                    Form of Lock-Up Agreement by and between
                  officers and directors of Comdial Corporation



             Officer, Director and Securityholder Lock-Up Agreement

                                 June ___, 2002

Comdial Corporation
106 Cattleman Road
Sarasota, Florida 34232

Ladies and Gentlemen:

The undersigned (the "Securityholder") understands that Comdial Corporation (the
"Corporation") has entered into certain Bridge Subscription Agreements of even
date hereof (the "Subscription Agreements") with certain investors providing for
the sale (the "Bridge Offering") by the Company of units consisting of 7% senior
subordinated secured convertible promissory notes (the "Notes"). 13.33% of the
principal amount of the Notes are convertible into shares of the Company's
common stock, par value $0.01 per share ("Common Stock").

1.   For good and valuable consideration, the receipt and sufficiency of which
     are hereby acknowledged, the Securityholder agrees that the Securityholder
     will not, without the prior written consent of the Company, directly or
     indirectly offer, sell, pledge, contract to sell (including any short
     sale), grant any option to purchase, enter into any contract to sell or
     otherwise dispose of or transfer any shares of Common Stock or other equity
     securities of the Company (including without limitation, any shares of
     Common Stock which may be deemed to be beneficially owned by the
     Securityholder in accordance with the rules and regulations of the
     Securities and Exchange Commission (the "SEC"), and any shares of Common
     Stock which may be issued upon exercise of any stock options or warrants or
     upon conversion or exchange of any convertible or exchangeable securities)
     or any rights, warrants, options or other securities that are convertible
     into, or exercisable or exchangeable for, Common Stock (collectively,
     "Rights", which term includes, without limitation, any shares of preferred
     stock which are convertible into Common Stock) or enter into any Hedging
     Transaction (as defined below) (each of the foregoing referred to as a
     "Disposition") for a period beginning on the date of the Initial Closing
     (as defined in the Subscription Agreements) and continuing through the
     earlier of (i) the date on which a registration statement covering the
     resale of the shares of Common Stock issuable upon conversion of a portion
     of the principal balance of the Notes (the "Note Conversion Stock"), is
     declared effective by the SEC, (ii) the date on which the Note Conversion
     Stock may be sold in the public market without an effective registration
     statement under the Securities Act of 1933, as amended; and (iii) the
     second anniversary of the Initial Closing (the "Lock-Up Period"). The
     foregoing restriction is expressly intended to preclude the Securityholder
     from engaging in any Hedging Transaction or other transaction which is
     designed to or is reasonably expected to lead to or result in a Disposition
     during the Lock-Up Period even if the securities would be disposed of by

     someone other than the Securityholder. "Hedging Transaction" means any
     short sale (whether or not against the box) or any purchase, sale or grant
     of any right (including, without limitation, any put or call option) with
     respect to any security (other than a broad-based market basket or index)
     that includes, relates to or derives any significant part of its value from
     the Common Stock or any Rights. The foregoing restrictions set forth in
     this paragraph shall apply to all shares of Common Stock and all Rights now
     owned or hereafter acquired by the Securityholder, except that such
     restrictions shall not apply to shares of Common Stock and Rights acquired
     in open market transactions after the completion of the Bridge Offering.

2.   Notwithstanding the foregoing, the Securityholder may transfer any or all
     of the Securityholder's Common Stock or Rights (i) if the Securityholder is
     a natural person, by gift, will or intestacy so long as the transfer is not
     for value; (ii) if the Securityholder is a natural person, to any trust for
     the direct or indirect benefit of the Securityholder or the immediate
     family of the Securityholder so long as the transfer is not for value;
     (iii) if the Securityholder is a partnership, to a partner of such
     partnership or a retired partner of such partnership who retires after the
     date hereof so long as the transfer is not for value; and (iv) if the
     Securityholder is a corporation, limited liability company or limited
     partnership to any of its wholly-owned subsidiaries; provided, however,
     that in any such case it shall be a condition to the transfer that, prior
     to or concurrently with such transfer, the transferee executes and delivers
     to the Company an agreement, in form and substance satisfactory to the
     Company, stating that the transferee is receiving and agrees to hold the
     Common Stock or Rights, as the case may be, subject to the provisions of
     this letter agreement, and there shall be no further transfer of such
     Common Stock or Rights, as the case may be, except in accordance with this
     letter agreement. For purposes of this Lock-Up Agreement, "immediate
     family" shall mean any relationship by blood, marriage, or adoption, not
     more remote than first cousin. Furthermore, in the event ComVest Venture
     Partners, L.P. ("ComVest") privately sells or transfers any of the
     securities it acquires in the Bridge Offering other than to its limited
     partners and other affiliated persons (except that a sale or transfer by
     such transferee shall be treated as if by ComVest), Securityholder may
     privately sell or transfer an equal percentage of its Common Stock or
     Rights.

3.   Without limiting the restrictions herein, any Disposition by the
     Securityholder shall remain at all times subject to applicable securities
     laws, including without limitation the resale restrictions imposed by Rule
     144 promulgated under the Securities Act of 1933, as amended.

4.   The Securityholder hereby agrees that, to the extent that the terms of this
     letter agreement conflict with or are in any way inconsistent with any
     registration rights agreement or similar agreement to which the
     Securityholder is a party or under which the Securityholder is entitled to
     any right or benefit, this letter agreement supersedes such registration
     rights agreement or similar agreements.

5.   The Securityholder understands that the Company will proceed with the
     Bridge Offering in reliance on this letter agreement.

                                       2

6.   This letter agreement shall be governed by the laws of the State of New
     York, without regard to any applicable choice of law provisions.

7.   This letter agreement shall terminate and have no force or effect if the
     Initial Closing (as defined in the Subscription Agreements) does not occur
     by 11:59 p.m. (New York time) on July 1, 2002.

8.   The Securityholder hereby represents and warrants that the Securityholder
     has full power and authority to enter into this letter agreement and that
     this letter agreement has been duly authorized (if applicable), executed
     and delivered by the Securityholder and is a valid and binding agreement of
     the Securityholder. All authority herein conferred or agreed to be
     conferred shall survive the death or incapacity of the Securityholder and
     any obligations of the Securityholder shall be binding upon the heirs,
     personal representatives, successors and assigns of the Securityholder.


Very truly yours
