord promptly for any cost or expense (including without limitation
reasonable attorney’s fees and recording costs) incurred or required to be paid
by Landlord relative to any modification, amendment, and/or termination of (i)
that certain $6,000,000.00 loan from Union Planters Bank (“UP”) to Landlord
pursuant to the Construction/Term Loan Agreement dated December 31, 1999,
secured by that certain Leasehold Construction Deed of Trust, Assignment of
Rents and Security Agreement dated December 31, 1999 executed by Landlord in
favor of Union Planters Bank, as previously amended or modified (the “UP Deed of
Trust”), and evidenced by all other documentation and instruments executed in
connection therewith; provided, that Tenant’s maximum liability under this
subsection 9(i) shall not exceed $10,000.00 (“Maximum UP Liability”); and (ii)

Series 1999-1,

4

--------------------------------------------------------------------------------

secured by the Deed of Trust executed by the IDB in favor of Landlord (the
“Landlord Deed of Trust”), and evidenced by all other documentation and
instruments executed in connection therewith. Except as a result of Landlord’s
gross negligence or willful misconduct, Tenant, on behalf of itself, its
successors and assigns, hereby indemnifies and holds harmless Landlord and its
current or former officers, members, shareholders, managers, partners,
employees, agents, attorneys, mortgagees, predecessors in interest, successors,
affiliates, heirs or assigns of any of them, from and against any liabilities,
losses, claims, demands, damages or expenses (including, without limitation,
reasonable attorneys fees) whatsoever, in law or in equity arising out of or
related to the occurrence of a default or event of default under the Landlord
Deed of Trust arising out of or related to Tenant’s default under the Pilot
Lease or Tenant’s failure to comply with any of the documents, instruments or
agreements relating to or evidencing the Pilot Transaction, but excluding any
Recapture Payments due to the IDB that are attributable solely to periods after
the Effective Date.
 
10.  Successors-in-Interest, Governing Law and Modification.    This Agreement
shall be binding upon and shall inure to the benefit of each party and its
respective successors and assigns, shall be governed by and construed in
accordance with the laws of the state where the Premises are located, and may
not be amended or modified other than in writing signed by the party to be

13.  Severability.    Should any provision of this Agreement be declared invalid
or unenforceable, whether in whole or in part, by any court of competent

recorded a memorandum of lease, Tenant shall execute and acknowledge within five
(5) days of receipt of same from Landlord a discharge and release of such
memorandum of lease. Landlord, at its sole cost and expense, shall have the

PROMISSORY NOTE
 
$1,400,000.00
  
Effective June 1, 2002
    
Memphis, Tennessee

 
FOR VALUE RECEIVED, the undersigned (“Maker”) promises to pay to the order of TC
Forest Hill Development, LP, a Delaware limited partnership (“Payee”; Payee and
any subsequent holder[s] hereof are hereinafter referred to collectively as
“Holder”), the principal sum of One Million Four Hundred Thousand and No/100
Dollars ($1,400,000), without interest (except as expressly provided below). All
payments hereon shall be made in collected funds at Payee’s main office, or at
such other location as the holder hereof directs in writing, and shall be
applied to principal, accrued interest (if any), and charges and expenses owing
on or in connection with this Note, in such order as the holder hereof elects,
except that payments shall be applied to accrued interest (if any) before
principal.
 
Principal shall be due and payable in twenty-four (24) equal monthly
installments of Fifty Eight Thousand Three Hundred Thirty Three Dollars and
33/100 ($58,333.33) each, with the first installment due and payable on July 1,
2002 and subsequent installments due and payable on the 1st day of each
succeeding month thereafter until June 1, 2004 (the “Maturity Date”), on which
date the entire outstanding principal balance shall be immediately due and
payable in full.
 
Maker may prepay the indebtedness evidenced hereby in whole or in part, at any
time, without premium or penalty, by paying the unpaid principal balance,
together with all other charges and expenses owing.
 
This Note is secured by a Letter of Credit naming Payee as Beneficiary and
expiring no earlier than September 15, 2004 (“Letter of Credit”).
 
Time is of the essence of this Note. It is hereby expressly agreed that in the
event that any default be made in the payment of principal or interest as
stipulated above (such event to be referred to as an “event of default”); or
should any event of default occur under any instrument or document now or
hereafter further evidencing, securing or otherwise relating to the indebtedness
evidenced hereby; or should Maker become the subject of bankruptcy or insolvency
proceedings; then, and in such event, the entire outstanding principal balance
of the indebtedness evidenced hereby, together with any other sums advanced
hereunder and/or under any other instrument or document now or hereafter
evidencing, securing or in any way relating to the indebtedness evidenced
hereby, together with all unpaid interest accrued thereon, shall, at the option
of Holder and without notice to Maker, at once become due and payable and may be
collected forthwith, regardless of the stipulated date of maturity. Upon the
occurrence of any event of default as set forth herein, at the option of Holder
and without notice to Maker, the entire outstanding principal balance shall bear
interest thereafter until paid at an annual rate equal to twelve percent (12%)
per annum, regardless of whether there has been an acceleration of the payment
of principal as set forth herein and Holder shall be entitled to draw the amount
of any sums due hereunder one or more times, from time to time, under the Letter
of Credit. Notwithstanding anything in this instrument to the contrary, in no
event shall the effective rate of

10

--------------------------------------------------------------------------------

interest payable in respect to the indebtedness evidenced hereby exceed the
maximum rate of interest allowed to be charged by applicable law (the “Maximum
Rate”). All such interest shall be paid at the time of, and as a condition
precedent to, the curing of any such default.
 
If any payment (other than the final payment due upon the Maturity Date) is past
due by five (5) days or more, Maker agrees to pay the Holder a late charge of
(i) 5% of such payment amount or (ii) any lesser maximum amount permitted under
applicable law. No late charge, however, shall be imposed on any payment made on
time and in full solely by reason of any previously accrued and unpaid late
charge.
 
In the event this Note is placed in the hands of an attorney for collection or
for enforcement or protection of the security, or if Holder incurs any costs
incident to the collection of the indebtedness evidenced hereby or the
enforcement or protection of the security, in any case after the occurrence of
an event of default, Maker and any endorsers hereof agree to pay a reasonable
attorney’s fee, all court and other costs, and the reasonable costs of any other
collection efforts.
 
Presentment for payment, demand, protest and notice of demand, protest and
nonpayment are hereby waived by Maker and all other parties hereto. No failure
to accelerate the indebtedness evidenced hereby by reason of default hereunder,
acceptance of a past-due installment or other indulgences granted from time to
time, shall be construed as a novation of this Note or as a waiver of such right
of acceleration or of the right of Holder thereafter to insist upon strict
compliance with the terms of this Note or to prevent the exercise of such right
of acceleration or any other right granted hereunder or by applicable laws.
Unless otherwise specifically agreed by Holder in writing, the liability of
Maker and all other persons now or hereafter liable for payment of the
indebtedness evidenced hereby, or any portion thereof, shall not be affected by
(1) any renewal hereof or other extension of the time for payment of the
indebtedness evidenced hereby or any amount due in respect thereof, (2) the
release of all or any part of any collateral now or hereafter securing the
payment of the indebtedness evidenced hereby or any portion thereof, or (3) the
release of or resort to any person now or hereafter liable for payment of the
indebtedness evidenced hereby or any portion thereof. This Note may not be
changed orally, but only by an agreement in writing signed by the party against
whom enforcement of any waiver, change, modification or discharge is sought.
 
This Note has been negotiated, executed and delivered in the State of Tennessee,
and is intended as a contract under and shall be construed and enforceable in
accordance with the laws of said state.

11

--------------------------------------------------------------------------------

 
As used herein, the terms “Maker” and “Holder” shall be deemed to include their
respective successors, legal representatives and assigns, whether by voluntary
action of the parties or by operation of law.
